I was trying to get a connection string using the App.config but ran into an issue that perplexed me for some time. When I ran the code, it would not find the right connection strings. There was a LocalTcpConnection but that was it (and I didn't even define that one, so no idea where that came from). Where are the connectionStrings that I defined in the App.config?
Turns out that only the App.config of the project you launch is actually used (see more here). Simply add the string to whatever project you launch with. This fact was not well defined in the Microsoft Docs I read or in many of the ConnectionString questions here on stack overflow, so I created this Q&A to help any souls as unfortunate as I to run into this problem.

Can someone point me in the direction of instructions for working out what has gone wrong with my Mobile Service App. It was working fine with a couple of simple tables. I then extended the data model using code first and migrations and now all I get when enter a url such as:
http://xxxxxxxx.azurewebsites.net/tables/firm?ZUMO-API-VERSION=2.0.0
is
{"message":"An error has occurred."}
I have now removed all new tables/data objects and controllers so that only one exists for a single table called "Firm" which has a single string property. I have switch OFF authentication/authorization in the Azure portal but I still get the same error.
I have tried both CustomErrors=Off and CustomErrors=RemoteOnly in the debug web config. I am publishing a debug build.
I have tried switching on logging and remote debugging etc in Azure but am unable to work out what is broken. I have tried remote debugging with a break point in my FirmController GetAllFirms method but error occurs before that point.
How do I get more useful information about what the problem is?
I have managed to solve this one myself. In fact now that I know what it is the answer was staring at me from the build output.
The issue was that when extending my model I referenced a .NET Standard 2.0 class library containing some enum definitions that are common to both the backend and the client.
I did not notice the warning that some assembly versions needed binding redirects added to web config. Double click on the warning message and VS2017 will add the necessary entries to web.config for you.
For more details see here on github.
I never did manage to get behind the {"message":"An error has occurred."} though. I solved this by rebuilding my backend project one step at a time and it was after adding the reference to the .NET standard project than I noticed the "Consider app.config remapping of assembly ..." messages in the build output window.
I am having a difficulty while attempting to debug some code in grails. It is difficult to put into text, so I have posted a screencast showing exactly what the problem is here. In short, while I am debugging the debugger starts jumping from place to place and not following the program logic I have in place. The only other similar question I have found is a year old, had no solution, and can be found here.
The best guess I have so far is that the debugger is displaying the text I have typed in, but is actually executing an older version of the class file which it has cached somewhere. Therefore, I tried:
cleaning the project
manually deleting all of the class files from the target folder and from the target-eclipse folder
Searching my entire hdd for additional files with similar names
removing my project from the workspace and re-adding it
closing and reopening the IDE
grails refresh-dependencies
Importing the project into a new IDE (I was using GGTS, I switched to IntelliJ)
None of those solutions had any effect. I realized that the issue was in a .groovy file, and I was writing almost pure Java, so I deleted the .groovy file, and re-created the class in a .java file. That solved my problem. Unfortunately I am having the problem again, and this time it is in a controller that heavily relies on the grails framework, so that solution is not an option. Other than also being in a .groovy file, another similarity is that the code breaks on an if statement.
My next steps:
Verify that the application is not executing the code I see by using print functions to monitor actual execution flow.
comment out the entire function and re-add functionality one line at a time to see if I can see what breaks it.
Delete the .groovy file, and re-create it as another .groovy file.
Any help is appreciated, and since I can't find any answers online I will continue to update this question as I learn more.
See my comment on the jira issue that you raised. You have found a problem with the groovy compiler and how it calculates line numbers. This is not a problem with executing the wrong class files or using a broken debugger. The debugger is doing exactly what it is expected to do. It is the compiler that is providing erroneous line number information.
The next step, as described in the issue, is to provide a simple project that recreates the bug. I tried to do so myself, but could not. So, please supply something that we can work with. Then we can notify the groovy compiler team.
I've been trying to get the following Eclipselink samples to work, with less than 0% success:
A)
http://wiki.eclipse.org/EclipseLink/Examples/JPARS/Simple
B)
git://git.eclipse.org/gitroot/eclipselink/examples/mysports.git
Both samples are quite recent and should work "out of the box". My results:
A) starts and deploys on glassfish, but application is totally unresponsive
B) does not deploy, since glassfish does not find the data-source mentioned in the persistence xml's: java:global/mysports
For both I tried to get information on how they are supposed to work, but after two days of searching for documentation, I can safely state: there is literally NOTHING documented.
For A) I am totally clueless, there is nothing to configure for this sample, but the provided URLs for interacting with the REST service always return with 404 and no log or error message whatsoever.
For B) Beside the broken data source (I guess my fault), I tried setting default JDBC data-sources, to see if at least the REST service itself works: it looks dead, I get exceptions when opening the sample JSF pages (the reference variables inside the pages all resolve to NULL).
Anybody ever tried to actually run these samples? I am totally frustrated after many hours of being far away to anything testable...
Maybe some questions as a starting point:
- How does the JPA-RS get registered in the appserver? how do I tell if it was at all? And which URL it maps to?
- How does this magic "java:global/mysports" data source work?
- The maven configuration acts funny, I couldn't get any of the two samples to properly debug (no breakpoints were hit at any point in time). Any ideas?
If you are using Glassfish earlier than Glassfish 4.0 (http://dlc.sun.com.edgesuite.net/glassfish/4.0/promoted/) you will need to download newer version of EclipseLink 2.4.2 binaries from http://www.eclipse.org/eclipselink/downloads/nightly.php (2.4.2 Nightly Build Results) and replace following files under $GLASSFISH_HOME/glassfish/modules with corresponding jars you downloaded above:
org.eclipse.persistence.antlr.jar
org.eclipse.persistence.jpa.jar
org.eclipse.persistence.asm.jar
org.eclipse.persistence.jpa.modelgen.jar
org.eclipse.persistence.core.jar
org.eclipse.persistence.oracle.jar
javax.persistence.jar
org.eclipse.persistence.dbws.jar
org.eclipse.persistence.jpa.jpql.jar
Make sure you clear Glassfish osgi cache by removing the $GLASSFISH_HOME\glassfish\domains\your_domain\osgi-cache directory after you replaced the bundles listed above, and before you restart the Glassfish.
These are both advanced examples, unless you are looking for these specific features, I would recommend starting out with simpler examples.
There are many EclipseLink JPA examples documented here,
http://wiki.eclipse.org/EclipseLink/Examples
Most of the examples are still in SVN here,
http://dev.eclipse.org/svnroot/rt/org.eclipse.persistence/trunk/examples/
For documentation on the JPA-RS examples see,
http://wiki.eclipse.org/EclipseLink/Examples/JPA#JPA-RS
Try adding question to the example's wiki discussion page if you are having specific problems.
The MySports example is very advanced. Unless you are looking for extendable entities and multi-tenancy, I would not recommend starting with this example.
To add to James' comments, if you are specifically interested in JPA-RS, perhaps these additional comments will help. I also recommend asking questions on the wiki discussion page.
JPA-RS gets registered in the appserver by the existence of the org.eclipse.persistence.jpars_[version].jar in the WEB-INF/lib directory. This jar contains the web-fragment.xml which is what defines the JPA-RS service. You will know if it was deployed if the following URL pattern returns persistence unit metadata:
http://<server>:<port>/<applicationName>/persistence
Some additional documentation for JPA-RS:
- http://www.eclipse.org/eclipselink/documentation/2.4/solutions/restful_jpa001.htm
- wiki.eclipse.org/EclipseLink/Development/2.4.0/JPA-RS/REST-API
One thing that will help you debug is to view the Glassfish server log. If you are running in Eclipse, right click on your Glassfish server in the Server view, go to Glassfish->View Log File, which will open the server log in your console view. This will show you what is happening with deployment, and will alert you to any errors. Also be sure to double check your URLs.
Ok, ladies. A friend of mine had the brilliant idea of forcing ALL logging on eclipselink-jpars library (by setting this value in every single file we could think of) and indeed we found an exception that is FOR NO GOOD REASON hidden in the lowest log level:
javax.xml.bind.PropertyException: name: eclipselink.json.include-root value: false
Whatever that means, but that again convinces me that I will not use this feature/lib for the time being. An exception should be visible on all log levels, especially if I go down to FINE (as stated in the samples!)! I almost lost three days just because of this.
When deploying a Word Add in , which publishes without error. I get the following error after the files have been copied.
I do not have much to go on. This is the stack trace.
************** Exception Text **************

here's an answer to what you are looking for:-
the problem:-
open Process Monitor during the failed update and see if Winword.exe is browsing the following registry key->
HKCU\Software\Classes\Software\Microsoft\Windows\CurrentVersion\Deployment\SideBySide\2.0\Marks\mmiw..vsto_510943deeecbc925_0002.0000_2055f5031035ea75\appid
in this someone managed to check the Compatibility Mode checkbox for Word, running it default under Windows XP SP2 (see if you can make the program compatibile with your system in short).
if this is not the issue
Then read further into this :- deploy a VS 2008 SP1 Word 2007
There is another post i have found on this topic HERE. it shows a possible work around that you could try to get a result? i'm not entirely sure but in this, the developer was using outlook 2008, i think he removed the instances of outlook within his code and re-implemented parts of it and left out others. Perhaps this could be a temporary fix or help you understand what the problem is?
(I'm sorry my answers aren't so clear, i don't have much time for stack overflow at the moment, i will clean up the answer when i have more time(it will flow)) ++ this is all i can find regarding this error, but there are people with the same issue on the Microsoft forums, maybe you could find an answer faster on there? if you follow the links I've posted you should be able to find some information that might be able to give you a decent fix.
PS. if this doesn't work, reply asap and i will search asap, i think I've found something else which might be of use, just have to understand it myself before i post.
I recently came across this problem too after messing with some dependencies. None of the noted solutions worked (either on MSDN or here).
How I fixed it:
Find an old published version that worked.
Find the .dll.manifest file.
Diff that manifest with the one that is erroring.
In my case, I saw that a .dll was incorrectly referenced there (I thus had a v2 of it and a v4). I removed this reference and, thank god, it works.
newbie to Entity Framework here. Using VS 2010 and SQL Server 2008 express DB.
I was having trouble refreshing an Entity Data Model after adding new tables. So, I followed a suggestion I found here to just delete and regenerate the model.
I get to the "Choose Your Data Connection" section of the Entity Data Model Wizard and "Save entity connection settings in Web.config as:" is checked. However, my existing name has a 1 appended to it. For example MyDatabaseEntities is now MyDatabaseEntities1. Of course, I don't want the "1" appended. I killed the existing connection string in Web.config and removed all references to that name in my solution. Yet when I try to continue I'm presented with the following error:
"'MyDatabaseEntites' conflicts with an existing property name in the Application Settings. Please choose a different name"
I can't find a reference to that name anywhere in the solution. I can uncheck that option and it will continue, but it STILL won't add two of the tables in the database. Next, I completely shut everything down, rebooted, and tried again. This time I didn't get the error above, but two of my three new tables still do not get added to the edmx model.
Any ideas are appreciated. Also this seems like it's still pretty buggy even in VS2010/.NET 4. Help restore my faith...I feel like abandoning Entity Framework at this point. Based on my experience so far and some of the other issues posted here, I feel like I'm going to spend more time chasing Entity Framework strangeness than writing useful code.
UPDATE: I found a resolution. The designer doesn't display errors. You have have to look in the native XML (edmx file) to see the errors. See here: ADO.NET Entity Framework: Update Wizard will not add tables
The error is caused by leftover connection strings in settings in "App.Config" file (see solution explorer) and it's in this section:
"connectionStrings" (surrounded by angle brackets)
Just delete it from there.
Restart IIS if you develop web app.
Restart Visual Studio After Deleting The EntityDataModel Connection
String Line from web.config or app.config
Add New Entity Data Model and rename it like old name,
I don't know the specific answer to your problem, but I think I can recommend an approach that will clear up this conflict.
I generally break my EF work into a separate library. If I'm working on Cyberdyne.Terminator, I make an EF class library called Cyberdyne.Terminator.Data. That way, if you want to blow away the model and start over, everything is separate from your dependent files, and in particular, your web.config.
None of this is likely to fix the missing tables, probably. The one thing I've seen where this happens is if I add a table, and then delete it. It will not appear again in the "Add Tables" dialog (and you have to rename it to get it to show). But I thought that was fixed in EF 4.0. Dunno. If the problem persists you might try renaming the table, re-adding it, and then renaming it back if it shows up.
EF is a pain in the ass to be sure. The only thing I can tell you is that I've generally had to work through these headaches, learn the issue, and never be bothered by them again. If you can't stand EF, you might also look at NHibernate - I have a very strong impression of that as well.
Double check your connection strings, and keep scrolling to the right. Most often, when this happens to me, Visual Studio has appended a connection string behind another. I've done this a couple times, and wondered where my app config was (no, there is no app config, just web config in mvc), so the dialog is a little confusing. Sure enough, most likely that connection string is lurking directly behind another!
Just press
Ctrl+F
keys and in dropdown list select 'EntireSolution/CurrentProject', then press enter. where ever this name generated it will show you.
I get into web.config file. so delete that generated complete connection line from there. and re add it again. Then hope you may not get this message again.Thank you..
Actually this is frustrating, since you trying to see in app.config that if there's a another string and you see only 1 string, Actually What VS does is sometimes append second string in the same line. see this picture below
Does it look like there are 2 ConnectionStrings? (ACTUALLY YES)
Now, see this pic:
Also you can press Ctrl+ED to format the config file and see if there's another second string hiding somewhere. Hope this will help someone.
im so sorry for my english
but the solution is simply.
you have to delete the ado.net
then, go to app.conf and delete the connection string<>,
DEBUG your project and finally add the new database through ado.net
TO ADD ADO.NET
RIGHT CLICK ON YOUR PROJECT NAME, THEN, ADD NEW ITEM, DATA AND SEARCH ADO.NET...
I hope help you, have good day!
