My Drools project has a number of GDSTs (Guided Decision Tables); those tables were created in the JBPM Workbench with hit policies of either 'First Hit' or 'Rule Order'. After upgrading from version 7.39 to 7.52 those policies are no longer being used. This is causing a lot of infinite loops.
Is there anyway to debug why this might be happening?
I will continue recompiling my projects at different version levels, 7.39, 7.40, etc; to try and determine where the support for Hit Policies stopped working but for now I was wondering if anyone else had experienced this issue and how they resolved it.
I am working on creating some JBPM objects that I can post, my actual project has data that I can not share. The additional details should be ready in a few hours. Sorry jumped the gun when posting the question, I know it needs more details, pom files at the very least.
Update Jun 8, 2021
First a quick background:
I am using the JBPM-Server Ver 7.52 that you can download from Drools website. Simply run the standalone.sh and you will have access to the Business Central Workbench.
Once in the Workbench I created some data objects and a few GDST's. The GDST's are created with Hit Policies of either 'First Hit' or 'Rule Order'. Also, when updating a field on the data object I am setting the 'Update Engine' option.
After the Workbench project has been created I can download the KJAR artifact and use it as a dependency in a Java API that pulls in data, loads the KieSession with rules from the artifact and data, executes the rules and processes the responses.
I know that the 'Update Engine' option, in combination with the loss of support for the Hit Policies, is causing the infinite loops.
I have also determined that this stopped working at version 7.52, everything works perfectly from versions 7.39 all the way through 7.51.
The only difference I have found between the two versions is that at 7.52 the 'source' for the GDST is now adding an activation-group parameter related the hit policy.

I am trying to upgrade the site from v 7.6 to v. 7.15.1.
I have done the upgrade on localhost which included updating the db.
Now I transferred my files from localhost o the test site and on there I am getting an error in log:
ERROR Umbraco.Core.UmbracoApplicationBase - An unhandled exception occurred
System.Data.SqlClient.SqlException (0x80131904): Invalid object name 'umbracoUserLogin'.
and I can't login to the backoffice.
It seems to be looking for umbracoUserLogin on test while it doesn't exist yet because on test the db is not updated yet.
How to update the db on test in this case while the files have already been updated on localhost and transferred to test site?
I have done 2 umbraco upgrades recently; one is from 7.5.7 to 7.13.1 and the recent one is from 7.13.1 to 7.15.1.
During my upgrade; I have seen this problem and fix in this issue can help you for your problem(and I didn't see this problem again after doing the upgrade again, but this time checking all the auto changing files and accepting them one at a time-see details below for this) but coming back to your question; "What's the best way to upgrade from umbraco 7.6 to 7.15.1(including db upgrade)"; here are the steps that you should follow;
Create a backup for your project and your umbraco db before you start. If you are using Git, then things will be super easy for this.
Open up Nuget Package Manager for your Umbraco project and do the package upgrade using the Nuget Package Manger window or the consol. Search for UmbracoCms version 7.15.1 for your case.
Once you start doing the upgrade, you will see some popup windows that will ask you to approve some auto file changes(including some config files changes). As you don't want to lose some of your pre-upgrade settings, don't accept them all or discard them all, check all of them one by one, and as a general rule; if you don't have any custom changes for those files, then simply approve the change, otherwise, check your changes and make sure you don't loose anything and discard some of these file changes as a result.
Once you're done with your UmbracoCms upgrade(which will automatically do some dependency package upgrades), build your project, make sure all is looking good then go to your local project's umbraco back-office url, this will trigger the rest of the umbraco upgrade process and simply complete the upgrade steps by following the screens- at this point your umbraco db changes will be done automatically and it is possible that you might have some issues with some old corrupt cached files, if this happens, then simply delete App_Data/TEMP files and App_Data umbraco.config file and try again. If you see some other problems during the installation, check the logs(browser developer tools can be handy to understand the problems in this case), and fix them one at a time. It is possible that you don'T need some of your old web.config settings and they might cause some issues, simply comment out those lines and see if this will fix some of the issues.
Once you are done with you local upgrade, deploy your code to your testing environment, and go to the umbraco url of your test environment and follow the screens to complete the installation for your testing environment. If you see any problems, please check my notes for step 4 above.
Do your umbraco upgrade for other testing environments(QA, UAT, Training etc) and complete your umbraco upgrade tests. Once the tests are done, then you are ready to go live. After the live deployment, you will have to complete the umbraco upgrade one last time, but this time for the live system.
Always get your back-ups for each environment before you do the upgrade, so you will be ready to rollback your changes if things go wrong(which might happen as you're doing a big umbraco upgrade).
Final note; there are some good articles for this, please take a look to understand the process better. Good luck!
I am using following command to deploy code to my AEM instance "mvn clean install -Daem.host=localhost -Daem.port=1202 -Dmaven.test.skip=true
"
After deployment pages are taking too long to load at least 7 mins.
I found No errors/Exceptions in error log.
There could be couple of factors causing this slowness -
Amount of memory allocated to AEM instance, default setting is - CQ_JVM_OPTS='-server -Xmx1024m -XX:MaxPermSize=256M -Djava.awt.headless=true' which is actually not sufficient for optimal performance. I have been using double of this configurations and sometimes even more.
When you deploy your package with code, the bundles are processed and services are registered. Depending on number of services/components being registered the time can go up. Sometimes there are hooks within code that cause few system level bundles to cycle as well, if that happens it would actually cause all the other bundles dependent on system bundle to cycle and registering the services again.
your code deployment could be triggering some workflow that either consumes lot of resources or is causing delayed activation on your bundle. The first scenario could happen if your deployment has something like images which when deployed causes OOTB image workflow to trigger (there could be other based on your code). Second scenario could be that you have bundle activator either waiting for another bundle which gets deployed later (and/or stays installed and not active) or you are building some sort of caching that waits for pages to be deployed and processed. There are countless such scenarios that can cause this issue.
What you could do is check the status of the bundles in /system/console/bundles pre and post deployment you can identify bundle related issues there. Another thing you could try is to do selective deployment of the code to figure out what module is causing issue that then dive deeper in to that module.
Also look at recent request logs to identify the flow of page load to see if there are services, filters etc in picture that are causing delays.
Let me know if any of this approach helps you identify the root cause and in case you need further help, will be here to assist.
I am trying to use eclipse kepler for Java EE 7.I already installed JBoss Tools and added JBoss Wildfly successfully as a server. However my changes are not automatically deployed. Is there anyway the app can be deployed automatically just as when using glassfish?
Using Eclipse, click twice on your WildFly Server to edit the following properties:
Publishing: choose "Automatically publish after a build event". I like to change the publishing interval to 1 second too.
Application Reload Behavior: check the "Customize application reload ..." checkbox and edit the regex pattern to \.jar$|\.class$
That's it. Good luck!
Both #varantes and #Sean are essentially correct, but these answers are not full.
Unfortunately the only way in a Java server environment to have full, zero-downtime hot deployment is to use paid JRebel or free spring-loaded tool.
But for small project there are some ways to speed up work by partial hot-deployment. Essentially:
When enabled option Automatically publish when resource change
then changes inside *.html, *.xhtml files are immediately
reflected as soon as you refresh the browser.
To make hot deployment work for *.jsp files too, then you should
inside ${wildfly-home}/standalone/configuration/standalone.xml
make following change:
<jsp-config/>
replace with:
<jsp-config development="true"/>
restart the server and enjoy hot deployment of web files.
But when modifying *.java source files, then only partial hot deployment is possible. As #varantes stated in his answer, enabling Application Reload Behavior with regex pattern set to \.jar$|\.class$ is an option, but has serious downside: whole module is restarted, thus:
It takes some time (depending on how big is a module).
Whole application state is lost.
So personally, I discourage this solution. JVM supports (in debug mode) code-swapping for methods' bodies. So as long as you are modifying only bodies of existing methods, you are at home (zero downtime, changes are reflected immediately). But you have to disable automatic publishing inside server settings otherwise the application's state will still be destroyed by that republish.
But if you are heavily crafting Java code (adding classes, annotations, constructors) then unfortunately I can only recommend set publishing into Never publish automatically (or shutdown server) and when you finish your work in Java files, then restart by hand your module (or turn-on server). Up to you.
It works for small Java projects, but for bigger ones, JRebel is invaluable (or just spring-loaded), because all approaches described above are not sufficient. Also because of such problems, solutions like Rails/ Django /Play! Framework gained so huge popularity.
I am assuming you are using the latest version of Wildfly (8.0 Beta 1 as of writing).
In the standalone.xml config file, look for <jsp-config/>. Add the attribute development="true" and it should hot-deploy. The resulting config will look like this:
<jsp-config development="true"/>
Add attributes (development, check-interval, modification-test-interval, recompile-on-fail) in configuration file in xPath = //servlet-container/jsp-config/
<servlet-container name="default" default-buffer-cache="default" stack-trace-on-error="local-only">
<jsp-config development="true" check-interval="1" modification-test-interval="1" recompile-on-fail="true"/>
</servlet-container>
(It works in WildFly-8.0.0.Final)
Start server in debug mode and It will track chances inside methods. Other changes It will ask to restart the server.
I have started a new job from a couple months, I work as front developer in a company where up until now everyone was using classic development patterns, but the goal is to move to a new ajax/rest services approach and that's what I do.
In our local development environment our apps run on Resin which runs inside Eclipse and get deployed as war files to C:\Resin\resin-pro-4.0.27\webapps
My problem is that I work mostly on css html and js files, static resources so I shouldn't need to restart Resin and wait 15 seconds (when it doesn't crash) to see the effect of every little piece of code I change.
Other problem is that I need to edit some files in external editors (sublime text for js, Crunch for LESS); I managed to make Eclipse open the external editor but even with the "Refresh using native hooks or polling" build option it takes a while to realize files have changed and restart Resin.
I also tried just working on the unpacked war in C:\Resin\resin-pro-4.0.27\webapps\appname but even there it takes like one minute before you can see the changes on the browser (is there some caching going on the server? can I disable it?)
I welcome any suggestion as all this is really hurting my productivity
inside Resin.xml <host><web-app> add:
<cache-mapping url-pattern="*.js" expires="0s"/>
<cache-mapping url-pattern="*.css" expires="0s"/>
<cache-mapping url-pattern="*.htm" expires="0s"/>
<cache-mapping url-pattern="*.html" expires="0s"/>
This used to work for me (in resin.xml)
<!--
- For production sites, change dependency-check-interval to something
- like 600s, so it only checks for updates every 10 minutes.
-->
<dependency-check-interval>2s</dependency-check-interval>
Also check resin.properties for a variable definition in newer versions.
However I'm currently having problems picking up changes without a full redeploy.
I've been trying to figure this out and so far haven't found a simple solution. Is it really that hard to deploy a database project (and a web site) using TFS 2010 as part of the build process?
I've found one example that involved lots of complicated checks and editing the workflow (which is a giant workflow btw).
I've even purchased the book "professional application lifecycle management with VS 2010", but apparently professionals don't deploy their applications since it isn't even mentioned in the book.
I know I'm retarded when it comes to TFS, but it seems like there should be any easy way to do this. Is there?
I can't speak for the database portion, but I just went through this on the web portion, the magic part is not very well documented component, namely the MSBuild Parameters.
In your build definition:
Process on the Left
Required > Items to Build > Configurations to Build
Edit, add a new one, for this example
Configuration: Dev (I cover how to create a configuration below)
Platform: Any CPU
Advanced > MSBuild Process
Use the following arguments (at least for me, your publish method may vary).
MsBuild Params:
/p:MSDeployServiceURL="http://myserver"
/p:MSDeployPublishMethod=RemoteAgent
/p:DeployOnBuild=True
/p:DeployTarget=MsDeployPublish
/p:CreatePackageOnPublish=True
/p:username=aduser
/p:password=adpassword
Requirements:
You need to install the MS Deploy Remote Agent Service on the destination web server, MSDeploy needs to be on the Build/Deployer server as well, but this should be the case by default.
The account you use in the params above needs admin access, at least to IIS...I'm not sure what the minimum permission requirements are.
You configure which WebSite/Virtual Directory the site goes to in the Web project you're deploying. Personally I have a build configuration for each environment, this makes the builds very easy to handle and organize. For example we have Release, Debug and Dev (there are more but for this example that's it). Only the Web project has a Dev configuration.
To do this, right click the solution, Configuration Manager..., On the web project click the configuration drop down, click New.... Give it a name, "Dev" for this example, copy settings from debug or release, whatever matches closest to what your deployment server environment should be. Make sure "Create new solution configurations" is checked, it is by default. After creating this, change the configuration dropdown on the solution to the new Dev one, and Any CPU...make sure your projects are all correct, I had some flipping to x86 and x64 randomly, not sure of the exact cause of that).
In your web project, right click, properties. On the left, click Package/Publish Web (you'll also want to mess with the other Package/Publish SQL tab, but I can't speak to that). In the options on the right click Create deployment package as a zip file. The default location is fine, the next textbox I didn't find documented anywhere. The format is this: WebSite/Virtual Directory, so if you have a site called "BuildSite" in IIS with no virtual directory (app == site root), you would have BuildSite only in this box. If it was in a virtual directory, you might have Default Web Site/BuildVirtualDirectory.
After you set all that, make sure to check-in the solution and web project so the build server has the configuration changes you made, then kick off a build :)
If you have more questions, I recommend you watch this video by Vishal Joshi, specifically around 22 and 59 minutes in, he covers the database portion as well...but I have no actual experience trying it since we're on top of a non MSSQL database.
