I am facing a wierd issue, I have a command and it has a handler, and i am calling the command using IHandler service from the code, but i am getting this wierd issue for the first time, and from the second time onwards it works normally
Unable to understand why, Under what circumstances this issue is caused?
Is there any way to force the load of the plugin forcefully during the start of the eclipse application itself?
Regards,

I'm having a hard time using eclipse because of the following issue.
It goes like this. I'll code and try to run it. Then, it will throw some errors (of any kind). And so, after I have changed a part of the code, comment out which codes I suspect makes the error, or delete something, I then restart the websphere application server in order to republish my work. Next is to test my work using SoapUI then all of a sudden eclipse throws an error which is the same as before. I've tried to search in here answers to this questions but it involves codes which don't need in my project and also answers that I can't understand well (since I am very new to programming). However, I have found a way to resolve this but it's very inconvenient. To be able for eclipse to detect changes in the src folder, I should restart eclipse after editing my codes then remove my project in the server, start the server and then publish my work in websphere all over again. It solves my problem but I do all of these stuff every now and then even if I only comment out a single line in the code. What I want is to avoid doing this process of resolving the issue since it consumes so much of my time whenever I republish the project in the server.
Can somebody help me with this? Any suggestions would be very helpful. Thanks a lot!
It is a bit strange that you need to restart eclipse. The normal way would be to just re run your application server.
Try only he 3 second steps you mentioned (remove my project in the server, start the server and then publish my work in websphere) and if that works try again without removing the project. Just restart the servers.
And let us know if that worked!
I have a problem running programs on eclipse. It's not running any new program.It's stuck on few last projects I previously ran. Overtime I'm trying to run a new program it runs another program that I'm done working on. I don't know what's causing it. I tried everything in my knowledge but nothing seems to be useful. If anyone can help me, I would very much appreciate it.
Don't click on Run button in eclipse it sometime run the cached program i.e., already runned programmedIt is not a good practicebeing a experienced eclipse user I can advise you to try to right click on your program after saving it then click Run As option and further option(optoin vary like in JSE program it shows java Application and in JEE program it shows server option)hope you will try this and it can solve your problem
I am changing the installer on an application and in the install4j IDE I am getting the error "Error instantiating (class-path-to-action)". I don't know what is causing the error or what to do to fix it.
This is the second time I have come across this while using the install4j IDE, although the first time the error disappeared once I had built the project and closed eclipse.
This time round I have tried opening up the install4j file right after a restart and I am getting the same error, with no luck in getting rid of it.
Can someone enlighten me on what could be causing this, or how to fix it?
You can find more information in the file %TEMP%\install4j_error.log about the exception. Probably the class path configured on the Installer->Custom code & Resources is not correct.
I've got a Android AppEngine Connected Project I'm trying to build using GWT2.4 RequestFactory and Objectify on my Eclipse IDE.
Apparently I need to run the RequestFactory Validation Tool because I'm using ServiceName and ProxyForName annotations (these are required especially when working on the Android client side). My problem is the Eclipse can't validate it and the solution provided at http://code.google.com/p/google-web-toolkit/wiki/RequestFactoryInterfaceValidation#IDE_configuration is enough to make me rip my eyes out.
Since I'm working on a Windows machine, the shell script provided is not very useful. Trying to run Validation Tool from a cmd propt returns the error message:"This tool must be run with a JDK, not a JRE"
Can someone explain how this Tool is supposed to be run? Is there a way to use it as an External Tool in eclipse?
Normally if you follow carefully the instructions in the link you show, and run the GWT Development Mode from Eclipse, the Validation should be done automatically at the time you access the development URL with your browser.
For the record, I've actually had some problems with it, but launching the application several times maked it work.
Well, I ran into the same problem as well. When I tried annotation processing (under Java Compiler-> Annotation processing )was being disabled. So RequestFactoryDeobfuscatorBuilder was not being generated. Try enabling that and rebuilding your project.
I've just recovered from two days of hunting this bug down in a project that used to run validation properly but stopped.
In my case I had a new-ish generic BaseRequestContext and a specific sub-interface that extended it. My parent interface declared a method that didn't match the Locator's exactly (e.g. getThing(T) vs get(T)) and this wasn't reported as an error but did stop the validation tool from completing.
Apt is also removed in Java 8 : http://openjdk.java.net/jeps/117 . So beware.
Switching back to Java 7 will fix the issue if you are using Java 8.
I understood why the error happens sometimes in a project: the compiler was complaining it cannot find the directory .apt . But when I tried to create it manually it was not possible (under windows). I think the validation tool mutes the exception of not being able to create the directory: try renaming .apt in your validation tool calls (do a text search in your project)
"Hot Code Replace Failed - add method not implemented".
I get this error message every time I change something in my test class (and save it).
Can't figure out what it means. Can somebody help?
Possibly, you have a test which is still running (in debug mode). Try finishing all tests (you can see them in the debug view: window->show view->debug) and try again...
See this thread:
This means you changed a class while it was debugging an application and it could not update the class for the application while it was running.
The error suggests you may be running an older JVM, i.e. pre-1.4.2 but this error can occur with any JVM if the change is incompatible with the previous version of the class.
Check carefully what JRE you are using in your debug session.
Also check you are deploying classes compiled with the debug attribute set. (see this thread)
Finally, as indicated here:
did you switch "Project->Build Automatically" off?
Hot code replacement works (only?) if automatic build is switched on...
I was running into this issues too. I found a build hiding in the backgound that was giving me fits. Check to make sure you have all tests/builds closed or completed. Nonetheless, you can still run the new code.
Whenever this error message appears it also gives options to terminate or restart. Select Terminate and it will terminate any running debug case which you are unable to locate.
if you have multiple projects involved, and multiple jre's installed, make sure all dependent projects are using the same javac/jre
Make sure your application server JRE and Eclipse JRE version should be same or else it will throw unsupported class version and hot code debug will not work.
I went to the same Problem,But my Debugging session ended hours ago.But still ECLIPSE error kept coming.
So I just simply restart the ECLIPSE IDE, then the problem just solved.
