Can't deploy my project anymore

[JoyaleXandre]

Hi everybody,

Since friday I can't deploy my project anymore.

Went I start the war generation with the deploy button I instantly get an error message saying:
"Designer error occured.
Select Details >> for more information.
See the Error Log for more information.

Reason:
Parse error or internal Designer error,"

The stack trace is this:

I completely uninstalled the Google Plugin and reinstalled it. I still get this error.

My last chance is probably to reinstall Eclipse from scratch, but I would like to avoid reinstalling and configuring all my dev envirronnement.

Can somebody help me please. Am I the only one who got this problem since I tried to update the Google Plugin?

What java version are you using? Verify that you are using jdk 1.6

Do you fix the problem???  I have the same problem and not find the solution.

I install Eclipse, Gwt plugin and Designer.

Now my app not deploy.

Saludos.

Thanks.

[Juan Pablo Gardella]

Did you remove gwt-cache directories?

Yes, I removed the gwt-cache folder. I managed to compile my war file by executing the build.xml ant file manually. But I liked more when the deploy button was generating the xml for me. Now, I need to update it manually.

I ran into the same problem and could not figure out which configuration setting got hosed. Fortunately for me, I had a backup on another computer and just reverted back to that project and GWT 2.5.

That is one of the drawbacks of GWT--there is too much magic going on behind the scenes spread out in many directories and files. I will never try upgrading to a new version of GWT without backing up everything first.

Sorry this probably won't help you--I feel your pain.

Best,
Jeff

Has anyone pinpointed the cause of this?

I have tried to fix this with fresh installations of Eclipse Juno and Indigo with the GWT SDK and Designer plugins, have deleted the gwt-cache dirs, am using jre6, and yet the problem persists, very weird.  What else bothers me about this is that I can't figure out what I did that made this start happening; from my perspective this functionality was working just fine and then started failing one day when I did not make any substantial (from my perspective) changes to my environment.

Maybe next I should try to print out all my code on paper, buy a new computer, install and setup everything, and type in the code again.....

Thanks!

Hi, were you able in the end to solve the problem? How did you do? I have the same problem and I don't know what to do?

Please help.

Thanks.

Have you solved the problem? How?

[Alexandre Joyal]

I've made my own build.xml file to build my project. I don't understand that not a lot of person complain about that. It seems to be a major issue. I wonder if anybody that it's still working uses Eclipse Juno and GWT 2.5.1.

I did not figure out a solution (I reverted back to an older version of my project with get 2.5).

Perhaps you should create a brand new get 2.51 project and then just copy/paste your java source code files into this new project. Good luck.

How can be possible that nobody of the Eclipse/GWT Team has nothing to say about?!

[Jack Gage]

So, I worked on this for a while and basically didn't come up with anything...  I think that the context-menu deployment feature is not part of GWT 2.5.1.

To get around it, I have a two-step process: I compile my project with the GWT Toolbar Button > GWT Compile project option.  This compiles the JS in my web app folder.  Then I separately set up WAR deployment via the Project Properties > Deployment Assembly screen and deploy via standard Eclipse WAR export.

This isn't quite as easy as the context-menu deployment, but once it is set up it is pretty fast.  Also has the added benefit that if you only change server-side code, you can generate a new WAR very quickly since it doesn't compile the client side every time.

Hope this helps!

Thanks for the tip. I add another way to compile. You can just right-click your build.xml file, select Run As -> And Build from the context menu and voilà. Anyway this is something weird and really can't understand why they give us no support on solving this.

[Jeff Smith]

Magallo, I just built my war the same way--thanks for the tip.

Right click on build.xml

Run As Ant Build

Select first 'build.xml' item in list

Click OK

My war file was built successfully.

One other tip from me--edit your build.xml and remove the gwt-dev.jar from your filesets. This jar file bloats your war file by 33 MB and is only needed when running your project from Eclipse (you don't need or want it in the war file you deploy to Tomcat):

<!-- <fileset file="C:\Java\eclipse\gwt-2.5.0\gwt-dev.jar"/>   -->     

You'll also need to delete gwt-dev.jar from your /war/WEB-INF/lib folder if it is already there. Once you do that, your war file will shrink by 33 MB.

Best,

Jeff

Hi!

I fix that problem doing this:

-remove GWT lib from your project

-update gwt plugins  for eclipse

-put the lib back in your project

-done
