I've got a problem with deploying one of my web-projects as an exploded project to Tomcat. This occured after installing MyEclipse 10. I've tried going back to MyEclipse 9.1, and have found to have no problems deploying there, same workspace, same project.

A popup comes up saying

Quote:

'Redeploy' has encountered a problem. An internal error occured during: "Redeploy".

In Details, the following message:

Quote:

An internal error occured during: "Redeploy". java.lang.NullPointerException

In the error log, the following messages are shown (several attempts to redeploy or add deployment):

Any ideas on what this is? Am I doing something wrong? Is there a way to get around this?

Thanks in advance for any suggestions. I'll go back to using MyEclipse 9.1 for now.

inforedno,

Sorry to hear you are running into this issue. You have attached configuration details, instead could you attach your installation details. You can find the same here - open MyEclipse IDE, from menu options click on MyEclipse > Installation Summary > Installation Details and copy and paste the same here.

Can you check your Java Build Path and Source tab to see if your source and output dirs are setup correctly?

As far as I can tell, my source and output folders are set up correctly.
I have 3 java-projects and a web-project that depends on the three. The output folder is set up to be /WebRoot/WEB-INF/classes as it should be.
I had a second source-path in my web-project, with a different output folder, containg som test-code which should NOT go into the deployment, and hence was targeted at a different folder. I thought this might be the cause of my problems, so I removed it as a source folder, but the deployment problem persists.

Let me know if you would like a zipped copy of my workspace, or anything else, to further investigate the problem.

/Erling

inforedno,

Thanks for the information. I'm going to file a problem report for this incident. Yes, please, send us your workspace, if possible. It it is too large to send, just the zipped projects will help. The workspace would be best, though. I haven't been able to replicate it with simple projects, along the lines of how you described your setup, so there must be something in your particular projects that is causing this.

You can attach your file(s) to an email to support@genuitec.com, with a subject of ATTN: TONY and a link in the email to this thread, please. Thanks.

Is this problem occurring on the integrated sandbox Tomcat server or an external one?

I've created a new workspace, copied the preferences over from the old one, and checked out only the necessary projects from our repository (Subversion). I will zip and post it later today.
The problem is with an external Tomcat-installation. I've never used the integrated one.
However, I have both a Tomcat 6 and a Tomcat 7 server configured, and it makes no difference which one I deploy to.
It also does not work deploying a packaged archive to <Custom Location>.

I have another web project which is linked to the same supporting (java) projects. I do not have the deploymentbuilder problem with this project.

While preparing my workspace for sending, I happened to discover what was probably wrong with my setup.

In my web project, I have linked (project properties > "Project References") to other projects, one of them a resource project.
I have not fully understood what the purpose of this property page has been, but I have now removed all project references from my web project, and no longer have the deployment builder issue.

Still, in case this problem should have been handled better (perhaps with a more understandable error message), I have sent over an e-mail with a link to a compressed copy of my example workspace, illustrating the issue.

inforedno,

I'm glad you've found a way round the problem and thanks for the workspace. We'll look into it to see if we can replicate your problem and fix it. We should be able to handle the same workspace across releases. If we find anything we'll post again.

I was able to replicate the problem with your workspace and with a new workspace. The problem appears related to the resource project. A simple web project with a referenced plain project will cause this problem in release 10. In release 9.1 it causes an information message about the output folders, presumably because the resource project has no output paths.

I'll update the problem report and, hopefully, we'll get this fixed soon.

Any update on this issue ?

Is there a patch that we can drop in so the deployment occurs ?

If the Web project is dependent on a simple POJO as a source dependency the convenience is awesome so I dont have to package them as .jars separately. This feature is absolutely required and very helpful.

Without this proj dep then I have to do a jar dep which I am willing to do, what is the most convenient way to do this ?

-Narahari

savithari,

Yes, the problem has been fixed and is in the 10.0.1 milestone stream (that is, 10.0.1 is still in development but you have access to what has been done so far). Please see this post for details.

Note that the issue you reported only occurs for non-java projects. If you have POJOs, presumably they would be in some kind of Java project and so would not be affected by this issue. There are associated settings (either project or workspace settings) which affect how dependent projects are deployed.

I am able to reproduce the issue with POJO or resource project. That is what the author of the thread has informed too.

Anyway I will try the milestone dev release.

How do you put the proxy info since I am behind a proxy server ?
Last time I used the offline installer for 10.0 but since the dev release is only online installer can you please let meknow how to put in the proxy info ?

-Narahari

Narahari,

You will be prompted for proxy settings if the on-line installer cannot contact the server.

If by POJO project you mean a plain java project, then that should work OK, since the problem occurs because there are no class files to deploy in a resource project. So I think you may be seeing a different problem. If installing 10.0.1 milestone stream doesn't fix it, please describe the problem, giving as many details as possible (OS, application server, any log messages, screenshots of the error and the dependency set up, and anything else you can think of that may help up track this down).

Hi team,

I'm experiencing the same problem on recently installed MyEclipse 10.6. The error message while building all the projects in my workspace is:

Java Build Path looks ok, and I deploy to an external JBoss 5. Any ideas?

Thanks

fcurrabm,

I see that you have deleted (or not installed) almost all the features of MyEclipse Blue. This is fine, except that you appear to not have a required component, the MyEclipse Editor. I'm not sure how this didn't get installed, or got deleted, but that may indicate a source of your problem, as there may be some required plug-ins that aren't available.

You can try running the installer again and choosing to repair an existing installation (you should choose to fix an existing installation, when given the choice to fix or revert). This would, hopefully, install any missing plug-ins. If not, please try a fresh install, ensuring that required MyEclipse features are not removed. You can install another copy of MyEclipse Blue, keeping the current installation, if you wish, though there probably is no benefit in doing so.

Please let us know if this helps.
