Bug Description

Binary package hint: eclipse

Reliably reproducible.

Steps to reproduce:
1) Open Eclipse
2) Go to "Help -> Help Contents"

Expected result:
Help content is loaded

Actual result:
------------------------
HTTP ERROR 500
Problem accessing /help/index.jsp. Reason:

    Unable to compile class for JSP:
------------------------

Used SW:
Ubuntu 10.04, amd64
openjdk-6-jdk: 6b18~pre3-0ubuntu1

It's regression in Eclipse 3.5.2 (Ubuntu package). I didn't have this issue in 3.5.1 (neither in Karmic nor in Lucid).
I also tested standalone package Eclipse 3.5.2 from http://www.eclipse.org/downloads/ and it works well too.

While I was waiting for the Ubuntu fix in early May I installed
eclipse (on 10.4
amd64) from the eclipse.org packages and help was working for me. The fix also
worked for me, but I haven't used eclipse for a month or so, so it is
entirely possible
some more recent update has broken things again.

Thanks for the encouragement, George,. FYI, status update - I reinstalled three packages:
  openjdk-6-jdk - OpenJDK Development Kit (JDK)
  default-jdk - Standard Java or Java compatible Development Kit
  default-jre - Standard Java or Java compatible Runtime
Hoped that this would do it, but sadly, it did not; have the same error. Other thoughts? Thanks.

FYI to any interested: I've abandoned my effort to locate the cause of this. It persists on my machine, but appears issolated to the Help-->Help Contents action. I have a working Help tab in the workspace that has a complete Help Contents. Having a functional help system is important to new users of Eclipse, which I am. Being new, its disconcerting to go to the Help menu and have the Help Contents blow up with a java error stack. I hope someone takes this initiative to fix it, and post the fix here. Regards.

Well, just couldn't leave it alone, like a scab. Finally figured out what was going on, so have it solved. For me, as suggested in previous posts on this thread, it was NOT that I wasn't using the java-6-openjdk. Turned out it was file permissions issues.

When I first installed, I installed to /usr/lib/eclipse {which is arguably the "right and best" location for an application}. But eclipse is peculiar in that its constantly checking & updating itself and its plugins. When first invoking a plugin (and help contents is that, like almost everything eclipse), its going to download and install packages specific to its invocation. If it can't because of file permissions issues, then it blows up with a java error stack.

My remedy was to make my user owner of all files in both my eclipse root (/usr/lib/eclipse/eclipse) and my workspace root (/home/java). To things right, however, I had to invoke eclipse as system root as follows:
    sudo /usr/lib/eclipse/eclipse /home/java
I then do whatever I was doing before, but now with system root privelege, and presto, checks happen, packages are downloaded, plugins are installed, configurations are made, whatever. I then close eclipse and do a:
   sudo chown -cR owner:group directory-root (for both my eclipse root and workspace root)
I then invoke eclipse as a user (its bad practice to be running as system owner).

Seems to work for me for the moment. There may be a better remedy. Regards.

Hi

@arkmundi: We cannot help you debug this when you use eclipse from eclipse.org, but I can tell you that Ubuntu has a vastly different setup than eclipse.org in this case. Particularly we do not embed the entire eclipse java compiler into libjasper-java[1] and we have patches in eclipse to make it load the correct bundles when the help is requested.
  A word of advice however, eclipse from eclipse.org is (as I recall) installed as a "single-user" install, which means it expects full read-write access to its "install location". You should generally not put this in /usr/lib or /usr/share, but instead unpack it in (e.g.) your home dir and run it from there.

To all others; I will strongly recommend *NOT* to start eclipse as root as it makes it possible for eclipse to modify some metadata about which plugins are installed via Ubuntu. It can make it very difficult for us to debug issues if eclipse has changed this metadata.

~Niels

[1] This is quite possible the reason for this bug in the first place and likely also to be the reason for why it works after installing default-jdk.

Niels, I don't nor do I recommend starting eclipse as root. The exercise was required so as to resolve the permissions issues, which I was able to do. It would be helpful, should you be part of the team that packages eclipse for ubuntu, if you would disclose the metadata you refer to, so I can better understand what you do to help seat eclipse, and perhaps make changes to my configuration.

With regards to the "proper" location for software on linux systems, I expect you'd find a great deal of disagreement with your assertions. Let's see, the directory is /usr/lib, which should be quite telling. Every other piece of installed software, by & large, finds its home there. At runtime, eclipse stores all its metadata in the workspace designated at startup, either as a command line parameter, in the eclipse.ini or in perference settings.

These changes should be documented in a README.Debian (maybe they are

The widespread advice "run some config tool" as root is becoming a problem
not just for eclipse, but many other apps -- often user ends up with files in
their home directory owned by root. It may be time to start adding checks to
the tools or using wrappers to discourage this practice.
