jogl won't load?

[dunmatt]

Hello all, I'm just starting out with jReality and I'm having some trouble getting jogl to work. No matter what I try it keeps saying "Possibly no jogl in classpath!". The trick is, the jar is there, and it is referenced in the ant classpath:

Code: Select all

  <path id='jreality.classpath'>
    <path refid='base.classpath'/>
    <pathelement path='${build.lib.dir}/jreality/beans.jar'/>
    <pathelement path='${build.lib.dir}/jreality/bsh.jar'/>
    <pathelement path='${build.lib.dir}/jreality/colorpicker.jar'/>
    <pathelement path='${build.lib.dir}/jreality/jogl.all.jar'/>
    <pathelement path='${build.lib.dir}/jreality/jReality.jar'/>
    <pathelement path='${build.lib.dir}/jreality/jrworkspace.jar'/>
    <pathelement path='${build.lib.dir}/jreality/jterm.jar'/>
    <pathelement path='${build.lib.dir}/jreality/glugen-rt.jar'/>
    <pathelement path='${build.lib.dir}/jreality/vrData.jar'/>
    <pathelement path='${build.lib.dir}/jreality/xstream.jar'/>
  </path>

And in the launch target:

Code: Select all

        <jvmarg value='-Djava.library.path=${build.lib.dir}/jreality/jogl'/>
        <env key='LD_LIBRARY_PATH' value='${env.LD_LIBRARY_PATH}:${build.lib.dir}/jreality/jogl'/>

If I change a single character in the pathelement ant gives me a warning that it couldn't find the jar I asked for, but the warning doesn't display when I have it spelled right, so I know it's finding the jar. I've also double checked that the appropriate .so files are indeed stored in jreality/jogl.

I'm using the latest version of jogl from http://jogamp.org/deployment/jogamp-current/jar/ , could that be the problem? I tried it with the jars linked to at http://www3.math.tu-berlin.de/jreality/ ... e-tutorial... or does it mean that jogl support is under construction (I interpreted it to mean that the wiki directions were under construction)

Help?

Oop, check that, it wasn't jogl.jar that was missing from the classpath, it was something else. I went ahead and added all 3rd party jars to the classpath and it got to a real error! Now it says

Code: Select all

On a whim I tried removing all the .so files and the error didn't change. I'm not sure if that helps or not.

Edit: If I switch the classpath to point to jogl.all.jar (the new one from http://jogamp.org/deployment/jogamp-current/jar/) I get the above exceptions. If I use the jogl.jar from your site I get the same "Possibly no jogl in classpath!".

Any suggestions?

Solved!! I'm not sure what the issue was, but deleting all the native files and jogl.jar and gluegen-rt.jar and redownloading them all from http://www3.math.tu-berlin.de/jreality/ ... e-tutorial seems to have done it! (whew!)

Hi dunmatt,

nice that you could solve your problem by your own. To solve your final question:
Yes, it was a version issue of jogl. Unfortunately we aren't running the newest version of jogl and jogl isn't supporting our used version anymore. So we have to maintain/keep the "old" jogl for our self at our website.

best regards
andre

I'm wondering how extensive are the differences? Perhaps it's one reason it's been giving me trouble trying to call from MATLAB on OSX.. . .

Not sure whether OSX or MATLAB or one of the toolboxes for it that I installed has too old of libraries or too new, but there may be conflicts somewhere...

Hi Ted,

I was also thinking about that. I'm pretty sure, that it is not possible to render with two different jogl-versions. So I think jReality and Matlab need the same jogl version in classpath. We are already working on a new jogl-backend but this may take some months...

There is already one hardcoded jogl2- branch at the jreality repository. You can check him out via http://fs.math.tu-berlin.de:8000/svn/jreality and than "branches" instead of "trunk". The name of the branch is jogamp

If you remove there all the jogl- and gluegen- jars and substitute them with the ones used for matlab, you have hopefully solved some of your problems.

best
andre
