Can't Get Java Working On Oz3.5.2 After Reflash

[Mongoosefred]

Hi ya,
Until sunday I had a perfectly working SL-5500 with OZ3.5.2 (Hentges), and had Java installed and working having followed Greg2's instructions in this thread:
Java For Oz 3.5.2

All was working great, then the PIM apps all failed.  So I copied all the data I wanted to keep and reflashed the rom using the original files I had used earlier.
Got Opera working, then tried Jeode (having written down what I did for Opera, but not Jeode...    )

So I tried a combination of the instructions from the thread and what I had done for Opera.  What I did was:

Code: [Select]

ipkg -dest sd --force-depends install jeode-for-oz3_0.4_arm.ipk
ipkg-link add jeode-for-oz3
Settings->Libraries->files->/mnt/card/opt/QtPalmtop/bin/evm
Reload Icons
When I try to run the apps in the Jeode tab, I get the evm splash screen then it comes back that it can't find runprimtest.
If I run it from the command line, I get a java.lang.NoclassDefFoundError mentioning  the java/awt/canvas class.
I set the CLASSPATH variable to the core.jar and awt.jar (which I can't remember doing last time) but still no luck.

Trouble is, I am wanting to do some install tests on a RSS feed agrigator I'm writing in Java and it's a little difficult to test the install....  
(jvMiniRSS version 0.2 will be out for download at xLevel.org.uk when I get this working...  small plug)

Help will be VERY greatfully recieved....
-Jim.

It appears that you need to do:

#ipkg-link mount /mnt/card

in order to find and add the demos on your SD-card... and if that still doesn't work you may have to symlink them like:

#ln -s /mnt/card/opt/QtPalmtop/bin/runprimtest /opt/QtPalmtop/bin/runprimtest

and the same for whatever else you have problems with

#ipkg-link mount /mnt/card

Cool... thats the bit I needed...  
This time I tried :

Code: [Select]

ipkg -dest sd --force-depends install jeode-for-oz3_0.4_arm.ipk
ipkg-link mount /mnt/card
Settings->Libraries->files->/mnt/card/opt/QtPalmtop/bin/evm
Reload Icons
Worked great and found a number of apps I had forgotten I had installed and had not shown up.  Now I got to figure out how to get ride of the seconf Joede tab...  but that's a small issue.
Thanks....

Install the opie-tabmanager.ipk and use it.

I was having the same problem, and just tried the above immediately after flashing (also with an SL5500 with Hentges OZ3.5.2). But it doesn't work for me.

I still get the same error Mongoosefred was originally having - i.e. if I run runprimtest from the icon, the evm splash screen pops up and then the error 'can't find application runprimtest', and if I run runprimtest from the console, I get the java.lang.NoClassDefFoundError: java/awt/canvas error.

Everything seems to be ok, links exist in /opt/QtPalmtop/bin/ as they should, etc.

Help?

Have you symlinked it as shown in my post in this thread? For some reason (unknown to me) this must also be done 'sometimes' after using ipkg-link.
If not, use this at terminal:

Code: [Select]

ln -s /mnt/card/opt/QtPalmtop/bin/runprimtest /opt/QtPalmtop/bin/runprimtest
ln -s /mnt/card/opt/QtPalmtop/bin/runquasar /opt/QtPalmtop/bin/runquasar

Yep, the links are there. If I run ln -s, I get 'File exists' as you'd expect.

I've actually managed to get it working now, but I'm still puzzled as to why the problem appeared in the first place.

I tried copying and editing runprimtest to manually specify the classpath to awt.jar and core.jar - didn't work. I then added the -v flag to the evm call, and the problem appeared - it was looking for awt.jar and core.jar in /opt/QtPalmtop.compat/lib where they didn't exist. So I ran

Code: [Select]

ln -s /mnt/card/opt/QtPalmtop/lib/*.jar /opt/QtPalmtop.compat/lib/
After that, it found the libraries, but not 'libevmawt.so'. Similarly to the jar files, it was looking under /opt/QtPalmtop.compat/ for it. Running

Code: [Select]

ln -s /mnt/card/opt/QtPalmtop/bin/libevmawt.so /opt/QtPalmtop.compat/bin/
fixed that problem, and both the jeode demos now run fine.

I can't help thinking though, that there must be something I'm missing to have this problem in the first place. Any ideas?

No, I haven't any new ideas and I can't see where you missed anything. I've had to symlink jar files for 'other' java apps... but never that jeode-for-oz3_0.4_arm.ipk. Strange, but at least it works now.
