Azueraus + Java = something isnt working right

[Propane]

well, earlier today I emerged Azuerus-bin and it went fine

However when I go to run azueraus I get:

Code: Select all

Attempting to start Azureus...
/usr/bin/azureus: line 54: java: command not found
If you recieved an error about a missing java class, you need to setup
your classpath correctly.
This should do the trick (as root):
java-config --add-system-classpath=junit,log4j,commons-cli,systray4j
env-update && source /etc/profile

Currently, your classpath (including azureus additions) is:
swt.jar:swt-pi.jar:swt-mozilla.jar:seda.jar:Azureus2.jar:

Then this happens:

vader kevin # java-config --add-system-classpath=junit,log4j,commons-cli,systray4j
Malformed CLASSPATH in /etc/env.d/21java-classpath

any ideas?

The first thing azureus complains about is that the command "java" could not be found.
Perhaps I'm confusing something, but to me that sounds as if "java" was not in your $PATH.

What is the output of these commands?

Code: Select all

which java
echo $PATH

The other error is related to the system's classpath settings.
Please post the content of /etc/env.d/21java-classpath.

Code: Select all

kevin@vader ~ $ which java

kevin@vader ~ $ echo $PATH

and the classpath is empty which I dont understand...[/code]

and the classpath is empty which I dont understand...

After experimenting a bit, I found the same problem.
It seems to happen when there is a package included in the file that doesn't exist in the system anymore, or perhaps it has something to do with permissions?
As a reaction, java-config seems to completely remove everything from that file, leaving it empty.

Every subsequent try to add something to the system's classpath finds that the file doesn't contain the CLASSPATH variable as it should, the error message you posted above is displayed and the file is left empty again.

A workaround to this seems to be removing the file /etc/env.d/21java-classpath .
When you then use the java-config --add-system-classpath= ... command, the file will be created and the specified packages will be registered.
Another possibility would be to add the string CLASSPATH= to the file, which then contains a valid classpath-variable: an empty one, but valid.

The downside to these workarounds is that they don't restore your original classpath settings, but you can't always win ;)

hmm, now Im getting another error...

Code: Select all

jc_options: Could not find package commons-cli

however the package is installed

Code: Select all

vader kevin # emerge -p commons-cli

These are the packages that I would merge, in order:

Calculating dependencies ...done!
[ebuild   R   ] dev-java/commons-cli-1.0-r4  
vader kevin # 

[tomvollerthun]

You can see which java-packages are actually available for addition to the classpath with

Code: Select all

java-config -l

When I do this, I find that the commons-cli package is actually registered as "commons-cli-1",
so it might work when replacing your original command with

Code: Select all

java-config --add-system-classpath=junit,log4j,commons-cli-1,systray4j

Remember that you may have to remove /etc/env.d/21java-classpath before this works.
(java-config seems to be abit buggy ;)

I have followed below instructions but it doesn't work for me:

Code: Select all

jaime@neworder ~ $ azureus
Attempting to start Azureus...

It seems that classpath is correctly, isn't it? Have you any idea?
