[Jxplorer-users] jxplorer 3.3.0.2 MAC OS X startup failure

Discussion:

Hi RenÃ©,

what version of java are you running? The latest version uses wildcards
in the class path, which means you need java 1.6 or better.

If that *is* the problem, and you need to use an older version of java
(1.5 is supported in code) you'll need to list the jar files in /jar
explicitly (or revert to an older version of jxplorer - they're still
available on sourceforge).

Hope that helps!

- Chris

Hello Chris,
With version 3.3 it was working fine. With version 3.3.0.2 I get the
following error when I start jxplorer

Can you help me to solve this issue?

Hi RenÃ©

1.6 or better is needed, so 1.7 should run fine...

... so I'm not sure what the problem is; it seems that it isn't finding the
jar files it needs to run.

In no particular order, you could check:
a) are you running the shell script in the jxplorer root directory?
b) if so, are there jar files in the /jar directory?
c) if so, is there anything funny happening with file permissions?

How did you install it by the way, and what version of OSX are you using?
Apparently OSX 10.7 breaks my standard installer, and Apple have been doing
funny things with java support lately - however I run OSX 10.6.8, so I
haven't seen these things myself...

cheers,

- Chris

Hi Chris,
I use the latest version 1.7 of java
Version 1.5 of java is due security issues not safe any more to use.
At one point you mention to use 1.6 or higher. And then you mention 1.5 is
supported in the code. So which version is required? I hope it will be
version 1.7

Rene

What happens if you just run the command directly? (from the root JXplorer
directory obviously, one level above /jars)

java -Dfile.encoding=utf-8 -cp .:jars/*:jasper/lib/*

com.ca.directory.jxplorer.
JXplorer

I use OS X 10.8.2
The installer didn't work. But when moving the contents of the zip into
the applications folder then it did replace the old 3.3.0 version. Then I
have an icon to start the jxplorer, but that's not working. So I run the
jxplorer.sh with console parameter from a terminal and then I got the error
message I sent earlier.
A) yes
B) yes
C) no problems detected with permissions.

Well then I'm stumped; run:

java -cp .:jars/* com.ca.directory.jxplorer.JXplorer

and if that doesn't work either
a) the jar file is corrupt, or
b) the version of java is *not* 1.6 or better, or
c) java is broken

Just to make sure, try running (from the same location)

java -version

and

pwd

and

ls -l

and send the output through... but I have to say this doesn't make a whole
heap of sense :-(

Are you running any other java programs by the way? And do they work o.k.?

Sorry this is turning into such a saga...

Excellent; it sounds like that's done the trick! (many thanks Sergio :-)!)

It looks like I should do a new release of the OSX stuff asap...

cheers,

- Chris

Hi Chris,
escaping the * did the trickâŠ.
java -cp '.:jars/*' com.ca.directory.jxplorer.JXplorer
Then it's working fine.
Now only the installer for OS X 10.8.2 needs to get working (I did it
manually) and then everything is working as it should be ;-)
Regards,
Rene
You can try this as well, although it shouldn't affect the command line
version...
