java problems

[Urza9814]

I recently had to reinstall Mandriva 2007 after it was completely formatted. Anyways, I'm trying to get Freenet running again, but I'm getting the following error, and their own support mailing list is no help at all.

 

[root@localhost freenet]# sh start-freenet.sh
Detected freenet-ext.jar

Starting Freenet now: Command line: java -Xmx128m -XX:MaxDirectMemorySize=128m freenet.node.Main

I've tried a few different versions of Java, but they all give the same error, and when I try just removing that argument, it won't start at all. Anyone know what's going on?

It looks like a custom option which means you probably have to use a very specific JVM... Having said that - I would have thought their support would have told you that if it were true...

 

I'm pretty sure (although not certain - it's only from memory) that -XX:MaxDirectMemorySize is not a standard option - hence the error message. You would need a JVM that's expecting this option...

I dunno. I did of course google it, and found a few pages referring to it.

For example:

http://forum.java.sun.com/thread.jspa?thre...ssageID=3506934

http://www.nabble.com/OutOfMemory-Exception-t3638970.html

http://mina.apache.org/faq.html#FAQ-Iget%2...tunderheavyload.

 

none of those seem to refer to a specific JVM being needed.....

 

...oh. damn. I just noticed under the 'version' info of Java, it's not actually Java. It's running 'JamVM'. Even though I ran the Java installer, like, 5 times with different versions and such. wtf. Oh well, let's try it with first removing this damn JamVM thing.

 

edit:

Ok, it won't let me remove JamVM, and I can't figure out where java is supposed to go and how to get it there, but I replaced the line in the script with the full path of the real java binary, and it appears to be working. But any help fully replacing this JamVM thing would be appreciated.
