Running Solr on VPS problems

I have a VPS with Ubuntu OS.

I run solr om my local machine (windows xp laptop) just fine.

I have configured Jetty, and Solr just the same way as on my computer, but on the server.

I have also downloaded the JRE and installed it on the server.

However, whenever I try to run the start.jar file, the PuTTY terminal shows a bunch of text but gets stuck. I could pase the text here but it is very long, so unless somebody wants to see it I wont.

Also, I cant view the solr admin page at all.

Does anybody have experience in this kind of problem?

Maybe java isn't correctly installed? It is a VPS so maybe installation is different.

Thanks

UPDATE:

These are the last lines from the terminal, in other words, this is where it stops every time:

have you checked to see if a firewall is running? also, use netstat to see if there is a listener on port 8080 or whatever you have jetty assigned to.
