Please, i need help. I have been searching how to solve this problem, but i couldn't find anything.

I have installed Java 6 x32, but i'm getting the same error.

I've also tried the x64 version (of the emulator and Java too), but is just the same. :S

If you need more information about my computer or something, please tell me.

I hope someone could help me.

Which JPCSP version are you using? Can get latest one here:
http://buildbot.orphis.net/jpcsp/

[javitoXIII]

I was using version 2832. Now i downloaded version 2838 (latest one), but it shows the same error, both x32 and x64 versions.

[montcer9012]

That error is related to Java; are you sure you download Java client? There's other threads with similar issue and those where solved by downloading the Java client instead the JSD.

[javitoXIII]

I had downloaded Java 6 x86 from this page:

http://www.java.com/en/download/manual_v6.jsp

That's the version i have installed. Is that the Java client? (I don't know to much about this.)

[nash67]

you should use java 7 update 9
http://www.java.com/en/download/manual.jsp

[javitoXIII]

I've installed it before version 6, but it gives me the same error.

Now it's working!!!

I've searched in the forum [log4j.dtd], and i found this post:

http://www.emunewz.net/forum/showthread.php?tid=5914

I've done what says in it and it worked! And now, let's play. XD

Thanks for your help!
