Hi, sorry if i double topic, but i havent find any solution for this problem
I have JBoss 3.2.5 and JDK 1.4.2_12. There is no other JDK or JRE on machine.

When i access http://localhost:8080/web-console/, i receive on both forms error 500 and next exception.

What is exactly problem?
i dont think it is JRE or JDK is too old, since JDK 1.5 was not out when JBoss 3.2.5 was used.

How can this be solved?

Thanks in advance.
