Jboss 4.2-G.A fails to build from source

[mtedone1]

This is the error I got:

[drive]:\server\src\main\org\jboss\ejb\plugins\cmp\jdbc\ByteArrayBlob.java:46: org.jboss.ejb.plugins.cmp.jdbc.ByteArrayBlob is not abstract and does not override abstract method getBinaryStream(long,long) in java.sql.Blob
public final class ByteArrayBlob implements Blob

What version of the JDK are you using? I am guessing 6. Try compiling it with 1.5 (6 is not yet qualified).

[mtedone1]

Yes, I'm using 6

Try compiling it with 1.5

That is the key. Pay atention if you using Ubuntu 10.10, that there is symlink structure in /etc/alternatives which forces you to use Open JDK 6. Symlinks wasn't been removed even if I run sudo apt-get remove java-6-openjdk..
