Thank you rathorev for your contribution.
I tried to do like you describe, but... I got the same ERROR.
But, you gave me an idea.
I did a copy of the files contained in the JBossIDE (axis 1.2):
/usr/local/eclipse/plugins/org.jboss.ide.eclipse.jdt.ws.core_1.5.1.GA/lib/axis-1.2/
to the directory JBOSSHOME/client.
BINGO!!!!! It worked for me.
