Thanks so much Peter. I will try this solution.
I discovered iside tomcat logs a problem with libtcnative-1 that result be an oldest version of library, that i have installed from debian repository ( see this link )
Hi People, after a long series of experiments, i solved the issue.
My configuratione was Debian Lenny, Apache2 , Tomcat6 and JBoss.
During the programs installation i have used only Stable Debian package via "apt-get install" including "libtcnative-1".
Certainly the version of tomcat native client was oldest....and incompatible with JBoss....
I have seen in tomcat logs that there were some GRAVE or SEVERE error relativly this component.
I have tried to install the new APR at version 1.4, but with other operation i have corrupted libc6 and it was impossibile to install build-essential to compile source code. So i have took hard decision, redo all server. But i chose to only install programs from binary or source code.
Now the server starts perfectly!
Then i suppuse that the problem was only libtcnative-1 and other default apache configuration.
When will ended all configuration , i will post other suggestions!
D E, thank you for posting how you solved the problem!
I'll add your experiences to the list of reasons why I recommend that one should never use the distro package manager to install anything Java related.
