Hello,

The code bellow works fine on Windows tomcat but doesn't on Linux.
I recompiled it. Could you give me any idea why it is so?
It thrown null pointer exception on if line.
I know that before calling dbconn.getConnection() i should check wheather is
dbconn != null.
If it is because of Tomcats settings where and what should i change to make
it work?

thx,
Kanar

DBConnection dbconn=(DBConnection)session.getAttribute("dbconn");
if(dbconn.getConnection() != null){//session didn't expired
....
}
