Hello,
While migrating from a web-server application to a J2EE application with
JBoss, I run into some problems. The original version was already working on
Tomcat and now I wanted to add the JBoss functionality. I am using
Connection polling with Oracle through JNDI which seems to work fine. But
when I open and close a connection on this pool, directly after that Tomcat
wont load any pages anymore (not even html), and I get the next Exception:
java.lang.NullPointerExceptionnull at
org.apache.tomcat.util.FileUtil.patch(FileUtil.java:271)null at
org.apache.tomcat.util.FileUtil.safePath(FileUtil.java:180)null at

So the exception occurs somewhere in Tomcat (?) after a connectionpool is
being used for the first time. Anybody got an idea what's wrong here?
Rien.
