for the folowing line in a jsp

net.advinfo.pcs.pcscontroller.pspsetup.standards.LanguageObjectTypeAndChklstCatBean is in WEB-INF\classes\net\advinfo\pcs\pcscontroller\pspsetup\standards\
Here is my server info
Server Information
Tomcat Version JVM Version JVM Vendor OS Name OS Version OS Architecture
Apache Tomcat/5.0.18 1.4.2_03-b02 Sun Microsystems Inc. Windows XP 5.1 x86
The intersting thing is when I access the same JSP again I'm not getting this error. This error happens randomly when the page is accessed for the first time after the application is deployed. The same page works fine in tomcat 4.x.
Please let me know the solution if any.
Thanks,

RE: problem in
Posted by Yansheng Lin <ya...@silvacom.com>.
Hey I am not exactly sure what happens here, I don't use jsp tags often
nowadays. But I will take a stab. Because you specify the scope of the
JavaBean to be session scope, the JSP engine will skip the body of <jsp:useBean>
tag if the bean object is already in the session. You said the subsequent
request to the page results no error, maybe by that time the cached session(from
previous deployment) was invalidated finally. I wonder if things would be
different when you use a different scope.
no? anyone?
