Hi,
I am using Tomcat 404 and OC4J on Windows .
When I send approximately 25 requests, very often tomcat returns the
following error :
HTTP/1.1 500 Internal Server Error
Content-Type: text/html;charset=ISO-8859-1
Connection: close
Connection: close
<html><head><title>Apache Tomcat/4.0.4 - Error
report</title><STYLE><!--H1{font-family : sans-serif,Arial,Tahoma;color :
white;background-color : #0086b2;} BODY{font-family :
sans-serif,Arial,Tahoma;color : black;background-color : white;} B{color :
white;background-color : #0086b2;} HR{color : #0086b2;} --></STYLE>
</head><body><h1>Apache Tomcat/4.0.4 - HTTP Status 500 - Internal Server
Error</h1><HR size="1" noshade><p><b>type</b> Exception
report</p><p><b>message</b> <u>Internal Server
Error</u></p><p><b>description</b> <u>The server encountered an internal
error (Internal Server Error) that prevented it from fulfilling this
request.</u></p><p><b>exception</b> <pre>java.lang.IllegalStateException:
getAttribute: Session already invalidated at
org.apache.catalina.session.StandardSession.getAttribute(StandardSession.jav
a:900) at
org.apache.catalina.session.StandardSessionFacade.getAttribute(StandardSessi
onFacade.java:171) at
org.apache.catalina.session.StandardSessionFacade.getAttribute(StandardSessi
onFacade.java:17
Now the HTTP request is very simple, the requests call a single JSP page
which in turn calls taglibs, which in turn calls EJBs to retrieve data from
database and then return the HTML to the client. I have narrowed down the
problem on to Tomcat / my code running on Tomcat. However, my problem I am
not able to figure out, where the problem is ? I have checked mail archives
on this list, but haven't really found out any real pointers yet ....
Any help/pointers on this highly appreciated....
Many Thanks,
Tejas
