Hello,
I realize this is a shot in the dark, but it's possible that someone has run
into similar issues or have some debugging tips.
On our production servers, we are getting exception from Tomcat 5.x
java.lang.IllegalStateException: Cannot create a session after the response has
been committed at
org.apache.catalina.connector.Request.doGetSession(Request.java:2214)
The exception happens in servlet filter; it happens very rarely - maybe 10
times a day and we have relatively heavy traffic.
Before any of the actions are hit, request goes through StripesFilter and
SecurityFilter.
In security filter, I am trying to access request's session to check for the
presence of an attribute.
On rare occasion, we get this stack trace - it does not matter what the target
action is.
I do set few attributes on the request and access request.servletPath before
accessing a session.
If it might have anything to do with it, we are running on VMware, 64 bit java
1.5, tomcat 5.5.20, stripes 1.4.3 - any debugging tips would be greatly
appreciated. I am hoping, there is no way Tomcat can recycle same request
object while it's being used by another thread. We tried to run load tests
against the app servers, but could not reproduce it consistently under heavy
loads.
I can probably work around this exception, by explicitly checking
response.isCommited(), but I want to understand what in the world does anything
to it make it go in that state.
