session serialization problem
Summary: session serialization problem
Product: Tomcat 4
Version: 4.0 Final
Platform: Other
OS/Version: Other
Status: NEW
Severity: Normal
Priority: Other
Component: Catalina
AssignedTo: tomcat-dev@jakarta.apache.org
ReportedBy: jon@latchkey.com
After a bunch of headbanging, I *think* I may have found the problem I
have been having for a while now with regards to session serialization
within Catalina. I don't have email access right now, so I'm reporting it
here...
The problem it seems is that the order of session de-serialization is not
correct (it isn't dictated by the servlet api, so this is understandable), it
should execute something like this:
#1. serialize sessions
#2. servlet.destroy()
#3. servlet.init()
#4. de-serialize sessions
Instead, it seems to be executing like this:
#1. serialize sessions
#2. servlet.destroy()
#3. de-serialize sessions
#4. servlet.init()
Note that #1 and #2 may be reversed. I'm not sure. What I care about is
that #3 and #4 seemed to be mixed up.
The problem is that I have some static initializers that should be called for
a few classes in the servlet's init() method. However, they do not seem to
be called yet because static methods in those classes which rely on
static data are null because the static init() methods for those classes
have not yet been called by the servlet's init() method.
I hope that made sense. Remy or Craig, can you please tell me what the
current ordering is? If it is the case that the init() method is called *after*
the sessions are de-serialized, then that is the bug and that is bad for me.
thanks,
