Try a different approach - What's wrong with catalina.session???

Greetings!

Let's try this again. From the error message below, it would appear
that there is something WRONG with
"org.apache.catalina.session.StandardSession". Note from the error that
we get a "java.lang.NoSuchMethodError" - the method does not exist.

After reading the Catalina Javadocs, it becomes aparent there are two
StandardSessionFacade constructors. One is:

StandardSessionFacade(javax.servlet.http.HttpSession session);
the other is
StandardSessionFacade(org.apache.catalina.session.StandardSession
session)

It would appear that the catalina session version is getting called by
default, because I ask for no specific one in my code. The problem is
that there is NO "StandardSession" class, according to the javadocs - or
if there is (undocumented), it is missing the "putSession" method, as
stated in the error.

I think this is a BUG in Catalina. Why call one particular constructor
by default, which does not use the standard javax classes, and then NOT
supply all the required session methods? NOTE - this constructor is
called OUTSIDE my code by other Catalina code - I have no real control
over which constructor is used.

Does anyone in the developmer community know of a workaround?

Hmmm....

the difference between these two constructors is, that the one which takes a
StandardSession upcasts it to HttpSession before assigning it to it's
session attribute,
this should not cause this problem, as StandardSession does implement all
HttpSession methods (otherwise the compiler would want to have it declared
abstract).

>From my (I confess very distant) position it looks like a jvm on W2K
problem. Especially because you say it does work on Solaris.

Hi!

What is the putSession() method of a HttpSession?
Do you mean putValue?
First, this is a deprecated method, but second, StandardSession implements
that method anyway.
StandardSession is org.apache.catalina.session.StandardSession, and
implements HttpSession, which is an interface and as such not
instantiateable.

The exception points to another reason, but I can't tell without knowing
what exact version of Tomcat you use and what you pass in.

Working fine now . .

Posted by Michael Armstrong <ma...@austin.rr.com>.

    Thanks for all your help.  Tomcat 4.0 seems to be working fine now.  On
to more coding . . .

    Well, crap!  My problem was my own stupid coding oversite: incorrect
assignement statements in my autoexec.bat file.

This kind of problem indicates that your Tomcat installation is somehow
corrupted.  If it were really a bug, it would be happening to everyone,
not just to you.

I suggest that you do the following:

* Make sure you do not have anything in $JAVA_HOME/jre/lib/ext
  (most *especially* not things like servlet.jar or j2ee.jar,
  which are *guaranteed* to cause nothing but grief)

* Do a clean installation of Tomcat 4 into a new directory.

* Make sure that all the examples work (including the ones that
  use sessions)

* Install your applications and test.
