HttpSession

[Trond Hersløv <tr...@gotogate.no>]

Hi!
What do I have to do if want to use a modified HttpSession class? Can I do
one of the following:
 
Hope I don't have to do it this way:
1) extract $CATALINA_HOME/common/lib/servlet-api.jar
2) decompile HttpSession.class --> HttpSession.java
3) make my modifications on HttpSession.java and compile -->
HttpSession.class
4) build a new servlet-api.jar containing the modified HttpSession.class
instead of the original one.
 
It would be nice if this was possible.
1) create a new class MyHttpSession which extends HttpSession
2) add my extra funcionality to MyHttpSession.
3) compile MyHttpSession --> MyHttpSession.class and putt it into
$CATALINA_HOME/common/classes
4)The big QUESTION: How do I config tomcat to use MyHttpSession.class
instead of HttpSession.
 
Thanks in advance
\trond

Trond-

HttpSession.class in servlet-api.jar is an interface as is implemented 
in several places in the Tomcat source. To add new functionality I would 
make changes to the following classes and recompile Tomcat:

-javax.servlet.http.HttpSession.java
     add your new methods:

     public void myHelperMethod();

-org.apache.catalina.session.StandardSession.java
     implement your new method:

     public void myHelperMethod()
     {
         //useful code
     }

-org.apache.catalina.session.StandardSessionFacade.java
     add the lines:

     public void myHelperMethod()
     {
         this.session.myHelperMethod();
     }

-org.apache.catalina.cluster.session.DeltaSession.java
     implement your new method:

     public void myHelperMethod()
     {
         //useful code
     }

-org.apache.catalina.cluster.session.DeltaSessionFacade.java
     add the lines:

     public void myHelperMethod()
     {
         this.session.myHelperMethod();
     }

Hope this helps!
