Deserialize tomcat sessions

Hi all,

 

 

I have Persistent sessions in tomcat that are saved into Postgresql
database. I make a Select from tomcat_sessions in order to get sessions to
get an attribute that is on each one.

 

What is the function to deserialize each session from database?

 

 

Thanks,

RE: Deserialize tomcat sessions

Posted by Abraham Fdez <ab...@fnac.es>.
Hi Filip,

In this line " StandardSession mysession = new StandardSession();" there
could be in "new StandardSession()" a Manager.

What should Manager I use?

RE: Deserialize tomcat sessions

Posted by Abraham Fdez <ab...@fnac.es>.
Thanks Filip,

But... could you help me how to do it?. Now I only have this:

Object stuff = (Object) new ObjectInputStream(new
ByteArrayInputStream(kk2.getSession_Data())).readObject();

Where kk2.getSession_Data returns a byte array (byte[]) where attributes
are.


Thanks,
