Re: [enhydra] Custom session manager

[Robert.Farrugia@xxxxxxxxx]

Hi Slobodan,

I think I solved it.  I created
a jonas-web.xml file in the WEB-INF directory with the java2 delegation
model set to false.
Thanks for your help.

Regards
Robert

Hi Slobodan, 

Is there a way to force the application class loader to ignore the commons
classes and reload the class again from a new jar file ?

Hi, 
  
Classes loaded by 'commons class loader' are not able to see your application
classes (binaries placed in 'WEB-INF'/lib). Common class loader (loads
<ENHYDRA_ROOT>/multiserver/lib/ext binaries) is a parent class loader
of application classloader (loads WEB-INF/lib binaries). Therefore, your
session home class, naturally, doesn't see your application classes.
  
Your session home (and related classes) is (basically) a part of EAF implementation
(should not be connected to your application implementation). So, my advice
is to 'split' your session home and application related implementations
- session home implementation to be loaded by common classloader and application
implementation to be loaded by application class loader.
  
The quick solution would be to place EAF (and only eaf) implementation
(together with your session home implementation) in WEB-INF/lib and get
them loaded by application class loader also (this way the same (application)
class loader will load EAF, your session home and application implementation).

Hi, 

Thanks for the reply.  I put the jar files into the <ENHYDRA_ROOT>/multiserver/lib/ext/enhydra
directory. The session home class is being found correctly.  

The problem now is occuring when loading the application.  When I
use a class (whose jar file was put in the <ENHYDRA_ROOT>/multiserver/lib/ext/enhydra
directory) and it uses classes from the application, the application classes
are throwing a ClassNotFound exception, even though the class jar file
is in the WEB-INF/lib directory.  If I use the basic session manager
(not CUSTOM) and I remove my jar files from <ENHYDRA_ROOT>/multiserver/lib/ext/enhydra,
the application works correctly, so I am assuming that the problem is somewhere
in the class loading ...

Hi, 
 
All EAF binaries are placed in '<ENHYDRA_ROOT>/multiserver/lib/ext/enhydra'
so I'm suggesting this location (not application WEB-INF/lib).
 
Note that all binaries placed in '<ENHYDRA_ROOT>/multiserver/lib/ext'
will be loaded by commons class loader (shared between all applications)
as a JOnAS-specific class loader that will load all classes required to
start the JOnAS server (all jars in subordinate directories will also be
loaded ). 
 
Hope this helps,

Hi, 

I am trying to use the CUSTOM feature of the SessionManager to load my
own SessionHome class.  I have added the class name to the conf file
under the CUSTOM subsection. 

The problem is where to put the session code jar file, since it is giving
a class not found exception.  I am currently putting it in the webapp
WEB-INF/lib directory. 
Do I need to add something to the classpath or any other setting for Jonas
? 

BTW I am using enhydra enterprise 6.0.1.  Any pointers on this issue
would be greatly appreciated. 

Regards
Robert
