Re: [Carbon-dev] Can't send/receive JMS Object Messages to/from Qpid broker from Carbon Environment.

[Sanjiva Weerawarana]

Azeez can you organize a brainstorm session on this issue next week? I'm
assuming release pressure will be off by then but if not lets wait until
after the release. This is something we need to discuss and come up with a
proper solution.

Sanjiva.

Re: [Carbon-dev] Can't send/receive JMS Object Messages to/from Qpid broker from Carbon Environment.

[Afkham Azeez]

Also within another appserver, HTTP session replication will not work even
in this model.

 Hi ,

 In the ESB Message Store we have an option where users can point to any
 JMS broker as the underlying message storage. Here we store the Message
as a
 serializable Object Message.
 Problem is when i try to connect to a Qpid broker using our qpid client
 libs in the Carbon environment it gives a Class not found Error when we
try
 to de serialize the message back to the Original format.

 Here the problem is at the point where it de serialize the message. The
 the serializable object type we used is not visible to that class
loader.
 I tried using the ActiveMQ broker with its client libs. but did not
face
 this issue.

 We need to solve this Problem and this a blocker. One possible work
 around i can think of is change the way i serialize the message to use
JMS
 TextMessages instead and use Message headers to keep the context
 information. That will resolve issue i m facing.

 But we mush fix this in a proper way to support sending JMSObject
 messages from the Carbon Environment since otherwise it implies that
 we can't filly utilize the functionality of our Message broker inside
the
 carbon Environment.

 Help or directions for resolving this is highly appreciated.

 thanks,
 Charith

Re: [Carbon-dev] Can't send/receive JMS Object Messages to/from Qpid broker from Carbon Environment.

[Afkham Azeez]

That is also tricky because the carbon webapp is deployed inside one tomcat
& other webapps are deployed within another tomcat. Handling the carbon
request dispatching has to be handled in different way in standlone & webapp
modes in that case.

I thought we discussed an option where we ran EVERYTHING through OSGi but
still deployed in Tomcat. So in that case we would deploy webapps inside
Tomcat running inside Carbon running inside Tomcat.

Re: [Carbon-dev] Can't send/receive JMS Object Messages to/from Qpid broker from Carbon Environment.

[Charith Wickramarachchi]

This is Fixed by Introducing a Class loading aware Object input stream
implementation at the qpid clients.
I try to commit the changes but couldn't due to the branching process.

Created a issue [1] and attach the patch.

Dhanushka please review and commit this patch.

Re: [Carbon-dev] Can't send/receive JMS Object Messages to/from Qpid broker from Carbon Environment.

Also the class-loading issues in JMS transport and this particular issue
that Charith is having are results of that.

Re: [Carbon-dev] Can't send/receive JMS Object Messages to/from Qpid broker from Carbon Environment.

[Afkham Azeez]

Of course we can go for a very clean OSGi based solution if we drop supports
for Carbon webapp deployment support. We have major limitations because of
this. Even HTTP session replication cannot be done because the classes
placed into the HTTP session in the OSGi container are not visible to
Tomcat.

Re: [Carbon-dev] Can't send/receive JMS Object Messages to/from Qpid broker from Carbon Environment.

[Sameera Jayasoma]

Again, this happens due to duplication qpid jars inside the
$CARBON_HOME/repository/components/plugins and $CARBON_HOME/lib folder. We
had a look at this issue couple of times, but unable to find a proper
solution.

The deserialized Object is loaded inside the OSGi environment, but the
deserialization happens inside the system app classloader space. Hence the
Class is not visible.

One option is to put the classes to the lib folder. But thats ugly.

Thanks,
Sameera

And make sure that ObjectMessage holds a Serializable type that is defined

I should look at the ESB Message Store right?

Its an Internal Serializable class named JMSPersistentMessage which holds
the persistent format of the message. And its the Object type that we set in
the jms ObjectMessage

[Carbon-dev] Can't send/receive JMS Object Messages to/from Qpid broker from Carbon Environment.

[Charith Wickramarachchi]

Hi ,

In the ESB Message Store we have an option where users can point to any JMS
broker as the underlying message storage. Here we store the Message as a
serializable Object Message.
Problem is when i try to connect to a Qpid broker using our qpid client libs
in the Carbon environment  it gives a Class not found Error when we try to
de serialize the message back to the Original format.

Here the problem is at the point where it de serialize the message. The the
serializable object type we used is not visible to that class loader.
I tried using the ActiveMQ broker with its client libs. but did not face
this issue.

We need to solve this Problem and this a blocker. One possible work around i
can think of is change the way i serialize the message to use JMS
TextMessages instead and use Message headers to keep the context
information. That will resolve issue i m facing.

But we mush fix this in a proper way to support sending JMSObject messages
from the Carbon Environment since otherwise it implies that
we can't filly utilize the functionality of our Message broker inside the
carbon Environment.

Help or directions for resolving this is highly appreciated.

thanks,
Charith
