Message Driven Bean as JMS listener
-----------------------------------
Key: AXIS2-1069
URL: http://issues.apache.org/jira/browse/AXIS2-1069
Project: Apache Axis 2.0 (Axis2)
Issue Type: New Feature
Components: transports
Reporter: Ali Sadik Kumlali
Attachments: AxisMdb.java
I've been walking around mdb implementation for Axis2 for a while. And at last,
I've successfully served my services through it. But there are many concerns
that need to be taken into account when it comes to J2EE environment.
My purpose for creating this issue is sharing my mdb code and starting a
discussion around:
- Application server agnostic packaging and deployment model
- Necessity of listener manager integration
- Supporting JMS 1.0.2b as well
- TODO comments I've put into the mdb file
Let me list my way I've come through:
- Chose "njms" as base implementation.
- Used geronimo-spec-ejb-2.1-rc4.jar to be able to compile MDB code
- Mixed some code from AxisServlet, JMSListener, JMSMessageReceiver,
JMSConnectionFactory and put them into AxisMdb.
- Used WL8.1 which support JMS 1.0.2b API. But "njms" requires JMS 1.1.
- Used Sonic 7.0's client jars as JMS API 1.1 implementation and overrided WL's
client by putting them in system classpath
- Put all the jars come with Axis2 under APP-INF/lib folder found in ear file.
Please note that *this is WL specific* solution. Otherwise, I needed to add all
the jars into system classpath. But, in that case, I got operating system error
that complained about size of the CLASSPATH variable.
- Created an ear as following structure:
- APP-INF
- lib
- META-INF
- ejb-module.jar
- org/apache/axis2/transport/njms/AxisMdb.class
- Instead of giving absolute path for repository in the code, I only used
directory name (server_repo) and created the directory under
"C:\bea\user_projects\domains\testserver\ ". This is the folder WL's starting
and stopping scripts reside. When Axis2 is initializing, this folder found
successfully.
Since I don't know all the details of Axis2, need to be directed towards a
better code. I hope someone will look into the file I'll attach and give
feedback.
