connect to a remote jboss
Hello,
I have problems when i try to access remote connection factory using a managed connection pool although i followed the FAQ posted by Adrian.
Question:
How do I access a remote jboss connection factory using a managed connection pool.
Sympton:
The message is always sent to the local testQueue. But it is expected that the message was sent to the remote testQueue.
Testing Enviroment:
(1)Two jboss-3.2.2 servers are runing. One is runing on workstation(is called remote server), the other is runing on notebook(my local server).
(2)Both runing on redhat 9.0.
(3)/etc/hosts file are set properly in both machine. The $hostname returns the name which maps to non-loop ip address.
(4)In both jboss servers, testQueue is preconfigued (coming with the installation).
(5)Testing program: I modified the EchoBean.java from src/main/org/jboss/chap7/ext1. In this testing case, there are six files:
(a)EchoBean.java
(b)Echo.java
(c)EchoHome.java
(d)ExClient.java
(e)ejb-jar.xml
(f)jboss.xml
I ran the example client (ExClient) on my notebook against the Echo Bean(deployed in my notebook also) which accesses a remote jboss connection factory (workstation) using a managed connection pool. It is expected that the EchoBean will send the message from the client into remote queue.
I followed the FAQ posted by adrain (in my notebook server):
(1)deploy the provider for the remote machine (workstation).
I did this by adding one definition into jms/jms-ds.xml file in local server (notebook) as following (NOTE:172.16.100.103 is remote server ip – workstation):
RemoteJMSProvider
jnp://172.16.100.103:1099
org.jboss.jms.jndi.JBossMQProvider
UIL2XAConnectionFactory
UIL2XAConnectionFactory
(2)deploy the managed connection factory using this provider:
I did this by adding <tx-connection-factory> in jms-ds.xml file:
<tx-connection-factory>
<jndi-name>RemoteJmsXA</jndi-name>
<xa-transaction/>
<adapter-display-name>JMS Adapter</adapter-display-name>
<config-property name="SessionDefaultType" type="java.lang.String">javax.jms.Topic</config-property>
<config-property name="JmsProviderAdapterJNDI" type="java.lang.String">java:/RemoteJMSProvider</config-property>
<security-domain-and-application>RemoteJmsXARealm</security-domain-and-application>
</tx-connection-factory>
(3)Finally, configued the user/password in conf/login-config.xml.
<application-policy name = "RemoteJmsXARealm">
<login-module code = "org.jboss.resource.security.ConfiguredIdentityLoginModule"
flag = "required">
<module-option name = "principal">guest</module-option>
<module-option name = "userName">guest</module-option>
<module-option name = "password">guest</module-option>
<module-option name = "managedConnectionFactoryName">jboss.jca:service=TxCM,name=RemoteJmsXA</module-option>
</login-module>
</application-policy>
