Is it normal for the internal IP address of the server to be showing up at the client? That seems to be strange. Would JNDI be providing that address? ----- Original Message ----- From: Tim Anderson To: [email protected] Sent: Sunday, January 22, 2006 5:21 AM Subject: RE: [openjms-user] Cannot connect to queue crossing Internet You don't need to set internalHost. Its only used in situations where you have clients connecting from both inside and outside the firewall. See: http://openjms.sourceforge.net/config/reference.html#TcpConfiguration From the logs, it looks like the client has sucessfully connected to the JNDI service, but has failed to create a JMS connection, possibly due to authentication problems. -Tim ---------------------------------------------------------------------------- From: openjms-user-admin-5NWGOfrQmneRv+LV9MX5uipxlwaOVQ5f@public.gmane.org [mailto:openjms-user-admin-5NWGOfrQmneRv+LV9MX5uipxlwaOVQ5f@public.gmane.org] On Behalf Of Wayne Iriwn Sent: Sunday, 22 January 2006 2:07 PM To: [email protected] Subject: [openjms-user] Cannot connect to queue crossing Internet I am trying to put together a JMS protoype system to test JMS communications. I am using openjms-0.7.7-alpha-3 on Sun Java 1.5.0_06-b05. I have a remote client behind a firewall/router that I am trying to send a message to a queue on a server behind a firewalled router. This should be a standard arrangement. The client is basically running the Sender example. I have configured the jndi.properties file on the client to point to the servers router IP address and port 1234. I have setup port forwarding on the servers router 1234 port to the servers IP address and port 1234. I have configured the openjms.xml file as follows <?xml version="1.0"?> <!-- Definitions at http://openjms.sourceforge.net/config/reference.html#ConnectionFactories --> <Configuration> <DatabaseConfiguration> <!-- Info at http://dev.mysql.com/doc/refman/5.1/en/cj-configuration-properties.html --> <RdbmsDatabaseConfiguration driver="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost:3306/jmsdb" user="xxxx" password="xxxxxxx" maxActive="10" maxIdle="10" /> </DatabaseConfiguration> <AdminConfiguration script="${openjms.home}\bin\startup.bat" /> <ServerConfiguration host="124.76.253.69" embeddedJNDI="true" /> <Connectors> <Connector scheme="tcp"> <ConnectionFactories> <ConnectionFactory name="ConnectionFactory" /> <QueueConnectionFactory name="JmsQueueConnectionFactory" /> <TopicConnectionFactory name="JmsTopicConnectionFactory" /> </ConnectionFactories> </Connector> <TcpConfiguration internalHost="localhost" port="1234" jndiPort="1234" adminPort="1234" bindAll="true" /> </Configuration> When I run the test, it does not work. The client end reports java.net.ConnectionException: javax.jms.JMSException: Failed to connect to 192.168.62.50:1234 The server log looks like 20:58:53.150 INFO [main] - Creating RdbmsAdapter for com.mysql.jdbc.Driver 20:58:53.861 INFO [main] -

Cleaning up resources 20:59:53.877 DEBUG [EventManager-Worker-0] - GC Threshold=517720 Free=755408 I have tested this successfully inside the a LAN, but when I try to cross the Internet, it fails. Is seems so close to conencting. The biggest anomaloy is that the client is reporting it cannot connect to the IP address 192.168.62.50, which is the DHSCP address of my server inside the router. I don't believe that the client should every be seeing the internal IP address. Is this a bug in OpenJMS or a miss configuration on my behalf. Anyone got any suggestions?
