connecting not with localhost, but with real IP name

[chrjacob]

Hi there,

I've got the following problem: I want to call me session bean remotely. During development time, I have no problems in looking up the bean with the URL "jnp://localhost:1099". But, if I used the real IP name of my PC, I get the following exception:

javax.naming.CommunicationException: Could not obtain connection to any of these urls: c003a9521:1099 and discovery failed with error: javax.naming.CommunicationException: Receive timed out [Root exception is java.net.SocketTimeoutException: Receive timed out] [Root exception is javax.naming.CommunicationException: Failed to connect to server c003a9521:1099 [Root exception is javax.naming.ServiceUnavailableException: Failed to connect to server c003a9521:1099 [Root exception is java.net.ConnectException: Connection refused: connect]]]

Does anyone have a clue what went wrong?

TIA, Christian

Which version of JBoss do you use and how do you start JBoss? Do you use -b option to start JBoss? See this for details http://wiki.jboss.org/wiki/Wiki.jsp?page=JBoss42FAQ

Hi Jaikiran,

I use JBoss 4.2.2.GA . To start it with the option -b 0.0.0.0 really helped. Many thanks for your help!

Kind regards,
Christian
