  Subject: [openjms-user] My OpenJMS(0.7.3.1) suddenly crashed


  Hi all,

  My OpenJMS(0.7.3.1) suddenly crashed and I give the following message from
my
  program which is used to send message to OpenJMS Server.


============================================================================
===
  Could not create JNDI API context: javax.naming.NamingException:
  Connection refused to host: localhost; nested exception is:
   java.net.ConnectException: A remote host refused an attempted connect
operation.
   [Root exception is java.rmi.ConnectException:
    Connection refused to host: localhost; nested exception is:
    java.net.ConnectException: A remote host refused an attempted connect
operation.]

============================================================================

  [1] Do you know what is the happen? I cannot find any useful information
in openjms.log.
  How can I trace that?
  [tima] Easiest way is to configure log4j to log debug messages i.e, change
log4j.xml:

    <category name="exolab">
      <priority value="DEBUG" />
      <appender-ref ref="STDOUT" />
      <appender-ref ref="openjms" />
    </category>


  [2] Actually, my program is using rmi to connect with Openjms. Is it not
stable? Should I use
  tcp or http? Are they more stable?
  [tima] rmi is stable in 0.7.3.1. tcp and http were not. All connectors
should be stable in 0.7.5.

  [3] Besides, I wanna test the connecting server using http, so I start the
OpenJms using this
  way:
  ./startjms.sh -config ../config/http_jms.xml
  However, it only works for "tcp://localhost:3035/", but fails in
  "http://localhost:8080/openjms/servlet/OpenJMSJndi". I check the port of
8080 using
  netstat. It seems that 8080 is not listening.

  [tima] You need to deploy the openjms.war file in tomcat in order to use
the http connector.


  [4] Morever, can OpenJMS(0.7.3.1) support rmi and http at the same time?
Which configuation
  file can I use for starting the server.
  [tima] Multiple connectors are only supported from 0.7.5 updwards.

  [5] Last but not least, I find that the size of file called openjms.db is
growing. If this
  is a temp file for storing queue message, the file size should be drop
after no message in
  JMS Server. Why does it only grow?

  [tima] The openjms.db file is the database file used by the JDBM, which
            was only intended for demonstration purposes. I would encourage
you
            to use an RDBMS such as MySQL instead.



  Would you please help me to solve the problem. Thx a lot!!

  Eric
