I am trying to set up the cache invalidation service using the
JMSCacheInvalidationBridge. I particularly want to juse the JMS invalidation bridge,
because I want to be able to invalidate entity beans from Java Stored Procedures
running in Oracle.
Note: I am runing JBoss in the 'all' configuration.
I bought the "JBoss AS Clustering" documentation from the JBoss website and faithfully
followed the instructions in Chapter 8. This mainly means uncommenting the mbean
section in cache-invalidation-service.xml.
Although it is not documented, I have worked out that you need to comment out the
JGCacheInvalidationBridge mbean section in cluster-service.xml if you are using the
JMS one in cache-invalidation-service.xml.
Having done this however, I still get an Exception in server.log during startup:
ERROR [org.jboss.naming.NamingService] Could not start on port 1099
java.net.BindException: Address already in use: JVM_Bind
at java.net.PlainSocketImpl.socketBind(Native Method)
...
At one point I did reinstall JBoss from the original distribution. Before that I was
getting a similar error but the port was 1100. I think the only difference is the
order that the services were getting loaded in.
The most likely references to NamingService's I could find were in
all/conf/jboss-service.xml and all/deploy/cluster-service.xml. The on one in
cluster-service.xml is the HANamingService.
Both of these services have "Port" attributes, which are set to 1099 in the former
case and 1100 in the latter, so in theory there should be no clash.
I can get rid of the Exception by setting the Port attribute in jboss-service.xml to
-1, but I get errors further down the line from services that depend on this service.
The only service that has been added as far as I can see is the JMS cache invalidation
service. The only reference to a port number in cache-invalidation-service.xml is the
atttribute ProviderUrl which is in reference to other nodes in a cluster.
Is it possible this bridge is locking up port 1099?
The otther odd thing is that I can't telnet to port 1099 once the server has started.
So although it reports a BindException, it doesn't look like port 1099 actually gets
used by anything.
Confused
