For your reference my stack trace is
am wondering how this could not enlist will come even if i use only one <local-tx-datasource>
i think the exception occurs when trying to get connection from connection pool [based on following exception info]
org.jboss.util.NestedSQLException: Could not enlist in transaction on entering meta-aware object!javax.transaction.SystemException: enlistResource failed; - nested throwable: (javax.resource.ResourceException: Could not enlist in transaction on entering meta-aware object!javax.transaction.SystemException: enlistResource failed)

[IronJacamar] - Physically closing a set of connections

"Physically closing a set of connections"

Greetings all,
I am still working on my JCA and I have been presented with a new requirement that I am not sure how to handle.
As it stands now, my JCA can create connections to 1 of 8 physical servers and on any given server the connection can be associated with a given "account". I have this working by implementing a ConnectionRequestInfo class that identifies a host and account. Works great!
Now our ops people want me to provide them with a method of physically closing all of the connections to a given physical server. So I would need access to a list of connections in a pool through which I could loop looking for matching connections based on host name, then physically close each matching connection. I have looked through the spec and the Ironjacamar code and I cannot find any methods that would seem to help.
Anyone have any ideas?
Thanks in advance for any and all relevant responses!
Earnie!

Okay, I am doing something wrong. :) If I use the following code the authentication works, and it looks like it is downloading the binary package:
private static KnowledgeBase readKnowledgeBase() throws Exception {
KnowledgeAgentConfiguration aconf = KnowledgeAgentFactory.newKnowledgeAgentConfiguration();
KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent("test", aconf);
String url = "http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/defa...";
UrlResource resource = (UrlResource) ResourceFactory.newUrlResource(url);
resource.setBasicAuthentication("enabled");
resource.setUsername("guest");
resource.setPassword("guest");
kagent.applyChangeSet(resource);
return kagent.getKnowledgeBase();
}
I figured this out by sending it through the eclipse tcp/ip monitor proxy. And it looks like it is indeed getting the binary package. But I think the code is expecting a changeset, not a binary package. (Which is why I get the "ERROR drools.xml.ExtensibleXmlParser.fatalError - (null: 1, 1): Content is not allowed in prolog." - because it's expecting a changeset.xml, not the binary package.)
Which makes since as I am calling: kagent.applyChangeSet(resource);
So I think I'm almost there, I have to do something with the binary package, not try to apply it as a changeset...
