Hello guys,
there is a bug in JCAConnectionFactory undeployment (I guess in all
3.0 branches). Here are the details (I played with MySQL). When it is created the
J2EEManagedObject is created with a name like:
J2EEServer=Local,JCAResource=JCA,j2eeType=JCAConnectionFactory,name=MySqlDS-LocalTxCM
But when it is undeployed, this object isn't removed and remains
registered. Thus redeployment will fail.
The JCAConnectionFactory.destroy() method searches with criteria:
J2EEManagedObject.getDomainName() + ":" +
J2EEManagedObject.TYPE + "=" + JCAConnectionFactory.J2EE_TYPE + "," +
"name=" + pName + "," +
"*"
which results in
jboss.management.local:j2eeType=JCAConnectionFactory,name=MySqlDS-LocalTxCM,*
Id it correct? I am still not good at it but it doesn't work.
I changed the criteria to:
ObjectName lServer = null;
try {
lServer = (ObjectName) pServer.queryNames(
new ObjectName(
J2EEManagedObject.getDomainName() + ":" +
J2EEManagedObject.TYPE + "=" + J2EEServer.J2EE_TYPE + "," +
"*"
),
null
).iterator().next();
}
catch( Exception e ) {
lLog.error( "Could not locate JSR-77 Server: " + pName, e );
}
ObjectName lJCAResource = null;
try {
// Check if the JCA Resource exists and if not create one
Set lNames = pServer.queryNames(
new ObjectName(
J2EEManagedObject.getDomainName() + ":" +
J2EEManagedObject.TYPE + "=" + JCAResource.J2EE_TYPE + "," +
"*"
),
null
);
if( lNames.isEmpty() ) {
// Now create the JCA resource
lJCAResource = JCAResource.create( pServer, "JCA" );
} else {
lJCAResource = (ObjectName) lNames.iterator().next();
}
}
catch( Exception e ) {
lLog.error( "Could not create JSR-77 JCA resource", e );
}
String searchCriteria =
J2EEManagedObject.getDomainName() + ":" +
J2EEServer.J2EE_TYPE + "=" +
lServer.getKeyProperty( "name" ) + "," +
JCAResource.J2EE_TYPE + "=" +
lJCAResource.getKeyProperty( "name" ) + "," +
J2EEManagedObject.TYPE + "=" + JCAConnectionFactory.J2EE_TYPE + "," +
"name=" + pName + "," +
"*";
This criteria is:
J2EEServer=Local,JCAResource=JCA,j2eeType=JCAConnectionFactory,name=MySqlDS-LocalTxCM,*
And it works. I guess it's a weird way. Please, comment it.
TIA!
