Hi there,
we have an appclient which communication to an appserver. The configuration for the communication is in a property file which is used for initialize the initialcontext.
No we have the task to support multiple appserver. This means, if the appserver1 is down we have to switch to appserver2. This should not be done by extends the jndi url.
If I test the mechanism I get following exception:
Caused by: javax.naming.CommunicationException: Can't find SerialContextProvider [Root exception is org.omg.CORBA.COMM_FAILURE: vmcid: SUN minor code: 201 completed: No]

The reason for the exception is the wrong configured hostname.
In the second try I get following exception:
Caused by: javax.naming.CommunicationException: serial context communication ex [Root exception is com.sun.enterprise.connectors.ConnectorRuntimeException: Failed to look up ConnectorDescriptor from JNDI]

I don't understand the reason for this exception. Between the exceptions I close the old InitialContext and create a new InitialContext.
InitialContext - Parameters:
org.omg.CORBA.ORBInitialHost = wronghost
org.omg.CORBA.ORBInitialPort = 3700
java.naming.factory.initial = com.sun.enterprise.naming.SerialInitContextFactory
java.naming.factory.url.pkgs = com.sun.enterprise.naming
java.naming.factory.state = com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl
org.omg.CORBA.ORBInitialHost = correcthost
If I try with the correct hostname, everything works fine.
Has someone an idea?
Is it not possible to initialize a second InitialContext with different parameters?
Thanks...
Bernd
