Application Client

This section describes known application client issues and associated solutions.

Library JAR packaged in Application Client Archive overwrites MANIFEST file (6193556)

Description

If you have a top level JAR file inside your client JAR (in this case, reporter.jar), when you deploy the client JAR, the MANIFEST file for that JAR overwrites the MANIFEST file for the client JAR.

Solution

None at this time.

ACC always tries to connect to localhost:3700 (6527987)

Description

The application client always tries to connect to localhost:3700. The problem is that several system properties need to be read before the client code is invoked.

Solution

Set the following as system properties (-D in your JAVA_CMD). Do not set them in your appclient code:

org.omg.CORBA.ORBInitialHost = server_instance_host
org.omg.CORBA.ORBInitialPort = server_instance_port

Unable to start domain , missing sunpkcs11.jar (6571044)

Description

Running on 64–bit Linux, the following exception when starting a domain. The issue is a missing sunpkcs11.jar under jdk1.5.0_11/jre/lib/ext/.

Solution

This is a known JDK bug with 64–bit Linux, and will be fixed in JDK 1.5.0_13.

ASQuickStartup breaks SocketChannel.keyFor(), returning null instead of the SelectionKey (Issue Tracker 3027)

Description

When a SocketChannel is registered on several Selectors, doing socketChannel.keyFor(lastRegisteredSelector) returns null instead of the SelectionKey.

Solution

This is related to a JDK bug, 6562829, and is expected to be fixed in 6.0 U3. A workaround has been included in Application Server 9.1, such that the selector is unwrapped before the keyFor API is called. This enables the keyFor to succeed until JDK bug is fixed.
