The launcher configures the run-time environment for J2EE application
clients and thin client applications (not J2EE application clients). The launcher
utility is located in the main entry point of the Java Network Launching Protocol
(JNLP) application client. The main class launcher name is com.ibm.websphere.client.launcher.ClientLauncher
and is located in the WebSphereClientLauncher.jar file.
The launcher tool requires that the following properties are defined.
- com.ibm.websphere.client.launcher.main
- If the client that is to be run is a thin client, then this property should
be specified. It specifies the class where the main entry point of the application
resides.
- com.ibm.websphere.client.launcher.ear
- If the client that is to run is the J2EE client, then this property should
be specified. It specifies the name of the ear file to be executed. This
property takes precedence over com.ibm.websphere.client.launcher.main although
only one of the two properties should be specified.
- com.ibm.websphere.client.launcher.classpath.* (required for J2EE client
applications only)
- There can be a set of properties that are prefixed with com.ibm.websphere.client.launcher.classpath.
Each property specifies a JAR file that is to be added to the class path of
the application. This JAR file is a JAR file that is already defined as a
resource for the application. This file is needed so that the correct elements
of the class path of the Java Virtual Machine (JVM) starting the client launcher
can be retrieved and added to the class path of the (JVM) that is to be spawned
for the application client.
These properties are not defined in a separate properties file.
Instead, they are defined as part of the Java Network Launching Protocol files.
