You can update application files deployed on a server. Update your J2EE application or modules and reassemble them using an assembly tool. Typical tasks include adding or editing assembly properties, adding or importing modules into an application, and adding enterprise beans, Web components, and files.
Also, determine whether the updated files can be installed to your deployment targets. WebSphere Application Server Version 6.x supports J2EE 1.4 enterprise applications and modules.
If you are deploying J2EE 1.4 modules, ensure that the deployment target and its node support Version 6.x. You can deploy J2EE 1.4 modules to V6.x servers or to clusters that contain V6.x cluster members only. You cannot deploy J2EE 1.4 modules to servers on V5.x nodes or to clusters that contain Version 5.x cluster members.
The administrative console Server collection pages show the versions for deployment targets.
In some situations, you can update applications or modules without restarting the application server using hot deployment. Do not use hot deployment unless you are an experienced user and are updating applications in a development or test environment.
When saving the configuration, synchronize the configuration with the nodes where the application is expected to run.
Next, test the application. For
example, point a Web browser at the URL for a deployed application (typically http://hostname:9060/Web_module_name,
where hostname is your valid Web server and 9060 is the default port
number) and examine the performance of the application. If the application
does not perform as desired, edit
the application configuration, then save and test it again.
