Application modules

The contents of a module affect whether you can install the module on a deployment target. A deployment target is a server or a cluster with at least one member on a WAS product.
You can install...

Support J2EE 1.4
Call any 6.x runtime APIs
Use any 6.x product features

Modules that support J2EE 1.4 can be installed on 6.x deployment targets.
Modules that call a 6.1.x API or use a 6.1.x feature can be installed on 6.1.x deployment targets.
Modules that call a 6.0.x API or use a 6.0.x feature can be installed on a 6.0.x or 6.1.x deployment targets.
Selecting options such as...

Precompile JavaServer Pages files
Use binary configuration
Deploy Web services
Deploy enterprise beans during application installation

...indicates that the application uses 6.1.x product features.
For applications that use J2EE 1.4 features such as JACC use 6.x deployment targets.

RAR files

You can install a standalone RAR file, developed for a Version 5.x product to a 5.x or 6.x deployment target, provided the module does not call any 6.x runtime APIs. If the module calls a 6.x API, then install the module on a 6.x deployment target.

Deployment targets

A 5.x deployment target is a server or a cluster with at least one member on a WAS V5 product. A 6.x deployment target is a server or cluster with all members on a WAS V6 product.
