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 WebSphere Application Server product.
You can install an application, enterprise bean (EJB) module, or Web module developed for a Version 5.x product on a 5.x or 6.x deployment target, provided the module:
If the module supports J2EE 1.4, calls a 6.x API or uses a 6.x feature, then you must install the module on a 6.x deployment target.
Selecting options such as Precompile JavaServer Pages files, Use binary configuration, Deploy Web services or Deploy enterprise beans during application installation indicates that the application uses 6.0.x product features. You cannot deploy such applications on a 5.x deployment target. You must deploy such applications on a 6.x deployment target.
Similarly, you must deploy an application that uses J2EE 1.4 features such as Java Authorization Contract for Containers (JACC) provided by an application server on a 6.x deployment target.
You can install a standalone resource adapter (connector) module, or 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 you must install the module on a 6.x deployment target.
A 5.x deployment target is a server or a cluster with at least one member on a WebSphere Application Server Version 5 product.
A 6.x deployment target is a server or cluster with all members on a WebSphere Application Server Version 6 product.
