sapnetweaver platform is the integration of the java and abap.then what is the role of java in that netweaver platform

Java makes Sap NetWeaver more powerfull than it was before.

One of the new additions to the Java functionality of NetWeaver includes the Java Virtual Machine container technology. This will allow standard Java code to run on a framework around the Java Virtual Machine itself. It does this by reducing the number of parallel users per virtual machine. It also improves on the overall memory consumption, the application stability and the number of affected users in the event of a screen freeze, loss of data or the need for re-keying of information.

The JVM technology also includes several added features designed to assist developers in managing error resolutions. This includes the ability for developers to switch a user process in the production system in or out of debugging mode on the fly allowing for minimum downtime. While also including tracing and monitoring tools for error analysis and hopefully a quick resolution.

So now, not only does NetWeaver offer support for such standards as HTTP, XML, Web services and of course ABAP, but now it also offers support for Java. All of this adds to SAP’s future interoperability with such applications as Microsoft .NET and IBM WebSphere.

Now that SAP NetWeaver supports Java we will start to see a real positive impact in the marketplace for those who are in search of a cost-effective means to deploy and manage Java applications in their enterprise and small businesses. For companies of all sizes looking for a way to adapt quickly to market changes, respond to unforeseen challenges and to seize new opportunities, SAP NetWeaver is a tool that is worth looking into.
