Will Java be coded into ABAP? How will this work? Are there any papers or books on this subject?

SAP has made several forays into Java over the past few years. They have rolled out a Java-based SAP GUI, developed components external to R/3 in Java, and are now looking to support Java Server pages within the R/3 application server. At this point, SAP has no design to replace ABAP with Java or embed Java directives within ABAP. SAP will be adding a Java virtual machine to their Web Application server, which will allow developers to create Java Server pages that can interact directly with the R/3 application layer. If you are interested in learning more about Java Server pages and Enterprise Java in general, I recommend "Professional JSP 2nd Edition" published by Wrox.
Beyond this, SAP has begun to provide components built as pure Java applications. However, these are product developments that do not require developers to have any ABAP experience.
