My area of expertise are:
Java EE 5 @SAP and SOA. Java EE 5 has become a slim, codesaving version, which has become competitive with óther script languages and to a certain extent with ABAP. Tool support is very well and is increasing. My favorite is eclipse calissto and europe, but also Netbeans. eclipse offers automatic creation wizards esp. for creating web service clients.
What I still miss in Java EE is the support of complex business data type (SAP: global datatypes). Therefore we offer additions like the SAP NetWeaver web service libraris and DDIC.
