Hi,
VMC is a component that is integrated into the SAP NetWeaver AS ABAP. It provides a JRE that is compatible with J2SE 1.4. However, we should not to be confused with the SAP NetWeaver AS Java, which provides a runtime environment that is completely compatible with J2EE.
Starting with kernel 7.01, the VMC is available in each release. The VM container patches are contained in the DW.SAR archive or in the SAPEXE.SAR archive.
For rest all cases ABAP will use Java only during installation..
Thanks
