Update PI 7.3 Ehp1

Hello,

I´ve installed a Netweaver 7.3 ehp1 with PI option. After the installation I´ve updated the ABAP part with SPAM tcode and I´ve tried to update Java part with JSPM but I get the this message:

"January 2013: The Java Support Package Manager (JSPM) is replaced by the Software Update Manager (SUM) for SAP NetWeaver 7.3 and higher
The Software Update Manager replaces the Java Support Package Manager for the maintenance of SAP systems based on SAP NetWeaver 7.3 or higher."

I've downloaded SUM10SP09 version,and created the stack xml file because you can't update from SP1 to SP10, or another SP, without the stack xml.

Then process starts and I have to manage the previous stages ABAP tab and JAVA tab, but ABAP software components were updated with SPAM.

What is the process for update only JAVA part?

Thanks a lot.
