Unable to apply SPS15 for Portal and KMC to JDW

I am trying to apply SP Stack 15 to Java Developer Workplace, which has been installed from the NW SR1 DVDs with Portal and KMC. The support package for SAP WEB AS Java has completed successfully.

In the next step, to patch Portal, I have to extract the SAR files EP6CTRL15_0-10002786.SAR, EP6TOOLS15_0-20000394.SAR and EP6PORTAL15_0-20000394.SAR and run sapinst again. However, after starting sapinst, I do not see the option for installing the Portal patch for SPS15. How do I complete the patches for Portal and KMC?

Thanks,

Martin Ceronio
