java errors---on install

attempting to install webacc. sles 11 sp 2 --- during configuration process I get prompted to install java 1_6_0.

I couldn't find the java 1_6_0-ibm rpm to install on the srvr so I downloaded jre 1.7.5.. here is some output

grpwise2:/tmp # rpm -Uvh jre-7u15-linux-x64.rpm
