Unable to install SAP Netweaver 2004s in Solaris x64

Question

I am trying to install SAP Net2004s in solaris x64 and it has JDK1.6.
For some reason the SAPINST keeps giving error "JDK version 1.5.0 and above is not supported by SAP.
I downloaded and installed j2sdk1.4.2_24_b06 as per note 716604.
Created environment variable as
export JAVA_HOME=/opt/j2sdk1.4.2_24
export PATH=$PATH:$JAVA_HOME/bin
export SAPINST_JRE_HOME=opt/j2sdk1.4.2_24
now if i execute java -version, again it is showing as Jdk1.6
which java
/usr/bin/java
i am able to execute xclock.
I renamed the softlink in /usr/java to java.old and created new one as /usr/java pointed to /opt/j2sdk1.4.2_24
after this if i execute java -version, it gives an error "Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/Object"
Now i checked the java executables, it is located in /opt/j2sdk1.4.2_24/bin/amd64/ (all java executables)
Now i set the env PATH /opt/j2sdk1.4.2_24/bin/amd64 before the variable /ur/bin/java
I tried creating env as "export PATH=$PATH:$JAVA_HOME/bin/amd64". But no luck.
I would really appreciate if someone could help me to pass through this error.
Thanks in advance.

Answer 1

install a fresh JDK just need 64 bit version
and set the environment variables accordingly,
i did install java64bit and out put java -version is j2sdk1.4.2_24 64bit
created env
export JAVA_HOME=/opt/j2dsk1.4.2_24
export PATH=$JAVA_HOME/bin:$PATH
export SAPINST_JRE_HOME=/opt/j2dsk1.4.2_24
export DISPLAY=XXX:0.0
able to execute xclock
But got the same error when i try to execute ./sapinst
error "GUI not Connected......."
i wonder that in java 64 bit,the executables are located in /opt/j2sdk1.4.2_24/bin/amd64/(all java executables)
but when we execute ./sapinst, it shows as it is searching the executables in /opt/j2sdk1.4.2_24/bin
i don't know if that matters.
but just want to let you know that, i was able to get the sapinst gui, when pointing to java1.6 version, but unfortunatly sap won't support above java1.5.
path of java1.6 executables - /usr/jdk/jdk1.6../bin/(all java executables)
Please help me resolving this issue.
