ORDS, SODA & JSON in the Database

Hi,

I have installed ORDS 3 in vmware in Oracle Linux 6.5 64-bit. It's working fine, no issue. Now in My production Server I am trying to Install ORDS 3 in Oracle Linux 6.2 64 bit. In the same server Oracle HTTP Server 11(web tier) is also installed. I am looking forward to shift from OHS to Glassfish/ORDS for REST Full web services support in Apex 4.2.6. Now I have also installed Glassfish Server 3.1.2.2 successfully.

When I Issue the Command

$ java -jar ords.war install advanced

Following Error Shows:

[oracle@myserver ords3]$ java -jar ords.war install advanced

Exception in thread "main" java.lang.UnsupportedClassVersionError: oracle/dbtools/jarcl/Entrypoint : Unsupported major.minor version 51.0

Could not find the main class: oracle.dbtools.jarcl.Entrypoint. Program will exit.

I suspect that it is Java version issue so I checked version

java -version
java version "1.6.0_22"
OpenJDK Runtime Environment (IcedTea6 1.10.4) (rhel-1.41.1.10.4.el6-x86_64)
OpenJDK 64-Bit Server VM (build 20.0-b11, mixed mode)

Then I installed jdk 1.7... and checked the installation folder made changes in bash_profile as follows:

JAVA_HOME=/usr/java/jdk1.7.0_79;export JAVA_HOME
PATH=$PATH:$JAVA_HOME/bin:/usr/java/jdk1.7.0_79/jre/bin; export PATH

but still java version is 1.6.0.22. Now since ORDS3 requires jdk 1.7.... I think the issue is with java version. But I cannot make the updated java as the default jdk. How can I do it. Please help

Thanks
