Sudheer,
The problem you got is because your Oracle installation doesn't have the java module as Brian said. Which version of Oracle 10g are you using?
Just in case you are using the Oracle 10g XE, As far as I know, the XE version doesn't come with built-in Java or any of the Oracle-java components or features. You could use Oracle 10g SE or Oracle 10g SE instead. Which distribution of Linux are you using?
