hello

Iam able to call a java class file into plsql through 'loadjava' utitlity....But i'm getting prob while calling java package with java stored procedure...
To be clear,here is my java stored procedure:

CREATE OR REPLACE procedure Insertuser(uname varchar2,pwd varchar2) AS JAVA LANGUAGE NAME 'adduser.custins(java.lang.string,java.lang.string )';

With this i'm able to call the java method..but i'm getting prob if i specify the package name where that class is created.
ie.,
'com.effone.package.adduser.custins(java.lang.stri ng,java.lang.string);
Like this i'm not able to call java package.

So anyone can suggest me how to do that..???
