Stored Procedure error in Java

Question

My Java application is invoking stored procedure(Oracle 10g). The stored procedure is opening a cursor for a SQL query that is created dynamically in side the procedure. Whenever there is an error while opening the cursor (i.e. executing the SQL query), I get the following exception message in Java application logs irrespective of what error has caused during SQL execution.
SQLException for SQL [{call PRC_TEST(?, ?, ?, ?, ?, ?, ?, ?)}]; SQL state [60000]; error code [604]; ORA-00604: error occurred at recursive SQL level 1
ORA-01003: no statement parsed
; nested exception is java.sql.SQLException: ORA-00604: error occurred at recursive SQL level 1
ORA-01003: no statement parsed
e.g. If the query is like select * from tableA and I dont have proper privlieges. I should get error message while opening the cursor :- insufficient privileges.
Is there any way where we can get more precise(or exact!) error message (in Java application logs) that stopped SQL execution while opening the cursor?

Answer 1

I'm using a callable statement.
The strange thing is that, when i remove all IN and OUT paramters in the java code and the stored procedure, both the call to the stored procedure and teh execution of the stored procedure works.
The moment I add in just a IN parameter (in the stored procedure, and setting it in the java code) it stops working, and i receive this error.
java.sql.SQLException: ORA-06550: line 1, column 23:
PLS-00103: Encountered the symbol "" when expecting one of the following:
:= . ( @ % ;
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:114)
heres the java code and stored procedure
CREATE OR REPLACE PROCEDURE sampleProcedure(tax out number)
is
BEGIN
tax := 10 *.15;
/END;
CallableStatement statement =conn.prepareCall("{call sampleprocedure ?}");
statement.registerOutParameter(1,java.sql.Types.INTEGER);
statement.execute();
ResultSet rs = statement.getResultSet();
if((rs = statement.getResultSet()) != null){
