SQL Exception from Java program

[jyotigupta6]

Hi

I am getting this exception when I am invoking stored procedure through java program.
java.sql.SQLException: ORA-20000: ERROR -911: ORA-00911: invalid character
ORA-06512: at "PDREPADM.RUN_EXTRACTION", line 119

program :

sql_extraction_sp = "{CALL pdrepadm.Run_Extraction(?,?,?,?)}";
cs_extraction_sp = (OracleCallableStatement) objConnection.prepareCall(sql_extraction_sp);



cs_extraction_sp.setString(1,strQueue);
cs_extraction_sp.setInt(2, iPartition);
cs_extraction_sp.registerOutParameter(3, OracleTypes.CLOB);
cs_extraction_sp.registerOutParameter(4, OracleTypes.NUMBER);
rset = cs_extraction_sp.executeQuery();
System.out.println(" Resultset :" + rset);
Clob clob = cs_extraction_sp.getClob(3);
System.out.println("clob :" + clob);

BufferedReader reader = new BufferedReader(clob.getCharacterStream());
String line = null;
while (( line = reader.readLine()) != null)
{
System.out.println(line);
}
reader.close();
