How to execute PL/SQL from Java?

Question

I want to execute (compile) a PL/SQL file to a database and I don't know how it can be done with Java.
Please note that I am NOT trying to call a stored procedure. I know that can be done with CallableStatement.
Background:
My actual requirement is to execute PL/SQL files with error notifications. I tried Ant SQL task; but it fails to give compilation error information. I also tried another open source task called Incanto - that also not that helpful as if I execute in bulk, very hard to figureout which one throws error. Hence I decided to write my own Ant task.

Hi,
do u want to execute PL/SQL files? or just you want to execute the block of code?
in the case of PL/SQL file:
you need to read total file as StringBuffer/String and then execute.
Block of code:
you can directly pass the code to the java file as input and then execute.
Ex:
               StringBuffer queryString = new StringBuffer();
                queryString = queryString.append("BEGIN execute immediate ' ");
          queryString = queryString.append(query);
          //queryString = queryString.append("BEGIN dbms_job.run(142);END;");
          queryString = queryString.append(" '; END; ");
          final_Query = queryString.toString();
          try {
               System.out.println("final :   "+final_Query);
               cstmt = con.prepareCall(final_Query);
               System.out.println("Job is Running...");
               new ThreadCountdownExtThread().start();
               System.out.println("bfore execute()...............");
               cstmt.execute();Note: if you are running pl/sql file read file and save it in a Stirng , and then do the same as above stated
