Calling Stored Procedure with table type as In parameter from Java

Question

Hi Everyone,
Can anyone help me with the sample code to call a stored procedure having input parameter of Table type (consisting of multiple fields) from Java. This job is currently being done by a BPEL process.
We want to implement the same using Java.
Any sample code will be really helpful.
Thanks & Regards,
Vikas

To start using a blob you have to insert it into the database and then get it back. Sounds weird but that is how it is. Here is a very simple program to do this:
#include<occi.h>
#include <iostream>
using namespace oracle::occi;
using namespace std;
int main()
  try
    Environment *env = Environment::createEnvironment(Environment::OBJECT);
    Connection *conn = env->createConnection("hr","hr","");
    string stmt1 = "insert into blob_tab values (:1) ";
    string stmt2 = "select col1 from blob_tab";
    Blob blob(conn);
    blob.setEmpty(conn);
    Statement *stmtObj = conn->createStatement(stmt1);
    stmtObj->setBlob(1,blob);
    stmtObj->executeUpdate();
    conn->commit();
    Blob blob1(conn);
    Statement *stmtObj2 = conn->createStatement(stmt2);
    ResultSet *rs = stmtObj2->executeQuery();
    while(rs->next())
     blob1 = rs->getBlob(1);
    string stmt3 = "begin my_proc(:1) ;end;";
    Statement *stmtObj3 =  conn->createStatement(stmt3);
    stmtObj3->setBlob(1,blob1);
    stmtObj3->executeUpdate();
  catch (SQLException e)
    cout << e.getMessage();
  /* The tables and procedure are primitive but ok for demo
    create table blob_tab(col1 blob);
    create or replace procedure my_proc(arg in blob)
    as
    begin
     -- just a putline here. you can do other more meaningful operations with the blob here
      dbms_output.put_line('hello');
   end;
}Hope this helps.
Thanks,
Sumit
