Cannot write the suitable source codes for running program

Question

I want to write a program that help student to compile program and run program by using some test cases. For the compiled part, i have been wrote it successfully, but for the run part, i cannot pass the test cases to the program for running. Could any ppl help me to find the problem on the followng codes, why the error will on there? how do i change it? Thanks!
//<!--start get Program Test Case File-->
java.io.BufferedReader TestCaseBuf = null;
Connection con = null;
Statement stmt = null;
ResultSet rs = null;
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
con = DriverManager.getConnection("jdbc:odbc:compas", "sa", "password");
stmt = con.createStatement();
String strSQL = "SELECT testValue FROM TEST_CASE WHERE progID='"+progID+"'";
stmt = con.createStatement();
rs = stmt.executeQuery(strSQL);
try
while (rs.next())
TestCaseBuf = new java.io.BufferedReader(new java.io.InputStreamReader(rs.getBinaryStream("testValue")));                         
finally
if (rs != null)
     rs.close();
if (stmt != null)
     stmt.close();
//<!--end get Program Test Case File-->
//<!--start run program -->
String[ ] args2 = new String[ ]
     "java", "-cp", System.getProperty("user.dir"), FileName
try
     Runtime rt = Runtime.getRuntime();
     Process proc = rt.exec(args2);
     java.io.BufferedReader ireader = new java.io.BufferedReader(new java.io.InputStreamReader(proc.getInputStream()));
     java.io.PrintWriter pwriter = new java.io.PrintWriter(proc.getOutputStream());
String atestcase = null;
     String line= null;
     try
while ((atestcase = TestCaseBuf.readLine()) != null) <------------I found that error seems on here!!!!
     pwriter.write(atestcase+"\r");
pwriter.flush();     
if (atestcase != null)
          if ((line = ireader.readLine()) != null)
          FileOutput = FileOutput + line +"\r\n";
else {break; }
     } //while
     catch (java.io.IOException e)
     out.println("[IOException]. Printing Stack Trace");
     e.printStackTrace();
     pwriter.close();
     ireader.close();
catch (java.io.IOException e)
out.println("[IOException]. Printing Stack Trace");
e.printStackTrace();
//<!--end run program -->

Whats the error message??
Just a guess, but could be (without seeing the error) that you've already closed the TestCaseBuf reader by closing the result set, hence when you go to read it, you're reading on closed reader.
Give this a go...Put the //<!--run program --> code into the result set while loop
while (rs.next())
TestCaseBuf = new java.io.BufferedReader(new java.io.InputStreamReader(rs.getBinaryStream("testValue")));
//<!--start run program -->
...some code
//<!--end run program -->
} Hard to tell without the error message
