Clob out of an anonymous block 10g

Question

ver 10.2
trying to get a clob value out of an anonymous block. Been looking at examples but no luck yet ..
Here's a simple example:
*public void doTest2() throws Exception{*
CLOB tempClob = null;
*final String ab ="" +*
*"declare" +*
*" c clob := 'this is a clob';" +*
*"begin" +*
*" :1 := c;" +*
*"end;";*
DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
conn = DriverManager.getConnection(connString,user,pwd);
System.out.println("made connection");
tempClob = CLOB.createTemporary(conn, true, CLOB.DURATION_SESSION);
tempClob.open(CLOB.MODE_READWRITE);
CallableStatement cs = conn.prepareCall(ab);
cs.execute();
cs.close();
conn.close();
my goal is to get the clob from the anonymous block.
Thanks

Connection connection = null;
CallableStatement cStmt = null;
try {
    DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
    connection = DriverManager.getConnection
        ("jdbc:oracle:thin:@<host>:<port>:<sid>", "scott", "tiger");
    cStmt = connection.prepareCall
        ("declare c clob := 'This is a CLOB'; begin ? := c; end;");
    cStmt.registerOutParameter(1, Types.CLOB);
    cStmt.execute();
    Clob clob = (Clob)cStmt.getObject(1);
    System.out.println("Clob: " + clob.getSubString(1L, (int)clob.length()));
} catch (Exception e) {
    e.printStackTrace();
} finally {
    try { cStmt.close(); connection.close(); } catch (Exception ex) { }
}
