Problem inserting the euro sign using JDBC

Question

Inserting the euro sign into a char field of a DB2 table using JDBC results in getting a control char (SUBSTITUTE / ASCII 26) in the field, instead of the expected euro sign.
I tried both the "old" DB2 driver (db2driver.zip) and the new one (db2jcc.jar). I get the same result in both cases. I also thought this might be a problem of different character sets between the client machine and the database server, but the problem doesn't occur if i use non java third party tools (like WinSQL) to insert the euro sign...
Any idea?

Something like below will verify that you can send the character to the database, store it, and return it with java. You need to run this in a Unicode compliant tool, like Eclipse 3.0.
               //Euro character in Unicode is below, insert it into DB.
               int myCharacterInteger = 0x20AC;
               String myChar = new String(new char[]{(char) myCharacterInteger});
               System.out.println("My character inbound is " + myChar);
               pstmt.setString(1, myChar);
               pstmt.execute();
               pstmt.close();
               //Euro character in Unicode is below, insert it into DB.
               PreparedStatement pstmt2 = dbc
                         .prepareStatement("select * from tmp_junk");
               ResultSet rs = pstmt2.executeQuery();
               while (rs.next())
                    System.out
                              .println("My character from DB is " + rs.getString(1));If that returns the character properly from DB, examine how the character is being input into java, you may inadvertently be changing character sets there.
PS - that may not be right character, but you get the idea. We don't use Euros much where I work. ;-)
