jPOS field 64 error iso packing

Field 64 error packing with ISOMsg

Here is my code

    ISOMsg o = new ISOMsg();
    o.set(64, "00000000");
    byte[] data = o.pack();

Error:

This question has many problems:

1) It is not real code, it's just a snippet of a few lines. You are now showing where you assign a packager to your newly created ISOMsg

2) Field 64 is a binary field, so you have to set a byte[] instead of String. If you want all zeros, you can try `ISOUtil.hex2byte("00000000");
