ISoMessage unpacking Exception

[Abdullah Al Noman Opu]

I just want to parse an ISO message using Jpose, For that, I wrote some code like  as follows.... and having an exception like

 Exception in thread "main" org.jpos.iso.ISOException: org.jpos.iso.IF_CHAR: Problem unpacking field 41 (java.lang.StringIndexOutOfBoundsException: String index out of range: 120) unpacking field=41, consumed=112


bellow is my code and xml file . Can someone tell me Why I am facing this exception and what can I do to solve this !!!!! 

public static void main(String[] args) throws IOException, ISOException {
    // Create Packager based on XML that contain DE type
    GenericPackager packager = new GenericPackager("/src/main/resources/field.xml");

    // Print Input Data
    String data = "0410723A40010E808000164445167778029910000000000000011300012609410310058515403701260126581400100000000585 0910000001050";
    System.out.println("DATA : " + data);

    // Create ISO Message
    ISOMsg isoMsg = new ISOMsg();
    isoMsg.setPackager(packager);
    isoMsg.unpack(data.getBytes());

    // print the DE list
    logISOMsg(isoMsg);
}

private static void logISOMsg(ISOMsg msg) {
    System.out.println("----ISO MESSAGE-----");
    try {
        System.out.println("  MTI : " + msg.getMTI());
        for (int i=1;i<=msg.getMaxField();i++) {
            if (msg.hasField(i)) {
                System.out.println("    Field-"+i+" : "+msg.getString(i));
            }
        }
    } catch (ISOException e) {
        e.printStackTrace();
    } finally {
        System.out.println("--------------------");
    }

}
