RE: java.lang.ClasssCastException

[Eric Vasilik <er...@bea.com>]

It's best to send questions like these to the public mailing list (mailto:xml-xmlbeans-user@apache.org).  You have a better chance of getting a prompt answer, and others can benefit from your issue.  (Plus, I can procrastinate in hope that someone else answers :-)

I assume you are getting a class case exception at the line:

     max = (UMAXDocument)XmlLoader.load(bookFile);

You are using a very old version of XmlBeans.  XmlLoader was removed quite some time ago.  Depending on the version you have, XmlLoader.load will not automatically detect the document type, thus your cast exception.

I recommend getting the latest V1 buld of xmlbeans:

    http://xml.apache.org/xmlbeans/

and use something like:

     max = UMAXDocument.Factory.parse(( bookFile );

,and a xml file:
<?xml version="1.0" encoding="utf-8"?>
<U-MAX>
    <ReverseEnable>
	<SystemID>906</SystemID>
        <MDN>13012345678</MDN>
        <Password>E9r!399Tsso00ua</Password>
    </ReverseEnable>
</U-MAX>
,when I parse it in my program as this:
File bookFile = null;
    UMAXDocument max = null;
    UMAXDocument.UMAX umax = null;
    ReverseEnableDocument.ReverseEnable rs = null;
    PasswordDocument pd = null;

    try
    {
        bookFile = new File("c:\\max.xml");
        XmlObject x = XmlLoader.load(bookFile);
        max = (UMAXDocument)XmlLoader.load(bookFile);
        umax = max.getUMAX();
        rs = umax.getReverseEnable();
        String password = rs.getPassword();
        String mdn = rs.getMDN();
        System.out.println("password="+password+";mdn"+mdn);
    }
it throw a java.lang.ClasssCastException,can you help me?
Thank you very much!
