How to Create and Evaluate XPath Expression in Jav... How to create auto incremented identity column in ... This is the problematic line: NodeList node = (NodeList) expr.evaluate(doc, XPathConstants.NODE); You are mixing two APIs for document parsing and handling, XPath and JSoup. Sigh...But i'm trying to get the code I was given to work, I don't want to write a whole new parser class unless i have to. –user1493803 Jul 1 '12 at weblink

The line should be NodeList node = (NodeList) expr.evaluate(doc, XPathConstants.NODE); You'll probably have to convert it to a jsoup Node (if it exists, I'm not familiar with this API).

What does a -4 above the stave mean? throw an exception } Element pengguna = (Element) penggunas.item(0); EDIT: Later, you've got a bug here: Node username = user.getElementsByTagName("username").item(i); Node password = user.getElementsByTagName("password").item(i); This should be: Node username = user.getElementsByTagName("username").item(0); Do you still see java.lang.ClassCastException in Generics world ? Look, xpath.evaluate will not return an instance of ListNodeList, because you have created that class, so xpath doesn't even know that it exists.

How to parse or convert String to long in Java - 4... It's actually returning a DTMNodeList, which is not a subtype of ListNodeList. Jaxen will work with both of them. Browse other questions tagged java xml jdom or ask your own question.

By using Generics in Collection classes and other places you can safely minimize java.lang.ClassCastException in Java. This leads to ClassCastException if object is not of type on which you are casting it. You need to decide which of both APIs you want to use for your specific job. Why is Professor Lewin correct regarding dimensional analysis, and I'm not?

In fact ClassCastException in Java is one of most common exception in Java along with java.lang.OutOfMemoryError and ClassNotFoundException in Java before Generics was introduced in Java 5 to avoid frequent instances If you want to have a JDOM Document as your output, then your code should likely be: SAXBuilder builder = new SAXBuilder(); Document doc = builder.build(new StringReader("")); For a DOM document But the result makes sense even for core Java since its XPath#evaluate(...) method also usually returns a String (except for one overload). For my money, when learning something complex like this, I would start out with the class's available in the core Java library and go through some tutorials that are available online.

Here are some of the most frequently occurred ClassCastException in Java: java.lang.classcastexception java.lang.string cannot be cast to java.lang.integer This will come when you try to cast String object to Integer i.e. Why getter and setter are better than public field... ► November ( 8 ) ► October ( 13 ) ► September ( 8 ) ► August ( 9 ) ► July When I check the node type of the Node object it says Node.TEXT_NODE. Then you can use the methods you created in your ListNodeList class. (Basically, you wil need to obtain the list of nodes from the DTMNodeList and use it in the constructor
