Guys please help me solve this problem, I'm trying to create an xml doc and later make it a json object, any suggestions any one

[wim DC]

NoClassDefFound is usually a missing library (jar).

Nah, i don't know but i can't find that class, can I not instantiate XMLSerialzer the way I tryd?
Then will you please tell me how

[wim DC]

That class probably comes out of the commons-lang-2.x.jar (apache)
- Where's that XmlSerializer from?
- Is that a web project, or normal java application?
- Does it use maven?
- What IDE do you use?

[Mozana]

maven ? I dont no what dat is, its a web appl;
The habitat of the serializer "is import net.sf.json.xml.XMLSerializer";
I am using netbeans 7
Sorry for taking so long, n tnx.

so i added it, but i how do i reference the xml

[wim DC]

1) Do you want to do XML to JSon, or JSon to xml?
2) Do you have the XML in a file or a String?
3) Look at the method summary of XMLSerializer (Overview (json-lib jdk 5 API)) The api isn't that hard. It's very clear which method to pick for each case.

[Mozana]

I want from xml to json

[wim DC]

Then use one of these:

Quote

[TABLE="width: 100%"]
[TR="class: TableRowColor, bgcolor: white"]
[TD="width: 1%, align: right"] JSON[/TD]
[TD]readFromFile(File file)
Creates a JSON value from a File.[/TD]
[/TR]
[TR="class: TableRowColor, bgcolor: white"]
[TD="width: 1%, align: right"] JSON[/TD]
[TD]readFromFile(String path)
Creates a JSON value from a File.[/TD]
[/TR]
[TR="class: TableRowColor, bgcolor: white"]
[TD="width: 1%, align: right"] JSON[/TD]
[TD]readFromStream(InputStream stream)
Creates a JSON value from an input stream.[/TD]
[/TR]
[/TABLE]

JSONObject json = JSONObject.fromObject("{\"name\":\"json\",\"bool\":true,\"int\":1}");

XMLSerializer xmlSerializer = new XMLSerializer();

        JSONObject json = (JSONObject) xmlSerializer.read(xmlResult);

The first line is the one that's got error, the thing is i dnt get hw duz dat line throw exception.
