Re: [Simple-support] Attribute always returning null or 0

[Simon B. <sim...@if...>]

Hello Shobhit,

Maybe you should have a look at the tutorial in the beginning. It's quite good and obviously you did not spend much time on it. For example the @Root annotation is absolutely missplaced, it should be at the beginning of the class. And with respect to the "data " attribute look up the @Path annotation. 

Use the tutorial to learn about the features of simple-xml step by step. You will find that your problem can easily be solved by adopting examples from the tutorial. 

Best Regards,

I am new to Simple Framework and have written a simple program to
deserialize an xml file to java objects using Simple. I am able to do
it partially but the attribute always return null or 0. The code and
the test xml is shown below:

Below is the class
file-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

import java.io.File;

import org.simpleframework.xml.Attribute;
import org.simpleframework.xml.Element;
import org.simpleframework.xml.ElementList;
import org.simpleframework.xml.Root;
import org.simpleframework.xml.Serializer;
import org.simpleframework.xml.core.Persister;

public class Deserialize {

/**
* @param args
*/

//@Attribute(name="code" , required=false)

@Root
private String datadef;

@Element
private String str;

@Element
private String state;

@Attribute(name= "code",required=false)
private int code;

@Attribute(name="id", required=false)
private int id;

public static void main(String[] args) throws Exception {
// TODO Auto-generated method stub


Serializer serializer = new Persister();
File source = new File("importFiles/test.xml");

Deserialize deserialize = serializer.read(Deserialize.class, source);
System.out.println("Str : " + deserialize.str);
System.out.println("State : " + deserialize.state);
System.out.println("Code : " + deserialize.code);
System.out.println("Id : " + deserialize.id);
}

}

Below is the sample xml file I am trying to
deserialize-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

<datadef>
    <str>123</str>
<state code="100" id="4">test</state>
</datadef>


I am not able to understand what is the mistake I am doing. Thus
seeking for immediate help.

thanks and regards
