[Restlet with Spring DM]

2008-11-10T17:27:00.000-08:00

How you can create restlet with Spring DM

1. need update 6 files
- web.xml
- applicationContext-osgi.xml
- applicationContext.xml
- MANIFEST.MF
- TestApplication.java
- TestDefaultResource.java

2. main point

use "org.restlet.component" as context-param

in web.xml add below line

3.
[context-param]
[param-name]org.restlet.component[/param-name]
[param-value]component[/param-value]
[/context-param]

4. "component is from "applicationContext.xml" file

[bean id="component" class="org.restlet.ext.spring.SpringComponent" ]
[property name="defaultTarget" ref="application" /]
[/bean]

5. "application" is from same file "applicationContext.xml" file

[bean id="application" class="applicationPackage.TestApplication"][/bean]

6. TestApplication.java
import TestDefaultResouce;
import org.restlet.Application;

JSON : Array List <> JSON

2008-07-07T19:13:00.001-07:00

Converting method between array List and JSON

You need some jar files.
1. json-lib-2.2.2-jdk15.jar
2. commons-beanutils.jar
3. commons-lang.jar
4. commons-collections.jar
5. commons-logging.jar
6. ezmorph-1.0.4.jar

Please set classpath those jar files.
And here is sample source to change from ArrayList to JSON.

import java.util.ArrayList;
import java.util.List;

import net.sf.json.JSONArray;

public class testA {

/**
* @param args
*/
public static void main(String[] args) {

List mybeanList = new ArrayList();
mybeanList.add("S");
mybeanList.add("b");

JSONArray jsonA = JSONArray.fromObject(mybeanList);
System.out.println(jsonA);
}

}
