I need to load a part of code dinamically by using Jquery and Json.
This is my struts.xml :
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<constant name="struts.enable.DynamicMethodInvocation" value="false" />
<constant name="struts.devMode" value="true" />
<package name="model" extends="struts-default">
<action name="UserManager" class="model.UserManager">
<result>index.jsp</result>
</action>
</package>
<package name="test" extends="json-default">
<action name="giveMeJsonData" class="test.testAction" method="myFunction">
<result type="json"><param name="root">jsonData</param></result>
</action>
</package>
</struts>
this is my testAction class :
package test;
import com.opensymphony.xwork2.ActionSupport;
import java.util.LinkedHashMap;
public class testAction extends ActionSupport {
private LinkedHashMap<String, String> jsonData;
public LinkedHashMap<String, String> getJsonData() { return jsonData; }
public void setJsonData(LinkedHashMap<String, String> jsonData) { this.jsonData = jsonData; }
@Override
public String execute() throws Exception {
return SUCCESS;
}
public String myFunction() {
jsonData = new LinkedHashMap<String, String>();
jsonData.put("My name is", "marco");
return SUCCESS;
}
}
and i call that method with a submit :
<s:div id="my_result" >
<s:property value="jsonData" />
</s:div>
<s:form action="giveMeJsonData" theme="simple">
<sj:submit targets="my_result" value="Example" />
</s:form>
Problems :
1 - Unfortunatly, when i try to Run the application, server log (tomcat) says :
Unable to load configuration
Error building results for action UserManager in namespace
regarding the line <action name="UserManager" class="model.UserManager">
, and
There is no result type defined for type 'json' mapped with name 'success'. Did you mean 'json'?
regarding <result>index.jsp</result>
2 - When i click on Example button, i don't get the Json element.
What am I wrong?
Cheers
UPDATE 1
<package name="json-default" extends="struts-default">
<result-types>
<result-type name="json" class="com.googlecode.jsonplugin.JSONResult"/>
</result-types>
</package>
<package name="test" extends="json-default">
<action name="giveMeJsonData" class="test.testAction" method="myFunction">
<result type="json"><param name="root">jsonData</param></result>
</action>
</package>

It seems you took this kind of example.
Try with this struts.xml :
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<constant name="struts.enable.DynamicMethodInvocation" value="false" />
<constant name="struts.devMode" value="true" />
<package name="test" extends="json-default">
<action name="giveMeJsonData" class="test.testAction" method="myFunction">
<result type="json"><param name="root">jsonData</param></result>
</action>
</package>
</struts>
And you have to include the json plugin in /WEB-INF/lib
.
I use a different way.
struts.xml :
<action name="getjson" class="myclass" method="getJson">
<result name="success" type="stream">
<param name="contentType">application/json</param>
<param name="inputName">inputStream</param>
</result>
</action>
Method :
public String getJson() {
String json = "({ 'var1': 'value1', 'var2': 'value2' })";
inputStream = new ByteArrayInputStream(json.getBytes());
return SUCCESS;
}
Update :
I changed the struts.xml. The json-default
package is defined in the plugin.
Update 2 : This setup worked for me.
struts.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<constant name="struts.enable.DynamicMethodInvocation" value="false" />
<constant name="struts.devMode" value="true" />
<package name="TestJson" extends="json-default">
<action name="giveMeJsonData" class="test.testAction" method="myFunction">
<result type="json"><param name="root">jsonData</param></result>
</action>
</package>
</struts>
I had a problem with jsonplugin-0.34 I used struts2-json-plugin-2.1.8.jar instead. But the error I had has nothing to do with yours : It was "java.lang.ClassNotFoundException: com.opensymphony.xwork2.util.TextUtils"
If the example button pop a download window, try this for the jsp page :
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<%@ taglib prefix="sj" uri="/struts-jquery-tags" %>
