Hello yasosaran,

i have created a custom dashlet using java:

1) Comment out the block in ${tomcat}\shared\classes\alfresco\web-extension\custom-slingshot-application-context.xml


   <bean id="webframework.searchpath" class="org.alfresco.web.scripts.SearchPath">
      <property name="searchPath">
         <list>
            <ref bean="webframework.remotestore.webscripts" />
            <ref bean="webframework.store.webscripts.custom" />
            <ref bean="webframework.store.webscripts" />
            <ref bean="webscripts.store" />
         </list>
      </property>
   </bean>
‍‍‍‍‍‍‍‍‍‍‍‍

Remember in web-framework-application-context.xml exists:

   <bean id="webframework.store.webscripts.custom" class="org.alfresco.web.scripts.ClassPathStore">
      <property name="mustExist"><value>false</value></property>
      <property name="classPath"><value>alfresco/web-extension/site-webscripts</value></property>
   </bean>‍‍‍‍

2) put your desc file in

${tomcat}\webapps\share\WEB-INF\classes\alfresco\web-extension\site-webscripts\org\alfresco\demo\simple.get.desc.xml

<webscript>
  <shortname>The World's Simplest Webscript</shortname>
  <description>Hands back a little bit of JSON</description>
  <family>user-dashlet</family>
  <url>/demo/simple</url>
  <authentication>none</authentication>
</webscript>‍‍‍‍‍‍‍

3) Modify

${tomcat}\webapps\share\WEB-INF\classes\alfresco\webscript-framework-application-context.xml:

add after

   <!–  Abstract Web Script Implementations –>
   <bean id="webscript" abstract="true"/>
‍‍‍

 <bean id="webscript.org.alfresco.demo.simple.get" class="org.alfresco.module.demoscripts.SimpleWebScript" parent="webscript"/>‍

4) deploy your Java backed Script as jar in WEB-INF/lib

package org.alfresco.module.demoscripts;

import java.io.IOException;
import java.io.Writer;

import org.alfresco.web.scripts.AbstractWebScript;
import org.alfresco.web.scripts.WebScriptException;
import org.alfresco.web.scripts.WebScriptRequest;
import org.alfresco.web.scripts.WebScriptResponse;
import org.json.JSONException;
import org.json.JSONObject;

public class SimpleWebScript extends AbstractWebScript {
   public void execute(WebScriptRequest req, WebScriptResponse res)
         throws IOException {
      try {
         // build a json object
         JSONObject obj = new JSONObject();

         // put some data on it
         obj.put("field1", "data1");

         // build a JSON string and send it back
         String jsonString = obj.toString();
         Writer writer = res.getWriter();

         //writer.write(jsonString);
          writer.write("<div class=\"dashlet\">");
          writer.write("<div class=\"title\">SIMPLE WEB SCRIPT</div>");
          writer.write("<div id=\"SIMPLEWEBSCRIPT\" class=\"body scrollableList\">");
          writer.write("<h1>SIMPLE SIMPLE</h1>");
          
          writer.write("</div>");
         
          writer.write("</div>");
                   
      } catch (JSONException e) {
         throw new WebScriptException("Unable to serialize JSON");
      }
   }
   
   
}

After deploying (refreshing web scripts) you can see this web script at:

http://localhost:8080/share/service/demo/simple

you can add this dashlet to dashboard…

but there is only one problem: dashlet will be not displayed on dashboard - phase render problem??
