Java Plug-in - Example: Change the Application Caption

The following are code examples for a plug-in that alters the caption of the Logi application at runtime:

import org.w3c.dom.Document;
import javax.servlet.*;
import javax.servlet.http.*;
import java.util.*;
import java.util.Hashtable;
import com.logixml.plugins.LogiPluginObjects10; import java.io.*;
import java.io.File;
import javax.xml.transform.*;

import javax.xml.transform.stream.*;
import javax.xml.transform.OutputKeys;
import com.sun.net.httpserver.HttpContext;
public class myPlugin
{
public void SetApplicationCaption(LogiPluginObjects10 rdObjects)
{
try
{
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder);
byte b[] = rdObjects.getCurrentDefinition().getBytes();
java.io.ByteArrayInputStream input = new java.io.ByteArrayInputStream(b);
Document xmlSettings = docBuilder.parse(input);
NodeList nl = xmlSettings.getElementsByTagName("Application");
if (nl.getLength() > 0)
{
Node nodApp = nl.item(0);
Element eleApp = (Element)nodApp;
eleApp.setAttribute("Caption", "Greetings from the Sample Plugin!");
rdObjects.setCurrentDefinition(getOuterXml(xmlSettings));
}
}
catch (Exception ex)
{
ex.printStackTrace();
System.out.println("SetApplicationCaption Error " + ex.getMessage());
}
}
}
