Looking for Webstart Maven Plugin sample application [closed]

Answer 1

I tried the webstart plugin in a prrof of concept involving an embedded tomcat server. The plugin is bound to the package phase and takes a longtime to execute, I would recommend to invoke it manually from the command line. It generates a zip file in the target directory containing the jnlp file and all dependencies. This file can then be extraced and put on a webserver. The url in the pom should point to this path on the server. When started, the app runs a tomcat server on localhost port 8080 with a simple servlet that just returns the requested path as a string.

Let me know if this works for you.

Here is the pom of the project, the plugin configuration was mostly copied from the documentation here

                    true
                    true 

                    
                    false

                     
                    true
                
            
        
    
    
        
            org.apache.tomcat
            tomcat-catalina
            ${tomcat.version}
        
        
            org.apache.tomcat
            tomcat-coyote
            ${tomcat.version}
        
    

Here is a custom template for the jnlp file placed at src/main/jnlp/template.vm, I can't remember why I needed that exactly:

  
    
    $project.Organization.Name
    
    $project.Description
#if($offlineAllowed)
    
#end
  
#if($allPermissions)
  
     
  
#end
  
    
     $dependencies
  
  

This is the main class at src/main/java/net/jhorstmann/embeddedtomcat7/App.java

package net.jhorstmann.embeddedtomcat7;

import java.io.File;
import java.io.IOException;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.servlet.ServletException;
import org.apache.catalina.Context;
import org.apache.catalina.LifecycleException;
import org.apache.catalina.Wrapper;
import org.apache.catalina.startup.Tomcat;

public class App {

    public static void main(String[] args) throws LifecycleException, ServletException, IOException {
        File tmpDir = new File(System.getProperty("java.io.tmpdir"));
        File webappDir = new File(tmpDir, "embeddedtomcat7");
        webappDir.mkdir();

        final Tomcat tomcat = new Tomcat();
        tomcat.setPort(8080);
        tomcat.setBaseDir(tmpDir.getAbsolutePath());
        tomcat.getConnector().setURIEncoding("UTF-8");

        String contextPath = "/";

        Context context = tomcat.addContext(contextPath, webappDir.getAbsolutePath());
        Wrapper wrapper = tomcat.addServlet(contextPath, "Test", new TestServlet());
        //Wrapper wrapper = tomcat.addServlet(contextPath, "Async", new AsyncServlet());
        //wrapper.setAsyncSupported(true);

        wrapper.addMapping("/*");

        tomcat.start();

        tomcat.getServer().await();
    }
}

And finally a servlet at src/main/java/net/jhorstmann/embeddedtomcat7/TestServlet.java

package net.jhorstmann.embeddedtomcat7;

import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class TestServlet extends HttpServlet {

    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        resp.setContentType("text/html; charset=utf-8");
        PrintWriter writer = resp.getWriter();
        writer.println("
" + req.getPathInfo() + "
");
        writer.close();
    }
}
