Automate Java RCP Builds for Deployment with JNLP: A Comprehensive Guide

In the world of software development, achieving an efficient and seamless build process is crucial, especially when it comes to deploying your Java RCP (Rich Client Platform) applications using JNLP (Java Network Launch Protocol). While many resources provide insight into using Eclipse PDE (Plugin Development Environment) for builds, they often leave developers wanting for more clarity in executing automated builds specifically for JNLP. This blog post will guide you through the steps necessary to automate these builds and how to deploy with JNLP effectively.

Understanding the Challenge

Before diving into the solution, let’s highlight some key aspects that can make automating deployments of Java RCP through JNLP challenging:

  • Complexity of Eclipse PDE: The Eclipse PDE build scripts can be complex to navigate, especially for developers who are new to the automated build process.
  • Manual vs. Automated Processes: While creating a deployable package can be done manually through the Feature Export, automating the entire build process requires a different approach and skill set.
  • Lack of Comprehensive Resources: There’s a scarcity of clear guides that provide step-by-step instructions on automating builds specifically for JNLP deployment.

Steps to Automate Java RCP Builds with JNLP

1. Familiarize Yourself with Eclipse PDE Build Scripts

The first step is to get acquainted with how the org.eclipse.pde.build scripts work. Understanding these scripts will provide a strong foundation for automating your builds.

  • Read Documentation: Explore the official Eclipse PDE documentation. A good starting point is the Eclipse Building Plug-ins guide.
  • Experiment with Sample Projects: Try setting up simple projects using the PDE build process. This hands-on experience will help you grasp the concepts better.

2. Setup Your Build Environment

Ensure that your development environment is prepared for automated builds. Here are some necessary steps to follow:

  • Install Required Software: Ensure that you have the latest version of Eclipse IDE, JRE (Java Runtime Environment), and necessary plugins installed.
  • Configure Your Build System: Depending on your operating system (Windows, macOS, Linux), set up your environment variables and paths correctly for Java and Eclipse.

3. Create a Build Configuration

Create a build configuration that suits your project requirements:

  • Define Your Build Properties: Use the build.properties file to specify the details regarding your build, such as the source location, libraries, and features you intend to include.
  • Setup Target Platform: Specify the target platform in your configuration. Make sure it aligns with the JNLP specifications.

4. Automate the Build Process

Automating the build process can be accomplished using build tools. Here, we’ll focus on a few key tools:

  • Ant and Maven: Both are popular build automation tools that can be integrated with Eclipse PDE.
    • Use Ant to script your build process by creating an Ant script that triggers the Eclipse build.
    • Use Maven’s pom.xml to manage project dependencies and automate the build lifecycle.

5. Deploying with JNLP

After successfully automating your build process, the next step is deploying your application:

  • Generate the JNLP File: Ensure that your build output contains a properly formatted JNLP file. Adjust its contents based on features and libraries of your Java RCP project.
  • Test the Deployment: Before going live, conduct thorough testing to confirm that the application launches correctly via JNLP.

Conclusion

Automating builds for Java RCP and deploying them through JNLP can seem challenging initially. However, with a well-organized approach and the right resources, you can streamline your process effectively. While I haven’t personally gone through this specific experience, I came across a helpful site that outlines deployment practices for Java RCP using JNLP. You can find further details here.

With patience and practice, you can master the art of automated Java RCP builds and JNLP deployment. Happy coding!
