I am here sharing a nice tool I recently found to draw the diagrams for my final year project at university. When the project is concerned, managing it is challenging with,  code base of the project is pretty large a team is working on the project we need to maintain the quality and performance of the project  proper documentation is also evaluated So we were searching for an easy to use and nice looking tool to achieve the purposes without making it annoying that, we can focus more on the logic and optimization than decorating a diagram. :) That is were I found this plugin for eclipse  called Architexa client, which is free for use. Following is a sequence diagram I generated using the plugin, which didn't take more than 30s to draw than dragging the relevant classes and setting the relevant calls. Following is a class diagram generated, that you can clearly observe the clear and smart look of the diagrams. Pros: From several t...

Through this I am sharing the most simple scenario to follow in using Java keytool for the requirements of Apache Wookie projects digital signature implementation. Anyway if you are looking to know how to generate a key pair or import a certificate to a Keystore using keytool, still this may be helpful. Refer this segment of Java SE documentation to know in-depth details. You needs a configuration of Java in your computer to use keytool and that is enough :). Generating Key Pairs Use following command in command prompt to generate a keypair with a self-signed certificate keytool -genkey -alias wookie -keyalg RSA -keystore wookieKeystore.jks -keysize 4096 After  -alias give the alias to be used for keys           -keylag give the algorithm to be used in key generation          -keystore give the name of the keystore with type .jks (You can give a path here to store the keystore in a desired place)   ...

I am here sharing my GSoC 2012 project details which I enjoyed a lot while learning. This includes a brief introduction on the project with it's design, implementation and guidance on using. The implementation has been done using Apache Santuario 1.5.2 release to generate digital signatures. The project is mentored by Scott Wilson who was so helpful and supported by the community. This is Scott Wilson's post on the project. What is Apache Wookie? Apache Wookie is a Java server application that allows widget uploading and deployment as useful for variety of applications. This may include gadgets to quizzes and games. Wookie has been based on W3C widget specification while providing flexibility on Google Wave gadgets etc. At the moment of writing, it is in the Apache incubator getting ready to graduate as an Apache Project.  Objective of the project The objective this project is to implement the ' W3C XML Digital Signatures for Widgets ' specification i...
