Tool to assist in debugging classpath issues in Java Web Applications

Classloader Servlet project consists of two servlets: one to search for from which location is a particular class loaded; and the other to list the complete classpath (in the order of loading) available to the web application. Deployment is just copying the Jar file into your web application's /WEB-INF/lib directory.

New cli tool: Tree

One of the tool I missed most when I switched to Mac from Linux was the tree command. I wrote a new tool Tree (available from WizTools.org mini-projects) in Java which has similar functionality as Unix tree. This tool is an executable Jar:

$ java -jar tree-0.1.0-jar-with-dependencies.jar

The output is similar (not same) to Unix tree command. The tool also supports command-line options:

LDAP Password Change Validation

Our QA team was in dilemma today: there was a HTML form which collected change password request, and updated the user password in LDAP on success scenario. There was no login form corresponding to this to validate if the password has been successfully updated in LDAP. To help the team, I developed a quick tool to test the LDAP by binding the user to it. The tool source is available here: http://code.google.com/p/wiztools/source/browse/#svn%2Fldap-auth-validator%2Ftrunk

Usage:

$ java -jar ldap-auth-validator-1.0-SNAPSHOT-jar-with-dependencies.jar \
                                    -u <ldap://host:port/base.dn> [user-cn]

On executing the command, the tool will ask the user to input password. If the password allows the user to bind to the ldap, SUCCESS output will be printed.

Web Tester (online tool hosted in Google App Engine)

Web Tester is a online tool to host your HTML page temporarily in a web-url. The tool is configured to expire content after 24 hours of publishing.

This tool was developed for a specific use in a project I was involved with. In this project we used Schema.org defined rich snippets for SEO purposes. For testing this we required Google Rich Snippets Testing Tool. Unfortunately, Google's tool was available for use only for pages available in the internet. I had to enable my team to test content during development itself. So, I developed this tool wherein the development version of the pages can be web-enabled for immediate testing using Google's tool.

I am sure this is just one use of this tool. I am sure users could find many other interesting uses of it.

The source code of the tool is available here: http://code.google.com/p/gae-web-tester/.

The JavaDoc API is also available.

Launching Java API for oEmbed 1.0 Specification

I am happy to announce the launch of WizTools.org oEmbed Java API project. This is an implementation of the oEmbed specification. The aim of this project:

• Minimal external dependency. Maybe, the only external dependency I forsee is for JSON parsing.


• XML parsing is done by super-fast StAX.


• API should be easily extendable.


• Validation for compliance to the specification should be in place.


• Should be available in Maven public repository.

The initial version of the code is committed in the mercurial repository---interested hackers, have a look!

CSS Import Resolver 0.3.0 Released

CSS Import Resolver is a new tool from WizTools.org Mini-projects.

Including the combined-css in your webpages will improve the performance of the site by avoiding additional HTTP roundtrips. More information in this wiki.

JFind by Tom Ball

During my younger days, I remember visiting:

http://weblogs.java.net/blog/2005/09/03/jfind-simple-jar-file-locator

This became one of my most valuable tool in my Java programming life. The tool basically finds the Jar file(s) which has the searched class in it. The tool is executable from command-line.

The trouble with the tool was unavailability of it in binary-executable form. So I had copy of this tool in my cloud drives so that I can fetch from any machine any time.

Recently I was in need of this tool, again. I thought: would it not be good if I am able to build the tool and give an executable version of it, for all to download? So it is here:
