Compiling and building JMeter with Eclipse 3.2.x

The developer notes on how to compile and debug Jmeter with Eclipse 1 and 2 are very difficult to follow and outdated. If you are interested in modifying Jmeter using Eclipse 3.2 Callisto you can follow the following procedure: Install Subclipse Callisto release (update site: http://subclipse.tigris.org/update_1.2.x) Download optional libraries. Although they’re optional is better if you download them. mail.jar activation.jar beanshell bsf jexl Use SVN Repository Exploring and add the following repository http://svn.

New views don't show up when using Eclipse RCP setSaveAndRestore

If you add a new view to an Eclipse RCP and when launch it the new view is not there you probably hit the problem described in this CT Arrington’s Weblog post. The IWorkbenchConfigurer.setSaveAndRestore(true) called from your WorkbenchAdvisor can be the source of the problem. The Eclipse RCP platform is trying to restore the perspective from the serialized version stored on disk so it fails to load you new changes. You have several solutions [from the CT Arrington’s Weblog post].

Firefox and file:// Windows UNC paths

The correct way to write a link to a Windows UNC path in HTML is to use this syntax: file://///servername/share/file.txt. But if you try this using Firefox you will quickly find that this type of link only works when using a local html file. If you put the html file in a web server an click on the link there, firefox will silently refuse to load the link. If you open the JavaScript Console (Tools->Error Console) you will find an entry like Security Error: Content at http://.

Scrolling fast with the mousewheel triggers history back and forth

I’m observing an strange firefox behavior when I scroll the page using the mouse wheel. It goes back and forth through search history. So I googled a little bit and found that the KVM switch that I’m using it’s producing bogus key press event that firefox misinterprets. If you are running Linux the solution is simple as you can modify the X server configuration to ignore those events. But I cannot find a suitable solution for Windows.

(Tomcat 5.5.x) java.lang.NoClassDefFoundError: javax/servlet/http/HttpSessionListener

Or java.lang.NoClassDefFoundError: javax/servlet/ServletContextListener for that matter. NoClassDefFoundError on HttpSessionListener , ServletListener , ServletContextListener, etc. can be caused by a custom classloader like Sysdeo DevLoader (I use it with Eclipse) in you Context definition in the Tomcat’s server.xml file. <Loader classname="org.apache.catalina.loader.DevLoader" reloadable="true" debug="1" /> the solution: add useSystemClassLoaderAsParent="false" to the Loader <Loader classname="org.apache.catalina.loader.DevLoader" reloadable="true" debug="1" useSystemClassLoaderAsParent="false"/> This should do the trick.

cvs [xxxxx]: received broken pipe signal

Today I received this error message when issuing a cvs import to the cvs repository cvs [import failed]: received broken pipe signal after googling a little bit I found this mail thread that led me to the following entry in the cvs manual about loginfo: Note that the filter program must read all of the log information or CVS may fail with a broken pipe signal. so I took a look to the CVSROOT/loginfo and the line there was

Netbeans 6.0 Ruby output not working properly ($stdout is not flushed on program termination)

After struggling with Netbeans 6.0 Ruby a little bit I finally found why my puts statement are not working properly. It’s due to the following reported bug.(Vote for this bug!!) Also noted in the RubyTodo page from Netbeans wiki. This problem appears when using native ruby with netbeans instead of jruby. My workaround is using log4r instead for print statements. UPDATE: It has been fixed in the latest version of the ruby module.

Useful WordPress plugin - Redirector

Very useful WordPress plugin to redirect with a “301 moved permanently” from one of your post to any url. I created a Wordpress page out of a post and I wanted to redirect everybody from the post to the the page. My first solution was to include a link to the page in the post but doing an automatic redirect is better as it allows to move the google pagerank from the post’s URL to the page URL
