I have been working recently with Salesforce, and generating Excel files was not working for me.

It should have been as easy as changing the apex:page contentType property, but its output was like:

<table id="j_id0:j_id1" border="0" cellpadding="0"....

My problem was using

<apex:column>whatever</apex:column>.

Instead, you should use

<apex:column value="whatever" />

and it should work.

Hope this helps.

On October 20th and 21st took place in Madrid the 3rd edition of the biggest Drupal event in Spain, Drupalcamp Spain 2012. On Saturday I participated on a panel with Pedro Cambra, Ramon Vilar, Juampy Novillo and José Reyero about how to contribute to Drupal, with modules, themes, translations, documentation, marketing, events... The slides we used as guide are available on Slideshare:

On Sunday, I made a session where I tried to explain the changes in multilanguage between Drupal 7 and Drupal 8, that will be a reality hopefully on August 2013. The slides are also available in Slideshare:

The videos of every session will be available soon at the Vimeo channel of the Spanish Drupal Association.

That weekend took place the first Assembly of the Spanish Drupal Association, where I was nominated as a Board Member. I hope to contribute with them spreading Drupal use in Spain.

And after a very busy weekend, a plane to Frankfurt. But that's part of another story.

Once you have modelled your stress tests with JMeter (that's another story that deserves its own post), maybe you want to launch them in a non-interactive way from your continuous integration server.

For doing so, you just need to launch JMeter with the non-interactive mode:

./apache-jmeter-2.6/bin/jmeter.sh -t my-test-plan.jmx \
-l my-test-plan-2012-16-09.jtl -n

This commands launch the test plans, but the output file is XML. How could I send this as a report to the QA team or the management people? Just launch:

xsltproc ./apache-jmeter-2.6/extras/jmeter-results-report_21.xsl \
my-test-plan-2012-16-09.jtl > report-2012-16-09.html 

The result will be an HTML file which is rendered as the image attached.
