Which jar files have you added to your project?

This error is because it is nof finding the LogFactory class. I guess it is in apache-loging jar file: http://commons.apache.org/logging/

Download and add it to you project, but it is not the only jar file you need to work with Jasper. Here you have the list of jar files I'm using for my actual project, you will need some of them (not all, for example DynamicJasper is not necessary to test your program):

- commons-beanutils-1.7
- commons-collections-2.1
- commons-logging-api-1.0.2
- dom4j-1.6.1
- DynamicJasper-3.0.0
- DynamicJasper-3.0.0-tests
- iText-2.1.0
- jasperreports-3.1.2
- jaxen-1.1.1
- jdtCompilerAdapter
- xalan

Hope this helps.
