Question

After deploying my war on my server I get the following error,

org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext

I have checked for the commons-beanutils.jar under WEB-INF/lib folder and it is present there. I have included it under the class path in my build.xml.

Is there anything else I am missing?

I think your server can't find the Converter class in org.apache.commons.beanutils package.Please also check your project build path to see if there is org.apache.commons.beanutils.converter class present or not. If not then Download the latest Commons-Utils jar and add it to in your lib folder. You find the link [here] http://commons.apache.org/proper/commons-beanutils/index.html
