Reg : load exception

[Mouli Natarajan]

Hi All,

I am working on a web application.Until yesterday it was working fine but suddenly it started throwing this exception.I have all the jars and classpath set in place.

Please help me in this as I am trying to sort this out for a couple of hours.

Thanks in advance.

The mentioned class is missing in the classpath.
To fix the problem just add the mentioned class to the classpath.

As the package name already hints, it is part of Apache Commons Logging which you can get at http://commons.apache.org/logging Download the JAR file(s) there if you don't have yet. The /WEB-INF/lib folder is covered by the classpath and the right place to put JAR files in.

Thanks Bauke.

But i already add the jars to my classpath.It throws an load exception a kind of a new exception.

I dont know how to handle this.

[Bauke Scholtz]

I am just translating the exception.
It is really not in the classpath.
