Hi,

 

The exception error shown above could be because of missing classes, as the compiler is unable to find the particular class., Jar file issue.

 

In the message above, the "org.apache.jasper.JasperExecution" class is not found by the compiler.

A probable solution could be to include the jar file's path in the CLASSPATH; either in Tomcat's CLASSPATH or the project's CLASSPATH.

As is seen in the image posted, the jar file has been placed correctly under the 'lib' directory. However, I doubt if you have missed to include the same in the CLASSPATH.

Also, please check the path and verify if the jar file is present in the path mentioned.

 

Hope this helps !!

Hi,

 

Thank you for ur reply...

 

I have done what u have said....

 

But the problem now is that, the capturing phase of the fusioncharts is successfull. but after that it was not saving the images. and keeps idle.

 

I am not getting what is the problem.

Hi Srinivas,

 

Can you please ensure that the SAVEPATH is proper, i.e it is relative to web application root and the folder to which you are trying to save the image has WRITE permission ??

Hope this helps!!
