Hi to all;
I am implementing such File uploading application as well as i am written an fileUpload interceptor in struts.xml file but
i dont know how to get related values of file into my Action class.

When i use like;
public String uploadFile()
File filePath = new File("/",uploadfile.getUploadFileName());
return SUCCESS;

then it throws an error follows;
Caused by: Unable to load bean org.apache.struts2.dispatcher.multipart.MultiPartRequest (jakarta) - [unknown location]
at org.apache.struts2.config.BeanSelectionProvider$ObjectFactoryDelegateFactory.create(
at com.opensymphony.xwork2.inject.ContainerBuilder$4.create(
... 20 more

What is the mean of this error
Can Somebody tell me.

I'm not sure what you are trying to say here. If you are using the default fileUpload interceptor provided by struts 2.x, then all you need to do is expose action properties corresponding to the file upload form field. So if your form which upload the file looks like this

Then in your Action class you can have three properties which will be automatically set the fileUpload interceptor. These are
The first object is the File object of the uploaded file, 2nd is the mime type of the file and the third is the name of the uploaded file...

Also make sure you have commons-io and commons-fileupload libraries deployed.
