Hi,
I've got a bizarre problem regarding form validation. A simple form is
validated, and when failing this validation I get a blank html page with
the following source: <html><body></body></html>
The last message in the log is:
Validation failed, returning to '/upload.jsp'
I've read in another thread that somone else experienced the same thing.
The solution in this case was to use a different commons-validation.jar.
I'm using exactly the same jars as the validation example application.
Still with the same result.
Why am I not receiving the original form, like in the validation example?
I've included the following files for review:
- upload.jsp // The file containing the html.
- web.xml
- struts-config.xml
- validation.xml
- UploadBean.java
Any help would be greatly appreciated!
Kind regards
Rune Bjørnstad

This is the Struts configuration file for the example application,

NOTE: You would only flesh out the details in the "form-bean"
declarations if you had a generator tool that used them to create
the corresponding Java classes for you. Otherwise, you would
need only the "form-bean" element itself, with the corresponding
"name" and "type" attributes.
