Struts 2 Starting Problem

[Sven Beckmann]

Hi Folks,

I am new to Struts 2 and I've been trying to get some sample applications running for example this one:
http://www.benmccann.com/dev-blog/struts-2-tutorial-getting-started/
or this one:
http://viralpatel.net/blogs/2009/12/tutorial-create-struts-2-application-eclipse-example.html
But every sample application that is using a <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
in the struts.xml file is causing the following errors:

SCHWERWIEGEND: Error filterStart

Sorry for the long stack trace, but I really don't know how to fix it. I checked the following topic, but the suggestions didn't help.
https://coderanch.com/t/479592/Struts/Getting-Dispatcher-initialization-failed-error

Even if i add the all jars from thestruts-2.1.8.1 package.
Has anyone any ideas or suggestions for me?

Edit:

IDE: Eclipse 3.5
Tomcat 6.0.20
struts-2.1.8.1

Need help...

Thanks anyway!

 Caused by: java.lang.ClassNotFoundException: org.apache.commons.fileupload.FileUploadException 

Seems pretty clear: you're not including the commons-fileupload and/or commons-io libraries.

Do *not* just randomly add "all the Struts 2.1.8.1" libraries, *particularly* the plugins: this will cause your application to fail if you have not also included their transitive dependencies. It can also affect baseline behavior with potentially unintended consequences.

And welcome to JavaRanch!

Hey,

thanks for your reply.
Addind commons-fileupload and/or commons-io won't resolve the problem.
Maybe I've got the wrong versions of them?

I find it very interesting, that the struts sample applications don't use the FilterDispatcher and are therefore working.
I am using the book "Struts 2 in Action" to help me get into the topic a little easier. Their sample applications available at: http://www.manning.com/dbrown/SampleApplication.zip
is using the FieldDispatcher and it is working... so I am probably doing something wrong here...

It'll resolve the problem above, because that's what the problem was.

What libraries are you deploying? (List the libraries you're deploying.)

[David Newton]

You should be using the ng dispatcher if you're using Struts 2.1; the original FilterDispatcher is deprecated. Look at the sample apps that come with the distribution.

But the stack trace above is due to the missing dependencies.

[Sven Beckmann]

Is that the actual name "ngdispatcher"? What it the classpath to it?

Missing dependencies means I have to not only add the files to the web-Inf/lib folder, but also as dependencies to the project?

Thanks!

[David Newton]

I don't remember the full path off the top of my head; "ng" is one of the package name. Hang on...

*googling*

org.apache.struts2.dispatcher.ng.filter maybe?

Libraries needed by the web app must be deployed with the web app.

[Sven Beckmann]

Hey

Solved the problem.
The FilterDispatcher is simply not available in the newer StrutsCore jarlibrary.
It exists in 2.0.11 thoug, so i simply use an old core and it works.

I find it very surprising that there I couldn't find any hint on that online, with the error message I got.

The package you said, nd.Filter is not working either, but I am gonna google it myself...

Thanks anyway!

Edit
{
New filter is this:
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
from the new Struts 2 exmaple applications
}
