Deploy warning - The requested resource [Servlet] is not found

[Former Member]

Hey,

I always get the same error while deploying any application in NWDS.

Introducing for example, I created a Servlet that takes use of a bean in order to perform a simple login.

The welcome-page is invoked properly.

However after inserting the values (e.g. password and username) for the bean instance, I get HTTP Error-code 404:

Error: The request cannot be processed.
Troubleshooting Guide https://sdn.sap.com/irj/sdn/wiki?path=/display/jsts/home
 Details: The requested resource [errServlet] is not found.

I found a related thread () and a troubleshooting guide (http://wiki.sdn.sap.com/wiki/pages/viewpage.action?pageId=221358404) concerning this problem.

However none of the solutions fixed my problem.

Summary in Deployment log:

Description:
		1. Warning occurred on server 6350250 during update com.sap/simpleErrExample_EAR : Web Class Existence Test: servlet class "ex.errServlet" cannot be found in the application class path.

In simpleErrExample_EAR navigate to DC Metadata..

Now open DC Definition -> Used DCs now here you need to point to all required JARs.

For you it will be servlet_jsp i guess....

You will find them in SAP-JEE SC

try to add all DC references there.
