SAP NW NEO - HTTP404 not found

[Former Member]

Hello experts,

I have just created the Hello World application as described on the help.sap.com page: https://help.netweaver.ondemand.com/default.htm?deploy_ide.html#concept_10CB6EE361554825A778B64F806C....

When I am deploying the application locally it is started and all looks fine. When opening the browser(http://localhost:8080/HelloWorld/) there is an error though.

HTTP404 - /HelloWorld/

The requested resource (/HelloWorld/) is not available.

Where does this error come from? Is it the JRE? Is it MacBook? I am running JAVA SE6(Mac OS X default).

I would appreciate your help.

Best regards,

Fons

Hi Fons,

hm, I'd assume that the URL (HelloWorld) may not be right. In order to make things simply, I'd suggest you do a right-click (open the context menu) on the HelloWorldServlet and pick the 'Run as...' option and then start it that way on your localhost. This should open up a browser window in Eclipse using the right URL.

If that shouldn't do the trick, pls right-click on our localhost server in the "Servers" window, choose 'More' and display the log file. Pls attach the log so that we can have a closer look.

BR,

Hello Matthias,

Thank you for your help. I had already tried to run it on the local server but without success. I have attached the log file, hopefully you can find something.

Hi Fons,

hm, now that looks really strange indeed. Could you send us the full log file?

Hi Fons,

You get 404 because your are requesting the context root of your application. There should be a so called "welcome page" like index.html or index.jsp to have a response other than 404 Not Found.

In order to call the resource you want (servlet in this case), you should call the Run on Server action from the context menu of this resource.

You can check the same issue reported here: http://scn.sap.com/thread/3188416

Hello Fons,

to get your HelloWorldServlet called when you request the context root of your application you would have to edit the web.xml file in WebContent/WEB-INF so that the the url-pattern is / instead of the default /HelloWorldServlet:

<servlet-mapping>

     <servlet-name>HelloWorldServlet</servlet-name>

     <url-pattern>/</url-pattern>

</servlet-mapping>

With that http://localhost:8080/HelloWorld/ should work.

Best regards

Frank
