Class Dev Not Found Error - commons apache fileupload

[Former Member]

Hello experts,

I have an application deployed on portal as a development component.

I am trying to upload an excel file to my Servlet but getting the below error:

application [K2W_E2E_D~e2e~sce2e~dc_bspend~pg.com] Processing HTTP request to servlet [UploadXLSServletTest] finished with error. The error is: java.lang.NoClassDefFoundError: javax/servlet/http/HttpServletRequest

I have checked that my servlet is getting executed. I am trying to check if request variable has any files by using below code. This is where the servlet is crashing.

if (!ServletFileUpload.isMultipartContent(request)) {

                              // if not, we stop here

                              return;

                    }

I have added the commons-fileupload-1.2.2.jar file to the project as a library project under Used DCs by following the instructions from below document.

http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/60d99678-1a29-2d10-94b4-9d9a67b71...

The upload functionality works fine when deployed on portal as a local project but not when deployed as a Developement Component (DC).

Please provide any suggestions or fixes for the above issue.

Thanks,

Sandeep

Hi Sandeep,

In the app DC, add dependencies "Deploy-Time" and "Run-Time" to your library DC.
