How to deploy web application .war file into SAP NetWeaver Engine?

Hi All,

I want to deploy web application which is developped using JAVA web technology into SAP netweaver Engine.

I tried to deploy .war file through SDM but it complained the following error

- Hide quoted text -

"Error loading archive

C;\Document and Settings\cr1adm\Desktop\MyProject.war

  (server side name is: F:\usr\sap\JR1\JC01\SDM\program\temp\MyProject.war)

com.sap.sdm.util.sduread.IIIFormattedSduFileException: The information about development component found in the manifest is either missing or incomplete!

Manifest attributes are missing or have badly formatted value:

attribute keylocation missing

attribute keyname is missing

attribute keyvendor is missing

attribute keycounter is missing

(F:\usr\sap\JR1\JC01\SDM\program\temp\MyProject.war)"

Can any one please suggest how to deploy external web application into SAP netweaver engine.

Is there any procedure to follow to do this.

your inputs will be highly appreciated...

Thanks in advance
