WPUMFactory.getUserFactory().getEP5User(sapUser) throws null pointer

Hi,

I am trying to use KM API's to read/upload files with KM repository.

Here is the piece of code which throws the problem.

IWDClientUser wdClientUser = WDClientUser.getCurrentUser();

com.sap.security.api.IUser sapUser = wdClientUser.getSAPUser();

IUser epUser = WPUMFactory.getUserFactory().getEP5User(sapUser);

I have tried printing all the returns and till " sapUser" its fine and returns value as expected.

However the line WPUMFactory.getUserFactory().getEP5User(sapUser) throws null pointer exception.

I am using SAP NetWeaver 7.3.

I have also checked and found in WebDynpro reference > Sharing reference -- > PORTAL:sap.com/com.sap.km.application is added.

Also it seems getEP5User is deperecated in 7.3. What is the latest code to create the ResourceContext ?

Could some one help me with this.

Thanks.

Regards,

Milton.
