Access KM APIs from J2EE Web Application

[chinna_babu2]

Hi Experts,

Is it possible to access KM API's to create resources, folders etc. from outside of the SAP EP/KM.

I have developed Enterprise Application Project and deployed it to SAP J2EE engine. But when I try to call KM API's to create resource I am getting the below exception

java.lang.NoClassDefFoundError: com/sapportals/wcm/crt/CrtClassLoaderRegistry

.

To be able to access the KM repository we need to set the Sharing Reference "knowledgemanagement" in Dynpro applicaitons, but not sure how to add this Sharing Reference to Enterprise Applications.

Please suggest me how to acheive this.

Thanks

Chinna...

Hi Chinna,

yes this is possible.

You have to modify the application-j2ee-engine.xml file. If you open it in NWDS there is a folder "References" and by clicking "Add" you can add the needed references. In the opening dialog you select "Create new" and then you just enter the name of the portal application that you want to reference (as you would do it in Sharing References... but aliases like "knowledgemanagement" don't exist in here, so you have to add each single reference). Target type is "application" and reference type is "weak".
