Access Km repository dynamically from Web dynpro application

[Former Member]

Hi experts,

I need to develop a web dynpro application where there is a link that should connect to a specific repository and pull up the particular document in a folder.

Based on one useful sdn thread, I am using the following code.

I included 3 jar files additionally

security.api.jar

framework.jar

public_api.jar

I dont see anymore errors under the code now, but on the extreme top left corner in the view implementation i see an error synbol showing the following message:

The compilation unit indirectly references the missing type com.sapportals.portal.security.usermanagement.IUserFactory(typically some required class file is referencing a type outside the classpath)

How can I remove this error so that I can test my application?

Thanks

Hi,

additionally you import following jar files

1.com.sap.security.api.ep5

3.prtapi

4.bc.rf.framework_api

5.bc.rf.global.service.urlgenerator_api

6.bc.sf.framework_api

7.bc.util.public_api

check in your code following files are imported or not

import java.io.ByteArrayInputStream;

import com.sap.dictionary.runtime.ISimpleTypeModifiable;

import com.sap.tc.webdynpro.progmodel.api.IWDAttributeInfo;

import com.sap.tc.webdynpro.progmodel.api.IWDModifiableBinaryType;

import com.sap.tc.webdynpro.services.sal.um.api.IWDClientUser;

import com.sap.tc.webdynpro.services.sal.um.api.WDClientUser;

import com.sapportals.portal.security.usermanagement.IUser;

import com.sapportals.wcm.repository.Content;

import com.sapportals.wcm.repository.ICollection;
