Hi I am trying to use KM API in servlet .

I am not sure what library to mention in references in

application-j2ee-engine.xml in EAR.

Code is as follows .

Code is printing out.print(ume4User.getFirstName());

if remaining section of code is not there . Otherwise its throwing ....

Application error occurred during request processing.

Details: java.lang.NoClassDefFoundError: com/sapportals/wcm/crt/CrtClassLoaderRegistry The ID of this error is

Exception id: [000C29882910004F0000000C000013E800040A8E05AA8CB7].

PrintWriter out = response.getWriter();

out.print("Lakshmi");

com.sap.security.api.IUserFactory iFactory=UMFactory.getUserFactory();

com.sap.security.api.IUser ume4User = null;

try {

ume4User = iFactory.getUserByLogonID("administrator");

out.print(ume4User.getFirstName());

} catch (Exception e) {

// TODO Auto-generated catch block

out.print(e.getMessage());

}

com.sapportals.portal.security.usermanagement.IUser ep5User = null;

try {

ep5User = WPUMFactory.getUserFactory().getUser("administrator");

} catch (Exception e1) {

// TODO Auto-generated catch block

out.print(e1.getMessage());

}

IResourceContext resourceContext = new ResourceContext(ep5User);

RID rid = RID.getRID("/documents");

IResource resource = null;

try {

resource =

ResourceFactory.getInstance().getResource(

rid,

resourceContext);

response.getWriter().println(resource.getName());

} catch (Exception e2) {

// TODO Auto-generated catch block

out.print(e2.getMessage());

}

Hi Link says about sharing references for a portal application portalapp.xml ... i am doing a J2ee application ... so i am worried what to specify run time references to avoid my problem.

TRy this with application-j2ee-engine.xml

<?xml version='1.0' encoding='UTF-8'?>

<!DOCTYPE application-j2ee-engine SYSTEM 'application-j2ee-engine.dtd'>

<application-j2ee-engine>

<reference reference-type="weak">

<reference-target provider-name="sap.com" target-type="library">oracle</reference-target>

</reference>

<classpath>c:/lib/XYZ.jar</classpath>

<fail-over-enable mode="disable"/>

</application-j2ee-engine>

Here I have given two example one is direct ref to a jar file called XYZ.jar

another if you have created a libarary using Visual Admin Tool & u wanted to establish a relationship between the ur application and this library called "oracle"

I guess you can do the first approach, In such case you don't need to bundle XYZ jar as part ur ear file, This will do the trick.

One more thing please remove the application manually using Visual Admin tool before deploying using this descriptor

It works by this .

To Talk to KM we need

<application-j2ee-engine>

<reference

reference-type="weak">

<reference-target

provider-name="sap.com"

target-type="application">com.sap.km.application</reference-target>

</reference>

<provider-name>sap.com</provider-name>

<fail-over-enable

mode="disable"/>

</application-j2ee-engine>
