NoClassDefFoundError

[Former Member]

Hi All,

I have developed a custom Portal component. Getting the below error.

I have already added the JAR com.sap.portal.pcd.roleservice_core to the classpath. Please if someone can suggest what is missing.

Hi Nikhil,

When you add the JAR to the Classpath you are only providing a so-called design time reference so that the IDE (eclipse) can build your project. When you actually run the code (on the server) it also needs to be able to resolve the class and you do that by telling it in the portalapp.xml that it needs to reference the class at runtime.

In the portalapp.xml you will see a SharingReferences area where you can specify runtime references. This is where you need to provide the reference for this Role Service you want to use. In this case I think you would need to reference com.sap.portal.pcd.roleservice_core

Here is more info on the SharingReferences property:

Hope this helps,

Simon

Thanks Simon.

I have added the reference com.sap.portal.pcd.roleservice.

Portalapp.xml looks as follows.

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

<application>

  <application-config>

    <property name="startup" value="true"/>

    <property name="SharingReference" value="com.sap.portal.pcd.roleservice,htmlb,com.sap.portal.pcd.glservice,com.sap.portal.pcmbuilderservice,usermanagement"/>

    <property name="ServicesReference" value="com.sap.portal.ivs.api_iview, com.sap.portal.ivs.api_landscape"/>

  </application-config>

  <components>

    <component name="test">

      <component-config>

        <property name="ClassName" value="test"/>

      </component-config>

      <component-profile/>

    </component>

  </components>

  <services/>

</application>

The error persists. I have checked and found that class file ROOT/WEB-INF/portal/portalapps/com.sap.portal.pcd.roleservice/private/lib/com.sap.portal.pcd.roleservice_core.jar

Thanks,

Nikhil
