Cause
This scenario is working as designed. It is not a problem. Refer to the "Resolving the problem" section for information.
Resolving The Problem
The failed event manager reports the java.lang.NullPointerException in wbifailedeventmanager.boeditor error under the following circumstances:
- The Service Component Architecture (SCA) application that generated the failed event stops before the failed event manager populates the business data to the failed event manager database.
In this scenario, the SCA application generates a failed event. The failed event is stored in the failed event manager database. The artifact loader queries the application XML Schema Definition (XSD) to populate the business data. However, because the application has already stopped, the operation fails. The artifact loader logs the following warning:
ArtifactLoade W
com.ibm.ws.ral.RALServer getArtifactsInfo Can not get ArtifactLoader instance of app: <application name> please check whether the app existing and started
In the failed event manager, when you click Edit Business Data, it results in the Error reading XML error.
To resolve the problem, start the SCA application. The artifact loader queries the schema and populates the business data in the failed event manager. Additionally, the artifact loader caches the schema information in the WebSphere Process Server runtime memory, which populates the business data even when the application is stopped. - For every failed event, the artifact loader queries the schema at least once so that the business data is cached.
- The cache is cleared when WebSphere Process Server is restarted.
- WebSphere Process Server is restarted and auto-start is disabled for the SCA application.
In this scenario, the SCA application is not set to start automatically when WebSphere Process Server starts. As in the first scenario, the artifact loader cache is cleared when the server is recycled. If you click Edit Business Data, the failed event manager reports the Error reading XML error even for a failed event for which the business data was visible before the server was recycled. To resolve the problem, start the SCA application.
Notes:
This behavior is known behavior for the failed event manager application.
