The Data Protocol Handler Filter does not open.

Products

• CA Application Test
• CA Continuous Application Insight (PathFinder)

Issue/Introduction

Not able to open a Data Protocol Handler in the VSM Listen step under Filters.

When selecting a DPH filter, nothing happens.

Cause

It is possible that a new jar file was added to $LISA_HOME/lib folder and is not playing well with DevTest, causing the issue.

Environment

All Supported DevTest releases.

Resolution

When looking at the Workstation log files, exceptions like ClassNotFound were being generated and referring to an external jar file.

Removing the additional jar file from $LISA_HOME/lib folder and restarting the Workstation resolves the issue.

The custom extension needs to be reviewed.
