Cannot create a .dat file using the Repoconvert command
This happens when the value of tibco.class.path.extended property is missing the following entry in the RepoConvert.tra file:
%TPCL_HOME%/tomcat/server/lib
Add the missing entry to the tibco.class.path extended property.
1. Open the RepoConvert.tra file, located in the following directory:
<TIBCO_HOME>\tra\<version>\bin
2. Look for tibco.class.path.extended and append the path <TIBCO_HOME>/tpcl/<version>/tomcat/server/lib
3. Save the RepoConvert.tra file.
