To verify the problem, the client may need to enable tracing in EMA. We need to enable tracing in both REST and RSSL connections.
1. Create the logging.properties file with the following content in the working directory
.level=ALL
handlers=java.util.logging.FileHandler
java.util.logging.FileHandler.level=ALL
java.util.logging.FileHandler.pattern=./emaj%u.log2. Add the XmlTraceToStdout configuration to the Consumer in the EmaConfig.xml. The following example adds the XmlTraceToStdout configuration to the Consumer_4 which is used to connect to RTO.
<Consumer>
<Name value="Consumer_4"/>
<Channel value="Channel_4"/>
<Dictionary value="Dictionary_2"/>
<XmlTraceToStdout value="1"/>
</Consumer>3. Run the application with the following JVM option
-Djava.util.logging.config.file=logging.properties
The interactions for the REST connection are logged in the emaxxx.log file and the interactions for the RSSL connection are printed to the standard output.
With this information, we can verify if it is a problem with the API or the server.
