回答1:
Based on the log you have shared, it looks like there are 2 separate errors in your setup. First one is related to XACML mediator configuration and the second one is related to JMS transport configuration. To understand the problem with the XACML mediator, can you share the mediation extension (synapse) configuration you have used with the API?
For the second error, please share the APIM_HOME/repository/conf/axis2/axis2.xml file and axis2_blocking_client.xml files.
Without looking at these configuration files, it is not possible to provide you with an answer.
