Remember the following when using the code.
- Set your BAM home location where you extracted the BAM pointing to the client-truststore.jks file. for example "/home/aruna/wso2bam/repository/resources/security/client-truststore.jks"
- Set the correct port for publish the data. If you have set an offset change the port accordingly.
- Set the correct username and password for publish data.
Loging to the BAM Admin Console and you'll see the published data as follows.
