I want to use distribute tracing to link together the front end tracing and the backed java application to create a distributed tracing.
i am using rum-js by injecting it to the page as well as java agent in the tomcat server.
How to make distribute tracing work? How can i connfigure the rum js and java agent to be linked together with a same trace id?

You have to configure distributedTracingOrigins: ['domain1','domain2',...] on the JS agent

You may also need to enable CORS on the Java side
