I am relatively new to JAVA and am trying to build a back-end application which will call another server where the data is present.
I have to do GET, POST, PUT and PATCH(can live without PATCH) operations to an external server in the intranet. I can hit the exposed service using postman app (using custom header)but want to do the similar action from my Java code, get the output in my Tomcat Server.
I have limitations in modifying dependencies to the POM file or adding jars to the library, so am looking for a solution other than Jersey.
