Liferay 7.2 Rest Service module not working, but same code module

Junior Member Posts: 33 Join Date: 2/1/12 Recent Posts

Hi,I created the Liferay 7.1 rest service module based on the Liferay module rest template, and build and deploy in Liferay 7.1 properly working code. But not I am the same module code move to Liferay 7.2 and new build generate and deployed in Liferay 7.2 CE server.
But code not woking asking for "javax.activation" dependencies related error throwing. so I am adding 2 more dependencies related to asking "javax.activation" related. Evenafter adding dependencies throwing an error as below :

Error :::2019-10-22 06:46:44.906 WARN [http-nio-9870-exec-1][PhaseInterceptorChain:88] Application {http://application.rest.sample.com/}SampleApplication has thrown exception, unwinding now

What kind of changes done in Liferay 7.1 and Liferay 7.2 for Rest Service building??

Sounds like this big impressive list of Include-Resource directives includes stuff that you shouldn't include. It's basically the equivalent of compileInclude, which you should avoid if possible - precisely for this reason (and for bloated jar sizes). Depend on the code coming from the OSGi runtime, instead of bringing it all along. You might find different versions available, but you can cater for that. Check this OSGi Basics chapter for compileInclude mechanics (requires free registration).

Deploy successfully and Start Component, But when I call service, showing warning message, but not execute my code.
WARN [http-nio-9870-exec-8][code_jsp:175] {code="404", msg="ProxyServlet: /sample/upload", uri=/o/sample/upload}

What is exactly missing from my end because I am going to Test in my dev environment as a public URL, don't want to any authentication

What I meant was not to exchange your Include-Resource with compileInclude, rather go with compile or compileOnly, and deploy all the secondary dependencies to the runtime environment as well (unless they were already available)
Check which of your dependencies are OSGi bundles, which already are deployed in Liferay (and if their versions match your requirements). If your dependencies are neither deployed already nor OSGi bundles, check if the servicemix project OSGI-ified them already and use those libraries. But don't compileInclude them in bulk. CompileInclude is a last-resort, not a first-responder-tool.
