    HTTP Status 404 - Could not find resource for relative....

    Guo-Guang Chiou Newbie

      I deploed a process and then able to retrive process information by posting url like "http://localhost:8080/gwt-console-server/rs/process/definitions.

      the json result is as below:

      {

      -definitions:[

           {

                id: "hello:,

                name: "HelloWorld",

                version: 0,

                packageName: "defaultPackage",

                deploymentId: "N/A",

                suspend: false      

           },

      .

      .

      .

      .

          ]

      }

       

      i follow the url format as below to delete the hello process.

      POST/gwt-console-server/rs/process/definition/{id}/remove
      */*application/json

       

      at the end, the  result is as following.

      HTTP Status 404 - Could not find resource for relative : /process/definition/hello/remove of full path: http://localhost:8080/gwt-console-server/rs/process/definition/hello/remove


      type Status report

          I changed my way to delete process resources by using "http://anonsvn.jboss.org/repos/riftsaw/trunk/samples/quickstart/management/src/org/jboss/riftsaw/management" .

           

          It's ok to delete the process's instance.

           

          however, when it comes to delete the process, it shows the result as the following:

            from the log trace: java.lang.UnsupportedOperationException

             

            This means this operation is not supported.

              Hi Jeff,

               

              thanks for your reminding.

               

              by the way, if i want to delete a process deployed, how can i do it any way?

                Jeff Yu Master

                In which project? jBPM or RiftSaw? If it is in RiftSaw, you can remove the bpel artifact from the deploy folder. I don't think we have exposed this operation as a RESTful web serivce. I am not sure about the jBPM side.

                  No description is provided.

                   

                  So I tried one of rest api which I think is to delete a process.

                  At last, it can not work.

                  Any way, thank you very much Jeff.

                   

                  I will keep trying these APIs and see its result.
