Infinite recursion (StackOverflowError)

Hi there,

I am still a newby with spring restful webservice...

I wanna use spring restful service to invoke some of the methods I defined which is supposed to initialise birt enigine instance.

>> Here is my method

Code:

---

@RequestMapping(value="/getBirtEngine" ,method={RequestMethod.GET})
        public @ResponseBody IReportEngine getBirtEngine(){
                IReportEngine iReportEngine = null;
                try {
                        iReportEngine = ReportEngineUtil.getBirtEngine();
                       
                } catch (Exception e) {
                        e.printStackTrace();
                }
                return iReportEngine;
        }

---

and

Code:

---

@RequestMapping(value="/openReportDesign/{reportName}" ,method={RequestMethod.GET})
        public @ResponseBody IReportRunnable openReportDesign(@PathVariable String reportName){
                IReportRunnable runnable = null;
                try {
                        runnable = ReportEngineUtil.openReportDesign(reportName);
                } catch (EngineException e) {
                        e.printStackTrace();
                }
                return runnable;
        }

---

and this is how I am invoking the methods :

Code:

---

IReportEngine engineReportEngine = restTemplate.getForObject(getUri("/getBirtEngine", null),IReportEngine.class);

---

and

Code:

---

IReportRunnable runnable =  restTemplate.getForObject(getUri("/openReportDesign/", reportName), IReportRunnable.class);

---

and this is am error I am getting
