Hi,

I'm trying to run a third-party REST service under EGL/RUI RBD 9.5.0.1 and WebSphere Liberty Profile 8.5.5.8 on localhost.

When I invoke this POST function

            // submit a java batch job            call myJSR352.invokePost("",                    myJSONdata) returning to showResult                    onException serviceError;

the RBD console shows these messages

Websphere Liberty FFDC log appears to indicate a JSON exception

I'm certain the JSON data I moved to myJSONdata variable field is valid because it works on Chrome's Postman REST client.  To be sure I also invoked the third-party REST GET function and that appears to indicate the service is active. (see screenshot)

Any idea what is happening? 

Thanks,

Julius

Hi, oes the third-party REST GET function also receive json data? I guess the problem come from the decode of json. I see glassfish is the console. Do you use oracle jdk for websphere liberty? Try IBM jdk and see what happen.

I will keep looking at this problem.

Hi,

I captured the raw HTTP stream, the REST GET function does not inject JSON data, the parameter value '28' goes into the uri attribute

while the REST POST function put the JSON data into the body attribute

I tried using IBM JDK8 and the error still occurs.

Am I calling the third-party REST within EGL/RUI the wrong way?

            // supply target URI            myJSR352 ICallJSR352{@RestBinding {baseURI = "https://localhost:9444/ibm/api/batch/jobinstances/"}};                        // change to appropriate values            ServiceLib.setHTTPBasicAuthentication(myJSR352, "wlpadmin","xxxxxxxxx");            // NOTE: these EGL calls are asynchronous            // submit a java batch job            call myJSR352.invokePost("",                    myJSONdata) returning to showResult                    onException serviceError;            // show a finished java batch job, e.g., 28 (28th java batch job request)            call myJSR352.invokeGet("28") returning to showResult                    onException serviceError;

Thanks,

Hi Julius. It looks good in EGL side. I need your project to investigate to see what happens between egl prxoy and java batch service. Is it possible that you email your egl project and batch project to me? My email is libbin@cn.ibm.com

Bin.

Thanks Bin, I emailed the EGL and batch projects to libbin@cn.ibm.com

Hi Julius.

It`s a defect of egl proxy,please open an PMR,and I will provide you fix later.

Bin.
 

PMR submitted.  Thanks Bin.
