Hi
I found there would be an error "error parsing result" while call by JSON-RPC and we could not get the actual error message if the java code threw a exception, which results from the error message is not valid JSON string, for example: {"error":com.ibm.iq.innovation.marketplace.biz.exception.BizException: A Group named Jacky's team already exists.,"id":2} So I think it would be better to fix it like this: =>Line 246 in org.apache.tuscany.sca.binding.jsonrpc.provider. JSONRPCServiceServlet: Change the following code: => jsonResponse.put("error", e.getCause()); to the code as follows: => /********************************************************** * add json error object into error so that * the client javascript can parse them correctly. */ Throwable t=e.getCause(); JSONObject jsonError = new JSONObject(); jsonError.put("code", HttpServletResponse.SC_INTERNAL_SERVER_ERROR); jsonError.put("msg", t.getMessage()); jsonError.put(;"trace", t.getClass().getName());); jsonResponse.put("error", jsonError); /************************************************/ Best regards!
