json - groovy: how to catch exceptions on AsyncHttpBuilder -


I am trying to create an async call in a domain. The following code works fine if I specify a valid address with the json response, but when the address is not valid, I want to capture any possible exceptions.

How can I catch exceptions back? / p>

A quote from StackTrace here:

Message: Invalid JSON string

...

http.AsyncHTTPBuilder - Exception throw From the given response reporter: groovyx.net.http.HTTPBuilder$RequestConfigDelegate@420db81e

Code here: 

  def http = new asyncHTTPBuilder (poolSize: 1, contentType: ContentType.JSON) Def futureResult futureResult = http.request ("http://www.notexistingdomainxyzwq.com/", Method.GET, ContentType.JSON) {response.success = {resp, json -> Log.info ("success")} response.failure = {resp, json -> Log.info ("ERROR")}} log.info ("call start"); try {while (! futureResult.done) {log.info ('waiting ...') log.info ("done: $ {futureResult.done}") Thread.Sleep (1000)}} hold (east) { Log .error ("excellence $ {prior}")} log.info ("full call")    
 
 
 If you ask to block  futureResult.get ()  and wait for the result, it will throw the exception that you can hold:  < pre>  try {def result = futureResult.get () "login.info" ("dan: $ result")} hold (former) {log.error ("excel $ {east}")}  < / Pre>

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
