HttpUtils2 Problem

[Firpas]

Hi Erel,
I've a problem with HttpUtils2,
When i make a HttpJob.Download(Url) or PostString(Url, sString),
if the server (url) is down i have the follow error:
java.lang.RuntimeException: java.lang.NullPointerException
at anywheresoftware.b4a.BA.raiseEvent2(BA.java:195)
.....
And the event "JobDone" don´t raise.
With HttpClient and HttpRequest, you have two events:
ResponseError (Response AsHttpResponse, Reason AsString, StatusCode AsInt, TaskId AsInt) and
ResponseSuccess (Response AsHttpResponse, TaskId AsInt)
What's the solution?
Thanks ins advance for your cooperation.

This is strange. Have you modified HttpUtils2 code?

Please run it with the debugger to see the exact error line (and also post the full error message).

This is not exactly the same problem but is similar.

Did you try calling the Download procedure in a Try..Catch statement?

Maybe this way you can avoid the application error, and proceed with something else if the remote server is down

Have you modified HttpUtils2 code?

Can you post the full error message and the line that raises the error?

You have still didn't answer my previous question.

 

[Firpas]

If your first question is if i´ve modified HttpUtils2 code
the answer is no.

And i don´t konw what other question

 

[Erel]

The second parameter to HttpJob.Initialize is the module that will handle the JobDone event. You should change that line to:

Job.Initialize("Job", Me)

The second parameter to HttpJob.Initialize is the module that will handle the JobDone event. You should change that line to:

Job.Initialize("Job", Me)

Thanks for your help and sorry for my mistake,
Do not know why, but I thought that the second parameter was the id of the task

Thank you again
