[Asterisk-java-users] Is this a bug?

[Jason W. <ja...@cl...>]

Hello,

The following code hangs evertime on my machine.  It's because of the
concatenation; if I take it out (dmail=email1+email2+email3;) then it works
fine... How can I further nail down the problem? I get 'INFO: Received
Connection.' and nothing else... subsequent to failure, calls to this script
show 'SEVERE: no script configured' error

I ran your script here with A-J 0.2 with a ResourceBundleMappingStrategy
and besides the fact that it doesnt do anything it run well - even
multiple times.

thank you,

as it turns out... I can't concatenate String variables in java on this
machine!? (weird I know) This thing in a main runs on my test and
devolepment machines fine, then get's to the production machine as a service
and fails... even in a main)

As this is now a Java/Linux problem I'll be off topic if I proceed, but any
ideas would be very helpful.  I looked in var/log/messages and
var/log/secure and found nothing.  I was running the SElinux and turned that
off, the problem may have started when I did this.

what JDK are you running on that machine? a sun one or some of the
"free" ones like kaffee that sometimes come shipped with linux distros?
try a java -version
You probably want to make sure you are actually running a recent sun (or
bea jrockit) jdk there.

RE:SOLUTION FOUND [Asterisk-java-users] Is this a bug?

[Jason W. <jas...@be...>]

I finally found the problem listed below and wanted to communicate it
because perhaps it will be a help to others.

I had reset the classpath on the machine, and it was not correct(typo).  I
was able to run all types of simple java programs so I thought that this
couldn't be the problem.  However, I was not able to concatenate strings.
Someone on the groups told me that the chance of the program failing on that
line (where the concatenation was) was 0%. Saying the chance of anything
failing is 0% is probably never appropriate, as there is always a
possibility, and in this case, was the direct key to the problem.

The class needed to perform string concatenation couldn't be found at
runtime and therefore the DefaultAGIServer just hung, and then gave a severe
error on subsequent requests. Is there a way to simply change the way this
server works so that it would give detailed error information to the screen
when this type of thing happens? would this be a worthwhile change? I had
the code in the agi in try-catch blocks, with a system.out of the exception,
but didn't see this on the screen. running the program in main I was able to
see the problem, so I'll do this quicker next time. perhaps this was more
about honing my debugging technique than anything else! :)

Thanks again Stefan for your hard work on Asterisk-Java.

If I should consider a change (e.g. better logging) I need more
information about the cause, i.e. which class was not available and
where did DefaultAGIServer hang?
Did you enable log4j logging and checked that this error was not
reported in A-J's logs?

silently failing without either a log entry or an exception being thrown
is bad and should be fixed.

I think what you would probably want is for all errors to be logged and =

you can configure a log4j appender to output errors to the console if =
that
is where you want them to go.

Normally you wouldn't want this sort of library, asterisk-java, to =

anything to System.out. =20

[Asterisk-java-users] HELP: Fast AGI exed return value.

[Brett S. <bs...@no...>]

Help..................

I've written a Fast AGI application which calls 
BaseAGIScript.exec("txfax", data);

The application txfax is called successfully.

I have two problems.

1. txfax returns a value of -1 but the return from the call to 
BaseAGIScript.exec("txfax", data) returns a value of 0.

2. I have modified app_txfax.c to set a channel variable to indicate 
indicate the actual reason for the failure. When I attempt to retrieve 
the channel value null is returned:

e.g.
<code>
String resultVar = getVariable(SubmitFax.FAX_RESULT);
</code>

where SubmitFax.FAX_RESULT is defined as:
<code>
public static final String FAX_RESULT = "FAX_RESULT";
</code>


The relevant txfax code uses:
<code>
        ast_log(LOG_DEBUG, 
"==============================================================================\n");
        ast_log(LOG_DEBUG, "Fax send not successful - result %d.\n", 
result);
        ast_log(LOG_DEBUG, 
"==============================================================================\n");
        char varResult[64];
        sprintf(varResult, "%d", result);
        pbx_builtin_setvar_helper(chan, "FAX_RESULT", varResult);
<code>

The last lines of the txfax_exec method is:

<code>
    ast_log(LOG_DEBUG, "returning=%d\n", res);
    return res;
}
</code>


The log file displays the following:

Mar  9 22:41:44 DEBUG[18786] app_txfax.c: 
==============================================================================
Mar  9 22:41:44 DEBUG[18786] app_txfax.c: Fax send not successful - 
result 3.

Hi Brett,

you dont have access to the return value through AGI afaik.

> 2. I have modified app_txfax.c to set a channel variable to indicate

yeah thats the way to go. (and with Asterisk 1.2 return values are
deprected in favor of channel variables anyway)

I dont see why "FAX_RESULT" isnt set correctly and "FAX_DEBUG" seems to
be ok... did you do anything different regarding those two variables?
Are you sure your code in app_txfax.c is executed? Maybe some debug
logging statements help there.
