Problems with message binding

[jpuerta]

Greetings...

We have been trying to use the message binding with SCA, but we have
been unsuscessful...
We were trying to do this as shown here:
http://www.osoa.org/display/PHP/binding.message+Binding+Documentation
But when we try to generate the Message Service Description (http://
yummyphpprojjpuerta/services/activemqtest/TestService.php?msd), we
obtain this error:

Fatal error: Class 'SCA_Bindings_ms_ServiceDescriptionGenerator' not
found in /usr/local/php/lib/SCA_SDO-1.2.3/SCA/Bindings/message/
ServiceRequestHandler.php on line 49

We also noticed, that when we load the SAM extension, for some reason,
wsdls generated by SCA have 1 empty line at the beginning of the
document, rendering the xml invalid... the browser complains with this
error:

XML Parsing Error: xml declaration not at start of external entity
Location: http://yummyphpprojjpuerta/services/activemqtest/TestService.php?wsdl
Line Number 2, Column 1:<?xml version="1.0" encoding="UTF-8"?>
^

Many thanks in advance for any help you may offer...

Hi, sorry to hear you are having problems.

The Fatal error you are seeing looks odd: the _ms_ in the middle of
the name looks like something somewhere is looking for a binding.ms
rather than binding.message. I propose we try with an exaple that I
know works - I show below a simple example that I have just tried out
on my machine with ActiveMQ 5.0. I am running with the FULMAR branch
of SCA but I don't think that should make any difference.

As for the second error you report, the empty line, one reason for
that can be a blank line in the php script on the receiving end - the
one that is supposed to generate the wsdl. If there is a blank line
before the first <?php, it comes out in the wsdl. In fact if any of
the scripts that are involved in generating the wsdl emit anything
before the <?xml declaration we get trouble - but I hope that the SCA
scripts never do that.

Here is my working example. See if it works for you. It's three files
which for me are all in C:\Program Files\Apache Group\Apache2\htdocs
\Frankfurt\Message
where htdocs is of course the document root for my apache.

Of course you need to start ActiveMQ in one window and
ReceivingService.php in another. You'll see that the test client gets
the receiving service to generate the msd file and writes it out, then
makes a local call to the sending service which sends the magic
initials IBM on queue://receiver

I get a couple of annoying messages from the SAM extension but that is
because I run php with strict messages i.e. show all errors - in any
case they are nothing to worry about.

Good luck and do let me know how you get on.

Matthew

Hello Matthew...

Thank you very much for your help...
I tried the example you provided, but i was unable to get it to
work...
I still get the same error when I try this:

http://yummyphpprojjpuerta/services/activemqtest/ReceivingService.php?msd


Fatal error: Class 'SCA_Bindings_ms_ServiceDescriptionGenerator' not
found in /usr/local/php/lib/SCA_SDO-1.2.3/SCA/Bindings/message/
ServiceRequestHandler.php on line 49

I checked the line 49 in this file, and it looks like this:
SCA_Bindings_ms_ServiceDescriptionGenerator::generateMPD($service_description));

After that I browsed for the same file in the FULMAR branch you were
referring to (http://cvs.php.net/viewvc.cgi/pecl/sdo/SCA/Bindings/
message/ServiceRequestHandler.php?
hideattic=1&view=markup&pathrev=FULMAR), and found that the same line
looks different than the one in the SCA version we downloaded:

SCA_Bindings_message_ServiceDescriptionGenerator::generateMSD($service_description));

we downloaded the SCA_SDO stable version 1.2.3 from here:
http://pecl.php.net/package/SCA_SDO/

Again... thank you for your help

Good, that sounds as if that has fixed the problem for you. How about
the second one - a blank line in the wsdl? Did you find the source of
the problem for that too?

You'll see I have just released 1.2.4, by the way.

Hi Matthew...

Unfortunately, we have still been unable to run a successful test with
the message binding...
The fatal error complaining about the class with "ms" in the name,
disappeared... creating the msd file works now, but trying with the
example you provided... we run the ReceivingService in one window, and
get the following output:

[root@was6testserver activemqtest]# /usr/local/php/bin/php
ReceivingService.php

Listener for queue://receiver has been started. To exit, press <Ctrl>
+ <C> ...

Activemq is running on another window...
But when we run the test client it still fails displaying the
following error:

Fatal error: Uncaught SCA_RuntimeException: Send Request Failed thrown
in /usr/local/php/lib/SCA_SDO/SCA/Bindings/message/Proxy.php on line
120

At this point we really don't know what we are doing wrong...
We installed activemq 5.0.0 on the localhost and on some other
server... but it made no difference

We are also still getting the blank line generating WSDLs and any
other XML file generated by sca, including the msd file... we still
don't know why this happens... but this behaviour only occurs, when
the sam extension is loaded... without it, all the wsdls are generated
fine...

We are using SCA_SDO version 1.2.4 now...

Any suggestion will be appreciated...
Thank you very much

jpuerta...

Hello,

The blank line in the WSDL may be caused by the carriage return at the
end of file 'php_sam.php' (PECL bug #11034).

In that case, i think you have used the current releases (1.1.0) of
SAM, and I am afeard this version does NOT support some features of
the message binding ( including the STOMP protocol ). Unfortunately,
i've no idea when the next release of SAM becomes available. in the
mean time, you may wish to try a patch file[1] and rebuild SAM
extension yourself. Good luck!

Jack

[1]  the patch file can be found at this link http://groups.google.co.uk/group/phpsam/files
(named sam_patch.txt), there is also a zip file contains the whole sam
folder with the latest sources code.

Jack, thanks for this very timely and authoritative reposnse.

jp, if you want, I can try and build the version of the zip file that
Jack's posting refers to and make sure that our samples run with that
precise level. Or you can try it first. Let me know what you would
like. And...are you on Windows or Linux or something else?

Hello Jack, Matthew...

I downloaded the zipfile, and successfully compiled Jack's version of
the sam extension...
But after loading the extension, php no longer works and we see a
segmentation fault in the logs, so I was unable to test the example...

I am testing all this on Linux...
We have
php 5.2.5
apache 2.2.6
activemq 5.0.0

Thanks
jpuerta
