Hi guys!

I'm trying to implement soap client via scripting.

I have working php script which consists out of 3 files.
start.php, helloworld1Manager.php and helloworld1Manager.xml

Starting script start.php calls helloworld1Manager.php which gets data
from helloworld1Manager.xml.

I've copied start.php to scripting module mouse1.php. When I'm trying
to run script I'm getting following java console output:




java console output:
ScriptingComponent : Cell 10 : General exception in the whole
mechanism of compiling and executing the script
com.caucho.quercus.QuercusErrorException: /home/domeng/
helloworld1Manager.php:3: Fatal Error: 'class_exists' is an unknown
function.

It would appear that 'class_exists' is not available in the Quercus php code. When I was setting up the Scripting Component I did only minimal testing with the various languages so getting this type of error is not terribly surprising. You will probably need to look for php module(s) that support the functions you want and 'import' those. Please report back how it goes. I would be very interested in the process that you have to go through and I will help if I can.

Thank you. How exactly can I import other module than quercus?
I've checked some quercus examples and require_once (method that
includes other php file) should be supported in theory...

Soap clients with similar file structure also exists in javascript.
Just in case if that php one wont work. Did you do some testing when
main function written in javascript calls external javascript
function ?

Best regards
Domen

I found this reference http://www.java2s.com/Open-Source/Java-Document/EJB-Server-resin-3.1.5/quercus/com/caucho/quercus/lib/ClassesModule.java.java-doc.htm that shows 'class_exists' with three parameters. Is that significant? Regrettably, I have very little experience with php.

Hi!

I've found out that quercus doesn't support(include) soapclient.
That's why my code's not working.
What exactly I have to do to implement other php client? One
supporting soapclient is Project zero http://www.projectzero.org/php/

In order to use a different php scripting engine:

The php implementation must support java scripting interface (jsr-223). I could not determine if the project zero package supports jsr-223.

Since both scripting engines would respond as php engines the Quercus jars must be removed. To do this remove the quercus.jar and resin-util.jar files from the lib directory inside the scripting component.

Insert the new php jar files into that lib directory. There are usually two jar files for a jsr-223 implementation, a language jar and an engine jar.

If a php script runs then everything is good.
