I'm trying to evaluate some non-Axis 1.1 SOAP services that are also servlet-based. One of the
requirements is that they support PHP clients. The one I've found that I'm liking best so far is
called XFire. I've used its example project to create a web service that generates the following WSDL:
<?xml version="1.0" encoding="UTF-8"?>

</wsdl:definitions>
Now, I'm not an expert with this, but the WSDL looks right to me, and to some extent it is... the
following code works:
$bookService = new SoapClient(
"http://localhost:8080/xfire-demo/services/BookService?wsdl";,
array( 'trace' => 1 ) );
$books = $bookService->getBooks();
print_r( $books );
However, the other function does not. The following code breaks:
$bookService = new SoapClient(
"http://localhost:8080/xfire-demo/services/BookService?wsdl";,
array( 'trace' => 1 ) );
$searchBook = "0123456789";
$onlyBook = $bookService->findBook( $searchBook );
print_r( $onlyBook );
When calling findBook(), I get the following SoapFault:
object(SoapFault)#7 (9) {
["message:protected"]=>
string(0) ""
["string:private"]=>
string(0) ""
["code:protected"]=>
int(0)
["file:protected"]=>
string(36) "/usr/local/apache2/htdocs/client.php"
["line:protected"]=>
int(73)
["trace:private"]=>
array(2) {
[0]=>
array(4) {
["function"]=>
string(6) "__call"
["class"]=>
string(10) "SoapClient"
["type"]=>
string(2) "->"
["args"]=>
array(2) {
[0]=>
string(8) "findBook"
[1]=>
array(1) {
[0]=>
string(10) "0123456789"
}
}
}
[1]=>
array(6) {
["file"]=>
string(36) "/usr/local/apache2/htdocs/client.php"
["line"]=>
int(73)
["function"]=>
string(8) "findBook"
["class"]=>
string(10) "SoapClient"
["type"]=>
string(2) "->"
["args"]=>
array(1) {
[0]=>
string(10) "0123456789"
}
}
}
["faultstring"]=>
string(96) "Illegal argument invoking
'org.codehaus.xfire.demo.BookService.findBook(java.lang.String)': null"
["faultcode"]=>
string(6) "Server"
["faultcodens"]=>
string(41) "http://schemas.xmlsoap.org/soap/envelope/";
}
Calling __getLastRequest() gives me (slightly formatted for readability):
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:ns1="http://xfire.codehaus.org/BookService";>
<SOAP-ENV:Body>
<ns1:findBook/>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
Obviously, the required (and passed) parameter doesn't make it to the SOAP request. Is there
anything I can do that will make this work? Or is it a limitation of PHP5's SoapClient? If it is a
limitation, is there any other PHP SOAP client that would work with this WSDL?
Thanks,
Mark
