PHP SoapClient调用Java Web服务

Question

this is first day I'm looking into Web-Services and I'm already stuck.

I got a simple Java-Code:

@WebService
public class ProductCatalog {

    public void getCategory(String category) {
       System.out.println(category);
    }
}

Then I got the PHP-Code to call this function:

try{
$client = new SoapClient("link/to/wsdl");

$category = "music";

$client->getCategory($category);
}
catch(SoapFault $exception){
    echo $exception->getMessage();  
}

The console output is null.

The following

public void getProducts() {
    System.out.println("Works");
}

with the same PHP-Code works, so the method call itself is working.

As said, it's my first day, so please don't go too hard on me!

edit: here is the WSDL

Answer 1

I encountered the same problem. Call the function like this:

$response = $client->getCategory(array("arg0"=> $category));

I don't know why, but the first parameters of the function is arg0, if it's not working, check the webservice with programs that can connect to webservice, and than you'll get the name of params.
