[jbossws-dev] [Design of JBoss Web Services] - No engine configuration file - aborting!

Hi All, 
 
I 

I am trying to access a web services deployed on JBoss4.0.3 SP1. When I execute the following line of code 
javax.xml.rpc.Service service = factory.createService(wsdlLocation, serviceName); 
I get the following error "org.jboss.axis.ConfigurationException: No engine configuration file"

The following extract explains the problem and proposes a workaround. However I am not sure how to implement the workaround, I would appreciate it if someone can give me some more detail on how to implement this solution.

The default org.jboss.axis.client.Service constructor will throw this exception. My particular case involves creating a new Service object from within an EJB, but this should occur with any client.

Tracing through the code, I discovered that org.jboss.axis.configuration.EngineConfigurationFactoryDefault defines the default filenames for the client configuration as "client-config.wsdd", while the actual file distributed with jboss-ws4ee-client.jar is "axis-client-config.xml". When the Service object is constructed, org.jboss.axis.configuration.FileProvider looks on the classpath for "client-config.wsdd", and of course can't find it.

The workaround specified in JBAS-1106 puts a file with the correct name but possibly the wrong configuration information onto the classpath, where FileProvider can find it. This will work for a standalone client, but not for client code within an EJB, since the Axis packages appear to be loaded with a different classloader than that for the EJB.

The workaround is to provide the Service constructor with a FileProvider that specifies the correct configuration file:
new Service(new FileProvider("META-INF/axis-client-config.xml"))


My source code to invoke the web service is as follows

            // create service factory
            javax.xml.rpc.ServiceFactory factory = javax.xml.rpc.ServiceFactory.newInstance();
            
            // define targetNameSpace
            String targetNamespace = "http://www.openkm.org/"; 
          //  + "wsdl/net.xmethods.services.stockquote.StockQuote/";
            
             // define qname
            QName serviceName =
            new QName(targetNamespace,"OKMAuthService");
            
             // define porname
            QName portName =
            new QName(targetNamespace,"OKMAuthPort");
            
             // define operation name
            QName operationName = new QName("http://localhost:8080/OpenKM/OKMAuth",
            "login");
            
            //Specify wsdl location
            java.net.URL wsdlLocation =
            new java.net.URL("http://localhost:8080/OpenKM/OKMAuth?wsdl");
            
            // create service
            javax.xml.rpc.Service service = factory.createService(wsdlLocation, serviceName);
            
            // create call
            javax.xml.rpc.Call call = service.createCall(portName, operationName);

Thanks in advance
Denzil

 
My source code is as follows 
 
public String login() throws Exception { 
//Method level variables 
String token; 
 
try { 
// create service factory 
javax.xml.rpc.ServiceFactory factory = javax.xml.rpc.ServiceFactory.newInstance(); 
 
// define targetNameSpace 
String targetNamespace = "http://www.openkm.org/";  
// + "wsdl/net.xmethods.services.stockquote.StockQuote/"; 
 
// define qname 
QName serviceName = 
new QName(targetNamespace,"OKMAuthService"); 
 
// define porname 
QName portName = 
new QName(targetNamespace,"OKMAuthPort"); 
 
// define operation name 
QName operationName = new QName("http://localhost:8080/OpenKM/OKMAuth", 
"login"); 
 
//Specify wsdl location 
java.net.URL wsdlLocation = 
new java.net.URL("http://localhost:8080/OpenKM/OKMAuth?wsdl"); 
 
// create service 
javax.xml.rpc.Service service = factory.createService(wsdlLocation, serviceName); 
 
// new Service(new FileProvider("META-INF/axis-client-config.xml")) 
 
 
// create call 
javax.xml.rpc.Call call = service.createCall(portName, operationName); 
 
 
String login = "user1 " + "pass1"; 
// invoke the remote web service 
token = (String) call.invoke(new Object[] {login}); 
}
