I believe you are using Muse incorrectly. The capability classes are server-side artifacts, and based on the muse.xml configuration, Muse will automatically load them with the associated resource.
In your case, you are attempting to manually instantiate a capability from a client, which will not have any resources loaded with it. If you want to invoke a server resource operation, you need to create a client proxy to connnect to the resource. Taking a step back, what exactly are you trying to accomplish? If you are trying to create a server-side capability to read the Apache httpd.conf file: 1) Create the custom capability and override the initialize() method to read the file 2) Add the capability reference to your muse.xml for your resource 3) Deploy your server app, and let Muse load your resource and capabilities. Muse will invoke initialize() on each capability, which will then invoke your code. To invoke your capability from the client side: 1) Generate a client-side proxy to your resource (i.e. Run wsdl2java -proxy on your resource wsdl) 2) Create a test program that uses your proxy, and sends the SOAP request to the remote server resource. -----Original Message----- From: MUSEME [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 12, 2007 3:53 PM To: [email protected] Subject: Re: Muse Resource not initialized Hi Bogdan. Here are the answers to your questions: 1) No errors were found in the catalina.log file, just the foll. INFO items, not sure if they mean anything INFO: Jk running ID=0 time=0/30 config=null INFO: The Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: 2) Here is how I call initialize from my client: // create EPR for test resource URI address = URI.create("http://localhost:8080/http-management/services/http-server";); EndpointReference epr = new EndpointReference(address); MyCapability http = new MyCapability(epr); //http.setTrace(true); try { http.initialize();} catch (Throwable error) {error.printStackTrace();} And here is the code snippet of MyCapability public class MyCapability extends AbstractWsResourceCapability implements IMyCapability { public MyCapability (EndpointReference arg0) { new WsResourceClient(arg0); } public void initialize() throws SoapFault { //super.initialize(); - Commented out as this does not work // Commented out getInitializationParameter as I get the foll. exception // java.lang.NullPointerException at //org.apache.muse.core.AbstractCapability.getInitializationParameter //(AbstractCapability.java:105) //String installDir = getInitializationParameter("httpd-install-dir"); String installDir = "C:\\Program Files\\Apache Software Foundation\\Apache2.2"; Map configParams = null; try { configParams = readConfigFile(installDir+"\\conf\\httpd.conf");} catch (IOException error) { throw new SoapFault("Error while reading httpd.conf.", error); //throw new IOException("Error while reading httpd.conf.", error); } _ServerName = (String)configParams.get("ServerName"); String portString = (String)configParams.get("Listen"); String threadsString = (String)configParams.get("ThreadsPerChild"); _PortNumber = Integer.valueOf(portString); _ThreadsPerChild = Integer.valueOf(threadsString); // The following statement fails with java.lang.NullPointerException ResourceManager manager = getResource().getResourceManager(); ..} 3) The application is built on Axis2. Not sure if this is relevant but when I list "http-server" URI services from Axis2, I see the foll: http-server Service EPR : http://localhost:8080/http-management/services/http-server Service REST epr : http://localhost:8080/http-management/rest/http-server I then click on the http-server hyperlink and get the foll. error: <error> <description>Unable to generate WSDL for this service</description> − <reason> If you wish Axis2 to automatically generate the WSDL, then please use one of the RPC message receivers for the service(s)/operation(s) in services.xml. If you have added a custom WSDL in the META-INF directory, then please make sure that the name of the service in services.xml (/serviceGroup/service/@name) is the same as in the custom wsdl's service name (/wsdl:definitions/wsdl:service/@name). </reason> </error> Bogdan Solomon wrote: > > Can you check your server log and make sure that there are no errors > related to the Axis2 container initialization.
