private static void	loadPluggableProviders() Look for file META-INF/services/org.apache.axis.deployment.wsdd.Provider in all the JARS, get the classes listed in those files and add them to providers list if they are valid providers. Here is how the scheme would work. A company providing a new provider will jar up their provider related classes in a JAR file. The following file containing the name of the new provider class is also made part of this JAR file. META-INF/services/org.apache.axis.deployment.wsdd.Provider By making this JAR part of the webapp, the new provider will be automatically discovered. providers.put(WSDDConstants.QNAME_JAVARPC_PROVIDER, new WSDDJavaRPCProvider()); providers.put(WSDDConstants.QNAME_JAVAMSG_PROVIDER, new WSDDJavaMsgProvider()); providers.put(WSDDConstants.QNAME_HANDLER_PROVIDER, new WSDDHandlerProvider()); providers.put(WSDDConstants.QNAME_EJB_PROVIDER, new WSDDJavaEJBProvider()); providers.put(WSDDConstants.QNAME_COM_PROVIDER, new WSDDComProvider()); providers.put(WSDDConstants.QNAME_BSF_PROVIDER, new WSDDBsfProvider()); providers.put(WSDDConstants.QNAME_CORBA_PROVIDER, new WSDDJavaCORBAProvider()); providers.put(WSDDConstants.QNAME_RMI_PROVIDER, new WSDDJavaRMIProvider()); try { loadPluggableProviders(); } catch (Throwable t){ String msg=t + JavaUtils.LS + JavaUtils.stackToString(t); log.info(Messages.getMessage("exception01",msg)); } ClassLoader clzLoader = WSDDProvider.class.getClassLoader(); ClassLoaders loaders = new ClassLoaders(); loaders.put(clzLoader); DiscoverServiceNames dsn = new DiscoverServiceNames(loaders); ResourceNameIterator iter = dsn.findResourceNames(PLUGABLE_PROVIDER_FILENAME); while (iter.hasNext()) { String className = iter.nextResourceName(); try { Object o = Class.forName(className).newInstance(); if (o instanceof WSDDProvider) { WSDDProvider provider = (WSDDProvider) o; String providerName = provider.getName(); QName q = new QName(WSDDConstants.URI_WSDD_JAVA, providerName); providers.put(q, provider); } } catch (Exception e) { String msg=e + JavaUtils.LS + JavaUtils.stackToString(e); log.info(Messages.getMessage("exception01",msg)); continue; } }
