JBossAS5 deployers for JBossESB 4.x
Background
In the ESB you can specify that a service should be exposed as a WS. Upon deploying the service a web-app will get generated
and deployed. As part of this process a number of files get generated, like the servlet, jaxws handlerchain, wsdl file.
In JBoss AS 4.x this was done by actually creating a .war file on the local filesystem, but in AS5 it is done by using a
number of deployers.
I'm having a problem with making a generated wsdl available the WS deployer. Following are the details of this issue.
One of our deployers has the responsibility of generating the WSDL file and also putting it into an in-memory virtual file system:
public class EsbWsdlDeployer extends AbstractSimpleVFSRealDeployer<EsbMetaData>
{
/** Logger */
private Logger log = Logger.getLogger(EsbWsdlDeployer.class);
/**
* No-args constructor.
*/
public EsbWsdlDeployer()
{
super(EsbMetaData.class);
setStage(DeploymentStages.POST_CLASSLOADER);
setOutput(JSEArchiveMetaData.class);
setOutput(EsbMetaData.class);
}
@Override
public void deploy(final VFSDeploymentUnit deploymentUnit, final EsbMetaData esbMetaData) throws DeploymentException
{
final List<WebserviceInfo> endpointServices = esbMetaData.getModel().getWebserviceServices();
if (endpointServices != null && endpointServices.size() > 0)
{
log.info("Deploying webservices for : " + esbMetaData.getDeploymentName() + ", " + deploymentUnit.getClassPath());
try
{
URL dynamicClassRoot = new URL("vfsmemory", esbMetaData.getDeploymentName(), "");
for (WebserviceInfo webserviceInfo : endpointServices)
{
final ESBServiceEndpointInfo serviceInfo = new ESBServiceEndpointInfo(webserviceInfo);
final String wsdl = ESBContractGenerator.generateWSDL(webserviceInfo, serviceInfo, deploymentUnit.getClassLoader());
URL wsdlUrl = new URL(dynamicClassRoot + "/" + serviceInfo.getWSDLFileName());
VirtualFile wsdlFile = MemoryFileFactory.putFile(wsdlUrl, wsdl.getBytes());
deploymentUnit.addClassPath(wsdlFile);
URL resource = deploymentUnit.getClassLoader().getResource(serviceInfo.getWSDLFileName());
log.info("WDSL loaded with classloader: " + resource);
log.info("WDSL deploymentUnit: " + deploymentUnit.getClassPath());
log.info("WDSL : " + wsdlUrl);
}
}
catch (final Exception e)
{
throw new DeploymentException("Failed to create webservice artifact", e);
}
}
}
}As you can see I'm logging a lot in this deployer to show what is happening:

You will also notice that I try loading the wsdl from the deployments classloader to be sure that it has access to the wsdl.
Next, the following error is recieved during deployment (slightly modified to that it's easier to read the paths):

Now to me, it looks like when the web service is getting deployed it does not have access to the deploymentunits classpath. It can see all the files in the real .esb archive but not the in-memory files that were created previously by our deployers.
Any thoughts or suggestions on this?
