Class GCUBERemotePortTypeContext<PORTTYPE extends Remote>

java.lang.Object
  org.gcube.common.core.contexts.GCUBEContext
      org.gcube.common.core.contexts.GCUBERemotePortTypeContext<PORTTYPE>

Type Parameters:

PORTTYPE - the type of the stub of the remote port-type.

public class GCUBERemotePortTypeContext<PORTTYPE extends Remote>
extends GCUBEContext

Contexts for remote port-types accessed through a locally available distribution of their stubs.

If the distribution is gCube-compliant (e.g. was produced with gCore building facilities), the contexts expose the configuration of the remote port-type and its service, and in fact use it to achieve transparent setting of scoping and security for gCube calls to the port-type.

Normally, clients do not work directly with the contexts, but request a gCube proxy to the conventional port-type stub, which can offer the transparencies mentioned above. Contexts are instead created implicitly, in the process of creating stub proxies. They are then shared across all future requests for proxies of the same remote port-types.

Type Parameters:

PORTTYPE - the type of the port-type stub.

Parameters:

portTypeStub - the original port-type stub.

scopeManager - the scope manager.

callTimeout - the timeout per each call

securityManager - the security manager.

getResource

public InputStream getResource(String resourceName)

Returns a classpath resource given its path. By default, a relative path is resolved with respect to the context implementation.

Overrides:

getResource in class GCUBEContext

Returns:

the resource, or null if the path could not be resolved.

getServiceProperty

public Object getServiceProperty(String prop)

Returns the value of an arbitrary JNDI property (resource or environment) of the service of the remote port-type.

Parameters:

prop - the property.

Returns:

the value of the property.

getProperty

public Object getProperty(String prop,
                          boolean... required)
                   throws RuntimeException

Resolve a configuration property against the naming service. Resolution is relative to the root JNDI context of the naming service and the JNDI name associated with the context.

Overrides:

getProperty in class GCUBEContext

Parameters:

prop - the property.

required - (optional) true if the property is required, false or omitted if property is optional. The only implication is a different handling of failure and logging. Failure in resolving optional properties results in a runtime exception and fatal log entry, whereas failure in resolving optional properties results in a null result and warning in the log.

Returns:

the value of the property, or null if the property was optional and could not be resolved.

Throws:

RuntimeException - if the property is required but cannot be resolved.

getService

public GCUBEService getService()

Returns the GCUBEService resource of the service of the remote port-type.

Returns:

the resource.

getDeploymentDescriptor

public org.apache.axis.deployment.wsdd.WSDDService getDeploymentDescriptor()

public org.globus.wsrf.impl.security.descriptor.ServiceSecurityDescriptor getSecurityDescriptor()

Returns the security descriptor of the remote port-type.

Returns:

protected void parseJNDIConfig(InputStream config)
                        throws Exception

Loads a JNDI configuration file into the JNDI context reserved to remote port-types.

Parameters:

config - the file as a stream.

Throws:

Exception - if the configuration could not be loaded.
