Method Detail

handles

boolean handles(DeploymentContext context)

Returns true if the passed file or directory is recognized by this sniffer.

Parameters:

context - deployment context

Returns:

true if the location is recognized by this sniffer

handles

boolean handles(ReadableArchive source)

Returns true if the passed file or directory is recognized by this sniffer.

Parameters:

source - the file or directory abstracted as an archive resources from the source archive.

Returns:

true if the location is recognized by this sniffer

getURLPatterns

String[] getURLPatterns()

Returns the array of patterns to apply against the request URL If the pattern matches the URL, the service method of the associated container will be invoked

Returns:

array of patterns

getAnnotationTypes

Class<? extends Annotation>[] getAnnotationTypes()

Returns the list of annotations types that this sniffer is interested in. If an application bundle contains at least one class annotated with one of the returned annotations, the deployment process will not call the handles method but will invoke the containers deployers as if the handles method had been called and returned true.

Returns:

list of annotations this sniffer is interested in or an empty array

getAnnotationNames

String[] getAnnotationNames(DeploymentContext context)

Returns the list of annotation names that this sniffer is interested in. If an application bundle contains at least one class annotated with one of the returned annotations, the deployment process will not call the handles method but will invoke the containers deployers as if the handles method had been called and returned true.

Parameters:

context - deployment context

Returns:

list of annotation names this sniffer is interested in or an empty array

getModuleType

String getModuleType()

Returns the container type associated with this sniffer

Returns:

the container type

setup

com.sun.enterprise.module.Module[] setup(String containerHome,
                                       Logger logger)
                                         throws IOException

Sets up the container libraries so that any imported bundle from the connector jar file will now be known to the module subsystem This method returns a Modules for the module containing the core implementation of the container. That means that this module will be locked as long as there is at least one module loaded in the associated container.

Parameters:

containerHome - is where the container implementation resides

logger - the logger to use

Returns:

the module definition of the core container implementation.

Throws:

IOException - exception if something goes sour

tearDown

void tearDown()

Tears down a container, remove all imported libraries from the module subsystem.

getContainersNames

String[] getContainersNames()

Returns the list of Containers that this Sniffer enables. The runtime will look up each container implementing using the names provided in the habitat.

Returns:

list of container names known to the habitat for this sniffer

isUserVisible

boolean isUserVisible()

Returns:

whether this sniffer should be visible to user

isJavaEE

boolean isJavaEE()

Returns:

whether this sniffer represents a Java EE container type

getDeploymentConfigurations

Map<String,String> getDeploymentConfigurations(ReadableArchive source)
                                               throws IOException

Returns a map of deployment configurations for this Sniffer from the specific archive source.

Many sniffers (esp. Java EE sniffers) will choose to set the key of each map entry to the relative path within the ReadableArchive of the deployment descriptor and the value of that map entry to the descriptor's contents.

Parameters:

source - the contents of the application's archive

Returns:

map of configuration names to configurations for the application

Throws:

IOException - in case of errors searching or reading the archive for the deployment configuration(s)

getIncompatibleSnifferTypes

String[] getIncompatibleSnifferTypes()

Returns:

the set of the sniffers that should not co-exist for the same module. For example, ejb and appclient sniffers should not be returned in the sniffer list for a certain module. This method will be used to validate and filter the retrieved sniffer lists for a certain module

supportsArchiveType

boolean supportsArchiveType(ArchiveType archiveType)

This API is used to help determine if the sniffer should recognize the current archive. If the sniffer does not support the archive type associated with the current deployment, the sniffer should not recognize the archive.

Parameters:

archiveType - the archive type to check

Returns:

whether the sniffer supports the archive type
