BEA WebLogic Server 9.0 API Reference

weblogic.deploy.api.model
Class WebLogicDeployableObject

java.lang.Object
  weblogic.deploy.api.model.WebLogicDeployableObject

All Implemented Interfaces:

weblogic.deploy.api.internal.Closable, DeployableObject

Direct Known Subclasses:

WebLogicJ2eeApplicationObject

public class WebLogicDeployableObject

extends Object

implements DeployableObject, weblogic.deploy.api.internal.Closable

This class is the WebLogic Server implementation of DeployableObject.

WebLogicDeployableObject encapsulates a single module for deployment purposes. A deployment tool uses the constructors for this class to present an application module to the deployer. When the tool is done with this object it is highly recommended that it be formally closed (see close() ). This ensures resources are closed and removes any temporary files that may have been created.

Applications can be part of a parent installation directory. This directory structure has the following organization:

 
 install-root (eg myapp)
 -- app
 ----- archive (eg myapp.ear)
 -- plan
 ----- deployment plan (eg plan.xml)
 ----- external descriptors (eg META-INF/weblogic-application.xml ...)

Method Detail

close

public void close()

Closes application resources and removes temporary files.

Specified by:

close in interface weblogic.deploy.api.internal.Closable

createDeployableObject

public static WebLogicDeployableObject createDeployableObject(File app)
                                                       throws InvalidModuleException,
                                                              IOException

Create a DeployableObject for an application. The object returned implements a DeployableObject, or J2eeApplicationObject if the application is an EAR. This factory method is intended for use when the application is not contained within an installation root directory.

Parameters:

app - is the archive or root directory of the application.

Throws:

InvalidModuleException

IOException

createDeployableObject

public static WebLogicDeployableObject createDeployableObject(File app,
                                                              File appRoot)
                                                       throws InvalidModuleException,
                                                              IOException

Create a DeployableObject for an application. The object returned implements a DeployableObject, or J2eeApplicationObject if the application is an EAR.

Parameters:

app - is the archive or root directory of the application.

appRoot - is application's installation root directory.

Throws:

InvalidModuleException

IOException

createLazyDeployableObject

public static WebLogicDeployableObject createLazyDeployableObject(File app,
                                                                  File appRoot)
                                                           throws InvalidModuleException,
                                                                  IOException

Throws:

InvalidModuleException

IOException

entries

public Enumeration entries()

Returns an enumeration of the module file entries. All elements in the enumeration are of type String. Each String in the returned enumeration represents a file name relative to the root of the module.

Specified by:

entries in interface DeployableObject

Returns:

An enumeration of the archive file entries. An empty enumeration is returned if any IO errors occur.

getChildBean

public DDBean[] getChildBean(String xpath)

Returns DDBeans based on the specified xpath expression, relative to the root element of the primary descriptor of this DeployableObject. Returns null if no DDBeans match the xpath expression.

Specified by:

getChildBean in interface DeployableObject

getClassFromScope

public Class getClassFromScope(String className)

Returns the Class object from this module for the named class, or null if there is no class. The scope is the module itself. This method honors the aplication's manifest class path. For EARs, this provides access to the application level classes only.

Specified by:

getClassFromScope in interface DeployableObject

getDDBeanRoot

public DDBeanRoot getDDBeanRoot()

Returns the root DDBean for this module. If this object was created through SessionHelper.inspect() then it may throw an unchecked RuntimeException indicating parse failures

Specified by:

getDDBeanRoot in interface DeployableObject

getDDBeanRoot

public DDBeanRoot getDDBeanRoot(String filename)
                         throws FileNotFoundException,
                                DDBeanCreateException

Returns a DDBeanRoot object for the named XML instance document. Use this method to return DDBeanRoot objects for secondary deployment descriptor XML instance documents, such as WSDL files or weblogic-cmp-jar.xml. The file may be in either the archive or in the external configuration directory (install-root/plan).

The descriptor will be parsed and a full tree of DDBean's are created.

Specified by:

getDDBeanRoot in interface DeployableObject

Parameters:

filename - The full path name of the XML instance document to return, specified from the root of the module. The path must be either relative to the root of this module, or in the same relative location in the module's external configuration directory.

Returns:

A DDBeanRoot object for the XML data.

Throws:

FileNotFoundException - If the named file cannot be found

DDBeanCreateException - If an error is encountered while creating the DDBeanRoot object.

getDDBeanRoots

public DDBeanRoot[] getDDBeanRoots()

List of DDBeanRoot objects representing all of the known deployment descriptors for this module

getDescriptorBean

public weblogic.descriptor.DescriptorBean getDescriptorBean()
                                                     throws IOException

Typed descriptor bean tree for this modules standard descriptor.

Throws:

IOException

getEntry

public InputStream getEntry(String name)

Returns an InputStream for the given entry name. The file name must be relative to the root of the module.

Specified by:

getEntry in interface DeployableObject

Parameters:

name - The file name relative to the root of the module.

Returns:

The InputStream for the given entry name, or null if not found.

getModuleDTDVersion

public String getModuleDTDVersion()

Deprecated. As of version 1.1, replaced by DDBeanRoot.getDDBeanRootVersion()

A convenience method to return the deployment descriptor document version number of the primary deployment descriptor for this module (for example, web.xml, ejb-jar.xml, ra.xml, application.xml, or application-client.xml.) This method does not return the version number for documents such as webservices.xml and webservicesclient.xml; use DDBeanRoot.getDDBeanRootVersion instead. This method is deprecated. Use DDBeanRoot.getDDBeanRootVersion instead.

Specified by:

getModuleDTDVersion in interface DeployableObject

Returns:

A string that describes the version number of the XML instance document. Null is returned if no version number was found.

getParent

public WebLogicJ2eeApplicationObject getParent()

getText

public String[] getText(String xpath)

Specified by:

getText in interface DeployableObject

Parameters:

xpath - Is an xpath expression relative to root element of this module.

getType

public ModuleType getType()

Returns the ModuleType of the deployment descriptor (for example, the EAR, JAR, WAR, or RAR) that this DeployableObject represents.

Specified by:

getType in interface DeployableObject

toString

public String toString()

Returns a String representation of the module type and archive.
