Class GenericDeploymentTool
java.lang.Object
org.apache.tools.ant.taskdefs.optional.ejb.GenericDeploymentTool
- All Implemented Interfaces:
EJBDeploymentTool
- Direct Known Subclasses:
BorlandDeploymentTool,IPlanetDeploymentTool,JbossDeploymentTool,JonasDeploymentTool,OrionDeploymentTool,WeblogicDeploymentTool,WebsphereDeploymentTool
A deployment tool which creates generic EJB jars. Generic jars contains
only those classes and META-INF entries specified in the EJB 1.1 standard
This class is also used as a framework for the creation of vendor specific
deployment tools. A number of template methods are provided through which the
vendor specific tool can hook into the EJB creation process.

classpath- the classpath to be used for this build.
-
getCombinedClasspath
Get the classpath by combining the one from the surrounding task, if any and the one from this tool.- Returns:
- the combined classpath
-
log
Log a message to the Ant output.- Parameters:
message- the message to be logged.level- the severity of this message.
-
getLocation
Get the build file location associated with this element's task.- Returns:
- the task's location instance.
-
configure
public void configure(org.apache.tools.ant.taskdefs.optional.ejb.EjbJar.Config config) Configure this tool for use in the ejbjar task.- Specified by:
configurein interfaceEJBDeploymentTool- Parameters:
config- the configuration from the surrounding ejbjar task.
-
addFileToJar
protected void addFileToJar(JarOutputStream jStream, File inputFile, String logicalFilename) throws BuildException Utility method that encapsulates the logic of adding a file entry to a .jar file. Used by execute() to add entries to the jar file as it is constructed.- Parameters:
jStream- A JarOutputStream into which to write the jar entry.inputFile- A File from which to read the contents the file being added.logicalFilename- A String representing the name, including all relevant path information, that should be stored for the entry being added.- Throws:
BuildException- if there is a problem.
-

-
needToRebuild

- boolean indicating whether or not the
jarFileis up to date
-

Returns the Public ID of the DTD specified in the EJB descriptor. Not every vendor-specificDeploymentToolwill need to reference this value or may want to determine this value in a vendor-specific way.- Returns:
- Public ID of the DTD specified in the EJB descriptor.
-
getManifestFile

prefix- the prefix where to llook for the manifest file based on the naming convention.- Returns:
- the manifest file or null if the manifest file does not exist
-
writeJar
protected void writeJar(String baseName, File jarfile, Hashtable<String, File> files, String publicId) throws BuildExceptionMethod used to encapsulate the writing of the JAR file. Iterates over the filenames/java.io.Files in the Hashtable stored on the instance variable ejbFiles.- Parameters:

-
checkAndAddDependants
Add all available classes, that depend on Remote, Home, Bean, PK- Parameters:
checkEntries- files, that are extracted from the deployment descriptor- Throws:
BuildException- if there is a problem.
-
