DDCreator

public class DDCreator extends org.apache.tools.ant.taskdefs.MatchingTask
Builds a serialized deployment descriptor given a text file description of the descriptor in the format supported by WebLogic. This ant task is a front end for the weblogic DDCreator tool.

Fields Summary
private File
descriptorDirectory
The root directory of the tree containing the textual deployment descriptors. The actual deployment descriptor files are selected using include and exclude constructs on the EJBC task, as supported by the MatchingTask superclass.
private File
generatedFilesDirectory
The directory where generated serialised deployment descriptors are placed.
private String
classpath
The classpath to be used in the weblogic ejbc calls. It must contain the weblogic classes necessary fro DDCreator and the implementation classes of the home and remote interfaces.
Constructors Summary
Methods Summary
public voidexecute()
Do the work. The work is actually done by creating a helper task. This approach allows the classpath of the helper task to be set. Since the weblogic tools require the class files of the project's home and remote interfaces to be available in the classpath, this also avoids having to start ant with the class path of the project it is building.

public voidsetDescriptors(java.lang.String dirName)
Set the directory from where the text descriptions of the deployment descriptors are to be read.

param
dirName the name of the directory containing the text deployment descriptor files.

public voidsetDest(java.lang.String dirName)
Set the directory into which the serialized deployment descriptors are to be written.

param
dirName the name of the directory into which the serialised deployment descriptors are written.
