public class WeblogicDeploymentTool
extends GenericDeploymentTool

The weblogic element is used to control the weblogic.ejbc compiler for generating weblogic EJB jars. Prior to Ant 1.3, the method of locating CMP descriptors was to use the ejbjar naming convention. So if your ejb-jar was called, Customer-ejb-jar.xml, your weblogic descriptor was called Customer- weblogic-ejb-jar.xml and your CMP descriptor had to be Customer-weblogic-cmp- rdbms-jar.xml. In addition, the <type-storage> element in the weblogic descriptor had to be set to the standard name META-INF/weblogic-cmp-rdbms- jar.xml, as that is where the CMP descriptor was mapped to in the generated jar.

Constructor Detail

WeblogicDeploymentTool

public WeblogicDeploymentTool()
Method Detail

addSysproperty

public void addSysproperty(Environment.Variable sysp)
Add a nested sysproperty element.


createWLClasspath

public Path createWLClasspath()
Get the classpath to the weblogic classpaths


setOutputDir

public void setOutputDir(java.io.File outputDir)
If set ejbc will use this directory as the output destination rather than a jar file. This allows for the generation of "exploded" jars.


setWLClasspath

public void setWLClasspath(Path wlClasspath)
Optional classpath to WL6.0. Weblogic 6.0 will give a warning if the home and remote interfaces of a bean are on the system classpath used to run weblogic.ejbc. In that case, the standard weblogic classes should be set with this attribute (or equivalent nested element) and the home and remote interfaces located with the standard classpath attribute


setCompiler

public void setCompiler(java.lang.String compiler)
The compiler (switch -compiler) to use; optional. This allows for the selection of a different compiler to be used for the compilation of the generated Java files. This could be set, for example, to Jikes to compile with the Jikes compiler. If this is not set and the build.compiler property is set to jikes, the Jikes compiler will be used. If this is not desired, the value "default" may be given to use the default compiler


setRebuild

public void setRebuild(boolean rebuild)
Set the rebuild flag to false to only update changes in the jar rather than rerunning ejbc; optional, default true. This flag controls whether weblogic.ejbc is always invoked to build the jar file. In certain circumstances, such as when only a bean class has been changed, the jar can be generated by merely replacing the changed classes and not rerunning ejbc. Setting this to false will reduce the time to run ejbjar.


setJvmDebugLevel

public void setJvmDebugLevel(java.lang.Integer jvmDebugLevel)
Sets the weblogic.StdoutSeverityLevel to use when running the JVM that executes ejbc; optional. Set to 16 to avoid the warnings about EJB Home and Remotes being in the classpath


getJvmDebugLevel

public java.lang.Integer getJvmDebugLevel()

setSuffix

public void setSuffix(java.lang.String inString)
Setter used to store the suffix for the generated weblogic jar file.

Parameters:
inString - the string to use as the suffix.

setKeepgeneric

public void setKeepgeneric(boolean inValue)
controls whether the generic file used as input to ejbc is retained; defaults to false

Parameters:
inValue - true for keep generic

setKeepgenerated

public void setKeepgenerated(java.lang.String inValue)
Controls whether weblogic will keep the generated Java files used to build the class files added to the jar. This can be useful when debugging; default is false.

Parameters:
inValue - either 'true' or 'false'

setArgs

public void setArgs(java.lang.String args)
Any optional extra arguments pass to the weblogic.ejbc tool.


setJvmargs

public void setJvmargs(java.lang.String args)
Set any additional arguments to pass to the weblogic JVM; optional.

Parameters:
args - the arguments to be passed to the JVM

setEjbcClass

public void setEjbcClass(java.lang.String ejbcClass)
Set the classname of the ejbc compiler; optional Normally ejbjar determines the appropriate class based on the DTD used for the EJB. The EJB 2.0 compiler featured in weblogic 6 has, however, been deprecated in version 7. When using with version 7 this attribute should be set to "weblogic.ejbc" to avoid the deprecation warning.


getEjbcClass

public java.lang.String getEjbcClass()
Get the ejbc compiler class


setWeblogicdtd

public void setWeblogicdtd(java.lang.String inString)
Deprecated. Defines the location of the ejb-jar DTD in the weblogic class hierarchy. Should not be needed, and the nested <dtd> element is recommended when it is.

Parameters:
inString - the string to use as the DTD location.

setWLdtd

public void setWLdtd(java.lang.String inString)
Deprecated. Defines the location of weblogic DTD in the weblogic class hierarchy. Should not be needed, and the nested <dtd> element is recommended when it is.

Parameters:
inString - the string to use as the DTD location.

setEJBdtd

public void setEJBdtd(java.lang.String inString)
Deprecated. Defines the location of Sun's EJB DTD in the weblogic class hierarchy. Should not be needed, and the nested <dtd> element is recommended when it is.

Parameters:
inString - the string to use as the DTD location.

setOldCMP

public void setOldCMP(boolean oldCMP)
Set the value of the oldCMP scheme. This is an antonym for newCMP


setNewCMP

public void setNewCMP(boolean newCMP)
If this is set to true, the new method for locating CMP descriptors will be used; optional, default false.

The old CMP scheme locates the weblogic CMP descriptor based on the naming convention where the weblogic CMP file is expected to be named with the bean name as the prefix. Under this scheme the name of the CMP descriptor does not match the name actually used in the main weblogic EJB descriptor. Also, descriptors which contain multiple CMP references could not be used.


setNoEJBC

public void setNoEJBC(boolean noEJBC)
Do not EJBC the jar after it has been put together; optional, default false


registerKnownDTDs

protected void registerKnownDTDs(DescriptorHandler handler)
Description copied from class: GenericDeploymentTool
Register the locations of all known DTDs. vendor-specific subclasses should override this method to define the vendor-specific locations of the EJB DTDs

Overrides:
registerKnownDTDs in class GenericDeploymentTool

getWeblogicDescriptorHandler

protected DescriptorHandler getWeblogicDescriptorHandler(java.io.File srcDir)

addVendorFiles

protected void addVendorFiles(java.util.Hashtable ejbFiles,
                              java.lang.String ddPrefix)
Add any vendor specific files which should be included in the EJB Jar.

Overrides:
addVendorFiles in class GenericDeploymentTool

writeJar

protected void writeJar(java.lang.String baseName,
                        java.io.File jarFile,
                        java.util.Hashtable files,
                        java.lang.String publicId)
                 throws BuildException
Method 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.

Overrides:
writeJar in class GenericDeploymentTool
BuildException

validateConfigured

public void validateConfigured()
                        throws BuildException
Called to validate that the tool parameters have been configured.

Specified by:
validateConfigured in interface EJBDeploymentTool
Overrides:
validateConfigured in class GenericDeploymentTool
Throws:
BuildException - If the Deployment Tool's configuration isn't valid

isRebuildRequired

protected boolean isRebuildRequired(java.io.File genericJarFile,
                                    java.io.File weblogicJarFile)
Helper method to check to see if a weblogic EBJ1.1 jar needs to be rebuilt using ejbc. Called from writeJar it sees if the "Bean" classes are the only thing that needs to be updated and either updates the Jar with the Bean classfile or returns true, saying that the whole weblogic jar needs to be regened with ejbc. This allows faster build times for working developers.

The way weblogic ejbc works is it creates wrappers for the publicly defined methods as they are exposed in the remote interface. If the actual bean changes without changing the the method signatures then only the bean classfile needs to be updated and the rest of the weblogic jar file can remain the same. If the Interfaces, ie. the method signatures change or if the xml deployment descriptors changed, the whole jar needs to be rebuilt with ejbc. This is not strictly true for the xml files. If the JNDI name changes then the jar doesnt have to be rebuild, but if the resources references change then it does. At this point the weblogic jar gets rebuilt if the xml files change at all.

Parameters:
genericJarFile - java.io.File The generic jar file.
weblogicJarFile - java.io.File The weblogic jar file to check to see if it needs to be rebuilt.

getClassLoaderFromJar

protected java.lang.ClassLoader getClassLoaderFromJar(java.io.File classjar)
                                               throws java.io.IOException
Helper method invoked by isRebuildRequired to get a ClassLoader for a Jar File passed to it.

Parameters:
classjar - java.io.File representing jar file to get classes from.
java.io.IOException
