Applications Overview of Application Assembly and Deployment

24-8 Oracle Complex Event Processing Developers Guide com.bea.wlevs.example.helloworld_1.0.0.0.jar Consider using a similar naming convention to clarify which bundles are deployed to the server. See the Apache Ant documentation at http:ant.apache.orgmanualCoreTasksjar.html for information on using the jar task or the Java SE documentation at http:java.sun.comjavase6docstechnotestoolswindowsjar .html for information on using the jar command-line tool. 11. If your application depends on foreign stages, see Section 24.2.3, Assembling Applications With Foreign Stages .

24.2.2.1 Creating the MANIFEST.MF File

The structure and contents of the MANIFEST.MF file is specified by the OSGi Framework. Although the value of many of the headers in the file is specific to your application or business, many of the headers are required by Oracle CEP. In particular, the MANIFEST.MF file defines the following: ■ Application name—Specified with the Bundle-Name header. ■ Symbolic application name—Specified with the Bundle-SymbolicName header. Many of the Oracle CEP tools, such as the wlevs.Admin utility and JMX subsystem, use the symbolic name of the bundle when referring to the application. ■ Application version—Specified with the Bundle-Version header. ■ Imported packages—Specified with the Import-Package header. Oracle CEP requires that you import the following packages at a minimum: Import-Package: com.bea.wlevs.adapter.defaultprovider;version=11.1.1.4_0, com.bea.wlevs.ede;version=11.1.1.4_0, com.bea.wlevs.ede.api;version=11.1.1.4_0, com.bea.wlevs.ede.impl;version=11.1.1.4_0, org.osgi.framework;version=1.3.0, org.springframework.beans.factory;version=2.5.6, org.apache.commons.logging;version=1.1.0, com.bea.wlevs.spring;version=11.1.1.4_0, com.bea.wlevs.util;version=11.1.1.4_0, org.springframework.beans;version=2.5.6, org.springframework.util;version=2.0, org.springframework.core.annotation;version=2.5.6, org.springframework.beans.factory;version=2.5.6, org.springframework.beans.factory.config;version=2.5.6, org.springframework.osgi.context;version=1.2.0, org.springframework.osgi.service;version=1.2.0 If you have extended the configuration of an adapter, then you must also import the following packages: javax.xml.bind;version=2.0, javax.xml.bind.annotation;version=2.0, javax.xml.bind.annotation.adapters;version=2.0, javax.xml.bind.attachment;version=2.0, javax.xml.bind.helpers;version=2.0, javax.xml.bind.util;version=2.0, com.bea.wlevs.configuration;version=11.1.1.4_0, Assembling and Deploying Oracle CEP Applications 24-9 com.bea.wlevs.configuration.application;version=11.1.1.4_0, com.sun.xml.bind.v2;version=2.0.2 ■ Exported packages—Specified with the Export-Package header. You should specify this header only if you need to share one or more application classes with other deployed applications. A typical example is sharing an event type JavaBean. If possible, you should export packages that include only the interfaces, and not the implementation classes themselves. If other applications are using the exported classes, you will be unable to fully undeploy the application that is exporting the classes. Exported packages are server-wide, so be sure their names are unique across the server. The following complete MANIFEST.MF file is from the HelloWorld example, which extends the configuration of its adapter: Manifest-Version: 1.0 Archiver-Version: Build-Jdk: 1.6.0_06 Extension-Name: example.helloworld Specification-Title: 1.0.0.0 Specification-Vendor: Oracle. Implementation-Vendor: Oracle. Implementation-Title: example.helloworld Implementation-Version: 1.0.0.0 Bundle-Version: 11.1.1.4_0 Bundle-ManifestVersion: 1 Bundle-Vendor: Oracle.
