這是Jboss 的jBPM3.12框架的用戶指南的中文翻譯。我的翻譯風(fēng)格是中英文對照，只翻譯部分我認為重要的，不翻譯簡單的英文，以免浪費你我的時間。 同時，對于其中的部分內(nèi)容，我會在翻譯中做出解釋和寫上我的理解。
Chapter 5. Deployment部署
jBPM is an embeddable BPM engine, which means that you can take jBPM and embed it into your own java project, rather then installing a separate product and integrate with it. One of the key aspects that make this possible is minimizing the dependencies. This chapter discusses the jbpm libraries and their dependencies.
jBPM是一個嵌入式的BPM（業(yè)務(wù)程序管理）引擎。本章討論jbpm庫和它的依賴庫。
5.1. Java runtime environment
jBPM 3 requires J2SE 1.4.2+
5.2. jBPM libraries
jbpm-[version].jar is the library with the core jbpm functionality.是jbpm的核心功能庫。
jbpm-identity-[version].jar is the (optional) library containing an identity component as described in Section 11.11, “The identity component”.
可選的，這個庫包含了身份驗證組件。用于流程的參與者的管理。
5.3. Third party libraries第三方庫
In a minimal deployment, you can create and run processes with jBPM by putting only the commons-logging and dom4j library in your classpath. Beware that persisting processes to a database is not supported. The dom4j library can be removed if you don't use the process xml parsing, but instead build your object graph programatically.
最小的jbpm部署，只需要核心jbpm庫和commons-logging庫，以及dom4j庫到你的classpath中。此時，不支持持久化業(yè)務(wù)程序到數(shù)據(jù)庫。

commons-logging.jar

logging in jbpm and hibernate
|
The jBPM code logs to commons logging. The commons logging library can be configured to dispatch the logs to e.g. java 1.4 logging, log4j, ... See the apache commons user guide for more information on how to configure commons logging. if you're used to log4j, the easiest way is to put the log4j lib and a log4j.properties in the classpath. commons logging will automatically detect this and use that configuration.

A typical deployment for jBPM will include persistent storage of process definitions and process executions. In that case, jBPM does not have any dependencies outside hibernate and its dependent libraries.
典型的jBPM部署包括持久化業(yè)務(wù)程序定義和執(zhí)行的功能。 需要Hibernate
Of course, hibernate's required libraries depend on the environment and what features you use. For details refer to the hibernate documentation. The next table gives an indication for a plain standalone POJO development environment.
下面的表給出了簡單的標準POJO部署環(huán)境需要的第三方庫。
jBPM is distributed with hibernate 3.1 final. But it can also work with 3.0.x. In that case, you might have to update a few hibernate queries in the hibernate.queries.hbm.xml configuration file. For more info about customizing queries, see Section 7.6, “Customizing queries”

The beanshell library is optional. If you don't include it, you won't be able to use the beanshell integration in the jbpm process language and you you'll get a log message saying that jbpm couldn't load the Script class and hence, the script element won't be available.
Beanshell庫是可選的。
