ActiveBpel的啟動是隨TOMCAT的啟動而開始的,下面用TOMCAT啟動時控制臺的信息為藍(lán)

本,分析ActiveBpel啟動的裝載步驟:

1)進(jìn)入org.activebpel.rt.tomcat.AeProcessEngineServlet的init方法
2004-9-13 15:08:20 org.activebpel.rt.tomcat.AeProcessEngineServlet init
信息: Active BPEL startup

2)讀取配置文件,開始啟動bpel引擎
2004-9-13 15:08:20 org.activebpel.rt.tomcat.AeProcessEngineServlet

startOrUpdateBpelEngine
信息: Loading engine config from D:\tomcat5.0/bpr/aeEngineConfig.xml

3)啟動一個掃描器,默認(rèn)每10秒掃描一次指定目錄,如果有新的流程定義,則自動將它發(fā)

布;啟動掃描器的同時,發(fā)布WEB應(yīng)用
2004-9-13 15:08:31 org.apache.catalina.core.StandardHostDeployer install
信息: Installing web application at context path /bpel_example_client_page

from URL file:D:/tomcat5.0/webapps/bpel_example_client_page
2004-9-13 15:08:31 org.apache.catalina.core.StandardHostDeployer install
信息: Installing web application at context path /jsp-examples from URL

file:D:\tomcat5.0\webapps\jsp-examples
2004-9-13 15:08:31 org.apache.catalina.core.StandardHostDeployer install
信息: Installing web application at context path? from URL

file:D:\tomcat5.0\webapps\ROOT

信息: Installing web application at context path /tomcat-docs from URL

file:D:\tomcat5.0\webapps\tomcat-docs

4)大約隔了10秒,發(fā)布AeEngineAdmin.bpr流程
2004-9-13 15:08:32 org.activebpel.rt.tomcat.AeProcessEngineServlet

createBprDeployment
信息: Deploying new ActiveBPEL deployment

file:/D:/tomcat5.0/bpr/AeEngineAdmin.bpr

5)發(fā)布bpel_example.bpr流程
2004-9-13 15:08:33 org.activebpel.rt.tomcat.AeProcessEngineServlet

createBprDeployment
信息: Deploying new ActiveBPEL deployment

file:/D:/tomcat5.0/bpr/bpel_example.bpr

6)發(fā)布bpel_example_web_services.bpr流程
2004-9-13 15:08:34 org.activebpel.rt.tomcat.AeProcessEngineServlet

createBprDeployment
信息: Deploying new ActiveBPEL deployment

file:/D:/tomcat5.0/bpr/bpel_example_web_services.bpr

7)BPEL引擎啟動完成.
