Learning workflow OSWORKFLOW (1)

Due to several projects, I have been troubled by the process, I decided to learn about workflow, and I learned that OsWorkflow is a lightweight and extremely flexible workflow engine (please visit: http: // Www.opensymphony.com/osworkflow, so it is to learn. Torting an afternoon, finally run the coming of Example. My test environment: WinXP Tomcat4.1.30 Oracle8.05 JDK1.4.2. First, download https://osworkflow.dev.java.net/files/Documents/635/4647/ositeflow-2.7.0.zip. After decompression, copy OSWORKFLOW-2.7.0-Example.War to Tomcat's WebApp, start Tomcat, access http://localhost/osworkflow-2.7.0-example, everything is very easy. OsWorkflow provides a variety of persistence mechanisms MemoryStore (Default), Serializables, JDBCStore, OFBIZSTORE, and more. Since the downloaded EXAMPLE is in order to facilitate the initiator to run the program as soon as possible, MemoryStore is used. Oh, the actual system will not let the data stay in memory. Change to JDBCStore to try. 1. Modify Tomcat's Sever.xml, add:

Resource name = "jdbc / mydb" auth = "container" type = "javax.sql.datasource" />

factory org.apache.commons.dbcp.basicDataSourceFactory driverclassname Oracle.jdbc.driver.Oracledriver URL jdbc: Oracle: Thin: @ 127.0.0.1: 1521: Orcl username Oswf password Oswf maxactive 20 maxidle 10 maxwait -1

2, modify web-inf / classes / OSWORKFLOW.XML (red part is modified according to your database) < Property key = "step.id" value = "id" />

/>

3, in Web-INF / CLASSES propertyset.xml 4, modification Osuser.xml under Web-Inf / Classes

OS_USER OS_GROUP OS_MEMBERSHIP USERNAME pASSWORDHASH GROUPNAME USERNAME GROUPNAME java: comp / env / jdbc / mydb OS_USER OS_GROUP OS_MEMBERSHIP USERNAME Passwordhash < / Property> GROUPNAME USERNAME GROUPNAME Java: Comp / Env / JDBC / MYDB <

/ Provider> OS_USER OS_GROUP OS_MEMBERSHIP USERNAME pASSWORDHASH GROUPNAME USERNAME GROUPNAME java :! comp / env / jdbc / mydb <- Authenticators can take properties just like providers.This smart authenticator should work for 'most' cases - it dynamically looks up the most appropriate authenticator for the current Server. -> 5, running the SRC / ETC / DEPL in the download package in SQL-PLUS Oyment / jdbc / oracle.sql 6, start Tomcat 7, OK.
