osworkflow的mysql数据库配置

时间:2011-01-16

今天研究了一下osworkflow,想运行一下他的例子程序看看效果。结果在配置与数据库连接方面出了问题,郁闷至极。

我用的是mysql数据库,按照

http://www.opensymphony.com/osworkflow/1.3%20Running%20the%20Example%20App.html一步一步的配置。

我的配置文件具体如下:

1:在tomcat的conf目录下修改server.xml,增加以下内容

<Context path="/osworkflow_example" docBase="osworkflow-2.7.0-example" debug= "99" reloadable="true" crossContext="true" verbosity="DEBUG"> <!-- debug level is set to paranoid, to know what is happening, turn it off once you do not need it --> <Logger className="org.apache.catalina.logger.FileLogger" prefix="OSWorkflow." suffix=".log" timestamp="true"/> <!-- put log4j.jar into: TOMCAT_ROOT/webapp/osworkflow-2.7.0-example/WEB-INF/lib if you want to use it for logging --> <Resource name="jdbc/DefaultDS" auth="Container" type="javax.sql.DataSource"/> <ResourceParams name="jdbc/DefaultDS"> <parameter> <name>factory</name> <value>org.apache.commons.dbcp.BasicDataSourceFactory</value> </parameter> <!-- <parameter> <name>factory</name> <value>org.apache.catalina.users.MemoryUserDatabaseFactory</value> </parameter> --> <!-- Maximum number of dB connections in pool. Make sure you configure your mysqld max_connections large enough to handle all of your db connections. Set to 0 for no limit. --> <parameter> <name>maxActive</name> <value>100</value> </parameter> <!-- Maximum number of idle dB connections to retain in pool. Set to 0 for no limit. --> <parameter> <name>maxIdle</name> <value>30</value> </parameter> <!-- Maximum time to wait for a dB connection to become available in ms, in this example 10 seconds. An Exception is thrown if this timeout is exceeded. Set to -1 to wait indefinitely. --> <parameter> <name>maxWait</name> <value>10000</value> </parameter> <!-- MySQL dB username and password for dB connections --> <parameter> <name>username</name> <value>root</value> </parameter> <parameter> <name>password</name> <value></value> </parameter> <!-- Class name for mm.mysql JDBC driver --> <parameter> <name>driverClassName</name> <value>org.gjt.mm.mysql.Driver</value> </parameter> <!-- The JDBC connection url for connecting to your MySQL dB. The autoReconnect=true argument to the url makes sure that the mm.mysql JDBC Driver will automatically reconnect if mysqld closed the connection. mysqld by default closes idle connections after 8 hours. --> <parameter> <name>url</name> <value>jd
