被osworkflow的数据库配置(mysql)困住了
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
debug= "99" reloadable="true" crossContext="true" verbosity="DEBUG">
prefix="OSWorkflow." suffix=".log" timestamp="true"/>
auth="Container"
type="javax.sql.DataSource"/>
factory
org.apache.commons.dbcp.BasicDataSourceFactory
maxActive
100
maxIdle
30
maxWait
10000
username
root
password
driverClassName
org.gjt.mm.mysql.Driver
url
jdbc:mysql://localhost:3306/osworkflow?autoReconnect=true
2:配置osworkflow.xml(在WEB-INF/classes目录下),内容如下:
value="select count(*) + 1 from os_wfentry"/>
3:增加propertyset.xml(在WEB-INF/classes目录下),内容如下:
4:修改web.xml,内容如下:
>
OSWorkflow Example App
default.jsp
OSWorkflow Example App
jdbc/DefaultDS
javax.sql.DataSource
Container
5:将jboss-j2ee.jar拷贝到tomcat_home/common/endorsed目录下
6:将驱动程序拷贝到tomcat_home/common/lib目录下
7:启动tomcat但是报以下错误
严重: Parse error in application web.xml
java.lang.NullPointerException
