求解

[解决办法]
对于tomcat5.0 配置数据源的时候要求在server.xml中进行修改加上例如：

<DefaultContext reloadable="true" crossContext="true">
<Resource name="jdbc/juddiDB" scope="Shareable" type="javax.sql.DataSource"/>
<ResourceParams name="jdbc/juddiDB">
<parameter>
<name>url</name>
<value>jdbc:mysql://localhost/juddi</value>
</parameter>
<parameter>
<name>driverClassName</name>
<value>org.gjt.mm.mysql.Driver</value>
</parameter>
<parameter>
<name>username</name>
<value>root</value>
</parameter>
<parameter>
<!--帐号密码根据数据库安装配置修改-->
<name>password</name>
<value>******</value>
</parameter>
</ResourceParams>
</DefaultContext>

这样的代码。

但是对于tomcat6.0.16的版本，配置数据源一般不修改server.xml，而是在context.xml中对数据源进行相应的配置，如：

<Resource name="jdbc/juddiDB" scope="Shareable" type="javax.sql.DataSource"
maxActive="100" maxIdle="30" maxWait="10000"
username="root" password="root" driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/juddi"/>

不然配置不对，可能会报tomcat版本错误
