使用的是ww2+spring+hibernate3
applicationcontext.xml如下

<!doctype beans public "-//spring//dtd bean//en" "http://www.springframework.org/dtd/spring-beans.dtd">

<!-- add your spring beans here -->

//-----------------
web.xml如下
<?xml version="1.0" encoding="iso-8859-1"?>
<!doctype web-app public "-//sun microsystems, inc.//dtd web application 2.3//en" "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<display-name> acme corp </display-name>
<!-- start snippet: example -->
<filter>
<filter-name> webwork </filter-name>
<filter-class> com.opensymphony.webwork.dispatcher.filterdispatcher </filter-class>
</filter>
<filter-mapping>
<filter-name> webwork </filter-name>
<url-pattern> /* </url-pattern>
</filter-mapping>
<listener>
<listener-class> org.springframework.web.context.contextloaderlistener </listener-class>
</listener>
<!-- end snippet: example -->
<welcome-file-list>
<welcome-file> index.jsp </welcome-file>
<welcome-file> default.jsp </welcome-file>
<welcome-file> index.html </welcome-file>
</welcome-file-list>
<taglib-uri> webwork </taglib-uri>
<taglib-location> /web-inf/lib/webwork-2.2.4.jar </taglib-location>
<!-- end snippet: taglib -->
<resourcelink name="jdbc/datasource" global="jdbc/datasource" type="javax.sql.datasourcer"/>
</web-app>
//--------------------
homedaobject.java如下
package com.ww2.common.dao;
import org.springframework.orm.hibernate3.support.hibernatedaosupport;
import com.ww2.common.pojo.catalog;
public class homedaobject extends hibernatedaosupport implements homedao{
public catalog getcatalogbyid（integer id){
return （catalog)this.gethibernatetemplate（).load（catalog.class, id);
}
}
//--------------------------
出现的现象是，如果使用 <bean id="homedaoproxy" class="org.springframework.transaction.interceptor.transactionproxyfactorybean">
那么工程在启动的时候，就抛出cannot create jdbc driver of class '' for connect url 'null'异常。
把这个事物代理注释掉，则正常。使用的是tomcat5.5
