SSH:Servlet action is not available 苦闷数日。

Question

初学SSH，就遇到了很多人都遇到的问题。我是照着李兴华老师的智囊团项目弄得，在第一个注册页就出现了这个问题各种百度，Google都没法得以解决有说配置文件错的，有说JAR包冲突的。日志文件如下：2009-5-10 11:20:27 org.apache.catalina.startup.HostConfig checkResources

Answer 2

项目没有成功启动，原因是Name jdbc is not bound in this Context，
应该你没有配置名叫jdbc的数据源

Answer 3

这是server.xml的配置。。  <Logger className="org.apache.catalina.logger.FileLogger"
 prefix="localhost_MysqlTest_log." suffix=".txt"
 timestamp="true"/>
 
<Context path="/known" docBase="E:\MyKnownProject\MyKnownProject\WebRoot"
debug="5" reloadable="true" crossContext="true">
  <Resource name="jdbc/known"  auth="Container" type="javax.sql.DataSource"/>

<ResourceParams name="jdbc/known">

</parameter>
<parameter>
<name>url</name>
<value>jdbc:mysql://localhost:3306/known</value>
</parameter>
  </ResourceParams>
</Context>

Answer 4

这是spring.xml<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">

class="com.lyp.known.dao.impl.IUserDAOImpl">
<property name="hibernateTemplate">

</property>
</bean></beans>

Answer 5

这是struts-config.xml....<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd"><struts-config>

</struts-config>

Answer 6

server.xml里的jdbc配置去掉，统一在spring的配置文件里配置！

Answer 7

这种配置也要在web.xml进行配置的
<resource-ref>
<description>DBConnection</discription>
<res-ref-name>jdbc/know</res-ref-name>
<res-type>java.sql.DataSource</res-tye>
<res-auth>Container</res-auth>
</resource-ref>
