郁闷了一个星期的strust配置后的启动问题

[ddwwyyll2002]

配置了strust后启动Tomcat时候老是出先异常，
我怀疑是 strust-config.xml和web.xml出错误了，请教高手指点如何配置，

strust-config.xml的配置
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE struts-config PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 1.2//EN"
"http://jakarta.apache.org/struts/dtds/struts-config_1_2.dtd">
<struts-config>
　 <form-beans>
<form-bean name="empForm" type="dw.strust.example.EmployeeForm"/>
</form-beans>

<action-mappings>
<action path="/validateEmployee" type="dw.strust.example.ValidateEmployeeAction" name="empForm scope="request" input="/inputContent.jsp">
<forward name="success" path="/outputContent.jsp"/>
</action>
</action-mappings>

<global-forwards>
<forward name="logon" path="/outputContent.jsp"/>
</global-forwards>
</struts-config>

web.xml 的部分
...
<servlet>
<servlet-name>action</servlet-name>
<servlet-class>
org.apache.struts.action.ActionServlet
</servlet-class>
<init-param>

<load-on-startup>2</load-on-startup>
</servlet>

<servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
..

[sjg008]

初步诊断问题出在web.xml 中的这一句
<!--param-name>application</param-name>
改为
<param-name>application</param-name>

[ddwwyyll2002]

1.
dw.strust.example.ValidateEmployeeAction
在classes\dw\strust\example\下的

2.
我现在已经没有用<bean:message>所以我把
<!--param-name>application</param-name>
<param-value>ApplicationResources</param-value-->注释了

3.
我把web.xml里的
<load-on-startup>2</load-on-startup>
注释了，现在能启动了，

但在打开web页面inputContent.jsp的时候出现
org.apache.jasper.JasperException: /inputContent.jsp(35,6) jsp.error.unterminated.tag
at org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:94)
...
现在我把inputContent.jsp里的所有用的标签都去掉了
就保留
<%@ taglib uri="/html" prefix="html"%>
还是有这个错误，感觉是<%@ taglib uri="/html" prefix="html"%>
错了，但不知道哪里错了。。
请高手帮我分析一下，挽救一个郁闷了一个星期的人，谢谢

[sjg008]

应该是这样
<%@ taglib uri="/WEB-INF/Struts-html.tld" prefix="html" %>
你要保证你的WEB-INF文件夹下有Struts-html.tld文件
以及其他文件

[飞行的兔子]

<%@ taglib uri="/html" prefix="html"%>
将其中的uri和web.xml中taglib中定义的uri写成一致!

[ddwwyyll2002]

我刚刚又多适了几次，
在inputContent.jsp里保留
<%@ taglib uri="/html" prefix="html"%>
<%@ taglib uri="/bean" prefix="bean"%>
<%@ taglib uri="/logic" prefix="logic"%>
<%@ taglib uri="/app" prefix="app"%>
页面能打开了

但是如过一旦加了
<html:text property="name"/>标签
打开页面就出现错误:
org.apache.jasper.JasperException: Cannot find bean org.apache.struts.taglib.html.BEAN in any scope
at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:254)
at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:295)
..
大概意思是不能找到这个org.apache.struts.taglib.html.BEAN 在 any scope
是什么原因呢

而且我把<html:text property="name"/>删了，
改为
<html:form action="validateEmployee.do">
</html:form>
打开页面就出现错误:
org.apache.jasper.JasperException: Cannot find ActionMappings or ActionFormBeans collection
at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:254)
at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:295)
at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:241)

也就是说现在，只要使用了标签就出错，请教各位是什么原因引起的呢？谢谢你们

[飞行的兔子]

<html:text property="name"/>
你有这样的标签的话,你的ActionForm这个bean中一定有一个成员名称是name,这个名称和property是对应的,在提交时,你的这些数据会被control servlet提交到你写的那个ActionForm去组合数据,如果你的表单中的property和那个bean中的成员不对应的话,就会出现问题!
你是否写了ActionForm了

[ddwwyyll2002]

感觉会不会是
struts-config.xml里的配置映射问题?

[ddwwyyll2002]

有两个bean
一个是EmployeeForm:
package dw.strust.example;
import org.apache.struts.action.ActionForm;

/**
* <p>Title: </p>
* <p>Description: </p>
* <p>Copyright: Copyright (c) 2004</p>
* <p>Company: </p>
* @author not attributable
* @version 1.0
*/

public class EmployeeForm extends ActionForm{
private String name = "";
private String department = "";
private String[] skills;

public String getName(){
return name;
}

public void setName(String name){
this.name = name;
}

public String getDepartment(){
return department;
}

public void setDepartment(String department){
this.department = department;
}

public String[] getskills(){
return skills;
}

public void setSkills(String[] skills){
this.skills = skills;
}
public EmployeeForm() {
}
}

一个是ValidateEmployeeAction:

package dw.strust.example;
import org.apache.struts.action.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.ServletException;
import java.io.IOException;
import java.util.List;

/**

* <p>Description: </p>
* <p>Copyright: Copyright (c) 2004</p>
* <p>Company: </p>
* @author not attributable

*/

public class ValidateEmployeeAction extends Action{
public ValidateEmployeeAction() {
}

public ActionForward perform(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException,ServletException{
ActionErrors errors = new ActionErrors();
EmployeeForm empForm = (EmployeeForm)form;

String name = empForm.getName();
if(name.trim().equals("")){
ActionError error = new ActionError("error.missing.name");
errors.add(ActionErrors.GLOBAL_ERROR,error);
}

String department = empForm.getDepartment();
if(department.trim().equals("")){
ActionError error = new ActionError("error.missing.department");
errors.add(ActionErrors.GLOBAL_ERROR,error);
}

String[] skills = empForm.getskills();
if(skills == null){
ActionError error = new ActionError("error.missing.skills");
errors.add(ActionErrors.GLOBAL_ERROR,error);
}

return mapping.findForward("success");
}
}

[飞行的兔子]

你把现在tomcat启动的错误日志和struts-config.xml贴出来看看!

[ddwwyyll2002]

struts-config.xml文件:

<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE struts-config PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 1.2//EN"
"http://jakarta.apache.org/struts/dtds/struts-config_1_2.dtd">

<form-bean name="empForm" type="dw.strust.example.EmployeeForm"/>
</form-beans>

<action-mappings>
<action path="/validateEmployee" type="dw.strust.example.ValidateEmployeeAction" name="empForm scope="request" input="/inputContent.jsp">
<forward name="success" path="/outputContent.jsp"/>
</action>
</action-mappings>
</struts-config>

现在启动没错误了，
就是运行inputContent.jsp页面的时候出先错误
org.apache.jasper.JasperException: /inputContent.jsp(21,5) No such tag test in the tag library imported with prefix html

[ddwwyyll2002]

打错了个字
test->text

但还是提示
Generated servlet error:
[javac] Since fork is true, ignoring compiler setting.
[javac] Compiling 1 source file
[javac] Since fork is true, ignoring compiler setting.
[javac] D:\javaTool\Tomcat 4.1\work\Standalone\localhost\dwtest\inputContent_jsp.java:159: cannot resolve symbol

[javac] location: class org.apache.jsp.inputContent_jsp
[javac] out.print( currentSkill );
[javac] ^
[javac] 1 error

[飞行的兔子]

<html:test property="name"/>
改成<html:text property="name"/>

[ddwwyyll2002]

取掉inputContent.jsp里的：
<logic:iterate id="curentSkill" name="skillsList">
<html:multibox property="skills">
<%= currentSkill %>
</html:multibox>
</logic:iterate>

还是出现这个错误:
org.apache.jasper.JasperException: Cannot find ActionMappings or ActionFormBeans collection
到底是什么原因呢，

[飞行的兔子]

<%= currentSkill %>
改成<bean:write name="currentSkill"/>看看!
你把上面的那行去掉当然不行啊,这样在ActionForm bean中就不能找到和skills对应的property了!

[ddwwyyll2002]

老是出现这个原因怎么搞的啊，郁闷啊
org.apache.jasper.JasperException: Cannot find ActionMappings or ActionFormBeans collection
WEB-INF/lib/下有struts.jar
WEB-INF/classes/下有dw.strust.example.EmployeeForm
和dw.strust.example.ValidateEmployeeAction
WEB-INF/下有struts-logic.tld,struts-bean.tld,struts-html.tld,struts-config.xml
web.xml,app.tld

我现在已经把表单只设置了一个字段了，就一个name
EmployeeForm.java里面就一个name属性:

package dw.strust.example;
import org.apache.struts.action.ActionForm;
public class EmployeeForm extends ActionForm{
private String name = "";

public String getName(){
return name;
}

public void setName(String name){
this.name = name;
}
public EmployeeForm() {
}
}

ValidateEmployeeAction.java也只留下了name判断:
package dw.strust.example;
import org.apache.struts.action.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.ServletException;
import java.io.IOException;
import java.util.List;

public class ValidateEmployeeAction extends Action{
public ValidateEmployeeAction() {
}

public ActionForward perform(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException,ServletException{
ActionErrors errors = new ActionErrors();
EmployeeForm empForm = (EmployeeForm)form;

String name = empForm.getName();
if(name.trim().equals("")){
ActionError error = new ActionError("error.missing.name");
errors.add(ActionErrors.GLOBAL_ERROR,error);
System.out.println("sssss");
}
return mapping.findForward("success");
}
}

哪位大哥救命啊，我不想在郁闷一个星期，谢谢高手和前辈帮忙指点分析，已经很尽力了，，快疯了。。。

[OnlyFor_love]

strust-config.xml的配置中的<action path="/validateEmployee" type="dw.strust.example.ValidateEmployeeAction" name="empForm scope="request" input="/inputContent.jsp">


name后面的值少个引号啊！name="empForm

在web.xml中配置以上这些了吗？？

[OnlyFor_love]

还有标签应该是这样的吧！
<%@ taglib uri="struts/html-el" prefix="html" %>

[jianghuxing]

你的页面在web-info下放着没，我在你的web-info下没有发现那几个jsp页面呀。！！！！！！！！！！11111

[ddwwyyll2002]

彻底郁闷了，现在不知道怎么搞的又好，
开始我还以为是没有
<global-forwards>
<forward name="failed" path="/failed"/>
<forward name="success" path="/success.do"/>
</global-forwards>
而出错的，现在不管加还是去，都对了，
在action 里面+forwrad 也对了，郁闷
<action path="/validateEmployee" type="dw.strust.example.ValidateEmployeeAction" name="empForm scope="request" validate="true" input="/inputContent.jsp">
<forward name="success" path="/outputContent.jsp"/>
</action>
不知不觉自己就好了，~~~~~~
哎。。。。。
谢谢大家，帮助我，真是谢谢你们，，你们都是好人，我爱你们：）
