javax.servlet.http does not exist

[unotfish]

编译写好的formaction老是报错：

Tomcat安装目录common\lib\中的jsp-api.jar与servlet-api.jar放到jdk安装目录下\jre\lib\ext\中

CLASSPATH值为
.;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar;%TOMCAT_HOME%\common\lib\servlet-api.jar;%TOMCAT_HOME%\common\lib\jsp-api.jar

[unotfish]

确实是包名写错了

package org.cjea.Struts.example;

import javax.servlet.http.HttpServletRequest;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;

public final class RegUserForm extends ActionForm{

private String logname;
private String password;
private String email;

public RegUserForm(){
logname = null;
password = null;
email = null;
}

public String getLogName() {
return this.logname;
}
public void setLogName(String logname) {
this.logname = logname;
}
public void setPassWord(String password) {
this.password = password;
}
public String getPassWord() {
return this.password;
}
public void setEmail(String email) {
this.email = email;
}
public String getEmail() {
return this.email;
}

public void reset(ActionMapping mapping, HttpServletRequest request)
{
logname = null;
password = null;
email = null;
}
}





package org.cjea.Struts.example;

import javax.servlet.http.*;
import org.apache.struts.action.*;

public final class RegUserAction extends Action
{

public ActionForward perform(ActionMapping mapping,
ActionForm form, HttpServletRequest req,
HttpServletResponse res)
{
String title = req.getParameter("title");
String password = req.getParameter("password");
String email = req.getParameter("email");
/*
取得用户请求,做相应数据库操作，略
*/
}
}

RegUserForm.java 编译通过
RegUserAction.java 编译 miss return statement

在eclipse下为什么不能导入struts包

import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;有错误

[interpb]

报什么错误

[unotfish]

不能解析 org.apache.struts

[unotfish]

ok了, Eclipse工程的lib下导入Struts包

[interpb]

jre\lib\ext 下面的 两个jar 去掉吧

[unotfish]

去掉了jre\lib\ext 下的jsp-api.jar与servlet-api.jar
问题还是存在

[interpb]

struts.jar也要放到classpath

[softboysxp]

TOMCAT_HOME 你设置了么?
TOMCAT的起始目录应该是叫 CATALINA_HOME

[wangpeng8675]

java_home配置了吗？

[terry_yip]

是因为struts.jar没放到项目classes/lib目录下的原因。

[unotfish]

环境变量配置如下:

JAVA_HOME C:\Program Files\Java\jdk1.5.0_02

TOMCAT_HOME C:\Program Files\Tomcat 5.0

path %SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\Java\jdk1.5.0_02\bin;C:\Program Files\Microsoft SQL Server\80\Tools\BINN

CLASSPATH .;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar;%TOMCAT_HOME%\common\lib\servlet-api.jar;%TOMCAT_HOME%\common\lib\jsp-api.jar;C:\Program Files\Tomcat 5.0\webapps\test\WEB-INF\lib\struts.jar

还是不可以

[interpb]

import javax.Servlet.http.HttpServletRequest;
我晕

包名 都写错了

包名都是小写啊 javax.servlet.http.HttpServletRequest

[graybaby]

TOMCAT_HOME C:\Program Files\Tomcat 5.0
改为CATALINA_HOME试试
