关于允许javabean的问题

Question

大哥bean不需要配置! 是不是你类路径不对啊

Answer 1

可能是我类路径不对。
我的虚拟目录是： d:\webApp
TestBean.java在d:\webApp\WEB-INF\classes\TestBean.java
调用的网页在d:\webApp\Test.jsp可是运行TestBean.jsp后总提示TestBean找不到

Answer 2

这样 你 在classes下加个包 在TestBean.java里定义一下编译后 在看看这样应该好用

Answer 3

我把d:\webApp添加如了ClassPath后，重起Tomcat，现在是这样的提示：org.apache.jasper.JasperException: For input string: "asdf"

Answer 4

好啊！
你有QQ或者msn吗？

Answer 5

加个Package试试看：
myclass.TestBean路径：d:\webApp\WEB-INF\classes\myclass\TestBean.java

Answer 6

晕都说发到你短信里了 msn:joyaga9524@hotmail

Answer 7

现在可以运行了，谢谢大家。
我的源文件是：
package myclass;
public class TestBean
{
private String userName;
private String password;
private int age; public void setUserName(String name)
{
this.userName=name;
}
public void setPassword(String password)
{
this.password=password;
}
public String  getUserName()
{
return this.userName;
}
public String getPassword()
{
return password;
}
public setAge(int age)
{
this.age=age;
}
public int getAge()
{
return this.age;
}
}
第一个错误的发生是我的ClassPath设置的不对。
第二个错误是我在测试的时候最后一个参数应该用数字，而我用了字符串，所以产生了异常。现在好了，谢谢大家！
