本文导语: Tomcat 4.1 JDK 1.3.02_2 Bean Code package testbeans; import java.util.*; public class bean1 { int answer; boolean success; String hint; int numGuesses; public bean1() { reset(); } public void setGuess(String guess) { n...
Bean Code
package testbeans;

public class bean1 {
int answer;
boolean success;
String hint;

numGuesses++;
int g;
try {
g = Integer.parseInt(guess);

success = true;

Number Guess
Congratulations! You got it.
And after just tries.
Care to try again?
Welcome to the Number Guess game.
I'm thinking of a number between 1 and 100.
What's your guess?
Good guess, but nope. Try .
You have made guesses.
I'm thinking of a number between 1 and 100.
What's your guess?

編譯後的class 文件放在了
C:TomcatwebappsexamplesWEB-INFclasses
和C:TomcatwebappsexamplesWEB-INFclassesnum
JSP放
C:Tomcatwebappsexamplesjspnum
重啓Tomcat
瀏覽此JSP出現錯誤
org.apache.jasper.JasperException: Unable to compile class for JSP..worklocalhostexamples_0002fjsp_0002fnum_0002fbean_00031_0002ejspbean1_jsp_0.java:3: import 中未找到类 testbeans.bean1。
import testbeans.bean1;

1 个错误
請高手指點了

另外，如果你已用
生成了bean的实例，而且又不需要使用bean1 mybean1=new bean1()这样的定义方式，那么
就是多余的
