使用javac编译servlet

Question

我想在NetBeans之外编译servlet.我创建了一个简单的Hello World servlet,它产生了这些编译器错误.

import javax.servlet.ServletException;                                                           
                    ^

public class ServletTester extends HttpServlet {                                                 
                                   ^

显然,javax.servlet无法找到包裹.我有javax.servlet.jar一个GlassFish安装,但如果我这样做,javac ServletTester.java -classpath /opt/glassfish3/glassfish/modules/我仍然会得到相同的错误.

手动编译servlet的正确方法是什么？

试试这个:

$ javac -classpath .:/opt/glassfish3/glassfish/modules/javax.servlet.jar ServletTester.java 

请注意,必须完全指定类路径中的JAR文件名.只是他们的包含目录是不够的.也允许使用通配符(由一条评论指定).
