Try these commands using tomcat, place your servlet source in src folder and run these,
使用 tomcat 尝试这些命令，将您的 servlet 源放在 src 文件夹中并运行这些，
C:\Documents and Settings\ssit>cd C:\src
C:\src>javac -classpath "C:\Program Files\Apache Software Foundation\Tomcat 6.0\
lib\servlet-api.jar" MyServlet.java
you can get the class file for the servlet. After getting the class file make the war file.
您可以获取 servlet 的类文件。获得类文件后制作war文件。

javac -classpath /home/coolhunk/JBoss/jboss-6.0.0.Final/common/lib/jboss-servlet-api_3.0_spec.jar -d helloapp.war/WEB-INF/classes -sourcepath src/com/manning/jbia/intro/*
The problem is the last item. The wildcard causes it to be expanded into everything in the directory, which causes everything after the first expansion to be treated as a source file name. The expansions also appear to include src/com/manning/jbia/intro/HelloWorldServlet.java~, which the compiler doesn't want to know about.
问题是最后一项。通配符使其扩展为目录中的所有内容，这导致第一次扩展后的所有内容都被视为源文件名。扩展似乎还包括编译器不想知道的 src/com/manning/jbia/intro/HelloWorldServlet.java~。
Try this:
尝试这个：
javac -classpath /home/coolhunk/JBoss/jboss-6.0.0.Final/common/lib/jboss-servlet-api_3.0_spec.jar -d helloapp.war/WEB-INF/classes -sourcepath src src/com/manning/jbia/intro/*.java
