编译 Servlet 库时 Javac 出错 [英] Javac erroring out when compiling Servlet libraries

问题描述

我正在使用 ubuntu，并且我已将路径设置为以下内容:

I am using ubuntu and I have set my paths to be the following:

JAVA_HOME=/usr/local/jdk1.6.0_24
export CLASSPATH=/usr/local/tomcat/lib
export JAVA_HOME

我认为这会将 servlet 库放在编译路径中，但我仍然收到如下编译错误:

I thought that would put the servlet libraries in the compile path, but I am still getting compile errors like this:

package javax.servlet does not exist
    [javac] import javax.servlet.ServletException;

任何想法如何解决这个问题或我做错了什么?通用 Java 库似乎运行良好.

Any ideas how to fix this or what I am doing wrong? The general Java libraries seem to be working fine.

推荐答案

对于 jar 文件，仅指定包含 jar 文件的目录是行不通的.您有两个选择:

With jar files, simply specifying a directory containing jar files will not work. You have two options:

1. 在 CLASSPATH 上单独指定每个 jar 文件:

1. Specify each jar file individually on the CLASSPATH:

export CLASSPATH=/usr/local/tomcat/lib/servlet-impl.jar:/path/to/another.jar

由于您使用的是 Java 6，您应该能够使用 通配符(包含目录中的所有 jar):

Since you're using Java 6, you should be able to use wildcards (to include all jars in a directory):

export CLASSPATH=/usr/local/tomcat/lib/*
