请问：jdk中有 javax.servlet的package吗？

[caoxiongjun]

如果没有，那怎么得到它呢？

[maimihui]

有啊，怎么会没有呢?我们的jsp网页就是通过这个类来进行编译成为servlet文件的啊!

[j2me_home]

有这个包呀

可是，当我编译一个import javax.servlet.jsp.*;的文件时，
出现了下面的错误：
（classpath=.;C:\j2sdk1.4.2\lib\tools.jar;C:\j2sdk1.4.2\lib\dt.jar;C:\j2sdk1.4.2\lib\classes12.jar;C:\Tomcat 5.0\bin\bootstrap.jar;）

这个是我加上去的，说明一下我的classpath设置．

（classpath=.;C:\j2sdk1.4.2\lib\tools.jar;C:\j2sdk1.4.2\lib\dt.jar;C:\j2sdk1.4.2\lib\classes12.jar;C:\Tomcat 5.0\bin\bootstrap.jar;）

[vincege]

tomcat\common\servlet.jar

[zyx0328]

在J2EE的SDK里，不是J2SE的.
安装好J2EESDK后，把lib下的j2ee.jar设进classpath再试试

[maseccc]

需要在classpath中加入
c:\tomcat5\common\lib\jsp-api.jar
C:\tomcat5\common\lib\servlet-api.jar

谢谢各位，尤其楼上的，问题解决了．

对了，我安的是j2se.
