Ant newbie - Compiler Problems

[Vincent Kennedy]

I apologise in advance if this problem is stupidly simple, but I am a newcomer to Ant. I am running Ant 1.2, Jakarta-Tomcar 3.2.1, JDK 1.3, and all this on Win NT. I have modified the sample build.xml file to build a simple servlet. When I run Ant I get the following message     [javac] File to be compiled:     D:\Apache\jakarta-tomcat-3.2.1\webapps\Vince\src\Hello.java       [javac] D:\Apache\jakarta-tomcat-3.2.1\webapps\Vince\src\Hello.java:67: cannot resolve symbol     [javac] symbol  : class ServletException      [javac] location: package servlet     [javac] import javax.servlet.ServletException;     [javac]                      ^   The complier repeats this for each import of the javax.servlet class. It seems that it cant find the javax.servlet package. I have tried pointing my classpath everywhere logical, and through frustration most places illogical - Has anybody any ideas how to solve this?  I suspect that it is some sort of incompatibilty with jdk1.3 - Either that or something so simple that you will all be laughing at me!   Any help would be appreciated.
