Hi,

I am trying to build my project using ant first time.But i am getting compilation errors though if i manually do it it gets compiled.
The compiler is telling it is not able to find servlet package.


My Development directory structure is:


project1(Directory)
META-INF(Sub-Directory) jspPages(Sub-Directory) WEB-INF(Sub-Directory) index.jsp(page)


In META-INF folder one Manifest.mf file is there
In jspPages folder my jSP pages are there
In WEB-INF following directories are there:

1)lib (In this i have kept the jars which are needed for my application)

2)src (In this another folder namely 'java' is there & inside 'java' folder my src files are there.ALso my build.xml & build.properties file are there in src folder )

3)web.xml


This is my build.xml:





This is my build.properties



Also my classes & dist folders are getting created inside src folder but i want to create in WEB-INF.So how to do it??

Its possibly something to do with the long directory names you use - the spaces can cause problems. Try running Ant with the -verbose flag; this will show you what values properties have and what arguments Ant is using with the javac command. You might be able to spot the problem this way.

I put the servlet.jar in the 'lib' directory in my current development structure as shown above instead of specifying that long path .But then also the compiler is telling that the javax.servlet.* & javax.servlet.http.* package doesn't exist so it's not able to find the classes used from that package.So how to fix this thing??

Is there any error in using that format for specifying the relative directory & context directory that is ../ & ./ Also please tell me the difference between these two signs actually i am confused between them??

Please help me!!

Did you run your build with the -verbose flag?

You define your classpath outside your javac task so you will need to refer to it by reference rather than directly. This:

Tells Ant to tell javac to include the resource "apath" in the classpath, whereas this:

tells Ant to include whatever apath references in the classpath.

../ and ./ behave just as they do from a command window. So ./ == the current directory and ../ == the current directory's parent directory.
