Need of including ant.jar in classpath for java task
Hi all,
I am new to Ant. I have some questions.
1. Is it necessary to add ant.jar to classpath of java task to run a program
which uses one ant class. Why Ant by default do not include ant.jar and
other libraries in ANT_HOME\lib directory.
2. Is it possible to disable checking for duplicate classname by javac task.
I think this error is given by Ant.
An off topic question too. Can any one suggest me a way to use Outlook
Express to get replies to this mail only. Where is an archive which provides
following by thread and good searching capability. I looked at a site and
its searching capability is very poor.
rgds

Which causes many more problems as well. Ant's timestamp checking
won't work for them, for example.

So you must not compile the classes from separate physical directories
at the same time. Use one <javac> per directory instead.

Re: Need of including ant.jar in classpath for java task

I will give more information on what I am trying to do. I am changing
Tomcat's JspC.java file(Not Ant jspc task). My purpose is to use Tomcat JSP
compiler(JspC.java) to compile all jsp files to work directory then use
javac task to compile these in to classes. My observation found that when
Tomcat compiles jsp files all jsp files are put in the package
org.apache.jsp irrespective of whether it is in a subdirectory or not. These
generated java files are put in the same directory order as jsp files are
residing in the webapp context. Thus a jsp file in the directory
myhost\jsp\index.jsp will be put in a package named org.apache.jsp and put
in the directory jsp in Tomcat work directory. This means all the generated
java servlet files will be in package org.apache.jsp and their physical
locations do not follow the package name. If I compile these files using a
javac task like this it will say duplicate class. The core part of javac
task is given below
<javac fork="true" srcdir="${jspc.base}" destdir="${jspc.base}"
optimize="off" debug="on" failonerror="false">
Any help is appreciated.

If I run a DOS batch file which goes to each directory and compiles files in
each directory it is not complaining about duplicate class name. Definitely
it is in each directory a new process is compiling files. Is there any such
option available with Ant which says to create a new process for each
directory and compile files.

So you can include your own version of DOM classes for example
(without having Ant interfere).
You can use <presetdef> if you think the default behavior is wrong.

I don't think it is Ant doing this. Can you give us an example?

I use MARC <http://marc.theaimsgroup.com/?l=ant-user&r=1&w=2>, there
may be others.
