Harshal,
"Error=2" from Windows means "file not found". You can find the full set of
all of the Windows error codes at
http://msdn.microsoft.com/library/?url=/library/en-us/debug/base/system_error_codes.asp?frame=true.
You have either misspelled the name of the file or, more likely, you have
failed to specify the correct path to the file. Double-check the spelling of
both the "dir" and "executable" parameters to see if they are exactly
correct.
I see that your "dir" parameter is missing the drive letter, colon,
backslash and maybe a directory level or two before 'tomcat4.1'; if you put
the rest of the path there, you may find that your exec task works fine.
Then again, maybe not. I just tried starting Tomcat on my computer via an
Ant task that was written the same way as yours, only I put the full path in
the 'dir' parameter; it didn't work and I got "error=2", just like you. So,
if fixing the parameters along the lines I suggested don't work, choose one
of the following two approaches:
[Approach 1]
<property name="tomcat.path" value="D:\jakarta-tomcat-4.1.24\bin"
description="The path to the startup script."/>
<property name="start" value="startup.bat" description="The name of the
startup script."/>
<target name="start_tomcat" description="Start Tomcat.">
<exec executable="${tomcat.path}\${start}" os="Windows XP"
failonerror="true" description="Starting Tomcat."/>
</target>
[Approach 2]
<property name="tomcat" value="D:\jakarta-tomcat-4.1.24\bin\startup.bat"
description="The path to the startup script."/>
<target name="start_tomcat" description="Start Tomcat.">
<echo message="Starting Tomcat...."/>
<exec executable="${tomcat}" os="Windows XP" failonerror="true"
description="Starting Tomcat."/>
</target>
One of those two approaches should work for you. There may be other
approaches that will work too.

=====================================================================
The line 82 is-->
<exec dir="tomcat 4.1\bin" executable="startup.bat"/>.
Can anyone please tell me how to find a solution for this Exception as
I can only write very simple java programs and as such my knowledge of
JAVA is limited.
Thanks Harshal
