Subject Re: problem with exec task
Date Sun, 05 Feb 2006 22:44:30 GMT
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
