I am using Tomcat 4.1.27 and i am having application outside tomcat directory.I gave the following code in server.xml.

<Context path="/develop" docBase="H:\Sure\develop" debug="0" reloadable="true" crossContext="true" />

I am not getting the above error till i make any changes in java file and compile it(i.e web-inf\classes in my application directory).Why i am getting this error?.
Help me please...

Am I correct that you can access the servlet and get the expected result after Tomcat has been restarted, and you only get the 503 if you change the class files while it is running?
Do the log files show anything related to the servlet?

There is a well-known class-reloading bug in TC 4.1.27. The hotfix is available from: http://apache.mirrored.ca/jakarta/tomcat-4/binaries/
