I want to copy war file to tomcat web-app directory using NSIS setup. I have successfully installed tomcat and jdk using following script

!define PRODUCT_NAME "App Deploy"
!define PRODUCT_VERSION "1.0"
!define PRODUCT_PUBLISHER "ZippySoft"

SetCompressor lzma

There are no script errors but war file is not getting copied to c drive . How to do it? Also is it possible to identify path to JDK and Tomcat installation using NSIS ?

Sorry if the question is too obvious, I am quite new to NSIS..
