Selective extraction of Files

proy_relisource · 13th January 2006, 14:32

Hi,
My application needs JDK 1.4.2 to run properly. I have bundled a jdk 1.4.2 with my installer. But if at the destination machine a jdk1.4.2 is already installed then i don't want to extract the jdk with the installer. I am able to check if a jdk is already installed or not in the target system but i can not stop copying the bundled jdk when a jdk is already installed on the target system. I have searched this forum and was unable to find any solutions. Any help will be great for me. Thanks in advance.

See Logical Code Structures section of the tutorial. It explains how you can influence the flow of the script.

Thanks Kichik.
I guess i should have tried it before. but i thought that if i use a logical structure before a

code:
File

command, then may be that file won't get packed with the installer. But i was wrong. I guess that was just stupid of me. Anyway, thanks again.
