I am successfully making and thoroughly debugged various java programs using Jbuilder 2005 and I am hoping to turn this into a business by selling my compiled programs over the net as downloads. But what I don’t know is what I must do to a compiled java program so that it is made into an executable form of a download that can be sent over the net.

A client must be able to download my application from the net (from a website I have yet to set up) to their desktop and then when they double click the icon for it on their desktop, just like when you double click any other icon on your desktop, this simply automatically causes the application to open and run. But I have no idea of how the desktop ’knows’ what program it must run when an icon is double-clicked. Obviously I don’t want a client to have to open any IDE like Jbuilder to run it nor do I want the client to have to run it by explicitly using any command prompt.

Aren’t many applications sold over the internet as downloads written in java byte-code? If so, surely it must be possible for me to make such a download, isn’t it? If any one give me a few pointers (or even websites) on how to do this I would be most grateful.

Hi,
JBuilder has an option to make a java application into an executable application [exe] or in to an executable jar file, user just need to double click on it. If you go through the JBuilder help, you will find how to do it.

I went to help|help topics|deployment in Jbuilder. I look under the deployment section and I found what is says very difficult to understand. I am new to this and I didn’t know what a jar file was until I looked it up I a book. I am not sure what I am doing but I tried to make a jar file of a project called jarDownload by making this the current project and then by going to file| new…|archive in Jbuilder. I then select one of the archive types to make an archive. The archive type I chose was ‘Application’ -is this the correct choice for my purpose?
I then kept clicking ‘next’ without changing any default properties and then I finally clicked ‘finish’ and a new symbol appeared in the top-left pane of Jbuilder named ‘Application’ so I assumed that I had succeeded in making a jar file. But then when I did a search on the hard disk for a file called jarDownload .jar , according to the search , no such file exists! But even if I found such a jar file, I would not know what I should do with it. What would the next step be? Can anyone tell me the proper way to make jar files for my purpose?

Thanks for that.
I now will perform some long and very careful reading of this link.
