Bat Deployment (Contd)
Hello,
This question is related to
https://www.experts-exchange.com/questions/22454895/BAT-file-deployment.html
As recommended, I used izPack to deploy my application. Well, it works great, you can just double click on the jar file and it will *extract* the file for you. However, after extracting to the folder that user wants, the user needs to execute the java again by going to command prompt and typed in "java -jar blah blah". Then the question comes again. What would be the best idea to execute the java application?
Hence, in my opinion, izPack only helps you to create a *good* look-and-feel installer. If we can double click on the jar as izPack, why can't we double click on our custom jar file as well?
Any idea?
PS. I will get back on this by tomorrow.
Thanks
David

If you deploy via Java Web Start, you will get a smoother experience

Yes the platform should have the Java 2 Standard Edition (java.exe or javaw.exe) as the default opener for .jar files instead of something else like Winzip.

CEHJ, I agree with you about the Java WebStart but I just would like to straight things out about the izPack at this moment :). I like the idea of being able to double click the jar file - it is very friendly to the users.
objects, mayankeagle,
>>"What OS, Have you tried double clicking the jar"
I used Windows 2000. Well, one thing, izPack is to create installer in the form of jar where you can double click the jar file (installer). Then the installer will extract all the files out to the destination folder. That's all. I can't double click on my jar file that has been extracted out by izPack.
This is my scenario.
I have successfully created the installer with izPack. It extracts out my /lib/*.jar (third party jar) and the /main.jar (my main app jar). After user has extracted out this to (assuming) C:/Program Files/JavaProg/, the user needs to go to the command prompt, go to the C:/Program Files/JavaProg/ and execute the java command manually to run the application.
If izPack can create the double click Jar, can we do the same to our app?
Thanks and please let me know if my explanation is unclear.

Thanks mayankeagle,
>>"You can if the OS is configured to start it using Java 2, if it contains a main class and a corresponding entry in the manifest."
Not sure about this. Can you give me more idea about this? URL should be fine. Currently, when I double click on the my jar file, it says that it could not find the Main class.
Thanks

Means that Java 2 should be defined as the default application to open JAR files. In Windows, goto Windows Explorer -> Tools -> Folder Options -> File Types.
>> when I double click on the my jar file, it says that it could not find the Main class.
That probably means that Java 2 is the default application already. You need to add the JAR file to the classpath or try putting it in %JAVA_HOME%\jre\lib\ext and then double click on it.

Let me try that. So it means that user needs to set their classpath manually. Am I right?

Guess so.... otherwise it might be possible through some script....

Yes, but of course JWS can create a desktop shortcut.
As far as double-clicking your jar is concerned, have you done your manifest properly?

Okay,
The problem comes of the unsupportedClass. I compiled it using jdk 1.6 while try to double click the jar in the jre 1.5. However it still reports the problem as "could not find the Main class."
Well, I think that I am going to have another question on the jdk compatibility soon.
Thanks all for this.

Compile it to as low a target as possible for maximum portability

It is okay CEHJ,
please post it in new thread so anyone can get benefit by it.
