Challenging Ques:Adding files into the Installed Jar

[MananW]

Hi All

I have developed an application in java where I provide data files as well inside the Jar.
Now for updating my application, I want to add files in that Data folder i.e. I want to add new files in that folder and all other things will remain same.

Does anybody know how can I achieve this.

Thanks in Advance,
Manan

Hi Manan,

AFAIK it's not possible to add files to your deployed JAR, unfortunately. I do not know which device you are using but if it implements the FileConnection API (JSR-75) you can use it to read new files from the filesystem...

I hope it helps!

But if the device does not have JSR-75 then does it mean that we cant add anything into that Jar.

Means we cant provide update and hence we cant develop good application on J2ME.Are you trying to say this.................................

Is there any Work Around without JSR-75???????

Hi Manan,

In order to add new files without JSR-75 you'll need to package the application again including the new/modified files and redeploy it.

You should consider a lot of strategies as workarounds, e.g, you can change your strategy and retrieve information from a backend database that gets updated as per your needs. Do think about other options if this one is not good for you, ok?

Hi,

the think is that the whole application(jar file) will be updated.
