scripting in java

Posted on 2002-04-12
Last Modified: 2010-03-31

I want to hook scripting facility in my java application

for example the user can select a node in a Jtree
and select "import" (a pop up menu option)
this should save the information
in a file on the local drive

Now the user can select "export" (a pop up menu option)
this should read the file and create the appropriate node in the tree

The user can change these files any time
How do I prevent the user from putting any junk in these

Do I need to look into a scripting language
or there could be a simpler approach

Please let me know your views

> How do I prevent the user from putting any junk in these

 The simple answer is that you cannot prevent them. It would be like trying to prevent someone of entering a non-existing e-mail address. You cannot know until you send an e-mail.

  A more complicated answer is: it depends on what you define as "junk". The simplest solution I can think of is to have a filter that parses the data and filters out all this you define as junk.

> Do I need to look into a scripting language
or there could be a simpler approach

  You could if you wanted to but it would be better (and easier) to stick with pure Java. At the end of the day there are so many APIs (if you do not like the standard ones you can still use third-party ones) that it is more convenient to be done with Java.

  Hope it helps.

IS there any link or help on this

I found a couple of things like "Rhino"
but am not sure how is it applicable in thi scenario

If I stick with pure java how do I achieve this
could you just describe the framework for this

Thanks a ton.

I really don't see this as a double posting. The contents of the question might be close but:

- This Q is two weeks older than your other question!

- I think that girionis has already given a valid comment on this question and it would be unfair not giving him a chance here. You never provided any feedback for him.

differently and posted it again

But since I have got some direction from him I am accepting his comment as an answer

Thanks again
