i do not know if java is better than perl.

Both Java and Perl are fine languages, that have proven their merits. I do expect though that you'll get a lot of biased replies - but considering the place you ask, that's what you expect.

I think that if you have to ask here whether Java or Perl would be better, you have already lost the case. When choosing a language to develop an application in while being employed, there's a lot more that matters than whether language X is more suited than language Y.

Standards are good, because that favours interchangability. That's why companies prefer to limit the amount of languages they use; because the more languages they have work written in, the more different abilities they need to hire.

What all i think i will use.the purpose is to make the tool as well as learn more perl.

I guess that "learning more Perl" is your own private goal, and it's not the companies goal to have you learn Perl with this project, otherwise, they wouldn't say you need to do it in Java. The fact that you state such a goal makes me think you haven't quite mastered Perl yet - and this weakens any argument of shorter development times that you could use.
