best programming language for large erp

Well, this is a simple question - what can be better than java?

C# or VB.net will be suitable with Visual Studio 2010

Java is cool but it requires more work.

<<Java is cool but it requires more work.>>
Only place where Java require more work than anything else is when you have to integrate packages given by different vendors. Because, there you have to write an adaptor code (or a glue code), which is not the problem with .Net platform since the vendor of all package is same Microsoft.
Otherwise, I don't think there is anything Java can't do.

In fact, you can run a enterprise server (J2EE app server) on a minimal free of cost linux machine, the same way you will run anywhere else, but for Microsoft you need windows.

'best' is VERY subjective.  There are many variables you need to look at.

For example:
What OS will you want to run on?
What skills do you have in-house?  No need to go with 'X' if you have a bunch of 'Y' programmers.
Web based or OS app?

as we need full project on web .. how is the asp.net 's (with c#  code's ) performance  for huge project ?

With Java you can develop a back end system (business logic tier) and install it on a Linux or Windows or Mac machine to act as your server and then develop front-end interfaces for it either webbased using JSP or desktop based using Swing and this way you have the flexibility of using both at the same time. abas ERP is a german ERP I have worked with and is developed as I mentioned. You can have a look at their architecture available on their website.  

I using Powerbuilder, and swith to PHP-Apache-MySQL-Firebird on my proyects.
