Just pull any list of "America's 10 largest companies". The companies on the list may vary depending on whose list you use, but essentially, any major company is going to have a significant JEE investment, except for maybe Microsoft.
Some major reasons for that include
1. IBM and Sun are big JEE supporters, and big corporations tend to rely heavily on IBM and Sun
2. JEE has a well-earned reputation for delivering where security and scalability are critical.
3. If you're big enough, you're likely to be running a little of everything. JEE, .Net, Python, Perl, FORTRAN, COBOL - you name it.
Customer surveys are for companies who didn't pay proper attention to begin with.

Why did you use "may be" here in case of Microsoft. I thought Microsoft does not favour JEE and similarly Sun does not favour .NET.
Microsoft must not be using Java in any of their projects...
It's true that American politics have gone pretty insane on the subject of ideological purity, but so far at least, American businesses are a little more pragmatic. It was sort of an open joke for a long time that Hotmail was hosted on BSD Unix because they couldn't keep it running on Windows servers. Chances are good that Microsoft is running SAP, and I think SAP's preferred programming language is Java. IBM has been trying to evict Windows for years from internal use, but as a consulting company, they have to maintain a certain level of contact with Windows just because their customers do. Likewise for Sun, which additionally provides Windows applications like OpenOffice and even Java itself.
While I do know of one very large company right here in my own home town that was crazy enough to suffer with no software at all when they couldn't get it from IBM, one reason why companies like IBM, Microsoft and Sun dominate the world is because while they may prefer to "eat their own dog food", they do have the sense to use whatever they can as long as it doesn't actually give them a PR liability.
