Error when installing on server

[Tristan Van Poucke]

Ive just installed my jsp / servlet site on the server I bought and I get this weird error :

HTTP Status 500 - Internal Server Error

what could this mean?

[William Brogden]

Possibly a Java version or library version conflict?
Which version of Java did you use to compile - same as is on server?
What is the source of LayoutBuilder?

I have already solved this problem.
My mistake was , I uploaded the files using Ascii instead of binary. This made all sorts of Internal server error's appear.

Thanks anyway.

Friendly regards.
