Java applet doesn't show up

[alexbaat]

Hi,

Since a month I'm using the Jfileupload for my customers for uploading files. However a lot of customers are complaining because they don't see the Java applet. It doesn't appear at all and the customers don't get any error.

I tried it myself on multiple pc's and browser and I don't have the problems.

Does anyone have an idea how to solve these problems?

Which JRE version are they using? JRE 1.6.0_19 (or higher)?
