I don't want to give up my CME quotes. I can't use the IB demo unless I download the sun java. But when I load the sun java, my cme quotes don't work. Also, with the sun java, my tradesignal charts are very slow to load. Am considering IB, but not if I have to use sun java. Any solutions? (I am not very computer smart.)
Believe it or not your network card actually can interefere with java operation. I was using a Linksys PCI card and crashed every time the IB TWS app started. I switched cards and now it works fine. That may be your problem.
I would stick with Java 1.3.1 until another version of 1.4 comes out. 1.4 has some serious bugs abounding in it, I can hardly run it on several of my machines. TWS seems very flaky under it too. http://java.sun.com/j2se/1.3/download.html Also, some one pointed out to me that there are a few sites with Java that require the MS Java VM (Java 1.1) as opposed to the sun one (1.1, 1.2, 1.3 and 1.4). I don't know if your CME applet requires it, but I do know that TWS requires the Sun one (TWS requries Java 1.3 or greater I believe).
