I am having a similar issue as the post with the same title by udo.nast. I could not figure out how to add content to orginal post. I am also having trouble with this since upgrading to Java 7 U45. With Java 7 U25 I am able to access one 200E switch and not the other via the web. They are both running 2.6.6c., the difference is that the one that works launches http://<IP>/wt-app.jar and the one that does not work launches http://<ip>/exmgr.jar. Again with Java 7 U45 neither works displaying a certificate error.
Any help on a workaround would be appreciated.

The issue is that the brocade switch embed a very old certificate from Verisign which signature is made with MD2 algorithm.
This weak algorithm is rejected by default on newer JVM. But you can change this setting:
