I had started installing the Netweaver preview package beginning with WAS when I got this error.
ERROR 2005-07-19 15:44:44
<html>The password you entered for user <em>USHYDDAPPU1\j2eadm</em> is too short.<p>The minimum acceptable length is 7 characters.</html>
USHYDDAPPU1 is the name of my computer. I believe j2eadm is the default admin name for the server etc but the fact is that at that point in the installation process I had not filled any values except the location of the JDK.
Thanks for any suggestions
