Hi, with tomcat comes the admin-Context. When you use it and select the 'View All Context'-Button you get an IllegalArgumentException. The error arises because of the use of the class org.apache.tomcat.util.RequestUtil in the ContextAdmin-class which is used by the ContextAdmin-JSP. In tomcat 3.2.2 and 3.2.3 the RequestUtil-class throws the Exception when a '/' is URL-encoded in the Parameter-String (explained in the release-notes of 3.2.3). This happens e.g. in lines 76 and 92 of ContextAdmin.java. A quick solution is to use java.net.URLDecoder.decode() instead of RequestUtil. But this class was introduced in JDK 1.2, so users of older JDKs don't have this solution. I'm using 1.3, so the quick solution works fine for me :) If someone is interested in the diffs, I could send them, but they are very simple. If tomcat should run on JDKs prior to 1.2, I could write a small function in ContextAdmin, which translates the '/' before sending it to the RequestUtil-class and send the diffs of this.
