Hi, First, if you stick with 4.1, you might want to try 4.1.31 instead of 4.1.27 as it's the latest stable release.
However, I don't think what you're reporting is a bug, and so 4.1.27 vs 4.1.31 doesn't matter for this specific issue. The reason I don't think it's a bug is that webapp initialization order is not guaranteed: it may simply be the context you're trying to get hasn't been initialized yet, so a null return is valid. Your code should be tolerant of it (and defer registration, throw an error, or whatever you want). That also means a Servlet's init method isn't guaranteed to return the context object, because it might be called before the container even starts initializing another webapp. Yoav Shapira http://www.yoavshapira.com >-----Original Message----- >From: Andreas Steffan [mailto:[EMAIL PROTECTED] >Sent: Saturday, November 13, 2004 11:42 AM >To: [EMAIL PROTECTED] >Subject: Bug with contextInitialized using otherServletContext.getContext ? > >Hallo tomcat developers, > >we are using Vignette Application Portal v7.1 on tomcat 4.1.27, and we >are encountering a problem using a ServletContext to obtain a reference >to another one. > >The whole story goes as follows: > >The portal (which is a web-application) is configured in server.xml to >make sure it gets started before the portlet-application.
