Collections.EMPTY_MAP since JDK 1.3
Hi, in BeanUtils (public static Map describe(Object bean)) the constant Collections.EMPTY_MAP is used. This constant was only defined in JDK 1.3. It would be nice if this could be changed (back?) to using something like public static final Map EMPTY_MAP = new HashMap(); so that people having to deploy to a not yet 1.3 platform can still use struts. Cheers, -hendrik

Thanks John. For now we simply stepped back to b1. But maybe this indicates that your changes should be applied struts, so that we can all benefit from it. -hendrik > Hi Hendrik, > > This is a 'feature' of WTE.

Form tag problem in VAJ 3.5.3 WTE with 1.0b2
Hi, we just downloaded and tried the new beta2 and experienced problems with Visual Age Websphere Test Environement 3.5.3. It seems that it does not allow to remove attributes from a request, which is apparently done by the form tag. Does anybody else have this problem? To me it seems like a bug in WTE.

jo! + struts
Hi, maybe it's of interest to someone. Because I fixed some bugs, jo! now seems to work quite nicely with struts. To install, create the dir %JO_HOME%/webapp/host/ (if it does not already exist) and drop the wars from the struts webapps directory in there. Then start jo! That should be it. For those of you, who have never heard of jo! before: jo! is an open source and free webserver implementing servlet api 2.2 and jsp 1.1. You can get it at http://www.tagtraum.com/ If there are any problems with struts, please let me know directly => [EMAIL PROTECTED] Cheers, -hendrik - - - - - - - - - - - - - - - - - - - - - - - - - - - tagtraum industries http://www.tagtraum.com/ jo! small&smart 2.2 servletengine Java Server & Servlets The web-application book The WebApp Frameworkhttp://www.webapp.de/

RE: Is Struts with Websphere that slow ? - any other problems?
hi, are there any major problems with websphere and struts? I am especially interested in known problems with WAS AE 3.5.2 on Solaris. Thanks, -hendrik
