Re: GenericDataSource Enhancement
Except that the javax.sql.DataSource API still includes this method signature, so we need to do something. I guess it would probably be better to return a "not implemented" exception of some sort, then just return a "regular" connection like it does now. Yes or just a normal connection that the user auto closes when he calls close, so won't be pooled or anything. What should be done is testing the isClosed() method before given the Connection to the request. If the database closes the connection will the connection.isClosed() return a boolean true then? My experience has been that this is not sufficient. You don't find out that the driver connection got closed until you try to submit an SQL statement for execution -- what we need to be able to configure is a very low-overhead SQL call that can be tried before returning the connection to the user. What about a extra rollback() call right before given it back to the request? Or is the driver/connection smart enough that the rollback doesn't do anything (because nothing happend) and it doesn't send it to the server? johan

HTML tag library
Did we decide to rename the FORM tag library as the HTML tag library in a 1.0 timeframe? I agree it makes sense, the library has outgrown just forms, but it seems to break my existing late-model JSPs. Worked on the third, now not. We've been assuring people for several weeks that the code-breaking changes were complete. Or, is there a top-level way we can get the JSP's to use the HTML lib instead without editing them all? The change is not mentioned in the release notes, and I didn't see anything here; at first I thought it was a new library that would hold additional non-form tags. If we have some other non-form tags in mind (image, et cetera), I would suggest we leave the form library as it is, and introduce a new HTML library (since the form library is big enough), where both libraries would support the :html, :base, :link tags, and tags on an interim basis. I would also consider moving the bean:message, logic:interate, and logic:redirect tags to a HTML library. Of course, this becomes a discussion of procedural versus functional cohesion, and reasonable people can disagree. In any event, seperate HTML and Form libraries does seem to have higher cohesion to me, since some people might want to use the HTML tags without the rest of it. Incidentally, I note the JAR has jumped in size a bit this week. Was that the addition of the bean property options, or something else?

RE: PLEASE PRETTY PLEASE HELP ME
I had a similar problem with tomcat...
Having looked at your classpath setting.i find struts.jar being set
in the classpath..struts.jar file needs to be in the lib directory
of your web application i.e. /web-inf/lib.. only.
I removed struts.jar from my class path and had it only in the lib
folder.
This actually solved my problem.

RE: PLEASE PRETTY PLEASE HELP ME
The condurum is that you need STRUTS.JAR in the classpath when building
struts applications, but it must not be in the classpath while running
Struts Web Applications. This is because Tomcat can get confused about
which STRUTS.JAR to use.
So, if you are building and testing on the same machine, then the
solution is to use a tool like ANT to add Struts to the classpath
dynamically. But it should not otherwise be on the classpath of the
machine serving the Struts application. (Too many cooks!)

Initializing a Struts application
I'm a little confused about how to best initialize some application scope information in a Struts application. For example, I need to configure a handful of IP addresses which my beans need to talk to. I might do something like this in a configuration file: marketData=127.0.0.1 My question is where to put this information. If I were writing a normal servlet application I would probably define this in the init operation. One option I've considered is to subclass from ActionServlet and add my own custom initialization tags which I can use in my web.xml file. What I'm trying to figure out is how to best initialize a set of application scope variables for my struts application. Any suggestions would be appreciated. Thanks.

I would also consider moving the bean:message, logic:interate, and logic:redirect tags to a HTML library. Of course, this becomes a discussion of procedural versus functional cohesion, and reasonable people can disagree. What does logic:iterate have to do with rendering HTML? Nothing. Likewise for bean:message. Such general purpose tags are needed no matter what kind of output you are producing. logic:redirect does not render any output either -- it relies only on the fact that you're running over an HTTP protocol. If you add it to the HTML tag lib, you're going to need to add a copy of it for XHTML, for WML, for . because you need the functionality anyway. In any event, seperate HTML and Form libraries does seem to have higher cohesion to me, since some people might want to use the HTML tags without the rest of it. That's guaranteed to break backwards compatibility (because the tags have always been in a single TLD). Incidentally, I note the JAR has jumped in size a bit this week. Was that the addition of the bean property options, or something else? Yes -- the org.apache.struts.taglib.html package was added (haven't yet removed the org.apache.struts.taglib.form package which is now redundant). Craig

RE: HTML tag library
I was just wondering if the group has considered naming the html form tags in the same way as their corresponding html tags are named. That is, has this naming convention been considered and ruled out: use struts-form:input type="text" ... for input type="text" ... use struts-form:input type="button" ... for input type="button" ... use struts-form:input type="checkbox" ... for input type="checkbox" ... use struts-form:input type="radio" ... for input type="radio" ... use struts-form:input type="file" ... for input type="file" ... use struts-form:input type="hidden" ... for input type="hidden" ... use struts-form:input type="password" ... for input type="password" ... use struts-form:input type="radio" ... for input type="radio" ... use struts-form:input type="reset" ... for input type="reset" ... use struts-form:input type="submit" ... for input type="submit" ... use struts-form:select ... for select ... I think this might make it easier to write a tool that automates the conversion of html pages (from the graphic artists) to jsp pages. It would also determine the names of future struts tags that render future html tags. Perhaps there's a way to have it both ways, so that existing jsp's are supported. Dan
