The cluster only helps when you get into realms beyond the reach of a single machine, and generally where that machine is cpu-bound.

I've rarely worked anywhere where the IT dept competes against itself (it does happen, and I think it's generally a bad thing). In fact, I too am working for clients with their own IT staff. If the IT department has to compete against outside contractors, it _should_ be an uphill battle. I'm bidding on those contracts where I know I have expertise they don't have in-house. I should be able to underbid them, and not waste time experimenting with technologies. Often part of that contract will involve teaching the in-house staff how to maintain the end-product - and next time I may not have the edge in bidding that I had the first time. -- derek - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Exactly my point. When I have worked for corporations, deadlines were set cooperatively. If I said it could be down in a month, and the user said "we need it in two weeks", I told them what they _could_ get in two weeks. If they said "we need it _all_ in two weeks" they had to either forget it or throw more resources at it.

Last time we kicked this around on an HTML discussion forum, we couldn't find a way to obscure, in any way, the actual file "browse" button. There's been significant changes in all the major browsers since then, so things could have changed, but I would doubt any such changes are intentional. If you overlay the browse button with an image, the button doesn't receive the onClick event. There is no way for any other control to click the button programmatically. Similarly, you can overlay the actual filename box, but nothing is permitted to programmatically change the contents of the filename. Yes, you can make it look as if you upload a file while sending just the name (other than by just leaving off the "enctype" attribute) - it's possible to read the contents of the filename box and change another object's value - you just can't write to the filename. You should, however, be able to programmatically submit the form, once the user has filled in the filename, so you can stick an image over that button (but then you could use an image button directly). -- derek - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I don't really see how there could be "native Struts parts", since it's just an extension of Struts, but what I've been using is: , - really simplify layout of row-oriented but non-tabular data input tags - I haven't a clue how it's done, but if they fail validation, the corresponding message is displayed with the input field rather than just using . for collapsing menus I haven't yet used but it looks quite handy for tabular data.

I know nothing about JSF, and tried to get into Velocity and it seemed like just too much work. I think that's really because I got some bad advice, early, but I gave up on it. The responses you've received so far strike me as odd - which makes me think none of the respondents have actually looked at Struts Layout.

I actually agree with all this. I usually use frames. I just didn't agree that you would necessarily get a performance improvement by putting your functions in a frame (and think that any functions that are going to be used throughout an application belong in one or more script files, anyway, regardless of whether they're in the frame that invokes them or in another). -- derek - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I _really_ hope it's doing a better job with tiles definitions. I work mostly with Oracle, and have found JDeveloper to be a really useful tool. So when I recently started using Struts, I used JDeveloper, even though I haven't found any good documentation about using the two together.

I had the same problem last week, and the simplest solution is to make sure you have the latest commons-validator jar. 1.1.3 validates properly against the DTD in the jar file, rather than needing to go to the web. (But thanks for the more detailed explanation of _why_ going to 1.1.3 worked for me, Joe) -- derek - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Presently, Agreed, Reset sets the form values back to their "default" values - if your tag is , then the default value is going to be "zz". The simplest way to do what you want is either to create the tags with blank values, and have javascript that iterates through the form fields and sets the values, or create the tags with the defaults you want and have the javascript set their "...defaultValue='' " I don't think you can do it without Javascript, because defaultValue is a DOM property not a tag attribute . -- derek - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Tiles: using i18n string
Given a tile definition like: and a message that I would normally retrieve like: How can I pass the message to the tile? I realized that in this particular case, it made more sense to invoke the tile using: and have layout.jsp get the message from the key, but I'm sure that's not always the case. It would seem that the beanName and beanProperty attributes of the put tag should come into play, here, but I haven't found a single example of using them. -- derek - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

NMF :-) If folks could manage to keep their version numbers synchronized it would help. It's libcommons-validator-java 1.3-1 (OK, I misread it and typed 1.3.1, where the debian subversion shouldn't have been included, but I don't know why it's given as 1.3 not 1.1.3). > > I would try first seeing if the problem exists with the version of > validator that ships with the version of struts you are using.

I expect that when I get my struts and validator jars in sync with the ones I've downloaded from Debian, the problem will go away - certainly the validator jar in my application dates back to 2003-07, whatever version it really is. -- derek - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Validator : network unreachable
I'm running Validator 1.3.1, Apache 2.0.52, Tomcat 4.1.30, Struts 1.1 on a Debian Linux system. When connected to the net, Tomcat starts fine. When unconnected, I get the following message in catalina*.log. Why on earth does Validator need to reach the web? In the first place, my Tomcat is local and I don't need to go to the web, but I really, really, hate apps that want to make connections I don't know about. Is there something I can do to make Validator work when I'm unconnected, or must I wrote my own validations?
