Re: [jug-discussion] MS Access / Filemaker like front-end for MySQL/Oracle?
Jumping into this conversation. a little late, but... :) I'm not sure how much detail, etc. you need, but open office v2 includes Openoffice Base, which is an MS Access-ish program. I haven't played with it much. By default, it uses hsqldb to create databases, but, like access, you can connect to pretty much any db (mysql and oracle, as well). It'll let you create forms, reports, queries, etc. Again, I haven't used it much so I can't really vouch for quality or ease of use, but it might be worth checking into.

Re: [jug-discussion] Why Jython, or Jelly, or Groovy, or Beanshell or ... instead of perl, or sh script?
I think the issue is that the developer doesn't have remote access to the box; he can only get at the logs through the web. So, scp and rsync are out. wget isn't, of course. :) If it were me... I'd do it in bash using wget. Seems like it would be a one-liner, since you can do it in one line w/ wget, but I'd still throw it in a bash script just so I didn't have to go re-read the man pages on wget every time, and so I didn't have to remember the url, etc. Of course, as pointed out, it all depends on what you're comfortable with. I spend a lot of time in the shell, and have done a fair amount of shell scripting (more than perl scripting, in any event), so... :) Robert Duffy Gillman wrote: Timo - Consider me puzzled. There is something missing in the spec for this project - what is the developer trying to do, simply get the log files? If so then rsync, wget, or scp from the commandline, or a gui-based scp tool seem much more useful than any sort of programming solution. Ok, so barring that, I think this seems a perfect use of a scripting language - either perl or any of the various *sh variants. Perl will give you handy, high-level file processing features that will allow the script to zip through a file (even in a .tgz) with very little coding. *sh variants will have similar chunky, high-level features (between tar, find, grep and ls and a few pipes I think there is a simple solution). Either can be readily incorporated into Apache, and with a slight bit more trouble, into your favorite servlet container or (god forbid) IIS. So really the question becomes, what is the developer comfortable with? In terms of professional development I'd say everyone should have some scripting language under their belt. If the fellow has to depend on Java to do the task I'd hazzard to guess he'll spend 3-4 times longer on the solution. If that is the soultion he has to fall back on, send him home with a copy of the Larry Wall Perl book (O'Reilly Press - wtf's the name? Perl in a Nutshell?), or a printout of 'man bash' (though this assumes he has some facility with the cadre of shell commands he'll need - cat, grep, find, tar, ls, ...) and tell him to grind on the solution a bit longer than he would have in order to get the script going in scripting language. Dollars to doughnuts, I bet it pays off in time savings the next time he's confronted with a data crunching task. -Duffy - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I'm guessing you're referring to command-line linux, which (mostly) boils down to learning the shell of your choice (default tends to be bash; which also happens to be my personal favorite shell these days... although csh can be nice to work in). If this is what you need to learn, I suggest Unix Power Tools (O'Reilly) by Jerry Peek, Tim O'Reilly, and Mike Loukides. Get the 2nd edition, rather than the 3rd edition. You can pick it up online for cheap (I think my copy was two bucks). Reasons why I like this book: 1) It's designed for people on the go. That is, you can pick it up and open it randomly and read a section, learn some cool tidbit, and not worry about what came before or what comes after. That said, it is arranged in a fairly logical fashion such that you /could/ read it from cover to cover. 2) It's hyperlinked. =) Anytime you see a command, there will be a [xx.xx] next to it, giving you the chapter and section with a tip about that command. (In fact, in addition to page #'s on the bottom of the page, there are section numbers at the top of every page.) 3) It's well written: it's concise without losing clarity. 4) They cover the major shells, pointing out differences in behavior where applicable, and they also cover the major *nixes. It isn't strictly a linux book; the knowledge gained will be generally applicable on most unix systems. 5) Something for everyone; whether you're an old hat on *nix, or novice, there's going to be something in the book you didn't know before (or, knew once upon a time, but forgot. =) Robert - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

[jug-discussion] java + openoffice?
Hey gang. I'm wondering if anybody has any experience generating openoffice documents 'on the fly' in java? Good? Bad? Ugly? From what I've seen so far... it's overly complicated (hm... are all things sun this way? =). It would seem that you have to have an instance of openoffice running somewhere that your java app can connect to. The instance acts as a service provider from which you can grab a desktop instance, and from the desktop instance, create documents, etc. However... the developer guide is 1000+ pages long, so... if anybody has worked with this before and has some pointers, I'd sure appreciate them. =) TIA.

[jug-discussion] NIO
Two things 1) Wanted to make a correction/clarification to something I said last night about blocking/non-blocking I/O. in nio, sockets and pipes may be placed in non-blocking mode, but file channels (channels are the nio paradigm for dealing w/ i/o... sorta like a stream, but cooler =) may only be placed in blocking mode 2) I mentioned an article I found to be useful and said I would dig up the URL. http://www.onjava.com/pub/a/onjava/2004/09/01/nio.html?page=1 I don't agree with everything he says. Namely, I don't know that a thread-based model /really/ is more simple than a multiplexed I/O approach. His 3 month experience seems to me to be a result more of unfamiliarity with multiplexed I/O than anything else; coming from a background where multiplexed I/O concepts were already familiar, it took me 3 weeks to learn the relevant portions of nio, implement and test the client and server, and put it into use. The synchronization headaches I avoided more than made up for any multiplexed I/O complexities I had to deal with. ;) Related sites: (Fairly short) TSS thread discussing the article http://www.theserverside.com/news/thread.tss?thread_id=28488 (There are a couple of links in the thread that look promising if you're interested in learning more about general multiplexed i/o, regardless of language) Another decent article on multiplexed i/o, using nio: http://www-106.ibm.com/developerworks/java/library/j-javaio/ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

[jug-discussion] Next week's meeting
So, for the meeting next week, Warner has asked me to present on Tapestry. I have a few ideas on how I'd like to do the presentation, but would like some feedback as to what people would be most interested in. * I have a couple of (more-or-less) completed tapestry projects that I could show, to display various aspects of tapestry * I could just drone on about the various facets of tapestry, and provide code-snippet examples * I'm seriously contemplating putting together a simple object model, and then building a simple webapp using tapestry, from scratch (more or less) during the presentation. * Other ideas not listed here. Thanks for any feedback! Robert - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: [jug-discussion] signed applets + konqueror or opera...
Actually, the applet functions correctly/as expected on Mozilla/Netscape, as well as IE. It's opera and konqueror that have the problems. In fact, Opera for windows functions as expected, so, it's specifically opera for linux (7.11) and konq. that have the problems. They're completely ignoring the fact that it's a signed applet, and not giving the user /any/ opportunity to accept /any/ permissions. They skip the plugin route, and use the jre/jvm directly, which seems to be at the core of the issue (there are several different problems going on, and they are /exactly/ the same in both browsers... png image reading/manipulation, for example). Anyway... I've found a workaround for the most critical portion of the applet; it's about 10x slower than the fileio requiring algorithm I originally wrote, but, it works, at least. Thanks again for any thoughts. Robert Todd Ellermann wrote: My experience with this is maybe 6-7 years old now, but it used to be that IE was one single applet security request for all services. IE file access, printing etc... Where Netscape was ask for one service at a time, type security model. Clearly a one service at a time model is much more robust and secure but alas, we know who won the browser war. Have no idea if those differences still exist today, but they may explain what your seeing. -Todd President PHXjug.org 602-738-6187 - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
[jug-discussion] signed applets + konqueror or opera...
Hi folks... I've got a (self) signed applet; runs fine in mozilla/netscape and IE 5.x or better. While running the gamut of browser tests, I noticed that konqueror(v3.2.2) and opera (v7.11) don't pop up the expected trust this applet? dialog; they just start running. But, when it comes time to perform any permission requiring action (writing data to a temp file), they throw security exceptions. Google turned up other people with the same problem, but no answers. (cf: http://forum.java.sun.com/thread.jsp?forum=63thread=228422tstart=30trange=15 ) Anybody else had to work around this before? Any ideas on directions to head? TIA.

Re: [jug-discussion] Webapp frameworks
Erik Hatcher wrote: Robert, I'll keep this relatively brief, and hopefully pragmatic. No one web framework is *the* one for all situations. The size of your project needs to be taken into consideration as well as the talent of your team and what kind of flexibility the end users demand. If you care about sticking to standards and having tool support is important, then getting on board with JSF may be the way to go. If you want to be able to hire any Joe Blow Web Developer off the street, then Struts is a good way to go. If you have a big project that demands tons of component reuse then Tapestry is a great solution. If very nice testability is needed, the only one I know of that makes this trivial is WebWork2. Heck, if all you have is a couple of pages and not many forms to deal with, JSP's and servlets make a great solution. No matter which way you go, I think it is important to understand the foundation of all Java web frameworks and getting very familiar with servlets and filters, and the capabilities of JSP's - this helps evaluate the other frameworks at least, and helps know what the container provides that all the other frameworks build upon. All that being said and echoing my previous comment that actions speak louder than words... we chose Tapestry and are very pleased with it. So pleased in fact that I immediately weaseled my way into being a committer on the project and am speaking about it around the country starting in a couple of weeks, including a tutorial at OSCON this summer. Erik Thanks for the brief overview. ;) I'm certainly not unfamiliar with the underpinings of servlet/jsp development, as I've been doing quite a bit of it over the last two years... but, until recently, I haven't explored frameworks; I jumped into a servlet based project because that's what my job needed me to do... and they needed the application adjusted, tuned, etc. At the time, revamping this entire application from model 1 to model 2 would have been out of the question... but now that many of the immediate demands (features, fixes, etc.) have been met, I'd like to refactor it such that it's cleaner, more adaptable, and easier to expand in the future. Hence, my research into frameworks. Initially, I was looking at struts, primarily because this particular project may be incorporating portions of another project in the future which already uses struts. But, as I've worked with struts on some other, smaller projects to get a feel for it, I've run into my own share of... issues; suffice it to say that I'm not convinced that it's the framework for me... at least not for this project. Anyway, I appreciate all of the input from everyone. I've certainly got my research/reading cut out for me. ;) Robert - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Tim Colson wrote: Robert wrote: suffice it to say that I'm not convinced that [Struts is] the framework for me... at least not for this project. It's kind of funny to me. Two years ago at JavaOne, Craig McClanahan and Struts seemed to be the talk of the show. I'm in the minority, but I'm not a fan of JSP. So our groups initial selection of Struts 2 years ago (of which I played a role) was not all roses. Well, I suppose I'm in the minority with you. ;) I'm not a big fan of jsp's, either, although jsp 2.0 seems to be a step in the right direction. After working with the Velocity Tools sub-project to help replace the JSP view layer completely with Velocity, I don't find Struts to be all that bad. There are still missing pieces of functionality, or bits that I wouldn't want Struts to provide anyway. Some of us are looking at Servlet Filters and Listeners to provide some of the functionality we want - but decoupled from the controller framework. I'm also looking forward to more info on Spring. Timo P.S. Tapestry seems interesting, as does the template mechanism for HTML, but I dig Velocity... and I dig being able to write non-xml-ish templates. I'm hoping maybe Drew has a bit of time (or somebody else in another meeting) to show off some working Tapestry stuff. Always good to keep an open mind. :-) Tapestry is definitely looking promising for me. I've spent the day looking it over, and I'm liking it a lot... the templating system really is quite neat. Still... I like working with velocity templates, myself... ;) My main issue here is that I'm looking at refactoring a webapp that was originally written model 1 style into mvc. This webapp is currently in the vicinity of about 20,000 lines of code (nearly 40 servlets, and yes, it /is/ a royal pain to maintain; and no, I wasn't the original designer. ;) I'd rather spend more time now doing some research on what framework would really be appropriate to use in this case than just jump in and find out 10,000 lines into refactoring that framework X really isn't the best tool for this particular job. ;) I'm not saying struts is or isn't... I'm just saying i'm not yet sure that it is... so I'm researching. ;) Anyway, I appreciate all the feedback/comments I received; they've given me a lot of good resources to look at, read, etc. Robert - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
[jug-discussion] HttpSession question...
Recently, somebody proposed an interesting question to me which, though I'm pretty sure I know the answer, I've been unable to verify. So, I decided to turn here to see if someone with more wisdom than I had an answer. ;) My understanding of HttpSessions is that, unless you specifically write something to a cookie, the only thing stored on the client side is the sessionID (either via a cookie or via URL rewriting). However, if I do a session.setAttribute(someattr,someobject), that object is simply stored (typically in memory, though not necessarily) server side, available in the web application context. Correct so far? In other words, session attributes are not directly editable client side... right? I mean, this makes complete sense to me, as the client in a web app really doesn't give a hoot about foo or bar, it just wants html. However, someone made a claim to me recently that some information stored as a session attribute could be alterred directly by the user, client side, and therefore posed a security risk to a particular application. Any thoughts? Thanks for the help on this... I've looked over the javadocs, etc., and while they don't say anything to negate my viewpoint, they also don't say anything specifically to validate it.

Re: [jug-discussion] HttpSession question...
That's what I was thinking... but I wanted to bounce it off someone to make sure I wasn't going crazy. ;) Thanks for the validation. =) Robert Chad Woolley wrote: I think you are right, otherwise the J2EE spec would be insecure by definition. A *request* attribute can be changed just by appending it as a URL parameter, but that is really just another name for a form field. Maybe that is what they are thinking of.

[jug-discussion] Struts
Hi, all. I've been looking into incorporating struts into an existing webapp I have responsibility for. For a variety of reasons, I'm interesting in using Velocity for the view layer, rather than jsp, but I'm finding something of a... lack of online documentation regarding the integration. I was wondering if anyone could recommend a good book on struts development in general (or, am I better off to save my money and just use the online doc + java docs? ;), and I'm particularly looking for a book that discusses struts + velocity... I've found two thus far, Struts in Action (Ted Husted) and Profession Struts Development. Anyway, before I go fork out the cash, I was wondering if anyone here had any opinions on these or other reference materials?
