This is not inconsistent with the previous statement. It is an enhancement of it. JSP fragments that are complete pages may be named with .jsp or .jspf and may be placed in the jspf folder or with other static content. 2) I agree that JSPs should generally go with other static content.

For someone with Java (or C#) experience, I'd also recommend Koenig and Moo's Accelerated C++, because it quickly jumps into writing good clean modern maintainable C++ code, practically from page 1, making heavy use of the STL and some of those algorithms you've found little use for. == 2 of 3 == Date: Wed, Dec 8 2004 1:05 pm From: James Kanze Rene wrote: > James Kanze <[EMAIL PROTECTED]> wrote: >>Well written C++ isn't necessarily difficult, but it is different from >>Java.

Perl makes C++ look like a model of simple elegance and readability. On the other hand, while Perl is significantly less readable than if average C++, it probably contains less traps for the unwary than C++. You might characterize Perl as a write only language -- it's not that difficult to get a somewhat working application, but God help the poor soul who has to read and understand it. Whereas C++ tends to other direction -- a well written C++ program can be a joy to read, but there are quite a few little things you have to know and to pay attention to to get there. And to get back on topic, I'd rate Java between the two, albeit much closer to C++ than to Perl. Well written Java is quite readable -- not as much as C++, but still, not bad. And while Java is lacking in many of the more basic things you need to write really robust applications (e.g. static linking, so you can test what your customer actually runs), things like garbage collection and a well designed set of libraries do mean just that much less that the programmer has to do. -- James Kanze home: www.gabi-soft.fr Conseils en informatique orientée objet/ Beratung in objektorientierter Datenverarbeitung 9 pl.

Garbage collection no, you do have to think about lifetime of object issues at the design level, as part of the design. In Java, most of the time, your work stops there. A quick evaluation, just to be sure that garbage collection IS adequate, and no real code to write, except in the exceptional cases (somewhere between 5% and 10%) where it for one reason or another, you do need determinist disposal. In C++, when you've handled the design aspects, your work has just started. BUT... if you get the design aspects right (which you should be doing in Java as well), most, if not all of the extra work is just grunt work -- it doesn't require much thought, and while it often requires more code than one would like, C++ does have several techniques, such as destructors, which make it actually superior to Java when you need determinstic disposal. >> It's a far cry >> from having garbage collection, and it IS one more thing you have to >> think about, but since at the conceptual level, you have to be concerned >> with lifetime of object issues anyway, it usually ends up to be just one >> more implementation detail.

It depends. Some of the containers have iterators which allow arithmetic which behaves somewhat like pointer arithmetic. All of those containers also support indexation, however, so once again, you're not obliged to do stupid things if you don't want to. When it comes down to it, of course, neither C++ nor Java can be taken as models with regards to their collections and iterators. C++ uses really stupid names, like ++ and *, rather than a simple, understandable next() and element() (or something along those lines), but that's just a naming convention. Java combines access and incrementation, which is very constraining, and not at all nice. But C++ takes the cake by requiring two iterators -- try using one function to determine the range that you want to pass to another function, and you'll pull your hair out. What I really don't understand in all this, of course, is that most pre-Java and pre-STL libraries used pretty good, straightforeward iterators -- like those described in the GoF Design Patterns book, for example, or those in the OSE C++ library. Given that we knew well how to do it before the STL or Java, it's hard to understand the design decisions in these libraries. (The Java Collections, in fact, implement the iterators in the USL C++ library almost exactly. Something that C++ users knew was a mistake as early as 1990.) Still, if you are going to learn C++, you probably have to count on investing a bit of time learning the STL. And THAT isn't easy. There are alternatives, like the OSE library, but they aren't widely used, and as a beginning C++ programmer, you probably won't be able to impose them on your employer. (I have yet to succeed in imposing them, and I'm far from a beginner when it comes to C++.) >> It's been ages (something like fifteen years) since I've used a null >> terminated character string in C++ other than at a C interface.

Sorry. Today, of course, std::string is pretty much standard. I don't know of a compiler which doesn't support it, and I don't know of any new code which doesn't use it. Before around 2000, of course, this wasn't so true. But I've still never seen a C++ application which didn't use some sort of String class. Historically, it was the first class you wrote; even today, a simple String class is a good exercise for a value oriented class. Think of it from a Java point of view. If the language didn't provide java.lang.String, would you really use Char[] with a '\0' terminator? Or would you write your own String class? >> > Fourth: Learn the containers in STL as soon as practically possible, >> > especially <map> and <list>. >> Regretfully, I'll agree.

Real support for STL has only appeared in the last few years, so if the code base goes back some, they more likely have some third party library, or their own. And if they have their own, you'll find real resistance to the STL, even if their own is worse (and believe me, I've seen lots worse that the STL). On the other hand, one of the major motivations today for taking on new C++ programmers is to acquire knowledge of these new techniques. Personally, at the application level, I"ve yet to find the slightest use for template meta-programming (although it's fun -- very intellectually challanging), and I find the STL a disaster. But... good knowledge of the two will almost certainly land you a job. >> In practice, I'd say that you do have to >> know the tradeoffs with regards to the containers (vector, deque and map >> are the ones I use most often -- almost never list).

Perkins" Hey everybody - I'm wondering if anyone's ever seen this issue before. I'm sending plain SMTP emails in a JSP (on WebSphere 4) using JavaMail 1.3.2, and the messages are being received with no body. Below is the basic gist of the block of code sending the emails. I know some things may look funny (specifying the SMTP server address in Transport.connect() rather than in the Properties object passed to the Session constructor, etc)... but I had some weird issues getting the app to resolve to the right mailserver box, and this is the version of code we came up with that actually results in emails being sent: Session mailSession = Session.getDefaultInstance(new Properties();, null); MimeMessage mimeMessage = new MimeMessage(mailSession); mimeMessage.setFrom(new InternetAddress("[EMAIL PROTECTED]")); InternetAddress[] address = InternetAddress.parse("[EMAIL PROTECTED]", false); mimeMessage.setRecipients(Message.RecipientType.TO, address); mimeMessage.setSubject("Test @ " + new Date().getTime()); MimeBodyPart mimeBodyPart = new MimeBodyPart(); mimeBodyPart.setText("This is a\ntest\n"); Multipart multiPart = new MimeMultipart(); multiPart.addBodyPart(mimeBodyPart); mimeMessage.setContent(multiPart); mimeMessage.setSentDate(new Date()); Transport transport = mailSession.getTransport("smtp"); transport.connect("mail.myserver.com", null, null); transport.sendMessage(mimeMessage, mimeMessage.getAllRecipients()); I know that the version of JavaMail shipping with WebSphere 4 is older than 1.3.2, and this newer JAR may be unsupported and causing compatibility issues. To be safe, we'll be reverting back to the out-of- box configuration when the environment is rebuilt this evening. However, my gut still tells me there has to be something else in play. Has anyone else seen this issue before, and/or have any thoughts on what the solution may be?

If /servlet/MyServlet is served at the same hostname as the page you're redirecting from, for example if you're redirecting from http://abc.def.org/some.jsp to http://abc.def.org/servlet/MyServlet, then you can do this: response.sendRedirect("/servlet/MyServlet") otherwise you need to include the full URL. -- JustThe.net Internet & New Media Services, http://JustThe.net/ Steven J.

I know this has been a real pain in the a%*& to you guys but it has been extremely helpful to me. Now, I know what I need to do to go forward with this project. I fully expect to be running into roadblocks like this from time to time before I can call myself a web site developer but I believe it will be well worth it in the end. I want to thank both of you for the time and effort you have both put in one this. It has been helpful.

Actually, if he is counting on using Java to implement CGI scripts, he's found one of the few application areas where it is relevant. (Of course, one could question the reasonableness of such a choice, given the presence of JSP.) > If you are not a troll, then your least worry is the speed of running a > contrived hello world example, it is more like getting much more basic > fundemental understanding about practical programming. > if you are just trolling just stop. There are applications where start-up time is important. I have a couple of small programs that I invoke from the editor to filter part of the text -- typically just a couple of lines; JDK's start up time pretty much makes Java a no runner here. There are other applications where it isn't, but other things in Java implementations make the language inappropriate. And of course, there are other applications for which it is really the only reasonable alternative -- I'm certainly not going to write CGI code in *any* language if I can use JSP. For most large scale applications, of course, the performance of the language simply isn't an issue these days. -- James Kanze home: www.gabi-soft.fr Conseils en informatique orientée objet/ Beratung in objektorientierter Datenverarbeitung 9 pl.

Typically I was given a test and then later I would have to justify my answers. Most the companies that didn't probe me much or were thrown when I actually had a lot of questions about how they do their job got written off. The company I now work at seems to use your methodology.

Am I wrong? While looking for a new job I talked a lot with others. Someone also brought up the fact that job descriptions were too restrictive. Someone noted that if a company wanted to hire a foreign employee they would take the employees resume, create a job description that matched the resume PERFECTLY then wait for all the residents of that country to fail. After a period of time the company could then claim they tried to hire someone locally but no one was qualified. Recently, I told a friend working in Dallas, TX I was quitting our company because the environment at my site (different country) was not good. He offered to get me transferred to Dallas. I told him there were plenty of people in Dallas who could do my job; there was no way I could get a work visa. He told me there were ways around that.
