RE: I've officially decided that JSTL is one of the worst things to ever happen to mankind
Ivan, tell us how you really feel :-)
Not to be a smart As_ but Ive felt the same way about changes, for the
better? not always, but it progresses to the next point where there is
an improvement. For example, remember the old client/server
technology? It sounded good at first until everyone discovered that
maintaining Fat clients was a total nightmare. Now we use java and the
client is a browser, is it better? Yea, probably, but it could be
simpler if all browsers worked the same. Use the technology that fits
your needs.

Subject: I've officially decided that JSTL is one of the worst things to
ever happen to mankind
After getting convinced to try JSTL, I learned the following things:
1. JSTL and EL are inefficient. Tests on similar pages clearly
showed that. (compare - ${name} with %=name%, run in a loop 1
times, youll see the difference)
2. JSTL is cumbersome someone told me once that the reason they
use JSTL is because their designers are scared of %=% code, but they
have no problem throwing around XML statements. Well, whats my advice
to him: hire new designers, and fire your high school students. On one
hand, yeah ${parameter.name} is very nice relatively to
%=request.getParameter(name)%. But after playing around with JSTLs
ull see what I mean. Also, when your designers screwes up with the
logical structure of your web-site cuz he thought he could just throw
around tags, youll think twice. Which brings me to the next point
3. XML is for data flow, not for logic. Whoever the hell thought
of tags like c:if and c:choose should be murdered in the worst way
possible. With JSTLs exporting and importing variables, and all the
logical statements and loops, the whole idea of XML gets destroyed.
4. EL encourages sloppy syntax. It doesnt even have data types
(well it has on the bottom level, but not on the surface). Remember
JavaScript? Did you know that at first, it was supposed to be
server-side scripting language? You know the reason it didnt make it
(one of the major ones)? Because of its sloppy syntax and the amount of
errors it caused. Why bring it back?
5. Server-side content and client-side content should be
separated. When everything looks like HTML (in some way), its hard to
tell what actually gets processed, and what gets sent to the client as
static (if you have all-nighters, youll understand).
6. JSTL is time-consuming. The whole idea of JSTL was to speed up
the process. Not only is it less efficient than embedding code the
normal way, but it also takes you forever to make something new with it.
Dont believe me? Just try it.
7. The only reason JSTL was made is so that guys at Apache could
write some stupid book explaining its hella complicated syntax, and
charge people $50 for it. See, its just like the C++ story. Why was
C++ invented? To give programmers jobs. No other reason whatsoever, C
does whatever C++ does just as good, and better. So I am not sure if
JSTL is a step to having advanced developers who get paid more because
they took time to learn retarded JSTL syntax and EL, or is it just
Apaches developers way of making money (and I am surre Oreilly and
the bros are thankful too).
Point of this message: DO NOT USE JSTL OR EL. Youll regret it. I
did.

RE: how to check if a String is empty?
Every once in a while you see this question pop-up and the same thing
happens...you get a whole bunch of answers. Remember that a String is
an Object and not a primitive e.g. int, long etc. So in that regard if
it is not an int but an Integer what would you use to test for an empty
String. Think about it.

Depends I guess :) I personally find the use of a magic number to be

more clear.

Howdy,
if (test == null || test.trim().length() == 0 ) { } is simpler.

Wouldn't test.trim().length() be a better test? length() after trm
would
tell you if non white-space was left.

Hello,
maybe this is not the perfect group for my question, but as my
problem
appears at the development of JSPs and tomcat is concerned with
that,
I
hope you can answer it.
I often see the condition
String test = req.getParameter(test);
if (test == null) {
/* string is empty */
} else {
/* string contains something */
}
But if test contains just blanks and other whitespaces, it's not
null,
but doesn't contain usable data anyhow. How can I check if a
string
contains whitespaces only? I though of something like
if (test == null || test.trim().equals()) {
}
but there's no trim()-function, right? How do you solve this
problem?
With whitespaces I mean blanks, tabs and newlines.
Regards
Marten

Subject: RE: How can I access a file located in WEB-INF
Further, you will probably want to be able to construct the path to
/WEB-
INF
at runtime rather than hardcoding paths... You can do that as follows:
String fullPath = getServletContext().getRealPath(path);
where path is a context-relative path (can include a filename if you
want).
For instance, I use this in a Struts plug-in to initialize a custom
connection pool. The value I use for path is /WEB-
INF/ConnPoolConfig.xml.
The above gives you the full system path to the file (in my case,
C:\tomcat\webapps\toa\WEB-INF on my development machine), so you can
easily
open it then.
If you just use the above to get the path to a path (i.e., you want the
fully-qualified path to WEB-INF in the current webapp, but not a
specific
file), you will need to append a file separator character at the end
before
appending a filename.

RE: Can servlet generate a Web page first, then continue to run ?
Stan,
I have done something similar in a servlet by reposting to the
same servlet. The way I did this is by out-putting a hidden value in the
submission, then using a getParameter to retrieve this value on the next
submit. The first page was the user submitting some data, which when
submitted brought up a proof-read-page. If everything was OK they would
hit the submit button again (so the same page was actually generated
twice. The servlet would know to go to the correct processing part of
the servlet because of the hidden parameter would direct it to that part
of the servlet that did the processing.
For example, I hid a value called action with a value of
step2. In my servlet I had code that... if(action.equals(step2)){
..do something ...}+
So how might this apply to your problem? I'm not sure :-( but it
might spark an idea.

hi,
I want to show a page immediately after the visiters' Form Submitting
,then do some logical processing at backgroud(this will assume a long
time, so it may bother the visitor). I surpose to do these in one
servlet.
How can I do this?
Thanks

Problem closing connection w/pagination
I have a fairly simple tomcat 5.19 app, that queries a db, stores the results in a bean, and forwards the request to a result jsp. I use pagination with a pooled connection. I get my my datasource connection in the bean. If I try to close my connection after the first query and try to page back or forward I lose my connection. If I dont close the connection, everything works fine until I run out of pooled connections! ANY IDEAS? TIA Tom K. --- Outgoing mail is certified Virus Free.

RE: Relative directory addressing to parent directory
John, relative paths are always a headache (until you do some book-learning :-)). What I do is, right after my HTML tag I put in a line like this: HTML BASE href='%=request.getScheme()+://+request.getServerName()+:+request.g etServerPort()+request.getContextPath()+/ %' What the line above does is gives you the full path as your base reference. You can put 'kind-of' the same line in your regular html pages by using just the relative paths. Some may argue with the approach I use; if you include footers` and headers though and use the line right after your HTML tag your relative path will always be the same.

RE: problem with url - extra / appended before action
Hi Chris, Frames are very inconsistent on different browser, so most developers try to avoid them. With that said, some times you have to tune you path to work with the classpath. First of all see where your path is pointing to by use a few commands e.g. String path = request.getContextPath(); System.out.println(The path in SearchResultsPage is + path); String basePath = request.getScheme()+://+request.getServerName()+:+request.getServerP ort()+path+/; If you are using a jsp, simply enclose the above code in % % Now that you know your path info, the next thing to do is determine if you can make it all work together by tuning your path info. For example, when viewing your source code html out put, look at the path, sometime, you need to ad a ../myPath to go back a directory! Now other times (I dont know exactly what your working with, so excuse my ignorance) you may have to have a base path set up so all you relative path information can be base on that. For example you may need to ad code such as this: BASE HREF=%=request.getScheme()+://+request.getServerName()+:+request.ge tServerPort()+path+/ % which gives you a base path to work off of.

RE: Problem with Tomcat 5.0.19 and JSTL
The key to getting Tomcat 5 to work with JSP 2.0 and expression language is to copy the standard.jar and the jstl.jar (that already exists in Tomcat5s examples/lib directory) into the lib directory you are using for your app. You DO NOT have to edit the web.xml file at all but the web-app tag must be replaced with this: web-app xmlns=http://java.sun.com/xml/ns/j2ee; xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance; xsi:schemaLocation=http://java.sun.com/xml/ns/j2ee web-app_2_4.xsd version=2.4 Then in your jsp page you are going to use you will have these lines at the top of your page: %-- These two taglib DIRECTIVES define the two tag libraries used on this page--% %@ taglib prefix=c uri=http://java.sun.com/jstl/core_rt; % %@ taglib prefix=sql uri=http://java.sun.com/jstl/sql_rt; % Should work then!

RE: redirecting uploaded files in tomcat5
Kay,
What you need to do is copy or move the directories (on the same
machine) e.g.
/**
* Copies all files under srcDir to dstDir, if dstDir does not exist, it
* will be created.
*/
public void copyDirectory(File srcDir, File dstDir) throws
IOException {
if (srcDir.isDirectory()) {
if (!dstDir.exists()) {
dstDir.mkdir();
}
String[] children = srcDir.list();
for (int i=0; ichildren.length; i++) {
copyDirectory(new File(srcDir, children[i]),
new File(dstDir, children[i]));
}
} else {
copy(srcDir, dstDir);
}
}
// Copies src file to dst file.
// If the dst file does not exist, it is created
void copy(File src, File dst) throws IOException {
InputStream in = new FileInputStream(src);
OutputStream out = new FileOutputStream(dst);
// Transfer bytes from in to out
byte[] buf = new byte[1024];
int len;
while ((len = in.read(buf)) 0) {
out.write(buf, 0, len);
}
in.close();
out.close();
}
Now if you have to copy a file to another computer, take a look at using
an ftp client and redirecting it (using a 'put') to another computer.
You may even look at using a native method via jni for doing your file
transfer. Have a look here:

RE: Question on debuggin JNDI/prepared statement in a bean
Harry,
Yes the ClassifiedAd and UniqueDateId are two parameters taken
from an html form, the values of ClassifiedAd and UniqueDateId are used
in a prepared statement for substitution of ? and ? the results are then
forwarded to a results jsp, which used the getXXX() to retrieve the
values from the bean.
I have this code working in another form as a Servlet using JNDI
and prepared statements. In the servlet the JNDI connection is made in
the init(blah, blah) and calls the super.init(config) which I
super.init(config) is implicit from reading the Tomcat docs.
The bottom line on this, is how do you set up a JNDI connection
in a bean, use a prepared statement (in a bean), retrieve a resultset
and forward the result for the results jsp to retrieve the value from
the bean.
Finally, I apologize to those who feel this is off topic. I have similar
code working in Resin but for the life of me, I can't get it working
with Tomcat 5 :-( I searched all the archives and can't find a good
example for doing this.
TIA Tom K.

RE: Question on debuggin JNDI/prepared statement in a bean
Not exactly...it is not the same! I have it working with a connection pool, mySQL and JNDI. To keep my reply short it goes like this within the bean: getDBConnection(); // get the connection prepareStatement(); // prepare the statement rs = pstmt.executeQuery(); // execute the query and of course after that I get my parameters. In a servlet you have an init() statement that executes only once which you get your db connection in, also you need to call super.init(config), where you don't have to do this in a bean, because it is implicit. (By the way, if someone wants an example, I will post it, but you'll then be my wife.) Next challenge is I have a blob that I set and get, but when I get the blob on my results page, it comes up with something like this @1eb2473 which I assume is an address. Anyone know what know how to get, what's in the address. Maybe open a stream? TIA Tom K. -Original Message- From: Harry Mantheakis [mailto:[EMAIL PROTECTED] Sent: Friday, March 26, 2004 10:43 AM To: Tomcat Users List Subject: Re: Question on debuggin JNDI/prepared statement in a bean Hi Tom how do you set up a JNDI connection in a bean? Exactly the same way as you would anywhere else, so if you have some code working in a servlet, copy it. To be precise, it is a database connection, acquired from a DataSource, which is itself acquired via a JNDI lookup. The fact that your code is in a bean makes no difference. how do you... use a prepared statement (in a bean) Same as anywhere else. how do you... retrieve a resultset, and forward the result Again, same as anywhere else. BTW - you should not be passing about references to JDBC objects that are tethered (so to speak) to database connections - it is bad practice, and likely to cause connection (and memory) leaks. The best thing to do with database connections is, grab your data, store it in some collection object, and then make damn sure you close the db connection - usually within a 'finally' block which is guaranteed to execute, even when exceptions occur. Having stored the data you need in a collection object, you can pass that about as much as you like. That has not really answered your original question, but unless you provide us with all your relevant code we probably cannot solve the problem. Since you got it working before, I would be inclined to start again, making sure that you copy the same JNDI/connection procedures in your 'bean' as in the servlet that works. The fact that your 'bean' is not throwing any exceptions suggests, to me, that there is a bug (logic error) in your code. Starting over might sort that out. Sprinkle about a few (temporary) 'System.out.println' statements to see where your code gets to. Not cool, but they do the job sometimes! If you are using an IDE - like Eclipse - you can run in debug mode, so it's easy to see what is happening - though may be not with JSPs. Good luck.

Your question is a good argument for having the bean retrieve the
connection, do its processing, and release the connection. The results
you're forwarding can't be a java.sql.ResultSet, as that keeps the
connection open, but some other object containing the processed results.
Hand-in-hand with this approach goes the practice of getting a handle to
your connection pool in a ServletContextListener. The listener can make
a getConnectionPool() or getConnection() method available for use by
your beans. This approach has several advantages over the servlet init
(or jspInit for a JSP) design, all of which have been discussed in the
past on this list so if you're interested you can search the archives.

I'm running jakarta-tomcat-5.0.18 on OSX.
I've got a trivial little JSP file:
jsp:useBean id=doubler class=DoublerBean scope=page
jsp:setProperty name=doubler property=in value=wugga/
/jsp:useBean
html
body
It looks like quot;jsp:getProperty name=doubler
property=out/quot;
/body
/html
and my DoublerBean.java file is pretty simple too:
public class DoublerBean

private String phrase;
public DoublerBean ()
{
// empty
}
public void setIn (String phrase)
{
this.phrase = phrase;
}
public String getOut ()
{
return (phrase + , + phrase);
}
}
When I run ant, I get a build/WEB-INF/classes/DoublerBean.class file,
but my jsp application can't seem to find the DoublerBean class. When
I reload my app through the manager and run it, I get:

I know there has been a bazillion messages about this. I
searched the archives and couldn't find anything to solve my extremely
annoying issue. It has to be something really simple but I just can't
find it.
My System:
Solaris 9
Tomcat 5.0.19
MySQL 4.0.18
Connector J 3.0.11
I have the connector J jar in the /usr/local/tomcat/common/lib dir.
I have basically copied the HOW-TO located at.
