- servlet mapping problemsHey guys/gals. My first attempted at servlet mapping flubbed.
Background:
A friend at work suggested I store my source in webapps\wbrl\jsp
So I have Tomcat\webapps\wbrl\jsp\WebRoll.jsp
Currently I type http://localhost:8080/wbrl/jsp/WebRoll3.jsp
This brings up my application successfully.
I would like to be able to type http://localhost:8080/wbrl and have
it bring up my web page.
So I tried to change the web.xml, but it doesnt work.
<servlet>
<servlet-name>WebRoll3</servlet-name>
<servlet-class>WebRoll3</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>WebRoll3</servlet-name>
<url-pattern>/wbrl/*</url-pattern>
</servlet-mapping>
<url-pattern>/wbrl/*</url-pattern> causes "Wrapper cannot find servlet
class WebRoll3 or a class it"
How do i fix this? Do I use filter mapping? I got totally lost in the
filter mapping explanation.

void methods cannot return values, however, i noticed that i can still
use "return" without any value to exit a method like this:
public void myMethod(int arg0)

if (arg0 == 0) return;
...
}
question: is the above ok or will i get errors with other java versions.
i'm using jre1.4.1_02 in eclipse.

- Tomcat is giving the wrong MIME type?I use Tomcat serves a web application. I put all the files including
jsp, css and javascript file inside the Tomcat server.
When I request a jsp page through both Firefox1.5 and IE6, I found the
css and the javascript files are not loaded correctly.
I used LiveHttpHeaders to inspect the request and response headers. I
found that the server is giving text/html to the Content-Type of all
the files.
Is the problem in Tomcat configuration or in the browser?
Any idea?
TIA...

- Java coding with Agile PLM SDK - QuestionHello,
I was wondering if any one out here is dealing with a PALM System called
Agile and has some experience with the Agile SDK. If so can you email me, I
have a question on the SDK.
Also if any one know where I might find like a forum or message board that
deals with The Agile PALM system that would be help full too.
Thanks

- Graphics2D question.Hello,
I want to build my application from three main classes.
1. A frame class to handle file operations.
2. A Drawing panel to render images to.
3. An engine to perform the actual rendering.
All the examples I have read so far for Image stuff in Java have
everything stuffed into one monolithic class, and the crux of the
rendering seems to be done in paint(Graphics g) or
paintComponent(Graphics g) using a g2d object cast againg the parameter g.
If I wanted to do calculations for rotations translations etc I can do
this with the AffineTransform class setX methods, but the drawImage
method of g2d seems to be handled in the paint/paintComponent methods.
This is fine until I want to specify x, y arguments in the drawImage
Method as neither Paint or PaintComponent take these parameters in their
method signature how can I do this, is there another way to draw apart
from the paint/paint component methods?
Any help appreciated.

- Java process title editingI need a component that takes a String and puts it into Unix process
table by calling natively setproctitle. On Windows it can do nothing, I
don't care.
Also a possibility to use variables such as number_of_threads would be cool.
Why? When running a lot of Java server stuff on a Linux box it's really
hard to tell which process is which. Especially in production
environment "kill -9":ing makes me always feel quite uncomfortable...
If there is no such thing, then I'll have to roll my own. But better to
check first, don't wan't to reinvent stuff. :) Google didn't turn out
anything. ..

- tomcat authentication questionI'm fairly new to configuring server.xml and web.xml files in tomcat 4.
I am trying to require password authentication for access to a
subdirectory called "update" located within ROOT. I want all files
located directly in ROOT to be available without a password. I am having
trouble determing the correct path to use for the <url-pattern> in the
web.xml file in WEB-INF so that only the files in the subdirectory
"update" within ROOT are password protected.
If I use <url-pattern>/*</url-pattern> then no pages on the site may be
accessed without a password no matter their location. I am presuming
that this means I have set up the basic authentication correctly in
tomcat-users.xml, server.xml (in conf) and web.xml (in WEB-INF) but that
I now simply need to put the correct path into the <url-pattern> in
web.xml.
However, when I use <url-pattern>/update/*</url-pattern>, I can access
all of the pages within the update directory without being asked for a
password. I've experimented with many different paths and have not had
luck with any. I have been careful to close my browser and open a new
one each time between tests. I've also tried restarting tomcat for every
new test. Nothing works.
In my server.xml file, <Realm
className="org.apache.catalina.realm.MemoryRealm" /> is located within
the <Engine> tag (not within <Host> or <context>).
Have hunted around for a solution without much luck. I assume that I am
missing something very simple.
Here is my complete web.xml file...
<web-app>
<display-name>SMUpdate App webxml</display-name>
<!-- form login security tags -->
<security-constraint>
<web-resource-collection>
<web-resource-name>SMUpdate</web-resource-name>
<url-pattern>/*</url-pattern> <!-- this works but causes password
to be required for access to all pages on entire site -->
</web-resource-collection>
<auth-constraint>
<role-name>smupdate</role-name>
</auth-constraint>
</security-constraint>
<login-config>
<auth-method>BASIC</auth-method>
<realm-name>SMUpdate</realm-name>
</login-config>
<servlet-mapping>
<servlet-name>invoker</servlet-name>
<url-pattern>/servlet/*</url-pattern>
</servlet-mapping>
</web-app>
Any suggestions would be very much appreciated.
Thanks.

Okay, it breaks down like this. File handling is just that, things you
want to do to a file. You can read files and write to them. Whenever
you read to or write from a file, you have to handle exceptions, the
main one being FileNotFoundException (in case there's no file to be
found). That's why they want to empahasize both of those points.
Whenever you're doing I/O, you have to use try/catch blocks. I think
I/O exception's the other one you have to handle but my memory is
fuzzy on it right now.

- Middle Tier for Java and PHPHi,
Let's say you have a Java SE Application and a PHP Web App that are both
accessing a database directly. You want to control things more formally
by using a common middle tier (enforcing things in addition to database
constraints / sprocs).
Any experience on what works and/or recommendations?
Thanks,

Even so, both the main method and the main thread exit directly toward
the beginning of a typical GUI application. What may *not* end, on some
operating systems, is the native OS-level thread that is used to
implement Java's concept of the main thread.
It's undefined whether that OS-level thread lives or not following the
termination of Java's main thread. It must on many platforms in order
to get around POSIX and other similar thread conventions (including
Win32, IIRC) that designate it as a special thread. On a system that
implemented a very different threading convention, though, which didn't
carry POSIX and Win32's pre-multithreading baggage, it would probably
not be necessary.

It doesnt make sense to put this stuff into two different source
packages either. One source package is enough. We need to finish the
icedtea package. Then we will have all we need in Debian.
Cheers,
Michael

Things seems to have changed since I started packaging. Back then
it was clearly two diffent sources.
>From what I have read about icedtea it is just a build framework
for openjdk. Or is it already included?
In any case it would be most welcome with a free jvm with classes
inside Debian. :)
This means that I'll merge these two bugs into one. :)

More or less, yes. In Debian the built binaries will provide a JDK
replacement.

- Tweaking DefaultTreeCellRendererHello,
I'm implementing Drag & Drop for my JTree and I got everything working so far.
There is only one thing that I'd like to add: I would like to highlight the node
that is the current drop target somehow. I did manage to select the node
during my dragEnter() and dragOver() events, but I'd rather not change the
tree's selection during dragging.
So I thought I could customize the TreeCellRenderer used. What I did is the
following:
I extended DefaultTreeCellRenderer and added a method to set the current drop
target row. When creating my tree I set the new renderer as the tree renderer
(which is working because I can see the methods beeing called when adding a
System.out.println())
The I overwrote getTreeCellRendererComponent(). Before calling the
super.getTreeCellRendererComponent() I check if a drop target row is set, and if
it is I pretend the cell is focused:
public Component getTreeCellRendererComponent(JTree tree,
Object value,
boolean sel,
boolean expanded,
boolean leaf,
int row,
boolean hasFocus)
{
boolean drawFocus = hasFocus;
if (this.dropTargetRow != -1 && row == this.dropTargetRow)
{
drawFocus = true;
}
return super.getTreeCellRendererComponent(tree, value, sel, expanded, leaf,
row, drawFocus);
}
But this does not work. I have added debuggin code and the dropTargetRow
variable is set and initialized correctly.
What am I missing here? When I pass a hardcoded true or false to the super call,
it does work (all nodes either always focused or never)
Thanks for any input

if you need a datetimepicker-control for java,
you can find one on my side:
http://www.software47.de/eng/software/datetimepicker/datetimepicker_en.htm
it's absolutely free, you can use it as you like.
since i was looking for a free datetimepicker myself, but found nothing, I
wrote one the last days...
If you find bugs or have ideas to better it up, let me know.

- CLASSPATH clobbering, win2kfrom <http://java.sun.com/j2se/1.4/install-windows.html#Environment>:
"Choose Start, Settings, Control Panel, and double-click System. On
Microsoft Windows NT, select the Environment tab; on Microsoft Windows
2000 select the Advanced tab and then Environment Variables. Look for
"Path" in the User Variables and System Variables. If you're not sure
where to add the path, add it to the right end of the "Path" in the
User Variables."
under System Variables the value of "Path" is:
"C:\Program Files\Java\jdk1.5.0\bin\"
from
<http://java.sun.com/docs/books/tutorial/getStarted/cupojava/win32.html#2c>
I followed these instructions:
"If you still have problems, you might have to change your CLASSPATH
variable. To see if this is necessary, try "clobbering" the classpath
with the following command:
set CLASSPATH="
"clobbering" fixed the problem, "java HelloWorldApp" worked fine.
However, since I need to clobber the CLASSPATH variable I need to
change it's value, but to what, pls?

- Eclipse Tomcat Project StructureHi All,
I am using Eclipse 3.0 with a Tomcat plug in.
I am trying to create multiple web projects using Tomcats webapps
directory. Eclipse will let me set up one project with under the webapps
folder but when I try to add a new project I get the following error
C:/jakarta-tomcat-4.1.30/webapps and C:/jakarta-tomcat-4.1.30/webapps
overlap.
This I am sure will have a simple explanation... I am thinking that it
should be ok to work on multiple web projects with different names at the
same time under Tomcats webapps folder ?
Thanks in advance

The Eclipse IDE is very huge and bloated. You might
want to take a look at one of these alternatives:
http://jedit.org
Supports several development languages and a huge
assortment of feature plugins. You can script out
your own shell tools as macros and make them available
as buttons on your toolbar.
http://netbeans.org
Similar to JEdit but with a GUI designer for Java apps.
Also lots of plugins and multi-language support.
The nice thing about having IDEs written in Java is
the cross-platform support; using the same environment
on any Java-enabled OS.
