Re: tomcat install problems on Tru64unix

[Mr. Cristian Romanescu]

Hi,
I'm not sure if this would help, but maybe you should try setting 
CATALINA_HOME, since new releases of Tomcat.
also you might want to run "catalina.sh run".

Bye!

Hi, 

I installed J2SDK V1.4 and tomcat on Compaq Tru64UNIX v5.1 successful, set TOMCAT_HOME and JAVA_HOME variable to proper directory, but failed to startup with startup.sh,  there is no corresponding process running and also, no explicit error apears. Only in output log, it recorded:

# more catalina.out

usage: java org.apache.catalina.startup.Catalina [ -config {pathname} ] [ -debug
] [ -nonaming ] { start | stop }
usage: java org.apache.catalina.startup.Catalina [ -config {pathname} ] [ -debug

I do not know where the problem is, J2SDK? or tomcat?   

thanks you for your kindly help!

Re: deploying servlet ?

[Mr. Cristian Romanescu]

The first search of Goole after : "Deploying a servlet in Tomcat"...
http://www.nacse.org/~yoon/tomcat-howto.html

You do the rest...

Cheers.

Hi Y´all
If I make a servlet and compile it, where am I supposed to place the class file, and which files should I add the context to ? 

I was reading a tutorial on http://wireless.java.sun.com/midp/articles/tutorial2/ but that seems to be the another version of Tomcat, I´m running 4.1.12, since it talks about adding the context to conf/server.xml but I can´t find anything like that in conf/server.xml

Is there a homepage with a good instruction on how to add a first servlet to tomcat ?

Sincerely

Re: Tomcat autostart on Linux

[Mr. Cristian Romanescu]

It depends on how it's installed, also Linux distro

If you have RedHat and istalled via rpm distro, you should have in 
/etc/init.d/ a script named tomcat4 that launches Tomcat @ statup.

 4 -rwxr-xr-x1 root root 3055 Mar  4  2002 tomcat4

(I'm not also a linux expert, but I suppose that should be marked 
executable.

also you can stop/start manually invoking
/etc/init.d/tomcat4 

Here's a quick'n paste solution

Re: plz help, I cannot determine why this is not working????

[Mr. Cristian Romanescu]

In my oppinion it's your application fault and not Tomcat's. It would be 
helpful to send the code snippet from place where your code throws 
NullPointer...

But first you should try to put some System.outs. out there and see 
where the code hangs...as that exception doesn't give (me) a clue about 
what's happening..

Re: Shared Class Loader (4.0.5) and (4.1.12) Win 2K

[Mr. Cristian Romanescu]

1. the jar should be placed in 'webapps/yourwebapp/WEB-INF/lib'
2. the jar should not be corrupted (check if it's ok) - It happened a 
few times that jar was corrupted (mm.mysql-2.0.4-bin.jar) so when I 
looked inside archive nothing was there...
3. I don'y use mysql-connector, but plain "mm.mysql-2.0.4-bin.jar" so 
check also if packages are correct!

Good luck!

Re: JSP's, scriplets, and logic

[Mr. Cristian Romanescu]

Think of it, you get sloppy, another gets sloppy, so if all would get 
sloppy and just drop code wherever it came's first in mind, who will 
stay and maintain the code?

I write because, I stand now & bitchin' that someone else wrote whatever 
his mind shit out...

Keep in mind that you develop an web application and someone tomorrow 
tolds you that an Java thin client would also be useful, and in no more 
than 2-3 weeks...so I'll what you'll do!?
Let me see you cutting from JSP and paste it in Java sources, day & night...

Wouldn't be nice that you get your logic seperated so you would only 
call you classes to do the DB queries and then use them as Vectors 
lists, whatever you wish and display them, for example!?

Well, maybe isn't that bad, but you get the idea...

Regards,
Cristian...

Re: tomcat 4.1.12 not starting- exception

Actually if you want to use JDK 1.3.1 you need xerces XML parser, which 
lacks on LS distribution which is part of JDK 1.4.1 so no need to 
include it in Tomcat also...

Re: tomcat speed

[Mr. Cristian Romanescu]

seems very strange, because I never have to wait so much for Tomcat to 
start...

1. Of course you could read docs and fine-tune the server.xml to your 
needs, i.e. removing uneeded connectors, realms (correct ?) that you 
don't normally need for your app.

2.Get a better processor ;)

Cristian

Re: question about session behavior

[Mr. Cristian Romanescu]

Hi, David.
There is one detail, Tomcat uses so called (I think) persistent 
sessions. Meaning...
If you close Tomcat, it creates a file 
($CATALINA_HOME/work/Standalone/yourwebapp/SESSIONS.ser) where present 
sessions are serialized.
Also when you restart Tomcat, that file is deleted. So basically when 
you close Tomcat your sessions aren't really destroyed, but saved for 
latter restart.

Hope this help.

Regards,
Cristian.

When I shut down Tomcat, shouldn't HttpSessionListener.sessionDestroyed() be called for each existing session?

When users authenticate to my application, I store their username and encrypted password in a database where it's associated with their session. When the session is destroyed, I have a session listener delete the database row associated with that session. However, when I shut down Tomcat I end up with orphaned rows in the database.

Is there a way to have HttpSessionListener.sessionDestroyed() called for each session when shutting down Tomcat?

TIA!

Re: Problems with installation on win2k advanced server (Java exceptionsthrown)

[Mr. Cristian Romanescu]

Hi!

I remember we had the same problem on the web server where using Tomcat 
4.0.3 with JDK 1.3.1, so the resolution was to upgrade both Tomcat & JDK
since on the test server (Tomcat 4.1.12 + JDK 1.4.1_01 worked 
perfectly). From what I could see you are using latest version of 
Tomcat, maybe try upgrading JDK (I don't think will resolve, but it's an 
idea)

Did you tried to request other pages (not index.jsp) and see if they 
compile...?
Also you could try another version of Tomcat, I think...

Hope this helps...

Cristian.

Re: TOMCAT Crashing down

[Mr. Cristian Romanescu]

Hello, again.
:-\  IMHO you should try using diferent distribution of  JDK / Tomcat (I 
think Tomcat 4.x is better).
Also check if driver it's ok (i.e. works in other contexts / applications).
If  Tomcat is shutting down right after it starts, then there is a 
problem loading one of the webapps libraries (jars classes etc), try 
disabling and see what happens.

This is what I would do...

Re: !!!HELP!!! how to execute an external .exe-file (+Parameters)that creates data-files I want to use later in my servlet

[Mr. Cristian Romanescu]

here's a  sample of code that would send an e-mail using mail command 
under Linux.
I guess that the exe probably should be within your PATH
As you can observe, cmd[0] is the name of the app
cmd[1], cmd[2], .are command line arguments to the app

   private static void sendMail(String mailTo, String subject, String 
body) throws IOException {
   String []cmd = new String[3];
   cmd[0] = new String("mail");
   cmd[1] = new String("-s SUBJECT - " + subject);
   cmd[2] = new String(mailTo);
   Process mailProc = Runtime.getRuntime().exec(cmd);
   OutputStream outStream = mailProc.getOutputStream();
   outStream.write(body.getBytes());
   outStream.flush();
   outStream.close();
   }

hope this helps

error=2 means imho that the File is not found. How can I execute my

Re: could you help me please?

[Mr. Cristian Romanescu]

The problem isn't that easy.
First of all I developed an application using parallel port (it's a 
matter of choice :)):
I found a big issue accesing port from Java...finally my option was to 
write an dynamic library (dll) in Ms Visual C (because is directly in 
assembler)
where I wrote the basic I/O functions with parallel ports.
Then using JNI (Java Native Interface) I called the methods from java, 
wherever I wanted to send something to the parallel port.

Unfortunately this works fine only in '95/'98...in NT/2000 blah...you'll 
need privilege access (or you'll get privilege exception from kernel)
There is a way for this also...there is a program (i can't remember 
now... search google) which gives privileges access to ports to yer java 
virtual machine.
So I suppose you should start tomcat's JVM with this application 
launcher and then load the dll from there...

I wrote my app in Swing, so I can't help you further (ie where to put 
your dll or so...)


Hope this helps.

Yeah, like John said, you could also use Java Comm api, but 
unfortunately in my project, when I wanted to send something to parallel 
port, the print spooler started,
then complaining about corrupted print jobs, so it seems that port isn't 
directly accesed...in the final. Maybe for COM ports does work

Re: what is catalina?..

[Mr. Cristian Romanescu]

NO! You are completely wrong!

...Catalina is actually a beautiful princess with big blue 
eyes...and...blonde...hair...sitting there in your box all alone, forced to 
listen all the cr*p played by the TCP radio, more commonly on 8080MHz, 
(some high skilled actually succeed to accord it on the 80MHz, but that's 
though!)
Sysadmins, the bad guys or "company internal police" actually 
bring this Apache so she would not try to escape after all that stress.
And as in those love stories, the Apache and Catalina fall in love 
together, and after a little time come to life
those little kids also known as 'servlets'...living all together until the 
end of times (if they are on the Linux Planet, of course) or until your 
next electrical problem.

Go ahead and open yer box...and you'll see that i'm not kidding you...

Cheers...hope I raise yer morale...yet! :)))

This one I actually know :).  It is a popular fallacy that it is because
Jakarta is (as it happens) the capital of the island of Java in Indonesia.
The real reason is that it was simply the name of the conference room in Sun
where the project was launched.

Re: parameter order

[Mr. Cristian Romanescu]

Actually, from my experience you should not rely on the order of the 
parameters...There is no rule on that.

At 12:16 AM 2/21/2003 -0800, you wrote:

StringBuffer sb = new StringBuffer();
Enumeration en = req.getParameterNames();
for (; en.hasMoreElements() ;) {
String param = (String) en.nextElement();
String value = req.getParameter (param);
sb.append(param).append(":

}


The order of the parameters is not clear - it is
neither alphabetical nor as specified in the html
form.
Is it that IE is ordering the parameters in such way
when POSTing the data? Anybody knows about this? This
is just out of curiousity, not really needed anywhere.

Re: Autopostback in JSP

[Mr. Cristian Romanescu]

Here are some hints:

At 09:00 PM 2/25/2003 -0800, you wrote:
Hi,
1)  I want the contents of my HTML page display to
refresh automatically based on a selection made by the
user. I am using HTML + JSP.
For Example:
  There are three radio buttons
  - Thesis
  - Non-Thesis
  - Software Engineering
  Drop Down Menu1
If the user selects 'thesis' there should be one drop
down menu appearing on the screen else there should be
two drop down menus appearing.
 How can I do that?


You have to do on the radio buttons, an JavaScript function which handler 
onClick (I think) event.
It would be something like this:

Here is a sample how an drop-down list works (I have it handy...)

JavaScript function:

function MM_jumpMenu(targ,selObj,restore){ //v3.0
  eval(targ+".location='"+selObj.options[selObj.selectedIndex].value+"'");
  if (restore) selObj.selectedIndex=0;
}

Here is the Drop-list that implements this functionality.


  Please select a country
  Any country


As you can see I pass using HTTP GET method the param field which shows me 
what used has selected.

Now you could adapt this code to your needs.


2)  Also what function in JSP will allow my page to
display one image if the mouse is placed on it and
another image if the the mouse is not place on it?
2) That is called rollover and is done also from JavaScript. Search the web 
further for JS tutorials on that.
As a a startup, you should handle the onMouseOver and onMouseOut events in 
a  for example

here is some sample code:
