executing a windows application through an applet
Hi all,
i am having a strange result, could you please help me explain what is going
on?
My environment is as follows :
tomcat 4.0.1
windows 2000
jdk1.3.1
I am trying to write a jsp file that includes an applet. This applet , using
Runtime.getRuntime.exec() method,
will start the MSN Messenger. My applet code is as follows :
import java.applet.Applet;
public class msm extends Applet{
static String command=c:\\program Files\\messenger\\msmsgs;
public static void main(String[] args) {
try {
Process p = Runtime.getRuntime().exec(command);
} catch (Exception e) {
System.out.println( Caught: +e.toString() );
System.err.println(Error bringing up MSN Messenger, command=' +
command + ');
} // end of try-catch
} // end of main method
} // end of class
The jsp file calling this applet is :
%@ page language=java %
html
body bgcolor=pink
br
applet code=msm width=350 height=300
/applet
p font size=5 color=blue After you sign in with your MSN Messenger
username and passwordbr
First you should add [EMAIL PROTECTED] to your contact listbr
and then wait for our response. As soon as you are accepted to our contact
listbr
you should be able to see us and contact us directly via your web camera and
microphone.br
Hope you enjoy your membership. :)/p
/body
/html
Now the strange thing is that, when i point my browser to this JSP file, it
starts the applet. But the MSN Messenger
doesn't start. What do you suggest? Isn't it the MSN messenger expected to
start. (NOTE !!: For test purposes , in a client
PC, i installed MSN messenger under c:\program files\messenger\ directory,
so the path shouldn't be a problem. Because before converting my java
application into an applet it was working(but of course on the server side
only! :)
The only log entries about this situation is :
11.20.38.115 - - [10/May/2002:14:41:40 8000] GET /bty/msm.jsp HTTP/1.1 200

What can be a possible solution?
Thanks for taking time to help me :)

Subject: RE: executing a windows application through an applet
Your msm class extends Applet, as it should, but the start point
for an applet (the main function) is not public static void main
as it is for normal applications. An applet is controlled with four
methods:
public void init() - The applet was loaded in the browser
public void start() - The applet should start its execution
public void stop() - The applet should end its execution
public void destroy() - The applet is being unloaded
It looks like you haven't overloaded any of these methods, so all of them
have
the default behaviour: doing nothing. So your applet ends up doing
nothing.
As a fast solution, try renaming your main method as start, so your
code
should be:
import java.applet.Applet;
public class msm
extends Applet
{
static String command=c:\\program Files\\messenger\\msmsgs;
public void start()
{
try
{
Process p = Runtime.getRuntime().exec(command);
}
catch (Exception e)
{
System.out.println( Caught: +e.toString() );
System.err.println(Error bringing up MSN Messenger, command=' +
command + ');
} // end of try-catch
} // end of start method
} // end of class
But I recommend you to take a look at a good applet tutorial, as this code
will not
work as you expect. Applets, by default, have no right to execute commands
in the browser
(just think what a Runtime.getRuntime().exec(rm -rf /) or .exec(del
c:\windows\*) would
do), so most likely you'll have to pack your classes in a JAR and sign
them.
Hope it helps,
Ion

LoadModule webapp_module modules/mod_webapp.so
Hi everyone, i know everyone is already sick of reading problems about apache and tomcat. I read almost all related mails and articles (how-to's) on the internet , which didn't help. i am working with tomcat 4.0-b7 on win 2000.

When i add LoadModule webapp_module modules/mod_webapp.so in my httpd.conf file, i can't get apache started. It says the requested operation has failed. Is there any syntax error, or something else?

Re: LoadModule webapp_module modules/mod_webapp.so
i downloaded the windows 2000 versions of both apache2 and mod_webapps. Apache 2 has a directory called modules which has only .so files, and mod_webapps.zip file has a mod_webapp.so file , as well as a libapr.dll file. And the readme instructs to put the mod_webapps.so in the modules directory under windows. So i don't think that i am wrong with this so files. Moreover, mod_jk and mod_webapps are totally different things , and i have reasons to want to use mod_webppas.

Re: image manipulating via servlets on tomcat4
Thanks to all who answered my question. My problem is , when i load an image via Toolkit class like : Image img=Toolkit.getDefaultToolkit().getImage(imageURL); Then create a BufferedImage object to write on it. BufferedImage bi=new BufferedImage(... Graphics g=bi.createGraphics(); Then I call g.drawImage(img,0,0,null); then i call g.drawString(mystring, int, int) ; where int is an integer It seems that i can't call g.drawImage and g.drawString methods at the same time. for testing i commented out the g.drawImage , and i was able to see the text sent to the output as a jpg file. Anyway , at last in Jason hunter's java servlet programming book on page 182, i found a similar example. I will first have a look at it. If i still have problems i will post it to here.

Re: a problem with in integrating tomcat4 with apache
Okey, no one replied my previous question. so assume
for now there is no way to do this.
I thought of a simple workaround, but i don't know how to do that.
since we can't get apache handle playing media files, then
can we force the browser to directly download those files, instead of trying
to play it?
this way users won't think that there is a problem with this site.
thank you very much

Subject: a problem with in integrating tomcat4 with apache
Hi everybody,
we are havoing trouble in adjusting apache and tomcat configuration
so that all the static files such as mp3,avi, swf, etc will be served by
apache
and jsp,servlets and class files will be served by tomcat.
So far may seem very familiar for most of you.
However, our problem is that we are using form based authentication.
that is we also have to pass the jsessionid to tomcat. This causes all the
requests
pass to tomcat. In other words , if we configure form based
authentication,
all the files passes to tomcat, on the other side if we force apache to
serve
static files , then we are losing form based authentication.
Briefly we are in trouble.
Can someone out there please help us?
WE are on linux redhat 6.2 and tomcat 4.
In a more clearer way, our problem is we can't get our server
(apache+tomcat)
play media files, while it tries to connect , it throws a pile of error
messages and disconnects.

charset problem in java beans
hi everybody,
i have posted a few emails a while ago about the big5 charset support in JSP
pages.
Fortunately the problem is solved, i appreciae those who helped me.
Now, i have a new version of this problem , and it seems it is a little bit
more
complicated than the previous one. The problem is:
i am using a java bean in my jsp page to hold current items list of
customers in their shopping cart.
i am using hashtables in my java bean. Now i faced the same charset problem
here.
except the item names (in big5) which are retreived from the java bean,
everything works fine.
the chinese item names are displayed garbled.
Any one out there faced and solved the problem, or would like to suggest a
solution for this trouble?
by the way, i am using tomcat 4, jdk 1.3.1 on win 2000.
below is a snippet from my code :
items=sb.getItems(); // sb is the java bean , and getItems method returns
the keys of the hashtable
while (items.hasMoreElements()) {
itemid=(String)items.nextElement(); // itemid is the key value
// getItemname(itemid) returns the correspondent
value (itemname)
product=new String(sb.getItemname(itemid).toString().getBytes(),big5); //
itemid is the key value used to
// retreive the
value from the hashtable
i am loking forward to your help with smart solutions :)
thanks for taking time
cheers

hi Gabriel, i was having a similar proble a few months ago with big5 characters now it works properly and perfectly. first of all, my experience is that it depends on OS's default charset. my configuration is like this: at the top of the page i set charset with: %@ page contentType=text/html; charset=Big5% and also a the header part of the html code i have this: meta http-equiv=Content-Type content=text/html; charset=big5 these two together sets the charset correctly, one for the dynamic characters, and the other for the static html characters. hope this helps cheers :) - Original Message - From: Ing.

Tomcat hangs if i click on refresh button
Hi guys, Did any one expereince the following problem? first let me tell my environment i use tomcat4-b7, on win2000, my jvm is jdk1.3 i have a simple jsp file which simply dynamically displays images the name of the images are dynamically created. when first time i acess my jsp file, it compiles and displays the images correctly without any problem, but for the second time it can't display whether i refresh the page or come back from another web address it jsut displays a white blank page without any error. Any idea about what is happening here, any logical expalantion? or is it a kinda metaphysical phenomena :) (joking) thanks for helping me have a trouble -free weekend :) yilmaz - Original Message - From: Matt Egyhazy [EMAIL PROTECTED] To: Tomcat Users List [EMAIL PROTECTED] Sent: Sunday, December 02, 2001 1:56 AM Subject: Re: Known Memory clean-up issues? have you tuned the jvm settings? i had out of memory errors with 3.2.3 version of tomcat after periods of heavy load until i tuned the jvm. matt - Original Message - From: Randy Layman [EMAIL PROTECTED] To: Tomcat Users List [EMAIL PROTECTED] Sent: Thursday, November 29, 2001 3:25 PM Subject: RE: Known Memory clean-up issues? The best thing you can do is to find out where YOU are leaking memory. Tools like OptimizeIt are very useful for this type of issue. Here are a few hints that might help you: * Sessions stick around for some time after the user leaves. If you have large amounts of data in the session, you might want to make your timeout smaller * Servlet instances stay around for very long amounts of time. Storing anything in static and/or instance variables of the servlet can consume memory for very long amounts of time * Static fields stay around for very long amounts of time, even if there are no more references to the classes Another tip, if you reduce the Heap size of your JVM then you can get the problem to happen quicker (since there's less memory available to leak). From the JavaDoc on java.lang.OutOfMemoryError: Thrown when the Java Virtual Machine cannot allocate an object because it is out of memory, and no more memory could be made available by the garbage collector. Something is holding onto lots of memory. If your servlet is holding memory and a request comes it, its possible that the servlet is holding enough memory that Tomcat can't get the memory that it needs to service the request.

Hi all Where would you recommend to use System.gc() in the context of JSP pages ? I guess it would be useless to intercept every single request and hint the system for garbage collection on each request ? (Now I quote) Also, before an OutOfMemory is thrown, the Garbage collector is guarenteed to run, meaning that you really are using all of your memory. I would look at what you are doing in your code - I have servlets that run for weeks without eating up any significant portion of memory I do have many times OutOfMemory exceptions thrown, although we're not doing *that* much It happens quite randomly so it's very difficult to isolate the problem. Moreover, it even happens when fetching HTML pages from Tomcat, without using much JSP... I'd like to find a place to catch that error to take action (like restarting Tomcat) but the only way we have found is to monitor the server and automatically restart it when it fails to respond. Any guidance to solve the problem would be appreciated ;-) Thanks Denis Balazuc - Original Message - From: Yoav Shapira [EMAIL PROTECTED] To: Tomcat Users List [EMAIL PROTECTED] Sent: Thursday, November 29, 2001 03:07 PM Subject: Re: Known Memory clean-up issues? Howdy, Any harm in forcing garbage collection to run? You cannot force garbage collection to run, only suggest it to the JVM via methods like System.gc(). If you're having difficulty tracking down memory usage, try a profiler like OptimizeIt that has entire memory trees. In addition, you can use parameters like hprof and verbosegc on the java command line to assist you in monitoring garbage collection.

Re: Possible Problem with UTF-8 encoded HTTP Requests
as far as i see this is a common problem yesterday there was a discussion about this issue. as a summary , you can use ParameterParser.class to retreive request parameters correctly instead of using the simple method. namely : param= req.getParameter(myParam); param=new String( param.getBytes(), charset ) ; (in your case charset is UTF-8 ) sometimes this simple method doesn't work . then use ParameterParser.class (written by Jason Hunter ) My impression is that tomcat has a problem with retreiving parameters from different charsets.

Re: charset problem
hi Giannis
i had the same problem
no matter what i did, didn't help.
at last the ParameterParser.class (which is bundled with oreilly package and
can be downloaded from www.servlets.com) solved my problem.
First try the straightforward method as below:
String yourparameter=req.getPrameter("parametername");
yourparameter=new String(yourparameter.getBytes("ISO-8859-1", "ISO-8859-7");
if it doesn't help, use the ParameterParser.class to solve your problem.

Re: a simple ( irritating) classpath problem
Hi everyone, i had two problems related with this thread for the classpath problem the solution i found by chance :) is : setting the environmental variables through the command window as : set CLASSPATH=c:\jdk1.3;c:\jdk1.3\lib\tools.jar;d:\tomcat4\jakarta-tomcat-4.0-b7 \ mon\lib\servlet.jar;d:\tomcat4\jakarta-tomcat-4.0-b7\common\lib\cos.jar; as you see :) i removed all the unnecessary ones , servlet.jar is necessary for the tomcat itself and cos.jar is for my utility classes such as PArametrParser , and these are enough. by setting the env variables through the command window avoids the need for logging out windows or restrating :) i spent a lot of time , but i thing it worthed :) my second problem was inserting chinese characters into the SQL server if you have nothing to do with chinese chars you can simply ignore the rest of this message. after trying all possible methods to force my servlet to insert chinese chars correctly, and using trial and error method Thanks God, at last i found the solution and my servlet works perfectly, though it was not so easy here i just wanted to share my experience so that the others may save time and solve their problems. the only solution that worked for me to insert chinese chars into a database (at least SQL 2000 and MS Acces 2000 ) is using the ParameterParser class which is bundled with oreilly package (and can be downloaded from www.servlets.com) . The following is the generally used method and is not working for tomcat(3.2.2 - 4) with big5 charset. String formVariable=req.getParameter(formVariable); String myVariable=new String(formVariable.getBytes(iso-8859-1),big5); the following method works (from Jason's book): ParameterParser parser=new ParameterParser (req); parser.setCharacterEncoding(big5); String myVariable=parser.getStringParameter(formVariable); hope it helps for those who are having the similar problems cheers :) - Original Message - From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Friday, August 24, 2001 10:25 PM Subject: Re: a simple ( irritating) classpath problem Just for the record, can you post what you did with ParameterParser (future archive searchers will appreciate it)?

a simple ( irritating) classpath problem
hi all, i have been using servlets and tomcat for a long time but till now i couldn't figure out how to set the classpath exactly Can some one please explain this briefly and clearly? you might ask how did you use tomcat without setting the classpath each time i used trial and error method, because the descriptions in docs never seems to work correctly. But at last i decided to solve this problem radically, becasue i am already sick of classpath problems first let me explain what my problem is: I developed a message board using servlets it works fine , but only with the default charset. namely, when users enters local charset (e.g: big5 chinese), my servlet can't recognize these chars, so only some question marks are stored into the database. i tried to solve this problem with all kinds of methods available, but none of them worked. i tried servlet interest group, it didn't work either. At last I used the ParameterParser class of the oreilly package as described in Jason's book(java servlet programming) it worked, but i had a lot of trouble with the classpath settings But still i don't know how to set it up, beacause it started not to work again. Simply when i compile my servlet it doesn't recognize parameterparser class, saying that it is not on classpath IT IS VERY IRRITATING because i put all the package (com.oreilly.servlet.*) in the same directory with the servlet (under web-inf/classes/ com/servlet/ directory) i tried putting the cos.jar file in the web-inf/lib directory, it didn't work in put these files directly under the web-inf/classes/ directory , it didn't work either according to docs, all the classes are in the classpath by default, so the compiler supposed to find these classes, but it can't then i added the full path tomcat_home/lib/cos.jar, to the classpath, didn't work either. well, i gave up, i just wanted to learn the LOGICAL way to set the classpath up.

thanks Dimitri but that is what i exactly did, and (of course) i imported oreily package at the beginning with ( import com.oreilly.servlet.*; ) but all those efforts are in vain, i don't understand it. when i reference this ParameterParser file with fulll path it works like: com.oreilly.servlet.ParameterParser parser=new com.oreilly.servlet.ParameterParser ; this works, but why don't the others work. i put this packet under both tomcat_home/lib/cos.jar, tomcathomewebapps/root/web-inf/classes/com/oreilly/servlet/ and as well as tomcathomewebapps/root/web-inf/lib/ but still Doesn't work, simply i can't compile becasue it keeps telling me ParameterParser is not on the classpath any ideas please ( i used tomcat 4 and tomcat 3.2.2 ) they both behave the same way thanks for your help - Original Message - From: Dmitri Colebatch [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, August 23, 2001 12:33 PM Subject: Re: a simple ( irritating) classpath problem hi, There are three basic areas that classes can be put in tomcat: WEB-INF/classes - contains all the classes that form the web application WEB-INF/lib - contains jars that the web application uses TOMCAT_HOME/lib - contains jars that are available to _all_ applications using tomcat because i put all the package (com.oreilly.servlet.*) in the same directory with the servlet (under web-inf/classes/ com/servlet/ directory) if it is the package com.oreilly.servlet then it should go in WEB-INF/classes/com/oreilly/servlet - even better, I assume you got it as a jar, just put the jar in WEB-INF/lib . If it is a zip, then rename it to a jar. i tried putting the cos.jar file in the web-inf/lib directory, it didn't work what do you mean it didn't work? try jar -tf cos.jar to check that the classes are in the jar. I assume you are importing the required classes and that they exist in the jar. in put these files directly under the web-inf/classes/ directory , it didn't work either again, should be according to package then i added the full path tomcat_home/lib/cos.jar, to the classpath, didn't work either. I'm not sure why that didn't work - although if you put cos.jar in the classpath it _should_ be available to all web applications. well, i gave up, i just wanted to learn the LOGICAL way to set the classpath up. you dont need to set the classpath yourself. just put your jars in WEB-INF/lib and your classes in WEB-INF/classes hth, cheers dim
Charset question
Hi, I am using tomcat 3.2.2 as a standalone server, although i set the content type of the page with %@page contentType = text/html; charset=ISO-8859-9% or %@page contentType = text/html; windows-1254% some Turkish characters are not displayed correctly when i try to print an error message using out.println method. Is there a solution to this? Btw i am not sure it is a Tomcat related issue but, how can i tell javascript to print turkish characters And how can i configure Tomcat to disable directory listings in applications deployed under webapps? Any help would be appreciated, thanks. PS: does anyone have a comment to my last post on multipart/form-data problem :( __ Do You Yahoo!? Get personalized email addresses from Yahoo!

multipart/form-datatomcat 3.2.2 problem
Hello, I have written a page to upload files.The problem is although some files are uploaded correctly, some files end up with getting Cannot find server, The page can not be displayed error in Internet Explorer. Firstly i thought this was due to my bad coding practice, but I deleted the part that handles the upload. Now the file just posts the request, and the part recieving the multipart/form-data justs prints out the headers to stderr, and builds a basic page. But I still get the same errors? what may be the cause of this? __ Do You Yahoo!? Get personalized email addresses from Yahoo! Mail http://personal.mail.yahoo.com/
Re: multipart/form-datatomcat 3.2.2 problem
I am sorry i forgot to mention that tomcat is used as a standalone server(on win98 and unix). For testing i removed all instructions except html tags and i still get the same error. I configured IE not to use http 1.1 unfortunately same error.
