Re: a simple ( irritating) classpath problem
Just for the record, can you post what you did with ParameterParser (future
archive searchers will appreciate it)?
Thanks,
Noel
HI ALL,
first of all thanks for everybody for your help
those garbled chars you see on your email are chinese characters(big5)
but i already translated it for those who may not be able to see
(understand)them
it says ParameterParser is not on the right classpath
Any way guys , finally after a lot of trial and error methods i managed to
make my
Tomcat to recognize ParameterParser
However, i am stil confused and didn't understand the logic behind the
classpath setting
because it seems to me that previously i had already done the same
settings,
but it ididn't work
now it works.
So i think the best idea is (as Craig said) One suggestion is to set up
your development environment to use Ant 1.3,
and let it take care of class path problems for you
i will try this method, otherwise handling classpath problems is really
wasting time
it takes longer time to set the classpath than developing the real
application
THANKS AGAIN TO EVRYBODY
CHEERS =)

What are all those weird characters? Not sure if they are doing anything

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)?

They are two different needs, and often require two different values. One suggestion is to set up your development environment to use Ant 1.3, and let it take care of class path problems for you. Instructions on how to do this are in the Tomcat 4 version of the Tomcat Application Developer's Guide, which can be found online at: http://jakarta.apache.org/tomcat/tomcat-4.0-doc-exp/appdev/index.html Nowdays, I routinely build and run webapps (and even Tomcat 4 itself) with *nothing* in my CLASSPATH variable. Whenever I need a classpath build, I just tell Ant to do it for me. Whenever I want a library JAR available in Tomcat, I just drop it into the top-level lib directory. Life is a lot less frustrating if you let tools do some of the work for you. Craig McClanahan

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
Re: a simple ( irritating) classpath problem
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 .
