Setting Classpath on windows platform

Hello
I was trying to set classpath of "D:\documentum\config" in my environment variable , i was doing it through command
prompt , the command i was implementing was
set classpath=D:\documentum\config;
but the when i was closing command prompt , the environment variable in windows named as ClassPath was not updating
i have also tried this command
set classpath=%classpath%;D:\documentum\config;
this also having the same result , so how can i set this property through command prompt
Regards

You can permanently set command line environmental variables through the advanced settings in Windows. You have to hunt around for it a bit, it is somewhere behind opening the right click properties of "my computer" (or whatever it is called in your flavor of Windows) and then choosing advanced. An "environmental variables" tab should be present there.
BUT! I would not advise you to set a classpath variable unless you fully realize that is only to make your development life a bit easier when working on the command prompt. When making your application ready for deployment the classpath must be managed without the variable. A script could work, or packaging everything up as an executable jar. When you start to work with an IDE like Eclipse or Netbeans you don't need that variable at all any more.

Set Classpath at runtime

Hi everybody! I'm using NetBeans IDE 3.6 and I want to change the classpath at runtime. I�ve tried to make:
set classpath="C:\Documents and Settings\Koening\Mis documentos\Proyectos";but it doesn�t recognize that sentence. If anybody knows how to change it at runtime please answer me.
Thanks for the replies!!!

I assume you were talking about a .bat file as you're writing that more or less in .bat format. The main problem if that's the case, is that you're not supposed to put quotes around the value:
set classpath=C:\Documents and Settings\Koening\Mis documentos\Proyectos
Actually changing the classpath at "runtime" (i.e., after the JVM is started) is more involved, and normally requires writing a launcher class which does nothing but create a URLClassLoader with the appropriate URLs, fetch the real main class from the new classloader, and executes its main method.

Trouble Setting Classpath on Windows XP

I'm having trouble setting up a classpath on Windows XP for SDK1.3.1_04.
I've tried Control Panel\Advanced\Environment Variables\System Variables. There was a Path variable present, to which I've added:
c:\jdk1.3.1_04\bin;
There wasn't a Classpath variable present though. I've tried adding it myself in System Variables as follows:
Variable name: Classpath
Variable value: set classpath=.;
But no joy. When I run "set" from the command prompt, there's no classpath present.
I'd appreciate any help.
Cheers.

Hi,
I am running on XP (unfortunately), but also win2000 and win98.
Setting up the classpath is not a problem, although if you are logged in as root, then it does not always show correctly.
Try logging back in as yourself and then checking the classpah through the set command.
Altrnatively, if this is not the problem, actualy try a reboot. which should not be necessary.

How to set classpath from java class ??

I have tried to use System.setProperty("java.class.path", "my class path string ") to set classpath dynamically. But it is not working. How to set it dynamically from java class ?? Thanks , gary

Look into the java.net.URLClassLoader. You can't set the classpath after the fact but you can specify URL's that will checked when you try to load a class with that loader.

Problems in setting classpath in vista

i am using Xp pro and Vista.
My issue is that I am not able to set classpath in vista.
i want to set classpath so that I can compile and run programs from different folder other than default one in which java is installed.
Please help.

My issue is that I am not able to set classpath in

Don't worry about it. The CLASSPATH variable is best avoided anyway. Specify classpaths for particular apps on the command-line. Teh Docs show you how

Please help.This suggests you're talking about PATH rather than classpath. Do you understand the difference?

Setting Classpath in linux

Hi !! Can anyone help me in setting classpath in linux to run servlets/? I tried using this command..but didnt work
export CLASSPATH="$CLASSPATH:/usr/share/tomcat5/server/lib/servlets-common.jar"
Thanks
Nive

in ur autoexec.bat file write the following
set PATH=C:\jdk1.5.0_04\bin;%PATH%
set JAVA_HOME=C:\jdk1.5.0_04
set
CLASSPATH=.;C:\jakarta-tomcat-5.5.9\common\lib\servlet
-api.jar;C:\jakarta-tomcat-5.5.9\common\lib\jsp-api.ja
r;C:\Servlets+JSP;..;..\..;C:\jakarta-struts-1.2.4\lib
\struts.jarThis response is meaningless. Principally because the OP specifically mentioned the use of LINUX. Not Windows.
I've taken the advice of other forum users by avoiding a system level classpath variable. I define the classpath each time I compile and run. Working on Linux I tend to use command line argument files ( http://java.sun.com/j2se/1.5.0/docs/tooldocs/solaris/javac.html#commandlineargfile ) which eliminates the need to redefine the classpath each time I compile or run my classes and apps. But others may do things differently.
Here is a website you might want to check out which pertains to setting the classpath on Solaris and Linux.

Help with setting classpath

Hi All,
I am new to servlets and JSP. I have a question regarding setting Classpath. My development directory structure is like this c:\..\desktop\java\project1\src\com\eg\web\e1.java. Servlet.jar file is in C:\Program Files\Apache Group\Tomcat 4.1\common\lib. I tried setting Classpath in windows 2000 using control panel=>System utility by this command
SET CLASSPATH=.;c:\Program Files\Apache Group\Tomcat 4.1\common\lib\servlet.jar . I try to compile my program by going into the whole development directory structure C:\..\src\com\eg\web using javac e1.java. But I get the error "package javax.servlet does not exist". Can somebody help me resolve this?
Thank You in advance
Jaya

Question 1: Are you using an IDE?
[IDEs ignore the system classpath]
Question 2: Did you try setting the classpath using the -cp option for javac, if you are not using an IDE?
[you could also try to print the classpath on command line to check if it has taken effect]

Setting classpath from the command prompt

each time i try to set the classpath from the command
prompt it is not always well done . can someone give
a good format

Anyway, try:
set classpath = ".;c:\document and settings\luke"

In UNIX how to set classpath

I know nothing about UNIX. pls kindly give me some instruction on how to set classpath in UNIX, thanks!

best way is to set in your .profile (name differs between different shells, but whatever the OS/Shell is, it should starts with . and has a 'profile' string in the name). Try ls -a to find the file, edit it, insert lines like this:
CLASSPATH=xxxx
export CLASSPATH
Use : to seperate different path/files.
then every time when you log in, the classpath is setted.
if you already logged in, use the above lines in command line, but it only set class path of the current shell/console.
anyway, you should learn Unix before you do anything, or you'll have more trouble. do a search in yahoo or google to find on line tuturials, and SUN's Java tuturial has some basic instructions on how to use Java in Unix.

Set classpath in Window 95, 98, ME

Hi,
Would anybody please show me how to set the class path in windows 95, 98, ME.
I used: set classpath=c:\ but it did not work
Thanks

hi,
Instead of using 'classpath' try and use just 'path'.
If JDK is installed in C: then the path would be
"path=c:\jdk1.3\bin;%path%"

Problems setting classpath...

hello guys...i am having a problem with what should be a very simple operation...
the classes i define are stored in the classes directory..inside, each package has its own subdirectory...
classes
beans
User.class
Cart.class
i have tried to change my classpath to reflect this location and instruct the compiler as to where to find those classes..
i have used the set Classpath command...
SET CLASSPATH=.;C:\Tomcat\common\lib\servlet-api.jar;C:\Tomcat\common\lib\mysql-connector-java-3.1.13-bin.jar;
C:\Tomcat\webapps\theagent\WEB-INF\classes beans.User;
but when i try to import beans.User in another class..it doesnt compile and tells me that the package doesnt exist...
please help....what else do i need to check to make sure the configuration is as it should be...
p.c User.java started with package beans;
thanks

That is correct because your beans.User class doesn't contain a
public static void main(String[] args) method, iow you can't run it by itself.i dont want to run the class by itself... i just want to import beans.User;
but it says that no such package exists...Then you have to be a bit more clear. You mentioned this command line:java -classpath C:\Tomcat\common\lib\servlet-api.jar;
C:\Tomcat\common\lib\mysql-connector-java-3.1.13-bin.jar;
C:\Tomcat\webapps\theagent\WEB-INF\classes beans.User;This sets the classpath pointing to two jars and a 'classes' directory.
You're trying to run the 'beans.User' class which I presume is stored
in a subdirectory of that 'classes' directory.
The java command works like this:java -classpath <jars and dirs here> package.YourClass... so you were trying to run your beans.User class all by itself. It doesn't
contain a main method hence the runtime diagnostic. btw, I don't know
why you appeded that whole thing with a semicolon.
kind regards,
Jos

Setting classpath in bat file

Hi,
I'm trying to call my java app from a bat file, normally I put all references to jar files hard coded in the bat file, but now I would like to loop over a lib directory and add all jars in that directory to the classpath:
I tried the FOR loop of Windows batch like this:
FOR /R .\lib %%G IN (*.jar) DO set CLASSPATH=%CLASSPATH%;%%G
but the classpath only contains the last jar file of the directory, what is wrong with that line? A for loop on unix is no problem.
THX

Hi,
I had teh same need, but neither
FOR /R .\lib %%G IN (*.jar) DO set CLASSPATH=!CLASSPATH!;%%G
works for me nor
FOR /R .\lib %%G IN (*.jar) DO set CLASSPATH=%CLASSPATH%;%%G
I have set the "ENABLEDELAYEDEXPANSION" also
