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.

what you have to do is.. you mysql database server should be running
next you have to download one of the version of mysql driver.. i downloaded mysql-connector-java-5.0.5
go to my computer right click - >advance tab -> click on environment variable -> put you path e.g. C:\Program Files\Java\jarFiles\mysql-connector-java-5.0.5\mysql-connector-java-5.0.5-bin.jar
into your classpath in a user variable section..
Try this code
import java.sql.*;
public class MySqlConnect{
public static void main(String [] args){
try{
Class.forName("com.mysql.jdbc.Driver");
String url ="jdbc:mysql://localhost:3306/test";
Connection con =DriverManager.getConnection(url,"root", "password");
System.out.println("Connection: " + con);
}catch(ClassNotFoundException cnfe){

How to set classpath in WinXP Home edition
Hello everyone,
Recently I have try to run the HelloWorld java code, but it come up with a error. (Exception in thread �main� java.lang.NoClassDefFoundError: HelloWorld)
Java programming Code:
public class HelloWorld {
public static void main (String args[]) {
System.out.println("Hello World!");
I also try to compile another simple program, and it come up with the simpler error, (Exception in thread �main� java.lang.NoClassDefFoundError: Add16And23)
Java programming Code:
public class Add16And23
public static void main (String[] args)
int sum;
sum=16+23;
System.out.println("The sum of 16 and 23 is " + sum);
HOW CAN I FIX THIS, I read other threads before, it say some about class path.
Do anyone know how to set it, in winXP?
Do anyone know the whole path that I should put in, in winXP?
What should I type in the (User variables for windows) and (System variables).
I have :
* (j2eesdk-1_4-dr-windows-eval) downloaded and installed;
*WinXP Home edition Version 2002 Service Pack 1
* My current Java path are (C:\Sun\AppServer\jdk\bin) in the (User variables for windows).
Please help!!!
Thank you all!!!I'm also windows xp.
fllowing example:
java_home=c:\j2sdk1.4.2_03\bin
classpath=c:\j2sdk1.4.2_03\dt.jar;c:\j2sdk1.4.2_03\tool
.jarThis won't fix a thing.
When you run, do it like this:
java -classpath . HelloWorldNote the "dot" after -classpath. That tells the class loader to look in the current directory for the .class files it needs.
Read about how to run the javac.exe and java.exe tools in your javadocs. You'll have to learn about CLASSPATH. - MOD -
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.

how to set class path for j2me. I downloaded J2ME Wireless tool kit. And set the classpath "set classpath=c:\J2mewtk\lib\midpapi.zip;.;". but i could compile java file. .how to set.
With regards
SanthoshWhen you are downloading j2MEWTK, everything is included within it. You dont require MIDP seperately. When you are runnung the ktoolbar , which is provided with J2mewtk, the preverifier runs and creates the required jad file for you. You dont need a forte to run these.
If you want to download MIDP seperately, that also is possible. Then you have to go for command line arguments. Please refer to Sun's MIDP page for details.
Let me know, if you face any further problem -

How to set classpath to use imported packages?
Hi all,
a real newbie question:
I have created a class in which i import the java.io package. I can compile this class with the Oracle JDeveloper IDE (this is a variation on JBuilder).
The problem is that i can't run this class because (most probably) the java.io package is not in the class path.
Which jar file should i include in my classpath?
jdk1.3\src.jar
or jdk1.3\lib\tools.jar
or jdk1.3\lib\dt.jar
or ...
Where can i find information on this? How can i find structure in the jungle of classes and packages?
thanks, BartIf you want to execute this class file there are two ways you can do this:
First set your environment PATH:
Second you can explicitly state the classpath: for example
change to the directory with the class file:
cd c:\progra~1\Oracle\JDEVEL~1.0\MYCLAS~1
while in the directory type
java -classpath c:\progra~1\Oracle\JDEVEL~1.0\MYCLAS~1 HelloWorld
Hope this helps. -

Starting RMIRegistry in ksh, how to set classpath?
Hi,
I'm a newbie to Unix and have a question. Here's the situation:
I'm
using HP-UX version 11.0 with the latest complete JDK 1.1.7 avail
for
that platform. The shell is ksh. I have a classpath exported
from my
.profile file. I start the rmi registry with the command
"$rmiregistry
&". It starts alright but can NOT find my stub files!
What am I missing? Does the child process I create inherit my
environment settings? How am I or how is the rmi registry
executable
determine the classpath??
Any help would be appreciated.
Frank
nullFrank,
Thanks for your help, but found my problem. I was using an
environment variable that was lowercase, rmiregistry was looking
for it as UPPERCASE!
Thanks,

How to set CLASSPATH with makePropertiesObject in WLST
In Weblogic 9.1 we are using Nodemanager to start the Admin Server in WLST using nmStart. We want to set some memory args for the Admin server and I was told by BEA that you'd use makePropertiesObject to this and pass this object to nmStart, that was fine. We also want to update the admin server classpath and were told makePropertiesObject could also be used for this.
I'm doing
arg = "Arguments=\" -client " + jvm_args + "\""
prps = makePropertiesObject (arg)
nmStart(targetserver, domain_home, props=prps)
where jvm_args ="-Xms256m -Xmx512m -XX:MaxPermSize=128m -Djava.class.path=..."
Also tried
jvm_args = "-Xms256m -Xmx512m -XX:MaxPermSize=128m -cp ......",
However, in both cases the Admin Server process is running with default "-Djava.class.path=...", plus a my "-cp myclasspath" or "-Djava.class.path=myclasspath", depending on which method I used. Am I doing something obviously wrong ? When the Admin Sever is started by NM using nmStart how would you set its classpath ? Should another command be used for starting the Admin Server instead ?Hello,
http://edocs.bea.com/wls/docs91/server_start/nodemgr.html#1083353
This link lists the list of properties that can be specified to start.
Normally, for managed servers, the admin server collects the values for
these properties from various config mbeans and sends them to the
nodmanager. For starting the admin server itself, a properties object
can be created and the values explicitly populated with desired values
and passed to nmStart.
Classpath is one of the properties to send to the nodemanager while
requesting server start.
HTH,

How to Set Classpath in servlet
Hi Friends,
I want to call class with using reflection in my "servlet" , since class which I am calling is stand alone java program and it is not in web application. It is stored else where on server in Offline process. So how can I call the method of this class from my Servlet.
Reply is appreciatedany server when it starts up, loads the classes and lib from specifed paths in a config file.
e.g., jrun has a jvm.config file where you can give the classpath entries for third party classes/jars.
also for the specific classpath entry for particular war-file, u can specify it in the manifest-file of the war. -
How to set classpath to EJB and Servlets
Hi all,
How can I add a classpath to EJB and Servlets in Weblogic 6.1, so that that classpath
can be achieved by both EJB jar and war file? I have deployed a .ear file having
the jar and war files. Now the EJBs inside the jar file are not reaching the class
files of the war file and the class files in the war file are not reaching to
the EJBs. Please let me know at the earliest.
AtanuHi.
You might try looking at the petstore example which combines webapps (war files) with
ejbs in an ear file to see how to do this. It may be a simple config problem.
Regards,
Michael

I would like to know the proper syntax for setting multiple baeans for classpath for iWS6. Can something like this work:
D:/mybeans/beana.jar;D:/mybeans/beanb.jar;D:/mybeans/beanc.jar
thanksHi,
Make sure that you append the following syntax in your jvm.classpath setting in jvm12.conf. And restart the server to make the changes effective. I hope this helps.
<b>D:/mybeans/beana.jar:D:/mybeans/beanb.jar:D:/mybea ns/beanc.jar</b>
