Regarding class path setting

Hi,
I am new to java How can i Set a class path in my sytem to run java programs and tomcat and ant .
I declated like below in Environment varialble.
JAVA_HOME
c:\javasdk\jdk\jre\ext;C;\javasdk\bin;
ANT_HOME
c:\ant\bin;
CATALINA_HOME
C:\tomcat\bin;c:\tomcat\common\bin;
when I am running the startup.bat in commandprompt the it showedd me aan error like this.
CATALINA_HOME environment variable is not deffined correctly, this environment variable is needed to run thhis proram.
when I am running the ANT then it showed me an error like this.
build.xml file does not found. But i Wrote the build.xml file in ant\bin.
Please let me know the where is sthe mistake. It is very urgent to me.

I love all these questions that go "I'm really new to Java, so new I don't even know how to set or use a classpath. How do I get my application server to work?"

Class Path, Set Path

Imm new to Java Techology...plz tell me in detail bout how to "Set Class path", ....In Detail...Bye

To set class path
we type
set classpath= c:\j2sdk folder\lib;.;
set path = c:\j2sdk folder\bin;.;
setting these both will work out. in this .; ending means the class path will be available throught otu the command prompt where ever which ever folder it is..
well for setting permanent in the system for win2000 OS
right click on myComputer icon there from that option you select properties
then you get a pop up window where you have few tabs in which last one is advanced -- click on it
then you get there button placed vertically .... in which there is button callled Environment variables
click on it... you will get an window...
in that see the user variables box
In this if there is a variable to see as classpath then append the path of j2sdk folder\lib;.;
if not present then create a variable and set the name to classpath and value to the pathof folder\bin;
similalry path in that also if exist then edit it and give path to bin folder of j2sdk folder..
this will work out for you..

Where is the source or class path setting in 10.1.3.1.0.3

Hello,
Switched to 12 from 11i today.
Very dumb question I guess but I am stuck at this - trying to compile a seeded controller or application module in my project. For example I have
import oracle.apps.ar.cusstd.personalization.webui.CustStdPersonalizationImpl;
in the seeded controller.
The class oracle.apps.ar.cusstd.personalization.webui.CustStdPersonalizationImpl is right under my $JDEV_USER_HOME/myproject
(I also have JDEV_USER_DIR pointing to the same place D:\oracle\jdevr12).
I added
D:\oracle\jdevR12\myprojects
and
D:\oracle\jdevR12\myprojects\oracle\apps\ar\cusstd\personalization\webui
to Project Content but I am still getting
Error(12,8): CustStdPersonalizationImpl not found
Where is the place I should set my classpath?
Can someone help?
Thanks,
Anatoliy

small mistakes happen at times :)

Help Required for Class Path Setting

Plz Inform me How I Set Classpath in DOS Environment.
as soon as Possible.
[email protected]

You don't. Java doesn't run in DOS.
Presumably you are refering to windows.
From the command line
set CLASSPATH=.;c:\mydir
To always set it that way.
-in win 9x use the same 'set' command in the autoexec.bat file which should be in c:\
-in win NT use the start->settings->control panel->system. Use the 'environment tab' The variable can be set either in the user or system space.
For the newer windows they probably use something like the above (probably the second method.)

Hi,
The problem you are referring above is definitely due to the java embedding you are using.
This seems to be a simple Hello World example, and if you are looking for the same to work, you can simply use an assign activity to concat the input with the Hello world.
If you are trying to use a java embedding activity which has some custom java coding in it, please refer to the following:
Make sure all the dependent classes are explicitly mentioned with their packagename.ClassName.
Also , make sure you make all the classes as jar and include it in sca-inf\lib directory of the code.
a) See that your external / dependent Java applications dependent Jar files are copied in csa-inf/lib (e.g all jars like log4j, apache jars, wickets jar etc etc etc )
b) also make sure u deploy the dependent java application as JAR using jdeveloper deploy wizard.... for example archive1.jar and then copy this jar as well in sca - inf / lib folder
it will work ....
Thanks,
Deepak.

Class path problem in Sun Studio Creator

dear,
I have Sun Studio Creator 30 days Trail. i can't compile the EJB Classes. Is there any class path setting in the IDE?. Help me to solve the problem. the EJB class javax.ejb.* package is not found. I am using the deployment server (Sun Application Server 8.0 this could deployed the example files written for EJB. i don't guess what is the major problem.

Lost on the Class Path

I'm having some serious trouble with class package path issues ... ugh!
I've downloaded a fairly complex and well programmed FLA file and other source files in AS 3.0, and just started to adapt it for a custom application. When I published the FLA and packages in FLash CS3, everything worked perfectly. Then I just got Flash CS4 a few days ago, and so opened the same application in CS4, and also published it fine. Yet, once I started to make some very simple customizations, such as create a new MovieClip, and then added "linkage" to the MovieClip in the library, the trouble started. Getting the new external class to associate to the new MovieClip was not working (although it was in the same location as the other package file, with the same class package designation), so of course I went to take a look at the preferences and set the general class path. Interestingly, the class path was completely blank (I just installed CS4 that day). Yet then, why was the application still working initially with no class path set? All of your original classes were loading fine, and the application was working. So, then when I went into actually set a class path (my new class is in the same folder: .../com/parkerandkent/components/classic/photogallery ), I start getting all kinds of errors ... and now, even if I revert back to having no class path at all, the application does not work at all (when it originally did with no class path at all). Strange! I am very confused about what is going on.
There are 5 primary .as package files, all of which are linked to MovieClips in the Library:
ClassicPhotoGallery.as
Photo.as
Thumb.as
Thumbs.as
CallTag.as (the new class)
I've checked the properties linkage for each of these, and they all appear correct also.
Currently, I have all of these class paths set:
- "/Users/mac/_EXTRA/ArtMuse/GALLERY"
- " "/Users/mac/_EXTRA/ArtMuse/GALLERY/com/parkerandkent/components/classic/photogallery"
Currently, I get these these error messages, which are referring to only 3 of 5 total .as files (which are all in the same location, and all have the same class path designation - and none of these files is the new class I made, which now appears to be referenced okay).
Photo.as Line 1:
5001: The name of package 'com.parkerandkent.components.classic.photogallery' does not reflect the location of this file. Please change the package definition's name inside this file, or move the file. /Users/mac/_EXTRA/ArtMuse/GALLERY/com/parkerandkent/components/classic/photogallery/Photo .as
Thumb.as Line 1:
5001: The name of package 'com.parkerandkent.components.classic.photogallery' does not reflect the location of this file. Please change the package definition's name inside this file, or move the file. /Users/mac/_EXTRA/ArtMuse/GALLERY/com/parkerandkent/components/classic/photogallery/Thumb .as

Again, the class path package designation is the same for all 5 .as files:
package com.parkerandkent.components.classic.photogallery {
yet the application is not working, and I get only those errors posted above.
If I remove all source path designations, then I get NO error messages, and yet the application does not work (although, I swear it was working this way originally).

Setting path and class path help

I am a complete beginner who is currently starting a cd based tutorial!I have downloaded jdk1.1.6 which is the nearest developement kit to the one used in the tutorial.I use windows 98.When I try to set my path or class path as instructed in the docs, I cannot find any thing in the autoexec file at all.I have opened using notepad/Run and DOS edit but all three open an empty file.Where will I need to set up the path and class paths.My system must run these from somewhere else perhaps due to an update.

Hi,
Put the following statements in your autoexec.bat.
<homepath> = Path of your JDK folder on the drive. e.g. c:\jdk
SET CLASSPATH=;.;<homepath>\lib\tools.jar; .... continue with other jar files on the same line and seperate the entries by a semicolon.
SET PATH=C:\WINDOWS\;C:\<homepath>\BIN\;
This autoexec.bat must be on c:\. i.e. U can open it in notepad by giving c:\autoexec.bat in the File Open Dialog. It is possible for this file to be empty. Simply add the commands on the last line.
Regards ,
Karan

put ';' and path of the mysql connector jar at the end
suppose if u have jar file under d:/driver/mysqlconnector.jar
thn put this value in variable value text box
;d:/driver/mysqlconnector.jar
or simply put ur driver jar file in jre/lib/ext folder

How to set the class path?-

my forlder is :C:\Documents and Settings\india
jdk is in:C:\Program Files\Java\jdk1.5.0_11\bin
can any body can help me to create a classpath for my folder?

An alternative - as stated in reply 2 in your other thread on this topic: http://forum.java.sun.com/thread.jspa?threadID=5170470 - is not to set the CLASSPATH environment variable at all. Use the -classpath switch instead.
As the documentation linked to in that reply points out: "The class search path (more commonly known by the shorter name, "class path") can be set using either the -classpath option when calling a JDK tool (the preferred method) or by setting the CLASSPATH environment variable. The -classpath option is preferred because you can set it individually for each application without affecting other applications and without other applications modifying its value."
As always, the documentation is worth reading; the available command line options worth using.

How can i set class path in ubuntu JAVA_HOME ?

how can i set class path in ubuntu <JAVA_HOME>?

Note that on *nix
environment variable names are case sensitive.
Also, you are again being vague; is it [this it|http://java.sun.com/j2se/1.5.0/docs/tooldocs/solaris/javac.html] or [that it|http://java.sun.com/j2se/1.5.0/docs/tooldocs/solaris/java.html]

User defined classpath setting using "-Djava.class.path="

Hello,
I am invoking a JVM from a C++ application ( say A ) which inturn will be started by another C++ application ( say B ).
The class path for the JVM is set by "-Djava.class.path=" option in application 'A' which will actually supplied by parent application 'B'.
I want to know how to do it ?
I tried with the following things but it doesn't work.
// the application 'A' gets classpath string from appication 'B' the "classpath" variable ( which is a string ) gets from application 'B'
// this is in application 'A'
// "classpath" variable in application 'A' holds the class path string optained from application 'B'
"-Djava.class.path=" classpath ; ---(1)
// "-Djava.class.path=" %classpath% ; ---(2)
// "-Djava.class.path=classpath" ; ---(3)
All the above tries are failed in first 2 tries the application even doesn't get compiled and in third try the appilcation doesn't set the classpath even though it is get compiled.
Do any one have any Idea !!

Hi,
I am not quite sure if I got your problem correctly...
Your application A has a variable called classpath containing the classpath recieved from B. right? Now you want to call the JVM with that.
I think what you got to do is something like
sprintf(myclasspath, "-Djava.class.path=%s", classpath);
this will build the correct string for the JVM in myclasspath. And that one can be used to call the JVM.
Does this sound right??

How do I set class path for 3rd-party classes?

Hello, I need to know how to set the classpath so that I can use the apache's third-party lang classes. I downloaded commons.apache.org/lang/download_lang.cgi. And I need to know next steps. Move the unzipped files to which location? And type what commands?
Thanks, Melissa

Hi, it's not the server that I am running. My instructor told me to download an apache class file for the Apache Lang library and then set my class path to point to the executable. Her instructions are for Windows users, however. I need to do something in the terminal shell but I don't know precisely what.

OK - I can set the Class Path. Now - what else?

Dear all,
I read with interest the many posts in this forum debating whether to use an IDE for your Java development, or to use some other (more primitive????) means of crafting code - notepad for example. As I understand things:
If I use notepad and the command line to build, run, and compile my classes, then I will hopefully come to learn and understand how to set my class path correctly, and gain an insight into the environment in which I work - an insight moreover, that I might not happen upon if I leave an IDE to do all this for me. Ok - fine, I can use my IDE, but also do some testing on the command line to fill this gap in my knowledge.
If I use an IDE to help me build my UIs, then it is more than likely that I will progress through life without a profound knowledge or understanding of layout managers, cell renderers, event handelers etc. OK - this is fine too, and I have decided to craft my UI 'by hand' because I want a broad appreciation of Swing and anyway, after the initial pain (akin, I imagine, to child birth), it's not so bad really.
Now I feel I am cooking. I understand my environment, and the more esoteric features of Swing; I use my IDE to fashion my code - it's cool and helps me with code completion, and direct access to the API documentation as I type, and it does a whole bunch of refactoring stuff too.
I feel as if I am getting the best from both worlds now.
Would anyone argue against an approach such as this?

ChuckBing wrote:In general, a good approach. You're correct, using the IDE will make life easier.
What you have to watch out for is using it as a crutch. If it ever does something that you can't do, or don't know why it's doing "that", then you aren't learning. The next time "that" has to be done, if the IDE isn't available to do "that" for you, you're dead.
Then you'll be posting the "how do I do that outside the IDE" question here.
Make a promise to yourself: You'll learn why and what the IDE does, and read the API's - A lot!Yes, I agree Chuck. I am not comfortable with a tool doing something for me which I don't understand; which is one of the reasons I build the UIs by hand.
I also become somewhat downcast when I see people in the forums requesting code so they can simply paste it into their aplpications. Learning can be painful, but it is a necessary pre-requisiite to knowledge in my view - so copy/paste can be a most harzardous thing.
I am hoping this thread will be a small guide to new folk.
Thank you for your input,
Steve
