About JFM classpath.

Dear ALL,
Any of you have experinece with JFM?
I download JavaTM Media Framework 2.1.1a API
unzip and put it into
C:\JMF2.1.1
My system is win2k
i go to setting----->control panel---> system
---->advance------>enviorment varibles----->system
varibles
set JMFHOME=C:\JMF2.1.1
set CLASSPATH=%JMFHOME%\lib\jmf.jar;.;%CLASSPATH%
but still could not JFMAPI and concerned class
Why? did i set wrong or something else?
thanks for you attention

Is this API a jar File?
do not unzip it
Copy it into the following path
jdk.1.x.x/jre/lib/ext
If this doesn't work try it into
/programs/javasoft/jre/1.x.x/lib/ext
it it exists
Let me know, if it works

Why doesn't my jar file know about my classpath

I have created a simple java program to illustrate my point. My java program is called ABC.java and this is what is in it:
import java.lang.String;
public class ABC {
     public static void main(String[] args) {
          String myClassPath;
          myClassPath = System.getProperty("java.class.path");
          System.out.println("Running ABC\n");
          System.out.println(myClassPath);
          System.out.println("\nFinished ABC");
If I run java ABC.class I get my classpath printed out, but if I create a jar file I do not get a classpath printed out.
I am asking this because I have written a java app that uses a class from a third part jar file that is in my class path. If I run the .class version the app works as it should. If I run the jar version of the app I get a NoClassDefFoundError for the class in the third party jar file.
Since the third party jar file may be in a different path on diferent machines I can not hard code the classpath in my manifest file.
If I use the -classpath or -cp switch when I run the jar file my demo app still does not print the classpath as it should.
I hope this is just a bonehead error on my part.
Thanks in advance.

This suggestion would work well if I only needed to support one OS.
The problem is that under Windows the third party JAR would be in a
subdirectory under "C:\Program Files" but under Linux and Solaris the JAR
file might be in a subdirectory under opt. My relative path would be different
for each OS. It would be great if I did not have to have a JAR for each OS.
One of the great things about Java was supposed to be that you could have
one application that ran under several OSes.
I forgot to mention that for me example above I was using JDK 1.5.0_09.

Q about the CLASSPATH

Just to ensure my classpath is correct ->
CLASSPATH=C:\Documents and Settings\nForce\My Documents\java-projects\com\smith;.;D:\tomcat\common\lib\servlet-api;.
Really my question is, am I correct in seperating the two paths with ";.;"
Thanks

ok I'm sorry for this, but I can't get my head around with what is wrong here..
When I try starting up the j2ee server with the command j2ee -verbose I get the following error:
"'C:\Program' is not recognized as an internal or external command,
operable program or batch file." I don't know why because this is not the standard error you receive when you enter an unknown command into the command line. usually you receive this: "'s' is not recognized as an internal or external command,
operable program or batch file."
I've gone through all my environment variables and I can't match up anything in any of the J2EE settings with "C:\Program"? Could someone help me out here please. I feel like I'm going backwards!!

Confused about CLASSPATH and how java handles import statements...

Hello,
I must admit I don't get it. I read the articles about setting CLASSPATH etc. but I still wonder:
If you use an import statement, what does the compiler do? I.e. where does it look for the specified classes? I find it confusing because I see in different locations different .jar files:
C:\jdk1.3.1_03\lib\dt.jar
C:\jdk1.3.1_03\lib\htmlconvertor.jar
C:\jdk1.3.1_03\lib\tools.jar
and also
C:\jdk1.3.1_03\jre\lib\i18n.jar
C:\jdk1.3.1_03\jre\lib\rt.jar
C:\jdk1.3.1_03\jre\lib\jaws.jar
C:\jdk1.3.1_03\jre\lib\sunrassign.jar
Can someone explain me what the purpose is of these files?
And why do I have the same contents in
C:\Program Files\JavaSoft\JRE\1.3.1_03\lib
and in
C:\jdk1.3.1_03\jre\lib
Why is that?
Thanks for answering my questions!
-mike

Thanx for the answers, but I still wonder, everyone
here says I need to set the classpath, but I don't.Probably because your classes are already in the class path. The compiler/jvm also look for classes by themselves not just in jar files, when just a directory is supplied in the class path. And a period (".") is a valid directory.
Programs importing different classes compile with no
problem. So what's up with that?
Presumably you are referring to your own code - because they are in the class path.
Second, I still don't understand why the runtime needs
the .jar files. The runtime uses classes, like String, that have to come from somewhere.
This would also mean that end-users
need to set the classpath to the .jar files in their
JRE directory to be able to run programs that import
classes from these .jars. But this is not true, right?No it is true. The end-users will have to set the class path. There are variations on this which make it seem like no class path is set. For instance applets in a browser are java but the end-user does not need to set a class path. That is because the browser knows how to download classes/jars and how to set it up so it uses them. (Actually it uses a class loader, but that is probably more information that you need.)
Because if I make some nice classes myself and import
them, how can I expect my end-user to install these
classes and make a classpath for them?That would be between you and you end-user.
First installation is not part of java. For installation you will have to find something outside of java to accomplish the goal.
Additionally how the class path gets set is OS specific. Java does not deal with that. You will also have to find some way to deal with this (most likely part of the installation.)
There are also variations on this. For example the browser example I gave above. Or using the ext directory. Or creating an executable jar. Or simply setting the class path.
In my understanding it should only be needed in the JDK, not
in the JRE. True or am I mistaken?Mistaken. The class path is needed in the JRE as well. You will need to set it.

Classpath inside a JAR file...

Hi there,
I have recently learned that I cannot use my JDBC driver JAR file from within another JAR file. So now I have two JAR files........my application and associated files in one and the JDBC driver in the other.
This gives me......
gatekeeper.jar
ojdbc14.jar
My problem is, when running the application I get an exception stating that it cannot load the Oracle driver. I'm assuming that this is because it cannot find the JDBC JAR file from within the manifest Class-Path.
My manifest is this: -
Main-Class: GateKeeper
Class-Path: ojdbc14.jar commonfiles images
This includes my commonfiles package (all classes) and my images directory. All these things are included. I'm trying to run the gatekeeper JAR file from the same directory as the JDBC driver JAR file.
I've tried: -
Class-Path: ojdbc14.jar commonfiles images
Class-Path: .\ojdbc14.jar commonfiles images
Class-Path: ..\ojdbc14.jar commonfiles images
None of these things help. Obviously I could just specify the JDBC JAR file when running the application using: -
java -cp ojdbc14.jar -jar gatekeeper.jar
....but I want to have the user just run it without having to know about the classpath.....i.e.
java -jar gatekeeper.jar
DrClap said (and I quote) "In the same directory as your main JAR file is easiest, but at any rate the Class-Path entry in your manifest should include the relative path of the driver jar."
...Isn't the relative path to the JAR file outside the JAR this?
.\ojdbc14.jar
Basically, to recap....from within my JAR application file I want to add to the classpath in the manifest file the JAR file that is outside the application JAR file in the same directory. Helpy?
...I'd offer dukes to you fine folks, but I've only got two left. Since I'm such a newbie, I'm not likely to get any more inthe near future, so I'm saving them for a raining day. :) I hope I can get a little charity without resorting to duke bribary. :)

Hmmm...still not joy. This is the exception I'm getting with the stacktrace.

Help me about exporting a project in eclipse???

I have a really basic Java question - I'm building an application using
Eclipse that makes use of a couple of libraries that are located in
external JAR files. I've added them as external JARs( I use the quaqua.jar to set look and feel for my application) to my project, and everything works fine in Eclipse. My programcompiles and access those libraries as expected. However, when I export my project as a JAR file, and try to execute it outside of Eclipse, it gives me an error telling me that it can't find those libraries. The GUI of my application lose,it return to the default GUI of Java application.How
should I proceed? I can import the source code of those libraries into my
project, and then it works fine during export, but it bloats my code and
is really unncessary as I won't be altering any of that code. Is there a
better way (i.e. A way to tell Eclipse to include those external JARs in
my JAR during export, or something?) I would definately appreciate any
guidance, as you have already surmised I am a bit of a beginner at all
this. Thanks!

This is a good example why beginners should not use an IDE until they know about path,classpath and packages. You have to change the manifest file when exporting.

Java Classpath options

My question is about Java classpath options in a production environment.
The company I work for wants to start developing Java applications. These applications will not be running via a web container but standalone on a unix machine. We are setting up the environment and are unsure about the industry best practices. Specifically where it deals with classpath. We have around 15 developers and are not sure how to set up the environment on the production machine so that:
A) The migration process is not overly complex (developers do not migrate/set up the code in production, they develop it and stage it and then other employees move it into production).
B) There is no danger of getting the wrong versions of libraries (for example I am writing code using some toolkit that is version 2 and a co-worker is using version 3 of the same toolkit).
Here is what we have come up with.
1. Require all developers to place their Java code in executable JARs with a MAIN-CLASS attribute and the CLASSPATH attribute set. Here there would be no classpath set on the production environment and each developer would be responsible for setting everything in the jar. One object to migrate.
2. Require all developers to write a shell script to accompany their Java code that will set up the CLASSPATH. This adds programs and adds another object/step to the migration.
3. Just throw all library JAR files in the main JRE class path on the production machine and classes in a /class folder pointed to by $CLASSPATH. This seems like a bad idea and could cause confusion.
4. Require all developers to use custom class loaders in their programs - we do not really understand this method.
Thanks ahead of time for any advice on this issue.

I actually would prefer #2 over #1. I don't like dinking around with the manifest file, and if I want to see what's going on, I find it easier to read a shell script than to pull apart a jar. Plus, even with a jar, you may end up writing a script to set up other environment variables or prepare directories, etc. anyway.I prefer that as well.
The manifest doesn't bother me but with more complex systems, solutions often require something more than just java. Especially for stand alone apps (versus JEE apps.)
Additionally it allows one to control the VM.

but how about the CLASSPATH (with wlconfig.exe)??
Moreover, I can only see some of the above entries in my registry such
as JAVA_HOME, system properties...., but how about the other properties
(e.g. SERVERCLASSPATH), where does it save??
Thanx!
filesdir

But as u can see in my output of running 'wlconfig.exe' (posted on my
last message), there a system property called 'weblogic.class.path',
however, there also exist another entry (not system property) called
SERVERCLASSPATH. What the difference between them (it seems that they have
different values)??
After I entered wlconfig -Dweblogic.class.path=<mypath>, i can only
change the system property (weblogic.class.path), but the entry
SERVERCLASSPATH remains unchanged...
Thanx!

SERVERCLASSPATH == weblogic.class.path
wlconfig -Dweblogic.class.path=<path>
should do the trick.
As for classpath, I thought wlconfig -classpath changed the whole registry
entry. Really doesn't matter that much, you only need to change theprefix
anyway. If you're doing something that requires the whole thing to be
changed, you may need to reconsider...that's a big change.
Finally, SYSTEM_PROPERTIES holds everything else. It's just being parsed
and displayed a little more "human readable".

My autoexec.bat file looks like:
PATH C:\;C:\Win98;D:\JDK118\bin;
SET CLASSPATH=D:\JDK118\lib\classes.zip;.;

First off, dont worry about the CLASSPATH stuff, Sun fixed that in 1.2.
Anyway, you need to see if the ArrayList class is in the class library you used to
compile it, is it in the java.util package? If its not, try looking into other packages.
If it is, try upgrading your JRE version to 1.3 or 1.4
P.S. If I helped at all, I could use some Duke Dollars, please? Thanks alot.

Using additional jars in portal (jregex1.2_01.jar ) and use of javabeans

Hi
I want to use code that parses regular expressions with java and to that end I would like to use jregex1.2_01.jar (if there is a native jar file in oracle that does the same, that woule be good, but I could not find anything that refers to regex or jregex).
I tried to put that new jar file in two locations in the portal area under WEB-INF\lib, namely in:
C:\oracle\ora9ias\j2ee\OC4J_Portal\applications\portal\portal\WEB-INF\lib
where there are a lot of other jar files and also in:
C:\oracle\ora9ias\j2ee\OC4J_Portal\applications\jpdk\jpdk\WEB-INF\lib
However, when I try to compile my code, it fails on the import line:
import jregex.util.io.*;
(the line itself is correct)
Obviously the jregex1.2_01.jar file is not in my classpath, but when oracle was installed, it did not create a CLASSPATH environment variable, so I would not like to make one that may exclude others oracle jars that then are not listed in CLASSPATH.
I have two questions:
1. How does import additional jars into Oracle, so that they can be used by java programs, and are there any inherent dangers in doing that?
2. Where do I place my class file, if I want to use that class file as a javabean. The bean will be referred to by a jsp file which has been imported as a portlet. I assumed I would place my beans under
C:\oracle\ora9ias\j2ee\OC4J_Portal\applications\jpdk\jpdk\WEB-INF\lib
as my jsp files are residing close to that, namely in:
C:\oracle\ora9ias\j2ee\OC4J_Portal\applications\jpdk\jpdk\htdocs\myjsps
but I am not sure.
Can anyone help me with setting up additional jars so they can be used by java files (to be used as javabeans) and with the location and use of javabeans in Oracle Portal?
Any help will be greatly appreciated.
Thanks very much
Hugo

Hi Hugo,
When developing server-side applications, forget about the CLASSPATH environment variable. You must instead become familiar with how the server's classloading scheme operates.
From your post, it looks as though you already are familiar to some degree, because you have correctly identified one of the places to put extra jar files, namely WEB-INF/lib.
At first glance, I would have expected your import to work with the jar file located in WEB-INF/lib - have you made sure you bounced the server?
Also, make sure that any dependencies of jregex are also included in WEB-INF/lib.
Another thing to try is add an entry into ${OH}/j2ee/OC4J_Portal/config/application.xml which explicitly references the jregex jar file.

Javax.mail does not exist

I would like to thank warnerja for your advise about the classpath.
Thanks for the classpath information regarding the .jar files. Now when I start tomcat cat it runs appropriately. However I am still having a problem when i try to compile the message send demo. The message I get is javax.mail does not exist,(import javax.mail.) when I downloade the mail api I placed on the root of my D drive and i placed the mail and activation jar files in my lib folded of my Jakarta-3.2.1 lib folder. I graduated Chubb Institute back in october and am currently still looking for work so my memory but be a little fuzzy as to whether or not this is correct. Your help is greatly appreciated.

If you are just compiling the classes then you should check that the mail.jar file is in your compiler classpath. How you check and set it depends on how you are compiling it and on what system etc.

Bluej package problem

Hi,
can anyone help im trying to get a pakage to work in bluj compiler but keep getting the error package does not exist
this is how the import statement is write the other query I have is do where do I put the package as the package I am using is from killer game programming in java?
import ncsa.j3d.*;

Before you ask "how do I do it" go on google and read all you can find about the classpath, it'll save you time in the future.

Prettier way to do RMI?

I don't like the RMI registry. I think it makes RMI ugly because:
1. Anybody using my application has to start it independently of my application.
2. It requires extra mucking about with the classpath to get my application to work.
3. From my code's perspective, I can't tell if it is running or not until I try to publish a class, and it throws an exception.
4. If it is already running, and someone installs my application, they have to stop it, add my application's jar to the classpath, and start it again, no?
5. (optional, but probable) There's a better way to use rmiregistry, and I'm just ignorant.
So I was wondering if there is a better way to do RMI. I had a couple ideas:
A. At the bare minimum, enable my application to figure out if rmiregistry is running, and if not, configure the classpath for it (somehow... any idea how??)
and start it from inside my application... ...using Runtime.exec()... I guess.
B. What would be better is if I could just include rmiregistry.jar and call methods from it as needed... which would be okay, unless another rmiregistry was already running. And, although I have a copy of rmiregistry.jar, I have no source for it, so I have no idea how to get it going. In fact, I have no idea if the jar I have actually corresponds to a working version of rmiregistry.
... of course, neither of these ideas solves the scenario where rmiregistry is already running, but my application jar was/is not in its classpath.
So does anybody know a better way to do RMI? Or perhaps a simpler way to address the 4 problems I listed?

I don't like the RMI registry.The RMI Registry is an essential part of RMI. Without it to act as a bootstrap, you can't get started.
1. Anybody using my application has to start it independently of my application.No, see reply #1.
2. It requires extra mucking about with the classpath to get my application to work.Not if you do what it says in reply #1.
3. From my code's perspective, I can't tell if it is running or not until I try to publish a class, and it throws an exception.That's how you tell. What's wrong with that?
4. If it is already running, and someone installs my application, they have to stop it, add my application's jar to the classpath, and start it again, no?Not if you do what it says in reply #1.
5. (optional, but probable) There's a better way to use rmiregistry, Yep.
A. At the bare minimum, enable my application to figure out if rmiregistry is running, and if not, configure the classpath for it (somehow... any idea how??)
and start it from inside my application... ...using Runtime.exec()... I guess.See reply #1. Forget about the classpath problem, it disappears.
B. What would be better is if I could just include rmiregistry.jarThere is no such thing.
And, although I have a copy of rmiregistry.jar, I have no source for it, so I have no idea how to get it going. In fact, I have no idea if the jar I have actually corresponds to a working version of rmiregistry.It is almost certainly spurious. Where did you get it? What does it contain? What are the dates?

Need help in installing jmf

Hi friends, i installed jmf-2_1_1e-windows-i586 to c:\programfiles .i need it just to capture image from webcam using java code.I installed it and read the readme about seting classpath and path.i have set it as follows
i dont know whether to change classpath and path from user variables for administrator or from system variables. please tell me
from user variables for administrator my class path has automatically changed to
.;.;.;C:\PROGRA~1\JMF21~1.1E\lib\sound.jar;C:\PROGRA~1\JMF21~1.1E\lib\jmf.jar;
C:\PROGRA~1\JMF21~1.1E\lib;C:\WINDOWS\java\classes;.
and path
C:\Program Files\Sun\jstudio_ent8\ide\uml1\modules\DoorsIntegrationFiles\modules\bin;
i added this to it
C:\Program Files\JMF2.1.1e\lib
and from system variable i added following to class path
C:\Program Files\JMF2.1.1e\lib\jmf.jar;C:\Program Files\JMF2.1.1e\lib\sound.jar;C:\Program Files\JMF2.1.1e\lib\customizer.jar;C:\Program Files\JMF2.1.1e\lib\mediaplayer.jar;C:\Program Files\JMF2.1.1e\lib\multiplayer.jar;.
and to path
C:\Program Files\JMF2.1.1e\lib
and now while compliling the code it says package javax.media does not exists
i have set everyhting as mentioned above
please some one help me

Doesn't jmf set the classpath and path for you. We don't even have to move even a strand of hair. Everything is handled by the jmf.

Adding downloaded third party packages to my application.

Hello!!
I am new to SDN and this is my first post.
I am building a small application and it should have the ability to read a MS Word file from a location.
So I downloaded the Apache POI and extracted it to
C:\Program Files\JavaMy source files are in
E:\Java Assignment\lalaka\filereaderUtil\MSReader.javawhen i try to compile this, i get the error message saying that the package could not be found.
I have searched the internet andfound out about the classpath issue. But I am not clear how to do it.
Do i have to extract the POI files into my source code directory?? how do i get this compiled.
The same issue has pop up regrding java media framework too.
How do i add the functionality of a third party(ex: POI, JMF etc;) in to my applet, and how do i set the class path relevantly.
