SHOULD BSF.JAR BE IN CLASSPATH?

I am trying to call a java .class file from XSL. When I include the bsf.jar in classpath, it works fine for me. My question is, do we have to include this bsf.jar in classpath for calling java programs?. Some documents says bsf.jar is for other language scripts only and not for calling java code.
I could not find any relevent documentation in BEA site. Is there any other methods available?
I am using weblogic 6.0 sp2

Deploy the war and the jar files in a ear file. Deploy the ear application file
in the applications directory. Although you could deploy the WAR and JAR files
separately, deploying them together in an EAR file produces a classloader arrangement
that allows the servlets and JSPs to find the EJB classes.

Hi Everybody,
I developed an application consisting in a .war and a .jar
file I
deployed the two files into the weblogic applications directory . When
a run the
application it says that it doesn't find a class, The problem disappears
when
a put the jar file into the startweblogic script CLASSPATH variable.
Is there a better solution, I don't want to put the jar file in the weblogic
classpath
it looks pretty cumbersome.
Thanks

Whichever jars have the classes that you want to use (you should probably put all the jars that you got with this program)
Also, try adding an import statement:
import org.apache.crimson.jaxp.DocumentBuilderFactoryImpl;

Adding a jar to the classpath of an executable jar (mixing -jar and -cp)

Hello,
frankly I hesitated over posting this to "New to Java"; my apologies (but also, eternal gratefulness) if there is an ultra-simple answer I have overlooked...
I integrate a black-box app (I'm not supposed to have the source) that comes packaged as an executable jar (with a Manifest.MF that specifies the main class and a bunch of dependent jars), along with a few dependent jars and a startup script. Long story short, the application code supports adding jars in the classpath, but I can't find a painless way to add a jar in its "classpath".
The app's "vendor" (another department of my customer company) has a slow turnaround on support requests, so while waiting for their suggestion as to how exactly to integrate custom jars, I'm trying to find a solution at the pure Java level.
The startup script features a "just run the jar" launch line:
java -jar startup.jarI tried tweaking this line to add a custom jar in the classpath
java -cp mycustomclasses.jar -jar startup.jarBut that didn't seem to work ( NoClassDefFound at the point where the extension class is supposed to be loaded).
I tried various combination of order, -cp/-classpath, using the CLASSPATH environment variable,... and eventually gave up and devised a manual launch line, which obviously worked:
java -cp startup.jar;dependency1.jar;dependency2.jar;mycustomclasses.jar fully.qualified.name.of.StartupClassI resent this approach though, which not only makes me have to know the main class of the app, but also forces me to specify all the dependencies explicitly (the whole content of the Manifest's class-path entry).
I'm surprised there isn't another approach: really, can't I mix -jar and -cp options?
- [url http://download.oracle.com/javase/6/docs/technotes/tools/windows/classpath.html]This document (apparently a bible on the CLASSPATH), pointed out by a repited forum member recently, does not document the -jar option.
- the [url http://download.oracle.com/javase/tutorial/deployment/jar/run.html]Java tutorial describes how to use the -jar option, but does not mention how it could play along with -cp
Thanks in advance, and best regards,
J.

Ahem, the "Java application launcher" page bundled with the JDK doc (http://download.oracle.com/javase/6/docs/technotes/tools/windows/java.html) specifies that +When you use [the -jar] option, the JAR file is the source of all user classes, and other user class path settings are ignored+
So this behavior is deliberate indeed... my chances diminish to find a way around other than specifying the full classpath and main class...

I would have thought that the main-class attribute of the JAR you name in the -jar option is the one that is executed.Then I still have the burden of copying that from the initial startup.jar's manifest. Slightly less annoying than copying the whole Class-path entry, but it's an impediment to integrating it as a "black-box".
The 'cascading' behavior is implicit in the specification
I know at least one regular in addition to me that would issue some irony about putting those terms together :o)
Anyway, thank you for confirming the original issue, and merci beaucoup for your handy "wrapper" trick.
I'll revisit the post markers once I've actually tried it.
Best regards,
Jérôme

Adding Classes to the JAR File's Classpath

Ques 1- Can I use the wildcard * symbol in Manifest file to add classes/othes jar files to the JAR File's Classpath.I have folder named - Lib . where there are many jar files.Now,do I have to add each jar file by- Class-Path: Lib/jar1-name Lib/jar2-name . Instead, can I do this- Class-Path: Lib/*.jar OR Class-Path: Lib/*.class

Adapter jar file in classpath ?

Hi All,
          Is it still a requirement to put the adapter jar file in classpath for the
          adapter developed using ADK in WLI2.1 and WLS6.1SP1 ?
          coz if I dont put it in the classpath, then its not able to find the message
          bundle files (.properties and .xml) !!
          Thanks
          Amit


then i created a jar file named darshan.jar with following command :
jar -xvf d:\darshan.jar darshan/*.classThat command doesn't create a .jar file, it extracts files from an existing one. You need to use c instead of x to create a new .jar file:
jar -cvf d:\darshan.jar darshan/*.class

How do you add a jar to the classpath?

I'm trying to load a driver for MySQL, but the program doesn't seem to find the driver. I get an exception everytime. I keep seeing references about adding the jar (mysql-connector-java-5.1.6-bin.jar) to the classpath, but I don't know how to do that. Also, do I only that the jar, because there are other files along with it (src, com, etc.). I'm running Windows XP and using Eclipse.
import java.sql.*;
public class Driver {
     public static void main (String[] args) {
          try {
               // Step 1: Load the MySQL driver.
               System.out.println("BP01");
               Class.forName("com.mysql.jdbc.Driver");
               System.out.println("BP02");
          } catch (Exception e) {
               System.err.println("Got an exception! ");
               System.err.println(e.getMessage());
}

In Windows Explorer or the Command Prompt, try changing your directory to what the message about not finding the JAR in the repository says (C:\Documents and Settings\xxx\Desktop\mysql-connector-java-5.1.6\) and verify that something called mysql-connector-java-5.1.6-bin.jar! exists there.

Did u use jar files as classpath for appletviewer?

as tested, jar files can not be used as classpath for appletviewer.
java command is bellow
appletviewer -J-classpath -Jc:\folder00\some.jar; -Jc:\folder01\any.jar; MyAppletClass
the jar files (or classpaths) above do not work.
I am not sure about my test, so i post my Q here for confirming it.
thx

appletviewer needs HTML code to run an Applet similar to how the Applet would be run from a browser. It does not have a Classpath option.

Execution from JAR files and Classpaths -- Help

I am confused about how classes are resolved when running from within a JAR file, and why this is different than running a class that is not inside a JAR file.
I have an application that uses classes from a third party library stored in a JAR file (biojava.jar) . If I run the app from the class file it works as expected and is capable of finding the external classes when the path to the biojava.jar is on my classpath. It also works if biojava.jar is instead placed in the extensions folder jre/lib/ext folder without an explicit path entry in my classpath.
However when I package all my application classes up in a JAR file and try to execute the application from the JAR file it will ONLY work if I add a manifest entry to myApp.jar ... Class-Path: biojava.jar AND I place the file biojava.jar in the SAME directory as the Packaged JAR application. I would like to find a way to make this JAR file work for anyone who has biojava.jar in their classpath or ext directory. In other words I don't want my user community to have to copy the biojava.jar file when I email them myApp.jar. This community will already have biojava.jar on their CLASSPATH.
How can I make my app within a JAR recognize either the user's CLASSPATH or ext folder? I have tried reading the documentation and many experiments but the only way it works is as described above.
I am running Running Windows 2000.

Thank you very much for any help or suggestions,

I did some more testing and I think I now understand what is going on.
I don't like it, but at least I understand it.
The problem: I have an app packaged into a JAR file, myApp.jar. It has a dependancy upon an external JAR file extern.jar.
extern.jar is on my Classpath (and also in jre/lib/ext)
1) For some reason (bug?) java -jar myApp.jar does NOT use the classpath or the jre/lib/ext mechanisms to find .jar files needed to resolve references to external classes. This seems to be true even if you add an explicit -classpath argument on the command line!
thus
java -jar -cp c:\\absolutePathToMy\extern.jar myApp.jar
also fails as does
java -cp c:\\absolutePathToMy\extern.jar -jar myApp.jar
2) Inside the myApp Jar file you can specify a URL to an jar extension jar file but the URL IS RELATIVE TO THE PATH WHERE THE myApp.Jar is executed from! If I add the Manifest item Class-Path: ..\..\..\myexterndir\extern.jar then
java -jar myApp.jar
works correctly and resolves the external references.
This is why several people have reported that this class-path mechanism works ONLY when the extern.jar file is in the SAME DIRECTORY as the myApp.jar file when they had added a Class-Path: extern.jar to the Manifest.
However together these two items make it IMPOSSIBLE to distribute myApp.jar to others and have it work since the path names statically encoded inside the jar are relative to where the jar gets executed from. If I move myApp.jar to a different location on my hard drive it may also fail.
In my case I know all my customers already have extern.jar (5MB) installed on their classpaths and I would like to just send them the myApp.jar ( .5MB ).
However I don't see how to do this given the current specification of a JAR file, and the bug that makes all -jar file act like they have the Sealed=true property.
I tried explicity setting Sealed=false in the manifest but this didn't seem to have any effect.
I hope that this will save others the many hours of time it has taken be to determine that JARS are not well suited for deploying apps with dependenncies on external libs.
I also hope that someone can show me how execute a JAR and specify a classpath that doesn't get IGNORED my the classloader used in loading the jar classes.
This is using java version:
java version "1.4.1_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_01-b01)
Java HotSpot(TM) Client VM (build 1.4.1_01-b01, mixed mode)
Does any one know this bug is fixed in a later release?

Webapp: ejb jars on servlet classpath

          I have created a WebApplication (using WebLogic 5.1 sp8) that uses
          the directory structure documented in http://www.weblogic.com/docs51/classdocs/webappguide.html#dirstruct
          (with a web-inf/classes for servlet classes and web-inf/lib for
          ejb jars)
          According to http://www.weblogic.com/docs51/classdocs/API_ejb/EJB_deployover.html#1056431
          , the public interface of my ejb's should be exported to the weblogic
          classloader so that my servlet can use these classes when doing
          remote calls.
          When I run the weblogic console and check my web application's
          servlet classpath however, I see that all jar files in web-inf/lib
          have been included. So now my servlets have access to not only
          the remote interface, but the entire implementation of my ejb's!
          This is not what I want, or what should happen according to the
          documentation.
          Is there something I am doing wrong, is this a weblogic bug, or
          is the documentation just wrong?
          Luke Hutteman
          Bank of America


In 5.1, ejb classloader will export public interfaces to weblogic
          classloader automatically. And servlet can access those classes since
          weblogic classloader is the parent of servlet classloader.
          So, you do not need to pack your ejbs in jar and put them in WEB-INF/lib.
          However, for application exception classes and other classes used by your
          ejb, you have to pack them, either put them in weblogic.class.path or
          WEB-INF/classes or WEB-INF/lib (as jar file)
          My 2 cents.
          Cheers - Wei

Where should a ".jar" file be placed?

Hey.
I know there's a jar (java archives) forum, but things are kinda slow over there...
I'm trying to run a simple JDBC application using Cloudscape (I've downloaded cloudscape.jar for that) and jdk1.3.1, on LINUX.
The new .jar file isn't recognized and I keep getting a runtime ClassNotFoundException.
I've changed several system-files (such as the root's .tcshrc and my own .bashrc), and copied the file almost everywhere, but just can't get it right :-(
Where should the cloudscape.jar file go, and what are the exact changes needed in order to force (no more mister nice-guy) the system to acknowledge it?
Thanx,
Mike.

just make sure your CLASSPATH includes cloudscape.jar. Not just the path, but also the jar filename.
There is also a jre/lib/ext path in your java installation where you can dump your jar file so it will automatically be seen when you run your program.

Jar file and classpath problem

I0m writing a program that use the kunststoff.jar Look&Feel.
Now I would like to put all I'm writing into a jar file but I always have a NoClassFoundException when I try to start my application.
here is a MANIFEST:ME I'm using:
Manifest-Version: 1.0
Created-By: 1.4.2-beta (Sun Microsystems Inc.)
Main-Class: JListaR.JListaR
Class-Path: kunststoff.jar img\ .why this don't work?

Unfortunately you can't embed jars within a jar and
expect them to be referencable for the classpath from
outside the main jar. The "Class-Path" attribute in
the manifest is used to refer to other jar files
outside of your jar file.
The usual approach to solve this problem is to unpack
the jar files you want to embed and then rejar
everything together in one big jar file again. This
isn't always a great approach though, I know I'm
looking for an alternative. So far my only alternative
is dynamic class loading using a classloader, however
this isn't great if you need to refer to several
hundreds or even thousands of classes.thank you very mach...now I understand because it dosen't work correctly!

Classes+resources in JAR: have to add each single Jar file to CLASSPATH?

Hello,
For my application, I plan to easily embed plugins that can be added by the user by copying it into a subfolder "plugins".
Now, I start my app from a shellscript and in order to load resources from within some of these Jars (e.g. using Class.getResourceAsStream() ), it only works if I explicitly add the specific Jar filename to the classpath from the shellscript.
I read in a German Java book, that also just using folder names is enough, but it does not work for me:
Works:
$JAVA_HOME/bin/java -Djava.library.path="./lib" -classpath "./lib:./plugins/test.jar" test.AppFails:
$JAVA_HOME/bin/java -Djava.library.path="./lib" -classpath "./lib:./plugins/" test.AppIs it really required to add Jars explicitly, so that e.g. my shellscript has to make a Jar listing of that folder in order to pass them as classpath files?
Thanks and regards,
Timo

No, you don't have to do it that way. What you need
to do is to have your progam create a URLClassLoader
pointing to all the jars in the plugin directory.
Then request your plugin classes from that, rather
than Class.forName();
You need to create an array of file URLs for the
jars, use File.listFiles() and then File.toURL() on
each ..jar you find.
p.s. If you do it this way make sure your plugin
classes are not on the classpath.
Hmm. Cool. I had no idea. Thanks for correcting me.
