How to include external .jar libraries

hi,
I'd like to use an external .jar library in my Java program.
I import the package in the source code.
But where do I have to specify the file location of the .jar file. Do I have to add its directory to the PATH environment variable or somewhere else??? So far I've done this only in Eclipse, but now I'm working in a pure linux environment... with no IDE.
Thanks :)

Or specify the classpath completely when you run javac.
For example to compile a class called Foo in the current directory which uses classes from an external jar file I would say
javac -cp .:../../whatever.jar Foo.javaAnd if Foo has a main() class:
java -cp .:../../whatever.jar Foo(If you are working with a number of projects each with lots of classes and lots of (different) jars, it might be time to look at Ant.)

How to include external jars - URGENT...

Hi:
I am using Eclipse for development.
My application uses some external jars.
This step is simple in Eclipse, one simply indicates where the jars are to the IDE.
However, when I make an executable JAR file from my project, those external JARs are not included.
So when I run my program, everything is fine until the parts that uses the external JARs.
Does anyone know how to include them outside of Eclipse platform?
I am going to see my client in an hour and of course I can't bring my source and install an Eclipse at my client's computer to show them my demo...
please help... thanx...

You add those external jars to the classpath or the jars classpath if you're running the program from a jar. Or put the external jar to JAVA_HOME\lib\ext (IIRC)

How to include external files in JSP

hi,
How to include external files like image or javascript in to jsp pages.
I am using MVC frame work. So i have to use request dispatcher. While calling the pages trough dispatcher the external files are missing from the output. Also am using tomcat as server,web.xml(deployment descriptor ) is also configured.
regards
sree

When you use the request dispatcher, the relative path for all your ressources becomes the relative path of your calling serlvet and not the JSP/servlet that you call. Make sure to use the full relative path such as:
/PATH_TO_YOUR_DIRECTORY/myRessource.ext
NOT
SOME_DIRECTORY/myRessource.ext

How to use external jars in NW2004

Hello Experts,
can i use the same approach mentioned in the below Weblog for using the external jars in NW2004.
/people/bertram.ganz/blog/2008/11/24/how-to-use-external-jar-files-in-web-dynpro-development-components
and if not then what will be the best way to achieve it in NW2004.
Please provide your inputs on above.
Regards,
Siddharth

Hi Sidharth,
If you are using web dynpro DC perspective then you need to follow the following points to use the external jar files in it.
1. Create a external library project.
2. copy the external jars in the library folder os the projects.
3.) Select all the jars from the u201CLibrariesu201D folder, Right click and then select Development Component and click on Add to Public Part
4.Select the first Radio Button (Provides an API)and give some nameto it.
5. Repeat the step no 3 but now select the second radio button other than as selected in step no 4.
6. Now build your lirary DC.
7. Now create a j2ee DC project.
8. ) Expand the node DC Definition and Right Click on Used DC. Select Add Used DC.
9. Select the External Library DC with build time dependency.
10.Right click on the J2EE DC and then select Development Component followed by Build
11. Right click on the J2EE DC and then select Development Component followed by Deploy
now you can use both the libary DC and the j2ee DC in your web dynpro DC as used DC.
But if you have created a web dynpro project only(but not DC) than you can directly add the external jars in java build path
hope this will help
regards
Narendra

How to include external style sheet

Hi !!
Can any one explain how to include external style sheet.

Anil,
Simply include the css file as I demonstrated in my last post and then reference one the css classes by name in the "styleClass" attribute of the component. So, if the css file that have included in my JSP file (as demonstrated in the prev post) contains a class like:
.spicyPink {
color:#FF1CAE;
font-weight:bold;
Then I would simply reference this class in the component as folows:
<af:outputText value="Pretty In Pink" styleClass="spicyPink"/>
However, you can also add styling to a component inline and accomplish the same task:
<af:outputText value="Pretty In Pink" inlineStyle="color:#FF1CAE;
font-weight:bold;"/>
The thing to remember is that other than the use of styleClass and inlineStyle, referencing and including css in your JSP/JSPX pages is really no different that used in an HTML page.
Here is reference to help you along:

How to include other jars when using servicegen

I have been trying to use servicegen with regular java classes but I can't figure
out how to include other jars that the webservice class uses?
How is this supposed to be done?

SQL> set null <<NULL>>
SQL> select distinct comm from emp

    COMM
       0
     300
     500

Including External JARs for Java Application in OC4J

Hi Experts,
Here is my requirement.
I have developed my Java application using Tomcat Server & Eclipse. In my application I have used some External JARs & imported the classes in my JSP.
Now that I'm using OC4J Server instead of Tomcat I'v no clue as to where I have copy these External JARs for my application to work.
I have installed OBIEE-Client which includes OC4J server. The path where I have placed my application is as below
*"C:\OracleBI\oc4j_bi\j2ee\home\default-web-app"*
If I run my application the server does not import the classes in the JSP which we include using Import statement using JSP tags (*ex* - <%@ page import = "org.apache.commons.fileupload.*"%>).
This is the location which I found, where I need to put my Java-J2EE application. This OC4J_BI comes with OBIEE.
Kindly help me out on where to place these External JARs exact location in OC4J.
Also let me know if I have to alter any configuration/xml file (if so pls specify the file name & its location).
Thanks in advance,
Venky

You can either include the external libraries in the application, by placing them into WEB-INF/lib, or you can import them into the server as "shared libraries", normally you'd use the "enterprise manager" application to do this. Having loaded a shared library you then add it to the classpath when you're deploying the application.

HOW to include the needed libraries to be copied into the self-cotained app

I'm using: Netbeans 7.2, JavaFX 2.2, JDK 7u7. First, I believe the instructions posted at http://docs.oracle.com/javafx/2/deployment/self-contained-packaging.htm#A1349508 are off (when dealing with NetBeans, at least), as the resulting bundle copies the dependent libraries (3rd party) to the root where the main .jar file is placed, but the MANIFEST gets JavaFX-Class-Path with the lib/ prefix.
This is what I have added to build.xml in the project's folder:
   <target name="-post-jfx-deploy">
        <fx:deploy verbose="true" nativeBundles="image" outdir="${basedir}/${dist.dir}" outfile="${application.title}">
            <fx:application name="${application.title}" mainClass="${javafx.main.class}"/>
            <fx:resources>
                <fx:fileset dir="${basedir}/${dist.dir}" includes="*.jar"/>
                <fx:fileset dir="${basedir}/${dist.dir}/lib" includes="*.jar"/>
            </fx:resources>
            <fx:info title="${application.title}" vendor="${application.vendor}"/>
        </fx:deploy>
    </target>This is the tree structure of the dist folder after Clean and Build Project has been triggered by NetBeans:
│   JFXA.html
│   JFXA.jar
│   JFXA.jnlp
│
├───lib
│       log4j-1.2.16.jar
│
└───web-files
        dtjava.js
        error.png
        get_java.png
        get_javafx.png
        javafx-chrome.png
        javafx-loading-100x100.gif
        javafx-loading-25x25.gif
        upgrade_java.png
        upgrade_javafx.pngAnd this is the structure of the created bundle (conents of the JRE runtime omitted):
└───JFXA
    │   JFXA.exe
    │   JFXA.ico
    │
    ├───app
    │       JFXA.jar
    │       log4j-1.2.16.jar
    │       package.cfg
    │
    └───runtime
        └───jreProblem is, when I run the application (the *.exe* inside the bundle) it tries to run the main *.jar*, but fails due to the inability to locate compile-time libraries. Apparently, this behavior is due to the MANIFEST of the *.jar* being linked to the folder named lib (defaults), but the build script copies the libraries to the output dir where the actual *.jar* resides (dist). How can I fix this? Thanks.
I think I have ran into the same problem as here: javafxpacker - include libs
Edit*:
Upon .jar extraction and further inspection of the MANIFEST file, I see this:
JavaFX-Class-Path: lib/log4j-1.2.16.jar
Currently, as mentioned above, the libraries end up in the root folder where the main .jar resides, due to:
*<fx:fileset dir="${basedir}/${dist.dir}/lib" includes="*.jar"/>*
So, my question is, what do I need to change in order to get the dependent libraries to be copied into the correct path (with lib prefix), when building a bundle? The *<fx:fileset>* does not seem to support anu attribute that would specify the output path structure..

Use
             <fx:resources>
                <fx:fileset dir="${basedir}/${dist.dir}" includes="*.jar"/>
                <fx:fileset dir="${basedir}/${dist.dir}" includes="lib/*.jar"/>
            </fx:resources>or simply
      <fx:fileset dir="${basedir}/${dist.dir}" includes="**/*.jar"/>Filed http://javafx-jira.kenai.com/browse/RT-24757 to update the docs.

How to import external jars in a CAF project?

Hello Experts!
Could you help me find out the way to import external jars in a CAF project. I have tried to import the jars
in ejbmodule using "java build path--->libraries". But while trying to build the project it's displaying error and all the imported jars automatically get removed from the list.
I have read that creation DC of type "External Library" can help me.
1) Create a DC of type external library
2) Copy my jars to folder "libraries"
What should I do next? And how can I import my DC of type "External Library" to my CAF project?
Looking forward for your suggestion.
Thanks & Regards
Vitaly

Hi,
This article will guide you how to deploy the external jar files to the application server.

Including external java libraries in Web Dynpro project

I am trying to include some external jars in my web dynpro project. By including in the project library, the web dynpro app compiles and runs fine.
The issue is that the when I check in the project it doesnt activate in the build environment. What is the best way to include these jars so that the project activate and compiles in the component build space?

Hi Stephen
There are two ways in adding the external JAR files in WebDynpro
1) RightClick on the project - > properties-> Java Build Path - >Libraries ->Add External JAR Files
By doing this , your jar will be available only on the local machine. if the path got changed or file got deleted , you will get errors.so to avaoid that
2) Goto Navigation Tab - > navigate through <b>lib</b> directory and paster your .JAR file there
By doing this your jar file will be deployed on to the sever ,so it will be available always as it is on the server
Best Regards

Problem using Jar to include external jars in an application

Ok so, I've just completed a project, and i want to be able to jar it up so its executable by just using the jar file. I can do this, and it will load the first screen. However, i used eclipse to develop it so I just added two files to the eclipse path and it all worked. But when I jar up my application (and include the two external jars in my app), and try to use any class that needs the external jar, it dies and says java.lang.NoClassDefinitionError: javax/servlet/http/HttpServlet
How do i set it up so it actually finds the classes in the external jar?? Its fairly important that i get this to work :)

If this app is not running as part of Tomcat, you have two options. One, as ejp pointed out, is to put the missing jars into your $JAVA_HOME/lib/ext dir. If you've already tried that and it's not working, then the jars your putting there do not have the necessary classes in them. Use 'jar -tf <jarname>' to see a list of the classes in the jar.
The second approach, which it sounds like you've already tried, is using the Class-Path entry in the Manifest file. You must make sure that the jar you're referencing (servlet.jar) has the missing classes in it, and that the jar is in the same directory as the application jar. Another potential gotcha with this approach is to make sure that the jar is not indexed (they're not indexed by default).

How to use external JARs in Eclipse

Hello.
I created a jar file like that:
jar -cvf0 WarShell.jar WarShell.class
I want to use WarShell.class in Eclipse but it not in my classpath,so I choose [Project] -> [Properties] -> Java Build Path -> Libraries -> Add External JARs and add WarShell.jar to the list.
But when I run the program I got a Exception:NoClassDefFoundError.
Why?How to fix it?
Another question... Your classpath is not available in Eclipse,right?
Thanks for your time! ^_^

If yes, it should work (or seek for an Eclipse-specific forum.)
But if not, keep in mind that your project settings are limited to Eclipse. You'll have to define a correct classpath for running your application.
Another question... Your classpath is not available
in Eclipse,right?Mine? I don't think it is available for anyone ;-P

How to add external jars in the configuration of JSmooth?

Hello,
I am trying to create an exe file from a java program using JSmooth.
The program is a simple hello world proogram.
I am developing under eclipse, and I am using some external jar files as libraries.
If my program is simple,; it works fine. If I add an import of a class that is in one of these jar files, I get the following error when executing the created .exe file:
"Could not find the main class. Program will exit".
I guess I have to add this Jar file to the path for the creation of the .exe file.
My question is: does anybody know HOW to add an external jar in the configuration of JSmooth for the creation of an exe file from a Java program?
Thanks for your help

How to add external jars when deploying webapp via worksop for wls 9.2

While attempting to deploy my web application using Workshop for WLS 9.2, WLS complains it is unavailable to resolve references to a 3rd party JAR(tomhawk.jar) which is being referenced by the JSPs. I have added the JAR via the J2EE module dependancy tab in workshop but that does not seem to be helping the deployment.
If i build the web application outside workshop and include the tomhawk.jar in the WEB-INF/lib folder of the deployed WAR file, the app works fine.
I have attempted to copy the tomhawk.jar into the <domain>/lib folder and restart the weblogic server. But this does not seem to help resolve the references.
Any clues on how i could achieve iterative deployments via workshop for WLS 9.2 pickup references to external JARs being referenced by the JSPs.
Thanks
Ramdas

Raj,
Thanks for your suggestion. The link that you sent out was useful. I was actually able to get the webapp to resolve its references to the 3rd party classes by adding the tomhawk.jar as an external jar via the "build path" property for the web project. I tested this by running the app in the WLS instance hosted by workshop and looks like the JAR from the build path gets somehow referenced during run time too. Not sure how this works?
Thanks
Ramdas
