How do I deploy an external JAR file

Hello,
How do I deploy an external JAR file?
I am grateful for every hint.

Hi Manuel,
If you read my blog mentioned in the beginning of the thread, you will note that such solution is not supported in our engine due to number of reasons.
Please, read the blog and use application library shared among these two applications. You will achieve the same effect. Please note that the using application will need run and deploy-time dependencies to the shared library.
You should not add files to any of the folders manually or manipulate engine's classpath in such situations.
Best Regards,
Georgi

Deploying external jar files to the server

Hi,
How can I deploy the external jar files belonging to a simple webdynpro project(no DC) so that it is also available durng the runtime.

There is no direct things to do that. All u need to do is keep the jar files into the lib folder of webdynpro project and also add it from the build-path/classpath by right clicking the project.
1. Go to navigation perspective
2. get into the project\lib folder of the your project. copy the jar files into it
4. right click on the project
5. click on properties
6. click on java build path

Deploying external jar files in CE 7.1

Hi All,
I am using CE 7.1 SP01 NWDS to develop my applications.
Now I want deploy one external jar files to J2ee engine.
I know how to do the same in NWDS 2004s. But here the steps seems to be little bit different.
I referred the following blog for doing this in CE 7.1
/people/raphael.vogel/blog/2008/05/05/how-to-use-external-libraries-in-the-sap-component-model-part-ii
But, still I am getting Classnotfound exception, when i try to use the jar file in dc applications. There, I posted some queries, but I didnt get any solution.
Can any one help me on this please.
Thanks,
Fahad Hamsa

Hi Fahad,
I am facing the same problem, but am not able to get the solution.
I am following the below steps..
1) Created a Webdynpro DC - "testProj" to which i need to add the external library DC.
2) Created a DC of type "External Library" called "externaljar"
3)Added Public Parts of type assembly and compilation to the "externaljar" DC (Component Properties Tab -> Public Parts)
4) Right click on the assembly Public Part name -> Manage entities, and added the JAR files as archive.
5)Right click on the compilation Public Part name -> Manage entities, and added the JAR files as archive.
6)Go to Webdynpro DC "testProj" .
Under Component Properties Tab -> Dependencies tab -> Add -> selected the "externaljar" DC -> Next -> for "externaljar" DC checked Deploy time and Run time.
For assembly Public Part and compilation Public Part "build" is selected by default.
7) I did build of both the DC's and deployed it.
Im getting "Class not found" error.
Please let me know where i am going wrong.
Thanks,
Shilpa.

How to call external jar files in EJB project for CE

Hi,
I would be thankful if someone could help me with this -
I need to call the external jar files into my EJB project - Here is what I have done and am getting runtime exception as -
java.lang.RuntimeException: java.lang.NoClassDefFoundError: com/glance/pdf/pt/PTDoc
1. Created a EJB project" HelloWorld " using Java perspective in NWDS 7.1 called with client as HelloWorldClient and EAR project as HelloWorldEAR.
2. Am working on HelloWorld project (1st one).
3. In my code I am instantiating a class which is a class in one of the external jar file that I need to refer in my project.
4. I have set the Java Build path but it works only for the compile time and fails during runtime.
5. Have read I need to create external library DC and refer in my project "HelloWorld".
Can anyone help me with exact steps what needs to be done - during creation of external library project and then for my "HelloWorld" EJB project. How would I be able to reference or set the external library project in my EJB project?
Looking forward to hear from experts.
Thanks,
Shiv

Hi Edson,
I tried it , but it still gives me runtime exception.
javax.ejb.EJBException: nested exception is: java.lang.RuntimeException: java.lang.NoClassDefFoundError: com/glance/pdf/pt/PTDoc
java.lang.RuntimeException: java.lang.NoClassDefFoundError: com/glance/pdf/pt/PTDoc
Steps I performed are -
1. Created a library project and created 2 Public parts "Compilation" and "Assembly"
2. Build the library project.
Now in my EJB project using Project Explorer - set the classpath and added both compilation jar and assembly jar files.
This is how the classpath entries for external library looks like -
<classpathentry kind="lib" path="/LocalDevelopmentLocalDevelopmentexternallibrarypdftoolsforwatermarkingdemo.sap.com/gen/default/public/WatermarkAssembly/lib/java/demo.sap.comexternallibrarypdftoolsforwatermarking~WatermarkAssembly.jar"/>
<classpathentry kind="lib" path="/LocalDevelopmentLocalDevelopmentexternallibrarypdftoolsforwatermarkingdemo.sap.com/gen/default/public/WatermarkCompilation/lib/java/demo.sap.comexternallibrarypdftoolsforwatermarking~WatermarkCompilation.jar"/>
I have also added the jar files I used in my external library project as "User Library" from Java Build Path . I dont do it , then the code fails during compilation itself.

How to use external jar files ??

Hi all,
In my user-defined function for mapping (IR) , I want to make use a Class which is available in an external .jar file.
Our XI is working on Windows2003 OS. I set the classpath in OS environment variables.
But it is not working.
Where I should set the classpath ?
Can anyone help.
Thanks in Advance
Chemmanz
Message was edited by: Chemmanz

Hi Chemmanz,
For user defined functions, it is not necessary to use the external jar files.
Just follow the below steps:
       1.      To create a new user-defined function, choose <b>Create New Function</b> in the data-flow editor at the bottom of the screen, on the left-hand side.
       2.      Specify the attributes of the new function in the subsequent window:
Name:
Technical name of the function. The name is displayed in the function chooser and on the data-flow object.
Description:
Description of how the function is used.
Arguments:
In this table, you specify the number of input values the function can process, and name them. All functions are of type String.
       3.      In the subsequent window, you can create Java source code:
                            a.      You can import Java packages to your methods from the Imports input field, by specifying them separated by a comma or semi-colon:
You do not need to import the packages java.lang., java.util., java.io., and java.lang.reflect. since all message mappings require these packages and therefore import them.
In addition to the standard packages, you can also specify Java packages that you have imported as archives and that are located in the same, or in an underlying software component version as the message mapping.
                            b.      Create your Java source text in the editor window or copy source text from another editor.
       4.      Confirm with Save and Close.
       5.      User-defined functions are limited to the message mapping in which you created the function. To save the new function, save the message mapping.
       6.      To test the function, use the test environment.
The new function is now visible in the User-Defined function category. When you select this category, a corresponding button is displayed in the function chooser pushbutton bar. To edit, delete, or add the function to the data-flow editor, choose the arrow next to the button and select from the list box displayed.

Hello Raktim
com.sap.security.api should be available within NWDS plugins and should work fine if you add sap-jee DC as used dc.
For external jars check this link

works fine in netwever 7.01 .

Adding External Jar files

Hello,
I have successfully created and deployed a portal application project (par file) that required adding as an external jar the file com.sap.portal.usermanagementapi.jar. Now I am re-doing the project as a development component in NWDI and I can add the external jar file fine and the source code shows no errors. However as soon as I build the DC I get a source error that says the import to com.sap.ip.portal.service.ume.IUserManagementEngine can not be resolved. If I go back to the java build path the usermanagementapi.jar is no longer there.
Do I have to handle the adding of external jar files in a different way for a DC as opposed to a par project?
Thanks,
Bert

Using External JAR file within Web Dynpro DC

Hi,
I have created a Web Dynpro DC and I need to use an external JAR file.
I want to use this external JAR file within the same Web Dynpro DC and NOT creating another DC to house the external JAR file as I can see from the blog.
I have included the external JAR file in the "lib" folder of the Web Dynpro DC.
When I tried to perform a DC build, it keeps complaining error....
How should I solve this problem...
Thanks.

Read images from external jar file (Sun's Java L&F Graphics repository)

Hi!
I don't know how to read images from an external jar file. Sun has a Java Look and Feel graphics repository that contains a lot of good images that can be used on buttons and so on. This repository is delivered as a jar file, containing only images, and I want to read the image files from that jar file directly without including them inside my application jar file. The application and image jar files will be in the same directory.
I have absolutely no clue how to solve this. Is it necessary to include the images inside my application jar file or is it possible to have them separate as I want.
Would really appreciate some help!
Best regards
Lars

Hi,
There is two ways :
1) Add your jarfile to the classpath.
Use the class loader :
URL url = ClassLoader.getSystemResource("your/package/image.gif");
Image im = (new ImageIcon(url)).getImage();
or
Image im = Toolkit.getDefaultToolkit().getImage(url);2)If you don't want to add the jar to the classpath you can use this (under jdk 1.4):
import java.util.*;
import java.util.jar.*;
import java.awt.*;
import java.io.*;
import java.awt.image.*;
import javax.imageio.*;
public class ImageUtilities {
     public static Image getImage(String jarFileName, String fileName) {
          BufferedImage image = null;
          try {
               JarFile jar = new JarFile(new File(jarFileName), false, JarFile.OPEN_READ);
               JarEntry entry = jar.getJarEntry(fileName);
               BufferedInputStream stream = new BufferedInputStream(jar.getInputStream(entry));
               image = ImageIO.read(stream) ;
          catch (Exception ex) {
               System.out.println(ex);
          return(image);
}I hope this helps,

Accessing an external jar file

Hi there,
Does anyone knows how to acces an external jar file?
I need to use a jar on another webserver because the jar is using a library.
Thx...

I think you can add a classpath
in the environment variables on windows
and append the directory of where your jar files
are located.
or
copy the jar files to the C:\j2sdk1.4.0_03\jre\lib\ext
where j2sdk1.4.0_03 is your javahome directory

IO Error while deploying application client jar file ???????

Hi,
In my .ear file, one application-client jar(which contains all helper classes which are used in whole application) file is there. While deploying .ear file, all ejb are getting deployed well, while deploying application client jar file(Global.jar file here) it is giving the following message:
IO Error deploying Global.jar: D:\oracle9ias\oc4j_extended\j2ee\home\applications\trainiumear\Global.jar

My Environment: Oracle9iAS (9.0.3.0.0), Windows-NT
Please let me know Why i am getting 'IO Error' , where i may done wrong ?
Thanks in Advance
Srinivas

Srinivas,
Before we continue, PLEASE tell me if you've looked through the available
documentation, code samples, "how-to" documents, etc., for OC4J. It
seems to me that you're mixing things up a bit. I use the "deploy"
command to deploy my EARs, example (partial):
java -jar admin.jar ormi://<host> admin <password> -deploy ...
And my EAR file is not in the "application-deployments" directory
when I issue that command.
Perhaps you could also show me the contents of your "application.xml"
file for this application you are having trouble with.
But I repeat, please tell me if you have already looked at the
available documents regarding OC4J!
Thanks,
Avi.

How can I get a single jar file with NetBeans?

How can I get a single jar file with NetBeans?
When I create the project I get these files:
dist/lib/libreria1.jar
dist/lib/libreria2.jar
dist/software.jar
The libraries that have been imported to create the project are in separate folders:
libreria1/libreria1.jar
libreria2/libreria2.jar
libreria1, libreria2, dist folders are all located inside the project folder.
I added the following code to the build.xml:
<target name="-post-jar">
<jar jarfile="dist/software.jar">
<zipfileset src="${dist.jar}" excludes="META-INF/*" />
<zipfileset src="dist/lib/libreria1.jar" excludes="META-INF/*" />
<zipfileset src="dist/lib/libreria2.jar" excludes="META-INF/*" />
<manifest>
<attribute name="Main-Class" value="pacco.classeprincipale"/>
</manifest>
</jar>
</target>
Of course there is also the project folder:
src/pacco/classeprincipale.form
src/pacco/classeprincipale.java
Can you tell me what is wrong? The error message I get is as follows:
C:...\build.xml:75: Problem creating jar: archive is not a ZIP archive BUILD FAILED (total time: 2 seconds)

This is not a NetBeans forum, it is a JDeveloper forum. You might want to try http://forums.netbeans.org/. I also saw your other question - try looking in the New to Java forum: New To Java
