External Jar

Hi,
I have implemented reading an XML feed in a Java program using api.
In NWDS, I created a Java Project. And as required added 3 externals jar files.
I had to import the following:
import de.nava.informa.core.ChannelIF;
import de.nava.informa.core.ItemIF;
import de.nava.informa.impl.basic.ChannelBuilder;
import de.nava.informa.parsers.FeedParser;
The program works on run.
when I creat a JSP DynPage and I add the follwoing lines:
<%@ page import = "de.nava.informa.core.* "%>
<%@ page import = "de.nava.informa.impl.basic.ChannelBuilder "%>
<%@ page import = "de.nava.informa.parsers.FeedParser "%>
I get an error: Error occurs during the rendering of jsp component.

Hi ,
But in the case when you are including some external jars, you need to include it both as
"External Jar" and also add it to the lib folder
I hope this solves your problem.
Kind Regards,

How to use one external jar (SDK) for several apps in WTK?

Hi,
I have one external jar (SDK) I use for developing J2ME applications.
Every time I have no choice but to copy this JAR (SDK) into my current application lib directory.
I am building a family of MIDlets that I dont want to put into just one huge JAR but rather to have several JAR files for each application.
In C world I need only to tell the linker where it should pickup ".so" or ".lib" file.
Is any way to do the same with WTK? Or any other J2ME development tool?
Thanks in advance,
Andrew

Link to wtk2.5 beta has been posted to this forum
while ago. It's worth to try it It is MSA1.0
compliant. It has many new JSRs.TomTom,
Thanks again.
I tested the WTK2.5BETA and here I ahve strange fact. My application works perfectly on WTK2.1, WTK2.2 WTK2.3 BETA but it crashes with a very weird message on WTK2.5BETA

So I thought, OK it was compiled under WTK2.1 may it was the reason of crash.
I took sources and compile them under WTK2.5 BETA. I came up with the same result - crash.

Getting error while calling external Jars in BPEL by using Java embedding activity in soa 12c

Hi,
I am trying to use an external Jars for the business logic implementation. Here I need to pass XML as input and
and I expect the "Password " field has to be return.
Following are the steps I have followed:
1) Created a java project with sample class and added the external jars into the project "Libraries &Classpath".
2) Created a jar file out of it.
3) Created a BPEL project with Java Embedding.
4)Wrote the java code in java embedding activity.
4) Added the above created jar file to the BPEL project's lib/jar and added in SCA-INF/lib project folder as well.
5) Imported the package with the class as in the jar (e.g <bpelx:exec
import="pkg.testInterface"/>)
6) Deploy the BPEL project.
while deploying the SOA build is sucessful but my depoyment is incomplete.
error:
advices will be great....
Regards,
Dilip

Hi,
Can you confirm if the BPEL Version is 1.1 or 2.0.
If you are using BPEL 2.0 you need to import the required jar/class file as:
<import importtype="http://schemas.oracle.com/bpel/extension/java" location="pkg.testInterface"/>
For BPEL 1.1 the syntax to import other jar/class file is:
<bpelx:exec import="pkg.testInterface"/>
If you import the classes in the correct format you will not face any deployment error.

Help need in Adding External jar files.

Hi all,
Iam developing ADF application using JDEV 11.1.1.3.0.
I need to move files from one directory to another so i have used external jar "commons-io-1.4.jar" file.
i did this by going to the project properties -->Libraries and Classpath -->Add Library
added the jat file.
In java class i have used the function
File.copyFileToDirectory(reQueueFile, TargetLocation,false);
it was working fine when i tried in IntegratedWeblogic server but when i deploy in Standalone Weblogic server its not getting the jar file.
Its throwing me the exception
javax.el.ELException: java.lang.NoSuchMethodError: org/apache/commons/io/FileUtils.moveFileToDirectory(Ljava/io/File;Ljava/io/File;Z)V
at com.sun.el.parser.AstValue.invoke(AstValue.java:161)
at com.sun.el.MethodExpressionImpl.invoke(MethodExpressionImpl.java:283)
at org.apache.myfaces.trinidad.component.UIXComponentBase.broadcastToMethodExpression(UIXComponentBase.java:1303)
Please let me know is there a way of adding the lib to the project.
Regards,
Suresh kumar.k

First you should check that the library has the checkbox 'Deploy by default' is checked for your library.
The you open the project properties of the view controller project, select Deployments, edit the deployment descriptor. Select the Node 'File Groups'->'WEB-INF/lib'->'Contributors'. this should give you a list of libraries your project uses. Check if your library has the checkbox checked (is selected fro deployment). If it's not checked, set it.
This should include the library.

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 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 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 handle External Jar files in EJB DC

I have created a EJB DC.
I have added the required MDM Jar files to the class path.
These MDM Jar files are supplied by SAP for integration with Master Data Management.
But the DC build fails.
If I create the same project as a REGULAR EJB (non-dc approach)project, everything works fine.
Qn:
How to bundle the MDM jars (External jars)in a DC?
How to create the Public Parts in the DC for the added MDM External Jars?
How to use the above DC in the EJB DC?
Basically, I am looking for a step by step procedure,
to add external jars in a DC.
And to use the above DC in a EJB DC.
Any assistance in this regard is appreciated.

You should not reference the MDM jar files by setting classpath directly. For setting references to it from your EJB DCs , you will have to create a DC of type "External Library". Deploy this DC also before your EJBs are deployed. You will then have to create a public part for this DC and the reference the public part from the DC metadata of the EJB DC ie set the Used DC list of EJB DC to the public part of the ext lib. You will get info about this in NDS help as well on help.sap.com

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

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.)

thanks for you help sidharth.
i have now jar files in the server and the application referring to the jar files. everything is deployed fine. however, when i start the application..i get the error -"package jcifs.smb does not exist". the jar i am using is jcifs-1.2.7.jar. in my web module when i expand the jar i see the package and the .class files inside. what am i missing?
Also, i din't define a SharingReference to usermanagement in portalapp.xml as i am working towards a pure j2ee enterprise application. the web module (DC) referes to the jar files. is there any step similar to defining the sharing reference for the web module DC?

External Jars referencing error

I followed all the following steps which were discussed in forum to referencemy 9 external jars, my DC build was succeded in NWDI and has been deployed onto portal server. I got error message "DeploymentException:Clusterwide Exception:Failed to prepare application.....check the reference....." while running that ear file from portal.
Steps i followed to reference external library:
1) Created externallibrary DC, plces jars and made them as public (here i made one public part for all jars, do i need to create different public part for different jars)...
2) Created library DC and added the above DC as used dc for build time and runtime reference,then deployed onto server i can see the service in visual admin with alljars in it.
3) Created webdynpro DC and added above library DC as used DC, I added library reference tooo, build was succeded and above getting runtime error. Iam giving the exact reference which is copied from visual admin.
I removed the library reference but iam still getting the same error.we running on NW'04s SP8,Any help is appreciated.

External Jars in program

Hello,
Sorry I know it's not an eclipse forum, but I couldn't get answers anywhere, so I hope someone here can help.
I have browsed the net a lot, and found that a lot of people are having similar issues, however I did not manage to make this work .
I have an rcp application which is just a GUI for using my application.
I also have another eclipse java project which has the core classes.
I want people to be able to use either the GUI or directly the JAR file created out of the second project.
Now the troubles :
the second project uses external jars, which I do NOT want to be packaged. I want the users to get those jar separatly and place them in the appropriate folder.
The first one (GUI) uses the second project (well it uses its jar file).
Inside eclipse I can make it work fine, problems come whenever I want to export either the GUI or the JAR from the second project.
What I would like to achieve is the following :
1) If they want to use the GUI, then there is a lib folder in its tree where they have to place all the external jars (and maybe the second project jar too, well I guess)
2) If they want to import the second projet jar in their own application, they have to get the external jars too and place them .... (somewhere? same directory I believe)
Now I have tried everything I found on the net without success : Add External Jars, add Jar, runtime tab, build-path, class-path, Project dependency, manifest etc ... in second or both projects.
I know the solution is somehow in those, but I just can't get it to work. Usually I get export errors on the RCP, sometimes its during execution.
If anyone could explain me step by step what I should do to achieve what I need, I would greatly appreciate it because it's kind of driving me mad.

Don't worry about how many JAR files you end up using. Don't go out of
your way to add JARs unless you know you need them. Typically, you write
code based on what you learn from research and add the JARs you need.
Usually, you won't acquire a lot of unnecessary JARs, but even if you
do, it doesn't hurt (except for a bit of diskspace).
Later, you'll discover which JARs you did or didn't need.
In short, don't worry about this. Just move ahead. You're on the right
track since you chose Java in the first place.

External jars in Web Dynpro for Java CE 7.1.1

Hi there,
Can you give me some guidance for including external jars in Web Dynpro for Java (CE 7.1.1)?
I vainly tried for some hours now to get my external jars running in the new version of web dynpro (part fo Composition Environment 7.1.1).
The routines described in some other threads didn't help me. For example, in CE 7.1.1 there's no DC Metadata that would allow me to add an external library.
FYI, in the error message during build it simply says the package is not found.
My error is javac ERROR: D:\test.jdi\LocalDevelopment\DCs\demo.sap.com\retail\_comp\src\packages\com\sap\demo\retail\javafiles\DomParser.java:12: package com.sap.semprom.retail.sc does not exist
javac ERROR: import com.sap.semprom.retail.sc.BoundEvent;
Thx in advance!
