NoClassDefFoundError after adding third-party jars... need help

Hello SDN! I'm strongly need your help.
I'm developing a WD Java application which contains followed DCs:
AppDC is a Web Dynpro which contains application-depended views, controllers, runnable WD app.
ExporterDC is a Web Dynpro DC with no applications, this is helper DC for export table data into Excel and other formats
MainDC is a Web Dynpro DC with no applications, this is a basis DC. This DC contains some common useful views and controllers which used by AppDC
JavaDC is a Java DC (not J2EE Server Component) which contains my own common helper classes
LibsDC is a External Library DC which contains third-party jars used by apps
J2eeDC is a J2EE Server Component Library DC which is just a wrapper for LibsDC
These DCs has followed dependencies:
LibsDC is Used DC for J2eeDC (both assemble and compile types) with Build-time dependency
J2eeDC is Used DC for JavaDC (defLib) with Build-time and Run-time dependencies
JavaDC is Used DC for ExporterDC, MainDC and AppDC (both assemble and compile types) with Build-time dependency
ExporterDC is Used DC for MainDC (both assemble and compile types) with Build-time dependency
MainDC is Used DC for AppDC (both assemble and compile types) with Build-time dependency
Build perform without errors. I can deploy build results of J2eeDC, ExporterDC, MainDC and AppDC. But when I call my application I get NoClassDefFoundError at row of ExporterDC where is the first call of class from JavaDC which has reference to classes from third-aprty jars.
Please note that I'm not using third-party jars in WD DCs, these jars used only in JavaDC.
I've read quite many threads and blogs but I can't to find solution.
P.S. I'm working with NW 7.0 SP 14, all DCs are local.
Hell will be apriciated!
Regards, Lev

Hi!
Thank you for reply!
Here are few jars in Entities for assembly PP and compile PP in ExtLibrary DC. In "properties" tab property "type" has value "Archive" for every of jar in Entity.
About blog - this blog about situation when Web Dynpro DC use third-party jar. But in my situation Web DC uses Java DC, there is no references to jars in code of WD DC. Only Java DC references to jars.

Accessing third party jars - please help

I have an application that I developed and put in a jar file.
The application will run from the jar file and will run after
it has been signed with a certificate from the signed jar file.
I think I followed all the necessary steps according to the developer
documentation.
When I attempt the use it under webstart it fails with the
following messages.

The classpath in the manifest has "jars/mysql-connector-java-3.0.6-stable-bin.jar"
I signed all the third party jars and they are in a sub directory "jars" under
the directory my jar file is in.
My JNLP file looks like this

I checked the files webstart downloaded and they are all were downloaded.
The code from my program is as follows:
String connectionDriver = "jdbc:mysql://localhost/passport?user=root&password="
Class.forName(connectionDriver); // Load database driverYet I am getting "ClassNotFoundException" as if the program cannot find
the third party jars.
Obviously I am missing something?

Thanks I now have it working.
With your suggestion I added a "jar href"
for each of the third party jars.
It does seem rather stupid to have to do this
as the manifest already has the required information
in it.

NoClassdefFoundError on the third-party jar's classes when building APK

I am building a native extension for Android.
For the android library, I create a android project and add several third-party jar files to build path.
I extract a jar file from a android project and merge it and third-party jar files into a single jar file.
I package ANE using a merged jar file and build a APK.
When I install a APK and launch it, NoClassdefFoundError on the third-party class occurs.
I use Flash Builder 4.6 and set sdk version to the Flex SDK 4.6.0 + AIR SDK 15.0.0.356.
I decompile APK and check the classes.dex.
Strangely a certain jar's classes are missing in the classes.dex.
I tried googling and found a similar case.
The following is the link :
http://stackoverflow.com/questions/24777394/noclassdeffounderror-on-thirdparty-class-files -when-building-adobe-native-extens
I try to follow the answer in this link.
Did dx.jar in the AIR SDK really strip out some classes of third-party jar file??
I inquired the java version of the third-party related with NoClassdefFoundError.
Now I am waiting for the reply.
Is anybody else know about this?

The android-support-v4.jar is same.
I check android-support-v4.jar's classes in ANE.
But they are missing in APK after release build.
I don't know why.
I use Flash Builder 4.6 and Flex SDK 4.6.0 + AIR SDK 15.0.0.356.
Is there anyone else know about this???

Third Party Jars in OIM 11G

Hi All,
I am trying to invoke a web service stub to call create() functionality.
From the stand alone program(with out integrating with OIM server), if I just run it from eclipse, I am able to create the user in target system. If I try to invoke through process task adapters, I am getting Connection Exception.
I think there is something to do with the third party jars. I have copied all the jars to /<Oracle_Home>/Oracle_IDM1/server/ThirdParty and <WEBLOGIC_HOME>Middleware/wlserver_10.3/server/lib.
Should I run "UploadJars.sh" utility of OIM?
Should I update the classpath of OIM and weblogic? I heard that from 11g onwards it automatically pick up the third party jars. Isn't so?
My OIM Server and Target System Application are in different machines. There is no SSL communication. So I think no need to exchange certificates also.
Please help me to solve this.

Hello, oimcoder.
I've removed the jars everywhere (from database and CLASSPATH variable too) besides the ThirdParty folder. When I run my Scheduled task there is a stack trace in log:

Create a JAR including third party JARS

How can I export my project into a JAR file also including the third party JARs being used from my application (project)?
I think Eclipse does not support this, does it?
The problem is, that when I export my project into a JAR and then manually put the required JARs into the JAR using WinZip I do get such an Exception:
java.lang.NoClassDefFoundError: oracle/ucp/jdbc/PoolDataSourceFactory
In my project I have a class (Runner.java) with a main method which the user can invoke from command line. Furthermore I have a GUI also with a main method which internally invokes Runner.java. How can I start either of themain methods/classes both in the same JAR?
Thank you.

hi, i have a question.
i have an application that uses different third party
jars. For the moment i make my jar like this :
a) i include all my third party jars (it is working)
or is it better to
b) include the jars in the jnlp file
this is best, leaving the third party jars alone.
if b is better should i :
b1) link to them to another jnlp file, like this :
<extension name ....
If you app needs all-permissions, it is best to do it this way, you can, for example, sign your jar, and then ask for all-permissions in the main jnlp file, then not ask for all-permissions in the extension jnlp file. Or you can ask for all-permission in the extension as well, if the third party jars are signed, and need all-permissions to run properly.
or
b2) just put them as resources
if you don't need all-permissions anywhere, this is easiest.
If you do need all-permissions everywhere, you could also do this, but you would need to sign the third party jars with the same certificate chain as you signed your jar.
If the third party jars are allready signed by the third party, or if all-permissions are only needed in some of the jars, the b1 is beter.
>
Another question :
i sign my jar, but can't access the local file
system. if i use solution a from above, do i have
also to sign the jars that i include in my jar...
You need to add :
<security> <all-permissions/> </security>
to your jnlp file. In that case, all the jars listed as resources in that jnlp file need to be signed, and by the same certificate.
for solution b i think i will have to sign all the
jars... right ?
yes
Thx for your help/Andy

Unable to access classes in third party jar files packaged with my ejb.jar

I have packaged some third party jar files in my xxx_ejb.jar file. The third party jar file contains classes that are accessed by some custom classes which are in turn accessed by my bean classes. I get the following error when my custom classes attempt to use any of the classes in one of the third party jar files:
java.lang.NoClassDefFoundError: com/Ostermiller/util/CSVParser
Shouldn't I be able to access classes in jar files that are packaged with my xxx_ejb.jar file? I see the xxx_ejb.jar file as a resource of the application classloader that contains it but I don't see the third party jar files.

As per the Java EE specification, additional JAR files should be packaged on the EAR level. Only WAR files' WEB-INF/lib folder is scanned for JAR files to be added to the classloader.

How to include third party .jar files into my jar file

Hi,
how do i include a open source third party jar file into an executable jar?
i have a class called BlogBox.java and it uses org.apache.commons.net.ftp.FTPClient, i want to create an executable file, where do i put the .jar file containing FTPClient aka Apache Commons Net?
currently i'm getting the following error from when executing my BlogBox.jar
C:\MyJava\BlogBox>java -jar BlogBox.jar
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/net/ftp/FTPClient
at blogbox.BlogBox.<init>(BlogBox.java:27)
at blogbox.BlogBox.main(BlogBox.java:103)
Any suggestions? i have searched google and this forum but could not find the solution to my problem, thanks
[edited msg] do i need to add the classpath at execution or something of the apache commons net library?

When you use an executable jar the normal class path
is ignored, but you can put a classpath inside the
jar. The usual trick is to place the library jar
files in a directory inside the application directory
and direct the manifest file to it. The manifest file
live in the jar inside the META-INF directory and
it's called manifest.mf
The two heavilly used entries are Main-class: and
Class-path: lines. Class-path just has a
comma-separated list of library paths.
The jar utility has a special option to load it up.Thanks :) I created a "/lib" directory, placed in the packages in there and redirected the Class-Path: lib/commons-net-1.4.1.jar
and it works,
thank you everyone :)

How to Call third party Jar into Application

Hi Can any Expert help ?
I want to put third party Jar into my application but i have some problem occur.
1. how to call jar with parameter in application ?
2. when i exit the third party jar task, it will exit my main task too. How to set my main tast exit stats standalone ?
3. I have over 10 jar files in one application, how can i set a classpath for client to call JNLP, instread of load all jar to client before run.
Thanks.
Sanki Poon ([email protected])

1) Sounds like you are trying to launch the third party from it's application main instead of using it as an API How does your code interact with it or is that not important?. You don't call a jar, you load a class. You could use a exec http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Runtime.html to run the java launcher and pass it all it's command line stuff(But this may not be possible security wise via WebStart).
2) if it is launched in the same JVM and it calls a System.exit there is nothing you can do about your app closing too. It would need to be in another instance of the JVM
3) Under the resources tag you can have as many jar tags as needed.
    <resources>
        <j2se version="1.5.0" java-vm-args="-esa -Xnoclassgc"/>
        <jar href="/jsf-wita/apps/MathMLWebEditor.jar"/>
    </resources>

How to add third-party jar in CRM ISA application?

Hello SDN!
I need to add third-party jar in CRM ISA application. I know how to add such jars in common case and for local DCs. But for CRM I can't determine which DC should contain this third-party jar.
Please tell me ASAP which DC (e.g. crm/isa/home/ext) I should use.
Help will be appreciated.
Regards, Lev.

Hi,
To add third party jar you need to create new DC which contain your third party Jar. Once you have new DC with your Jar file you can add as Used DC in required DC.
Please refer [Using External Libraries for Development with NWDI|http://help.sap.com/erp2005_ehp_04/helpdata/EN/46/3ce3e4df201d63e10000000a11466f/content.htm] for more infromation to create DC with Jar File.

Deployment (Ejb and third party jars with portal app)

My problem is that I'm trying to set up the development env for a portal project.
I have an ejb and a third party jar in my portal app. My portlets have some java
classes associated with them. The ejb needs to reference(instantiate) the java
classes in the portlets.
Right now the only way I can get it to work is to put the ejb, third party jar
and the portlet classes(jarred up) into the classpath of the server.
I think there should be a way to deploy these things without putting them in the
class path. I've read all the manual sections about deploying.
Can anyone help me with this. It would be much appreciated.
Thanks

Refer to the portal deployment guide
(http://edocs.bea.com/wlp/docs40/deploygd/index.htm). Also refer to

ADF mobile: How to pack a third party jars into apk

Hi Expert,
I am using Jdeveloper + ADF mobile 11.1.2.4 to develop an android application. In this application, I need to call some functions in the third party jar files. I need to add the third party jars into my apk so that those classes can be found during runtime.
I followed section 17.1.1.1 to add the libraries into my project. However, after I deployed my app to the emulator and tried to run it, it reported "encountered error: classes not found". And I also found that the third party jars don't exist in libs/ directory of the apk. Do you know how to solve the problem: How to reference a third party jar files in my app and make sure it works?
Thanks,
Yan

Create a /libs directory within Android project directory and copy the JAR files to /libs.
To build.properties add
external.libs.dir=libs

Question about using third party jar files in Java Web Start Environment

Hi everybody, I got a very strange problem and still can't figer out how to solve it. Can anyone help to overcome this problem?? Thanks in advance.
Question: I wrote a simple java swing application to connect to Oracle database. I packed whole my classes and a third party jar file(classes12.jar) to a new jar file named "IRMASSvrMgntGUI.jar" and then use command 'jarsigner' to signed IRMASSvrMgntGUI.jar. There is no problem when I execute 'java -jar IRMASSvrMgntGUI.jar' in the command line. But when I execute this application via Web Start Environment, an "java.lang.NoClassDefFoundError: oracle/jdbc/driver/OracleDriver
" error occured with the following detail log shown in Jave Web Start Console:

==========================================================================
contents of the manifest file I used to create this jar file are as follows
===================================
Manifest-Version: 1.0
Main-Class: IRMASSvrMgntGUI
Class-Path: classes12.jar
Created-By: 0.9a (itoh)
===================================
and file structures in "IRMASSvrMgntGUI.jar" is
====================================
META-INF/
classes12.jar
DBAuthenticateDialog.class
DBConnection.class
IRMASSvrMgntGUI.class
====================================

If you directly include classes12.jar in IRMASSvrMgntGUI.jar, the classloader won't be able to find the classes inside classes12.jar. You should sign classes12.jar separately and include that in jnlp along with your application specific jar. When you're launching your app using "java -jar somefile.jar" then the classpath settings in manifest file are used, but that's not the case when you start using JWS since in this case the classpath is based only on the " <jar href=..." entries in jnlp.

Packaging a third party jar

Hi,
I need to package a third party jar and export as a jar File using eclipse 3.1? Can you please explain step by step in brief.
Thanks,

The normal way is simply not to do that, but to have the JAR added to the Class-Path entry in the manifest. How Eclipse does that, no friggin' clue. Read the manual.

Eclipse third-party jar inclusion

I really should know how to do this but...
I'm using the Apache jakarta commons CLI package (org.apache.commons.cli)
I had assumed that
import org.apache.commons.cli.*;would work just like
import java.util.Iterator;In that once it compiled, I wouldn't need to worry about where the third party jar file was etc and could distribute my package freely.
Apparently I was mistaken:
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/cli/ParseException
How do I "include" the appropriate information in my .jar file so I don't have to worry about the environment in which the program is run?
java is still my lovely language

This program is a small part of a larger package, and
sits in the same directory as a bunch of other .jars,
each representing one program. It just seemed a little
bit messy to require multiple files for a single
program in this case.
I did review the links, thank you, and have since used
the class-path entry method with multiple .jars as a
workable solution. I'm just not happy with it.Typically when users install software, they run one of those InstallShield (or their competitors) installers. And they have no idea how many files are created or what it does. One file, ten files, a thousand files, they don't really care.
Right now it looks to me like you're wearing both the user hat and the installer hat here, and as a result not doing really well at either hat. You as the user shouldn't care if you have to install three or five files to run the program; to you as the installer it looks messy but compared to most real-life installs it's incredibly tidy. Don't worry about it.
