Jar cannot access class of a dependency??

Hi All,
I'm not sure if this is the right place to post but I'm getting a class not found exception. I'm building a test client for db4o and my test uses three classes, two from com.db4o and the other from com.db4o.cs (Client Server). In my test when I call the client server class my program crashes, here's the line
ObjectContainer client = Db4oClientServer.openClient(Db4oClientServer.newClientConfiguration(), HOST, PORT, USER, PASS);I use Maven to manage the dependencies, in this case just db4o, and package as a jar. When I run here's what I get (my project name is Db4oServer)
bash-3.2$ java -jar target/Db4oServer.jar
Running server test...
Exception in thread "main" java.lang.NoClassDefFoundError: com/db4o/cs/Db4oClientServer

        at java.lang.ClassLoader.loadClass(ClassLoader.java:248)
        ... 2 moreWhat I don't get is that the other classes have no problem and I searched the db4o jar and the CS class is in there... ? Please help this is extremely frustrating.

Seems to me like your compile time classpath is fine, but your runtime classpath is not. My bet is that the db4o jar is not on the classpath when you run your application.
You are executing the application as an executable jar; this means that any dependency jars need to be mentioned in the class-path line of the META-INF/manifest.mf inside the jar. This will probably not be the case. So you need to figure out how to setup your pom so this is going to happen; Given the manual page of the jar plugin:
http://maven.apache.org/shared/maven-archiver/examples/classpath.html
I'd say you need to add the addClasspath tag.

PDK 9.0.4 Error: cannot access class oracle.security.jazn.realm.RealmUser

Dear Forum,
we are developing portlets for Portal 3.0.9.8. We use the default JPDK version, that comes with the standalone Oracle OC4J 9.0.4 bundled with PDK.
We want to improve our portlet by check the userid of the portal user. Therefore, we want to use oracle.portal.provider.v2.ProviderUser.getUser().getName()
in a JSP.
First - even before the method call - we included
<%@ page import="oracle.portal.provider.v2.http.ServletProviderUser" %>
But even this 1 statement gives in JDeveloper 9.0.4 with the libs pdkjava and ptlshare from the OC4J the following error:
Error: cannot access class oracle.security.jazn.realm.RealmUser; file oracle\security\jazn\realm\RealmUser.class not found
What is wrong here? What missing library we must include?
Thank You in advance

Problem solved. Need to include jazn.jar in project's lib-paths.

What package do I need to include in my classpath for
this. ThanksWhy don't you inspect your JAR files? Do you have WinZip? Open them with it and find the class.

"cannot access class netcape.plugin.Plugin"

Hello!
I made a project consisting in several Java files, in Jbuilder. The program involves the use og a netscape plugin (a 3D browser). It works perfectly on my computer at work.
When I try tu run exactly the same project at home, i get the error message:
"cannot access class netcape.plugin.Plugin;neither class nor source found for netscape.plugin.Plugin"
Does anyone know what this is about? Please tell me how to solve this problem!
Thank you!

Hi,
Is netscape installed on your computer at home?
The netscape.plugin.Plugin class resides in java40.jar (for Netscape 4.7). Try including it into your classpath.
Hope this helps,
Kurt.

Cannot access class javax.sql.RowSet

Hello everyone,
I had a question about this error I am receiving "cannot access class.javax.sql.RowSet". I have put the RowSet.jar file into my jdk/jre/lib/ext directory and when I compile I recieve this error. Can Anyone help? Thanks!

I think you need to add one (or more) of the available libraries to your project, in your project's settings dialog, but I'm unsure which. If you can't find the correct one, you can always add a newly created one, which holds a reference to your jar file.

Cannot access class oracle.jheadstart.model.adfbc.JhsApplicationModuleImpl;

Error(2,38): cannot access class oracle.jheadstart.model.adfbc.JhsApplicationModuleImpl; file oracle\jheadstart\model\adfbc\JhsApplicationModuleImpl.class not found
Hi,
I am working on demo application from JHeadstart Developer's Guide (ch2). I got the above error when I tried to test the ADF BC.
I checked the Project properties of the model and there was no jheadstart subfolder under oracle folder.
I followed the install.html for JHeadstart download without problem.
I am wondering if the .jar files from JHeadstart that I copied to Jdeveloper is where the issue is?
Any help is much appreciated.
Ahsan

Sandra,
Thanks for your prompt and helpful response.
When you are at page 2-9 in the Getting Started chapter, you should not have run the Application Generator yet, therefore your Application Module should not extend JhsApplicationModuleImpl yet.
CORRECT.
Or did you explicitly set the ADF BC Base Class properties to JhsApplicationModuleImpl?
YES I DID THIS.
The paragraph that describes this does mention that JHeadstart sets it up for you, you don't have to do it yourself. Is that where the confusion originated?
YES I UNDERSTOOD THIS ALSO BUT THE CONFUSION WAS NOT HERE.
MY SUGGESTION: if you modified the first sentence on page 2-10 to something like (You need to 'run the JAG' before you do Right-click the "HRService"Application Module and choose 'Test' 'otherwise you will get an error') would resolve the confusion for me.

Cannot access class java.nio.ByteBuffer

Hi All -
I'm trying to compile a java sample code.
I keep getting the error described in the subject line
cannot access class java.nio.ByteBuffer; file java\nio\ByteBuffer.class not found
I have un-ziped the java sdk 1.4.1 src.zip to a directory under c:\ and added the java\nio directory to the project setting and compile with jdk runtime 1.4.1 and yet get the same error....
I've tried by redirecting to src.zip and didn't work either....
I would appreciate your feedbacks and sorry for the lame question, consider it as a newcomer to Java world.
thanks in advance

You test it by running the following line....
java java.nio.ByteBuffer
If it says "main not found" then your problem has nothing to do with the java install nor the classpath. The code you are trying to compile is wrong.
If it says class not found then you use this line next....
java -version
If this returns nothing then you are not using the Sun VM (you are using the MS one.) If it returns a version below 1.4 then your PATH statement is wrong (and you should uninstall all sun versions then reinstall.) You can fix the MS VM problem by altering the path so the java path is first.
If it does say 1.4 then you need to uninstall and reinstall because something is messed up.

Cannot access class javax.naming.Referenceable;

I am trying to create a connection pool and using the oracle.jdbc.pool.* in JavaBeans using JDeveloper 3.1.
I am getting the following error.Unable to find the reason for this and the sun documentation says - no usage for this class.
Error:

You need to make sure $ORACLE_HOME/jdbc/lib/jndi.zip is on your classpath for this to work.

Cannot access class jclass.util.JCVector

I need the libraries .
Where can I get the libraries for my java application?.
When I compile , I get this error:cannot access class jclass.util.JCVector.
I have been looking for them in the sitraka home, but I haven�t
found any.
I have installed libraries for jclass.bwt. package but I imagine
that it isn�t enough.
Thanks alot-
ras

I dont know the class JCVector, but if you received the error message
"cannot access class jclass.util.JCVector"
It means that the class is there, but you cannot access.
Why I cannot access if the class is there? - you should ask
Problably the access permission of this class is not Public, it must be private or protected.
The most common is the class is protected and it is in another package.
So the JVM locate the class, but cannot access it from your current class, because the class you are trying to access is protected or private.
Hope that i Helped
