Class not found in import

I am new to the Java technology and am running into some problems getting started. Initially, I was getting the following error: Class javax.swing.JOptionPane not found in import. After realizing that I needed to unzip the src.zip file, I did so. I tried compiling again and got the same message. I came across a website that talked about setting the CLASSPATH. So I set the class path like so: set CLASSPATH=.;C:\;c:\j2sdk1.4.2_04\src;. Finally! I got passed the first error. However, what followed was quite depressing. 50 Errors! Looks like the compiler can not find any class I import that starts with "sun.". I looked where I can see the javax folder and there is no sun folder. Did I miss something in the installation? Is there a workaround for this? I thought I read somewhere that you shouldn't import sun.* classes, but what happens when it is in the delivered packages? TIA Ryan

Well to start off... The file Src.zip only contains source files nothing compiled so it useless unless you want to look at the source code, the Java Class files are in a "Jar" file...
Set your (system) path to c:\j2sdk1.4.2_04\bin
your ClassPath should only point to the new class files that you created...
( I don't even have the ClassPath set on my computer)
And this link deals with setting the classpath...
http://java.sun.com/j2se/1.4.2/docs/tooldocs/windows/classpath.html
That should take care of it... Here are some links for you to check out...

Error Class Not Found when Importing

When trying to import the roles from SAP, the Tomcat server throws the following error:
20-04-09 10:26:28:662 - [/SAP].[Faces Servlet] Thread [http-8080-Processor23]; Servlet.service() for servlet Faces Servlet threw exception

I have added the sapjco.jar to the classpath of tomcat server and restarted the service. But it seems to have no effect.
Would you have any proposed solution?

Hello Ingo.
I install the new jco version 2.1.8 by replace the old version.
- Replace sapjco.jar in /<BO DIR>/bobje/tomcat/shared/lib .
- Replace librfccm.o and libsapjcorfc.so in /<BO DIR>//bobje/enterprise120/aix_rs6000 .
then stop tomcat and redeploy the application using this script below.
./wdeploy.sh tomcat55 -DAPP=CmcApp -Das_admin_password=root1234 undeploy
./wdeploy.sh tomcat55 -DAPP=CmcApp -Das_admin_password=root1234 deploy
./wdeploy.sh tomcat55 -DAPP=InfoViewApp -Das_admin_password=root1234 undeploy
./wdeploy.sh tomcat55 -DAPP=InfoViewApp -Das_admin_password=root1234 deploy
./wdeploy.sh tomcat55 -DAPP=OpenDocument -Das_admin_password=root1234 undeploy
./wdeploy.sh tomcat55 -DAPP=OpenDocument -Das_admin_password=root1234 deploy
./wdeploy.sh tomcat55 -DAPP=dswsbobje -Das_admin_password=root1234 undeploy
./wdeploy.sh tomcat55 -DAPP=dswsbobje -Das_admin_password=root1234 deploy
./wdeploy.sh tomcat55 -DAPP=SAP -Das_admin_password=root1234 undeploy
./wdeploy.sh tomcat55 -DAPP=PartnerPlatformService -Das_admin_password=root1234 undeploy
./wdeploy.sh tomcat55 -DAPP=SAP -Das_admin_password=root1234 deploy
./wdeploy.sh tomcat55 -DAPP=PartnerPlatformService -Das_admin_password=root1234 deploy
Then I have the new problem.
After I start tomcat I logon CMC as administrator then click Authentication.
I switch 'Entitlement tab' into 'import role' tab I got this error.

Did I miss something?
Please give me some advise.
Thank you.

Compilation Error for import classes not found in generated Proxy Class

Hi,
We are generating java classes for the COM dll using JCOM com2java compiler.
We are getting a compilation error for import class not found when compiling the
generated Proxy java source code. It can't find the com.bea.jcom.Dispatch class that
the generated Proxy java source code extends. It also can't find com.bea.jcom.Variant
or com.bea.jcom.Param. These are interfaces or data types or classes used by COM
library.
I added weblogic.jar to my class path and the only Dispatch class i found inside
the weblogic.jar is com.linar.jintegra.Dispatch;
We have com objects for which we want to develop an EJB client to interface with
the COM object using JCOM with Native Mode disabled.
Any help on the compilation error..I tried changing the extends for Dispatch to com.linar.jintegra.Dispatch
but the other errors are still there.
To begin with, I think the generated code should not refer to any of the COM data
types.
Any help please.
Thank you in advance,
Regards,

Hi,
I resolved the other errors by changing all references from com.bea.jcom.Variant
etc to com.linar.jintegra.class name..all were present under the com.linar.jintegra
package.
Thank you all anyways,

Appreciate some pointers on how to troubleshoot this problem. Thanks. William Chew.

This error is due to the c:\windows\system32\java.exe being first on the path instead of the d:\jdev9i\jdk\bin\java.exe being picked up.

Class javax.crypto.SecretKey not found in import.

While compilation i am getting this error.
Class javax.crypto.SecretKey not found in import.
I am not able to figure it out . Please help me for that.
Is it related to some classpath setting.

This error is due to the c:\windows\system32\java.exe being first on the path instead of the d:\jdev9i\jdk\bin\java.exe being picked up.

I installed the jdk1.4 on my workstation. I then compiled the program via JDeveloper and pumped the class over to my server.
Thanks again.

Package zzz not found in import (server side classes)

          Hi,
          I'm trying to use the "Web Application" feature in WL 5.10
          (with no service pack). My application contains a couple of
          servlets, a couple of server side classes, and a couple of
          jsp pages.
          I created the WEB-INF\classes directory structure both in
          public_html and in my application's root directory. I
          modified setEnv.bat to contain the two directories in
          ClassPath and compilation of my servlets from the command
          line completes OK (the servlets import a package that sits in
          public_html\WEB-INF\classes).
          However, when I try to import the same package from a jsp
          file, I get the "package zzz not found in import" error
          message. The trace shows that the java compiler invoked
          after the servlet has been generated does not contain
          public_html\WEB-INF\classes in the ClassPath, but contains
          public_html\my_app\WEB-INF\classes.
          How can I specify that the java compiler should look under
          public_html\WEB-INF\classes for server side classes? Is there
          another solution and am I even using the right approach?
          Thanks,
          Vladimir

          You should install the service packs, your problem will probably
          disappear then.
          Web Apps are better supported with service packs.

How can i configured my system
I have Windows XP
[email protected]

try compiling like this:
java -cp "." myTest
This is not compiling, here you execute the already
compiled myTest.java file (or it should be already
compiled). To compile you may want to use javac or any
other available compiler.Oops, sorry, I didn't mean compiling.
If you were able to compile ok, you can try running the program by using:
java -cp "." myTest
This usually will solve the problem when your program comples fine but can't find the class when you try to run it. It's almost like the compiler assumes to look in the current directory but the VM (java.exe) doesn't make this assumption.

Class not Found when accessing Proxy class from backing bean in VC.

Hi All,
I'm attempting to access a class of a webservice(generated as a proxy) within my ADF application and invoke the method within a backing bean of the View Controller(bean scope : backing bean). The proxy has generated an ObjectFactory class among other classes. When I access this Object factory class from within the backing bean, the application throws a Class not found error.
I don't know where the error lies since I've declared the View Controller of the ADF application dependent on the Proxy and I've imported the class and accessing it within a backing bean. How would you suggest I approach resolveing this.
JDev : 1.1.1.4
Thank you.
Regards
PP.

Hello Arun,
Thank you for suggesting a Data control, but my requirement isn't to drag and drop the method as a button. It's more of a behind the scnes updating data via a database adapter requirement.
I've resolved the issue. turns out, my deployment archive didn't include the proxy.jpr. Once included it works likea charm.
Thanks
PP.

Not able to start the remote server - class not found exception

Following are my classes:
MyRemoteInterface.java
import java.rmi.Remote;
import java.rmi.RemoteException;
public interface MyRemoteInterface extends Remote {
public String[] getNames() throws RemoteException;
public class MyServerImplementation extends UnicastRemoteObject implements
MyRemoteInterface {
public MyServerImplementation()throws RemoteException{

public String[] getNames() throws RemoteException{
return new String[]{"Name1","Name2","Name3","Name4"};
public static void main(String args[]) {
try {
// Create an object of the HelloWorldServer class.
MyRemoteInterface obj = new MyServerImplementation();
// Bind this object instance to the name "HelloServer".
Naming.rebind("rmi://localhost:1985/GetNames", obj);
System.out.println("GetNames bound in registry");
catch (Exception e) {
System.out.println("GetNames error: " + e.getMessage());
e.printStackTrace();
public class MyRMIClient {
*@param args*
public static void main(String[] args) {
try {
MyRemoteInterface remObj = (MyRemoteInterface) Naming.lookup("rmi://localhost:1985/GetNames");
System.out.println("Names are "+remObj.getNames());
catch(Exception e) {
System.out.println("Problem encountered accessing remote object "+e);
}

That's a remote exception coming from the registry. You need to learn to recognize remote exceptions and their source, it's a mjaor source of confusion in RMI.
In this case it's the registry that can't find the stub class.
The stub class needs to be in the CLASSPATH of (i) the Registry and (ii) the client as well. Ditto the remote interface; ditto any application classes it refers to, and so on until closure.
The easiest way to achieve (i) is to start it in the server's JVM, with LocateRegistry.createRegistry().

/usr/sap/X7R/DVEBMGS41/j2ee/cluster/server0/./temp/classpath_resolver/Mapcedceb44283d11e0c032000018b99fca/source/com/sap/xi/tf/_MM_test_.java:81: cannot access javax.xml.datatype.XMLGregorianCalendar bad class file: /usr/sap/X7R/DVEBMGS41/j2ee/cluster/server0/./temp/classpath_resolver/Mapcedceb44283d11e0c032000018b99fca/classpath/IA_javax_2.jar(javax/xml/datatype/XMLGregorianCalendar.class) class file has wrong version 49.0, should be 48.0 Please remove or make sure it appears in the correct subdirectory of the classpath. XMLGregorianCalendarImpl XMLGenTime = new XMLGregorianCalendarImpl(gentime);
Kindly help me to solve this problem.
Thanks,

I have found the solution.
The problem is solved by adding jaxp_api_1.3 jar and jaxp-ri-1.4.1.jar.we have to have both these jar in PI 7.0 to use com.sun.org.apache.xerces.internal.jaxp.datatype.XMLGregorianCalendarImpl package
Thanks

Error in beanshell - class not found in namespace

We use beanshell to evaluate business rule validations on our application. Below is the calling method...
private Object callBeanShell(final Object parameters, final String expression)
throws EvalError {
if (LogConstants.FINE_ENABLED) {
logger.log(Level.FINE, "Expression: " + expression);
beanShell.set("params", parameters);
Object result = null;
try {
result = beanShell.eval(expression);
} catch (Throwable ex) {
getErrorHandler().fatalError("Expression: " + expression, ex);
if (LogConstants.INFO_ENABLED) {
logger.log(Level.INFO, "Expression: " + expression);
logger.log(Level.INFO, "Result : " + (result == null ? "null" : result.toString()));
return result;
This has been working fine on the application for years, but we've suddenly started getting a problem with evaluations which are called from a SessionBean (via some reflection).
Every time we try and call a certain set of expressions they fail on a 'class xxx not found in namespace'. This happens both when the expression contains code like:
com.chubb.euz.SomeClass sc = new com.chubb.euz.SomeClass(); etc...
or
import com.chubb.euz.SomeClass; SomeClass sc = new SomeClass(); etc...
The strange thing is that when I remote debug it & look at the bsh Interpreter what I see is that it's NameSpace object has a table called ImportedClasses on it which before the eval() call contains just bsh.Interpreter and bsh.EvalError but after the eval() it then contains all of the classes I pull in as imports in the expression passed to it, yet it still manages to throw this damn 'class not found in namespace' error!
It still works whenever else it's called in the app (and this is only happening in our DEV environment). All I can think of now is that it's possibly something to do with the Thread that the beanshell is running on at this time, but that's just a guess as I know bugger all about Threads... I only think this because I can get the thing to work by stopping the processor which was built to run Events (EJB) generated in the app; resetting the Event's Task (regular class) to run again; then restarting the processor (not an option if this goes into PROD with the release!!!)
Unfortunately, re-factoring the validations we need to run at this point is not really an option, as this is all coming at the tail end of a new release & the amount of code changes & subsequent regression testing required would kill us.
This is on weblogic 8.1 - with the beanshell jar just embedded in the main application ear (I ran it with bsh.20b4.jar instead of the 1.3 version we were using but that has no effect).
Any ideas would be more than gratefully appreciated as this is doing my head in!!!

Hi,
Thanks for the reply.
I am trying to reverse SAP tables. Initially the Reversal process stuck at Set MetaData step. I stopped the session and restarted it then Set MetaData completed successfully but Set FlexFields give the error.
Any idea?

Class Not found Exception for invoking BPEL process through the Java code

Hi.
The JDeveloper IDE raise the Exception From the invoking the BPEL process through the java code .Class Not Found Exception (Locator,ID.......).What is process of importing these classes from API.

In your code (.bpel file) import the library using the bpelx:exec tag. For example the adding the following entry in your .bpel file imports the com.oracle.bpel.client.util library.
<bpelx:exec import="com.oracle.bpel.client.util.*"/>

Class not found in import
