In compileng time this class not found import javax.media.jai.JA

Hi,
I�m download
jai_imageio-1_0_01-lib-windows-i586
jai_imageio-1_0_01-lib-windows-i586-jdk
jai_imageio-1_0_01-lib-windows-i586-jre
jdk-1_5_0_02-windows-i586-p
in compel time
import com.sun.media.jai.codec.*;
import javax.media.jai.JAI;
The complier gave me error class not found
How can i configured my system
I have Windows XP

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.

Javax.media.jai not in jmf.jar

Ive download JMF 2.1.1e from
http://java.sun.com/javase/technologies/desktop/media/jmf/2.1.1/download.html
and installed it. However it does not seem to contain the javax.media.jai or com.sun.media.jai packages as per the documentation :-
http://java.sun.com/products/java-media/jai/forDevelopers/jai-apidocs/index.html
I checked the contains of the jmf.tar and and the other jars that came with the download
eg the following can not be found
import javax.media.jai.widget.ScrollingImagePanel;
import javax.media.jai.NullOpImage;
import javax.media.jai.OpImage;
import com.sun.media.jai.codec.SeekableStream;
import com.sun.media.jai.codec.FileSeekableStream;
import com.sun.media.jai.codec.TIFFDecodeParam;
import com.sun.media.jai.codec.ImageDecoder;
import com.sun.media.jai.codec.ImageCodec;
So have I done something wrong, is this code no long in the jmf.jar, or is the documentation wrong ?

Thanks, that got me the jai_imageio.jar , however this jar does not contain the any of the following packages
import javax.media.jai.widget.ScrollingImagePanel;
import javax.media.jai.NullOpImage;
import javax.media.jai.OpImage;
import com.sun.media.jai.codec.SeekableStream;
import com.sun.media.jai.codec.FileSeekableStream;
import com.sun.media.jai.codec.TIFFDecodeParam;
import com.sun.media.jai.codec.ImageDecoder;
import com.sun.media.jai.codec.ImageCodec;
are they in another jar that I have not included, or do I need to get them from somewhere else?

Sure you can read and write at the same time. But normally you would be reading from one place and writing to another place.
I rather regret avoiding the OP's earlier post asking how to combine two classes. I looked at the two classes posted and realized the best thing to do was actually to break them into more classes. But I also realized it was going to be a big job explaining why and how, and I just don't have the patience for that sort of thing.
So now we have a Big Ball Of Tar™ and I feel partly responsible.

For weeks I have been viewing a doggy day care via their web cam. This weekend I upgraded to Lion and have been unable to view the center since. I get an error message for java webcam class not found. All of my software is up to date--suggestions?

For weeks I have been viewing a doggy day care center via their web cam. This weekend I upgraded to Lion and have been unable to view the center. I get an error message for Java plug-in 1.6.0_29 ....webcam class not found. Any suggestions on how to fix this?

Sorry, don't know what else to suggest unless there's a URL to the problem stream that someone here can try. Otherwise we can't test it to try and determine what might be wrong.
BTW, make sure they're testing it with a Mac, not with a Windows system. If they test only with Windows, what they say is or is not working doesn't mean much.

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,
Rahul Srivastava
[email protected]

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,

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,

Class not found because browsers need newer runtime environment - or this

For all who are experiencing the same problem!
Problem:
You're compiling your applets with a quiet modern compiler (i.e. Netbeans Version 3.5.1)
You are able to compile your applets without any problems but if you try your applets in "real life", the browsers can't interpret your applets [class not found]. (I tested Internet Explorer 6.0 and Netscape Navigator 4.7)
So you need a plugin for the new JAVA environment because the JAVA environment of the browser is older than that which the applet needs.
Well, you have the choice to demand to every user of your applet to download the new Java Runtime Environment, but then don't wonder why nobody visits your site!
But, don't worry: I figuered out another solution, that Netbeans (www.netbeans.org) allows to compile in different JAVA versions.
Solution:
What you have to do is:
- Install a previous version of JDK (i.e. JDK 1.3 - I would suggest, lower versions don't work with Netbeans 3.5.1 and JDK 1.3 is enough for IE 6.0 and NN 4.7, which I tested)
- Go into the "bin"-directory of Netbeans (i.e. c:/netbeans3.5.1/bin)
- Open the file "ide.cfg" (with notepad or any other texteditor)
- You see a line like: jdkhome "C:\java\j2sdk1.4.2" -J-Xmx96m -J-Xss1024k -J-Xms24m -J-Xverify:none
- Change the path to your other JDK you wish, like: jdkhome "C:\java\jdk1.3" -J-Xmx96m -J-Xss1024k -J-Xms24m -J-Xverify:none
- That's it, you can compile your applets in a previous version of JAVA so that "older" browser user don't have to install a plugin for the new JAVA environment.
Have fun!
If you have any questions I would be pleased to help you.
If this tip helped you already I would be pleased if you would send me a quick email with your experience.
My email: [email protected]

That's very good to know of course, but correct me if I am wrong with saying that Java development not
limited to NewBeans or any other IDE use.
If somebody wants to deploy the applets within browser built-in JVM (which is really outdated and just
Java 1.1.6 compliant) he or she should compile applet with Java 1.1.8 (still available from SunMicrosystems). Generated classes will be recognized by both Netscape and IE.

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 error on Firefox browser

Requirement:-
We have Apache server on the top of a tomcat container where we have deployed application Webnow. This application will provide SSO to another application Imagenow. The requirement is we have to authenticate and authorize a user based on the client certificate which will be installed on the client side browser.
Issue:-
We have achieved the requirement for the browser IE. But for browser Firefox ,we are getting an exception "Class not found". Basically an applet class from the jar is not getting loaded on the Firefox.
Further investigating on this we came to conclusion that Firefox is not able to read the SSL certificate.
In order to eliminate this, we have imported the client certificate in java console as well. After this step, we were not getting "ClassNotFoundException" in FF. But right now, user is getting prompted for certificate/keystore password each & every time while trying to login onto the application (both in IE & FF).
So, we are trying to find ways to remove class not found exception without importing client certificate to java console. Also , is there any way to eliminate the authentication pop up for keystore (though we might not go for this approach as it will be very difficult to manage Java console for end users). Need your urgent help on this issue.
Attaching stack trace of both the browser and screenshot of keystore authentication pop-up . FF_Issue_stacktrace.docx is one when we were getting "class not found exception" and IE_Stacktrace.docx is one for successful case.

We have a similar set up where we have a web app and an applet in a JSP page. You have to put your applet classes up above WEB-INF. So, if your structure for your webapp was:
tomcat/webapps/mywebapp
you'd want your classes under mywebapp instead of webapps/mywebapp/WEB-INF. In your case, if I read your package structure right, you'd want a Log directory under webapp that contains your LogApplet.class file.
I hope this works for you!

VideoTexture class not found

Hello,
I have been waiting for the videoTexture class for a long time and now it's been included with the new release of Air 17 sdk, but unfortunately I can't get it to work in my small test project. I read the release notes to find an answer for my issue with no luck at all, my problem is that Air 17 runtime can't find VideoTexture class and throws this error: VerifyError: Error #1014: Class flash.display3D.textures::VideoTexture could not be found.
It's really a simple project with 1 line only using Flasg Builder
package
     import flash.desktop.NativeApplication;
    import flash.display.Sprite;
    import flash.display3D.textures.VideoTexture;
    public class videoTextureTest extends Sprite
        public function videoTextureTest()
            trace("version="+NativeApplication.nativeApplication.runtimeVersion);
            var v:VideoTexture;
My working environment:
- iMac late 2013 with OSX 10.9 maverick 64-bit, 8GB RAM, 2.7 GHz Intel core i5, video card: Intel Iris Pro 1MB
- Flash Builder 4.6
- Desktop project
- Air 17.0.0.124 (flex developers) with Flex 4.6 merged
- swf-version=28 Compiler argument is set
- added <renderMode>direct</renderMode> in my xml discriptor
I have checked the runtime version with trace output, it's 17.0.0.124
I also ran a mobile version on my ipad mini 2 late 2013, same result: VideoTexture is no where to be found
Please help and thank you in advance

Class Not Found: com.bea.wlevs.adapters.jms.api.OutboundMessageConverter in Outbound JMS Converter

OEP 12.1.3
Following the instructions in 4 Adapters (12c Release 1 (12.1.3)) I have created a custom message converter bean for my Outbound JMS Adapter (I had to add the JAR file com.bea.wlevs.adapters.jms_12.1.3.0_0.jar from OEP_HOME\oep\modules to my project to make the code compile). However, upon deployment, I ran into a class not found exception:

I have tried adding the JAR file (com.bea.wlevs.adapters.jms_12.1.3.0_0.jar) to my deployment JAR. That did not make any difference.
Does anyone know why this class OutboundMessageConverter is not found - and more importantly: what I can do to make it available in the run time?
thanks.

To make a package available to your application at runtime for OEP, you will need to add it to the application's MANIFEST.MF file to the Import Package section (since the OEP server is OSGi-based). There's no need to supply a version number, you can just enter the package name (e.g.)
com.bea.wlevs.adapters.jms.api,

Oracle.forms.webutil.ole.OleFunctions class not found

Hi all,
I am getting oracle.forms.webutil.ole.OleFunctions class not found at design time in Forms Builder 10gR2 as well as at run time when working with webutil. Webutil is properly configured. I am using file uploading and downloading and it is working fine. but when I m working with CLIENT_OLE2, it is giving class not found exception. Can someone please help me to identify the problem.
Thanks in advance
Bilal

hi
Forms [32 Bit] Version 10.1.2.0.2 (Production in this version the webutil is already installed but u have to sign jars and there is also some modifications
in formsweb.cfg.
please check this.
How to get up and running with WebUtil 1.06 included with Oracle Developer Suite 10.1.2.0.2 on a win32 platform
Solution
Assuming a fresh "Complete" install of Oracle Developer Suite 10.1.2.0.2,
here are steps to get a small test form running, using WebUtil 1.06.
Note: [OraHome] is used as an alias for your real oDS ORACLE_HOME.
Feel free to copy this note to a text editor, and do a global find/replace on
[OraHome] with your actual value (no trailing slash). Then it is easy to
copy/paste actual commands to be executed from the note copy.
1) Download http://prdownloads.sourceforge.net/jacob-project/jacob_18.zip
and extract to a temporary staging area. Do not attempt to use 1.7 or 1.9.
2) Copy or move jacob.jar and jacob.dll
[JacobStage] is the folder where you extracted Jacob, and will end in ...\jacob_18
     cd [JacobStage]
     copy jacob.jar [OraHome]\forms\java\.
     copy jacob.dll [OraHome]\forms\webutil\.
The Jacob staging area is no longer needed, and may be deleted.
3) Sign frmwebutil.jar and jacob.jar
Open a DOS command prompt.
Add [OraHome]\jdk\bin to the PATH:
     set PATH=[OraHome]\jdk\bin;%PATH%
Sign the files, and check the output for success:
     [OraHome]\forms\webutil\sign_webutil [OraHome]\forms\java\frmwebutil.jar
     [OraHome]\forms\webutil\sign_webutil [OraHome]\forms\java\jacob.jar
4) If you already have a schema in your RDBMS which contains the WebUtil stored code,
you may skip this step. Otherwise,
Create a schema to hold the WebUtil stored code, and privileges needed to
connect and create a stored package. Schema name "WEBUTIL" is recommended
for no reason other than consistency over the user base.
Open [OraHome]\forms\create_webutil_db.sql in a text editor, and delete or comment
out the EXIT statement, to be able to see whether the objects were created witout
errors.
Start SQL*Plus as SYSTEM, and issue:
     CREATE USER webutil IDENTIFIED BY [password]
     DEFAULT TABLESPACE users
     TEMPORARY TABLESPACE temp;
     GRANT CONNECT, CREATE PROCEDURE, CREATE PUBLIC SYNONYM TO webutil;
     CONNECT webutil/[password]@[connectstring]
     @[OraHome]\forms\create_webutil_db.sql
     -- Inspect SQL*Plus output for errors, and then
     CREATE PUBLIC SYNONYM webutil_db FOR webutil.webutil_db;
Reconnect as SYSTEM, and issue:
     grant execute on webutil_db to public;
5) Modify [OraHome]\forms\server\default.env, and append [OraHome]\jdk\jre\lib\rt.jar
to the CLASSPATH entry.
6) Start the OC4J instance
7) Start Forms Builder and connect to a schema in the RDBMS used in step (4).
Open webutil.pll, do a "Compile ALL" (shift-Control-K), and generate to PLX (Control-T).
It is important to generate the PLX, to avoid the FRM-40039 discussed in
Note 303682.1
If the PLX is not generated, the Webutil.pll library would have to be attached with
full path information to all forms wishing to use WebUtil. This is NOT recommended.
8) Create a new FMB.
Open webutil.olb, and Subclass (not Copy) the Webutil object to the form.
There is no need to Subclass the WebutilConfig object.
Attach the Webutil.pll Library, and remove the path.
Add an ON-LOGON trigger with the code
         NULL;
to avoid having to connect to an RDBMS (optional).
Create a new button on a new canvas, with the code
         show_webutil_information (TRUE);
in a WHEN-BUTTON-PRESSED trigger.
Compile the FMB to FMX, after doing a Compile-All (Shift-Control-K).
9) Under Edit->Preferences->Runtime in Forms Builder, click on "Reset to Default" if
the "Application Server URL" is empty.
Then append "?config=webutil" at the end, so you end up with a URL of the form
      http://server:port/forms/frmservlet?config=webutil
10) Run your form.sarah

Class not found - from jsp sub-directories

Hello:
Main-Issue:
- I have some java-class files in the \<my-web-app>\web-inf\classes directory. These classes do not belong to any packages.
- I have some jsps in the \<my-web-app>\ directory and also in some sub-directories in the \<my-web-app>\ directory. Example: \<my-web-app>\test\index1.jsp.
- The jsps in the \<my-web-app>\ directory can invoke the classes in the \<my-web-app>\web-inf\classes directory with no issues. But, the jsps in the sub-directories CANNOT see the classes in the \<my-web-app>\web-inf\classes directory. I get a "class not found" error. (this is just in oc4j).
First of all, just a background to the issue:
- I am trying to port a web application from JRUN to OC4J.
- I want to do this with minimal changes to the existing code.
- The application has been running on JRUN for a while. I only see the above mentioned error (class not found) error when trying to run it on oc4j.
- As a test, I created my own test application to verify:
(-) I wrote a simple java class (test.class) with no package and placed it in the web-inf\classes directory
(-) I wrote a jsp file (index.jsp) to invoke test.class. I placed the jsp at the top-level directory of the web-app.
(-) I wrote another jsp file (index1.jsp) to invoke test.class as well. I placed that jsp file in a sub-directory in the top-level directory of the web-app.
(-) index.jsp worked without any problems. index1.jsp gave the "class not found" error.
(-) As another test, I then modified the class to be in a package (com.benny). I then changed the jsps to call "com.benny.test" rather than just "test". This time, both index.jsp and index1.jsp worked fine.
So, I guess my question is, do these classes have to be in a package? I am trying to avoid having to make a lot of changes to the app. If they do have to be in packages, then I have re-compile a lot of class files, add import statements to jsps, etc.
Any help/suggestion would be appreciated.
Thanks,
Benny

So, I guess my question is, do these classes have to be in a package?Answer: yes.
As of Java1.4, classes in the "unnamed" package were no longer accessible.
What version of java were you running with JRun?
What version are you running with OC4J?
Read all about it here:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4361575
If you have to repackage the classes, the IDE Eclipse has excellent support for refactoring, and wil let you put classes into packages with a minimum of fuss.

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

All,
I am quite new to RMI programming, although i am an experienced java programmer. I am facing a problem in starting the remote server program which i wrote for RMI. I am getting class not found exception for "stub" class eventhough the class is in the classpath.

... 12 morePLEASE ADVISE HOW TO RESOLVE THIS...
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{

public static void main(String args[]) {

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().

In compileng time this class not found import javax.media.jai.JA
