Dear Support

We evaluated the OMR reading from an image from the command prompt and it worked fine.
We are trying to create an Applet for this and we are getting the below exception.

class com.aspose.omr.internal.aj: Unable to create an element —> java.lang.Cla
ssNotFoundException: com.aspose.omr.ChoiceBoxElement

Hi,


Thank you for contacting Aspose support.

We have evaluated your presented scenario by creating a simple applet application in Eclipse IDE while using the latest version of Aspose.OMR for Java 2.0.0. Unfortunately, we are unable to replicate the said exception on our end. In order to further investigate the matter, we would request you to please archive your workspace (sample application) and attach the zip file here along with your environment details such as follow.

  • Operating system version
  • Operating system architecture (32bit/64bit)
  • JDK type
  • JDK version

Above code is working Ecllipse. same code not working on terminal.

Please send sample code for executing ocr with using any IDE.

Hi Ramesh,

Please find the detailed articles and source code snippets on the following link.

Regarding the original problem, as you have narrated that the Applet type project works perfectly in the Eclipse environment that means the problem isn’t on the part of Aspose.OCR for Java API. You should confirm the arguments that you are passing from the terminal to load the applet with applet viewer. Moreover, you require the aspose-omr-x.x-jdkxx.jar for this operation not aspose.ocr.jar that you have included in your attached archive.

Hi Aspose Team,


in the above attached code aspose.jar is OMR jar file. i am passing exact path to to the OMRTemplate.Load(filepath). but it gives Exception as Unknow source. please help to me.

Hi Ramesh,


ClassNotFoundException occurs when Java Virtual Machine tries to load a particular class and doesn’t find it in the classpath. If you can compile the code without receiving any errors during the compilation time then the com.aspose.omr package is in place as expected. Moreover, you are able to run the applet through IDE without any issue so the problem does not seem to be related to the Aspose.OMR for Java API. I am mentioning these facts so that you could check other possibilities (configurations, command line arguments) as well while troubleshooting this problem on your side.

Please consider the following.

  • If you have obtained the ocr.class by compiling the ocr.java from an IDE such as Eclipse then the code directive inside the index.html should contain the package name preceding the class name code = “[packagename]/ocr.class”,
  • Try loading the applet through terminal as appletviewer index.html or/and directly into the browser.

If you still find problems then please provide us your environment details such as follow for further investigation.

  • Operating system version
  • Operating system architecture
  • JDK type
  • JDK version

Dear Support Team

The Class not found exception is not occurring at the omrTemplate class. That is occurring at internal.aj class which is called from the omrTemplate and ak like this… .The error we are getting is no class Choiceboxelement. or no class gridelement which is placed in the template.amr file.


But when we remove the elements from the template.amr there is no error and eof reached without throwing any exception.
