Object Instantiation Exception Class Not Found

Hope this tutorial helps you when you find that the object creation exception class was not found.

object instantiation exception class not found

I found a workaround for my specific error, which is to add your current C: ColdFusion10 cfusion wwwroot WEB-INF classes path to ColdFusion in the classpath parameter. However, I am not optimistic as to why this is necessary. Details below:

I took a legacy from Music [don’t know who wrote it or where it came from] Java Lecture in ColdFusion To 9 Help, looked at the files in my mailbox and analyzed. When I updated ColdFusion to 10 it stopped working. Here’s a quick example:


Differences between objects. An exception was thrown while instantiating a Java object. The class cannot be a user interface or an abstract class. Error: javax / mail / store.

However, when I add something to the test page, CF10 can find and fix javax.mail.Store:


javax.mail.Registered Today’s mail.jar files were compiled with ColdFusion and are located in C: ColdFusion9 lib and C: ColdFusion10 cfusion lib in CF9 or CF10.

object instantiation exception class not found

MboxReader.class is the last C: ColdFusion9 wwwroot WEB-INF classes its util and (CF9 c: coldfusion10 cfusion wwwroot web-inf classes its util or CF10).

If I manually add C: ColdFusion10 cfusion wwwroot WEB-INF classes to the ColdFusion classpath in all cf admins it works.

I hardly know why ColdFusion can find variety, but the MboxReader class definitely cannot add the classpath. Accordingly, on the way to about Java and J2EE , ColdFusion should load the classes in WEB-INF / classes.


When I use Main as a method, I find that Method not found

* SubkeyGrants access to the reader via COM port 1 and requests to view tags.

// To connect to a network drive, use:

// Have the reader read the labels and print them

The following information is for web developers for debugging purposes.
An error occurred during processing despite the request
< table readabilitydatatable= " 0" >

Either there are Neo methods with the specified detection methods and argument types, or the main method is overloaded with parameters Argument sorts that ColdFusion cannot reliably decode. Found 0 Coldfusion methods matching all of the provided arguments. If it’s a specific Java object and you’ve checked which method is present, use the specific javacast function to reduce ambiguity.

  • Enable trusted information exclusion to provide additional information about error source. In the admin panel, click Debugging and Logging > Debugging Options, enter and select the Above option For more information on the exception.
  • Check, I would say, the ColdFusion documentation to make sure your company is using the correct syntax.
  • Search the entire knowledge base for a selection. related to your problem.
