I am trying to upload a photo using UploadBean. But I am getting error.







Here is my exception :


HTTP Status 500 -

I think you would have to replace the class name with just UploadBean.

As you have already imported using:

1. <%@ page language="java" import="javazoom.upload.*,java.util.*" %>

<%@ page language="java" import="javazoom.upload.*,java.util.*" %>

I have done that already. Same error persists.....

Ok, now I have resolved that the problem is only for Eclipse.

In Windows , I tried to run the same project in NetBeans IDE, it ran correctly.

But, back in Linux when I try to run , the same problem persists.

I suspect the problem is of adding external jars of uploadbean , though I have added DB2 jar file correctly and it's working fine.

Here I am giving the screenshots :

/ 2nd Screenshot

please help....

Sounds like you simply have CLASSPATH issues, make sure the required libraries are in your CLASSPATH. In Eclipse this is under the Run Configuration area.

The problem was solved. I just had to extract the jar files and copy the extracted folders to build/classes/ folder.

Thank you guys for your support......
