Re: Cannot serialize session attribute

[Socheat KHAUV]

Did your class implement to the serialiable interface as well ?
and did you generate the serialID ?

Subject: Cannot serialize session attribute

Hello iBatis people:

I am using Eclipse Version: 3.0.0 (Build id: 200406251208) and Tomcat 5.0.19.

I edit a java file (in the Eclipse), and click on the 'Save' button. The 'Reloading" starts as expected.   However, very often (but not all the time), I get the following error messages although these errors don't seem to have any impact on the compiling process.  I have highlighted (in red) what I thought are key messages.

        --------------------here are some sections of the error message--------------------------------

The 'myfileBean' is the name of one of my JAVA files.   The strange thing is that when this error is generated, I am usually working with another JAVA file.

Any ideas?

Thanks.
