Re: Classes generated by eclipse vs javac have different serialVersionUID

I'm using eclipse 3.2 for development and have configured my project to
use JDK 1.5.0_07 with Compiler compliance level 1.3 (using default
compliance settings) and selected all "Classfile Generation" options
except "Inline finally blocks." The problem I'm having is that the
class files that are generated by eclipse are not the same as those
generated by javac (also using JDK 1.5.0_07), which is used in a make
script. javac is invoked like so:

javac -source 1.3 -g -d classes -nowarn -deprecation -classpath
<classpath> ...

The different class files cause a problem because I have serialized
some objects already with the javac classes so when I try to
deserialize them with the eclipse classes, I get the
InvalidClassException. When I run serialver on the offending class
file, I get two different values for the class file generated with
javac and the one generated using eclipse.

Has anyone ever had this or some similar problem? How do I correct this
(besides not using the eclipse class files)? I've spent many hours
scouring the web to find a solution, but have had no success. Any help
would be really appreciated!

    Isn't it possible to directly specify the serialversionUID by declaring
the appropriate static field?
