[jdom-interest] serialVersionUID for JDOM classes

[Andres March]

Ignore my last post.  I was double checking all my work and I don't know what changed but using jdom.jar is working fine.  I still and unable to get the compiler in JBuilder to create the same class version ID as the command line even though they are using the same SDK.  I know it is related to the compiler options but the only one that affected the ouput was includeDebugInfo.  Unfortunately that just moved the error from Document to ContentList.  I have run out of time, so I will be using the binary from the distribution.  Hopefully, I will never need to mae any customizations.  Thanks again for your help.

Hi Andres,

are you 100% sure that the server and all clients use the same version of
JDOM classes? Do you have cached classes somewhere (e.g. an outdated Java
Web Start Cache, a browser, ...)? The exception quite clearly says that the
class versions are not the same and this is most probably not a problem of
the virtual machine version but rather exactly what it says (own
time-consuming experience). Application servers sometimes have strange
manners regarding where they hide the libraries you feed them... You can try
serialver to compare the serialVersionUID of your libraries on client and
server. 

I agree that once there is a stable set of classes it would probably be a
good idea to add a serialVersionUID to prevent this kind of problems.

Best Regards,

Daniel
