Re: Help for servlet!

Hi,

to see the problem you should print the exception, not only its
detail message. Replace

out.write("Error " + e.getMessage());

by

out.write("Error " + e );

I guess you will then see something like

java.lang.ClassDefNotFoundException: org.apache.xindice.client.xmldb.DatabaseImpl

It is a common mistake in Java to output only
ex.getMessage(), but this is only the "detail
message".

Tell us which exception you got.

Regards
Georg
