Hi Chengfang,
What version of Tomcat are you running? And what version of the TDS do
you have deployed?
Actually, did you have an earlier thredds.war installed and then install
a new thredds.war over the top of that? And how did you do this undeploy
and deploy? Are you using the Tomcat Admin interface to undeploy and deploy?
The root cause of java.lang.IncompatibleClassChangeError makes me think
that there are two versions of the same .class file(s) somewhere in your
TDS/Tomcat. Or that the deploy of the new thredds.war didn't go as it
should.
I would suggest you make sure you fully undeploy the TDS first. By which
I mean, once you undeploy, make sure the ${tomcat_home}/webapps
directory does not contain either a thredds directory or a thredds.war
file. (It seems like the various ways to undeploy in Tomcat don't always
clean this up and sometimes the deploy trips over this stuff.) Then
redeploy from a clean war file. There is a download link to the newest
TDS war file at http://www.unidata.ucar.edu/projects/THREDDS/tech/#TDS.
