Building error in development environment

[w12315007]

Hi,
I downloaded the portable development environment( ova ), and imported it into virtualbox. I could start linux and
open the eclipse. But as starting the tomcat eclipse console shows errors : "Name [openkmDS] is not bound in this context.Unable to find [openkmDS]" (details in the attachment). At the same time, I can open the login
page in the browser(http://localhost:8080), but could not login the system after inputting the user name and password.
I am a java newer, so can anyone help me for this question? Thanks in advance.

Check if into tomcat-8.5.24/conf/server.xml is defined the openkmDS.
Did you created a new server or are using what it comes with eclipse, did you modified something in the server configuration ?
