Hello Professor,

In my WEB-INF folder , somehow there are duplicate xmls for csns-data, csns-servlet, csns-security and csns-email.

they are named as ${app-name}-data.xml , ${app-name}-servlet.xml and so on ....

Any changes made to spring servlet or spring security or spring data are getting updated in these duplicate files.

Do i delete these files or rename them ? i am not sure why this happened...although if i manually make changes to csns xmls the project runs fine...

Thank you.

You can delete those files, those are not required. They might have been created in a state when either your build.properties or ur conf related files were inconsistent.To be sure you can even delete the csns-*.xml files and rebuild  them, so that they are regenerated afresh.
