Subject Re: Error integrity constraint violation
Date Tue, 19 Feb 2019 04:58:49 GMT
Hello, Wright:

Thank you for your answer.

I had not edited my own connector's build.xml, which I had copied from
WebCrawler Connector.
After I edited the build.xml for changing my class name, MCF runs fine.

Again, I appreciate for your help.

Sincerely,
Kaya
