Crystal Report Unknown DTO

I have been using a previous version of report server which is working correctly, with the exception of the crytsal report in the dashboard. I understand this has been fixed with the latest release and I have installed the latest version under webapps/reportserver2 and the database called reportserver2. When trying to create a report for Crystal Reports I get the following:

Re: Crystal Report Unknown DTO

Hi Guys,

Quite strange, but I have since restarted tomcat and now the crystal report is working as expected.

Re: Crystal Report Unknown DTO

Self healing software

Joke aside, could it be that you did not have the Crystal libs properly set up the first time you started the server? A second possibility
for this kind of error is a browser cache that still holds data for an old version of ReportServer. So whenever you switch versions
it is recommended to clear the cache.

Re: Crystal Report Unknown DTO

Thanks for responding Arno.
Yes I believe it is one of the two issues mentioned. To be honest after the restart of Tomcat I did do a CTRL + F5, so certainly it could of been a cache issue, but I suspect a mixture of the two. It's working great now anyway and crystal is working with the dashboard gadget.
