With Windows Server 2003 past end of life, we upgraded to 2012R2. Our stack was then:
OS Windows Server 2012 R2
Tomcat Apache Tomcat/7.0.69
All seemed in order, but we found that the Discrepancy Note popup was always empty - it was no longer possible to create a new DN.
We tried upgrading OpenClinica to 3.11. There was a script to run to remove some duplicate rows, but seemingly no other database changes to make. The new war file deployed fine in Tomcat, and I edited the new datainfo.properties file as required (the structure had changed a bit since 3.0.4 so it was not a simple copy).
No luck though. I can get to the login page, and an invalid username/password is rejected. If I put in a valid username and password though I get a 500 server error page. There is no stack trace in the log.
Any ideas what the problem might be? Where else should I look for some clues? Is that upgrade path (3.0.4 to 3.11) even supported?
Many thanks in advance.
