After installing and upgrading to the latest Servoy Version

Postby dlclark » Sat Jan 08, 2022 5:47 pm

Installed Servoy Version: 2021.12.0.3722 Windows 64 bit
Servoy cannot load tables from previous database connection defined in Resources. Running MYSQL 8,0 on Windows 10 also.

I have tried recreating the server: e.g. delete old spec and create a new one. Get the same error.

I have also tried creating a new solution , then defining a connection with a different name, same issue.

I have also tried uninstalling, reinstalling - cannot go back to previous version because workspace is now corrupted by updated version.

Any ideas?

Thanks,

Daryl

Also, I did uninstall the 2021.12.0.3722 Windows 64 bit ; then reinstall Servoy Version: 2021.9.0.3703

and created a new workspace; I can create database connections just fine in this version.

Have you checked the MySql driver is installed or up to date for the latest Servoy version?

do you get any exceptions in the various log files?
We test against mysql continuously so that should work fine.
What does the server editor say when you test a connection? is de driver correctly loaded?

I re-installed the latest Servoy upgrade and here is the error message I am getting:

An internal error occurred during: "Loading servers/tables needed by current solution".
Could not initialize class org.hibernate.cfg.Environment

Another bit of strangeness:

if I disable the server definition and delete it; then re-create the connection - the connection tests OK, but when I try to save it the screen appears to freeze a bit, then I get a error message indicating the server already exists.

This stime after I tried to recreate the server connection, I exited Servoy; upon restarting servoy developer, the connection is stored and since the form for testing the connection is still visible, the test connection is also successful, but still get the error message about hibernate.

that class should just be there
do you have full stacktrace/error information in the workspace and/or servoy log?

An internal error occurred during: "Loading servers/tables needed by current solution".
Could not initialize class org.hibernate.cfg.Environment

This is the error message I receive. I do not get a stack trace...

I do find a hibernate jar in the configuration directory under developer? Also in application_server/lib directory

are you sure you don't get any logging?
not in he servoy_log.txt file in the appliation_server dir
or in the workspace\.metadata\.log file?
