Ebase upgrade from 4.5.4 to 5.0.1 issue

[neilnewman]

I have carried out a TEST upgrade from Ebase 4.5.4 to Ebase 5.0.1, I get the following error messages in my catalina.log file:

I understand that this may be due to it not liking the version of Java installed.
I have version 8.72 both 64 & 32 bit installed (testing upgrade out on my 32/64bit Windows 7 PC)

Any pointers as to what I have wrong please?

Yes you're right, it is the Java version, this must be a minimum of 1.7.

[neilnewman]

Hi Jon,
I have Java 1.8 installed, so this is greater than 1.7, does it not work with anything beyond 1.7?

Many thanks
Neil

[Jon]

Yes 1.8 is fine. Are you sure you're actually using this level?

[neilnewman]

Hi Jon,
I found the issue, even though the machine had Java 8 installed the script "start_ebase_server.bat" referred to
set JRE_HOME=%~dsp0..\jre
which held a copy of java 6.
System is currently upgrading to version 5.

Many thanks for your help

I had a very similar problem. Ultimately I was upgrading from v4.5.1 on our test server and everything was going great until i completed the designer upgrades. The designers wouldn't load, on investigation I received the error:

Code: Select all

Exception in thread “main” java.lang.UnsupportedClassVersionError: a (Unsupported major.minor version 51.0)

I then removed the jre folder from the client directory and copied in a jre folder from a 1.8.65 installation I had to hand. This brought the designers to life.

Hope it helps if someone else encounters the same sort of thing.
