Fast Object Database for Java - with JPA/JDO support

SSL cannot connect from client StackOverflow error

#1

Hello,

i am trying to set up the SSL for connections to objectDB server.
I cannot connect the Client, when SSL is enabled.
I can connect from Explorer, when "Use SSL" is checked, isn't there some option, which I missed on java client side?
I read https://www.objectdb.com/java/jpa/setting/ssl and didn't saw any additional option needed.

It fails on method PersistanceManagerFactory.getPersistenceManager()

On server it keeps writing SSL Error: Unsupported or unrecognized SSL message until the StackOverflowError is printed.

When "Use SSL" is enabled, the Explorer uses a connection url that starts with objectdbs:// instead of objectdb://. This seems to be the only difference on the client side.

Thank you,

appreciate quick reply.

Indeed, that was the difference, now it is working correctly.
I suppose, that it should be mentioned in the SSL howto https://www.objectdb.com/java/jpa/setting/ssl

Thank you again for this report. The relevant manual page was updated now.
