I have recently installed Myeclipse 8.5 (trial).

I am trying to connect to Mysql server(5.1) using Mysql connector(mysql-connector-java-5.1.12-bin) in my newly installed MyEclipse8.5 neither inbuilt derby server is connecting.
and additional to it i am unalbe to connect to derby server as well.
previously i was using Myeclipse 6.0 on same PC and was able to connect to both of server.

following is the error displayed:

“error while performing databse login with the mysql driver:communications link faliour .the last packer sent successfully to the server was0 miliseconds ago.
the driver has not received any packer from server“.

Kindly note the i am able to connect to Mysql Server using same driver in myeclipse 6.0

Kindly help me Sir.Thanking you

[support-shalini]

viren1984,

installed MyEclipse8.5 neither inbuilt derby server is connecting.
and additional to it i am unalbe to connect to derby server as well.

In either cases, please make sure that the mysql server/service and myeclipse derby are started.
The “Communications link failure ” and “Connection refused: connect. ” are caused when you try to access the data base when servers are not running.
Let me know if that helps.
