Question

I try to connect to the database, which is on remote server. I use jdk 1.7.0_60, Hibernate-release-4.3.5 final. In project are included following jars:

antlr-2.7.7.jar;
dom4j-1.6.1.jar,

hibernate-commons-annotations-4.04.Final.jar,
hibernate-core-4.3.5.Final.jar, hibernate-entitymanager-4.3.5.Final.jar, javassist-3.18.1-GA.jar, jboss-logging-3.1.3.GA.jar, jboss-logging-annotations-1.2.0.Beta1.jar,jboss-transaction-api_1.2_spec-1.0.0.Final.jar, mysql-connector-java-5.1.30-bin.jar.

the exception is following:

How can I solve this problem?

Answer 1

The problem is with mysql-connector-java-5.1.30-bin.jar. Replace it with mysql-connector-java-5.0.8-bin.jar . It will solve that exception .

Answer 2

Please make sure that the database server is up and running.Looks like the server is not responding, as there are no packets received and timeout is happening.
