Please help to get it resolved.

This looks like network issue, check if you are able to ping, telnet the host as well as the jdbc port and service-id is correct

I know this question is 5yo but I've encountered a very similar problem, although I've not been using any proxy and running both the app and DB on local machine. By the way, it seems that your app was able to access the DB and connect to it. The DB just aborted the connection because it received invalid packet.
In my case the problem was with the data source I was using: org.springframework.jdbc.datasource.DriverManagerDataSource from the org.springframework:spring-jdbc:4.3.9.RELEASE. I don't know why this data source kept failing, but using org.apache.commons.dbcp.BasicDataSource from the commons-dbcp:commons-dbcp:1.4 resolved the issue. Using ComboPooledDataSource from c3p0 works as well.

GAE and Spring Social

I'm trying to connect my application to Google+.
I have:
Spring Social 1.1.4.RELEASE
Google App Engine 1.9.38 (for the frontend layer)
Tomcat v7.0 (for the backend layer)
When I try to authorize my google gmail credentials to access to the applcation,
Spring launchs this error:
HTTP ERROR 500
Problem accessing /connect/google. Reason:
java.net.ProxySelector is a restricted class. Please see the Google App Engine developer's guide for more details.

I also see that the problem should be in this class: HttpClientBuilder.class.
In this part of code, we can see:
if (hostnameVerifier == null) {
hostnameVerifier = SSLConnectionSocketFactory.BROWSER_COMPATIBLE_HOSTNAME_VERIFIER;
}
if (sslcontext != null) {
sslSocketFactory = new SSLConnectionSocketFactory(
sslcontext, supportedProtocols, supportedCipherSuites, hostnameVerifier);
} else {
if (systemProperties) {
sslSocketFactory = new SSLConnectionSocketFactory(
(SSLSocketFactory) SSLSocketFactory.getDefault(),
supportedProtocols, supportedCipherSuites, hostnameVerifier);
} else {
sslSocketFactory = new SSLConnectionSocketFactory(
SSLContexts.createDefault(),
hostnameVerifier);
}
}
The problem is that i should set systemProperties as false
Is it possible to do this without override the class?

Please help me through this

The error message appears to be from Google, based upon the java library. I suggest consulting with Google Support to gain further understanding of the error message.
As a further note, the Java library is an open-source and unofficial library created by the Recurly user base. You may want to request further follow-up for Java support at https://github.com/killbilling/recurly-java-library `

Intermittently getting exception "org.hibernate.exception.JDBCConnectionException: Could not open connection" on Google app engine

I am using Google App engine, CloudSQL and Hibernate in my project. For last few days I am getting an exception "org.hibernate.exception.JDBCConnectionException: Could not open connection" for some time and it goes away after some time.
Error log shows the error happens for roughly 50% of my API calls
Have checked the hibernate configuration and seems to be right
This has become a major issue now. Any help is appreciated.

It seems to me, you do not ALWAYS close/disconnect Hiberante's Session. To make sure it always happen, no matter what exception are thrown, you could execute your code in a try/finally block, otherwise the connection is not returned to the JDBC pool (where you have a bounded number of connections).
In case you use the JPA API, you should call the EntityManager.close() method.

My issue is solved after I started using
ServiceRegistryBuilder builder = new ServiceRegistryBuilder().applySettings(configuration.getProperties());
SessionFactory sessionFactory = configuration.buildSessionFactory(builder.buildServiceRegistry());
Previously I was using the deprecated method(below) which seemed to work for limited time be then started giving errors for around 50% calls.
SessionFactory sessionFactory = configuration.buildSessionFactory();
I am using hibernate 4.2 so have not used StandardServiceRegistryBuilder

GeoServer database failure while creating a 'CoordinateReferenceSystem' object for code "EPSG:4326"

I received this error at my GeoServer 4.2.
and tried to reinstall it.

you can solve this problem by this url
http://docs.geoserver.org/stable/en/user/advanced/crshandling/manualepsg.html
just remove the temp folder for geoserver

Remove the cached copy of the EPSG database, so that can be recreated. On Linux, the command is:
rm -rf /tmp/Geotools/Databases/HSQL
Restart GeoServer.
