I created a web app which use mysql. I used spring for the persistence.
Every thing worked on my local tomcat server.
I upload it into cloudfoundary, I follow the instuction and I create a mysql service and I use it
as a service for my web-app.
I try to run the app and I got the following exceptions:

If the problem is still there: there are 2 ways to configure a connection to CF services.
1) Taking the advantage of "auto-reconfigure". For any Java app, if it is using Spring framework, the doc here specifically described the details: http://docs.cloudfoundry.com/frameworks/java/spring/spring.html
2) For Java apps, other than Spring apps, the details of connection to the CF provisioned services like hostname or password needs to be taken care explicitly. These can be retrieved by an environment variable named "VCAP_SERVICES". Simply this code snippet can achieve that:
System.getenv("VCAP_SERVICES")
After that set the properties to the connection configuration.

Analytics is already enabled in the slave region. Also, we are able to telnet on port 7712 to the analytics service in the master region.
Why is the "java.net.SocketTimeoutException: Read timed out" occurring?
There are a lot of points that you should check.
Domain resolution on the slave region.
Check the connection from the slave to the master , firewall rules , etc.
Check the certificate on both sides and that it match with the domain name.
Use openssl s_client -connect wso2apim-analytics-service.domain.com:7712
Good luck.
Once the debug logs are enabled for below class, when graphs are selected for analytics, it will log the Siddhi queries it sends to the analytics server.
This would help us to capture exact queries publisher portal sends to the analytics server and try to identify any culprit points available.
Shutdown the server.
Add the following property to /repository/conf/log4j.properties
log4j.logger.org.wso2.carbon.apimgt.impl.utils.APIUtil=DEBUG
Restart the server
Please refer to [1] for more details on logging.

can you please advise?
Thanks.
Can you share the WSO2 SP version you were using when you got this exception?
Also please check whether the AUTO_SERVER=TRUE
config is avaiable in the jdbc url of WSO2_METRICS_DB datasource configuration, which can be found in
{WSO2_SP_HOME}/conf/worker/deployment.yaml
eg :
jdbcUrl: 'jdbc:h2:${sys:carbon.home}/wso2/dashboard/database/metrics;AUTO_SERVER=TRUE'
I configured all datasource in mysql, and i can running all SP componnent.
the issue is related to H2 datasase, that not allowed to share connection with default configuration.
i will check default H2 connection parametrs, and test again.

I don`t modify any code and I could get the successfully test results on the API browser explorer. Has anyone met this kind of issue before?Could you please give me any suggestion?
java.net.SocketTimeoutException means the connection timed out before a response was received from the remote host. This is almost always caused by local network issues, or proxy or firewall configurations.
I solved this by setting proxy mode to global mode
it's a very basic example.
I wanted to load the web application using jetty like below.
public static void main(String[] args) throws Exception {
Server server = new Server(8085);
WebAppContext webapp = new WebAppContext( "D:/workspace/camel/TestWithGradle/src/main/java/sample.war" , "sample");
webapp.setExtractWAR(true);
webapp.setParentLoaderPriority(true);
server.setHandler(webapp);
server.start();
server.join();
}
And the war is https://github.com/heroku/heroku-deploy/blob/master/spec/resources/sample-war.war
it's very simple war that uses jsp files and java servlet.
But, I run this application, the console gave the exception..

Please, help me with the elaborate explanation. thanks for reading and your time.
You have an XML with a bad DTD or namespace declaration.
The startup is attempting to fetch some sort of resource from a remote URL that would be used in validating the XML.
This will not happen with a normal jetty distribution, or the normal jetty jar artifacts.
Start with making sure you are using the official jetty jars, don't repackage them, don't uberjar them, don't one-jar them, leave them alone (for now).
Then make sure you have no typos in your various XML files. Especially in your war file, and all of the contents of the WEB-INF/lib/*.jar files. There is likely a small typo or reference that is incorrect enough that Jetty can't shortcut that remote resource request with the validation resources that comes with the jetty jars.
