I get the following error message when trying to connect a web app running on EAP6 to MySQL in OpenShift.
javax.persistence.PersistenceException: org.hibernate.exception.JDBCConnectionException: Communications link failure
How do I fix this?
The same issue was discussed at https://community.jboss.org/thread/202318.
The solution is to append "?autoReconnect=true" to the connection URL. You do this in the standalone.xml file, found in the .openshift/config folder in your OpenShift Maven project.
EDIT
This is actually a known bug: https://community.jboss.org/thread/177144. Validating the connection can be used as a workaround.

I was struggling with my webapp (wsesupport) on Openshift with Wildfly 10 and MySQL 5.5. Each time I published from within eclipse, (In server view, right click on wsesupport at Openshift) my project was not deployed, and in the log files I could find the error message:
2016-03-10 17:32:56,740 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("deploy") failed - address: ([("deployment" => "ROOT.war")]) - failure description: {"WFLYCTL0180: Services with missing/unavailable dependencies" => [
"jboss.persistenceunit.\"ROOT.war#wsesupport\".__FIRST__PHASE__ is missing [jboss.naming.context.java.wsesupport]",
"jboss.persistenceunit.\"ROOT.war#wsesupport\" is missing [jboss.naming.context.java.wsesupport]"
I re-added many times my datasource online through the admin console of myapp. I did this through the rhc port-forward wsesupport command and then in the browser localhost:9990. I noticed after the publishing, the entry I made in the Non XA datasources always disapeared.
In Mac, i searched for Resources (cmd-shift-r) and searched for standalone.xml. I did this because in the past I remembered I could deploy the standalone.xml with my web app and the config would be added to the default Wildlfy config (or something like that). So i thought to give it a try, maybe I was unaware of such a file in the project...
Surprisingly, it found it in an hidden openshift folder. If you are using eclipse (for sure) and the openshift plugin it will find it right away. There I copied the current MySqlDS configuration like this:
<datasource jndi-name="java:/wsesupport" enabled="true"
use-java-context="true" pool-name="wsesupport" use-ccm="true">
<connection-url>jdbc:mysql://${env.OPENSHIFT_MYSQL_DB_HOST}:${env.OPENSHIFT_MYSQL_DB_PORT}/wsesupport
</connection-url>
<driver>mysql</driver>
<security>
<user-name>${env.OPENSHIFT_MYSQL_DB_USERNAME}</user-name>
<password>${env.OPENSHIFT_MYSQL_DB_PASSWORD}</password>
</security>
<validation>
<check-valid-connection-sql>SELECT 1</check-valid-connection-sql>
<background-validation>true</background-validation>
<background-validation-millis>60000</background-validation-millis>
<!--<validate-on-match>true</validate-on-match> -->
</validation>
<pool>
<flush-strategy>IdleConnections</flush-strategy>
</pool>
</datasource>
I then published my project again and it was working!
PS do not delete the ExampleDS! WildFly apparently needs it!
PS2 do not format the standalone.xml within Eclipse! When i did it, I received this weird error: java.lang.IllegalStateException: You have to start the service first!
Good luck!
I am getting following error when I try to connect yahoo
pop3s. plus.mail.pop.yahoo.com:995
error while connecting to pop3 mail server javax.mail.MessagingException: Connect failed;
nested exception is:
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
I have already tried adding the certificate into JAVA_Home/jre/lib/security. Also when I am trying to use the same code directly using the Java/javac Cmd it works. But from tomcat it does not work.
Also: the code which I am using that was working since last two years on same server. Recently we have migrated from dedicated server to cloud based server. Backspace is the vendor where we have deployed the code.
Thanks in advance!

Most probably cause os this is that the system is unable to locate a valid certificate because in your migration something related to the keystore was not properly set.
Review your configuration file $CATALINA_BASE/conf/server.xml and look if the path to the correct keystore is set under Connector tag. If you are using JSSL look for this in that file
<-- Define a SSL Coyote HTTP/1.1 Connector on port 8443 -->
<Connector
port="8443" maxThreads="200"
scheme="https" secure="true" SSLEnabled="true"
keystoreFile="${user.home}/.keystore" keystorePass="changeit"
clientAuth="false" sslProtocol="TLS"/>
Your keystoreFile has to be set to the correct path in order your application can validate amd resolve a certificacion path in a request (the keystorepass have to be correct too, indeed).
If you have another configuration (APR or something) look at the documentation about in http://tomcat.apache.org/tomcat-6.0-doc/ssl-howto.html
Hope this help,
Cheers!!
I observe the following stack trace when I try to start my jboss server (from both eclipse IDE and the standalone.sh from my unix terminal). Could anybody please tell why?:

This means that there is some problem with your Standalone.xml. Take a fresh one, it should work.
Here are the relevant lines
JBAS014676: Failed to parse configuration
Caused by: com.ctc.wstx.exc.WstxEOFException: Unexpected EOF in prolog
Looks like you're missing a configuration file (or more likely it's empty).
I just came across the same problem and found out that standalone.xml was empty.
I don't know what could have caused this though... U can find back up of ur standalone.xml in ${AS7_installation}/standalone/configuration/standalone_xml_history
I get following error using hibernate:
Exception in thread "main" javax.ejb.EJBException: org.hibernate.exception.JDBCConnectionException: Cannot open connection
...
...
Caused by: java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/db
The problem is similar to: other question but I think my url is right!
Solution
i found the solution searching here on stackoferflow :)
I needed to place my mysql-connector jar file into jboss/server/default/lib.
Although I dont understand it since i added this jar file as a dependency and it was placed in the lib folder on deployment.
I have a groovy application running locally on my desktop.
Apparently it runs error free. At least all unit tests I wrote are fulfilled.
I want to deploy the application using a war file. For this I use the command
grails war
in the home directory of the application. When doing this I am getting the following exception:
Error executing script War: java.lang.NullPointerException

Any hint why?
Thanks a lot in advance
I think you'll have to find the source of Gant.groovy and see what it's doing on that line. Apparently there is some problem caused by your project's specific configuration (since such a show-stopper bug would have been caught if it always occurred), but the error message does not contain much information.
Alternatively, you could try upgrading Grails to the latest version 1.1.1 if you haven't already.
