I am using HikariCP in a spring project.
Right now, I defined a connection like this
<bean id="hikariConfigLegacyReasonCode" class="com.zaxxer.hikari.HikariConfig">
<property name="poolName" value="HikariCPReasonCodePool" />
<property name="connectionTestQuery" value="SELECT 1" />
<property name="dataSourceClassName" value="com.mysql.jdbc.jdbc2.optional.MysqlDataSource"/>
<property name="registerMbeans" value="true"/>
<property name="maximumPoolSize" value="15"/>
<property name="idleTimeout" value="60000"/>
<property name="connectionTimeout" value="5000" ></property>
<property name="dataSourceProperties">
<props>
<prop key="url">jdbc:mysql://${LegacyReasonCodeIp}</prop>
<prop key="user">${LegacyReasonCodeUsername}</prop>
<prop key="password">${LegacyReasonCodePassword}</prop>
<prop key="cachePrepStmts" >true</prop>
<prop key="prepStmtCacheSize" >250</prop>
<prop key="prepStmtCacheSqlLimit" >2048</prop>
<prop key="useServerPrepStmts" >true</prop>
</props>
</property>
Here, Server name , username and password will be loaded from a property file. Is there any way to store the DB password in the property file in encrypted manner ?
Try the jasypt project. It includes a number of integrations for Spring, including implementations of:

I am investigating the use of a JTA transaction manager with Spring Data JPA. I have successfully configured Atomikos and Bitronix and am trying to configure JBossTS (Arjuna/Narayana).

There does not seem to be any documentation on whether JNDI is mandatory to run JBossTS and if yes, how it can be configured in a standalone application that does not use a JavaEE container.
A sample application is available on Github in case the full configuration and source code is required. The problem can be seen by running Maven tests as mvn test -D"spring.profiles.active=jbossts".

I am unable to read data from DB.I need to fetch data from Oracle using hibernate corresponding to the data from the request. I configured like this but getting error above shown
Can someone please help me on this?
I have pasted above the code snippet from configuration file.
If your hibernate configuration file is named Hiber.hib.xml then definitely this won't work. Rename it to hibernate.cfg.xml.
Furthermore I see you are intermixing Annotation based Entity mapping and *.hbm.xml based Entity mapping. Don't do this and try to use one method.
I was following http://terasolunaorg.github.io/guideline/1.0.x/en/ArchitectureInDetail/Pagination.html to implement Pagination support for my MVC application
When I try to start the JBoss Server,
nested exception is org.springframework.data.repository.query.QueryCreationException: Could not create query for public abstract java.util.List com.repo.MyRepository.searchEntitySC(java.lang.String,java.lang.String,java.lang.String,java.lang.String,java.util.Date,java.lang.String,java.util.Date,java.lang.String,java.lang.String,java.lang.String,org.springframework.data.domain.Pageable)!
Reason: Your persistence provider does not support extracting the JPQL query from a named query thus you can't use Pageable inside your query method. Make sure you have a JpaDialect configured at your EntityManagerFactoryBean as this affects discovering the concrete persistence provider.
I tried to follow, http://forum.spring.io/forum/spring-projects/data/99613-you-cannot-use-pageable-as-method-parameter-if-your-persistence-provider-cannot-extra
But I don't know how to apply the suggested configuration for entityManagerFactory
as my jpa-config.xml contains
<jee:jndi-lookup id="entityManagerFactory" jndi-name="java:jboss/pu/pc" />
Any other better suggestion is more than welcome!

In the standalone.xml file remove the prefix java:. Then in persistence config file reference the jndi name you have in your standalone.xml but with the prefix. So:

I am able to connect to the db using pgAdmin III from my laptop.
Also, I am learning Spring, and I see some beans are wrapped in the profile "prod", but I cannot tell anywhere in code or web.xml that uses a particular profile.
Does the application server (Heroku?) need to start in a particular mode/profile, could that be why the db connection is not opening?
I'm learning Heroku as well.
Are you trying to run application on local machine? To be able to run this sample project on your local machine, you need to have database created. It's not described in the tutorial but if you try to use sample DATABASE_URL (postgres://scott:tiger#localhost/myapp) you need to create user scott with password tiger and create database myapp and grant scott required privileges. What I did, I've created sampledb database with existing postgres user, since it's database admin, I don't need to bother with grants and just changed url to
export DATABASE_URL=postgres://postrges:<password>#localhost/sampledb
Using JBoss 4.0.5, JBossMQ, and Spring 2.0.8, I am trying to configure Spring to instantiate beans which depend on a remote JMS Queue resource. All of the examples I've come across depend on using JNDI to do lookup for things like the remote ConnectionFactory object.
My problem is when trying to bring up a machine which would put messages into the remote queue, if the remote machine is not up, JNDI lookup simply fails, causing deployment to fail. Is there a way to get Spring to keep trying to lookup this object in the background while not blocking the remainder of deployment?
Iit's difficult to be sure without seeing your spring config, but assuming you're using Spring's JndiObjectFactoryBean to do the JNDI lookup, then you can set the lookupOnStartup property to false, which allows the context to start up even if the JNDI target isn't there. The JNDI resolution will be done the first time the ConnectionFactory is used.
However, this just shifts the problem further up the chain, because if some other component tries to get a JMS Connection on startup, then you're back where you started. You can use the lazy-init="true" attribute on your other beans to prevent this from happening on deployment, but it's easy to accidentally put something in your config which forces everything to initialize.
You're absolutely right. I tried setting lookupOnStartup to false and lazy-init=true . This just defers the problem to the first time that the Queue is attempted to be used. Then an exception as follows is thrown:
[org.jboss.mq.il.uil2.SocketManager] Failed to handle: org.jboss.mq.il.uil2.msgs.CloseMsg29702787[msgType: m_connectionClosing, msgID: -2147483606, error: null]
java.io.IOException: Client is not connected
Moreover, it looks like the lookup is never attempted again. When the machine with the remote queue is brought back up, no messages are ever processed subsequently. This really does seem like it should be well within the envelope of use cases for J2EE nonsense, and yet I'm not having much luck... It feels like it should even maybe be a solved problem.
For completion's sake, the following is the pertinent portion of my Spring configuration.
