I've created a spring project which I later deployed on glassfish, the ap is working at first. But when I added persistence.xml it took mins to be done with error.

When browse: http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd, it wouldn't load.
Any idea or work around on this issue?
I think it's related with the whole java.net, java.sun.com, project Kenai etc. being down because of the maintenance reasons.

I'm trying to set JDBC timeout via persistence.xml, but it doesn't work.
This is how my persistence.xml looks like:
<persistence-unit name="persistenceUnit" transaction-type="JTA">
<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
<jta-data-source>OracleDataSourceExample</jta-data-source>
<properties>
<property name="oracle.net.READ_TIMEOUT" value="1"/>
<property name="oracle.jdbc.ReadTimeout" value="1"/>
<property name="oracle.net.CONNECT_TIMEOUT" value="1"/>
</properties>
</persistence-unit>
So, does anyone have suggestion what to do? (how to set jdbc timeout)

The problem is in your configuration
<properties>
<property name="hibernate.hbm2ddl.auto" value="create-drop"/>
</properties>
The correct value would be validate

I am learning JPA.
I tried the Spring-JPA-Hibernate combination.
The application works and I get the results.
But though there is only 1 record in the database, it is taking about 4 to 5 minutes to load the page.
Not quite sure what I am doing wrong.
I Googled for the same but all I am getting are performance optimization suggestions but I think I am missing something more basic as there is only 1 record in my table.
Here are the details:

I am using Spring 3 and Hibernate 3 jar files.
I tried replacing Hibernate with Eclipselink and the applications works perfect. Its only when I use JPA with Hibernate that I have slowness issues.
Here are the jars I used with Eclipselink and Hibernate:
Eclipselink:
eclipselink.jar
javax.persistence_2.1.0.v201304241213.jar
javax.persistence.source_2.1.0.v201304241213.jar
Hibernate:
ejb3-persistence.jar
hibernate-annotations.jar
hibernate-commons-annotations.jar
With Eclipselink, this is how my persistance.xml looks:
<?xml version="1.0" encoding="UTF-8" ?>
<persistence xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"

Not sure what I am missing.
I had this performance problem on Windows 7 Desktop.
However, I did not face this issue when tried on a Windows 8 Machine with identical code and database.
Did not find the root cause but solved my problem for now.
I am writing unit tests for my Spring application using in-file HSQL db. I don't want to pollute this db with test data, so I am trying to set up another in-memory HSQL db instance to be used in tests.
In my abstract testing class I import test application context XML configuration:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration("/testingContext.xml")
#Transactional
public abstract class AbstractDaoForTesting {
testingContext.xml

Up to now in-memory HSQL db is working fine in test.
However, as soon as I introduce in my project persistence.xml in src/main/resources/META-INF unit tests start to use this persistence unit and not the one from testingContext.xml.

What's wrong with this configuration? Why tests "prefer" to use db defined in persistence.xml?
Your problem is a perfect example for Spring profiles. It is always problematic to have multiple beans doing the same thing in your context at once if you want a certain one to be used.
You should have two different profiles, "prod" and "test", and wrap your bean declaration in the xml config accordingly with <beans profile="XYZ"> ... </beans>. A more extensive example can be found here.
You can then annotate your test with #Profile("test") and it should use the correct database.
I'm working with JPA(Hibernate) and spring project these days, I configured spring, jpa and try to deploy the application on tomcat7, As I know jpa/hibernate creates tables using entity class first loading, but here I couldn't see any connection between database and application when applications starts, below you can see my configuration,I have seen lot of questions posted regarding this matter, I couldn't find the proper solution to my problem.
Can any one tell me what is the problem here.I have created a application without any issues in jetty server sometime back,
Thank you in advance

I think there is no issue with your configuration, try after removing "default-lazy-init=true" attribute
Cheers
try changing:
<property name="hibernate.hbm2ddl.auto" value="validate"/>
to:
<property name="hibernate.hbm2ddl.auto" value="update"/>
or:
<property name="hibernate.hbm2ddl.auto" value="create"/>
