What is the OpenJPA configuration to view SQL query executed in a database? I would like to view the query with all parameters executed in log or console instead of viewing the JPQL query
<property name="openjpa.Log" value="SQL=Trace" />
Enables logging of all SQL statements, minus parameter values.
<property name="openjpa.ConnectionFactoryProperties" value="PrintParameters=true" />
Enables logging of SQL parameters.
Logging documentation
If you're using log4j, you can setup your log4j.properties file as follows, which will display both the native SQL query and any parameters:
log4j.rootLogger=WARN, CONSOLE
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%-5p %t %d{ISO8601} %l - %m%n
log4j.category.openjpa.jdbc.SQL=TRACE
To configure Open JPA for Log4J, you need to do the following in persistence xml
Open JPA Configurations
{'property name=”openJpa.Log” value=”log4j”'}
Log4j properties for Open JPA configs
log4j.logger.openjpa.Query=TRACE
log4j.logger.openjpa.jdbc.SQL=TRACE

Hi I want to add running persistance.xml file

In addition to Rick's answer, there is also the "openjpa.ConnectionFactory2Properties" property for connection factories used for unmanaged connections. (more details here: https://openjpa.apache.org/builds/1.2.3/apache-openjpa/docs/ref_guide_conf_openjpa.html#openjpa.ConnectionFactory2Properties)

I'm looking to be able to enable or disable the eclipselink shared cache (second level cache) via the jboss-cli.
We generally have the shared-cache-mode set to DISABLE_SELECTIVE, but in certain deployments we would like to be able to disable it. It would be nice if we could do this via the jboss-cli and avoid editing our persistence.xml.
Anyone got any ideas or experience doing anything similar?
I've included our persistence.xml below. I'd be happy to provide anything else that might be helpful.

In case anyone else ever attempts to do this...
Edit your persistence.xml, setting the shared-cache-mode to a variable as follows:
<shared-cache-mode>${SHARED_CACHE_MODE}</shared-cache-mode>
Then you can add this variable into your standalone.xml by sending the following command to your jboss-cli (substituting DISABLE_SELECTIVE as appropriate):
/system-property=SHARED_CACHE_MODE:add(value=DISABLE_SELECTIVE)
The following article helped us a lot with this: http://www.mastertheboss.com/jboss-frameworks/hibernate-jpa/jpa-configuration/how-to-use-an-env-variable-in-your-persistencexml

As you can see I have provided jdbc url for connecting to the database. However, when I run my application I get the following information.
14:31:57,377 INFO [org.eclipse.persistence.connection] (default task-2) Connected: jdbc:h2:mem:test
User: ROOT
Database: H2 Version: 1.3.173 (2013-07-28)
Driver: H2 JDBC Driver Version: 1.3.173 (2013-07-28)
which states that I connected to jdbc:h2:mem:test and consequently I cannot perform the desired actions.
It makes me think I am connected to a wrong database?Am I missing something? How can I actually connect to the db that I want?
I am using Wildfly 10 and EclipseLink. Not using Maven.
Assuming you're using container-managed em, you should define your data source in Wildfly configuration (standalone.xml). You should then refer to your datasource using the persistence-unit.jta-data-source (or persistence-unit.non-jta-data-source) tag in your persistence unit definition.
If you need both the MySQL and H2 data sources, you can create multiple persistence units and differentiate between them using #PersistenceContext(name = "...")
1.You need to add mysql driver to Jboss like here : Can't add mysql driver to jboss
or here
https://synaptiklabs.com/posts/adding-the-mysql-jdbc-driver-into-wildfly/
You need add mysql datasource in standalone.xml configuration file like here :
https://zorq.net/b/2011/07/12/adding-a-mysql-datasource-to-jboss-as-7/
<datasource jndi-name="java:/mydb" pool-name="my_pool" enabled="true" jta="true" use-java-context="true" use-ccm="true">

I am working on a project where I am using play framework along with mongo db. As of now I have hardcoded the value for local db connection in persistence.xml file and given the jpa.default value as persistenceUnitName and I am using the play's JpaApi for the db operations (which inherently uses the entity manager).
I am not able to identify how to define environment (prod, dev, stage) specific db properties like host, url etc. in application.conf or any other file.

There would be different solutions. It depends on your environment.
If you are using WildFly / JEE container, you can configure a WildFly NoSQL subsystem, providing there the references to the remote datastore. It would be the equivalent of a SQL datasource, but for a NoSQL datastore. See Using WildFly NoSQL
If you are using a web container, there would be different strategies.
You can create different war(s), one for each environment, for instance using maven profiles.
Alternatively, you can configure your Spring context in order to use an external property file. See this question.
If you deploy it in a PASS, such as OpenShift, you can mount the persistence.xml file as a config map. See Config Map - OpenShift doc
It'll be weeks that I'm stuck with EclipseLink. I can not persist an object in my database. I use netbeans 7.3. I encountered this problem when I started designing a web application. What follows is the approach I have adopted. It may be that I do without me realize a mistake.
After that netbeans has finished generating the project files I configured the jndi. Then I converted automatically with netbeans, the database tables in entity object.
here is the link
then, from these classes, I created their JPAController . (Always automatically with netbeans)
and finally, as a test, I just instantiate the description of "Outils" and leave the fields empty id. Since the latter automatically increment in the database, if the persistence is done well, I should have an id when I appear with out the console.
<body>
<h1>Hello World!</h1>
<%
Outils o = new Outils();
o.setDesignation("hammers");
EntityManagerFactory emf = Persistence.createEntityManagerFactory("Test_EclipseLinkPU");
UserTransaction utx = (UserTransaction) new InitialContext().lookup("java:comp/UserTransaction");
OutilsJpaController o_ctrl = new OutilsJpaController(utx, emf);
o_ctrl.create(o);
out.println("this is the id of hammer " + o.toString());
%>
</body>
and I get as result: Outils[ id=null ].
I have no error or on glassfish even less about the debugger.
Ps : Here are the persistence.xml file

Thank you for your future is in your answers and listening for any additional information.
(Not really an answer but I couldn't show this in a comment)
To increase logging your persistence.xml should look like this:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/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">
<persistence-unit name="Test_EclipseLinkPU" transaction-type="JTA">
<jta-data-source>test_data_source</jta-data-source>
<exclude-unlisted-classes>false</exclude-unlisted-classes>
<properties>
<property name="eclipselink.logging.level" value="FINE"/>
<property name="eclipselink.logging.level.sql" value="FINE"/>
<property name="eclipselink.logging.parameters" value="true"/>
</properties>
</persistence-unit>
</persistence>
You need to commit or flush the transaction before anything will be written to the database. If you are using IDENTITY sequencing (I strongly recommend not using IDENTITY, use TABLE or SEQUENCE if db supports it), then the Id cannot be allocated until the insert occurs, so a persist() will not assign the Id (as it does for TABLE and SEQUENCE).
What does your create() method do? How is your Id mapped?
I am using EclipseLink libraries in eclipse (at dev time) and deploy on TopLink, I need to show the generated sql statement.
I am using the following persistence.xml:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0"
xmlns="http://java.sun.com/xml/ns/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_1_0.xsd">
<persistence-unit name="myPUnit" transaction-type="JTA">
<provider>
oracle.toplink.essentials.PersistenceProvider
</provider>
<jta-data-source>jdbc/dcds</jta-data-source>
<properties>
<property name="toplink.cache.shared.default" value="false"/>
<property name="toplink.logging.level" value="FINE" />
</properties>
</persistence-unit>
</persistence>
I know it should show generated sql statements, but this is not the case.
To see the SQL for a JPA Query you can enable logging on FINE or lower.
To get the SQL for a specific Query at runtime you can use the DatabaseQuery API.
Session session = em.unwrap(JpaEntityManager).getActiveSession();
DatabaseQuery databaseQuery = ((EJBQueryImpl)query).getDatabaseQuery();
databaseQuery.prepareCall(session, new DatabaseRecord());
String sqlString = databaseQuery.getSQLString();
This SQL will contain ? for parameters. To get the SQL translated with the arguments you need a DatabaseRecord with the parameter values.
Session session = em.unwrap(JpaEntityManager).getActiveSession();
DatabaseQuery databaseQuery = ((EJBQueryImpl)query).getDatabaseQuery();
String sqlString = databaseQuery.getTranslatedSQLString(session, recordWithValues);

As a workaround, find generated SQLs here:
app_serv_home\j2ee\home\log\oc4j\log.xml
