Using Hibernate as a CacheStore for Coherence

I am trying understand the coherence function for my project new requirement.
I've developed small application Using Hibernate as a CacheStore for Coherence
(http://wiki.tangosol.com/display/COH34UG/Using+Hibernate+as+a+CacheStore+for+Coherence)
I tried to remove the object from cache Using NamedCache.remove(Object) method.But object got removed from database and cache as well.
I don't want to remove from database table.
Is there way to remove the object only from cache and retain in the table???
Thanks
Kaleem

Sure -- you can extend built-in HibernateCacheStore and override erase/eraseAll methods as no-ops.

Can HotCache use Hibernate

I have been teaching myself the new Oracle Coherence HotCache technology & am playing around with it.
I have a question about the JPA implementation. From what I have read, HotCache is built on TopLink & uses the JPA mappings metadat to update the cache from the database. Does that mean that the application using it HAS to be using TopLink. Would something like Hibernate work?
Thanks!
Nidhi

Of course, you can use Hibernate as the CacheStore / CacheLoader of Coherence, or you can use Coherence as the second layer cache of Hibernate.

Any tutorial for using Hibernate in Jdeveloper?

Hi
thank you for reading my post
is there any tutorial that helps with using Hibernate with Jdeveloper?
specially the ant task stuff about schema generator and Hibernate annotation?
Thanks

thanks in advance for your response.

When we use jsf can we also use hibernate or ejb for database visting.

Using Hibernate as a Custom Component

I don’t know whether this question is appropriate in LC context.
Our scenario, We have very complex logic in each of JDBC store/retrieve activity in the process. We would like to move this part into Hibernate based custom component.
We tried with simple Hibernate persistence class but it seems to be LC not loading them.
1) Is this the restriction with LC? (using hibernate as a custom component)
2) What is the appropriate solution?
You help is highly appreciated

Jasmin,
Is your class included in the custom component?
Yes, It is a annotated entity class,
When creating sessionFactory it is not loading the class.
i'm using flowing code block for creating sessionFactory,
factory =
new AnnotationConfiguration().addAnnotatedClass(dao.entity.UserEntity.
class).setProperty(
"hibernate.dialect",m_dialect ).setProperty(
"hibernate.connection.driver_class", m_driverClass).setProperty(
"hibernate.connection.url", m_connectionUrl ).setProperty(
"hibernate.connection.username",m_userName).setProperty(
"hibernate.connection.password", m_password).setProperty(
"hibernate.hbm2ddl.auto", m_hbmTodll ).setProperty(
"current_session_context_class",m_contextClass ).configure(resource).buildSessionFactory();
Is the jar referenced in the class patch section of the component.xml?
Yes , I have tried for this approch too , but class is entity class is not loaded.

Hi All,
I need to use the Existing Hibernate API's and pass it on to the JCAPS oracle eWay to persist the Data.
As the present Application is using the Hibernate for persisting the Data as we have parent child relation with multiple tables , so we need to push the whole thing in to JCAPS.
Thanks & regards

Hi,
You cannot use hibernate using oracle or any other database eWays. If you want to leverage the same or the existing code you have for the Data Access you use JCD.
So what you can do is have the required jars available for the application and then use the available classes with in the JCD.
Thanks,
NarayanaaI don't think that is secesarily true. You can use oracle eWay to handle the database connection, pooling and XA transactions. You just retrieve the java.sql.Connection object from the eWay and use that in you hibernate code.

About using hibernate with mysql

hi all,
i have used hibernate with hsqldb(database given by default) and it works fine.but when i tried to use it with mysql then i have encountered a problem
xception
org.hibernate.TransactionException: Transaction not successfully started
     org.hibernate.transaction.JDBCTransaction.rollback(JDBCTransaction.java:149)

     javax.servlet.http.HttpServlet.service(HttpServlet.java:810)
though i have put jar file of mysql in lib directory and changed the driver name in hibernate.cfg.xml.
can any one place some example illustrating the steps involving.thanx

Hi smogura,
Thanks for the message. Ok I did as you told. I believe I went to the right place:
Resource->JDBC Connection pools. However I wasn't sure how exactly to go about setting connection pools,
so I went to the web and did a search and I managed to get hold of this
website:http://www.albeesonline.com/blog/2008/08/06/creating-and-configuring-a-mysql-datasource-in-
glassfish-application-server/
I followed from steps 4 onwards. However at step 14, I did not get a sucesfull ping. The values I used are as follows:
General:
Name:               MySQL
Datasource Classname:     com.mysql.jdbc.jdbc2.optional.MysqlConnectionPoolDataSource
Resource Type:           javax.sql.ConnectionPoolDataSource
Advanced Properties:
databaseName:      ebooking
ServerName:     GlassFish
URL          jdbc:mysql://localhost:3306/ebooking
password          *****
user:          1234
I am not sure what is wrong, by the way, I am using Glassfish V3 that comes bundled with netbeans. Any idea what's wrong or missing? Thanks

Problems building JavaDoc of classes using Hibernate/javax.persistence

Hallo!
I am trying to create the javadoc of classes that use hibernate. First it starts of with error messages like

See [http://forums.sun.com/thread.jspa?threadID=5333060&tstart=0]. In general, if you use third-party libraries in your code, you should include these libraries in Javadoc's classpath option when generating documentation.

I am using MyEclipse IDE.Doesn't matter.
Have you looked at the Hibernate Docs, website, and forums?

Hibernate Query vs PreparedStatement for SQL

Hi,
I am using Hibernate for DAO classes, which i am using for the basic CRUD operations. But for complex queries with complex joins i am writing the SQL.
In such case whether it is better to use the Query.createSQLQuery(String sql) to invoke the SQL or better to use the PreparedStatement since i am invoking only the SQL as supposed to HQL by getting the connection from the Hibernate Session. Since the PreparedStatement is precompiled it may be faster than invoking the SQL through the Query.createSQLQuery(String sql)? or using the Session.getNamedQuery(QUERY_NAME)? Please let me know your opinion on this.
Thanks

Whether you use Hibernate, ODBC, BDE, or Funky Foo's SQL client library, Oracle does not give a damn.
It receives a statement from the client. This can either be SQL or an anonymous PL/SQL block. It parses it as a cursor. It then provides the client with a cursor handle to reference the cursor.
The cursor is essentially a program. If it has bind variables, it is a program that accepts parameter input. This allows the very same program to be executed multiple times with different input parameters. For example, executing the same INSERT SQL cursor for different values and inserting multiple rows using the very same cursor.
A cursor can also (like a program), produce output. An example is a SELECT cursor - where the fetch interface of the cursor enables the caller to consume the output of the cursor.
So what is optimal in this respect? First and foremost cursors that are created using and used with bind variables. Secondly, re-using the very same client cursor handle (and not just the same server side SQL cursor) where possible (e.g. like repeating the same SQL INSERT statement with different values).
The question to asked is whether the method you select to use on the client side - be that Hibernate or Funky Foo SQL, support this?
The consideration to make is the following. Why code SQL in the client side? SQL is executed on the server-side - refers to server side data structures and needs to be tuned on the server. Put that code in a client and it significantly increases the complexity and decrease the flexibility of SQL.
The alternative (and recommended approach) is to use PL/SQL to encapsulate all SQL. Instead of the client (and client programmer) needing to know SQL, a PL/SQL call interface is provided with calls like GetInvoice() to return a single specific invoice, or GetInvoiceByDate() that returns selected invoices for a date range. The PL/SQL code creates the SQL cursor and returns the client cursor handle as a reference cursor to the caller.
This also allows business and validation logic to be implemented in the PL/SQL call interface to protect data integrity and business transaction sanity. A database structure change requires the SQL inside a PL/SQL procedure to be changed - without having to touch the client code. Likewise, SQL can be tuned and improved without having recompile a single byte of client code. And the same PL/SQL call interface services all clients - unlike multiple Java clients duplicating the same SQL (and not always correctly) to do the same thing, or having to duplicate and repeat the same data validation and business rule logic.

Using Hibernate on OC4J 10.1.3

How can I use hibernate in my application server, anyone has a reference?
Thanks.

There's an easy way if you don't need hibernate to be working behind the scene (e.g, replacing TopLink as the JPA implementation).
Basically, you just need to initialize hibernate SessionFactory once on startup, and put it somewhere accessible from your business logic code.
On servlet container, usually you would want to attach a ContextLoaderListener and initialize hibernate there and put it in ServletContext. You can then get sessionFactory from your servlets using httpServletRequest.getSession().getServletContext().
Same idea for ejb. I'm not sure how to accomplish that though. Maybe instantiating the sessionFactory in a startup listener and register it on JNDI. I'm not sure, still learning all these EJB stuff.

Configure webservices as datasource for coherence

Is it possible to directly configure webservices as datasource for coherence. So that after a preconfigured period of time, the cache refreshes itself. If yes samples/ documentation for the same.

Hi Tally,
you can do almost that, but not exactly that with out-of-the-box features only.
You can use the refresh-ahead feature of the read-write backing map with which a get to a key will cause the refresh of the entry value from the cache loader which will be seen by the subsequent get to the same key.
Alternatively you can schedule your own periodic processing with some timer which fetches data from the backing storage and it puts it into the cache.
A mix of the two would be to have the periodic processing issue the get requests which trigger the refresh-ahead behaviour.
Best regards,
Robert

Hibernate all workstations idle for at least 30 minutes, after 10:00pm

Recently i came a across a challenge launched by my boss: Hibernate all workstations idle for at least 30 minutes, after 10:00pm.
By GPO, i can. So, i wrote a script.
I'm using a System.Runtime.InteropServices;
I'm not good in scripts, for this i need help to improve it.
Please, help me. Thank you.

You ask for help improving a script that you already wrote, but you don't provide said script, nor tell us which part of the script you're having difficulties with... This makes it a bit hard to help you...
Still, I would not suggest going down the route of creating a script for this. Yes it can obviously be done, but there are mechanisms out there that are already more appropriate for handling such things which do not involve re-inventing the wheel: GPO and
Scheduled Tasks are two of them.
If you create it as a *pure* script with no "help" from outside applications, you need to consider these things:
- How do I deploy the script to every machine?
- The script will need to be running in the background the whole time, from the time the computer starts up until it shuts down (it will sit idly doing absolutely nothing until it's past 10:00, but it will be running in the background nonetheless).
- How do you ensure it's running properly?
- Who will support it going forward?
If you use a GPO, you don't have to worry about any of those things (except about how to tell whether it's running properly).
Alternatively, you could also create a scheduled task which kicks off at 10:00 daily with a condition of only start if computer is idle for over 30m where the command that it executes is to hibernate the computer. Scheduled tasks can also be created by GPO,
so you don't have to worry about many of the things you would normally have to worry about if you were using a script.
Again, don't try to re-invent the wheel unless there is some benefit to it. From what you told us about your requirements, there isn't in your particular case.

I want to use hibernate with the tomcat

I want to use hibernate with the tomcat server can it be possible and if yes then what is the stepwise way.
Infact I know the java JSF but want to command on Hibernate plz help me.
I'll be thankful to you.

To be honest, I wouldn't even know where to start. Do you know what Hibernate does and how it works? Do you know how Tomcat works? All you'd need to do to combine those two would be to let Tomcat provide the DB connections for Hibernate, I suppose. Neither of those products are a topic of this board though.
