Re: GWT with Hibernate and Oracle

2011-02-08 Thread Debashish

Hi Néstor,

I have followed all the steps which required a Hibernate application
to work.
And this sample hibernate module is working fine without GWT as UI.

However while connecting to any Database we need to put Driver class
in the classpath and
hibernate also requires the Classes12.jar or ojdbc14.jar at it's
classpath.
This is required so that it can understand the driver property placed
in hibernate.cfg.xml file
property
name=connection.driver_classoracle.jdbc.driver.OracleDriver/
property

And probaly this class is not allowed in Google APP and I am getting
an error as
---
Caused by: java.lang.NoClassDefFoundError: java.net.Socket is a
restricted class. Please see the Google  App Engine
developer's guide for more details.
---

*** This is the local database in my case and I am absolutely getting
no way to resolve it.

Please sugggest me if any other approach / websites to follow for
this.

Thanks
Debashish

 Hi

 I checked the link that you sent and this is will work of course but you
 will have to create a lot of DTO objects for your application and map the
 POJO objects from Hibernate to the DTO which will require a lot of coding.
 The example should work, your DTOs should be serialized, Now what I don't
 understand is that if you're using Hibernate why use JDBC directly?. You can
 get a Connection to your database from the Session object or create an a
 SQLQuery. From what I'm reading it looks like you're using java.net.Socket
 on the GWT Client side and this is not a valid class.

2011-02-08 Thread Néstor Boscán

Oh Sorry Debashish

I see that you're working with Google App Engine. I've worked with Google
Web Toolkit and Hibernate for standalone applications, not applications that
are deployed on Google App Engine. The link that you sent me is for Google
Web Toolkit + Hibernate. I imagine that Google App Engine has restrictions
on the classes that you can use, in this case java.net.Socket. I think, and
again I'm no expert on GAE, that you can't use any database you want, you
have to use the database that the GAE documentation describes. If it's
something like BigTable, I don't know if you can use Hibernate on top of
that. I think that I read an article on using Java Persistant Architecture,
which is an abstraction of what Hibernate does, with GAE.

I am trying for a sample using GWT and database layer as Hibernate
with Oracle on Google Aps server.

I have done a sample for Hibernate with JSP as presentation layer,
which is working fine.
But the same approach is not working with GWT.

Here is a verygood link on this topic

http://code.google.com/webtoolkit/articles/using_gwt_with_hibernate.html
and my approach is almost similar.

I have added the jars necessary for the Hibernate layer (and
classes12.jar for oracle driver).

However while running , it is giving me an error as below,

I have one through some of the threads which suggested me to download
the google apps jar files and try it. I have downladed it. but there
is no proper direction on how to make use of which jar file.

Have anybody tried the same. Please let me know if anything I am doing
wrong.
*** Note that I am using Oracle 9.2 as local database.

Thanks
Dev
