Using EclipseLink or JPA with Oracle Coherence as shared cache

Hi,
I expect to use EclipseLink with Oracle Coherence as shared cache, mainly with/for Entity Caching.
* JPA)
For JPA queries, is the JPA semantics fully preserved when using Oracle Coherence ?
* Non-JPA)
Are the non-JPA API taking also advantage from Oracle Coherence ?
For these non-JPA queries, is the semantics fully preserved when using Oracle Coherence ?
Regards,
Dominique
PS: I hope this is the right forum to ask my questions.
Otherwise, could you tell me what is the right forum ?
Thanks.

Yes, JPA semantics are fully preserved when using TopLink-Grid to cache entities within Coherence.
Yes, the native EclipseLink APIs can also take advantage of TopLink-Grid and Coherence.
I am not sure what you mean by "For these non-JPA queries, is the semantics fully preserved when using Oracle Coherence ?" Perhaps you can provide an example of what you are looking for?

How to use JavaMail 1.4 with Oracle Application Server 10g (9.0.4.0.0)

Hi all,
I'd like to know if it's possible and how to use JavaMail 1.4 with Oracle Application Server 10g (9.0.4.0.0), Windows version.
With the following code, I can see that the mail.jar used by the server is the one included in the jdk installation :
// I'm testing InternetAddress.class because I want to use commons-email-1.2.jar that requires mail.jar 1.4 (or higher) and activation.jar 1.1 (or higher)
// and I know that inside the commons-email-1.2.jar file, I need to call the InternetAddress.validate() method that throws a java.lang.NoSuchMethodError: javax.mail.internet.InternetAddress.validate()V if it is used with mail.jar 1.2.
Class cls = javax.mail.internet.InternetAddress.class;
java.security.ProtectionDomain pDomain = cls.getProtectionDomain();
java.security.CodeSource cSource = pDomain.getCodeSource();
java.net.URL location = cSource.getLocation();
System.out.println(location.toString());
This code returns : file:/C:/oracle/app/jdk/jre/lib/ext/mail.jar and this mail.jar file has an implementation version number: 1.2
- I've tried to include my own mail.jar (1.4.2) and activation.jar (1.1.1) files in the war file that I deploy, but it doesn't work (the server still uses the same mail.jar 1.2)
- I've tried to put the mail.jar (1.4.2) and activation.jar (1.1.1) files in the applib directory of my OC4J instance, but it doesn't work (the server still uses the same mail.jar 1.2)
- I know that a patch exists : I've read the following document: How to Make Libraries such as mail.jar and activation.jar Swappable ? [ID 552432.1]
This article talks about the Patch 6514136, but this patch only applies to : Oracle Containers for J2EE - Version: 10.1.3.3.0
Can you please help me ?
Thanks in advance for your answers,
Laurent

I strongly suggest to upgrade to AS 10.1.3 to get this.
Think of future support of AS 9.0.4. You will get not critical patch updates anymore.

Can't use ";" in sql clause with Oracle 8.X

Can't use ";" in sql clause with Oracle 8.X
I can't use ";" at the ending of sql clause in VB program. First this program can use with Oracle 7.3.4 database. But now i need to upgrade DB to Oracle 8.1.7 ,program can't operate. It show error Runtime 40002
and 37000:ODBC driver for oracle/invalid charactor
Thankyou

I've seen a lot of discussion about semicolons in SQL
sent from 3rd party applications. A web search should
bring up the discussions.
Also you might get more response if you ask this question
somewhere else. This is not a VB forum, so you may

Using third party jars with Oracle Business Rules

We tried using the applib folder to load the jars but we are getting class loading errors.
When new instances are created, class loading is not happening.
Pls help.
Thanks

Are you using Application Server Release 3 or Release 2? There are different versions listed in your mail.
I think you probably want to add this as a shared library via EM and then import the shared library to your application with the application's xml config files.

Monitor PeopleSoft sessions with Oracle Coherence

Hello,
I installed Oracle coherence ( one Cache Server ) and two managed servers ( PIA1 and PIA2 ---weblogic 10.3.4).When trying to monitor peoplesoft sessions thru weblogic admin console ( Deployments - Peoplesoft - / - Monitoring - Sessions tab ) nothing displays or no session info . I have parameters ( monitoring - id and session-monitor-enabled = true ) included in weblogic.xml file. Can anyone please guide me here on what I missing ?

Yes I installed C*Web for weblogic session management when I login to Admin console under monitoring tab I can see the coherence servers under coherence tab but under sessions tab it display empty info ( ex it doesn't show who the user logged into the peoplesoft app) and I am not sure how to check the users logged info in the cache server.Can you please let me know if any parameters that needs to be checked wither in web.xml or weblogic.xml files.
thanks NJ for your response...

Oracle Coherence and OSB caching

Hi Guys,
I have a few queries regarding Oracle Coherence.
1. Is OSB business Service Caching internally uses Oracle Coherence.
2. If answer to above question is YES, then can I install Weblogic without Oracle Coherence.
3. Again if answer to above question is YES, will OSB caching work without Oracle Coherence and if yes, then How?
4. Can we create clustered weblogic domain without oracle coherence.
Regards

Thanks Durga/Abhinav,
The links clarify a lot.
Now what i need to know more is that when i installed Weblogic server (default configuration) and created a OSB server as managed server in wls domain. I could use the OSB caching in business services without any issue. However, there is no coherence server under "Coherence Server" in weblogic console. How the caching is working in OSB when i havn't configured any coherence server on weblogic?

How to use (toplink essentials)JPA with EJB 2.1 spec in oc4j 10.1.3.2

I have an application that uses EJB 2.1 spec with SLSB (no entity beans) and uses DAO pattern with hibernate2 for persistence. I want to replace hibernate with toplink-essentials (JPA). I cannot upgrade the EJB spec version as we use some thirdparty beans. The application uses DAO pattern so I should be able to hook in a new toplink DAO impl. What I am struggling with is how do I get hold of the EntityManagerFactory in my EJB 2.1 SLSB. Also I need CMT with XA transactions as our application interacts with jms and database using MDBs and SLSBs.
Prantor

You should be able to use Persistence.createEntityManagerFactory(<your-persistence-unit-name>, properties), and create your EntityManager from that.
To have TopLink integrated with JTA, in your persistence.xml (or properties) you need to use a JTA DataSource, and set the ServerPlatform for your JEE server.

Hi Joe !
I didn't get what you would like to point out. Actully, I am using same config.,
but not to disclose the info. I gave you @test and username/password xxx/xxx.Ok. Now, assuming your pool looks like what I showed, the issue is probably
that there are multiple Oracle driver zips around, and your standlaone program
is using a different, newer, better one than the server. Our weblogic jar files
include a classes12.zip Oracle thin driver, but there are multiple versions of
classes12.zip, and the latest from oracle is better than the one we sealed into
our packaging. Please use jave -verbose to identify exactly which Oracle sip file
you are using in the successful case, then make sure this zip file comes before
any weblogic stuff in your weblogic server's classpath, so we'll use the same
driver. This should work. Edit the script you sue to start weblogic to verify
the classpath does end up with the oracle driver ahead of all weblogic stuff.

no
weblogic code in the picture. Just make a JDBC connection using Oracle's

Help needed to use only SQR reporting with Oracle 10g

I have very old SQR reports (ver 2.28) that are still being used by connecting SQR to an Oracle7 DB. We have migrated the data from Ora7 to Oracle 10.2.0.4. The issue is that SQR 2.28 is not able to connect to Oracle 10.2.0.4. Hence I want to use the new version of SQR that is part of OBIEE.
I am not familiar with OBIEE and my interest is only using the SQR portion of it.
1. Can any one help me as to how to go about installing SQR portion of OBIEE on a Linux Itanium 64-bit box? My Oracle 10.2.0.4 DB is also running on the same box.
2. What are the minimum components of OBIEE I need to install to make use of SQR ?
3. Any other relevant information
Thanks.

When installing webgate, make sure the Access Server is running. You will get this error if Access Server is down or not reachable. ( Make sure from the machine where you are installing webgate you can ping to Access Server by Name).

Problem in using Weblogic 6.1 with Oracle 9i

Hi,

USING APACHE STURUTS BRIDGE WITH ORACLE PORTAL FOR STRUTS - JSR 168 PORTLET

I am trying to develop a JSR - 168 compliant portlet which uses struts framework.I am using APACHE STRUTS BRIDGE to run the application in my ORACLE 10.1.4 Portal server.While doing the configuration accoring to the documentation given in URL http://www.ja-sig.org/wiki/display/PLT/Struts+Bridge
(apache struts bridge), i was asked to add an <init-param> entery in the portlet.xml file to get the ServletContext.So i need to know where is the ServletContextProvider implementation class which implements ServletContextProvider available in Oracle AS so that i can use that to get the ServletContext and use it furthur.
Thanks
Deepak

you could write your own implementation class for the ServletContextProvider interface and fill in the portlet.xml with the class you class
It could be written as follows:
package Edmunds.com.portal.bridges;
import javax.portlet.GenericPortlet;
import javax.portlet.PortletRequest;
import javax.portlet.PortletResponse;
import javax.servlet.ServletContext;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletRequestWrapper;
import javax.servlet.http.HttpServletResponse;
