As per "http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=458&get_params=p_track_id:JEE5EA" do we have a prerequisite to do one course ? is this mandatory?
More of Architectural Design Principals that form the basis of Design Patterns then!

Nice to hear and would definitely be interested to go through!
Also wanted to know whether this book will help me to prepare or browse through for my Oracle Enterprise Architect examination :-)
What does this book target?
Core Java Patters [GoF] like Creational, Structural, Behavior --or--
Enterprise Patterns like the ones shown in SCWCD forums like ValueObject, MVC, Front Conntroller et al --or--
Pattersn used by popular frameworks like Spring et al --or--
Architectural Patterns --or--
Mix and Match of the famous/important ones from all of the above?

I am happy and excited to read this book as it says "50 page ebook", something that will serve as a quick reference and a handy one too. Is this like RefCards one ? Excited to see this...


Thanks!
Mani
Does this book, talk from requirements to maintenance and architectural patterns/concepts that architects need to have in mind when going through each phase?

Hi

Our DB recently migrated from Oracle10g to 11g. Our application is a groovy/grails application deployed in tcServer. This app was working without a dialect declaration in Oracle10g.

But now we get
===
org.codehaus.groovy.grails.orm.hibernate.exceptions.CouldNotDetermineHibernateDialectException: Could not determine Hibernate dialect for database name [Oracle]!
at java.security.AccessController.doPrivileged(Native Method)
===

I added dialect='org.hibernate.dialect.Oracle10gDialect' to datasource.groovy to make the app work. But this means I will have to redeploy the application and we have lot of grails applications all now pointing to 11g database.

Is there a easy way to mention this dialect configuration somewhere else, like wrapper.conf, which will just need a tcServer restart and not an app deploy?

I tried
===
wrapper.java.additional.16="-Dhibernate.dialect=org.hibernate.dialect.Oracle10gDialect"
===

but this didnt work. Please help.

Thanks!

Hi,

I have logged into the tomcat admin console and created an environment entry under "resources" link.

HOwever the code that reads this entry using System.getProperty() or System.getenv() returns null.

any idea, where is the gap?

Thanks!

Got it working.

Just remove all those System.setProperty that has "com.ibm." kind of settings. Just keep the keyStore and trustStore settings and it works for sun jre.

Dear All,

I have the below set up configurations done in my stand-alone java client program, to talk to a HTTPS enabled 2-way SSL server application. This works fine in a IBM JRE.



But when I run the same client program in Eclipse under a Sun-JRE, I get into an error saying
===
Exception in thread "main" java.io.IOException: Error occured when communicating : java.net.SocketException: Unconnected sockets not implemented
===

I have the below questions:

  • I believe the configurations for keyStore and trustStore from the above set still holds good for Sun-JRE as well. Or is it different?
  • Are configurations that use "com.ibm.*" above needs to be changed to Sun specific ones?
  • Does it make any difference to create the keyStores and trustStores using Sun JRE or IBM JRE ?


  • Any help will be useful.

    Thanks!

    Dear All,

    In the Web Services Book by 'Richard Monson Haefel' I read about UBR registry for UDDI. It is a registry hosted for public usage. When I googled on that, I could see that it has been decommissioned now. Is that true? Do we have any other registry which I can play against to learn UDDI structures?

    Also, I see RAD 7.0 has a local UDDI to which we can host a service. But my intention here is not to host a service but to learn UDDI objects. I want to run SIMPLE stand-alone java programs that use JAXR to talk to UDDI. How can I just turn this local UDDI ON and try my programs against it? Can you help me please?

    Wishing you all a Very Happy New Year - 2009!

    Hi,

    I just got the array of java.security.cert.X509Certificate associated with the HttpServletRequest to get hold of the certificate, inside my web service.

    The code:



    Thanks a lot, Set!

    Hi

    I have a web service which I have made secure. The client and theservice go though a 2-way SSL handshake before communicating with each other.

    At the server side,

    When I try httpReq.isSecure(), I get "true"
    When I try httpReq.getAttribute("javax.net.ssl.cipher_suite"), I get "SSL_RSA_WITH_RC4_128_MD5"

    But, when I try httpReq.getAttribute("javax.servlet.request.X509Certificate"), I get "Null".

    When I print httpReq.getAttributeNames(), I dont see this attribute as well.

    Why is this so? What could be the error? How should I go about getting the certificate?

    Thanks!

    I am yet to research on this :-) But I have heard that we can have a 'Trust Association Interceptor' do this.

    Looks like I need to think more on this side. But you can just let me know on the steps that you feel, I should go about. I will see what in WebSphere we have in analogy to that!

    Many Thanks for your help.

    Thanks. I use, Websphere Application Server 6.1.0.x

    How should I go about my first question now?
