Thanks
Chetan
hi,

i went thru same problem of two prometeric ids. While giving part 3, promteric guy submited my exam without any answer while trying to skip advetizment. Then he created a new id for me and sent request to prometric center to merge both IDs.

Finally both were visible on sun certification database .

Yes, Class diagram is better to be tech agonostic. You can show managed beans to make class diagram representing complete solution but do not mark it as managedbean sterotype. For example, LoginCMD can be shown in class diagram and it can be implemented as struts action class or JSF managed bean.

For Sequence diagrams, it is better to show all classes like managed bean, service locator, POJOs. It is better to provide all details in SD to make things clear for developers.

I got result in 2 months time. I submitted around 25 march and complete part 3 also. Sent reminder email on 19 april and got result on 25 may thru email and finally on sun database site

For Part 2, i used Star UML.

Class diagram contains only business classes independent of technology. I did show controller classes as well but no mention of technology. Described services provided by each class and methods used in sequence dia.
High level component diagram --> Showing all high level components, external systems. Describe each compnoent with its services.
Low level component diagram --> Details XHTML/ManagerBeans/SSB/POJOs --> Specific to EJB 3 and JSF implementation

Deployment Diagram --> Described layout, details about how non functional requirements are achieved., Machine hardware and software recommendations.

Design patterns used

Sequence diagrams.
Risks --> define risks to business/project and mitigation plan.
Hi Guys,

I got email from oracle that i have cleared assignment certification. Thank you all for your suggestions and this very good forum

Hi all,

I have an MDB which receives remote location of file. I need to download that file from remote linux server to local file server. I am planning to use J2SSH library. Following are my options/thoughts:

1. Create SSHClient object at MDB startup. So there is one SSHClient (SSH Connection) per MDB. On every onMessage() method, i will open sftpChannel, download file and quit channel. On MDB shutdown i will disconnect sshclient. Now question is with increased load, number of SSH Connections will increase. Is it a good approach ??

2. Create a singleton class at startup which will create SSHClient. On every onMessage() method, I will get SSHClient from Singleton class and use it to create sftpChannel. Now i have only one ssh connection and using across all MDBs. How will it scale with increased load?

3. Create an Mbean which creates SSHClient on startup. On every onMessage() method, i will call mBean method which open sftpChannel and downloads file. Since mBean is single threaded then i can close / reconnect ssh client after n files download or reconnect in case of connection failure. I do not have to deal with multi threaded program. But i am thinking it may affect performance ?

Please share your thoughts on using j2SSH library?

Thanks and Regards
Chetan

PS Excuse me for posting same question in IO Streams forum as well.

Hi,

Today I went to write SCEA PArt 3. Promoteric person trying to skip SUN 's survey, he clicked clicked clicked and submit the test. So situation was, test was submitted without any answers.

Now he created another candidate ID and I wrote PArt 3 with new ID. He says he will send email to prometric center to merge both IDs.

Has any one faced this situation before? Please suggest what to do ? Any way out otherwise my work on part 2 will get scrapped because of him.

Thanks and Regards,

Hi,

I am using Star UML for drawing sequence diagrams. In SD, only method names are appearing. I am not able to show method arguments. Is there a way to show method arguments in SD using Star UML?

Thanks

Hi,

I am confused about SCEA part 2 coupon. I purchased coupon for level 2 for 12000 RS/- and downloaded assignment from web site. I am under impression that same level 2 coupon will be used for Level 3 also. I do not have to purchase level 3 coupon.

Is it right??? Or I do need to purchase separate coupons for level 2 & level 3 ?

If yes, then I think level 3 coupon should be purchased as soon as you are ready to upload because level 3 should be given immediatly after uploading level 2 assignment.

Please share your experiences on this.

Thanks and Regards,

Thanks Sudeepa.

Yaa I know that..Actually I was looking for sample assignments to check for prepardeness..

Please share your thoughts whether it is advisable to go directly for actual assignment from SUN without any practise?

If someone can share how delierables were produced, that will be great help.

Thanks and Regards,

Hello Everybody,

Are there any mock assignments for practising SCEA Part 2 readiness? I searched but they all point to paid ones.

Any help and suggestions for SCEA part 2 will be appreciated.

Thanks and Regards,

Congrats Buddy..

Hi,

Following is the scenario:

I have a web application built using Struts 1.3. Now we want to convert it to jboss portal.

Following are choices:

1. Write portlet classes and copy code from Action Classes and add to portlet classes.
- Advantage : Complete life cycle is portal based.
- Disadvantage : Struts application is no longer needed.

2. Use a struts portlet bridge
- Advantages - Still will be able to use Action classes with portal like look and feel.
- Disadvantage - I am not getting very comfort feeling with bridge as i am not sure full set features, industry practises. I have also read about certain limitations regarding (not able to user request.getParameter() style in JSP pages...)


Please share your thoughts/suggestions/experiences of using bridges.

Thanks and Regards,
