Migration from jsf 1.2 with spring to JSF 2.0

Hi guys,
I have a project written with JSF 1.2 and Spring IOC as bean container and i use Tomcat 6.20, now i see that a lot of people try jsf 2.0, my question is what exactly i need to move to JSF 2.0 , i did a little research and found out that i have to implement my own View scope if i use Spring , here is one implementation example http://cagataycivici.wordpress.com/2010/02/17/port-jsf-2-0s-viewscope-to-spring-3-0/.
have anybody try this solution?
so from where i have to start migration? is there any step by step document? the system is already in production and i have to evaluate the risks of migration.
i use myfaces implementation with richfaces and primefaces . will old tags work under jsf 2.0 ? Please provide me with some information .

so from where i have to start migration? is there any step by step document? the system is already in production and i have to evaluate the risks of migration.Do you actually NEED Jsf 2.0? The application is already working I presume, so it would seem a huge waste of time, money and effort to migrate it without a good reason to do so. If it isn't broken, don't fix it.
I'd wait until a new application needs to be implemented and then make the choice to use JSF 2.0. A review of all the changes done in JSF 2.0 can be a good place to start to make the decision.

Problem migrating from JSF Mojarra 1.2 to 2.0

As my subject suggests, I am having a problem migrating from JSF 1.2 to JSF 2.0.
As a first step, all that I had done was to replace both 'jsf-api.jar' and 'jsf-impl.jar' with the newer version 2.0 and restart my server.
As expected, server failed to publish with the following error message on the console. Any hint on solving this issue is highly appreciated.
The error message goes as below:

Don't you have some JSF 1.2 libraries around somewhere else in classpath? Appserver/lib? JDK/lib? Etc. You might have a mix of JSF 1.2 and JSF 2.0 in the classpath and the exception is just been caused by this collision.

Migrate from JSF to Struts?

Hi
I have seen some threads in this form regarding migration from Struts to JSF. Most of the posters back then (1999-2003) suggested starting with Struts and then migrating to JSF for production.
Now I have one year of experience with Struts in a Tomcat environment and practically no experience with JSF. My current job involves maintaining JSF code. The boss thinks migrating to Struts would make us independent of the company to whom the JSF project was outsourced.
I would like to know your opinion on migrating from JSF to Struts. How hard is it? Our architecture has Views, View Helpers, Business Context objects, Business Delegate objects, Business Processor objects, DAO (DB2, AS/400), DTO, etc. They seem rich enough semantically when compared with Struts that groups all these under MVC, even though they are complex to manage (job security :).
I'd appreciate your feedback.
Thanks
Murthy

To quote Ron Burdundy, "That doesn't even make any sense!" :) Seriously, though (and I admit a huge bias), that seems like a huge step backward. It seems the logic is this: "We outsourced the development of this system to someone else, and now we're left either maintaining it ourselves or paying them to do it, but, if we rewrite it with $FRAMEWORK, we'll be free of them." Is that right? How is maintaining a Struts app different (frameworks aside) from maintaining a JSF app? This is probably obvious, but that's a step I would neither take nor suggest. :)

I have a macbook 2.1 with osx10.6.8 and want to wipe it clean and migrate from my macbook pro with the same osx..is it possible to do?

I have an older macbook 2.1 intel OSX 10.6.8 that I want to wipe clean and then migrate from my macbbok pro with OSX10.6.8 to the older macbook, is it possible ,how would I do it..especially how do I wipe clean the older macbook?

Connecting to a TV is no different than connecting to any other external display. It's possible that there's a problem with the mini dvi port on the macbook r that you have bad adapters. You might try resetting the SMC Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support
Does the Macbook recognize that there's an external display connected when you look at the Display preference pane?

MIGRATING FROM JSF 1.2 TO JSF 2.0.1 WITH PRIMEFACES

HELLO!
I'm migrating to JSF 2.0.1 (mojarra 2.0.1) using PrimeFaces 2.0.
As I'm comming from JSF 1.2, I still have some libs in my project as jsf-facelets.jar, jstl.jar.
With JSF 1.2 I was using Tomcat v6 1.4, but I upgrated to Tomcat v6 2.0
I decided to use primeFaces for my uiComponents and this requires JSF 2.0
I install primeFaces.jar and download jsf-api.jar and jsf-impl.jar
I changed my config to 2.0 in my faces-config and the weapp works fine! I'm tryin' to Login using <p:commandButton> (from PrimeFaces) with action attribute, but when the app calls the action from my managedBean, an error appears....

so once the VM Enviroment is set for 11.1.2.1
i can just used the Essbase EAS Wizards
to bring the Applications and Other Objects into the new Enviroment 11.1.2.1
and then Export the Data from the old Enviroment 11.1.2
and import into the new Enviroment 11.1.2.1
Correct ????

Migrating from JSF 1.1 to JSF 1.2

I'm migrating an existing JSF 1.1 application that was based closely on the examples in the Core JavaServer Faces book. I'm having a very specific problem getting pages to render once I log into the application. Specifically the code associated with the TabbedPaneRenderer specified in chapter 9. The application worked fine under JSF 1.1 but after upgrading to 1.2 it seems that the functionality that was provided with the includePage method will no longer work.
The source code that was implemented is as follows:
   private void includePage(FacesContext fc, UIComponent component) {
     FacesContext     ctx        = FacesContext.getCurrentInstance();
     VariableResolver vr         = ctx.getApplication().getVariableResolver();
     ExternalContext ec         = fc.getExternalContext();
     ServletContext   sc         = (ServletContext) ec.getContext();
     UITabbedPane     tabbedPane = (UITabbedPane) component;
     String           content    = tabbedPane.getContent();
     ServletRequest request = (ServletRequest) ec.getRequest();
     ServletResponse response = (ServletResponse) ec.getResponse();
     try {
       sc.getRequestDispatcher(content).include(request, response);
     } catch (ServletException ex) {
       logError(ctx, vr, "Couldn't load page " + content + ": " + ex);
     } catch (IOException ex) {
       logError(ctx, vr, "Couldn't load page: " + content + ": " + ex);
   }This code is called from the encodeEnd method of the Renderer. Unfortunately the page that is being included never gets rendered. How should this be done in the JSF 1.2 implementation?
Thanks for the help...

Hello cmathrusse,
I just ran across the same issue. We were using JSF 1.1 and tomcat 5 and JDK 1.5 and and Tiles 1.1. We are migrating to JSF 2.0 JDK 1.6 and Tomcat 6 and our Custom Component also doesnt show up. I believe we are in the same situation.
Did you ever fig out the issue?
Thanks,

ESS Business Packages Migration from Ehp3 to Ehp4 with Custom Changes

Hello All,
We are using ECC 6.0 With Ehp3 and We have the following versions of ESS and MSS Business Packages Installed.
SAP_ESS 603 SP4
SAP_MSS 600 SP15
We have NWDI server also installed in this and made some Customizations in ESS Webdynpro Java based applications.
We have freshly installed a new portal development server with Netweaver 7.0 Ehp1 to cleanup unneccessary stuffs in our existing development portal server and pointed to the upgraded backend ECC 6.0 Ehp4.
The NWDI also installed freshly in the new server.
While upgrading, following Business Packages versions are recommended by SAP.
SAP_ESS 603 SP6
MSS 600 SP17
PCUI_GP 603 Sp 06
Now in the New portal server every applications works fine as delivered Out of the box and we are missing all the Webdynpro Java customizations which we have made as part of the Ehp3 based ESS Implementation.
We are in the process of Creating the New track in the New NW 7.0 Ehp1 server and import the .SCA files.
My Question is how can we get the automatic migration process, so that the Webdynpro Java Customizations which we have done in the Previous track in Ehp3 with different ESS SP level can be carry forwarded to our New NWDI Server.
How can we go ahead?. We are thinking of the following options and your suggestions are highly appreciated.
1. Import the .SCA files related to Ehp4 and do the Webdynpro Java changes manually again in the DCs of Newly created track    in the New NWDI server.
2. Is there a way to migrate a Track from One Server to another NWDI server with the Custom changes carry forwarded.
What are all the possible ways to achieve track migration to the new server with custom changes carry forwarded.
Appreciate your valuable inputs in this.
Thanks and Regards,
Sekar

Hi Sekar,
There is a cook book provided by SAP as attachment of note 872892. you can follow the process to have your custom DC's migrated to new Support pack of ESS/MSS.

DB2 Migration from Windows - Linux supported with Backup/Restore ?

Hi folks,
we have to do a DB2 V9.1 migration from Windows -> Linux. Both servers are Intel based. Is it official supported by SAP to do this without SAP migration tools? E.g. with a backup/restore or redirected restore? I heard about it, but i'm not sure.
Thanks a lot
Jochen
Edited by: Jochen Raab on Mar 1, 2010 5:40 PM

Hi Jochen,
Please have a look at the DB2 docu.
http://publib.boulder.ibm.com/infocenter/db2luw/v9r7/topic/com.ibm.db2.luw.admin.ha.doc/doc/c0005960.html
It clearly stats that Linux and Windows are not compatible.
DB2® database systems support some backup and restore operations between different operating systems and hardware platforms.
The supported platforms for DB2 backup and restore operations can be grouped into one of three families:
Big-endian Linux® and UNIX®
Little-endian Linux and UNIX
Windows®
A database backup from one platform family can only be restored on any system within the same platform family. For Windows operating systems, you can restore a database created on DB2 Universal Database (UDB) V8 on a DB2 Version 9 database system. For Linux and UNIX operating systems, as long as the endianness (big endian or little endian) of the backup and restore platforms is the same, you can restore backups that were produced on DB2 UDB V8 on DB2 Version 9.
So you need to do an eport/import.
Regards,
Joachim

Some clients migrated from 2007 is presented with the self signed certificate in 2013

I have migrated from 2007 to 2013. I did a couple of test migrations and on the ones with domain member computers Outlook is giving a certificate warning. The certificate they are presented with is the default self signed certificate on the 2013 server.
Even though I have added a trusted public certificate to Exchange and checked of to use With IIS.
I see that the default certificate is also checked of to use With IIS and it cant be removed in ECS. Shouldnt this be removed from IIS all together when adding a New certificate? And why does some Clients gets presented With the self signed and some With
the Public? For instance owa is presented With the Public cert. Also and Outlook I tested from outside the domain.
Regards

Only the UCC certificate should be bound to IIS.
Are any clients using POP or IMAP, which also use SMTP? In this case clients can be presented with the "wrong" certificate as well.

Migrating from messaging direct -- problem with read messages

Folks,
We are migrating from messaging direct's mail server. What I am doing is tar'ing up a user's account,moving it to the new server and untar'ring it. I them use mboxutil to create the folders and then make the '00' directory and number the messages appropriate and move then in. Then I run reconstruct on the mailbox and it works great. The problem is that all the messages are now unread. How do I make them read again???
keith

I had to do a similar migration from a different mail server. I migrated the messages to each user via IMAP, using a Perl script.
The Perl script would determine a few message states and set the IMAP flags appropriately.
I don't recall seeing anything in the docs about setting message states directly. However, in your case, it appears you already have the messages in seperate files. You could try loading via IMAP and setting the flags. I used the NetxAP perl module from CPAN. An alternative, there is an import utility for iMS2. I haven't used it, but you could convert the mail to UNIX mbox format and then load into iMS52.

Migration from jsf 1.1 to jsf1.2

I am trying migrate our application built on JSF 1.1 to JSF 1.2. I am facing lot of porblems during this migration.
Why are the tag classes marked final in JSF 1.2. We have many Tag classes written in our application overriding these tag classes. Is there any other way of overriding the behaviour of JSF 1.2 tag classes apart from overriding it.
I also see from the source code, that the tag classes are all generated code. Does it mean we can regenerate it using some build file and make the tag classes non-final.
Please help.
Thanks in advance,
Yetish

I agree to your point that we need program to an interface and not to an implementation class. But in JSF 1.2 scenario, even if we go ahead and implement it using object composition, we cannot use the Tag classes because of the fact that most of the important methods are marked protected (ex setProperties method of Tag classes) and hence cannot be invoked.
These methods can be overridden only by a subclass and we cannot subclass a final class.
I think if the idea is not to override a specific behaviour then that behaviour shoud be made final preventing from overriding and not declare the entire class final.
Your thoughts please.

Migrating from Sql Server tables with column name starting with integer

hi,
i'm trying to migrate a database from sqlserver but there are a lot of tables with column names starting with integer ex: *8420_SubsStatusPolicy*
i want to make an offline migration so when i create the scripts these column are created with the same name.
can we create rules, so when a column like this is going to be migrated, to append a character in front of it?
when i use Copy to Oracle option it renames it by default to A8420_SubsStatusPolicy
Edited by: user8999602 on Apr 20, 2012 1:05 PM

Hi,
Oracle doesn't allow object names to start with an integer. I'll check to see what happens during a migration about changing names as I haven't come across this before.

Mike

Migrate from Standard 2003 domain with seperate Exchange 2003 to SBS 2011 - possible? how-to?

Hi there,
I am currently planning on replacing two servers (one server 2003 standard (DC) and one server 2003 standard with exchange 2003) with a single machine running SBS 2011.
I already did several migrations SBS 2003 to SBS 2011, SBS 2008 to SBS 2011 - and I am wondering if the same can be done from 2003 Standard with separate exchange server 2003 to a single SBS 2011. Technically I can see no reason why this shouldn't work -
but so far I have been unsuccessful in finding guidelines or at least some success-stories from other users.
Did anyone do something like that? Any caveats I have to be aware of? Or is it supposed to be flawless as the SBS to SBS migrations I did so far?

Hi,
From the problem description, I understand that you would like to migrate Exchange server 2003 on Windows Server 2003 to SBS 2011.
At first, I would like to clarify one thing. Microsoft doesn’t have the official documentation towards this scenario. And Microsoft doesn’t
recommend dealing with that.
I noticed that there are two servers in your organization. One is Windows server 2003 for DC; the other one is Exchange server 2003. So it can’t
be the same as the documentation (Migrate to Windows Small Business Server 2011 Standard from Windows Small Business Server
2003).
I got your key point that you would like to know the detailed procedures (HOW TO). I suggest that you could visit the
SBSmigration.com to get further information you need. Since it’s not the Microsoft official method,
please do the test before your put it into your production environment.
