Using JSF in a Portal

I've got an application developed in JSF, and would like to include it into the SAS Information Delivery Portal(Which many of you have probably never heard of...) but here is the issue. When running an what is called external portlet we only render fragments of the html and not the entire html page. But now the context is for the portal, so certain assets like images and css are not picked up by the application. Also since JSF only puts a relative action in the form (action="MyApp/MyJSFPage.faces;jsessionid=GsMqF9JRgfr.....) so now the form post doesn't post back to my app.
Any suggestions? I'm new to portals.
Summary, need to have assests paths fully qualified along with form actions.

what is the stack trace of the exception?

Oracle portal using JSF, JSP, Struts framework

Hi ,
Can anyone tell me how to build an oracle portal using JSF,Jsp and Struts Framework.
Also please provide any manual or documentation for developing oracle portal.
Thanks in Advance,
Raghav

At present, i think the best thing to do is to look at the example provided with the struts-faces integration taglib. I don't know any documentation about it.

Portal Development using JSF & Struts

Can some one explain about the feasibility of developing portals using JSF and Struts? What are the advantages and disadvantages of doing so? Is it a right decision to develop portal servers using these?

Yes I am familiar with all those links. Let me break down scenario and ask specific questions.
Server version: Netweaver 7.0 (2004s) SP18
1. Created External Library DC (i.e. ebuslib)
         - added 3rd party JARS (e.g. hibernate, Spring)
         - created two public parts - one for compilation, one for assembly (deploy)
         - activated activity
2. Create J2EE Server Component - Library DC (i.e. ebuslib2)
          - added "ebuslib" assembly PP as Used DC (build only)
3. Built "ebuslib2"
          - can see jars in the resulting sda file.
          - activated activity
          - confirmed on J2EE engine deployed library containing the jars.
Scenarios
A. EP Project DC
           - needs access to 3rd party jars
           - QUESTION: What do I need to reference? The External Library DC or the J2EE Server Component Library DC?
                         - I read that you should reference the J2EE Server Component BUT the jars are not available in the PP of that DC.
                         - One developer one talked to referenced the compilation PP of the External Library DC (i.e. "ebuslib").
                                 - this seemed to work but then I wondered how the project finds the JAR at runtime?
QUESTION: Does SAP load all the classes that have been deployed via the J2EE Server Component Library DC method and hence those JARs are globally available at runtime hence no need to reference them during development except for compilation? What if > 1 J2EE library contain the same jar or same API but different versions (e.g. Hibernate 2 vs 3).
Thanks for any clarifications. I want to understand the underlying technology and how it works. I have seen alot of information out there but some of it is confusing and conflicting.

Portlets developed in JDev 10.1.2 and using JSF

Hi,
Is it possible in JDeveloper 10.1.2 to create a portlet that uses the standard JSF libraries (not using Oracle ADF Faces libraries etc...), which can then be consumed by Oracle Portal 10.1.4, without having to use the JSF-Portlet bridge that is part of the WebCentre Suite ?
The reason I ask is that I would like to develop portlets in JDeveloper 10.1.2 using JSF but I don't have a WebCentre Suite license. I don't think there is much point in moving to JDeveloper 10.1.3.2 to develop my portlets as I would still be in the same situation, I would ultimately need a WebCentre Suite license in order for them to be consumed by Oracle Portal 10.1.4, or am I missing something ?
Thanks.

The JSF Portlet Bridge is available separately.

Authenticating user in JSF from PHP portal (Joomla)

Hi there!
Here, where I work, there's a portal in php (Joomla) where all users gets authenticated.
I made an application using jsf and the protection to some pages, from anonymous access, is done by JSF Filters, but the users needs to login twice (Joomla and JSF).
I need to avoid the redundant authentication.
I found this solution: http://www.nuwanbando.com/?p=72, but modifying Joomla pages is not an option for me.
Please, someone can comment about some possible solutions that I can use?
Thank you in advance!
Flávio Henrique

There are many possible solutions, but you would need to figure out how to make the JSF pages secure by disabling authentication for the JSF pages. You could do this with some template that only displays the pages if something else is provided like some parameter passed to the JSF side, but that gets risky. Really what you are needing is single sign on feature that works between technologies. I would imagine you would really need some kind of federated authentication server that both PHP and JSF talk to and that both would share a single session id of some type. - Ponderator

HOW TO SET UP PARTNER APPLICATION TO USE SSO OUTSIDE OF PORTAL

If anyone knows how Portal switches context to run as the db user mapped to the lightweight schema and how it knows the db schema password please let me know.
Should you have any queries please do not hesitate to contact me on 07775 896738.
From document Oracle Portal Security Overview on PortalStudio.oracle.com:
In Single Sign On mode (EnableSSO=Yes in the DAD), mod_plsql determines the name of the light-weight user and mapped database schema by calling
WPG_SESSION_PRIVATE.GET_LW_USER and WPG_SESSION_PRIVATE.GET_DB_USER respectively.
** These calls are done using the Portal Schema (PORTAL30) and Portal schema password **
mod_plsql then executes the procedure in the requested URL by using the N-Tier Authentication feature to connect to the database as the user returned from
WPG_SESSION_PRIVATE.GET_DB_USER. ..... Note that N-Tier Authentication requires all schemas to be used for Portal user mappings to be granted 'connect
through' privleges to the Portal schema (PORTAL30).
The WWCTX packages are also used.
So this is how it works with standard Portal
- the document states that the WPG_SESSION_PRIVATE package is only accessible to the Portal schema
- but I checked and it is also available to PORTAL30_SSO
SQL> desc WPG_SESSION_PRIVATE
PROCEDURE CREATE_SESSION
Argument Name Type In/Out Default?
P_COOKIE_NAME VARCHAR2 IN
FUNCTION GET_DB_USER RETURNS VARCHAR2
FUNCTION GET_LW_USER RETURNS VARCHAR2
PROCEDURE GET_SESSION_INFO
Argument Name Type In/Out Default?
NUM_PARAMS NUMBER OUT
PARAM_NAMES TABLE OF VARCHAR2(32000) OUT
PARAM_VALUES TABLE OF VARCHAR2(32000) OUT
PROCEDURE RESET_SESSION
Argument Name Type In/Out Default?
P_COOKIE_NAME VARCHAR2 IN
In my case only the Login Server (PORTAL30_SSO) is going to be used/installed
- the SAMPLE_SSO_PAPP application will only work if the DAD used to access is it set to use Basic authentication, i.e. the actual integration with the Login Server
is done in the sample application code calls, stored in the database
- when a DAD has enableSSO=yes it automatically accesses Portal (PORTAL30) packages to implement N-Tier authentication
I'm currently testing:
1. Configuring the SAMPLE_SSO_PAPP sample as documented with a DAD with Basic authentication
2. Amending the ssoapp procedure to set context to another (db) user on successful authentication:
wwctx_api.set_context (
p_user_name => 'SCOTT',
p_password => 'TIGER' );
3. If this works then set_context with get_lw_user instead
I have now amended the ssoapp procedure as follows to print out
1. The userid entered when the login box is presented
2. The Database user which the Portal Lightweight user is mapped to
3. The Lightweight user Portal has used for authentication
Amendments to papp.pkb:
(ssoapp procedure, declare db_user_info and lw_user_info as VARCHAR2 in declare section)
htp.p('Congratulations! It is working!<br>');
db_user_info := wwctx_api.get_db_user;
lw_user_info := wwctx_api.get_user;
htp.p('User Information:' || l_user_info || '<br>');
htp.p('DB User Information:' || db_user_info || '<br>');
htp.p('LW User Information:' || lw_user_info || '<br>');
The following shows the interesting results from my testing:
- if the user owning the sample_sso_papp package is PORTAL30_SSO then the call to wwctx_api.get_db_user succeeds
- if the user owning the sample_sso_papp package is a non-portal schema e.g. SSOAPP below the call to wwctx_api.get_db_user generates a User Defined exception
Steps to test:
Created new schema SSOAPP on the database
- edited it in Portal and checked the use this schema for Portal users checkbox
- created new Lightweight user SSO_LW in Portal, mapped it to SSOAPP schema
- created new Lightweight user SSO_SCOTT in Portal, mapped to SCOTT schema
- loadjava -user ssoapp/ssoapp@portal30 SSOHash.class
- sqlplus portal30/portal30@portal30
@provsyns ssoapp
- sqlplus ssoapp/ssoapp@portal30
@loadsdk.sql
@loadpapp.sql
Created DAD with basic authentication SAMPLE_SSO_PAPP
- username: ssoapp
- default home page: sample_sso_papp.ssoapp
Registered the Sample SSO Partner Application with the Login Server and ran regapp.sql
Commented out the calls to get_db_user in papp.pkb to avoid exception
- called http://<server>/pls/sample_sso_papp
- logged on as SSO_LW/sso_lw
- got output:
Congratulations! It is working!
User Information: SSO_LW
LW User Information: PUBLIC
So the Portal lightweight user is not returned as SSO_LW
if anyone knows why the Lightweight User in my test is returned as PUBLIC not SSO_LW

Using JSF and Struts

I am a bit of a newbie in terms of UI applications on the JEE platform, so I apologize up front if this question seems silly. I was wondering if someone could comment on the approach below. Is this something that's possible or am I barking up the wrong tree?
We have a vendor application that is written using Struts. We want to add a section of our own pages to this application, but we would rather use a more strategic approach in our pages, so we would like to use JSF for those.
The original web.xml file in the vendor app uses a dtd of version 2.3 as shown below:
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
When I use JSF, I use a DTD version of 2.5 as shown here:
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
The problem is that when I use version 2.3, the elements needed to support JSF are invalid. When I use 2.5, the elements needed to support struts are invalid.
Could someone comment in that, if you had this vendor app and you needed to add your own pages, is it not possible to use JSF in this scenario or if you can, what is the best approach to resolving this issue?
Thank you in advance

First make sure that your application server supports Servlet API 2.5. Whether the desired Servlet API version is supported or not solely depends on the application server implementation and version used. For example Tomcat 5.5 is a Servlet API 2.4 implementation which only supports the API versions up to with 2.4. If you want to use Servlet API 2.5, then you obviously need a Servlet API 2.5 implementation, for example Tomcat 6.0.
Consult the website and/or documentation of the application server in question.

Can one create a floating window using JSF?

I was recently shown the interface for GMail. I don't have a GMail account, but one of the things I was asked to investigate was whether or not we can create the sort of floating window that appears on the GMail interface when one positions the mouse pointer over a cell on the grid showing the email messgaes. We have a grid on our JSF page, that shows specific data for items we're supporting, and it would be useful if we could have something like a mouseover event handler for each table row, and in that event handler show a window with a graphic specific to the data in that row, and the chart would move with the mouse pointer, perhaps changing the graphic if the mouse pointer is moved over a different row in the data table.
Can we do this using JSF? If not, what alternative can you suggest that would provide a reasonable facsimile to this kind of user friendly feature?
Thanks
Ted

"Core JavaServer Faces" Second Edition, by David Geary and Cay Horstmann, copyr 2007 - ISBN: 0-13-173886-0 - (it put me back USD $50, but well worth it). Page 644 gives two examples of how to generate a pop-up window. They give two examples because of problems that can arise when you transfer data between the main window and the pop-up. I do not want to violate copyright and there are ten pages of text devoted to this topic, so I'll just present some tickler code - if you cannot afford the book, maybe you can google on some terms. Sorry, I feel this is as far as I can go on this, I hope this helps some!
The first example uses a JavaScript call:
popup = window.open(url, name, features);
popup.focus();
where 'features' is a string like "height=300,width=200,toolbar=no,menubar=no"
The second example creates the pop-up form using a hidden field like this:
<h:form id="hidden" target="popup">
<h:inputHidden id="country" value="#{bb.country}"/>
<h:commandlink id="go" action="showStates"/>
</h:form>

Advantages of using XI in Vendor portal (webdynpro) development

Hi,
I will be greatful if anyone provide the advantages/disadvantages of using XI in vendor portal development. I need this information for my presentation to my client. I need it in urgent. Thanks in advance.

ITS will be much handy when you want to display standard SAP transaction in portal/browser frontend.
with ITS , you can expose the transaction to web with zero coding, but had to live with the limitation of not being able to change the look and feel much.
whereas if youdecide to program the entire transaction yourself for the web, it will be really time consuming and sometime may not be able to provide the same look and feel and functionality which sap win/web gui offers.

How to send a https request using jsf

hi
Can anybody tell a sample how to send a https request using JSF ...
thanks

Prefix the request URI with the https protocol.
The answer is too easy and straightforward that I guess that you mean something else. If you just want to know how to configure an SSL environment for your own webapplication, refer to the Java EE tutorial chapter 28: http://java.sun.com/javaee/5/docs/tutorial/doc/

Issues in using JSF UI:Tree tag

Hi,
I am trying to work with Tree Structure using JSF UI tags. In Studio Creator i just created a JSP page and designed a Tree with two nodes under it. This is what i have in the body of my jsp.

Any suggestion to solve this issue would be greatly helpful.

Now with Unified EL - JSTL and JSF tags are supposed to work on one page.
If you want to use Unified EL you need
1) A container that is built on Servlet 2.5 / JSP 2.1 , and example of such a container is Tomcat 6.x
2) Probably need to upgrade to JSTL 1.2 , and JSF 1.2
3) If you're upgrading the container to Servlet 2.5 then web.xml should conform to Servlet 2.5 version.
4) Use correct taglib URIs for JSTL 1.2 and JSF 1.2

Thanks for the link, I did search a little while before making the original post. I guess I wasn't searching for the right thing though.
The method I found listed in here seems to work in IE but not Firefox. It could just be a caching issue though I'm not real familiar with firefox and don't really know how to get it to forget that it's been to a page already.
I also updated the link listed above to ask about any changes in the last upgrade related to this.
This was related to caching in firefox and it worked fine after I logged out of my apex.oracle.com account and cleared the personal cache in firefox and then started over.

Using JDO in a portal component.

Hi!
I've tried using JDO in a portal component (DynPage), but it just won't work for me (WAS 6.40).
What I've tried is this:
- Looking up a PersistenceManagerFactory using the name "java:comp/env/jdo/defaultPMF"
This does not work ... I get a NameNotFoundException: Path to object does not exist at java:comp, the whole lookup name is java:comp/env/jdo/defaultPMF
- After reading this forum I tried with the name "deployedAdapters/jdo/defaultPMF/shareable/jdo/defaultPMF" although this is probably not the correct way
This did return a PersistenceManagerFactory object, however I wasn't able to cast to the PersistenceManagerFactory interface that I had. It must have been different versions of the interface - I tried downloading the jdo.jar from Sun and compiling the portal component against that, but still the ClassCastException occured. I used the reflection API to determine that the object returned did in fact implement the interface named javax.jdo.PersistenceManagerFactory. I even tried using the jdo.jar libraries from the server, but to no luck.
So ... my question is: Is JDO not available from a portal component? Must I develop a J2EE application to make it work? If so, I'd rather use Hibernate in my portal components, but it seems stupid when JDO is available?
Thanks,
Thomas

Hi Thomas,
In order to be able to use JDO in a Portal component, you have to add a Private Sharing Reference to the application sap.com/com.sap.jdo. This is a standard application provided with the SAP WebAS Java installation.
For more info on how to do that, please refer to <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/ep/g-i/how%20to%20access%20an%20ejb%20from%20a%20portal%20component.mht">this</a> tutorial -> Accessing the EJB -> New Portal Component -> scroll to the section "Add PrivateSharingReference".
Hope that helps!
Vladimir
