NLS compatibility of portal components

Nice to be back to discussion forums after a long time :)
What are the best practices for building NLS compatible portal components such as Forms, Reports, LOVs. wwnls_api seems to be useful only for custom portlets and dynamic pages. However for Forms created based on tables/views, the field names are all static strings and we don't have anyway of manipulating these strings using wwnls_api.get_string method.
One crude strategy is to maintain a duplicate copy of a component for every language which would not only increase the extensibility but also consumes lot of development time. Can someone suggest a better way?
I went through the following article - but it does not address Forms, Reports etc., translation.

Thanks in advance,
Amjad.

Hi Amjad,
Good to see you.
I don't think there's an easy way to achieve this. Try to post your question in the Portal Applications forum.

Passing Values Between to portal components

Hi All,
Im having 2 portal components in my UI ,in the 1st component user has to select data from dropdownkey and inbox and i need to carry these values and display in 2nd portal component,also user has to select somemore details from the second portal component..,based on all his inputs i need to create a new data in r3 system.
Any codesamples,articles..??
regards,
Vinoth

Hi,
This is possible and very easy to implement.
Since version 1 patch 3 of the PDK.NET was released, embedded .NET iViews on the same page are processed together. So you could actually access one portal component from another.
One of the new features of version 2.0 was creating server side events between iViews on the same page at design time Take a look at the following <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/dotnet/pdk%20for%20.net/developer's%20Guide%20PDK%202.0%20for%20.NET/Programming%20with%20PDK%20for%20.NET/Designing%20Portal%20Pages/PPD_Workflow.htm">link</a> .

Another option is to implement client side events using the EPCM, <a href="https://media.sdn.sap.com/html/submitted_docs/dotnet/How%20to/Portal%20Client-Side%20Eventing.htm">here</a>is the link to that how to.

Errors Installing Portal Components using 9iAS Enterprise on 8.1.7 SE

We are getting an error installing the Portal Components using
9iAS Enterprise on a 8.1.7 SE database. The log indicates that
the error is:
ORA-00439: feature not enabled: Function-based indexes
Errors encountered in the Install process. Installation Aborted.
While I know that Function-based indexes are not supported in SE
this should not prevent the installation of Portal.
Does anyone have any suggestions?
Thx, Paul

Its also working in our case where we have used 8.1.7 Enterprise Edition. We installed 9iAS 1.0.2.0 on NT. So if you have any issues regarding this then let me know.

Advanced Development Techniques for Oracle Portal Components

Hello friends,
I have the following problem. I have a report and a form (on a
view) in the same page, and when I select an item of the report
the form is refreshed with the values associated to the selected
item. The problem is that it makes it with delay, the first
selection doesn't show anything and the remaining sample the
data of the previous selection.
This application has been developed as Ken Atkins explains in
its document "Advanced Development Techniques for Oracle Portal
Components."
Oracle Portal Version: 3.0.9.8.0
Thanks in advance.
This is my code:
-- REPORT --
SELECT '<A HREF="http://mipc/portal30/
ALFONSO.refrescar_contenido?
p_variable=nombre_preferencia&p_variable_valor='||nombre_preferen
cia||'&p_pagina=61">'||Preferencias||'</A>' nombre_link
FROM ALFONSO.PREFERENCIAS
-- PROCEDURE TO REFRESH THE PAGE --
CREATE OR REPLACE PROCEDURE refrescar_contenido(p_varible IN
VARCHAR2,
 p_variable_valor IN varchar2,p_pagina IN
VARCHAR2) IS
v_Sesion portal30.wwsto_api_session;
BEGIN
v_Sesion := portal30.wwsto_api_session.load_session
('CONTEXT','SESS_EMP');
v_Sesion.set_attribute(p_varible, p_variable_valor);
v_Sesion.save_session;
owa_util.redirect_url('http://mipc/servlet/page?
pageid='||ppagina||chr(38)||'_dad=portal30'||chr(38)
||'_schema=PORTAL30'||chr(38)||'_mode=3');
END;
-- FORM --
-- ... BEFORE DISPLAYING THE PAGE
alfonso.consulta_preferencia(p_session);
-- PROCEDURE consulta_preferencia --
CREATE OR REPLACE PROCEDURE consulta_preferencia(p_session in
out PORTAL30.wwa_api_module_session) IS
v_RowID VARCHAR2(100);
v_Session portal30.wwsto_api_session;
v_nombre VARCHAR2(40);
BEGIN
v_Session := portal30.wwsto_api_session.load_session
('CONTEXT','SESS_EMP');
v_nombre := v_Session.get_attribute_as_varchar2
('nombre_preferencia');
IF v_nombre IS NOT NULL THEN
BEGIN
 SELECT rowidtochar(rowid) INTO v_RowID
 FROM ALFONSO.VISTAPREFERENCIAS
 WHERE nombre_preferencia = v_nombre;
-- VISTAPREFERENCIAS it is the view in which the form is
based.
END;
-- Tell the component that the query is coming from a link,
and that the rowid
-- is being used to query the correct context record.
p_session.set_value (p_block_name=>'DEFAULT',
p_attribute_name=>'_CALLED_FROM_LINK'
 ,p_value=>'ROWID');
-- Pass the rowid of the context record to query.
p_session.set_value (p_block_name=>'DEFAULT',
p_attribute_name=> '_ROWID'
 ,p_value=> v_RowID);
-- Now do the actual query, using the query button
processing in the target module
portal30.wwa_api_module_event.do_event
('DEFAULT','QUERY_TOP',1,'ON_CLICK',True,'',p_session);
-- Save the session information, which includes the
p_session.save_session;
END IF;
END;
/

You can make the report with a procedure from which you may call to a form by means of a link. It is a possibility, no??
It is better a example:
TABLE A
campo1 VARCHAR2 (20)
campo2 VARCHAR2 (20)
CREATE OR REPLACE PROCEDURE REPORT IS
v_cursor NUMBER;
sentencia VARCHAR2(200);
vnumfilas NUMBER;
rowid_pref VARCHAR2(18);
v_campo1 <schemaname>.A.campo1%TYPE;
v_campo2 <schemaname>.A.campo2%TYPE;
BEGIN
 htp.p('<HTML>');
 htp.p('<HEAD>');
 htp.p('</HEAD>');
 htp.p('<BODY>');
 sentencia := 'SELECT rowidtochar(rowid), campo1, campo2 FROM A';
 DBMS_SQL.PARSE(v_cursor,sentencia,DBMS_SQL.V7);
 DBMS_SQL.DEFINE_COLUMN(v_cursor,1,rowid_pref,18);
 DBMS_SQL.DEFINE_COLUMN(v_cursor,2,v_campo1,20);
 DBMS_SQL.DEFINE_COLUMN(v_cursor,3,v_campo2,20);
 vnumfilas := DBMS_SQL.EXECUTE(v_cursor);
 LOOP
 IF DBMS_SQL.FETCH_ROWS(v_cursor)=0 THEN
 EXIT;
 END IF;
 DBMS_SQL.COLUMN_VALUE(v_cursor,1,rowid_pref);
 DBMS_SQL.COLUMN_VALUE(v_cursor,2,v_campo1);
 DBMS_SQL.COLUMN_VALUE(v_cursor,2,campo2);
 v_link := '<A href="PORTAL30.wwa_app_module.link?p_arg_names=_moduleid'||chr(38)||'p_arg_values=<form's moduleid>'||chr(38)||'p_arg_names=_rowid'||chr(38)||'p_arg_values='||rowid_pref||chr(34)||'>'||campo1||'</A> '||campo2||' ';
 htp.p(v_link);
 END LOOP;
 htp.p('</BODY>');
 htp.p('</HTML>');
END;
the form has to be based on the table A.
I dont know if this example has errors, but have you the idea??
I hope it helps you out.

To develop portal components

Hi Friends,
Recently i got access to SAP Enterprise Portal 6.0 server of our parent company in US. Locally i have developed some portal components using Tomcat_PDK and Eclipse.
How to deploy these portal components into the SAP EP?.
Can anybody please explain me the functionality of the tabs available in SAP EP Server homepage?.
Thanks.
Regards,
Tamilarasan.

Hi Tamilarasan,
the first difference between EP5 & EP6 for developers is that there is no PDK beneath th EP. The "PDK" for EP6 is a business package (a role with some content) to import into EP6. From there, you can upload components (PAR files), delete them etc., and you have the doc's that you know from PDK 5.0.
There is also a different Eclipse plugin!
Portal components for EP5 and EP6 differ in many points, for example there is a xml deployment descriptor in EP6 where in EP5 you had the profile property files.
Also some APIs have changed of course.
But you can import EP5 par files into Eclipse with the EP6 plugin, so this would be a starting point.
Hope it helps

Pro/cons for dev. environments for Enterprise Portal components

Hi
I am looking for some positives and some negatives that should be considered when a client needs to decide on which development environment to use for Portal development. I am aware of three products, Visual Composer, Web Dynpro and NW Developer Studio.
Is there anyone who can briefly try to explain the positives and negatives with each?
Any feedback is greatly appreciated!
Kind Regards,
Thomas Kjelsrud

Hi Thomas,
first, welcome on SDN!
Then about your question:
The standard IDE for any kind of portal components / applications is the NetWeaver Developer Studio (NWDS). By this, you can develop different things (EJBs etc pp), but also portal specific projects (in the end: PAR files, based on AsbtractPortalComponent, DynPages or JSPDynPages) as well es WebDynpro applications. The latter are able to run standalone (ie not driven by EP, but by WAS J2EE 6.40), but there is also a tight integration into the portal environment.
If this is understood, you know that the question "NWDS or WebDynpro" does not make sense, for WebDynpro is developed through NWDS.
A first overview about this issue so far is https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/documents/a1-8-4/exploring java programming models with sap netweaver developer studio.pdf
In that PDF, also the relationship of the tool NWDS and the programming model of WebDynpro is given (even if the term "relationship" may be misguiding, it's more that these two things are to be seen in a comparison, for they use different techniques, are meant for different aims etc.)
The VC is a totaly visual tool to build "applications" for EP mainly based on access to R/3 as backend system, for example. So it's focus is on building UIs which access backend information. That for sure is important for backend integration into EP, but the term "application" does not really fit.
For VC see https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/documents/a1-8-4/developing code-free business applications using visual composer - beginner.abst and https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/documents/a1-8-4/visual composer - a model-driven development tool for enterprise portal iviews.pdf as an introduction.
Hope it helps

Determine Isolation Mode for directly called Portal Components

Hallo there,
I created a custom Navigation, that calls a portal component directly (without building pages and iViews in the PCD).
My portal component just reads the content of a given Resource from the KM repoitory and renders it to the servlet response.
To Launch the component I give the LaunchURL "/servlet/prt/portal/prtroot/MyApplication.MyComponent?RID=/myrep/conents/content.html" to the navigation node. When calling my custom navigation the component is called and the content of the given resource is rendered correctly.
But there is one thing I want to change: the content is always rendered into a isolated iFrame, which is isolation Level URL. Now im wondering how I can force the component to be rendered as EMBEDDED into the view.
What i tried so far is to add the following property to the portalapp.xml (component-profile), but this didn't work:
<property name="com.sap.portal.reserved.iview.IsolationMode" value="EMBEDDED"/>
Can anybody give me a hint how to solve this problem?
Thank you for your answer,
Frank

Hi Priya,
Yes. Putting different portal components in a page definitely means a page conatining different iviews.

How to search for the list of portal components that use a certain LOV?

hi,
does anyone know how to search for all of those portal components which use a certain other component?
let's make it specific. how can i know which of the portal components (portal reports and forms, content folders, etc) are using any certain LOV?
will really appreciate any hints.

CRM Application Server Java and Portal components on same Java stack

Hi Team,
We are currently performing solution design and want some information on CRM install.
Want to know if there is any restriction for installing CRM Application Server Java and Portal components on same Java stack(With same SID). Also want to know if SAP WEB UIF 7.0 can work similar to that of Portal for CRM applications?
Any information around this would be appreciated.
Thanks

Do You have any servlets or filters defined using annotations? Maybe one of these servlets/filters catches the '/login' request first. I have very similar solution and it works fine. Also, how do You check that the servlet under '/login' url pattern isn't invoked?

Portal Components and SSL

I have my solaris 3.0.8 portal environment accessible via https and http connections by using Apache virtual hosts. Ideally I'd like to be able to force an https protocol when users access some sensitive application components. Is this possible? If not, does anyone have any suggestions for a workaround that could produce the same results?

Hi Vali
PORTAL COMPONENT
from user point of view,a component that can be displayed into a portal page.from an apllication development perspective,a plug able to component designed to be executed into a portal environment
PORTAL SERVICE
A component offering a globally accessible function in the portal.the portal runtime development model offeres a way to implement a clear separation between a Service
API and its implementation
A Portal Application contain two types of resources :
1)Web Resources
 - Accessible via http / https requests to a web server
 - All files Not unber WEb-INF
2)Non-Web Resources
 - Not accessible via an http / https request
 - All files under WEB-INF
A portal Application can contain:
a) Several portal components and several portal services.Using several sections in DD these components and services are defined
b)only ONE Portal Component
c) only ONE Portal Service
All portal services of a portal application are declared in service sections within the services section

Thanks... I will am closing this but in case you have some material for me to review on the following, I will appreciate:
You wrote
1.
"You can convert standard cube to real time even if it already has data without loss this data by using program SAP_CONVERT_NORMAL_TRANS (via SE38)."
--on executing se38, and entering this program, it opened the code and I was stuck not knowing what to do.
I can make simply ABAP modification but did not know how to copy data from one cube to the other using this program
2.
"Via copying data from any other cube using IP functionality (copy function or FOX formula)."
The RSINPT was simple but I had no clue on this suggestion, any additional info specifically on this will be helpful.
In general, in real environment with large amoun of data, which method do you use?
Thanks
