Customising CATS Webdynpro or PDK or BSP

Hi SDN Gurus,
Currently we've have configured CATS application in EP using ITS.
Because of performance related issues , we are planning to develop the application based on BSP/PDK/Webdynpro.
As I am new to BSP/Webdynpro/PDK your thoughts on this will be very much useful to me.Please guide me which option is better performance wise for CATS.Request you to provide any useful link/ info in this regard
Thanks in advance.

Hi Sujesh,
To achieve this create Development component.
In your component controller of WebDynpro Component add your database related code.like getting connection,registering connection etc.
This approach is much like all java applications connecting with oracle.
You can use JDBC connector service. Here you can configure Java based thin drivers to connect to Oracle Database. Advanatages of doing this are you can configure several connection paramaters and also do a rough monitoring of the connection usage.
For connection u can use this code:
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@Oracle_server_ip:Oracle port:SID of the Database","user_name","password");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("your query");

WebDynpro or PDK

Hi,
I have a requirement where customer wants to develop web applications in Enterprise portal. The customer doesn't have a SAP Backend system(R/3). The data for the application is going to be in oracle or ms sql server. Which of the approaches will be suitable for developing applications for the portal. Webdynpro for java or PDK(HTMLB,JSPDYNPAGE).
What are the pros and cons of each? Any suggestions?
regards,
Sujesh

Access webdynpro value from PDK

Hi ,
Can i know how to access a value set in webdynpro from PDK java?
Example
from webdynpro--
WDScopeUtil.put(WDScopeType.CLIENTSESSION_SCOPE, "BP_ID", "value");
i would like to access the BP_ID value from PDK java. Can i know what is the method ?
Thanks in advance.
Sujith

Just to keep you guys informed... found its not possible to solve the above issue because of underlying architecture differences.
Hence to track a session / user, better use cookies which is possible both in pdk and webdynpro.

Display a ALV report in EP

Hi,
What is the best way to display an ALV report in the Portal?
I would like the report to be displayed in the GUI of the Portal (meaning, I would like to work with WebDynpro or PDK or any other way such that the GUI will be identical to all the other Portal objects).
Thanks in advance,
Aviad

Hi,
You can actually, as suggested by others, code the PDV_ALV found in the PDK yourself.
All you need is to understand the workflow of the BAPI called "PORTAL_ALV_QUERY_CALL".
This BAPI is configured to get the properties of a query and another BAPI (derived from Z_QUERY_SELECTIONS) which plants additional data in the original query.
For example - If you wish to activate a query called myQuery1 in the user group FI-AP with a variant called TEST between a date range selected by the portal user. The parameters passed to the BAPI are as follows -
"QUERY_NAME=myQuery1"
"QUERY_USERGROUP=FI-AP"
"QUERY_VARIANT=TEST"
"QUERY_CREATE_SELTAB_FM=Z_QUERY_SELECTIONS_1"
"FROM_DATE="
"TO_DATE="
What will happen in the background is that the query myQuery1 from the usergroup FI-AP will be activated using the variant TEST and using the QUERY_CREATE_SELTAB_FM value the date fileds will be assigned to their corresponding fields in the query. After the activation the BAPI will return a table with the result.
Hope it helps,
Aviad

Living La Vida JAVA

After playing with WebDynPro and PDK - finally I have a simple list showing. This simple example has provided me with a good starting point - it is a pity that SAP do not provide such simple examples to allow you to get your head around the concepts.
I used the SAP NetWeaver Developer Studio to produce a version of my example using a WebDynPro and a JSPDynPage (PDK). Deployed to my EP6 server and then created iVews to show then in the appropriate theme.
My thoughts on this now are that both WebDynPro and PDK have merits - both achieve same end result with various affects. WebDynPro is clunky and PDK is not tighly integrated with the Studio (unlike the .NET one).
To use the PDK you need to understand the TAGs and the SAPDesignGuild website helps - but would be better if the Studio presented a graphical interface much like DreamWeaver does.
SAP's direction seems to be with WebDynPro and no longer PDK - wonder if this is truely the case ?. SAP does have a lot of work to do in my opinion to get both products up to scratch from a useability point of view.

Specific Search Without TREX

Dear all,
I've a KM directory that have many files, so I need to filter this by date or a custom attribute, have some possibility to do it without use TREX?
Best regards

Hi,
It is absolutely possible using KM API'S in java webdynpro or PDK.
Simple Logic would be ask user to give some value, get resource (file) from your folder, compare custom property value to user input value.

CRM PCUI or not?

I'm a bit confused about CRM implementation options for using PCUI/BSPs vs "pure" iViews (iViews that don't call PCUI BSP pages).
(by the way, we're planning on implementing CRM 5.0 on EP 6)
Is PCUI/BSP vs iView/no BSPs an architectural decision that I need to make? If so, what are the pros & cons for each option?
Thank you - Matt

Hi Matthew,
we have a CRM implementation based on CRM 4.0 on EP6.0
We are using a combination of BSP pages and "pure" iViews developed in webdynpro calling BAPIs in the CRM system.
for example we are not using factsheet but webdynpro reports. when creating a lead we used a webdynpro with an iView designed for our needs (with instruction to the users what to write in each field) then called BAPI for Lead.create (adding some logic not possible in CRM) and after commit if the users needs to display/change the lead he will navugate to the BSP.
What you should do is define all tasks the user needs and then decide how to develop the iView that supports every task.
BSP are supplied with the CRM system so if your needs are like the standard effort is less in development
(webdynpro ot PDK) you can do more but you need more effort and skills.
from what I saw crm 5.0 has some more BSP applications to support what we developed in webdynpro.
hope this will help you.

Eventing from a PDK appln to a Webdynpro appln ! :(

Hi,
I would like to trigger an event in webdynpro and catch subscribe for it from a PDK application..
(And passing data b/w WD appln and a PDK appln ...)
How can i acheive the same..
WDPortalEventing will work only across WD applns !
Is their any API that suits my requirement !
Any help is appreciated !
Regards
Bharathwaj

Hi Bharath,
You can trigger in WD and catch it in the PDK application.
The following code is for firing an event from webdynpro.
WDPortalEventing.fire ("urn:com.sap.tc.webdynpro.test.portal",
                       "TestEvent",
                       "AParameter");
http://help.sap.com/saphelp_nw04/helpdata/en/5c/1d584289e59041e10000000a1550b0/frameset.htm
It can be captured in portal using EPCF
EPCM.subscribeEvent( "urn:com.sap.tc.webdynpro.test.portal",
         "TestEvent",Function_name);

Calling pdk component in webdynpro

Dear All
is it possible to call a pdk component in webdynpro
Please provide your inputs
Thanks
Karthi D

Karthik,
When you say call a portal component, do you want to navigate away from your webdynpro and call a any portal component?
If yes,It is possible to call portal component. Just create an Iview for the portal component and assign that into portal page.
Call the component using EPCF navigation api inyour web dynpro by passing pcd location of the page.

Passing Value from PDK Java to Webdynpro Java in SAP EP SP18

Dear Experts
Please tell me how to call a webdynpro java ivew form a PDK java application and I need to pass a value to webdynpro form my PDK application.
I am using SP18
Please help me in this issue
Regards
Noel

Noel,
From your PDK aplication you will be providing the WD URL along with the parameter.
Say in your PDK application you redirect to http://portalserver:50000/irj/local/webdynpro/sap.com/test?mypram=1
In WD you fetch this parameter using WDProtocolAdapter class.
Check below links for more information.
