ABAP and J2EE-Stacks in SAP WEB AS

Hi,
I have two questions about the technical architecture of SAP WebAS, particularly about the ABAP- and J2EE-Server.
Can someone recommend detailed papers/guides (besides help.sap.com)describing:
1) the management of processes and resources in two parts (ABAP and Java)
and
2) The communication mechanisms between J2EE- and ABAP-server.
What are the problems with JCo?
Is there other possibilities to communicate between 2EE- and ABAP-server.(besides JCO), what is the performance in this case compares with JCO?
Thank you!
Peter Hneke

Hi,
Step step description here is not possible.
It always advisable to go to service.sap.com/instguides.
slow and steady wins the race.
good luck.
It's advisable to have quad processor with atleast 8GB ram.
If it's a nw04s then at a shot you can select AS ABAP. JAVA, EP, PI(XI) and proceed.
hope this helps you.

Authorization objects in web dynpro ABAP and SU24 transaction

Hi,
I have created a new authorization object to check a storage location for certain activities. I have added the authorization object in a specific web dynpro ABAP and I have created a new role in PFCG for my web dynpro ABAP.
The organization level for storage location is not recognized in PFCG. Someone told me I have to maintain my authorization object in SU24 as it is done for transaction.
I wanted to maintain my web dynpro in SU24 but I found no way to do that.
It seems that we can maintain authorization for TADIR service and in those services there is R3TR WDYA but when I use the search help for OBJ_NAME I don't find may web dynpro ABAP. I suppose I have to create a TADIR service for my web dynpro ABAP or something like that but I don't know how to do ?
Does anybody know how to deal with specific authorization in web dynpro ABAP and t ohave the organizational level recognized in PFCG.
Thanks for your help,
Emmanuel

Hi,
Please RUN the function module as "AUTH_TRACE_WRITE_USOBHASH" with following parameter
R3TR
"custom webdynpro application"
SERVICE TYPE and Service can be kept blank
after this try SU24 it will be available in SU24 list.
Thanks & regards

Diff in web dynpro abap and Java

Hi Friends,
   I am new to web dynpro ABAP and Java.
     1) Please give me idea about about these two
      2) In which Scenarios these are helpfull
     3) From which version   onwards these are existing
Thanks for your help.
Thanks,
Asha

Hi Ravi,
The following are basic differences between ABAP and JAVA WD.
1. ABAP WD can be developed in ABAP Workbench thru transaction SE80 whereas Java WD needs SAP NetWeaver Developer Studio.
2. Since ABAP WD is a part of the ABAP Workbench, it has direct access to ABAP dictionary. Hence access is faster.
3. In order to develop on ABAP WD, you will need basic knowledge of ABAP objects, whereas in Java WD, dev is using Java

DB-API in ABAP and J2EE

Hello!
I have two questions regarding the communication mechanisms between ABAP- and J2EE-Stack.
1)Is Jco the only one solution to communicate between ABAP- and J2EE, or exist other possibilities (if Yes, is there some comparison papers: performance, advantages/disadvantages).
2) Which similarities/differences are in the DB-communication in both Server? (e.g. each Workprocess in ABAP/Serverprocess in J2EE<--> DB-Process)
Which DB-API is used in both stacks?
Thank You!
Regards

Hi, Peter!
For both languages - ABAP and Java - SAP offers a Dictionary (for definition of database objects) and Open SQL (for database independency), you may also in both languages embed static SQL scripts into you code (via SQL/J in Java).
For Java there' s the Persistence-Framework offering three support levels, Vendor-JDBC, Native and Open SQL the last one guaranteeing the maximum support. You may in Java access data - via JDBC and SQLJ - in a relational or - via EJB/CMP or JDO - in a object-relational way.
Performance-Features like Table-Buffering exist also in both stacks.
Please have a look at <a href="http://help.sap.com/saphelp_nw2004s/helpdata/de/61/fdbc3d16f39e33e10000000a11405a/frameset.htm">Developing Java Persistence</a> for more information regarding the Java-Part.

Decouple the ABAP and J2EE

Hi All,
I was installed the Netweaver server on windows 2003 server over sqlserver database. The jlaunch and sqlserver process is taking too much memory.
I would like to decouple the ABAP and J2EE server ......how can i approch this. Is there any way to reduce the memory usage of sqlserver and jlaunch process....?
Is there any solution to that problem...please let me know.
Thanks & Regards,
Sridhar M.

I would like to decouple the ABAP and J2EE server
I didnt understand the term decouple over here for ABAP and JAVA instance. But however, if you dont want the JAVA instance to start along with ABAP, you can control it through the profile parameter rdisp/j2ee_start.
More info:

Web Dynpro ABAP and Case Management

Hi there!
How do i implement a case management subcomponent in web dynpro ABAP?
For classic GUI this is done by implementing the interface IF_SCMG_SUBCOMPONENT or by making CL_SCMG_SUBCOMPONENT_SP the superclass of your own class. But i don't know how this is going to work for wda.
Thanks a lot

Hi Karim,
Yes there is - try the function modules
HRWPC_OADP_DELETE_TGTOBJCACHE
HRWPC_OADP_DELETE_SRCHOBJCACHE
HRWPC_OADP_DELETE_NAVOBJCACHE
HRWPC_OADP_DELETE_DATAVWCACHE
Depending on what you want to refresh - you may not need to call all of them.
if you do this in the init of your app you can be sure to get the latest versions of the structure.
However, be aware that it can take some time for the OADP to read and build these structures - which is why they were cached in the first place! Depending on what you are trying to achieve, you may be better off (from a response time) building your own code.
Hope this helps,
Chris

Have anyone done porting COBOL application to ABAP and J2EE?

Hi all,
(Hi Stefan Klensch: this is my next question:-))
I am a newby in the SAP world and just walking around a few days.
The problem I am facing is porting a large COBOL application to ABAP and mapping the generic business functions of that COBOL application according to the business process involved to adequate functions of the CRM- and HRM suites.
AND
The required customization of strategic business domain knowledge must be implemented in the J2EE domain e.g. for portability reasons. So at the end of the day I will have a SAP J2EE application and the above mentioned SAP ABAP solutions.
Yes, I want to use UML for the analysis and design (e.g. clas/component diagrams) because UML diagrams give me an better architectural (and maintainable) view and design of the system.
I am looking for the rare developer(s) who did such a kind of challenging job before. I hope they can give me hints and information the way they handled and solved such a problem. E.g. roadmap, methods, tooling, etc.
Many thanks in advance.
Thiel Chang

etresoft,
I downloaded the sample code for EvenBetterAuthorizationSample project and I changed the userid for the Developer id application as suggested by Apple below and built it, but still when I run the app and click on the "Read License" button or other buttons I get the error NSCocoaErrorDomain 4099 connectionInvalid
Before you build you need to adjust some Info.plist values to match your Developer ID. Specifically, search the entire sample code directory hierarchy for all instances of "SKMME9E2Y8" and replace it with the User ID value from your "Developer ID Application" certificate.
As far as I can tell, the sample app is properly code signed with our certificate along with the helper tool
Is there something else I need to change to get this sample app working so I can understand this better

Synchronising ABAP and J2EE accounts

Hi All
We are currently having a small issue with our ABAP and Java stacks on BI, basically when we create a user in the ABAP stack it does not appear in the JAVA Engine unless we reboot the whole thing.
Is there something that needs to be configured - e.g. JCo Connector or RFC
And can the by synchronised immediately or is there a job that needs to run?
Thanks in Advance
Phil
