ESS Java iviews
Hi all,
I downloaded ESS business package 4.6c - 4.7 into my EP 6.0 server. One thing I noticed is that except the overview workset ( this workset contains java iviews) all other workset contains pages which links to ITS and basically displaying SAP WEB GUI Screens.
Thus in doubt whether this is the latest business package for ESS or there is another one which has all java iviews instead of SAP WEB GUI views.
Thanks for your time.
Regards,
Shiva.
If your R/3 backend 4.7 or lower then you cannot use the latest ESS BP that is built on webdynpro technology. You are stucked with ITS based services.

ESS Java Iviews vs. SAP GUI for HTML Templates
Hi
We are currently implementing ESS in 4.6c using ITS. We are planning on using the standard delivered ESS services and some custom iviews. We are planning on creating the custom iviews in Java as we can re-use when we upgrade to WAS6.4.
Can we use both Java iviews via a JCo (similar to MSS)and the standard delivered ESS services using ITS ?
Do we need create internet services for the Java iviews that will connect with R/3 thru Jco ( Is it the same as SAP GUI for Java)?Just got of a project where we implemented ESS/MSS on R/3 4.6 using custom iViews in JAVA. Basically we developed one iView template that can be configured using attributes for different services. Each service can be used for ESS and MSS. This decreases frontend development work quit a lot because for most new services you only need to develop RFC's and then configure the iView to use those RFC's and the metadata.
Depending on you timeline you will either need one frontend and one backend resource. You can use one resource if that person knows JAVA and ABAP but it will take longer to finish the service or you can have multiple resources if your timeline requires to have multiple services finished at the same time. You can mail me directly if you have more questions: [email protected] -
'java.lang.NoClassDefFoundError' when displaying ESS webdynpro iviews
Hi,
We are running ECC5 backend & EP6 SP9. I have done the following :
(1) Applied via SDM the XSS components & ESS 60.2 Business Package in EP6
(2) Configured SLD
(3) Create/Maintain necessary Jco Destinations
(4) Create necessary System landscape (SAP_Webdynpro_XSS and etc)
(5) Activated integrated ITS 640 in ECC5
When I try to access any ESS webdynpro iviews from the Portal, for eg the Address iview :
https://Portalhost.domain/webdynpro/dispatcher/sap.com/essusaddr/Per_Address_US
I received the following error :

Hello all,
Can anybody please tell me wht is the difference between IAC and Java IViews and wht configuration we have to do to use java iviews?hi,
<b>IAC iview</b> is used when you want to create an iview of an ITS service. In the thrid step of creating IAC iview we should pass the ITS service name for IAC property.
Steps to create IAC iview.
1. Create a system object for R/3 with ITS property category also.
2. create a Service in transaction using SICF. The below thread will help you.
Running your first ITS WebGUI application in SAP NetWeaver 04 ABAP Edition - NSP
3. create an an iview and give the service name in IAC textbox not R/3 System name.
<b>java iview</b>: if you are devloping an application using Ecllipse or NWDS you can create an java iview. Create the application in Ecllipse or NWDS and export it to the portal as .par file. In the content administration while trying to create an iview you have to choose <b>new from par->iview</b> and choose .par file you have exported to portal and continue.

Hello,
I would like to modify in our system (EP 6 SP 2) the standard MSS Iview "General Data" by deleting some information and adding some specific data.
I have questions about the following steps:
- with a Java Developer Role, where can I get the .par file in the portal?
- with the .par file, could I import it in NWDS or could I modify it directly by decompiling the java classe?
Thanks,
Regards,
Jerome.Hi Jerome,
Changes to the MSS business package should be performed using NWDI as these iViews were developed using webdynpro.Please refer my blog for more details,

Thanks for your reply.
I am able to see the Iview with all the components(textfield,buttons).
But the image is not displayed. and I am not able to check whether the connectivity is been established.
in this part of code
text = new TextView("fgfdg"+Str);
I am assigning the value of "Str", which i get from R/3 to "text",
but in the iview the value of "Str" is not displayed.

API - method for Webdynpro Java iview functionality of Print
I know.. you would love to post me with n different blogs and forums discussion about how to print from webdynpro java application.
But lets read before what i am looking for..
There is standard "Print" function available on webdynpro for java iview.. and layout and all its just fine for us. though we want to trigger this event from a screen button. as going to iview properties is very user friendly.
I was looking for some iview api which can help me.. We are on NW 7.01 SP6 at the moment. And this is for standard ESS applications.
Thanks a lot for your inputs.
Regards,
SudhirHi
You can write Java program for printing. Call the java class from screen (button or Url). Also you can write the content to XMl file.open the xml file in action. so that u will get print preview and print option. -

Hello,
We are having an ESS Iview named "Hire External Applicant" in Portal.
This iview has been customised.
I found that to construct this iview "5. Request Form as Java iView in Enterprise Portal 5.0" section from ISR Cookbook is been used.
i.e. Created a request form using java iview.
This iview is being used in two places :
1. Create
2. Update.
Now Create is working fine.
But when this iview is accessed from Update section...i.e. user press update button:
the customized section in java iview is not getting updated.
Where this problem could be.There is a new form section in existing standard form.
This section contains 4 new customized checkboxes.
When create button is pressed the values from these checkboxes is properly getting updated in R/3.
But when Update is pressed, these values are passing blank "As if nothing is selected" to R/3 module.
But at the time of Update button, all existing standard fields in form are getting updated.
I think that in case of update, these check boxes are not mapped properly to R/3 System.
I opened the par file in NWDS, and found that there is no code for mapping of values, and moreover same iview is working fine while create button is pressed.
Please guide me as of where could be problem.

Portal Java Iview Runtime - Urgentt
dear All Portalers,
we got high issues when SAP ESS/MSS Implementatin for our customer, we got issue about HTTP Session maximum and cause error message "Java Iview Runtime .."
first, this is our landscape
1. We Have SAP EP 7 installed with UME integrated with LDAP (Ms. Exchange 2003)
2. We use SAP ECC 6 SR3 as our Backend System
3. We use ALL SSL Commnunication between Portal and Backend
4. We use SPNEGO for User Authentication Mechanism, so User Join Domain, directly open portal when run Internet Explorer between input User and password
5. Each Uses LDAP mapped use User Mapping
But, after we launch to customer, we got big problem about Session
Here, reproduce the error
1. User Join to Network Domain ( e.g. CORP.CO.ID)
2. After User/laptop join Network Domain and open browser https://portal.CORP.co.id/
3. Directly, User logon automatically at Home of SAP ESS/MSS
4. User finish transaction at SAP Portal and want to Out from Portal by Log off, but after Log off automatically back to entry ( is is Normal ??? )
5. User very annoying, so user close browser
6. After 10 seconds, user Open Browser again, open browser https://portal.CORP.co.id/ but user got this message
"Java Iview Runtime...bla bla bla"
can any help us , i already set OSS Message Very High ... but didn't solve this problem
thanks
regards
ghochiHi Ghochi,
First if you want user not to directly log in to Portal then disable the automatic logon setting frominternet explorer.
Tools > Internet Options > Advance > Enable internet Authentication (uncheck checkbox) restart browser. Next time user will not directly login to Portal. But user needs to enter user ID/PWD every time.
Coming to your problem for http sessions,
1. On click of log off button, sessions are not getting released. Please check what is the value once user clicks on log off button. This you can check in Visual admin.
2. Also, go to SM04 in ECC and check how many http sessions you are having.
Thanks.

Hi,
Can someone please guide me to how I can modify standard ESS/MSS iViews, for example, to remove unwanted UI elements etc. The portal version is EP6. Also, I understand that with EP7 most iViews are Web Dynpro Java/ABAP, can these be modified also? Is there any docs or how to guides which will show me how to do this? Are there any Weblogs out there that anyone knows of? I've been searching and searching but have had no such luck thus far. All help will be very appreciated.
Thanks
Tony.The "cookbook" for ESS is available via service.sap.com (the specific OSS note is attached too can be found with a search on here....sorry, don't know it right off). The cookbook does apply for EP6 and ESS ECC5.0. Basicaly, it steps you through setting up NWDI(JDI), creating your "project", pulling the needed Webdynpro into your NW Dev Studio, modifying it and re-deploying to NWDI and onto the portal.
An even better way....there is an online class available from SAP (it is part of the ERP2004 training) that covers ESS/MSS in-depth as well as modifying the files. The entire course (of which ESS/MSS is a small part) is $500 USD last time I checked....well worth it.
The new ESS/MSS/self-service WebDynpros are based on the Floor Plan Manager framework which can be tricky to understand....the class above helps cover that too...has material I have found no where else but in the class.
Hope this helps. -
MSS - where find code for java iviews and how to copy and extract??????
Hi All,
Not sure if this is the correct forum, so if i'm in the wrong place apologies and if possible could you point me in the right direction. If I am in the right place, here it goes......
we're using R/3 4.7, MSS 6.1.20. We're just beginning to implement MSS. I'm wondering if anyone could give me a couple of examples of which MSS options are based on java iviews, where is the code for these java ivews stored on the system and do i have to do anything special to extract this code.
the reason i want the code is that i want to copy it and see how difficult it is to make changes to the code in netweaver developer studio.
Also, as i'm new to all this, if anyone knows of a good source of info for java iview creation/manipulation, please let me know.
Kind regards,
Liz.Hi,
This is how we access java code for ESS applications. I hope it is the same for MSS as well.
Open your NWDS -> Window -> Preferences -> Java Development Infrastructure -> Development Configurations.
Provide the Landscape directory server in URL field. something like http://<server name>:<port number>. Ping and confirm the connections. Save the settings.
Now select Window -> Open Perspective -> Development Configurations.
Right click on the Offline and select Import configurations. Select remote option and import the respective items from the server. Create a project for the required inactive DC and you will be able to edit the code in webdynpro perspective.
Hope this helps.
Thanks,

Java-iViews-Errors in BP for CRM
After importing BP 6.0 for CRM 4.0, the Java iViews (e.g. Today's Activities or My Tasks) don't work. Instead we get an error like this:
Portal Runtime Error
An exception occurred while processing a request for :
iView : N/A
Component Name : N/A
com/sap/pct/crm/generics/context/CRMContextException.
Exception id: 08:52_11/10/04_0004
See the details for the exception ID in the log file
The WAS and ITS iViews of the BP are running fine and the import log of the BP says the iViews are correctly installed.
Is there something wrong with the JCO?Hi Marko,
I don't know the BP, but this exception clearly states that within the method <i>getPage</i> within the class <i>ListPortalComponent</i> a <i>CRMContextException</i> is referenced (probably should be thrown), which in fact does not exist within the classpath.
<i>If</i> I would have the BP at hand (and you have, that's your advantage), just check if the class exists. If not, you could try a workaround and check the cause for the exception, if you achieve that it should not be thrown, the JVM won't complain...
Is the BP delivered within one or within several PAR's? If it takes several PAR's, maybe <i>CRMContextException</i> is in one, <i>ListPortalComponent</i> in another PAR and no SharingReference could be set (but I wouldn't call this very probable for the common package <i>com/sap/pct/crm/generics</i>; nevertheless, it's an idea).
Just try to analyze around this...
Hope it helps
