BjoernHi bjoern,
You need to Install Java 6 Runtime Environment. I can see that you are using Java 14. SDK. This will not support SAP Widget Foundation. You can download Java 6 [from here|http://java.sun.com/javase/downloads/index.jsp].
Thanks,

SAP widget foundation doesn't start after installation
Experts,
I'm trying to run the SAP Widget Foundation application as a stand-alone.
I have installed the application using SAPWidgetFoundation.jar found through the following link (download package):
https://www.sdn.sap.com/irj/scn/widget-foundation#section2
After installation or when clicking the appliication in the start menu, it should start and display a tray icon. No tray icon is displayed and I don't think it's even running at all.
I am running Java Version 1.6.0_13, Windows XP Pro SP3, Yahoo Widgets 4.5.2
The following lines are saved to the log when attempting to start the Widget Foundation.
10:14:44 [ INFO][main](ApplicationStarter:90) - [Nr:1][94][since:109(1242720883921)]msec: Check single instance
10:14:44 [ INFO][main](ApplicationStarter:69) - [Nr:2][0][since:109(0)]msec: Check Java Version

Does anyone have an idea what I may be missing here?
Thanks in advance,
OlivierHi Olivier,
When you tried to install SAP Widget Foundation as standalone application following SAP Widget Foundation User's Guide - [https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/20e64a36-6f34-2a10-0bbb-aeac6101b93c], did you get the installation result saying "SAP Widget Foundation installed successfully"?
If you got the success message, then try this:
Actually when you go to Start Menu -> Programs->SAP Widget Foundation and click there, a Batch file starts to run, which inturn displays the icon on the tray.
What you could do is, Go to the location where you have installed the SAP Widget Foundation, usually C:ProgramFilesSAP Widget Foundaiton and double click on the "run.bat" file. This may work.
If you did not get the success message, then there would have been some problem during installation, you could uninstall and re install it again.
Let me know if this works.

Component included in SAP NetWeaver Foundation for Third Party
Hi Experts,
Now, our team discussing on how we can use integrate based on ABAP Technology to integrate Enterprise Systems.
Then, we discovered the License, that SAP delivered, "SAP NetWeaver Foundation for Third Party".
I heard this license allows client to develop custom applications on standalone NetWeaver Application Server(ABAP/Java).
I think that the ABAP instance contains SAP_BASIS and SAP_ABA, and I have information that it allows to use also BRFplus,
but it is a little vague what function can be used.
Does anyone knows what component is included that license?
Especially, we want to know whather we can use NetWeaver Gateway with standalone NetWeaver Application Server or not.
Best Regards,
//Naoya TsugoWell, the box is checked for that, so I have to assume that it is included.
What is the confusion?

Unable to refresh cache in SAP PI NW 7.3.1
Hi All,
I am unable to perform full & delta cache refresh.
CR content is not updated(it's below 9.5) -- Does this has anything to stop cache refresh?
I see SAP_XI_ID_SERV_USER role missing - does this has anything to do with cache refresh?
what authorizations are required to perform a successful(full & delta) cache refresh?
Attached is the error which is showing up.
Please help me
Thanks,
RajHi Dheeraj,
Have a look at below link
Missing Authorizations to execue cache refresh for user PICACHEUSER - SXI_CACHE
CPA CACHE refresh 403 Forbidden - No Authorization with PIDIRUSER or PIDIR<SID> -
Hi All,
i changed 1 .js file in mime repository, but the changes are not getting reflected when i run 1 of the WAD templates. it still picks the old .js file. i guess there is some problem related to clearing of cache memory.
Any ideas about how to clear cache in BW?
Thnx in advance
GodhuliHi Godhuli,
You can call transaction <b>RSRCACHE</b> and you can delete all; In OSS Note 456068, you can find all the issues related to this kind of problem
You can also refer oss notes 679609,779015 for OLAP cache invalidation.
Awarding points is the way of saying thanks in SDN!!!

CAL - Connect to an instance of SAP ERP Foundation Extension powered by SAP HANA
Hello,
I created and activated an instance in CAL today, the ERP on HANA trial.
Once this instance is activated ("green button"), the "connect" option appears but I'm not able to connect to it using http or SAP Gui.
I have no firewall, the error is:
This webpage is not available
Could you help me?
Thank you!hi Pierre,
There could be multiple reasons for not being able to connect to the instance:
1. After click create instance, you need to wait for 45 minutes. Also the green botton comes,in the backend it is still working to complete the creation.
2. Once you have IP address, please try to connect to SAP GUI by manually add the server, instance number, etc into SAP GUI. See if it works. In addition, try to connect to BI launchpad via http:<IP address>:8080/BOE/BI.
3. Some user reported connection problem, we found out that certain AWS account may have problem with VPC layout used for this solution. check out the support AWS account:
• Click on EC2 Dashboard in left side navigation of the AWS Management Console • In upper right section of screen under Account Attributes section the Supported Platforms are listed http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-supported-platforms.html

Foundation 2013 Farm and Distributed Cache settings
We are on a 3 tier farm - 1 WFE + 1APP + 1SQL - have had many issues with AppFab and Dist Cache; and an additional issue with noderunner/Search Services. Memory and CPU running very high. Read that we shouldn't be running Search
and Dist Cache in the same server, nor using a WFE as a cache host. I don't have the budget to add another server in my environment.
I found an article (IderaWP_CachingFormSharePointPerformance.pdf) saying "To make use of SharePoint's caching capabilities requires a Server version of the platform." because it requires the publishing feature, which Foundation doesn't have.
So, I removed Distributed Cache (using Powershell) from my deployment and disabled the AppFab. This resolved 90% of server errors but performance didn't improve. Now, not only I'm getting errors now on Central Admin. - expects Dist Cache
- but I'm getting disk operations reading of 4000 ms.
Questions:
1) Should I enable AppFab and disable cache?
2) Does Foundation support Dist Cache? Do I need to run Distributed Cache?
3) If so, can I run with just 1 cache host? If I shouldn't run it on a WFE or an App server with Search, do I have to stop Search all together? What happens with 2 tier farms out there?
4) Reading through the labyrinth of links on TechNet and MSDN on the subject, most of them says "Applies to SharePoint Server".
5) Anyone out there on a Foundation 2013 production environment that could share your experience?
Thanks in advance for any help with this!
Monica
MonicaThat article is referring to BlobCache, not Distributed Cache. BlobCache requires Publishing, hence Server, but DistributedCache is required on all SharePoint 2013 farms, regardless of edition.
I would leave your DistCache on the WFE, given the App Server likely runs Search. Make sure you install
AppFabric CU5 and make sure you make the changes as noted in the KB for
AppFabric CU3.
You'll need to separately investigate your disk performance issues. Could be poor disk layout, under spec'ed disks, and so on. A detail into the disks that support SharePoint would be valuable (type, kind, RPM if applicable, LUNs in place, etc.).

Dear all,
I am developing different scenarios with BPMs accessed by SOAP (Web Services) within SAP-PI.
I am having a lot of problems with some of the XSLT split mappings programs. What's happening is that we have developed various mappings and made changes to them and upon activating them it's possible that they are being incorrectly managed by the J2EE server cache e.g. wrong versions being kept in the cache. The consequence of this is that we obtain different results for the same data input.
Executing the services sequentially, with the same input parameters, we obtain results with different data in a random form that coincides with the different versions of the mappings that we have published to the server.
Could there be an error with the way the java cache works?
I am checking different issues regarding the SAP PI Caché manual ("How to Handle Caches in SAP XI 3.0.pdf"), but I cannot find the problem. Doing testing, I am getting in different moments, following errors:
1. This error occurs sometimes:
com.sap.aii.af.service.cpa.impl.exception.CPADirectoryCacheException: Failed to check secure connection configuration. Reason: com.sap.aii.af.lib.sld.SLDException: Failed to read SLD instance name. Reason: HTTP response code: 503 (Service Unavailable)

I did all checks that came in the manual, but to no avail.
Thanks in advance.
RegardsHi!
According to my Knowledge
1. BPM need to use in final case because it tooks lot of performance issues in RUN time because IN BPM while running your scenario the process is always switch from ABAP stack BPM Process Engine to JAVA Stack for executing the mapping whch you configured in the java stack and again it needs to swtich towards the Process Engine and finally again it needs to swtich towards java stack to ID part through Interface determintation step....
In going all these it takes lot of Load on server and suppose if it is handling very huge data defnitely you ill face performance issues.
2. Also I think there is some authentification issue while running it means defalutly even though u configured any adapter on your user id by default all those adapters run by using ADMINs authentifications check whether it was locked or some other problem.
3. Also check once CACHE thorugh SXI_CACHE and also u can check via RWB-->Cache Monitoring...

How can we reset the SAP cache for users roaming profile in a d?
Our active directory is on windows server 2003.
SAP version 6.40
users work from different workstations in our company with their roaming profile.
printouts are defined by assigning a printer to the terminal (usually the closest terminal to theprinter)
we have some users who have logined to windows, are unable to print to the assigned printer, because the name of the terminal is stuck on another terminal they worked on before.
we think that the the cache in SAP does not update properly.
Where is the SAP cache, is it in the server, or the workstation, or the user profile?
Can anyone help?
Robynall configurations of the printers are correct.
I will try and explain the problem differently:
In general If a user logs on to SAP, we will see in tc al08 the username and terminal the user is working from. (The terminal is the full computer name e.g. WS-KITCHEN).
When a user with the problem logs on to SAP, we will see in tc al08 the username and the name of a terminal he worked from in the past and not the work station he is at present. Therefore his printouts go to the printer that is allocated to the terminal that he worked on before and not the WS-KITCHEN he is working on now.
Thanks

SAP Simple Finance on top of ERP Foundation Extension Trial
Hello Folks,
has anyone tried to install SAP Simple Finance Add-On on top of the ERP 6.0 Ehp7 on Hana Trial Edition?
We need a Simple Finance Demo system and I'm currently finding the best way to get it.
Steps to do on the ERP 6.0 Ehp7 on Hana Trial system:
- Update Hana DB to SPS08
- Update Ehp7 to latest SPS07
- Install Simple Finance
Somebody tried one of these steps?
Best Regardshi Patrick,
First of all, the SAP ERP Foundation Extension trial is there only for 30 days. In addition, you should not do any system landscape level updating/upgrading/adding add-ons, it is not compliant with Trial Terms and Conditions; on the other side, the trial license will not allow all these kind of development-like activities either.
Coming back to your question about the experience, my SAP ERP Foundation Extension RDS project is in the progress to update the trail with sFIN 2.0. What we have done:
1. completed data consistance check
2. finished fin application related preparation
Next week, we will update the system to SP7 and install the sFIN 2.0. Going forward, we will deliver a sFIN 2.0 trial to replace the existing ERP Foundation Extension trial. Planned RTC is by end of June,2015.
Stay tuned with us!

Cache refresh error, while activating changelists
Hi all,

with Errortype: Communication,
"if_http_client receive http_communication_failure"
When I then do a delta or full cache refresh from transaction SXI_CACHE it allways works, even after an error occured before. Some ideas, what I could check?
Thank you in advance..

The file name or extension is too long.
I ignored them and continued the unzipping.
Please guide me as to how we can solve this error.
Ankur
Is it because I am using Eclipse 3.3.2 and not 3.3.0? If yes from where I can download Eclipse 3.3.0
Edited by: ankur malhotra on Jul 25, 2008 7:36 AMHi Ankur,
This happens sometimes because of the Eclipse that you use. Download the Eclipse JEE Version. When you go to eclipse.org and try to download eclipse you can do a comparision of the versions there, You download the version which supports all the web features.
http://www.eclipse.org/downloads/packages/eclipse-ide-java-ee-developers/ganymeder
Check the above link you will be able to see the package details. Please download this Java IDE for EE developers and try installing the SAP widgets foundation then, If you are facing any problems in installing the plugins thru local archived site please let me know.
