Error with UWL

Hello everybody,
I am trying to test the "Accessing UWL Notifications from Web Dynpro Using UWL API" tutorial, but I get an error in line:
IProviderConnector procon = uwlService.getRegisterProviderConnector(IProviderConnector.ADHOC_WORKFLOW_CONNECTOR_ID);
"The method getRegisterProviderConnector(String) is undefined for the type IUWLService".
I have the import com.sap.netweaver.bc.uwl.IUWLService so I do not know why this error is showing, can anyone help me to solve this?
Thanks in advance.
Carol

Hi Carol,

Errors with UWL iViews

Hi All,
We're on EP 7, sp13. ever since we first installed ep7, we've been seeing errors on all the UWL iViews including the UWL administration iView (under System admin). Upon clicking the iView, i see "Portal Runtime error" and this is true for all users including admin users, i tried previewing the iViews from content admin but still got the same error msg.i retrieved the following from the logs via nwa:
Content pass of Application Integrator failed.
Component Name:       com.sap.portal.appintegrator.sap.WebDynpro,
Context Name (iView): pcd:portal_content/every_user/general/uwl/com.sap.netweaver.bc.uwl.uwlSapWebDynproLaunch,
Top Layer:            WebDynpro/TopLayer,
Producer ID (FPN):    null,
System Alias:         SAP_LocalSystem,
i also referred to the below thread on the same issue:
UWL Administration error
but im really not sure what is the impact of deleting the .bak par file etc as mentioned in the thread above..
Can somebody pls advise on how to troubleshoot this and configure the uwl iViews/service? Thanks!!
cheers

UWL connection is fine as workflow is getting trigered and i can see work item in manager's inbox. I have created a dedicated template system for UWL with Web AS as ECC host:port number and Web AS path as /sap/bc/bsp/sap.
And maintained other connector and ITS properties and all connection test successully passed.
As we have only one sever so while creating system using load balacing template, was not able to identify message server name which is to maintained in case load balancing system.
Please help me finding out where can be the issue.
Thanks,
Honey
Thanks

When registering the system in UWL, specify a WebDynpro Launch System. That should resolve the issue.
WebDynpro Launch System -- create a system of type WAS and mention the WAS host name and WAS path.

Guided Procedures with UWL

Ciao SDN,
I am trying to configure Guided Procedures with UWL.
I followed the guide <a href="https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/6b66d7ea-0c01-0010-14af-b3ee523210b5">How to..configure UWL with the GP engine</a>
But when a user starts a task via UWL obtains the message:
"Could not retrieve process instance: contact your system administrator"
Someone can help?
Regards
Luca

Hi Luca,
I faced the same problem some time back, so I don't remember exactly, but let's see how we can solve this....
First of all I want you to have a look at this SAP Note, and do what's recommended in this:
<a href="https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes/sdn_oss_bc_gp/~form/handler%7B5f4150503d3030323030363832353030303030303031393732265f4556454e543d444953504c4159265f4e4e554d3d31303236313139%7D">Error by opening GP work items from UWL</a>
Follow the steps given in Solution. Remember that the file that you need to download ie uwl_gp_config.TXT has to be renamed as uwl_gp_config.XML before uploading.

Odd Error with decode function in Order By Clause

I am trying to compile a procedure and can't get around an error with a dynamic order by that doesn't make much sense to me. I can repoduce the error with a plain select statment in sql plus so I can rule out a declaration error. Here is an example with 2 numeric columns and a date column.
select task_id, display_date, remark_id from task_list
where task_id > 1000
order by decode('Task_ID', 'Task_ID',Task_ID, 'Display_Date', Display_Date, 'Remark_ID',Remark_ID)
returns the error:
select task_id, display_date, remark_id from task_list
ERROR at line 1:
ORA-00932: inconsistent datatypes: expected NUMBER got DATE
I'm not sure why this error is occuring, because it doesn't even hit the Display_Date field in the Decode statment. If I take the Display_date out of the statement, it runs properly. If I change Display_Date to To_Char(Display_Date) it also runs fine, but the sorting is incorrect. Also I'm running 9.2, and do not want to use dynamic sql to build my query. Any Ideas out there as to the cause of this error?

I did find a workaround to this issue by breaking the decode statment into three separate statement, but I still think that the way it is written above should work, and may be a bug, or an error that I don't understand fully.
The Order by was rewritten like this:
order by decode(pSort, 'Task_ID',Task_ID), decode(pSort, 'Display_Date', Display_Date),
decode(pSort, 'Remark_ID',Remark_ID);
Thanks

XML Publisher Error with reports published in XML publisher

Hi All,
I am geting the following error with a report published using XML Publisher
The XML page cannot be displayed
Cannot view XML input using style sheet. Please correct the error and then click the Refresh button, or try again later.
The system cannot locate the resource specified. Error processing resource 'http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.d...
How can i Rectify this?

Hi Ark,
In order to generate a report using xml publisher. we need the following.
1. XML Data
2. Template file (RTF/PDF/..)
XML data will not be created by the template file.
We will be required to create XML data. One of the easiest way to create xml output is using the RDF. We can change the rdf output type in the concurrent program to XML.
Once the xml and the template is available, "XML Report Publisher" will be able to generate the output in the required format.
Thanks,

Graphic problems/errors with Mainstage 3 and MBP (15'' 2011)

Hi,
I bought Mainstage 3 for my MBP (15'' 2011).
When i click con "perform" i get graphic errors.
I have the same issue with the old Mainstage version since Mountain Lion.
Also a fresh installation didn't help.
I think i'm not the only one with this issue!
I don't know how to report a bug?
Perhaps someone can help me.
(and I'm probably not the only one (see feedback in Apple Store) If you also have this problem, please add a comment with your configuration (Hardware, Software))
/forgotten ebi
So, here an example how it looks like when i click on "perform":

Same configuration,same problem. BUT I found a workaround.
Mainstage has this error with the AMD video card and/or a second monitor connected.
With a little app (http://gfx.io) it's possible to really force the MBPro to use the Intel Graphics card.
This will work only with the internal screen, not with a second screen connected.
And sometimes you need to restart, to really make the Intel video card free.
This works fine...In the meantime of a fix.

HI BI gurus,

Do you have any idea how to fix and solve this problem? We try to activete the infoset in Italian but the error remains.
Thanks for any help.

I am trying to download my photos from my iphone to my mac-iphoto. It keeps trying but about halfway through it says there is an error with a photo therefore it wont download any of my pictures or videos. It wont tell me which picture is the issue.

I took a lot of pictures and video on my recent trip to Ireland. Now I am trying to download the photos and videos from my iphone to my mac - iphoto. I have tried 3 times and each time (at a different point) I get a message telling me that there was an error with one of my photos and it wont load the pictures. Help!!

Try using Image Capture to download to a folder on the Desktop. If there's a damaged file on the iPhone that's preventing the download you can isolate it with Image Capture and then delete it from the iPhone.

I do not think I missed anything installing NW CE 7.1, but this error makes me think that some plug-in was erroneously left out of the install.
Incidentally, I can continue onward and build an app (this is obviously a tutorial), but when I try to deploy I get the following error:
The deployment of the archive failed with an exception!

Again, this looks like I am missing some components.
Any assistance is greatly appreciated.
TB

Further developments: As you may note from the error message, DS is looking for com.sap.ide.metamodel.core.services.eclipse in both the C: and the E: drive at the same time. In fact, this file exists in the E: drive subdirectory listed, so I obviously have an error with two drive designations being concatenated. Does anyone know how I can change the lookup directory for this dependency (or any dependency)?
Thanks,
TB

PeopleSoft XML Publisher report error with java.io.FileNotFoundException

The weird thing is I was able to run this report without any issues few weeks ago although another user also ran into same error. The PeopleCode step that has been identified is essentially same in the two reports. I checked the app server and the directory does exist as well as the xml files for the two reports. The problem does not occur in test environment, just in production. Any help would be appreciated.

We encounter the same problem. Did you get the answer for this issue? Thanks in advance.
