Model Execution Problem

Hi
I have this structure of the model
Z_Bw_Exec_Query_Input
               E_Datacol
               E_Result
               I_Params
                           W3Query
                                     att:name
                                     att:value
               Output
               att:I_Query
Z_Bw_Exec_Query_Output
W3Query
Zbwdatacol
Zbwresult
and I am writing this code in wdDoInit() of component controller
Z_Bw_Exec_Query_Input model =new Z_Bw_Exec_Query_Input();
model.setI_Query("ZDDVTEST123");
wdContext.nodeZ_Bw_Exec_Query_Input().bind(model);
W3Query paramElement1 = new W3Query();
paramElement1.setName("FILTER_VALUE_1");
paramElement1.setValue("201033");
W3Query paramElement2 = new W3Query();
paramElement2.setName("FILTER_IOBJNM_1");
paramElement2.setValue("0CALVEEK");
model.addI_Params(paramElement1);
model.addI_Params(paramElement2);
I am getting an error message as follows when I see the preview-
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Couldnt find info for class com.conexa.sap.model.W3Query in model com.conexa.sap.model.BW_Model@59d97818[scope=APPLICATION_SCOPE]

What should I do to resolve this issue?
Thanks and Regards,

Hi Sheik
the structure of the model is like this. Under I_Params node there is a class node W3Query and that has attributes name and value. So basicly I have to assign many elements to I_Params which takes W3Query as parameter. That is why I am creating object of W3Query class and passing that as parameter but unfortunately getting error message.
Z_Bw_Exec_Query_Input
                   E_Datacol
                   E_Result
                   I_Params
                             W3Query
                                       att:name
                                       att:value
                   Output
                   att:I_Query
Z_Bw_Exec_Query_Output
W3Query
Zbwdatacol

Package execution problem with SQLSERVERAGENT

Hello,
I'm having a problem with the execution of SSIS packages: I created locally a package with SQL Server Data Tools, then I deployed it on my server in the SSISDB database. Then I created a job to execute periodically this package with SQL Server Agent. The
package works fine and does everything I want, but I always get a failed notification. In the global view of the execution I can see:
Result: "failed"
Package name: "Package.dtsx"
Task name: "Package"
Execution access path: "\Package"
Every other task returns a success and their execution access path is a subfolder of "\Package". I tried everything I found on the web, check the "Runtime 32bits" box, create a "Job Account" user to execute the package via a
"Job Account Proxy", modify the ProtectionLevel of the package to "DontSaveSensitive", give the "Job Account" user full rights on everything, nothing works.
Do you have an idea of what my problem is and how to solve it?
I must precise that all my packages do the same thing: I have a loop on all the csv files in a folder that for each file loads the contents of the file in my database and the delete the file. I observed that the error message do not appear when there is
no file in the folder when the package executes.
Thanks in advance.

Not sure what error message, is the one "est introuvable.
Cette erreur est retournée par la collection Connections lorsque l'élément de connexion spécifique est introuvable"?
So, here is in short: the ForEach Loop once in its beginning of operation "senses" the files currently present in the working folder. If a new file arrives after this stage, it will not see it.
In your case it seems that the ForEach "saw" a file at the beginning, but it was gone at the time the processing wanted it for execution.
Like many above indicated, the common practice, call
it elegant or not is to indeed move the files to a different directory (working folder). This is done to avoid collisions with some other activity in that folder.
Furthermore, you can have all the files deleted using a ForEach against the working folder as say in
http://beyondrelational.com/modules/2/blogs/88/posts/10178/ssis-delete-files-from-specified-folder-using-file-system-task-in-sql-server.aspx And there is no need to delete the working folder
itself.
The job is run in SQL Server's Agent
need to be set to run using a domain proxy account as it needs write access to the file system.

Logical model - 2 problems (proposal to improve)

hi,
1st problem:
New entity - Add attribute - Primary UID - Apply (Unique identifier is created)
After Primary UID unchecking the Unique identifier is still there, so after OK or Apply, an Error message (Incoplete Unique Identifier) is displayed.
Now it is necessary to modify/delete Unique identifier manually - could it be this operation automatized?
2nd problem
after duplication of Entity with Unique identifier (Copy - Paste) the new Entity is renamed right, but name of UI in new Entity is unchanged.
this cause problem after Engineer - DDL with duplicate constraint name
thank u,
mat

Web service model initialization problem

Hello, every one
I have some trouble in the initialization of web service model.
I tested the web service through web service navigator and it was ok.
My context structure is:

The exception is:
LocalizedMessage: Service call exception; nested exception is: com.sap.engine.services.webservices.jaxrpc.exceptions.XmlMarshalException: XML Serialization Error. Property [Low] of class [com.pjs.wcalist.model.wsmodel.proxies.types.p1.ZbapiRWapius] must exist and can not be null. This is required by schema description.
In the test of the web service the Low of the ZbapiRWapius is not needed.
And after setting the value, the exception told me that I must set the tWca, ie the subnode of the result.
The problem is: I do not know why the setter method of the original bean of the "parameters" only accept the parameter of array type .
I think the parameter I set may be wrong.
When I deal with another web service model(the level of the structure is not deep), it is ok.
Could someone give me some suggestion or explanation?
Thanks a lot.

Command line program execution problem.

Hey there, I'm about to complete my Java thesis project, but I can't fix a problem: i have to find a command line programme (which is in python but i think its not a big deal) through a java programme. Getting some information around I ended up i could execute the program with the command:
Process proc = Runtime.getRuntime().exec("...");
and create the streams:
OutputStream out = proc.getOutputS 14.49
InputStream in = proc.getInputStream();
the problem is that calling a programme which prints on screen something and then it ends (ex. ipconfig) the following sequence works out:
do
int i=in.read();
if(i==-1) break;
System.out.print((char)i);
}while(true);
instead in the specific case of the programme that i need to execute it canno't work because this programme after its opening prints a couple of lines, at this stage you need to type the input in and when the eof font is sent the output is printed. i've tried to send the input thru OutputStream but the execution gets stuck when it reads the output (in.read());
Can you guys help me out? What do i need to do? Please it's very important, let me know ASAP.
Thanks very much,
Fabio

I would not recommend the use of raw "InputStream" for much of anything.
Try Scanner if you can use JDK5, if not, try BufferedReader.
Scanner:
Process proc = Runtime.getRuntime().exec("...");
BufferedOutputStream out = new BufferedOutputStream(proc.getOutputStream());
Scanner in = new Scanner(proc.getInputStream());
while(in.hasNextLine()) {
     String s = in.nextLine();
     System.out.println(s);
}BufferedReader:
Process proc = Runtime.getRuntime().exec("...");
BufferedOutputStream out = new BufferedOutputStream(proc.getOutputStream());
BufferedReader in = new BufferedReader(new InputStreamReader(proc.getInputStream()));
String l = " ";
while(l != null) {
     l = r.nextLine();
     System.out.println(s);
}

SQL Data Modeler - Startup Problem

Hi
I've created a Relational Model with Oracle SQL Developer Data Modeler, with a few tables, and everything was working ok.
Yesterday I made some changes to the model, added columns and another table, saved the model and closed the Data Modeler.
Today - when I tried to open the Model, I only get an error "Some objects are not loaded correctly. See the log file for details"
The log at the bottom of the Data Modeler only shows: "Open Design: "nameof model"" and no details of what went wrong. No other details is provided, and as far as i can see - and now I can't view the model at all.
Any ideas how to find the problem/ fix it in order to get the created Model back?
Thanks
Coenraad

Execution problem with java.exe

Hi everybody. I am a student in a belgian university, and i've got a problem with the execution of my binaries in the JVM.
I'm developping my project with Eclipse. When I build the project, Eclipse launch perfectly my application with javaw.exe (I supposed it because it's written in the console when I run the project).
Thus, I wanted to try to launch my application by myself, to check if everything is right...
My project is composed like this :
- creavea/src : the sources of my project (a package called "main" , and a package "com.creavea. ..." and other .jar files like a MySQLConnector/J, edtFTPj, the JOutlookBar by lf2prod, ...
- creavea/bin : Eclipse puts the binaries there, when I run my project.
- creavea/files : Somes files like configuration files for my application, etc ...
- creavea/images : Images for my interface.
- the main class, containing the pubilc static void main method, is called CreaGesta, and is in the "main" package.
creavea is the name of my project, but i think you supposed it !
I want to run the binaries, then i do this :
- I open a ms-dos console
- I'm going in the C:\eclipse\workspace\creavea\bin folder
- I execute the command : java main.CreaGesta ...
And it doesn't work :'( ! An error appears :
Exception in thread "main" java.lang.NoClassDefFoundError : com/lf2prod/common/swing/JOutlookBar.
This class, JOutlookBar is used by my application, and the jar file containing the class is in my /bin folder. I can't understand, i'm a little bit disapointed.
It's my first big project in Java, then i don't really understand what's happening. So if someone can help me, it will be really nice for me ! Thanks a lot for your help !
J�r�me - Belgium

Thank you for your reply Atmguy ! I put in my command the classpath of the jar's who are in my /bin folder.
Like this : java -classpath edtftpj-1.4.9.jar; jdom.jar;l2fprod-common-outlookbar.jar;mysql-connector-java-3.1.8-bin.jar main.CreaGesta But now, i've got an other error message :
Exception in thread "main" java.lang.NoClassDefFoundError : main/CreaGestaOh, it changed ! but I don't understand the problem . What does it mean? "Java cannot find the class main/CreaGesta", or "An error occured in main.CreaGesta" ?
Can somebody help me to solve this new error ? Thank you !

Hi,
I reselved the problem by just copying the FastInfoset to the jaxrpc\lib directory (I am sure this should work in a different way).
Well, the next problem I am getting is that the "XMLStreamWriter" class cannot be found. This class is contained in jsr173_api.jar.
I guess my main question is the following:
Which projects are necessary to get this simple helloWorld example to work?
I did set the JWSDP_HOME varible. Is there another setting I have to make to have all necessary jar-files available and to be able to run the samples?
Could anybody point me to a tutorial that does not only show a few lines of code (as the HelloWorld sample in the JWSDP-Tutorial) but that would instead lead me through a step-by-step sample application that I write by myself and actually runs at the end? The example in the JWSDP-Tutorial uses all kinds of existing config files which are not explained.
Thanks for your help.

Reuse Model Project - Problems in the integration of 2 projects with ADF

Hi there.
We have in production one application with ADF and UIX of average composed dimension for 9 placed services inside of one root to share cache. At this moment we are to develop another application, much more simple, to join with the first one. The problem that we have, is the synchronization of caches. Therefore for example, let us assume in the first application we insert a record in the table of employees, in the second application we do not obtain to see this employe while we do it execute query.
Anyone can explain to us some way of different applications share cache of model in some way, or to make synchronization of caches between them, or other soluction ...
Thanks in advance.

Sounds pretty difficult, the whole cache thing has been brought up so many times. You havfe this problem even when one user tries to view the changes of another user. The short answer is you just have to be smart about when to clear cache/reexecute query. If your page has a common entry point do it there, otherwise simply put a refresh button on the page that will do it. I think people get too wound up on caches, unless your app is under some serious load, clearing the cache quite often is not going to hurt anything, after all you do have the database doing caching on it's end too.

2 monitors on 2012 Core i7 13 inch model - any problems?

I have a Core i7 Macbook Pro 2012 13 inch model
I've done some reading up and have read in places that 2 monitors with a USB3 HDMI device is possible...
BUT... because it's a 13 inch model, and that will ONLY be able to have 2 screens with the laptop closed
Is this true?
Also... I've seen USB3 extensions for under £30 and also other Startech ones for more than double the price
Do the cheap ones have any problems that the more expensive ones don't?
Generally: do the USB3 extentions cause any undesirable problems?
Thanks

something else i didn't mention: would having 2 monitors effect the performanc of my macbook pro in any way?
If the resolution of the external monitors approaches the limits of what is supported by the laptop's video card, and you are using applications that lean heavily on the graphics processing hardware, there may be some performance degradation. This may be even more so on computers like the 13-inch that doesn't even have a discrete video card.
USB monitors will be driven by the USB bus which is driven directly by the CPU, so as long as you have CPU capacity it should be OK, but again if you were doing CPU-intensive work that may impact the performance of USB monitors. Do note that USB monitors tend to respond more slowly than regular monitors, because USB monitors are limited to the speed on the USB bus (and affected by other loads on the same bus including hard drives and other devices you may have on it), while normal monitors are driven by very fast graphics hardware, which is often the fastest hardware on the computer and many, many times faster than USB 2.

RFC model creation problem in NDS

Hi All,
I am facing a strange problem while creating a RFC model in NDS.
After providing all the logon informations to server, the editor says "Connect to SAP gaetway failed. Unknown hostname..."
Where as I can connect to SAP system through the SAP gui using the same logon details.
The Hosts file does have entry for the hostname.....Tried using a newer 7.0.10 version, but problem still persists.......
What might be the loose end here!!!!!!!!
As far I know, NDS uses tcp/ip protocol to connect to servers & the Host file entries should help it in getting connected to SAP.....
Does it use some other layer to connect??? HTTP???
Any pointers are welcome. Thanks in advance..

Sandip

Hi Sandip,
It fetches and populates values from SAPLOgon.ini file stored on you machine.
Same file is used to show system list in SAPGUI logon pad.
So, If you are getting system on logon pad then it should show same in the dropdown.
One more point:
Is you backed system uses message server to rought to hte server? If so, then provide Host or IP of the message server instead oh Application server.

Bhavik
