Consuming XI Webservice in WebDynpro - Data Type error

HI All,
I have a scenario, to access web service in web dynpro java, which is created by XI ..Now I have WSDL file. Using that WSDL file I have imported web service model(DEPRECATED method) in my web dynpro java.
Once web service model is imported I have done the mapping 'model to component controller'. After that I did not write any coding, and just deploy the application. While deploying the application I am getting an error as given below,
com.sap.tc.webdynpro.services.exceptions.TypeNotFoundException: type java:byte not found.
Reason of this error:
Attribute type does not support web dynpro java ,Because XI side that corresponding attribute type is base64binary once model is imported in to web dynpro that base64binary attribute type is automatically taken as byte.
Please help me ASAP

"Schema validation found non-data type errors" error when passing a string value to date field in infopath

Hi,
I have an infopath web brower enabled form. In the form i have a date field.
I am passing the data from the database to that field using the C# code.
But, as the field from database is coming as string, i am getting an error, and i am not able to assign the value.
I get the date value from database as "3/25/2011 12:00:00 AM"
I used the below code:
[CODE]
if (objInfopathFormcData.myRecievedDate != null)
myRoot.SelectSingleNode("/my:myFields/my:field97", NamespaceManager).SetValue(objInfopathFormcData.myRecievedDate);
[/CODE]
I am getting the error as "Schema validation found non-data type errors".
How to set the value for a date field in Infopath.
Thank you

HI,
I fixed it:
Below code is used to fix:

The return of the "Unexpected Data Type" error

I've searched the forum and only found discussions of this from over a year ago, so either I'm a loner or this is rearing its ugly head again.
I've got a project that I've been working on between two machines, both running AE 11.0.2.11 with the same plug-ins. One is a macbook pro, one is a macpro. Both are running 10.6.8 (I believe that's snow leopard). I've been saving the project files and assets to the dropbox folder on my machines so that everything is always in sync between them. ***It's been working flawlessly for months.*** I haven't updated anything recently, other than installing Adobe Acrobat on the desktop machine a few days ago.
This morning on my desktop machine, I couldn't get the project to open without getting the "unexpected data type" error. Holding down shift did nothing. I instinctively started a new project and imported the .aep I was trying to open. No errors! Then I tried to change work spaces and the error came up again. I hit caps lock and tried again. No go. At one point the workspace drop-down had bullets next to *two* of the workspaces, as if they were both active simultaneously.
My workaround for the moment was to go to my dropbox on the website and revert to a previously saved version of the same project (thank *YOU* dropbox) from a few days ago. That opened fine, though it's missing a few hours' work.
My fear is that this will recur and I will have to keep going back in time to keep working (two steps forward, one step back) and I've got a deadline to meet. I will try to stay away from custom workspaces, as one poster to this forum says they are generating that error in CS6 (no helpful replies to that thread).
Anyone else experiencing this in 2013? Any ideas? All help is much appreciated.
AE CS6 11.0.2.11
Mac Pro OS v 10.6.8
Processor: 2x 2.66ghz dual core intel xeon
12Gb 667mhz DDR2 RAM

I just started getting the same error today. Never would've imagined workspaces would have ANYTHING to do with this. But I just went to workspaces and clicked 'reset workspace' for whatever I was on, reloaded the project and no error. WTF Adobe??

Based on your post there is an error in you initdg4msl.ora file............ make sure you the database connection is correct and you add the two statement to the file
for example
Should be: HS_FDS_CONNECT_INFO=YOURSQLSERVER//YOUR DATABASE
Make sure you to add the following to the same file (see page 92):
HS_NLS_LENGTH_SEMANTICS=CHAR
HS_FDS_CHARACTER_SEMANTICS = TRUE
HS_KEEP_REMOTE_COLUMN_SIZE=ALL
Rerun the ETL process

InfoPath - "Schema validation found non-data type errors." at XmlWriter.Close()

Greetings,
I'm creating a form that allows for emailing attachments however I am having an issue. When I try to attach a file, I get an "Schema validation found non-data type errors." error message. It seems like it's something with the XML structure and
I cannot find anything wrong.
Here is the code:
string myNamespace = NamespaceManager.LookupNamespace("my");
using (XmlWriter writer = MainDataSource.CreateNavigator().SelectSingleNode("/my:myFields/my:Email/my:AttachmentGroup", NamespaceManager).AppendChild())
//Write to XML
InfoPathAttachmentEncoder myEncoder = new InfoPathAttachmentEncoder(currentFile);
writer.WriteStartElement("Attachments", myNamespace);
writer.WriteElementString("attachment", myNamespace, myEncoder.ToBase64String());
writer.WriteElementString("attachmentCheckbox", myNamespace, "false");
writer.WriteEndElement();
writer.Close();
Here is the structure of the XML (root node is myFields):
<my:Email>
<my:AttachmentGroup>
<my:Attachments>
<my:attachment xsi:nil="true"></my:attachment>
<my:attachmentCheckBox>false</my:attachmentCheckBox>
</my:Attachments>
</my:AttachmentGroup>
<my:emailAddress>[email protected]</my:emailAddress>
<my:subject>Paychex ESR Services Paperwork</my:subject>
<my:body/>
<my:selectAll>false</my:selectAll>
</my:Email>
Attachments is the repeating group in this case.
Can anyone spot where the error is coming from?
Thanks!

Consuming Webservice in WebDynpro - Content-Type issue

Hi,
I am getting a shortdump when consuming WebService in WebDynpro.
I trace it back to the class CL_SOAP_HTTP_TPBND_ROOT method GET_HTTP_HEADERS whereby the
value = 'text/html; charset=iso-8859-1' while the constants tsrc_soap_11_http_content_type = 'text/xml' ; tsrc_soap_bx_http_content_type = 'application/x-sap-bxml' ; tsrc_soap_mtom_http_cont_type = 'application/xop+xml' ; tsrc_soap_mp_http_content_type = 'Multipart/Related'. Because of this Content-Type difference my WebDynpro application dumps?
Any ideas how to solve this problem?
Thanks.
Regards,
Amel

hi,
Few indroductory sessions
/people/thomas.jung/blog/2007/12/17/consuming-services-with-abap -Consuming webservices with webdynpro.
It is possible to create webservice in ABAP as well as in Webdynpro.
ABAP Webservice:
http://wiki.open-esb.java.net/Wiki.jsp?page=BAPIWEBSERVICE
http://www.sappro.com/downloads/SAPXI.pdf
Webdynpro Webservice:
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/244e7923-0a01-0010-5887-fe0b0c6dbb8d
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/30f1b585-0a01-0010-3d96-ad0ea291c4f9
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/media/uuid/db785a70-0701-0010-858c-eee0ec4fe1b3
In Web Dynpro ABAP there is nothing special about calling a web service. Unlike WD Java, there are not dedicated model object types in WD ABAP. WD ABAP simply has the ability to interact with other ABAP development object types. You can call function modules, ABAP classes, even modules in old dynpro apps.
So calling the webservice from ABAP therefore is just the process of generating the ABAP Proxy Class. This is the same process regardless of if you want to use this proxy class from WDA or any other type of ABAP development object. You can then call the proxy class from WDA just like any other type of ABAP class. There is a service wizard option in later support package levels that includes an option for ABAP Proxy classes - although it doesn't generate the proxy class it just generates the code and context for the call to an already existing proxy class. The service wizards in WD ABAP are not required however. They are just shortcut code generators and often can't even generate a complete context for a complex web service proxy - so expect to do some manual adjustment after running the wizard.

Hi colleagues
I am trying to consume a webservice "BORM_API_A1S_GET_UPD_SW_VECTOR" in webdynpro, it is an external webservice
i have followed the below steps and ended up with an error
Steps:
1) created a Adaptive web service model
2) got the WSDL source from "Remotelocation/fileSystem"
3) given the WSDL URL Acess as "e:///C:\Documents and Settings\Desktop\BORM_API_A1S_GET_UPD_SW_VECTOR.wsdl"
4) created a service group
5) then i have done the " model to controller" binding and "controller to view" binding
6) in the INIT method of controller i have creted the instance of the model and binded it to the context element
7) set some some values in the init methiod(for input parameters)
8) designed a view to get the values that are set into the input parameters
9) Configured the service group
i am getting an error saying

I think i am doing wrong service confuguration
steps i have followed to Configure the service group are given below
1) logged into http://ldcidwd.wdf.sap.corp:50000/nwa
2) SOA management-->technical information --> system connections
   here i have selected the provider systems tab, and created a new provider system of system type "Java"

Consuming ABAP Webservice in Webdynpro app

Hi,
I have wrote a webdynpro app for consuming ABAP webservice. I used the procedure in the link below
http://wiki.sdn.sap.com/wiki/display/WDJava/ConsumingABAPWebServiceinJavaWD
Everything seemed to be went well, I created model and Webservice destinations. I have written the code for calling the webservice, which does not return data as part of response. I mean though the RFC returns data at the backend,its not showing the returned records in the webdynpro table.
I have also tried checking the same by setting external break point. when the webservice is executed from my webdynpro app,it goes to the ABAP debugger and i could clearly see the records in the export parameters of RFC,but the same is not returned in the reponse object.
Could any one let me know what could be missing. Any help is greatly appreciated?
I have used the following code in Init method of my View
Request_ZMYRFC input=new Request_ZMYRFC (model);
wdContext.nodeRequest_ZMYRFC ().bind(input);
ZMYRFC req= new ZMYRFC (model);
req.setPUserid("EDLAS00C");
req.setPLtc("E");
input.setMYRFC (req);
IWDMessageManager manager = wdComponentAPI.getMessageManager();
    try
    wdContext.currentRequest_ZMYRFCElement().modelObject().execute();
      wdContext.nodeResponse().invalidate();
      wdContext.nodeZMYRFCResponse().invalidate();
      wdContext.nodeReturn_res().invalidate();
     wdContext.nodeItem_res_ret().invalidate();
      wdContext.nodeILtcg_res().invalidate();
      wdContext.nodeItem_res_ltcg().invalidate();
    catch(Exception e)
      manager.reportException(e.getMessage(), false);
Thanks

santosh,
Check provider system defination in nwa for webservice.After this mapp the provider system and service group after wd app deployed.This is mandatory while consuming webservice in webdynpro for latest versions of CE7.11 or later.for reference check this article/document. http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/50d70a19-45a3-2b10-bba0-807d819daf46

Consuming PI Webservice from Webdynpro Java Not working

Hello SAP,
Environment: CE 7.2.
Resolution expected immediately, Helpful answer is highly appreciated.
Is the namespace should not exceed 60char for PI Webservice, for executing the webservice from Webdynpro Java.
I tried with all the options in executing the PI Service from Webdynpro Java, None of the options worked. I am facing the below error while I was calling the PI Webservice.
I don't see any problem from Webdynpro Java, what ever the procedure I have followed is the standard procedure.
Fortunately when I execute the service from Webservice Navigator, it is working as expected. The same webservice when I consume it from Webdynpro Java it is not working
Options tried so far:
1) Published the Services to Service Registry and there by consuming the PI Service from Service Registry - Not worked
2) Tweaked the URL with few options - Not worked (Tweaking the URL, ex: portType, Binding)
3) Changing the Business Systems in PI and there after calling the service - Not worked
4) Initializing the code, instead of creating Service Controller and calling the PI Service - Not worked.
5) Created a Provider System and tried to call the PI Webservice from Provider System - Not Worked
For all the Options, I am facing the same error which is provided in the screenshot.
Below procedure which I have followed for calling the PI Webservice:
1) Created Adaptive Webservice Model
2) Provided PI Webservice URL (It prompts for PI System UserId and Password)
3) Selected Option - No Service Group Configuration
4) Provided Logical Destination
6) Completed creation of Model
7) Added the model as a UsedModel
8) Right Click on Comp Contr. and selected Apply Template and Created a ServiceController for the model (Entire mapping to comp contr, Initializing the nodes is taken care by Service Contr.)
9) Created an Template Action button and there by calling execute method which is auto rendered from CompContr..
10) Build the project.
11) Activated the code and Run the Application.
12) Getting the below error which is showed in the message.
ERROR MESSAGE:
Exception on execution of web service on destination 'GetPIHRPeopleData' for operation 'SI_CreateHRPeopleData_OS' in interface 'SI_CreatePeopleCompany_OS'

Hi Sankar,
If the webservice is working fine in the Wsnavigator then there is some problem with importing the webservice in webdynpro for Java. Please check the required parameter for creating the Adaptive Webservice Model. After adding in the used model and compoent controller binding, you need to write code for to execute the webservice model.
Please check the code for initialization and execution for the webservice and then test it.

Hi Venkatramana,
The class of the ProxyGenerator is com.inqmy.lib.wsdl.ProxyGenerator. It is located in <SAPj2eeEngine_install_dir>/cluster/server/additional-lib/inqmysoap.jar or <SAPj2eeEngine_install_dir>/alone/additional-lib/inqmysoap.jar file. In addition the following JAR files must be included in your classpath - mail.jar, activation.jar, inqmyxml.jar, inqmysoap.jar, located in <SAPj2eeEngine_install_dir>/cluster/server/additional-lib/ or <SAPj2eeEngine_install_dir>/alone/additional-lib/ directory. You need also the inqmy-lib.jar file in <SAPj2eeEngine_install_dir>/cluster/server/lib/ or <SAPj2eeEngine_install_dir>/alone/lib/ directory in order to run the generator.

Query Parameter Data Type error betwee IE6 and IE7

Hello all.
This is a strange one. Using MII v12. When setting parameters for a SQL query from Javascript, the query executes properly on IE7 but generates errors on IE6. The errors are JDBC errors having to do with "Conversion failed when converting datetime from character string." and "Error converting data type varchar to numeric." I don't get any browser errors, only Java errors and NetWeaver log entries.
What is the source of this data typing error?

Hi, Sparks.
Actually, IE was always an anomaly when it came to proper typing of objects in Javascript, so it let you get away with things that really shouldn't work.
In general, you should use the Number Javascript type for number properties (e.g. setRowCount(), setXAxisMinRange(), etc) and strings for just about everything else. If I recall, Javascript will handle most of the type conversions to a String property, but not necessarily to a Number property.
You can use the parseInt() and parseFloat() methods to convert from strings to numbers in Javascript.
In general, it's a good practice to be "type aware" in your Javascript code anyway, and this will ensure that it runs in other browsers and future browsers.

java.sql.SQLException: ORA-00932: inconsistent datatypes: expected DATE got NUMBER
No matter what i do, i get this error.
The query in the VO is as below
select * from hr_all_positions_f
where trunc(sysdate) between trunc(effective_start_Date) and trunc(effective_end_date)
Please advice.
Thanks

your query works perfectly in sql developer...
as suggested by kumar expand your columns instead of using *
Also check the data types dynamic where clause if any.
