Problems with creating model in Email Web Service tutorial

Hello!
In the moment, I'm trying to follow the tutorial "Using an Email Web Service in Web Dynpro". I followed all the steps in the chapter "Generating a Model from the WSDL Description", but after typing in the mentioned WSDL description "http://webservices.matlus.com/scripts/emailwebservice.dll/wsdl/IemailService" in the "New Model" wizard, I'm getting the error message, that the WSDL file is not found or not valid and no new model can be created.
So I'm quite stuck. What am I doing wrong? Did anyone encounter the same problems?
Greeting
Bärbel

Hello Baerbel,
I could not reproduce this error and never had this before. What you could do in the meantime is taking the wsdl description from the url and copy and paste it into a notepade file. Then please save it under emailwebservice.xml onto your hard disc and select it from "local file system or url" and take it from the path of your local file system.
Hope that helps!
Best regards,
Karin

Hi Vivek,
This problem occurs when Web Service provider is not reachable , it means the server which provides services to the WSDL is temporally down or not reachable . To check whether the services is reachable , you could paste the WSDL URL in your internet browser , if it opens then problem is with NWDS configuration of proxy else sever is not reachable .
In your case problem is not with NWDS but with server as it looks that it is temprorarly down. To avoid such problem in future you could also store the WSDL file locally on your system and then can import ( obvioulsy you requires at least once to get the WSDL ) . This will help only while modelling the application to run you will require the service provider to be up and runnning
You could use other tutorials to try AWS Model in Web Dynpro .

Problem with datetime data type in Web Service

Hi,
I created local ABAP proxy based on a WSDL and some of the fields for the SOAP methods has data type datetime:
name="MsgEndTimeStamp" type="s:dateTime" />
name="MsgStatus" type="s:string"/>
Since ABAP stack doesnt support dataTime data type it has created the proxy method with data type STRING. Now when I call the proxy method (consuming the service) I get an error:
<CODE>SoapFaultCode:4</CODE>
<ERRORTEXT>Server was unable to read request. --> There is an error in XML document (1, 626). --> String was not recognized as a valid DateTime.</ERRORTEXT>
I am sure others have faced the same issue. Can someone help?
Thanks

Thanks but I dont think that link is much relevant to the problems I am facing, because I cannot change the web service definition as it is used by many others. Also the target application runs on oracle so thats why some of the fields are datetime and I dont want to change that, even if I could.
I am just stuck in creating the wrapper program to call the service since the SAP converts datetime data type to string and when the messages gets to the application it cannot convert string -> datetime.
thanks anyway

Problem with file receiving through abap web service

Hi experts,
I need to created web service for import file from .NET application into SAP.
ABAP function expect hexadecimal string (same as GUI_UPLOAD / GUI_DOWNLOAD) but hexadecimal string from C# is too long (double longer), and I have no idea how to convert it. Also there is a problem with code page...
Is there some better way to do this? Any idea is welcome!

Hi Nemanja,
Please bear in mind that your SAP system is based on UTF-8 encoding. Since you have the xstring length doubled, most probably your sender system uses UTF-16 encoding. So what you need to do is change the encoding used by your .NET application when sending the data to SAP.
Alternatively, you can try using XSL Transformations in ABAP to have the input data converted from UTF-16-encoded xstring to ABAP structures. You can find a little example in this thread: ABAP data to XML conv with UTF-8 encoding and custom namespace. The point is to start your XSLT with the following: <?xml version="1.0" encoding="utf-16"?>.
Hope this helps,
Greg

Problems with UTL_DBWS calling out a web service.

I´m using ORACLE 10G 10.2.0 and i ´ve downloaded the dbws-callout-utility-10R2.zip utility l´ve unziped it and launched it .
the command loadjava -u SCOTT/passwd -r -v -f -genmissing dbwsclientws.jar dbwsclientdb102.jar ended without errors.
then I gave grant access using the following commands
the environment variable is
$TMPCLASSPATH=$ORACLE_HOME/sqlj/lib/dbwsa.jar:$ORACLE_HOME/jdk/lib/dt.jar:$ORACLE_HOME/jdk/lib/tools.jar:$ORACLE_HOME/sqlj/lib/runtime12.jar:$ORACLE_HOME/sqlj/lib/translator.jar:$ORACLE_HOME/javavm/lib/aurora.zip:$ORACLE_HOME/rdbms/jlib/xdb.jar:$ORACLE_HOME/lib/xsu12.jar:$ORACLE_HOME/jlib/jndi.jar:$ORACLE_HOME/rdbms/jlib/aqapi.jar:$ORACLE_HOME/rdbms/jlib/jmscommon.jar:$ORACLE_HOME/lib/xmlparserv2.jar:$ORACLE_HOME/jlib/orai18n.jar:$ORACLE_HOME/jdbc/lib/ojdbc14.jar

COMMIT;
call dbms_java.grant_permission( 'SCOTT', 'SYS:java.lang.RuntimePermission', 'setFactory', '' );
COMMIT;
then I created the package running UTL_DBWS .SQL scripts
when I run a test for calling out the web service I got the next error.
ORA-29532: UNCAUGHT JAVA EXCEPTION : Java.Lang.IllegalAccessException: java.lang.ExceptionLnLn

name 'oracle.jpub.runtime.dbws.DbwsProxy.createService(java.lang.String,java.lang.String) return long';
Is necessary to install the jpublisher in addition for a sucessfully web service calling out?
what goes wrong?
Thanks for the soon answer.

I have exactly the same problem.
All possible grants are made.
Running as SYS is not functioning as well.
The same installation (the same jar's, the same utl_dbws version, the same database version) does function on two other (developers team's) servers .
The differences are:
Where it functions: Oracle database Enterprise edition on Windows (Windows 7, Vista)
Where it does not function: Oracle database Stadard edition on Unix
I have gone though a decent number of forums and other on-line resources with no success. Solutions available are to grant missing permissions. However these solutions are based on the assumption that under SYS user everything functions properly.
In my case, this does not function even under SYS as SYSDBA.
I will highly appreciate any recommendations!

Michail

Problems with deep request structure in web service

I'm having problems when trying to consume an Enterprise Service-like web service in my Web Dynpro application. The web service FindXByElements has a request-structure as follows:
XByElementsQuery
-ProcessingConditions
-QueryHitsMaximumNumberValue
-QueryHitsUnlimitedIndicator
-XSelectionByElements
-ID
-Year
Regarding the structures on level two, the structure ProcessingConditions are of the global data type "WITHOUT_LASTRETURNED_QueryProcessingConditions" and are therefore typed. The structure XSelectionByElements on the other hand are just a "level" in the request structure and are therefore not typed. Both structures have occurrence 1 so they have to be filled with input data.
The code in wdDoInit in the Component Controller looks like this:
QueryXInModel model = new QueryXInModel();
wdContext.nodeRequest_FindXByElements().bind(wdContext.createRequest_FindXByElementsElement(new Request_FindXByElements(model)));
wdContext.currentRequest_FindXByElementsElement().modelObject().setXByElementsQuery(new XByElementsQuery_Sync(model));
//Processing structure
wdContext.currentXByElementsQueryElement().modelObject().setProcessingConditions(new WITHOUT_LASTRETURNED_QueryProcessingConditions(model));
//Selection structure
wdContext.currentXByElementsQueryElement().modelObject().setXSelectionByElements(new XSelectionByElements(model));
The last row generates the following exception:
java.lang.IllegalArgumentException: Cannot perform write operation 'setRelatedModelObject' on target role: Class 'XSelectionByElements' is not compatible to class '$002fWsdlDefinitions$002fWsdlTypes$002fXsdSchema$002fXsdComplexType$005b3$005d$002fXsdSequence$002fXsdElement$005b2$005d$002fXsdComplexType' of target role 'XSelectionByElements' in model class 'XByElementsQuery_Sync'
There seems to be a problem to bind a non-typed structure element to a context node since the processing structure is working fine but the selection structure are not.
What am I doing wrong, anyone got any clues?
/Oskar

Hi
QueryXInModel model = new QueryXInModel();
wdContext.nodeRequest_FindXByElements().bind(wdContext.createRequest_FindXByElementsElement(new Request_FindXByElements(model)));
wdContext.currentRequest_FindXByElementsElement().modelObject().setXByElementsQuery(new XByElementsQuery_Sync(model));
//Processing structure
wdContext.currentXByElementsQueryElement().modelObject().setProcessingConditions(new WITHOUT_LASTRETURNED_QueryProcessingConditions(model));
//Selection structure
wdContext.currentXByElementsQueryElement().modelObject().setXSelectionByElements(new XSelectionByElements(model));
XByElementsQuery
ProcessingConditions
QueryHitsMaximumNumberValue
QueryHitsUnlimitedIndicator
XSelectionByElements
ID
Year
as
          QueryXInModel model = new QueryXInModel();
           Request_FindXByElement request = new Requst_FindXByElement();
            ProcessCondition   processCond = new ProcessCondition(model);
            QueryHitsMaximumNumberValue qhMaxNumValues = QueryHitsMaximumNumberValue(model);
      QueryHitsUnlimitedIndicator qhUnLimind = new QueryHitsUnlimitedIndicator(model);
        XSelectionByElements selecByEle = new XSelectionByElements(model);
                 processCond.set....();
                 qhMaxNumValues .set...();
           and so on
                request.set....();
wdcontext.nodeReqestFindX..bind(request);
in the above during the values you will automatically get the set values .

Problem with signed SAML assertion and Web Services Manager

Folks,
I’m having some issues trying to generate a proper signed SAML assertion using JDeveloper 10.1.3. I am securing a java proxy class using the wizard as described in http://www.oracle.com/technology/products/jdev/howtos/1013/wssecure/10gwssecurity_howto.html .
On the OWSM side, I have a service that I am securing with SAML - Verify WSS 1.0 Token. If I set the "Allow signed assertions only" property to false I can complete the service call. However, when it is set to true I am receiving the following fault: javax.xml.rpc.soap.SOAPFaultException: SAML token verification failed.
When I examine the message going to OWSM in a packet analyzer, it is missing the signature in the SAML assertion. The <saml:Assertion> tags looks like:

Any help is greatly appreciated.

Thanks for the response. I am not using any pages for this application yet... just calling the web service from SOAP UI or any Web Service testing tool causes the problem.
All that has to be done to replicate it is to build a simple EJB 3.0 JPA bean using the entities from tables wizard and then add named query as follows:
@NamedQuery(name = "BomHeader.findByDesc", query = "select o from BomHeader o where o.bomDesc like :p_bomDesc")
then build a session bean with the wizard that includes the JPA persistence unit and the entity and subsequently use the wizard to wrap the session bean in a web service.
The whole replication process should take 5 minutes if you have some database tables to work with. It breaks when the web service is called.
Thanks in advance

Problems with permissions to execute a web service in a drop down list ...

Hello:
I have created several iView with VC and I integrated it into guided procedures process. In some of that VC iViews I have drop down list that are filled with data retrieved from web services created by us that doesnu2019t require any authentication.
When I execute my VC iViews with the Administrator user everything works ok, but when I execute it with a different user the drop down list doesnu2019t retrieve any value, as if the corresponding web services where not executed.
If I assign the "super_administrator" portal role to those users everythingu2019s goes OK. But I don't want that users to have that permission. Can anyone help me to identify which granular permission do I have to assign to that users in order to get the iView working as they are working for the "super_administrator" role?
Thank you in advance.
Ricardo Zengin.
Edited by: Ricardo Zengin on Jul 6, 2009 6:35 PM

I solved this issue giving administrator read and end user permision in te portal systems creadted for the web services to a group to which all my users belongs.

Problems with Community Bridge (MS REST-Web-Service)

Hello,
few days ago I started experiencing problems while connecting to Microsoft TechNet Forums
by using Community Bridge 3 (MSDN/Social/Partner) and "Forté

I subscribed:

Could you confirm the problem ?

Problem with special characters when calling web services via ISG

Hi all,
I have a problem when trying to send or retrieve strings containing some special characters via Integrated SOA Gateway.
For example, when I call a PL/SQL function via ISG that returns a string containing curling single and double quote characters, these are not represented by valid XML character entity references. So when trying to open the response XML (returned by ISG) in a browser, I get a parser error...
Has anybody had a similar experience with ISG? How can I resolve that - is it an ISG bug?
Thanks

Problem with email web service

I'm trying to implement the email web service tutorial. When I run the application I get the initial page but when I try to send mail I get the following error:
Service call exception; nested exception is: java.net.UnknownHostException: proxy
We don't use a proxy server so I'm not sure why this error appears.
I tried to disable http proxy server in the Systems Administration.
Any ideas would be greatly appreciated.
Ross

Hi Michael,
This exception is thrown if at runtime for service exceution the host ip address could not be resolved. It could happen if service provider server is down, not responding or out of network . Another cause could be if you have not configured the proxies in Visual admin to go out of network .

Email web service example as an Adaptive Web Service Model

Hi All,

Hi Naresh,
See if any of the following threads help, all are related to the same wsdl:

WSDL description for email Web service

hi
while creating an application for sending and receiving emails, i created an Import Web Service Model and selected WSDL source as UDDI/URL. Then i entered http://www,abysal.com/soap/AbysalEmail.wsdl
but it can not be saved and gives the error " Invalid WSSDL or WSDl not found, please spcify different WSDL or check WSDL location entered on previous wizard page"
please help.
Thanks in advance.

Hi,
Try creating a web service of your own(out of a simple Java class or ejb) and check if it is working fine.
If yes, then it might be the problem with the internet connection that you might be using. There might be some restriction in your connection that is preventing your system from creating the proxies related to the wsdl.
If no, please let me know what the error is.

How do I create a "document-centric" Web Service?

By document-centric I'm talking about receiving a SOAP message on the server-side, where the initial parsing and security processing (this aspect is very important) is performed but then allowing the developer to access the delivered "payload", i.e. the XML, and perform whatever mapping/processing that is required without automatically mapping to the "standard" auto-generated Java objects.
It is important that the client receives the "full" complex WSDL and can therefore generate their proxy classes with whatever tool (or language) that is appropriate.
On the server side we do not want to create hundreds (if not thousands) of Java Bean clases as we already have the legacy code to map XML to Java. The idea is that JAX-RPC only instantiates the SOAPElements that represent the "raw" message, or, if possible, doesn't instantiate any objects whatsoever.
I've spent many days now trying to find a single well-worked example for this type of Web Service without success - many, many references of the style "..and you can then create a document style web service.." but without the all important "how".
From what I've read a custom type-mapping and/or serializer/deserializer could be the answer but again no good, solid examples are forthcoming.
Another alternative seems to be to create the server side stub-classes using a "dummy" WSDL with the elements set to "anyType" but then distribute the "genuine" WSDL to the clients - we've got a simple example of the kind working but I don't like the idea of "tricking" the system in this way.
I'm working with WASD 5.1, which in theory conforms with JAX-RPC so any ideas offered here should also apply in that environment.
Has ANYONE successfully created a service of this type?
Any help with this issue would be very much appreciated and rewarded (with Duke Dollars of course).
Chris.

Chris,
I too noticed that most vendors take the RPC centric approach. Its because most of the industry examples of how WSs were used were simple enough to implement using RPC and anything more (document literal) would add to the complexity of implementation. This is something that is feared by many developers, especialy the .Net crowd who seem to want everything done through a wizard menu interface and don't care about other WS implementations at all.
This is sort of changing. J2EE 1.4 is WS-I compliant, so when you compile server side ties from WSDL you can specify a document literal option and WS-I compliance. This gives you access to the SOAPElement objects. There's still issues with going between W3C DOM and SOAP elements but that's just API inconvenience, not a show stopper. As the inudustry develops more complex WSs we will see the vendors change their tools to better support this...
Anyway, some more help...
I use the the following wscompile options to build from WSDL for document literal WSs.
wscompile.bat -d . -nd . -s . -f:documentliteral -f:wsi -keep -model model.gz -import config.xml
wscompile.bat -d . -nd . -s . -f:documentliteral -f:wsi -keep -model model.gz -gen:server config.xml
My "wrapper" elements look like this...
<xs:element name="AComplexXMLResponse">
 <xs:complexType>
 <xs:sequence>
 <xs:element ref="myNS:MYComplexXMLType"/>
 </xs:sequence>
 </xs:complexType>
</xs:element>
If I do this:
<xs:element name="ASimpleXMLResponse">
 <xs:complexType>
 <xs:sequence>
 <xs:element name="AName" type="xs:string"/>
 </xs:sequence>
 </xs:complexType>
</xs:element>
I still get the JAXRPC language bindings to a string, but in my case I don't really care. This may well be different for you.
What I do to manage these elements is to split up the WSDL, WS wrapper element definitions and actual data XML schema definitions into separate documents. This means I have a WSDL which IMPORTS my message schema (this is where I define wrappers for in and out XML) which INCLUDES the actual DATA XML schema that I have.
The WSDL import looks like this:
<types>
 <xs:schema>
 <xs:import namespace="http://schemaURI" schemaLocation="./relativePath/WrapperElementSchema.xsd"/>
 </xs:schema>
</types>
The wrapper element schema has:
<xs:include schemaLocation="./ActualDataSchema.xsd"/>
This way I can easily replace the wrapper documents with just anyType references if something doesn want to play nice. The data schema file and the WSDL stay the same. This minimises the impact on what you have to change in your distribution. This is important as the WSDL is often generated on the fly by your WS environment and so can not be easily changed once you build your WSs, but the schema files it references are easily changed without affecting your code.
Another reason for the wrapper elements was a JWSDP 1.2 issue (I don't know if this has been fixed in 1.3), where if you had the same method parameter signature in a web service (the parameters it took were the same XML types, for instance if you have an add and update methods for the same document input) JWSDP would get confused at runtime. It did not take account of the SOAP action that came along with the request to determine which operation to call. It just took the incoming XML, saw that it was of a certain type and it passed it to the first operation that took this element, which is VERY wrong. By using the wrapper elements, I could give all my input and output elements for each method different names (I used a naming stragegy that appended a 'request' or 'response' string to the method name to form a method parameter element name. This is a pain in the ass, but works and does wonders for interoperability with other WS vendors. Like I said before, I've got this working with JWSDP, BEA and .Net servers and clients.
Hope this helps,
If you think there is a real need for a public HOWTO on this, I could write one with a full step by step guideline that shows where I broke my legs getting this stuff to work. But this would eat into my sleep time :-/ TO JUDGE INTEREST I call on all people interested in a tutorial to respond to this thread (esp people involved with the JWSDP WS tutorial documentation). If I get 5 or more different people responding I will loose some sleep for the good of this community. Otherwise, I will just try to help you when I have time to read the forums.
