@ DATA ELEMENTS V/S BUILT IN DATA TYPES

Hi,
I have 15 fields in a custom table. All the fileds need to hav a definition of char- lt 2.
But the Description i each differs only wrt to the NUMBER sequence.
eg. level 1, level 2...level 15.
Now what is a recommended way to go about it.
Should we define 15 different DATA ELEMENTS for the same, resulting in 15 new objects in the dictionary.
OR should I go in for a simple Built In data type.
I know data elements have advantages when it comes to a. F4 help and Table Maintainance. Is the advantage so significant that we can do with 15 additional objects?
Please Advice.

hi Anand,
there are hundred thousands of object in the Data Dictionary, so 15 won't harm much On the other hand, if you build up an ALV list based on this table, than it is good that you have these texts there with translations, etc.
hope this helps

External SOAP client Accessing Webservice using built in Java Data type

We have built a webservice and deployed it on WLS. We accessed this from a swing
client it works fine.The webservice methods uses non-built in JAVA data types
as parameters.These are Value Objects and the JAVA Serializer and Deserializer
classes are generated using Ant task itself.The client coding uses Value objects
given by the Client_jar (generated using <Clientgen> ant task) to pass to the
webservice. We dont want to go by this way.Is there anyway were in we can pass
parameters to the method which expects non-built in java datatypes?
Why i am asking this is, i want to know how an external client (.Net client )
will be able to exceute my webservice (i.e., passing the required Object which
the method is expecting)?

Hi Anish,
Well first off, your web service doesn't send or receive "objects". It only sends
and recieves XML, which is in turn converted to/from Java objects at invocation
time. Second, a .NET (or Perl, or Python, or C++) client will be able to call
your web service, because the wsdl.exe tool (for .NET) will generate "programming
language specific" objects from the <types><schema> elements, in the WSDL of your
web service :-) The wsdl.exe tool will create C# objects from the WSDL, that will
convert XML to/from C# when your web service is called. That's the beauty of XML
schema - it's a "universal typing system", so it's not tied to a particular programming
language. The only issue is whether or not the web services platform vendor's
XML Schema/WSDL processor, can successfully process the WSDL. Some vendors have
more complete implementations of the WSDL and XML Schema specs than others, so
expect varying success here. The one in WLS 7.0 is pretty good, so you shouldn't
have too many problems consuming WSDL generated by .NET tools (or any other tool
for that matter).

Hi Naichen,
You're going to need to register some type mappings in your client code :-)
To know which ones, you should examine the <your-service-name>.xml file, in the
client proxy .JAR, which is produced by the clientgen Ant task. It should contain
XML that looks something like this:
<wsdd:type-mapping-entry xmlns:lcl0="http://www.openuri.org/"
class-name="org.openuri.www.invoke"
type="lcl0:invoke"
serializer="org.openuri.www.invokeCodec"
deserializer="org.openuri.www.invokeCodec">
</wsdd:type-mapping-entry>
<wsdd:type-mapping-entry xmlns:lcl0="http://www.openuri.org/"
class-name="org.openuri.www.invokeResponse"
type="lcl0:invokeResponse"
serializer="org.openuri.www.invokeResponseCodec"
deserializer="org.openuri.www.invokeResponseCodec">
</wsdd:type-mapping-entry>
You'll need to create type mapping calls in you client code that looks like this:
import javax.xml.rpc.encoding.TypeMapping;
import javax.xml.rpc.encoding.TypeMappingRegistry;
import weblogic.webservice.core.encoding.stream.SOAPElementCodec;
import weblogic.xml.xmlnode.XMLNode;
import com.bea.xml.XmlObject;
TypeMappingRegistry registry = service.getTypeMappingRegistry();
TypeMapping typemapping = registry.getTypeMapping(SOAPConstants.URI_NS_SOAP_ENCODING
typemapping.register(
 javax.xml.soap.SOAPElement.class,
 new QName("http://www.w3.org/2001/XMLSchema", "anyType"),
 new SOAPElementCodec(),
 new SOAPElementCodec()
typemapping.register(
 javax.xml.soap.SOAPElement.class,
 new QName("http://www.openuri.org/", "YourXMLBeanClassDocument"),
 new SOAPElementCodec(),
 new SOAPElementCodec()
YourRequestXMLBeanClassDocument request = null;
YourResponseXMLBeanClassDocument response = null;
// invoke operation
try
 XMLNode xmlNodeResponse = (XMLNode)call.invoke(new Object[]{ asXMLNode(request)
 response = YourResponseXMLBeanClassDocument.Factory.parse(xmlNodeResponse.toString());
 log("inStock(String,Call)", "response.xmlText()=\n" + response.xmlText());
catch (Exception e)
 e.printStackTrace();
private static XMLNode asXMLNode(XmlObject xmlObject) throws Exception
 XMLNode xmlNode = new XMLNode();
 xmlNode.read(xmlObject.newInputStream());
 return xmlNode;
You may not have to do the type mapping for the invoke and invokeResponse types
(or any type relating to an operation/operationResponse element), but I'm pretty
sure you'll need to do it for the XMLBean types, used as input arguments (or return
values) to the web service operations. Send me the WSDL, and .xml files from the
client proxy .jar, if you can't figure things out from the info I've provided
here. I'll send you back what the client code needs to look like, based on the
contents of these two files :-)

Error serializing non-built in data type

hi
I am getting the following exception while accessing a webservice which uses non-built-in

Its called ProcessingOrderTO.
The ProcessingOrderTO has three sub-types.. one of which is a Collection
Does anybody encountred this before
I have also attch the WSDL generated .

Hi Mik
Thanks for these suggestions.I have now completely moved to specific types, instead
of the Collections and ArrayList.
Things seem to be working fine ....thanks for all your help
thanks

Hi Jas,
My mistake. I copied the code from a DII client and you are using a Stub
one :-)
The correct code is:
TypeMappingRegistry registry = service.getTypeMappingRegistry();
Where the service variable is what was returned from your XXX_Impl()
call.
You don't have to cast anything, because the object returned from that
method
already extends javax.xml.rpc.Service.
w.r.t. you "moreover" text:
As long as the definition of the non-built-in types is the same as the
WSDL you
sent earlier, you shouldn't have a problem. The question I have is why
are you
a using java.util.Collection object on a web service operation's method
signature,
in the first place? When you do this, you do to things:
1. Producing WSDL that has xsd:anyType for element types. xsd:anyTypes
are fine
for defining XML grammars (i.e. WSDL, SOAP, etc.), but they add too much
mystery
to a business service. They basically tell the WSDL consumer, "the content
of
this element can be anything, so you'll have to figure out what it is
when you
get it. Hee, hee, hee!"
2. Introducing Java-specific classes into your web service. If the extrasList
element always contains the same type of elements, the type for it should
be an
array of whatever that object is. If you used an ArrayList because you
don't know
how many elements this will be, you can still use it in the implementation,
and
call the toArray() method to return a typed array.
To me, it just seems wrong to use Java container objects (i.e. ArrayList,
Collection,
HashMap, Set, etc.) in a web service operation's method signature, because
it
goes against the "programming language agnostic" idea of web services
:-) Just
my two cents.

Hi Jas,
From the stack trace, it looks like you are using a JAX-RPC stub client.
Our java.util.Collection
serializer/deserializer is assigned to the "java:language_builtins.util"
namespace,
so you'll need to register the ArrayList and Collection in the TypeMappingRegistry.
Here's a code snippet:
import java.util.ArrayList;
import java.util.Collection;
import javax.xml.soap.SOAPConstants;
import javax.xml.namespace.QName;
import javax.xml.rpc.Service;
import javax.xml.rpc.encoding.TypeMapping;
import javax.xml.rpc.encoding.TypeMappingRegistry;
import weblogic.xml.schema.binding.internal.builtin.JavaUtilArrayListCodec;
import weblogic.xml.schema.binding.internal.builtin.JavaUtilCollectionCodec;
TypeMappingRegistry registry = ((Service)port).getTypeMappingRegistry();
TypeMapping mapping = registry.getTypeMapping(SOAPConstants.URI_NS_SOAP_ENCODING
mapping.register(
 ArrayList.class,
 new QName("java:language_builtins.util", "ArrayList"),
 new JavaUtilArrayListCodec(),
 new JavaUtilArrayListCodec()
mapping.register(
 Collection.class,
 new QName("java:language_builtins.util", "Collection"),
 new JavaUtilCollectionCodec(),
 new JavaUtilCollectionCodec()
//invoke the web service operation that uses the ArrayList and Collection
There use to be a problem were the type mapping information in the
MyServiceClient.jar
(the one that the clientgen Ant task produces), was incorrect, butI
think this
was fixed well before WLS 8.1 :-)
I haven't tested the above with WLS 8.1 SP 1, but I think it may fix
the problem
you are having.
BTW:
JavaUtilArrayListCodec and JavaUtilCollectionCodec are in ${WL_HOME}/server/lib/webserviceclient.jar.

How to create a generic stack (whose elements can be of any data types) ???

How do you define a "Stack" class that takes the Data type as its constructor argument ,and creates a new instance of that stack type ??? e.g. Stack("double") should create a stack of doubles ,and so on...
     Putting it in another way, how do you go about defining a Stack ,if you are not sure what data types will be pushed into it at runtime ??? Making a Stack of Objects doesn't seem the appropriate choice since, in that case also, you won't be sure of which of the "parseInt(),paresDouble(),Integer(),Double() etc." functions to retrieve the value.

Write your own stack class which delegates push and pop calls to an internal instance of the java.util.Stack. In addition the class has an attribute of type Class. When the push method is invoked the object in the argument will be tested whether it is an instance of the class stored in the type attribute. If not an IllegalArgumentException should be thrown.
Here is the minimal code for such a type-save stack (the main method shows its usage):
import java.util.Stack;
public class TypeSaveStack {
    private Stack _stack = new Stack();
    private Class _type;
    public TypeSaveStack(Class type) {
        _type = type;
    public void push(Object element) {
        if (_type.isInstance(element)) {
            _stack.push(element);
        } else {
            throw new IllegalArgumentException(element
                              + " is not an instance of " + _type);
    public Object pop() {
        return _stack.pop();
    public static void main(String[] args) {
        TypeSaveStack doubleStack = new TypeSaveStack(Double.class);
        doubleStack.push(new Double(Math.PI));
        System.out.println(doubleStack.pop());
        try {
            doubleStack.push("foo");
        } catch (Exception e) {
            System.out.println(e);
}

JAX-RPC - dynamic wsdl - non-built-in data types

I thought my recent exp with developing a JAX-RPC client using a dynamic wsdl to communicate to a non-weblogic Web Service might help somebody out there. :-)
JAX-RPC Mechanism in Weblogic for dynamic_wsdl seems to work only with built-in data types. Weblogic also supports non-built-in data types, but you need to do some extra work! For the user-defined objects, you need to generate their types and register them.
Note: The samples given in Weblogic 8.1 do not use non-built-in data types!
Make sure you use the ant task "autotype" in your build.xml to generate the appropriate types (objects to support java-xml and xml-java converstion), types.xml from the wsdl. Register the types.xml file in your calling client code.
If you do not use register the types for the user-defined classes used in the web services method signatures, then you are likely to get the foll. exception.

Data types - integer element...

Hi all,
I have a little doubt!
Im creating a data type and when I need to specify the length of my integer element with fraction values, I have two gaps to fulfill: first TotalDigits and the second is FractionDigits. My question is: If I have an integer (7, 2) my TotalDigits is equal to 9 or 10? I dont know if coma (,) counts in TotalDigits?
Thanks in advance,
Ricardo.

Hi Ricardo,
Yes, i agree its better to solve in mapping , you can use DateTrans, please see my replies in this thread and other replies you will get a good idea,
Conversion for String to Date?
And in case you are willing to learn about data types and xsd in SAP XI, Did you see this pdf,
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/25c78f79-0801-0010-1e8d-c7f911cf25d1

Element VS attribute in IR when we create data type.

hi guruz,
when we make data type in IR ,and while creating node ,according node we give type(Element ,attribue etc).
what is diff between element and attribute.
please help me
warm regards.

Hi,
You create complex data types using elements and attributes in the XSD editor
Element
Create structured data types. Elements that have a type cannot contain subelements.
Example Instance
<myElem>
<f1> Value of f1 </f1>
<f2> Value of f2 </f2>
</myElem>
Attribute
Add attributes to elements. Attributes cannot usually have subnodes.
Example Instance
<myElem myAttr="AttributeValue">
Element Value
</myElem>
You can flag an attribute as optional or required in the Occurrence column. These values mean the same for elements with an occurrence of 0..1 or 1. The only difference between elements and attributes is that attributes cannot have subnodes and that the same attribute cannot be used more than once in an element.
Hope this will clarify you.

Is it possible to get the element data type of a Queue from itself?

Hi everyone,
i have a Q that has a cluster as element data type.
now when i want to enqueue
i'll use bundle-by-name
and for that i'd have to have my data-type present
(long cable from whereever (possibly from where i obtained the Q).
my question is,
whether there is a method/property-node/something that allows me to
wire the Queue Refnum into it and receive the element-data-type,
so i can then input into the top of bundle-by-name?
(i really dont want to have that cable all over the place)
the reason i ask here is that
the help for the outgoing Queue Refnum from the Obtain Queue method,
shows the element-data-type and so i hope there might be a solution.
thx for your time
and cheers
j
Solved!
Go to Solution.

If I understand your question correctly, the answer is "Yes, it's very easy ..."
The answer is "Preview Queue". Here I create a Queue of some mysterious type (it's a cluster having a Thing and a Center, but you don't know that yet). I take the Queue reference from whereever I can find it and pass it into Preview Queue Element. I take the output and use it to define my cluster in Bundle by Name.
Two caveats. This copies the first element of the Queue into the cluster, so you probably need to be sure to define all of the elements of your cluster. But what if the Queue is empty (as mine is, above, as I just Obtained it) -- well, that's why 0 is wired into the TimeOut input, since I do not want to wait "forever" (-1) for the empty Queue to have an element! Turns out that even in this case, you still get the correct Cluster elements!
Neat, huh?

Type of X equals which data elements or data type

Hi ABAP Experts,
I declareted variable type of X in my program.
(Example TYPES: BEGIN OF T_XML_LINE,
         DATA(1024) TYPE X,
       END OF T_XML_LINE.)
But I want to create structure with SE11 Tcode in my program. But I dont know Type of X equals which data elements or data type and length.
Thanks for help.

Hi,
You can use the below data type in data dictionary
RAW:   Uninterpreted byte string, maximum length of 255 in tables
LRAW: Uninterpreted byte string of any length, but has to be declared with a minimum length of 256
RAWSTRING: Uninterpreted byte string of variable length

Attaching a Cluster of 2 elements data type to dynamic data type wire.

Hey Folks,
How do I attach a cluster of 2 elements data type of wire with a Dynamic data type wire?
Or a Build XY Graph to a curve fitting2.
Thanks for the help.
Ty

Hi Ty,
Try to use the "Express-VI Curve Fitting" which is at: Functions-> Signal Analysis -> Curve Fit.
You have to put this VI before the "Build XY Graph".
Otherwise, u can convert the siganls types by using the "Convert from Dynamic Data"
which is at : Functions-> Signal Mamipulation -> Convert from Dynamic Data.
Hope it Helps....

OBIEE-Answers Problems with NVARCHAR2 data type elements

Hello experts,
After we completed the .rpd development and ported to the real-time environment, when we try to create requests in Answers of Presentation services by selecting certain columns only and try to see results, we are getting an error if the columns are of NVARCHAR type. The error is given below.
This is stopping end users being not able to create any answers/requests. Please suggest how we can resolve this or if any specific things need to be done to solve the problem.
Error Codes: OPR4ONWY:U9IM8TAC:OI2DL65P
State: HY000. Code: 87720170. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 17001] Oracle Error code: 24328, message: ORA-24328: illegal attribute value at OCI call OCIAttrSet. [nQSError: 17007] Error while executing OCIDefine routines. (HY000)

Hello Damon,
Thanks for the response.
We have also tried to query the same data through SQL*Plus and it went well. We had no issues with any data. Also the .RPD is working in our local system with the same data, on windows OS. But when we port the .RPD in the Server (Sun Solaris) we are having problems with the columns which are considered as NVARCHAR2 in the database and VARCHAR in the Physical layer of BI.
We observed there is no NVARCHAR2 data type supported in BI administrator in building the RPD. Is there any other datatype supports the NVARCHAR2 datatype in BI?
Thanks,
Narasimha

Performance and data types: which to use?

Hi All,
I am wondering what data type to use and the effect of them on memory/speed.
1. What is the difference (if any) of using sgl, dbl, int etc. Looking at the LabVIEW help there seems to be a range of 8-256 bits of storage according to the data type. Is it basically choose the one with the smallest storage that can fit the data?
2. I currently have a cluster flowing through subVI's. The cluster contains the start time (or freq), the delta t (or f) and the array of data (about 500-5000 elements). I tried to use the waveform datatype but it couldn't handle a delta t of 2 nanoseconds (500 MHz signal). Am i ok using the cluster, or should i seperate the components and pass them along? What data type should i use for each of the components?
Thanks

There are three main issue to consider.
Range and accuracy. If you need a very high level of accuracy, then you will need to use the extended data type or even create your own, although that's unlikely.
Memory. Yes, SGL takes less than DBL, but unless you're dealing with really huge amounts of data this won't matter.
Coercion. Most built in functions work on DBL. If you wire a SGL into them, they will coerce it, possibly creating a copy of the data and increasing your memory usage.
To sum it up, most of the times it would be best to use the default DBL. It's highly unlikely you'll need one of the others.
As for your second question, it sounds to me like the data is a single organism, so I would say you should leave it in the cluster, but that really depends on whether the functions need it or not and whether you're constantly bundling and unbundling the cluster. Note that 5000 elements is far from being a large array and you shouldn't have any problems handling it.
As for the timing unit, if you really only have 5000 elements (that's 10 microseconds of data?) then you should not have a problem with using a U32 with a nanosecond as the base unit. That should give you the ability to measure more than 4 seconds.

Hi all How to define data type 'P' in structure.

Hi all,
I need to create data element having type P with 2 decimal pt in se11.
Plz suggest me which type should I use to create such element as there is no data type as P in se11.

Hi,
Yes there is no data type 'P' in se-11 for data element.
there two way you can define the D.E
-one is by define with type 'CURR' and give length and decimal places suppose if you define cust_money as curr length is 12 with in you can give decimal places as 2 or 3 etc a/c your requirement.
-secon one is you can use the type as 'DEC' and give the legth and decimal places as explained above.
before creating the data element you can check r they any built in dataelements avialbe suppose for DEC* give in se11 and press F4 then u can find out the list of D.E like there are already some d.E like dec8_2,dec25,DEC11_2 etc...
Reward with points if helpful.

Vijay
