Dynamic webservice client for User-defined datatypes

Hi All,
I have a webservices with user-defined datat types. I want to write a dynamic client that will work even if there are any changes in the wsdl, so that I do not want to recompile the client or make any changes on the client side.
I tried using DII but we need to modify the custome objects and recompile the same. Suggest me any alternative.
Regards,
Sanjay

Rob, unfortunately not. If I ever come across the solution, I will post it here.
The reason I wanted to use weblogic webservices was to take advantage of the asynchronous webservice functionality. I ended up using xfire instead for my webservices, as we already had that in place in the application, and then using polling clients to get the response. Not an ideal solution, but it works very good anyway.

Marcus

Help needed for User-Defined Datatype

Hi All,
I have one table which has User-defined Column Datatype.
Now Client wants us to rename the User-Defined Datatype for some Standardization process.
How to do rename of it, coz Rename old to new doesnt work in Oracle 10.2.0.4G for TYPES.
So we re-created it with the new names. Now our Problem is how do i re-assign the column datatype with the New User-Defined DataType.
Regards,
Prathamesh

The Only Solution that i could found was - Create a new column with new User-Defined Datatype, copy the old column values to New Column, then drop the old column and rename the new Column to Old Column
ORA-22859:     invalid modification of columns
Cause:     An attempt was made to modify an object, REF, VARRAY, nested table, or LOB column type.
Action:     Create a new column of the desired type and copy the current column data to the new type using the appropriate type constructor.

Dynamic Webservices Client

Hey ,
I have an application which requires to talk to 2 different published webservices
from 2 different systems. Now instead od designing static webservice clients for
each of these systems(which would involve having separate proxy jars etc),
I am planning to design a dynamic webservice locator and invoker....
I know that we can have webservice clients which are dynamic to the extent that
we can create proxy objects at runtime once we know the endpoint WSDL..
eg:
ServiceFactory factory = ServiceFactory.newInstance();
QName serviceName =new QName targetNamespace,"net.xmethods.services.stockquote.StockQuoteService");
QName portName = new QName(targetNamespace,"net.xmethods.services.stockquote.StockQuotePort");
QName operationName = new QName("urn:xmethods-delayed-quotes","getQuote");
URL wsdlLocation = new URL("http://services.xmethods.net/soap/urn:xmethods-delayed-quotes.wsdl");
// create service
Service service = factory.createService(wsdlLocation, serviceName);
// create call Call call = service.createCall(portName, operationName);
My question on this...if I have a dynamic approach like the above what are the
pros and cons..I guess it would surely have more overhead compared to a static
client...?
Secondly ,is it even feasible to design a dynamic client in such a way that the
endpoint WSDL could also be an unknown and my generic client would also locate
the end-point dynamically and then invoke dynamic calls as above...
If anybody can share their insights on a dynamic webservice client , I would really
appreciate it...

Hi Krish,
In WSDL, the data types passed between applications are described in schema
and
this is key for interop. I dont know of any standard/natural mapping for
values types,
object reference, etc in a binary protocol (like JRMP, IIOP) to schema. For
eg:
say there is serializable object Foo, which is the argument to a remote
method in RMI.
Object Foo can have data + behavior. It may be possible (not always, i
think) to
describe the data in Foo as schema, but how can one describe the behavior?
So, if WSDL is the only contract between the server and client (key
requirement
for interop), then IMHO RMI can not be described by WSDL.
Also, WSDL was designed for future extensions and does not map well to a
programming API. WSIF trys to expose all the gory WSDL details and its apis
are very clumsy.
These were the two main reason to vote it down at JAX-RPC EC.
I am attaching an example that shows, how to introspect WSDL and invoke
a method using JAX-RPC (with little extension to the std api). Also, it
shows
how to handle complex type without data binding. Will this solve your
problem?
I am very interested to get your feedback on this.
BTW, This example will only work with WLS 8.1.

Mike...thanx for the inputs...
As per ur suggestion...I have taken this offline and mailed u [email protected]
also....lemme know if thatz cool...
there are my observations..lemme know what am i missing..
1) The main difference I see between JAX-RPC and WSIF, is that with WSIFclient
it is easier to port to services talking
via other ports like RMI,IIOP etc...where as JAX-RPC is understandsonly SOAP(atleast
for now).
2) Lets assume for the time-being that I would be interested only to talkto services
talking SOAP.
Then why do I need WSIF ?
3) I can have a JX-RPC client , I can have a similar generic(reflection)code
for built-in/primitive datatypes and for
complex datatypes I anywayz would be doing the same thing(requiringthe java
representation of the datatype unless I use
something like JROM or something which I do not want to) in JAX-RPC orWSIF.
>
4) As far as syncronous or asyncronous invocation is concerned , myunderstanding
is that my client call is going to remain the
same ..the service provider is going to either use message-oriented orRPC
on his side...
Again assuming that I am interested only with services talking SOAP, thiscould
be my generic client invocation design
Background is that my client is going to run from within a WLS70sp1
Actors:
a) webSevice1ClientSessionBean : This will be a stateless session beanwhich might
have knowledge about webSevice1's end-point ,
complex dataTypes if any.
(There would be other session beans like this which would haveknowledge about
other specific webservice)
b) GenericWebServiceInvoker : This will have knowledge about everythingwithin
the webservice-standards/protocols.
eg:
//set weblogic ServiceFactory
System.setProperty( "javax.xml.rpc.ServiceFactory",
"weblogic.webservice.core.rpc.ServiceFactoryImpl" );
//create service factory
ServiceFactory factory = ServiceFactory.newInstance();
//define qnames
String targetNamespace = "http://soapinterop.org/";
QName serviceName = new QName( targetNamespace, "SimpleTest" );
QName portName = new QName( targetNamespace, "SimpleTestSoap" );
QName operationName = new QName( "http://soapinterop.org/",
"echoStruct" );
//create service
Service service = factory.createService( serviceName );
TypeMappingRegistry registry = service.getTypeMappingRegistry();
TypeMapping mapping = registry.getTypeMapping(
SOAPConstants.URI_NS_SOAP_ENCODING );
mapping.register( SOAPElement.class,
new QName( "http://soapinterop.org/xsd", "SOAPStruct" ),
new SOAPElementCodec(),
new SOAPElementCodec() );
//create call
Call call = service.createCall();
//set port and operation name
call.setPortTypeName( portName );
call.setOperationName( operationName );
call.addParameter( "inputStruct",
new QName( "http://soapinterop.org/xsd", "SOAPStruct" ),
ParameterMode.IN);
All parameter values specific to a particular webservice likeQName,targetNameSpace
etc will be sent to this invoker by
webSevice1ClientSessionBean. The GenericWebServiceInvoker will invokethe
service
(using reflection for primitive/builtin types) and alwayz accept anobject
from the service operation and just return
that "object" back the webSevice1ClientSessionBean.ThewebSevice1ClientSessionBean
will know how to interpret the
complexdataType or builtInDatatype whichever is returned.TheGenericWebServiceInvoker
will not have any application
specific knowledge...it will just have knowledge about how todiscover, invoke
any SOAP webservice...
Somewhere in the beginning of GenericWebServiceInvoker I will use JAXRto
discover services from UDDI if needed.
This way I will have a generic webservice client invocation frameworkwhich
can invoke any service which talks SOAP.
Now lemme know how the above picture looks and what is missing...
I have some questions :
1) Incase of complex dataTypes, I will have itz XML representation inthe
publisher's WSDL and the publisher will give
me the java representation of the complex dataType.But how does myclient
JAX-RPC know how to map the XML
to the java representation unless I specify the mapping somewhere?Does
the TypeMapping/TypeMappingRegistry do this ?

You know, it's really cool to hear guys thinking things through, before
they "jump
on a bandwagon" :-)
Anyway, I suspect that the performance overhead of doing reflection,
and heavy
server-side code intrusion, is what has made a lot of developers balk
at using
WSIF. I would check out the IBM newsgroups, to see what the general
developer
sentiment is on WSIF.
To achieve any sort of decent performance with JAX-RPC based webservices,
you
need to do a fair amount of optimization/tuning on both the client and
server
side. I recommend setting up your own "lab environment" for doing these,
so you
can see exactly what's making things improve/degrade. If you are really
interested
in this topic, we should talk about it "off-line".
In general, the more "dynamic" things are on the client side, the slower
things
will be, the more you really need to question if you really need them
to be dynamic
:-) Does making it "dynamic" really offer something that you can't get
from a
"static" version? If not, who's really benefiting here. I mean, com'n.
All you
really want to do is invoke an operation, right? By the time you get
all the information
it takes to do a dynamic invocation (i.e. port, target namespace, data
type for
input argument, serializer/deserializer for each non-built-in data type,
etc.),
your client looks like you are trying to boot a PDP-11! LOL! For those
of you
who don't know what a PDP-11 is, it's an early computer (from the'60-'70),
that
you actually had to use switches to create the "binary instructions"
to boot it
up!
From a PM's (product manager's) perpective, I wouldn't even let thedevelopers
modify "working" EJBs to expose them as a web service. Alarm bells should
go off
in your head, if you have to modify existing server-side code to expose
a company
asset as a web service.
Response to OT comment: WebLogic Server 7.0 uses its own implementation
of JAX-RPC
1.0. This implementation, I've been told by one of the BEA engineering
that worked
on it, has been certified to be JAX-RPC compliant by Sun. Don't know
about Apache
Axis, in this regard. I use both Apache Axis and the JWSDP with WLS 6.1,
but I
haven't really spent a lot of time looking for differences between our
(BEA's)
implementation, and theirs.

U mite have a better hold of what WSIF can do...whatever I could grasp
from yesterday
is this...
a)It reads meta data from the wsdl and using a reflection mechanismcalls
the
service operations...
I see examples with primitive datatypes..but what happens when
complex/custom
datatypes come into play...
Would the client code differ between synchronous invocation toasynchronous
invocation...
And aleast in the samples for the WSIF distribution for connectors like
EJB/JMS
etc, the code does not look generic anymore..there are specific calls
to operations
and parameters...
Also Mike , what is the trade-off on performance between having adynamic
client(lets
say based on WSIF)or having a static client...the extent of reflection
a dynamic
client will have to do and create SAAJ objects at runtime will beenormous..
Also I know that there is a relevant API...but can u give an examleshowing

how I could discover services from UDDI ..?
Out of this current topic...does BEA use itz own implementation of SOAP

Hi Krish,
Well, I guess that's how things are when "needed functionality exceeds
the current
state of a technology" :-)
I (not necessarily BEA) look at it like way:
1. IBM co-authored the "Big 3" XML grammars for the current web
services
stack.
2. IBM always appears to be "there, somewhere" in the new crop ofproposed
additional
XML grammars for "partially agreed upon extension layers", for theweb
services
stack.
3. IBM donated it's original SOAP implementation to the open-sourcecommunity.
4. IBM came up with WSIF over a year ago.
5. IBM's WSTK uses the Apache Axis stuff.
6. A lot of the JAX-RPC/JAXM API is based on the Apache SOAP and Apache
Axis implementations.
7. It looks like IBM may have donated WSIF to Axis.
8. You appear to need something like WSIF :-)
So, there's probably at least a 60/40 chance that some WSIF-like thing
will make
it into the JWSDP, right? If you want "higher odds", you should talk
to the folks
working on the JWSDP, as they are somewhat "in charge" here :-)

Correct?
This is a relatively new "unofficial" addition to the Web ServicesStack,
so it
is not in WLS 7.0 (or Sun's JWSDP) yet. See the following link formore

Some DB objects like User-defined datatypes being missed out?

Dear all.
I create an Oracle model for a captured SQL Server model and then right click -> click on 'Generate' to create the DB creation script.
(1) But few objects like user-defined datatypes are missed out in the script.
(2) Also, a simple stored proc as defined below missed out:
CREATE PROCEDURE [SalesLT].[SayHi]
AS
SELECT 'Hi I am a job scheduler'
GO
Rgds, Abhi

Hello,
An OracleDI Dataserver connection to an RDBMS is, most of the time, defined with a single set of parameters: a user account name, a password and a URL.
OracleDI may need to access numerous tables on the RDBMS which may not all be stored in the same database schema, catalog, library, ...and for which access privileges may not be identical.
For this reason, it is necessary to ensure that the RDBMS user account has sufficient access privileges for these schema, catalog, librairies ...
The user account should have at least read/right access permission for any OracleDI Physical Schema referenced for the concerned Dataserver (depending on the project within which it is used, a Physical Schema may store both source and/or target tables).
Moreover, for project requirements, it may be necessary to use/create/drop certain RDBMS
components such as stored procedures, views, temporary tables, system tables ...
For this reason, make sure the user account referenced in the dataserver connection parameters is attributed sufficient privileges to any object it may manipulate with OracleDI.
2nd point: you can use any logical name for the data server Name.

User Defined datatypes

Hello,
Is there any way we can make user defined datatypes in oracle as we do in Microsoft SQL / Sybase ASE.
I tried using Abstract TYPE but using it changes the Select query. I need to migrate some Sybase code to Oracle and also need to implement the user defined datatypes for tables.
Any clue on as to how I can create this in oracle.
Regards
Suchetan

Thanks for your replies.
Here is how we use UDD in sybase and also how the queries change when TYPE is used in Oracle.
Eg:-
***************** Sybase **************************

go

(return status = 0)
create table TEST
usrname name10)
go
sp_help TEST

Object_type
TEST dbo
user table
(1 row affected)
Data_located_on_segment When_created
default Jan 17 2007 9:43AM
Column_name Type Length Prec Scale Nulls Default_name
Rule_name Access_Rule_name Identity
usrname name10 10 NULL NULL 0 NULL
NULL NULL 0
(return status = 0)
INSERT INTO TEST VALUES('SUC') /* Insert is like any table created without
UDD */
GO
(1 row affected)
SELECT usrname FROM TEST
GO
usrname
SUC
(1 row affected)
******************************** Sybase End ***********************
********************** ORACLE *******************************

User Defined datatypes dont work

URGENT HELP REQUIRED! SOS!
I had installed PO 8.0 on one of my machines, but when tried to create user defined datatypes, it says 'Object Type Not Enabled'. Does that mean we can ENABLE creation of user defined datatypes in PO 8.0? If so, please guide as to where i can find this option.
Secondly, when I install Oracle 8.1.6 and forms6i on my Server (windows NT environment), I find that although tyopes can be defined in sql8.0, the same is shown as UNDEFINED in sql3.3. Is it a bug or am i missing out something? Please guide.

Crystal Report Templates for User-Defined Objects

Hello Experts,
I am running SAP B1 8.8 PL11. In the current patch SAP has default Crystal Reports that can be used as Layouts for Invoices, Credit Memo's so on. Is it possbile to have layouts for user defined objects ( say for instance i have a customized form under sales module, can i import a crystal template for this customized form?). In the report layout manager i don't see an option to import user-defind objects.
Any help would be appreciated.
Thanks,

If this is still a problem please re-post to the SAP Integration Kit forum.

Standard report for User defined feild in order operation

Hi all,
do we have any standard report? for User defined field in order operation. actually we have User defined field in task list and same could be reflected in order operation. so i am using those user defied field to record extra info in maintenance order. i am wondering how to get the reports . do we have any standard reports?
thanks
Amit kushwaha

Dear Amit
I have utilised 3 user fields & activated order enhancement tab. I could find these three fields in report IW37N & IW49N. I m using ECC 6.0 EHP4. Try to set the layout & look for fields - user field for quantity in the layout. For this please maintain some data in these user fields of some orders and then check for those orders in t code- IW37N & IW49n.

Batch Input for user defined fields (SRM 4.0)

Hello.
Now in my project,we are developping Batch Input function about PO,CONF in SRM 4.0.
and in this time, we will use over 20 user defined fields.so we have to enter the value to user defined fields by using Batch Input function.
But if we will enter over the 10 value for user defined fields,we have to scroll the screen.
How do I scroll in SRM?(What's the command to scroll in SRM)

What is the Object Type for User Define table ?

Dear All Experts,
I create one of the User Define Table with no. of UDF's
I already register User Define Table with Unique ID.
As per my knowledge, Unique ID is our Object type for that User Define Table.
I want to add Transaction Notification Code for created Used Define Table.
This Transaction Notification prevents user to must enter name in that form.
IF (@object_type = 'Z_Roto' AND (@TRANSACTION_TYPE = 'A' or @TRANSACTION_TYPE = 'U'))
BEGIN
If not Exists (Select T0.DocEntry from [@Z_ROTO] T0 Where ( T0.Name is null OR T0.Name = ' ' ) AND T0.Code = @list_of_cols_val_tab_del )
begin
SET @error = 1
SET @error_message = 'Name is NULL then So, Please enter ZERO Value i.e. 0 in Filed_Name'
End
End
Please help me for this problem.
Thanks & Regards,
Nishit Makadia

Hi All,
Thanks for your replay.
Below code is working for User Define Table's Transaction Notification
IF (@transaction_type = 'A' OR @transaction_type = 'U') AND @object_type = 'Z_Roto'
BEGIN
If Exists (Select T0.Code from [@Z_ROTO] T0 Where ( T0.Name is null OR T0.Name = ' ' ) AND T0.Code = @list_of_cols_val_tab_del)
begin
select @error = 10
select @error_message = 'Name is NULL then So, Please enter ZERO Value i.e. 0 in Filed_Name'
End
End
Necessary to Remember 4 Things. That are mentioned below.
1) Register User Define Table (UDT) with using "Object Registration Wizard". For Example : @object_type = 'Z_Roto'
2) When you define selection criteria then it must be compulsory for use Code Field. For Example : Select T0.Code from [@Z_Roto]
3) When you define selection criteria then it must be compulsory for use Code for @list_of_cols_val_tab_del.
4) Use error code as 10 Number
Thanks & Regards,

Is there a range of error codes reserved for user defined error codes?

I would like to create my own error codes for a CVI dll but I want to make sure I don't use error codes already defined for something else. Is there a range reserved for such use?
Samee thing for warnings (errorcode > 0)
Thanks

I have never found a positive mention of a "safe" range of error codes available for user-defined error conditions, but I can suggest you some source of informations.
First of all, every library has its specific list of error codes, usually listed in the relative include file. All these error codes are listed in the online help too (search for "error codes" in the index tab of the help).
Second, GetGeneralErrorString () is a function that can be used to trap errors of the following libraries with a unique error function:

Easy I/O instrument driver
Toolbox instrument driver
ActiveX Library
DIAdem Connectivity Library
.NET Library
DataSocket instrument driver
Network Variable Library
Real-Time Utility Library
TDM Streaming Library
UDP Support Library
This means that the error codes from this libraries do not overlap, so you could derive from its code some ranges not used by these libraries.
Nevertheless, there is not a single function for error trapping: every library has its proper list of error codes and a function to decode them in human readable form, andthere is no guarantee that these ranges does not overlap. It's up to you to trap errors from every function in the proper way.

Class Data Sharing for User Defined Classes

i am using jdk 5.0 . JDK 5.0 supports class data sharing for system level classes. Is there any way a class data sharing be done for a user defined class?

Is this class data sharing possible for user defined classes also? i have a singleton class which i am invoking through a script. The script has been scheduled to run every 1 sec . Since it is being invoked every 1 sec hence the singleton pattern is failing . Hence if the this class data sharing is possible then the singleton pattern can be made applicable.If you have a single process and you have a single class loaded by two different ClassLoader instances
in some respects they will be two different classes
if (class1 instanceof class2.getClass())returns false.
This is not the case for Java core classes because they are always loaded by the SystemClassLoader.
You write you

I am trying to figure out if you launch a new JVM every second...
Maybe you can use Nailgun.
