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).

Value type and 500 Internal Server Error (SOAP)

Hi,
I'm try to generate, by jdeveloper10g, an Oracle J2EE WebService, on an Oracle Application Server 10g.
One method that i want to publish as web service should return a class, DBVarWS, created by me. This class has a public default constructor, every private fields has its get and set methods, and so on. Jdeveloper creates and deploys the WS without problem. The other methods of the ws work, but this one generate an Error 500:

Unexpected value type for Item Tag Name ; expected System.Single, received

Hi,
I am using PCo 2.1 with MII 12.1 to extract values from some PI tags. When I run the query, I get this error -
Unexpected value type for Item <Tag Name>; expected System.Single, received System.String[Value = Scan Off]
Can somebody explain what I need to do to get the correct result?
Regards,
Chanti.

To make the service return "whatever is passed", you have to take a step back and realize that there is a little understanding of XML Schema required.
When using a complexType, which is defined as a sequence, then you are implying an ordered sequence of elements. Default value for the 'minOccurs' attribute is 1. It's also important to understand that there is a difference between minOccurs=0 and nillable="true".
nillable="true" just means that the name element can carry a null value. If you want the name element to be optional, then you must use the minOccurs=0 and keep the maxOccurs to it's default value of 1. Using an array is just a bad work around. This is for deserialization (XML to JAVA).
The second part of you problem is on the serialization (or JAVA to XML). When you have a JAVA Bean, there is no way to make the difference between a member's value being null or not set, so it's impossible to decide if you need to send back a nul (xsi:nil="true"), an empty element <ns1:name/> or nothing.
That said, if you do want to go the XML route, you can use the dataBinding="false" flag in the different WSA command. Instead of converting XML into JAVA, you will have SOAPElement parameters, where you can do all you want (see WS user's guide [1] for details - chapter 16). Note that you have to make sure that the WSDL (your contract) reflect what you are doing on the wire (format of your messages), so that you do not geopardize your interoperability with other toolkit.
Note that this only applies to literal message formats (use attribute in WSDL), which is your case.
Hope this helps,

Java.sql.Types.CLOB not returned

When I run the following on an oracle 8.1.7 server using thin/OCI driver on a table with a CLOB column,
DatabaseMetaData dbmd = conn.getMetaData();
ResultSet rs = dbmd.getColumns( null, null, tableName, "%" );
while (rs.next()){
int colType = (int)rs.getShort(5);
I dont get java.sql.Types.CLOB returned in colType, instead I get java.sql.Types.OTHER.
However, after a query on the same table, the result set metadata.getColumnType() returns java.sql.Types.CLOB.
Any ideas?
Thanks in advance

You can't do that. You can't do it in SQL either: there's no way to call a stored procedure without providing parameters of a specific type.
There are two things you can do, however: one is to declare the parameter as VARCHAR and hope it's not a BLOB or something that the db will not automatically convert to VARCHAR and the other is to do a SELECT in the procedure you are calling instead of returning the value as an output parameter. The second option is better in that you can then use ResultSet.getObject() from Java and obtain the correct object type, not a String you might need to parse afterwards.

Getting value type at runtime

Hello everyone,
I am using Scanner to get tokens from a buffer. I need to know the type (class) of the value returned. Instead of using "if" statement and hasNext?() for each possible type, is there a method that just return the type. Something like:
Class c = get(String s);So, if s is "Address", c would be set to String.class. If s is "true", c would be set to Boolean.class... etc
Thank you

Yeh, I just saw your other post:
http://forum.java.sun.com/thread.jspa?threadID=783200
The two topics are different but related. The topic, you refer to, are taking about getting a value. In that topic I need a method like:
Object o = String.toObject (String s, Class c);However, the topic "Getting value type at runtime" are taking about getting a type. In this topic I need a method like:
Class c = string.getClass();to return the type this string represents.

Build web service with value types

Hi,
I am trying to build a web service that uses a value type as a parameter.
I am using wscompile and wsdeploy to build the service.
But I don't know how to include the value type in my service.
This is what I do:
First I compile all the java files and put them in my build directory (incuding the value type class)
Then I use wscompile -define -d build -nd build -classpath build config-interface.xml -model build/model.gz
Then I create the war file that contains the class files, model.gz, web.xml and jaxrpc-ri.xml.
Then I run wsdeploy -o dist/generic-serv.war dist/generic-service.war
How do I get my value type class included in the wsdl file? and does it need to be in the model.gz file aswell?

Sorry I was a bit wrong describing my problem.
I am trying to use an ArrayList containing value types as a parameter.

Re: Custom Value Type

I have sort of answered my own question. I found, under the heading:
"Storing Second Class Objects via Stringification", that you can use
externalizer and factory extensions. However, what if I want to externalize
to, say, a java.sql.Date (mysql's date column). For example, suppose I have
my own Date class? How would I handle that?

Dave,
You've got a couple options for storing custom SCOs (second-class
objects). The stringification route is useful when you can encode the
custom field type as a string -- java.net.URL, for example.
For storing data in non-String fields, you'll want to create a custom
field mapping. See the timestampField sample in the samples/ directory.

Help on java.sql.Types class

Hai Friends ,
I want some help on java.sql.Types class .
What is the use of the above class ?
Some details about this class.

Good Morning Yekesa
First of all i would like to thank U for looking into my problem.
I am using java.sql.Types.OTHER for
{"?=CALL(storedprocedurename.functionname(?))"}
registerOutParameter(1,javal.sql.Types.OTHER)
setString(2,"user")
here the
second parameter passes an argument to function name ( viz. username say "user")
and the function will return the ref cursor as follows:
// declaration in pl/sql procedure
begin
rc ref cursor
open rc for select * from ss_user where login_name="user";
return rc;
end
now the stored procedure has a return value (i.e. stored function) which it needs to register as
registerOutParameter(1,javal.sql.Types.OTHER)
and it finally results in the following errors :
Loading driver
Before conn stmt
After conn stmt
Calling Stored procedure
Stored procedure called
java.sql.SQLException: Invalid column type
at oracle.jdbc.dbaccess.DBError.check_error(DBError.java:243)

at oracle.jdbc.driver.OracleCallableStatement.registerOutParameter(OracleCallableStatement.java:54)
at sptest.<init>(sptest.java:28)
at sptest.main(sptest.java:49)
T couldn't understand why it is saying Invalid Column Type because its working fine with both
java.sql.Types.INTEGER
and
java.sql.Types.VARCHAR
Pl help me at the earliest as i have wasted a lot of time on it.

What is Oracle Java Class Type?

Hi,
I read a oaf coding stand document.it said that "Can not use database Java(Oracle Java Class Type)".do anyone know what is Oracle Java Class Type?
Thanks & Regards
binghao

Are you using the internal converer?
<af:inputText value="#{bindings.MyClobContent.inputValue}"
label="#{bindings.MyClobContent.hints.label}"
converter="oracle.genericDomain"
required="#{bindings.MyClobContent.hints.mandatory}"
columns="#{bindings.MyClobContent.hints.displayWidth}"
maximumLength="#{bindings.MyClobContent.hints.precision}"
shortDesc="#{bindings.MyClobContent.hints.tooltip}"
id="it2" rows="10">
<f:validator binding="#{bindings.MyClobContent.validator}"/>
</af:inputText>
If it does not work, create & use custom converters as mentioned in the above thread.

Expected value type: end-of-string infopath configuing the main submit button on the form.

Hi Everyone,
so I have run into this very odd problem. When I am trying to configure my main submit for my infopath 2010 form, and it says File Name, I put in concat(field 1, field 2, field 3), and when the form submits, I get the following as a name for my form: field
1, field 2, field 3, exactly like that. so I went back into the main submit and typed concat( and then used the function button, which brought up the list of controls to choose from, so I choose field 1, field 2, field 3 and when I hit ok, I keep getting this
error:
Expected value type: end-of-string
Actual value: ,
my:secReqMetaData/my:field 1-->,<-- my:secReqMetaData/my:field 2,my:secReqMetaData/my:field 3
does anyone have any idea why this is happening?
Best regards, Mike

Thanks for sharing the answer here, it would be helpful for others with similar issue.

A list of values type item in a based table block

My block is based on a table. An item of the block take the value of a field of the table when the form raises. But this item must be updateable (by selecting a value in a list) and then it must be of the list of value type. And the values in the list of values come from another table (not the based table). Is it possible ? If it is, how can I do this ?
Thank you !

Yes, it's possible. Just use a regular text item. Create an LOV using the LOV wizard. When you define the query for the LOV's record group, enter a statement that selects from the other database table. Set the return value of the appropriate LOV column to be the text item on the form. Finally, assign the LOV to that text item, so that the LOV pops up when the user presses the LOV key with the cursor in that text item. You can also set the LOV so that it automatically displays when the cursor enters the text item.
Just look up LOV in online help if you need more info.

Value Type and Report Type in Report Painter Report

Is there a way I can get both characteristics WRTPP and RRCTY in one table? Or, can I work with two different tables in creating Report Painter report? I need to get the planned values of cost elements with record type 1 and value type 10 to show under one column in my report.
Your help is very much appreciated.
Edited by: Mauricio Villa on Oct 23, 2010 10:32 PM

use the selection criteria to restrict the field types in the query designer- use other variables to check the value
if it doesnt reconcile- you can alternatively use a multi provider for the same thing- that way you will get the same amount in 1 column and you could restrict using the infoprovider column

WRONG QUESTION

Statistical cost element (Value type 11) line item entry in CJI3

Dear all
I am doing WBS settlement to AUC thr CJ88. Suppose actual cost on WBS is 100 rs.
CJI3 report shows the balance to be settled to AUC. Now It is showing 100 rs balance. I carry out WBS settlement to AUC.
Even though settlement has taken place to AUC, CJI3 is showing line item entry of 100 rs (Statistical cost element with value type 11).
This also affects our reporting as in report S_ALR_87013558, because of statistical cost element line item entry, WBS actual cost is showing as (100+100 st'cal)
Also, I read in sap note 666152 that we can define transaction type as not releavent for account assignment. But i dont see this kind of setting anywhere in transaction type.
Can we restrict the statistical cost element to not take part in CJI3 (CO reporting)? How we can avoid statistical CO postings.
Pls suggest
Madhusudan Patil

Hello,
Statistical postings could be generated, if
(a) you have 2 co-objects, e.g. cost center and internal order. There is a default rule in the system, that in this case the internal order will be posted real and the cost center statistical
(b) you have 2 co-objects and one is marked as statistical in the master data. Actual Postings only to statistical co-objects are not possible. You can not settle statistical values, they will stay at the object.
Please check OSS-message 106968. It explains everything in detail.
You can modify your report, that it will show only real postings (value type 04), but I wouldn't do it. For me it sounds that you have to check your value flows in general. They look inconsistent, if you do not expect statistical postings.
Kind regards
Tapio
