Java Type mapping of NUMBER columns

I'm using JDBC Oracle driver 10.2.0.4, with java 1.5 and Oracle 10.2.0.4.
Reading a field of NUMBER(6) JDBC driver map it to java.lang.Integer, if I extend this column to NUMBER(9) Jdbc map it to java.lang.Long.
When can I find a detailed documentation of Number mapping, i found some documentation for general field mapping but is not exhaustive about NUMBER fields and this behavior is not documented.
Thanks
Carlo

That is all database/driver specific. So you have figure it out using what is in the Oracle java classes. There is no generic jdbc solution. If you are lucky the Oracle docs for the driver might document something useful.
If it was me I would just wrap another proc around it and have that strip the fields out for me and return it as a regular result set.

Attachment to Java type mapping

I want to create a web services to receive quite big portion of information. So I defined my method as:
@WebService
public class Infolet {
    public long run(String name, String enterprise, InputStream instream) throws RunException {
      printStreamContent(instream);
      return 1;
    }wsgen creates wsdl with abstract class InpputStream, so obviousy I can't use a real input stream in my client code matching to this parameter. So what's solution?

Dave,
What docs are you looking at? http://docs.solarmetric.com/sql_types.html
seems to have the complete table.

The problem is, I didn't see any java types.
Where can I find a table that states the sql types that correspond to java

Toplink JPA and Java type mapping

Hi there,
I'm struggling wit mapping an existing database using Toplink Essentials.
Specifically: I have an INT SQL field which I want to map as boolean/Boolean in my entity class.
How to do this? Either in standard JPA or with some Toplink extensions?
Markus

Hi Markus,
The JPA spec doesn't cover conversion/transformation but you can do it with TopLink Essentials using a Converter. I have an example pasted below that uses a converter to map between a database VARCHAR value and a pre-Java 5 enum (i.e., a hand coded enum-type class that runs in Java 1.4).
I use a descriptor customizer to get hold of the Basic mapping (in TopLink a "DirectToFieldMapping") and then plug in a converter.
--Shaun
Persistence.xml:
<property
   name="toplink.descriptor.customizer.TypeWriter"
   value="oracle.toplink.essentials.emf.examples.library.orm.TypeWriterCustomizer"/>The customizer:
public class TypeWriterCustomizer implements DescriptorCustomizer {
      * Add customizer to translate between Enum and value.
     public void customize(ClassDescriptor descriptor) throws Exception {
          DirectToFieldMapping typeMapping = (DirectToFieldMapping) descriptor.getMappingForAttributeName("type");
          Converter typeWriterEnumConverter = TypeWriterEnumConverter.getInstance();
          typeMapping.setConverter(typeWriterEnumConverter);
}The actual converter class:
* TypeWriterEnumConverter is a singleton since it has no state.
public class TypeWriterEnumConverter implements Converter {
     protected static TypeWriterEnumConverter instance = new TypeWriterEnumConverter();
     private TypeWriterEnumConverter() {}
     public static TypeWriterEnumConverter getInstance() {
          return instance;
     public Object convertDataValueToObjectValue(Object data, Session session) {

          TWriterType type = (TWriterType) object;
          if (type != null) {
               return type.getName();
          } else {
               return null;

          return false;

BC4J Custom Type Maps (MS-SQL cont.)

(FYI using JDeveloper 9.0.2.0.0, MS-SQL 2000 spk2 and MS-SQL's JDBC driver Version 2.2.0022)
In the process of trying to get JDeveloper working fully with MS-SQL, I am at the point of developing a custom type map.
Should this typemap include all mappings or only those different than the "Java" or "Oracle" type map? I was assuming all at first. Now I wonder how it's handling missing mappings.
How does it find a matching typemap? I noticed that Entity's database column types looked like "int(10,0)" and "bit(1,0)", but in my typemap, like the examples, it's just "INT", "BIT" with no precision, scale. Is this a case of where it's assuming the driver will return a string for type and it's returning type(p,s)? Or is JDev building that string? Either way, would you need a different mapping for "bit(1,0)" than "bit"?
As "bit(1,0)" it had problems with both the Java map and my custom map. Changing it to "bit" seem to get it to work. So what typemapping was it trying to use as "bit(1,0)"?
[Bug?] I noticed that when I view the bc4j settings (project (rt-click) -> edit business components project), the value for type map is incorrect if I am using a custom type map. If I am using the Java type map it says "Java" in the greyed out select, but if I am using my custom map ("MS-SQL"), it says "Oracle". I checked the bc4j.xcfg for the one using my custom map and it does say the right class name for jbo.TypeMapEntries.
On a related note, when testing the bc4j modules, we are instructed to use the edited local configuration, but how do view/edit the project default configuration?

Data type mapping

Hi,
Where can I map the java datatype to its equivalent DB datatype. I think for Oracle, MS SQL server,Sysbase there is default type mapping.

Jagan wrote:
Great Joe,
Thanks for ur immediate response.:-)
I have few issues here :
1.) Tell me whether i can use Postgres with weblogic6.1 and above versions.Weblogic supports any JDBC driver to any DBMS, as long as the JDBC driver
implements the standard JDBC spec, and is threadsafe.
2.)Can i create tables using weblogic and Postgres?if yes,how?Surely, via the SQL commands Postgres understands, and JDBC:
statement.executeUpdate("create table myTable(myInt int, myName varchar(30), ...)");
3.)If no support is provided,please tell whether weblogic support only the four
Databases mentioned in the doc,explain clearly.BEA is totally devoted to the J2EE standards. We must support any driver and
DBMS that also meets the J2EE spec.
4.)Is there no way i can specify datatype mapping using the weblogic API also?
Application servers like JBoss provide us with a xml where we specify the datatype
mappings for each database,is there something like that for weblogic?no.
Else provide me with a solution.I'm not sure what your exact desire is. For a given DBMS there are a unique
set of column types. There is some overlap across DBMSes, and there is
usually some types that are unique to the DBMS, and some that are generic
in purpose, such as date-time values, that is implemented differently in each
DBMS.
For each DBMS there is one or more JDBC drivers. Each driver will convert
a given DBMS column type to any logically convertable JDBC type. Ie:
an integer column in the DBMS can be asked for via getString(), and the
driver will convert the value 123 to "123". Drivers will also decide what
JDBC type to create from a given DBMS column. If a column value is
asked for via getObject(), the driver will make what it thinks is the best
Java type to represent the column. There is a JDBC spec for this, but many
drivers diverge from the spec.
What do you need, and how can we help?
Once again thanks for ur response,expecting the same again.Sure.

You will have to check the driver documentation for each DBMS driver
you use. There are too many deviations from the
JDBC spec to rely on it. For instance if you create an Oracle tablewith
an int column, if you do a getObject() to fetch
it's value, the Oracle driver will provide a BigDecimal object.

Hi Joe,
I think there is a big misunderstanding after seeing your reply.
What i meant was :
I am actually porting an application to weblogic6.1 and Postgre databasewhich
deployed and executed succesfully using weblogic6.1 and Oracle.
Here i face the problem of Datatype mapping for Postgres.
What i wanted is,is there a file or xml in weblogic where i can specifythe datatype
mapping for each database?
If yes,where and how do i do that,explain me with a sample plaese.
Please do not be specific to any database,because i am porting thesame application
to many databases,so please answer me in
generic.
Thanks in Advance,

How can I map CHAR jdbc type to the char java type

Hi,
I would like to make all changes in the DB schema file and use source
generation tools as a process. Now I foound that JDBC integer type
corresponds to the Java int type. But having:
<column name="ACTIVATION_STATUS" type="char" not-null="true" size="1"/>
The generated class field is of String type:
class .... {
private String activationStatus;
What is the proper way to have it mapped to char type fixing schema file
only?
Thanks in advance,

The Java Extended for Oracle type map and the Oracle Domains type map handle numeric data differently. When you create a new application the default type map Java Extended for Oracle maps numeric data to the java.math.BigDecimal >class, which inherits from java.math.Number. The java.math.BigDecimal default matches the way the Fusion web application view layer, consisting of ADF Faces components, preserves alignment of numeric data (such as numeric values >displayed by ADF Faces input fields in a web page). Whereas the Oracle Domains type map, which maps numeric data to the oracle.jbo.domain.Number class, may not display the data with the alignment expected by certain ADF Faces >components. Aside from this alignment issue, the Oracle Domains type map remains a valid choice and applications without ADF Faces components will function without issue.Thanks,

Number field type mapped as String

Oracle Number field is mapped as CSTRING when using CRECORDSET class in VC++.
Any ideas why? or what I should do?

How big is the number column defined? ANything larger than a NUMBER(14) will map to a character string since there isn't a datatype large enough to hold say a NUMBER(30).
Here is the mapping as I rememeber it (it is old information and may not be quite up to date with the latest drivers):
if Scale = 0 then if Precision <= 4 then
Number Size: Integer
if Precision <= 9 then Number Size: Long
Integer
if Precision <= 15 then Number Size: Double
if Scale > 0 then if Precision <= 15 then
Number Size: Double
Any other field types mapped to Text (Field
Size = 255).

The JNI defines a mapping of Java types and native (C/C++) types.

As per the tutorial
The JNI defines a mapping of Java types and native (C/C++) types.Does the above sentence mean that I can use dll written in C/C++ only and not dll written in Pearl.
Could anyone please give me the solution.

Please do tell me how can I call a dll file created in Perl ....And I will point out again that I doubt that it is possible to create a dll that has the following characteristics
1. Is in fact a dll.
2. Is in fact intended to run anywhere outside of the perl engine.
Step 2 means that you run perl, not a "perl dll" via C.
You can do that or at least in the past you could. And that has nothing to do with java nor JNI. So you would learn about it on a perl site.
And I can only note that when I did that a number of years ago it was very difficult. Certainly much harder than getting JNI to work. And you had better have quite a bit of C/C++ experience before you attempt it.

JPA - Columns to java.util.Map

I need to map the columns of a DB table into a java.util.Map object.
Any idea about how to implement this feature?
These are the columns of my table:
| ID | Value01 | Value02 | Value03 | ... | ValueN |I'd like to obtain a bean like this:
public class MyBean {
private String ID;
private Map values;
}I thought I could extend java.util.Map and redefine the get(Object) and put(Object, Object) methods
(I did something like this in java 1.4) but I can't figure it out in 1.5 with JPA

hi i have the following method,when i click my button am geting this error java.lang.String cannot be cast to java.util.Map

And that is correct - you can't do that cast. Which is what this code is trying to do.

(Map)actionEvent.getComponent().getAttributes().get("test")
>
Ask yourself what object is supposed to be the 'Map' in that line of code?
Is it 'actionEvent', 'getComponent()' or 'getAttributes()'?
My guess is that it is the 'getAttributes' that returns a map. Which means you need to cast
actionEvent.getComponent().getAttributes()as a Map. Which means you need to put that entire thing in parentheses so that the cast is performed on it. And then you have to put THAT entire thing in parentheses so you can call the 'get' method on it.
So this is the 'Map'
(Map) (actionEvent.getComponent().getAttributes())And this calls the Maps 'get' method
( (Map) (actionEvent.getComponent().getAttributes()) ).get("test")If you broke the line into pieces and stored each piece in its own variable you would see it. These object types may not be right but should give you the idea.
//( (Map) (actionEvent.getComponent().getAttributes()).get("test") ).get("test")
MyComponent myComponent = (MyComponent) actionEvent.getComponent();
Map myMap = (Map) myComponent.getAttributes();
myMap.get("test");

PL/SQL Evaluation problem of where clause in case of NUMBER column type

I found the following problem in Oracle® Database 2 Day Developer's Guide 11g Release 1 (11.1) B28843-04:
The sole parameter of function eval_frequency is employee_id IN employees.employee_id%TYPE.
An ORA-01422 exception occurs when the execution reaches the following select command
SELECT e.hire_date
INTO hire_date
FROM employees e
WHERE employee_id= e.employee_id;
A possible cause of the error is that the type of employee_id is NUMBER while the employees.employee_id is NUMBER(6,0) . The result of the selection is the same as there were no WHERE clause at all.
Everything worked fine, when I declared a temporary variable of NUMBER(6,0) for storing the actual parameter of function and used this variable in the where clause, but I consider this "solution" as being no solution.
It is pointless to use %TYPE parameter of a function for flexibility if I must degrade this flexibility by a fixed declaration of a temporary variable of the same type as the column in question.
What is wrong?
The Developer'Guide I used, the Oracle Sql Developer I used or the PL/SQL version ?

Hi,
Welcome to the forum!
user8949829 wrote:

The variable employee_id is defined as having the exact same type as the eponymous column. Even if it didn't, I believe Oracle will always implicity convert between datatypes when possible, rounding if necessary. That may cause errors, but it isn't causing this error.
No, the error has nothing to do with the data type. It has to do with the ambiguity of employee_id: is it a column, or is it a variable?
The default is that it means the column name, so
WHERE   employee_id = e.employee_idis equivalent to saying
WHERE   e.employee_id = e.employee_idwhich isn't quite the same thing as not having a WHERE clause; rows with NULL employee_id would still be excluded, if there were any.
I think it's best not to use variable names that are the same as column names. You could call the variable v_employee_id, or, since it's an IN-argument, in_employee_id.
If you must use a variable that can be mistaken for a column, then qulaify it with the name of the procedure, like this:
WHERE   eval_frequency.employee_id = e.employee_id
Everything worked fine, when I declared a temporary variable of NUMBER(6,0) for storing the actual parameter of function That makes sens. You probably gave that variable a name that couldn't be mistaken for a column in the table.

Make sure that you put the client jar file generated by

It looks like the runtime is unable to load

Mapping Java Types to XML Types

Hi, I have a small doubt in web services,
1) how a java data type can match with xml data type in wsdl,
2) how and where the java program can find the matching java
    data type to xml data type and vice versa
3) whether any mechanism is available for this data conversion?
4) where can i find that one?
Please advice me
Regards
Marimuthu.N

Hi Marimuthu.N,
My answers for your question, Kindly let me know if you need some more inputs.
+1) how a java data type can match with xml data type in wsdl,+
In SOAP 1.1 you have the following data types which is in XSD(XML Schema Definition), the same data type is also available in Java. For example (string, normalizedstring in xml is available as java.lang.String)
The complete list can be found in the table below.
XSD to Java Mapping.
XSD Type--------------------------------Java Type
base64Binary----------------------------byte[]
hexBinary---------------------------------byte[]
boolean------------------------------------Boolean
byte-----------------------------------------Byte
dateTime----------------------------------java.util.Calendar
date-----------------------------------------java.util.Calendar
time-----------------------------------------java.util.Calendar
decimal------------------------------------java.math.BigDecimal
double-------------------------------------Double
float-----------------------------------------Float
hexBinary---------------------------------byte[]
int--------------------------------------------Int
unsignedShort---------------------------Int
integer--------------------------------------java.math.BigInteger
long------------------------------------------Long
unsignedInt-------------------------------Long
QName-------------------------------------javax.xml.namespace.QName
short----------------------------------------Short
unsignedByte---------------------------Short
string---------------------------------------java.lang.String
anySimpleType-------------------------java.lang.String
+2) how and where the java program can find the matching java+
data type to xml data type and vice versa
Here is my WSDL which has a method getHello --> Pass Input as String --> Get Response as String.

         <wsdlsoap:address location="http://localhost:8080/TestWebService/services/Test"/>
      </wsdl:port>
   </wsdl:service>
</wsdl:definitions>I use apache axis for the client side code. I also suggest to start using this to get quickly into SOA(Service Oriented Architecture)
package com.googlepages.zackria;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import javax.xml.namespace.QName;
* TestClient for Webservice
* @author $author$Mohammed Zackria
* @version $Revision$1.00
public class TestClient {
     * main method
     * @param args pass nothing as far now
    public static void main(String[] args) {
        try {
            String endpoint = "http://localhost:8080/TestWebService/services/Test";
            Service service = new Service();
            Call call = (Call) service.createCall();
            call.setTargetEndpointAddress(new java.net.URL(endpoint));
            call.setOperationName(new QName("http://zackria.googlepages.com", "getHello"));
            //String Conversion
            String ret = (String) call.invoke(new Object[] { "Zack" });
            System.out.println("Sent 'Zack', got '" + ret + "'");
        } catch (Exception e) {
            System.err.println(e.toString());
}+3) whether any mechanism is available for this data conversion?+
Check the above code which has the following portion
//String Conversion
String ret = (String) call.invoke(new Object[] { "Zack" });
By default APACHE Axis returns Object Array which can be Casted to your WSDL defined data type.
+4) where can i find that one?+
[Eclipse Webservice|http://www.eclipse.org/webtools/jst/components/ws/1.5/tutorials/BottomUpWebService/BottomUpWebService.html]
Hope this helps out, Kindly Let me know if you need some more or if i have not answered your question.
Regards,
Zack

Java.util.Map type return in webservice method

Wonder, how we can return a java.util.Map type from a webservice deployed on a
weblogic 7.x environment..
any input is appreciated.

Thanks Michael. it helps.

Hi Girish,
By definition, a Java object used as a input parameter (or return type)
of a web
service operation, must has a no-arg constructor in order for a Java-based
Web
Service Stack to serialize/deserialize it to/from XML. java.util.Map
is an interface,
so it does not meet this requirement :-)
If your web service operation is just trying to return (or accept) a
hash map
of "arbitrary complex types", I recommend that you consider switching
this to
be an "array of arrays of specific complex types". The reason I say this
is because,
it allows even non-Java consumers to look at the <schema> elements in
your web
services' WSDL, and figure out all the possible "arbitrary complex types"
that
might be in this array. If you envision the consumer getting a box, where
it can
literally contain anything, you can probably see how much more code they
would
need to write, than if they knew the the box contained a box of these,
and a box
of these, and so on, and so on.
Basically, all the "old school" type-safety rules still apply to web
services
computing. If you want web services with descent performance metrics,
you're probably
going to want to keep a lot of the "old school, distributed computing"
practices
in mind, when you design your stuff :-)
That said, WLS 7.0 SP1 does not currently have a "built-in" HashMap codec.
But,
you could create one using the information at:
http://edocs.bea.com/wls/docs70/webserv/customdata.html#1054435
