Create bean from XML Schema

I am wondering if it is possible to create a bean from an XML Schema that I have defined in JDeveloper. In BEA Weblogic xml beans are automatically generated for you when you create a schema.
What I am trying to do is create a web service that has an input of an xml document based off the schema I have created. But I don't know how to specify that as an input.
Thanks.

Asking a similar question I was guided to TopLink 10.1.3 in this thread:
ADF Faces: Paginated Table backend (EA15)
I looked at XMLBeans but was surprised to find out that it does not generate JavaBean compliant javabeans which caused problems with JSF.
I have been using Castor, http://castor.exolab.org/, I don't know about it integrating with JDeveloper.
TopLink would be the most obvious choice if you need to integrate with JDeveloper. Keep in mind that it is TopLink's XML to JavaBean functionality is new but Oracle has been working with XML for a while. XMLBeans is also a young technology. Castor has been around for many years.
Good Luck,
Rachel

Create table from XML schema

HI,
is there any possibilty to create a relational table from a XML schema?

Can you use a schema when we compose XML doc from Database tables?
Actually, I'm using SQL Server (sorry, wrong forum). But, I thought a Java tool would have a solution for me.

Unable to create xml from xml schema

JDeveloper 10.1.3 EA1
I am unable to create a new xml file from an xml schema when the starting root element is a complex type (but it works with a simple type). It does not matter if the xml schema is registered within JDeveloper.
Is this a bug or intended behaviour?
Error message:
''XML Document from XML Schema creation could not be competed succesfully. Make sure the source schema is valid and that you have write permissions to the output directory."
NB The xml schema is valid and I have write permissions on the specified directory.

When I do not register this (or other) schema with JDeveloper, I can create an xml document from xml schema. However, when I register this schema and then try to generate an xml document (either from the registered xsd either from a filesystem xsd) with person as starting node it fails with the mentioned error. However, when I use city as starting node it is generated successfully.

Create xml from xml schema in java

An XML document may be created from an XML Schema with JAXB.

XML Document from XML Schema Bug

When an XML document is generated from an XML Schema the XML document does not have all the elements specified in the XML Schema. The XML document only has the root element.
1. Register an XML Schema.
2. Create an XML document with File>New>General>XML>XML Document from XML Schema. The "Generate only Required Elements" is unchecked.
3. The XML document has only the root element.
In JDeveloper 10.1.3 all the elements in the XML Schema get generated.

Also, the component palette for the XML document generated from the XML Schema does not list all the elements in the XML Schema, only the root element is listed. Even if elements are specified as required in the XML Schema with minOccurs="1" and the "Generate only Required Elements" checkbox is selected only the root element gets generated.

Java code to generate XML File from XML Schema

Hi I need this asap... "Java code to generate XML File from XML Schema i.e XML Schema Definition, XSD file".
Thankz in advance...

JAXB has been available as an early release download for some time. There are also XML Binding packages available from Borland (JBuilder) and Castor. These tools create Java classes from a source document, xml,dtd etc. You can use these classes to marshal-unmarshal XML documents.

How to identify objects created by registering xml schema

Hi Everyone,
We are using Oracle 9i Rel2. I have registered an XML schema and I saw that there were several objects created for it table ,some types and a trigger . For some build purposes I want to exclude all of these objects which are associated with xml schema and should be able to drop and recreate the whole of oracle schema.
I see the user_types table does not have any parameter to indicate that these are autogenerated or are different. In user_types they look like any other type that a user would have created. Do any of you know how to differentiate these types created by registering XML schemas from the normal types.
Thanks for your help

There is no way I know of to differentiate between a type created by Schema Registration and another Type. You can query the XML Schema itslef to get the Typenames it relies on.

Using "XML Document from XML Schema" in JDeveloper

Hi Experts,
I have a requirement to generate XML Document from XML Schema.
For this I have used "XML Document from XML Schema" feature in JDeveloper. It is found in File->New->General->XML Document form XML Schema.
I have registered a schema with jdev and got an XML document output for that successfully.
Now, I want to implement this feature in my code for generating XML documents when XSD files are provided.
Can any one please provide me with pointers to do that? I am sure there should be some libraries which can implement this feature.
Thanks,
Dilbagh

Create an XML document from a Schema with the Oracle SchemaClassGenerator.
import oracle.xml.classgen.SchemaClassGenerator;
XMLSchema schema=new XMLSchema();
XSDBuilder builder = new XSDBuilder();
URL url = new URL(schemaUrl);
schema = (XMLSchema)builder.build(url);
SchemaClassGenerator generator = new SchemaClassGenerator();
Generate the Java classes from the example XML Schema.
generator.generate(schema);With the java classes construct an XML document.

How to create our own XML Schema (.xsd) in Weblogic WorkShop

Hi,
I am new to Weblogic Workshop.I want to create one xml schema with custom elements.
when I am creating a file xml schema(.xsd).The file contains default namespace and no child elements in it.I don't know how to add elements to that file.
please tell me how to add parent elements and child elements and also our own xml namingspace.

Hi Sivaram,
Unfortunately, the 8.1 IDE did not have special tooling for schema generation.
You will need to create it by hand or using an external tool
If you are using an external tool to create the file within the schema project, you might want to disable the schema project auto build, which will be triggered every time a file save takes place

Creating entity beans (EJB3) from xml schema

Dear friends,
I have a XML schema.. and I want to implement an Enterprise application with EJB3 Entity Beans exposed through a set of JAX-WS Web-Services...
question: how to define the entities from the XML schema?

Two alternatives:
1) JAXB 2.0 generates POJOs with JAXB annotations in them. You can take ownership of those POJOs and add Java Persistence API annotations in them by hand. Basically, you will end up having both both JPA and JAXB annotations in the same Java class. You can then use them in your code both with JAXB APIs and JPA APIs.
2) Have a look at http://hyperjaxb3.dev.java.net/ It is trying to automate what I described in #1. The project is still not complete, so right now, you may have to hand code the JPA annotations.

SQL Server 2012 Management Studio:In the Database, how to print out or export the old 3 dbo Tables that were created manually and they have a relationship for 1 Parent table and 2 Child tables?How to handle this relationship in creating a new XML Schema?

Hi all,
Long time ago, I manually created a Database (APGriMMRP) and 3 Tables (dbo.Table_1_XYcoordinates, dbo.Table_2_Soil, and dbo.Table_3_Water) in my SQL Server 2012 Management Studio (SSMS2012). The dbo.Table_1_XYcoordinates has the following columns: file_id,
Pt_ID, X, Y, Z, sample_id, Boring. The dbo.Table_2_Soil has the following columns: Boring, sample_date, sample_id, Unit, Arsenic, Chromium, Lead. The dbo.Table_3_Water has the following columns: Boring, sample_date, sample_id, Unit, Benzene, Ethylbenzene,
Pyrene. The dbo.Table_1_XYcoordinates is a Parent Table. The dbo.Table_2_Soil and the dbo.Table_3_Water are 2 Child Tables. The sample_id is key link for the relationship between the Parent Table and the Child Tables.
Problem #1) How can I print out or export these 3 dbo Tables?
Problem #2) If I right-click on the dbo Table, I see "Start PowerShell" and click on it. I get the following error messages: Warning: Failed to load the 'SQLAS' extension: An exception occurred in SMO while trying to manage a service.
--> Failed to retrieve data for this request. --> Invalid class. Warning: Could not obtain SQL Server Service information. An attemp to connect to WMI on 'NAB-WK-02657306' failed with the following error: An exception occurred in SMO while trying
to manage a service. --> Failed to retrieve data for this request. --> Invalid class. .... PS SQLSERVER:\SQL\NAB-WK-02657306\SQLEXPRESS\Databases\APGriMMRP\Table_1_XYcoordinates>   What causes this set of error messages? How can
I get this problem fixed in my PC that is an end user of the Windows 7 LAN System? Note: I don't have the regular version of Microsoft Visual Studio 2012 in my PC. I just have the Microsoft 2012 Shell (Integrated) program in my PC.
Problem #3: I plan to create an XML Schema Collection in the "APGriMMRP" database for the Parent Table and the Child Tables. How can I handle the relationship between the Parent Table and the Child Table in the XML Schema Collection?
Problem #4: I plan to extract some results/data from the Parent Table and the Child Table by using XQuery. What kind of JOIN (Left or Right JOIN) should I use in the XQuerying?
Please kindly help, answer my questions, and advise me how to resolve these 4 problems.
Thanks in advance,
Scott Chang

In the future, I would recommend you to post your questions one by one, and to the appropriate forum. Of your questions it is really only #3 that fits into this forum. (And that is the one I will not answer, because I have worked very little with XSD.)
1) Not sure what you mean with "print" or "export", but when you right-click a database, you can select Tasks from the context menu and in this submenu you find "Export data".
2) I don't know why you get that error, but any particular reason you want to run PowerShell?
4) If you have tables, you query them with SQL, not XQuery. XQuery is when you query XML documents, but left and right joins are SQL things. There are no joins in XQuery.
As for left/right join, notice that these two are equivalent:
SELECT ...
FROM   a LEFT JOIN b ON a.col = b.col
SELECT ...
FROM   b RIGHT JOIN a ON a.col = b.col
But please never use RIGHT JOIN - it gives me a headache!
There is nothing that says that you should use any of the other. In fact, if you are returning rows from parent and child, I would expect an inner join, unless you want to cater for parents without children.
Here is an example where you can study the different join types and how they behave:
CREATE TABLE apple (a int    NOT NULL PRIMARY KEY,
b varchar(23) NOT NULL)
INSERT apple(a, b)
   VALUES(1, 'Granny Smith'),
   (2, 'Gloster'),
   (4, 'Ingrid-Marie'),
   (5, 'Milenga')
CREATE TABLE orange(c int NOT NULL PRIMARY KEY,
d varchar(23) NOT NULL)
INSERT orange(c, d)
   VALUES(1, 'Agent'),
   (3, 'Netherlands'),
   (4, 'Revolution')
SELECT a, b, c, d
FROM   apple
CROSS JOIN orange
SELECT a, b, c, d
FROM   apple
INNER JOIN orange ON apple.a = orange.c
SELECT a, b, c, d
FROM   apple
LEFT   OUTER JOIN orange ON apple.a = orange.c
SELECT a, b, c, d
FROM   apple
RIGHT OUTER JOIN orange ON apple.a = orange.c
SELECT a, b, c, d
FROM   apple
FULL OUTER JOIN orange ON apple.a = orange.c
go
DROP TABLE apple, orange

Pulling validation pattern from XML schema in LCD

Hi team,
We have deisgned a fillable PDF form uding Live Cycle Designer ES2.
The form contains fields of different data types.
We have created a data connection on the form (using LCD) to bind it to a XML Schema
The XML schema has different types of validations for different data types.
When we treid to bind the XML schema to PDF form using LCD, most of the validations were pulled in. Example, numeric lenghth check, string length check, minoccurs , maxoccurs
But few validations were not pulled from Schema like Pattern validations on string.
Please guide us on how to achieve this using LiveCycle Designer ES2.
Cheers,
Kavi

Hi Kavi,
The pattern from the XML Schema can not be automatically copied across, I assume because of the differences in the XML Schema pattern regex and a JavaScript regex. If you did use a compatible subset I you could write a macro to add the pattern to the validation event. One difference is a XML Schema pattern always assumes a ^ and $ to match the beginning and end. Have you seen this document http://partners.adobe.com/public/developer/en/livecycle/lc_designer_XML_schemas.pdf,
Regards
Bruce

How to create table for XML schema-based Interface form

Hi All,
With tcode SFP to crate a XML schema-based Interface form, how to create a defined table can be listed in "Data View"?
Just like APAP Dictonary- Based Interface form, that we can drag a defined table from data view to the panel.

Hi,
Just follow these steps:
1. Create interactive form UI element in your view.
2. Now provide Datasource and PDFSOURCE to it in form properties.
3. Now give a template name prefix with 'Z' or 'Y'.
4. Double click on it. It will prompt for interface name.
5. Provide interface name prefixed with 'Z' or 'Y'.
6. Click on Context button in the Pop up window and provide the node you have selected as DATASOURCE.
7. Click ok and it will open the form designer.
8. In this way you can create a XML Schema based Form.
9. Activate the interface and design the form providing layout type and other details.
Hope it will help.
Regards,
Vaibhav

Unable to disply type created by registering XML schema

Hello,
I have tried to register my XML schema.
The process returns with success and I can see new object types created by:
select * from user_types;
However, if I perform a DESC on the object type it says:
ORA-0403: object <MyType> does not exist.
Has anybody seen the problem before ?
Thanks,
Bryan

Hi,
Thanks a lot for the reply.
I have tried out and it seems to me that the SQLType specified in my schema must be in Capital letters. Otherwise DESC won't work.
Quoting it doesn't seem to work as well.
