XSD to java class

Anyone know an application that convert automatically a XSD file into a java class that can create and manipolate a XML file (based on my XSD)?
Thanks
MAuro

The best method is to install java web service pack JWSD. It contains XJC and JAXB which helps to create java classes from XSD and JAXB helps in processing that DOM in your java program which uses the JAXB library.JWSD also provides many other tools like JAXP,JAXR etc which helps you to solve all the problems in domain related to the XML.

Generate XSD from java class

Hi all,
Is there any tool that can generate an XSD from either a java code file or a byte code file?
Thanks in advance,
Asaf

I've never used it, but the Castor project also provides such a tool...at least that what it says in its FAQ:
http://www.castor.org/xml-faq.html#Is-there-a-way-to-automatically-create-an-XML-Schema-from-an-XML-instance?

Converting java classes to an XSD, is there a tool?

Or do I have to do this by hand. I was talking to someone who teaches this enterprise/webservice stuff and he said something to the effect that jaxb can convert my java classes to .xsd files, i don't see how this is possible (I see the other way, from .xsd to java classes). So did I just misunderstand him?

thanks, I think he misunderstood me. I had done the .xsd files already, and he said I did to much work and there is programs out there to build them for me. It all came up in conversation cause I was curious if I had even built my .xsd files (cause my resulting web service is running oders of magnitude slower than when running my same code not through the web service) so I had just assumed I wrote bad xsd, code, or whathave you.

How to create java classes when multiple xsd files with same root element

Hi,
I got below error

I tried genarate java classes from multiple xsd files, but getting above error, here in .xsd file i have the <xe: element="resultClass"> in all .xsd files.
So I removed all .xsd files accept one, now genarated java classes correctly. but i want to genarte the java classes with diffrent names with out changing .xsd
Can you please tell me any one how to resolve this one......

Gregory:
If you want to upload several Java classes in one script the solution is .sql file, for example:
set define ?
create or replace and compile java source named "my.Sleep" as
package my;
import java.lang.Thread;
public class Sleep {
public static void main(String []args) throws java.lang.InterruptedException {
if (args != null && args.length>0) {
int s = Integer.parseInt(args[0]);
Thread.sleep(s*1000);
} else
Thread.sleep(1000);
create or replace and compile java source named "my.App" as
package my;
public class App {
public static void main(String []args) throws java.lang.InterruptedException {
System.out.println(args[0]);
exit
Then the .sql file can be parsed using the SQLPlus, JDeveloper or SQLDeveloper tools.

About generating Java classes from XSD Schema ???

I need a powerfull tool to generate Java classes from XML Schema. I want that generated classes to have the option to validate XML(to be JAXP1.2 compliant).
I used XML Spy 5.4 but the generated classes can't validate an XML file.
Can you help me with other tools that:
- generate Java classes from XSD
- generate sample XML from XSD
- are JAXP1.2 compliant(validate a XML file with a schema)
Thanks.

You can also use Castor: http://www.castor.org
It generates classes from XML Schemas and enables data
binding without writing any line of a fuckin SAX
parser :-)I evaluated Castor and JAXB and while JAXB isn't perfect, it's got some things over Castor. Castor almost looks abandonded when I go to the site. The documentation just sort of trails off.

Error when generating Java Classes from XSD

I'm getting the following error when using oragc to generate Java classes from a schema:

Any thoughts?
Here's the part where it is getting the error:

I would recommend using JAXB instead of the Oracle class generator. This will give a standards based object-to-XML platform.
Oracle provides two JAXB implementations: one in the TopLink product, and the other in the XDK.
For an example of using TopLink JAXB see:
http://www.oracle.com/technology/products/ias/toplink/technical/tips/jaxb/index.htm
TopLink also provides the ability to map existing Java objects to an existing XML Schema, for an example of this see:

Map xsd complex type to existing java class without adding JAXB annotations

Hello
I've got a case where I should map an xsd complex type to an existing Java class without modifying that class, i.e. without adding JAXB annotations to that class.
Is this possible somehow?
As far as I've understood, the <javaType> declaration (adapter, parse/print methods) can only be used for xsd simple types.
Thanks, Tom

It should be possible to implement an XmlAdapter<...,...> which performs the required conversion between the original type and a JAXB-annotated type. Then, at the places where the original type is used, the @XmlJavaTypeAdapter annotation would be used.
The xjc compiler supports this for xsd simple types (xjc:javaType annotation), but not for complex types.
Any idea why this is restricted to simple types?
Would it be possible to implement a xjc plugin which does this for complex types?
Thanks Tom.

How to produce Java class from xsd programmatically?

As titled, I want to generage Java class/interface from xml schema via a program. There is a tool "xjc" that can do this manually.
I saw a sample that generates xsd file from Java class programmatically, I am figuring out if there is such a API to do the similar thing vice versa.
Thank you in advance!

You may want to check out this Java EE 5 Tutorial: http://docs.oracle.com/javaee/5/tutorial/doc/bnbah.html
It has an example of generating JAXB Java classes from an XML schema.
Can you provide a sample xsd schema and the resulting Java class/classes you want to have produced?
XMLBeans can use an xsd and generate Java classes for containing/manipulating XML objects, though I don't think that is what you are wanting.
You can also write an XSLT stylesheet that generates Java classes based on parameters that you provide to the stylesheet but there is no xsd schema involved. We used this at a major national bank to produce Java classes for batch processing of files sent/received between the bank and third pary companies. The Java classes generated were used to read/write delimited files, xml files and fixed format files to/from Java bean classes with the necessary getters/setters for manipulating the data.
Without a sample of what you are trying to doi it is hard to offer much help.

Errors generating Java classes from XML schema

How to omit xmlns from generated Java classes

Hi,
I'm using JAXB and xjc to generate Java classes from xsd fils. I've noticed that when marshalling these Java classes to XML string, there are few xmlns attributes that (as far as I concern :-))
"waste" space on the generated xml (space is critical resource in our application). Is there a way to order the Marashaller to omit these xmlns attributes from the generated files?
I tried to edit the generated xml string. I removed the xmlns attributes, but unmarshall it back to Java objects failed...
Thanks for any help,
Barak.

If the xmlns is specified in the xsd, it is also required in the xml. If you do not want it, however you can remove it from your xsd and then generate your xml

Add java classes as Additional Classes to web service and JAXB 2.0 usage

Hi,
I start using JDeveloper 11g TP3 to create web service. I encounter two problems.
1. I created a schema file as the following,
<schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="http://FromWSDL/" xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:tns="http://FromWSDL/">
<xsd:complexType name="sayHello">
<xsd:sequence>
<xsd:element name="arg0" type="xsd:string" default="Tommy"/>
<xsd:element name="arg1" type="tns:arg1Enum"/>
</xsd:sequence>
</xsd:complexType>
<xsd:simpleType name="arg1Enum">
     <xsd:restriction base="xsd:string">
     <xsd:enumeration value="preserve"/>
     <xsd:enumeration value="replace"/>
     <xsd:enumeration value="collapse"/>
     </xsd:restriction>
</xsd:simpleType>
<xsd:element name="sayHello" type="tns:sayHello"/>
<xsd:complexType name="sayHelloResponse">
<xsd:sequence>
<xsd:element name="return" type="xsd:string"/>
</xsd:sequence>
</xsd:complexType>
<xsd:element name="sayHelloResponse" type="tns:sayHelloResponse"/>
</schema>
then I used TopLink/JPA-->JAXB 2.0 Content Model from Schema, I got four java files: Arg1Enum.java, ObjectFactory.java, SayHello.java, and SayHelloResponse.java.
After, I create a java class with @WebService and @WebMethod annotation. Right Click on the web service class,
select Web Service Properties-->Additional Classes, I added the four java classes. but there are error message for SayHello and Arg1Enum
"the type SayHello cannot be serialized into XML and no custom serilizer has been defined for it"
2. In JDeveloper, I create Java model from the above schema, then reverse the steps, create a new schema from Java Model, the original schema and the schema from Java Model are not same, especially for "defaultValue" and "required" fields for the custom element(SayHello and Arg1Enum).
Any help will be appreciated

First what you mean by "deploying classes as web services"? Chances are you
can do it with something like Glue from The Mind Electric ... but chances
are that you don't want to. What are you trying to accomplish?

The WebLogic installation has one measly web services example, and it's an

Generate Java class from Oracle Type defined in Package w/ JPublisher

I was wondering if its possible to generate a Java class for an Oracle Type defined in a Package? I know passing the package name to JPublisher (SQL <package_name>) causes all Oracle Types in the Package to have a Java class generated for them but I'd like to be able to do this for an individual Type defined in a Package (something like SQL <package_name>.<type_name>).
Thanks for any information you can give me.

Hi Marinel,
The support for XSD import is limited on 10.1.2. If you can, you should consider moving to the 10.1.3 preview as the support for document style web services has improved. The other option will be to inline the schema in your WSDL.

XJC Tool - For building Java classes from Schema

Hi all,
I am using XJC tool for Building java classes from Schema.
Can we have any other tool for generating java classes from Schema?
Thanks in advance,
typurohit

Solved my own problem and forgot to post the answer: the "xsd:import" is also considered as a targetNamespace, so each xsd:import needs a package specified as well when using oracg. It would be helpful if the Oracle documentation had stated that, but it does not point this out.
