Here is an example of generating an XML schema from Java classes:
http://wiki.eclipse.org/EclipseLink/Examples/MOXy/JAXB/GenerateSchema
After long try i am able to generate XSD based on POJO using JAXB schemagen.In my main class based on which i was trying to generate XSD was refereeing some other classes which was in other packages and i was not able to figure it out how to set class path for these classes but on removing those references was able to get schemagen working will explore now how to set class path for schemagen

I'm currently working on the a Flight API integration on my company platform and I'm facing some issues.
I need to use a data binding plugin in order to generate Java classes based on the provided XSD files. Nevertheless, I have tried many plugins such as ADB, CXF or JIBX and I got binding errors with all of them.
I have been able to fix these errors by modifying the XSDs in order to "eliminate" the errors but I think I'll get issues later due to these changes.
So my question is quite simple, has anybody of you been able to find a good plugin which is able to handle the XSDs ?
Thanks !
You need to use JAXB to generate java classes from XML schema ,please check this SO question .
If you want specific plugin for your IDE please check this for IntelliJ IDEA and Eclipse.
I have a XSD file ( which contains complex structure ). I generated java class using XJC command.
Now I want to know which is parent class and which is child class programmatically.
Any idea or help will be highly appreciated
Cheers
I suggest using the Java Reflection API, more specifically the Class.getSuperClass() method.
i would like to know how to parse xml file in java and convert results to javabean from it. Can anyone guide me thanks?
A really simple and convenient way: http://simple.sourceforge.net/
You can find many examples there for using it, too.
JAXB allows you to write an XSD to which your XML file should conform and then generate the java beans automatically. You don't need to hand-code the beans yourselves.
Check out the tutorial at http://docs.oracle.com/javase/tutorial/jaxb/intro/.
Is there a way in Java to create an XSD schema? I am trying to create a new schema .xsd file according to the number of attributes and their type given to me as input. Is there a package that can help me to do this job?
JAXB Schemagen can generate XSD Schema from Java Classes.
try jlibs library. you can see you to create how to create xml schema using jlibs.xml.xsd.XSDocument at the end of the wiki
Use the eclipse's xsd api has the ability to create, parse and update a xsd. Refer to their documentation for how-to details.
With Apache XmlSchema you can construct XML schemata in-memory and convert them to string.
In my project I've used the JAXB compiler to generate an object model "home made API" taking the XML schema as XJC input. You can find the file here: http://www.w3.org/2001/XMLSchema.xsd
Another solution is to use the Eclipse project MDT XSD (http://www.eclipse.org/modeling/mdt/?project=xsd#xsd) but I found it not well documented and easily integratable in a Maven build.
How can I get java classes from an xml file?
In this situation, I don't have an XML schema and this way I can't use JAXB, Castor or other xml binding API as far as I know.
You can generate schema from XML file using certain tools. Then, use Apache XMLBEANS to create your classes.
XStream is great for XML -> objects and vice versa. Fast, lightweight, and works well without any schema.
Altova is also the best to generate java Classes from XML/XSD
