Dynamically generating java classes from XSD file using XmlBeans
Hi,
I am fairly new to XMLBEans. I know one can generate java classes from xsd
(XML SChema) file using scomp. But I was wondering if there is any way it
would be done on the fly. For Example, the user would be able to specify
the file path for the XSD file to the program, and the program would then
load the file, compile it, generate the java classes and manipulate the
classes as required.
Could this be done?
Any help would be greatly appreciated.
Best Regards
Arif

Posted by Radu Preotiuc-Pietro <ra...@bea.com>.
Also XmlBeans.compileXmlBeans() is a good place to look at because,
unlike the script, is part of the "public" API which means
backards-compatbility and better documentation.

RE: Dynamically generating java classes from XSD file using XmlBeans
Posted by Wing Yew Poon <wp...@bea.com>.
Arif,
Nathan is right.
If you look at the scomp script, it basically calls java on
org.apache.xmlbeans.impl.tool.SchemaCompiler with your arguments.
Look at the xmlbeans source in the svn repository.
SchemaCompiler.java is under the src/xmlcomp/ hierarchy.
SchemaCompiler has a static nested class SchemaCompiler.Parameters.
What you need to do is to create a SchemaCompiler.Parameters instance,
set its fields appropriately, and then call compile() with your
parameters.
Good luck.

Hi
Imagine that the CLI tool you use is really just a shell script
calling java on a java class file which has a main that takes the
arguments of the file that you want to compile, and then reads and
compiles it.
So, what you want to do is find the java class that is invoked by the
script, and replicate what its main() does.
You can also invoke the java compiler as a call to it's main, and
then use reflection to invoke your new class.
The rest is an exercise for the reader :-)
