Generate Java classes from .XSD files...?
Solution 1:
JAXB does EXACTLY what you want. It's built into the JRE/JDK starting at 1.6
Solution 2:
To expand on the "use JAXB" comments above,
In Windows
"%java_home%\bin\xjc" -p [your namespace] [xsd_file].xsd
e.g.,
"%java_home%\bin\xjc" -p com.mycompany.quickbooks.obj quickbooks.xsd
Wait a bit, and if you had a well-formed XSD file, you will get some well-formed Java classes
