Subject svn commit: r544626 - in /webservices/axis2/trunk/java/modules/jaxbri: project.properties src/org/apache/axis2/jaxbri/JaxbSchemaGenerator.java
Date Tue, 05 Jun 2007 20:47:46 GMT
Author: dims
Date: Tue Jun  5 13:47:45 2007
New Revision: 544626

URL: http://svn.apache.org/viewvc?view=rev&rev=544626
Log:
initial checkin for a skeleton jaxb schema generator. the idea is to collect the list of all
the classes corresponding to the parameters and return types etc for all the methods, generate
their schema using jaxbri schemagen and then call DefaultSchemaGenerator's generateSchemas
to add whatever else is needed for the element wrappers for each method etc.
