Re: Help wanted to diagnose an xsd error in running Java code generator

["Nacho G. Mac Dowell" <ig...@informa.es>]

Hi Shaoguang, the problem is that your xsd is not valid. If you want to 
go the quick way, either remove the targetNamespace or add to the 
xs:shema element xmlns="com.jaxme". But I recommend reading:

http://www.w3.org/TR/xmlschema-0/#NS

BTW, the ant task is going to complain because it won't be able to 
derive the package name from the targetNamespace. Either change your 
targetNamespace to a valid URL or specify a package on the ant task. 
 From what I see, you want your targetNamespace to be http://jaxme.com

best regards,

nacho
