Re: [Axis2] ArrayIndexOutOfBounds driving me crazy
Hi, ADB is the Axis2 databinding framework with simple schema support. ADB (even though the default) is not meant to support all the schema constructs but acts as a 80% case for the databinding needs. XMLBeans on the other hand is a full blown XML to Object mapping (http://xmlbeans.apache.org/) and supports almost all the schema constructs (from my experience it did not fail to any of the schemas yet!). Axis2 supports the use of XMLBeans databinding framework .You can switch the databinding implementation by using the -d switch, use -d xmlbeans to generate XMLBeans stubs. BTW for XMLBeans you would be better off in reading some documentation before you drill down into the details. Ajith On 2/26/06, Bram Biesbrouck [EMAIL PROTECTED] wrote: Hi, Yes, I'm using ADB.
