Description

We updated the axis2 version from 1.5.1 to 1.6.2.
There are more than 200 stubs created in axis2-1.5.1 version. Our goal is to use axis2.1.6.2 version with old(1.5.1) generated stub.

The old stub uses MTOMAwareXMLStreamWriter class everywhere, but this class is removed in axis2 1.6.2 version.

Am getting below error when I try to use axis2 1.6.2 version with old stubs to make service call.

The reason is
public abstract void serialize(QName paramQName, OMFactory paramOMFactory, MTOMAwareXMLStreamWriter paramMTOMAwareXMLStreamWriter)
throws XMLStreamException, ADBException;
above method is not there in ADBBean and MTOMAwareXMLStreamWriter class is removed in 1.6.2.

So is there any way we can use old generated stubs with latest axis2 ? If so please guide us how.
If we can not use, is there any patch we can apply to make this work ? We don't want to regenerate stubs using latest axis2 due to business requirements.

Thanks in Advance,
