Description

We make a product for running Oracle stored procedures and SQL statements that is designed to work with Axis. This involves creating data structures that contain byte[] arrays. One of our regression tests involves the following method:

public axis12bug.plsql.RawProcReturn servicePlsqlRawProc
(byte[] paramInParam
,byte[] paramInOutParam) throws DAOFactoryServiceException

RawProcReturn looks like this:

public class RawProcReturn
{
public byte[] paramOutParam = null;
public byte[] paramInOutParam = null;

}

This failing against Axis 1.2.1 but not Axis 1.1 because it throws the following error:

• Could not convert java.lang.Byte to bean field 'paramOutParam', type [B
• Exception:
  java.lang.IllegalArgumentException: argument type mismatch

This bug may be a clone of Axis-1985.

We have zipped a test case and uploaded it to:

http://www.orindasoft.com/public/friends/smallarraysbug.zip

We regard this as a blocker because:

1. This works in Axis 1.1.
2. The ability to work with objects that have byte[] arrays is fundamental to anyone working with BLOB or CLOB data.
