java.lang.IllegalArgumentException: argument type mismatch When deserializing byte[]

• Key: AXIS-1986
• Type: Bug
• Status: Resolved
• Resolution: Fixed
• Priority: Blocker
• Assignee: Unassigned
• Reporter: David Rolfe
• Component/s: Serialization/Deserialization
• Affects Version/s: 1.2RC3

Environment

   Web Servers: Tomcat 4.1.31, 5.0.28, 5.5.4
Axis Versions: Not present in Axis 1.1. Occurs in Axis 1.2 all releases up to 1.2.1.
Java: 1.4.2_04
Operating Systems: Present on Windows XP and Solaris 5.8

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.

uploading zip from URL.

We will happily re-run our regression tests on a version of Axis that is believed to fix this bug. We run a Suite of tests on various combinations of Axis 1.1/1.2.1 and Tomcat. See:

Have uploaded Axis1985WSDL.zip to Axis-1985. It contains WSDL and WSDD for this problem.

Same as AXIS-1985. Please codegen with latest nightly (you will see arrayMapping's in your deploy.wsdd).

thanks,
