[AXIS-2421] incorrect Bean deserialisation - deserialised object's constructor invoked with incorrect argument values - axis seems to confuse types

• Type: Bug
• Status: Open
• Priority: Minor
• Resolution: Unresolved
• Affects Version/s: 1.3
• Component/s: Serialization/Deserialization
• Environment: Client on Windows XP Pro, Server (Tomcat and Axis) on RedHat Linux
• Assignee: Unassigned

Description

Problem:

• transmitting a simple object via SOAP
• object has 4 attributes, two "long" values, one "int" value and one Java String value
• problem is with deserialisation of longs
• object's constructor is invoked with the first long's value for both long parameters
• 2nd long's value is never used

• problem seems to be in org.apache.axis.encoding.ConstructorTarget.java line 88
• args[c] = values.get causes the first value of a type to be returned, regardless of whether or not ir was returned already

• fix implemented by replacing above line with:
  args[c] = values.remove;

• not sure of the wider implications of this fix, however.

/*

• Some client code to test this
  */
