Hi, Unfortunately in current Axis release (Axis 1.2 RC2) this problem can not be resolved in any configuraton way, so I just had to patch two Axis source files: SerializationContext and RPCParam.
org.apache.axis.encoding.SerializationContext old way: 134: /** 135: * Send an element with an xsi:nil="true" attribute for null 136: * variables (if Boolean.TRUE), or nothing (if Boolean.FALSE). 137: */ 138: private Boolean sendNull = Boolean.TRUE; new way: 134: /** 135: * Send an element with an xsi:nil="true" attribute for null 136: * variables (if Boolean.TRUE), or nothing (if Boolean.FALSE). 137: */ 138: private Boolean sendNull = Boolean.FALSE; org.apache.axis.message.RPCParam old way: 177: context.serialize(getQName(), // element qname 178: null, // no extra attrs 179: value, // value 180: xmlType, // java/xml type 181: Boolean.TRUE, wantXSIType); new way: 177: context.serialize(getQName(), // element qname 178: null, // no extra attrs 179: value, // value 180: xmlType, // java/xml type 181: Boolean.FALSE, wantXSIType); -- Regards, Andrey AK> Hi all, AK> I'm very new to this and probably the problem I've got is basic for AK> you (but still I didn't find any clues in archive).
