I do not know how Axis handles this. If the service produces WSDL, that would be the obvious approach for Axis, but without WSDL, I do not know: try [EMAIL PROTECTED]

Thanks a lot, Donald PS.

Subsequent to the 2.3.1 release, I wrote a PropertyBagSerializer (http://cvs.apache.org/viewcvs.cgi/*checkout*/ws-soap/java/src/org/apach e/soap/encoding/soapenc/PropertyBagSerializer.java?rev=1.3) that can be used for this. You would need to either get the last nightly build and use it instead of 2.3.1, or just grab the code from the CVS link above, compile it, and put the byte code in your classpath. Your client code would look like SOAPMappingRegistry smrr = new SOAPMappingRegistry (); PropertyBagSerializer pbs = new PropertyBagSerializer (); smrr.mapTypes(Constants.NS_URI_SOAP_ENC, new QName("http://xml.apache.org/xml-soap";, "SOAPStruct"), Hashtable.class, null, pbs); Scott Nichol Do not send e-mail directly to this e-mail address, because it is filtered to accept only mail from specific mail lists. ----- Original Message ----- From: "Chen, Donald" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, August 06, 2004 5:08 PM Subject: How to deseralize a hashtable? Hi, All. I have a WS in Perl via SOAP::Lite. Via this WS, a client can call a method getAllInfo() which returns a Hashtable. I wrote a WS client in perl with success, but writing a WS client in Java via the Apache-Soap-2.3.1 is never successful. Specifically, the error I got is like this: Exception in thread "main" java.lang.IllegalArgumentException: No Deserializer found to deserialize a 'http://xml.apache.org/xml-soap:SOAPStruct' using encoding style 'http://schemas.xmlsoap.org/soap/encoding/'. at org.apache.soap.util.xml.XMLJavaMappingRegistry.queryDeserializer(XMLJav aMappingRegistry.java:206) at org.apache.soap.util.xml.XMLJavaMappingRegistry.unmarshall(XMLJavaMappin gRegistry.java:302) at org.apache.soap.encoding.soapenc.ParameterSerializer.unmarshall(Paramete rSerializer.java:206) at org.apache.soap.util.xml.XMLJavaMappingRegistry.unmarshall(XMLJavaMappin gRegistry.java:314) at org.apache.soap.rpc.RPCMessage.unmarshall(RPCMessage.java:417) at org.apache.soap.rpc.RPCMessage.extractFromEnvelope(RPCMessage.java:197) at org.apache.soap.rpc.Response.extractFromEnvelope(Response.java:142) at GetChemDef.main(GetChemDef.java:167) Here is the payload I got from the server: <?xml version="1.0" encoding="UTF-8"?><SOAP-ENV:Envelope xmlns:namesp2="http://xml.apache.org/xml-soap"; SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"; xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"; xmlns:xsd="http://www.w3.org/2001/XMLSchema";><SOAP-ENV:Body><namesp17:ge tAllInfoResponse xmlns:namesp17="http://johnny5:8002/ChemDefServices";><s-gensym68 xsi:type="namesp2:SOAPStruct"><delimilator xsi:type="xsd:string">|</delimilator><chemistry xsi:type="xsd:string">caffeine</chemistry><a xsi:type="xsd:string">aPiece</a><smiles xsi:type="xsd:string">c1ccccc1</smiles><b xsi:type="xsd:string">bPiece</b><syntaxOk xsi:type="xsd:int">1</syntaxOk></s-gensym68></namesp17:getAllInfoRespons e></SOAP-ENV:Body></SOAP-ENV:Envelope> This payload refects a hashtable: %h = ( chemistry => 'caffeine', a => 'aPiece', b => 'bPiece', smiles => 'c1ccccc1' ); Here are the major code lines (as you can see, I was trying to use the HashtableSerializer ): // build the call.

Do I need to write my own deseralizer for the hashtable? If yes, how to incorporate the deseralizer to the main funciton? Thanks in advance, Donald
