We have a functioning SOAP client/server system written in Borland Delphi
which isn't scaling very well at all; it works fine until we get to about
45-50 clients at a time. I'm a newbie with SOAP but I have been tasked with
porting the server side to a Tomcat/Axis system, while keeping it compatible
with the Delphi client. I've been working on this for a week, and can't
seem to get a deserializer to work for the requests as the client sends
them. If somebody could help me set up a skeleton java class for the server
side (or point me to a reverse-engineering tool which would do it), I would
be extremely grateful. I don't need help with coding the individual methods
on the server; I can handle that part. I just can't figure out how to get
the stubs and class(es) set up properly to allow data to flow back and
forth.
In the below messages, you can see that some of the data is sent as
attributes, and some as elements. The Delphi programmers did it that way to
save a few bytes of bandwidth, and it is probably the biggest problem I'm
having, to retrieve the data from the attributes.
The client's request looks like:
<?xml version="1.0"?>
<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/";>
<SOAP-ENV:Body
SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";
xmlns:NS2="urn:EDDRI">
<NS1:DataLine xmlns:NS1="urn:EDDIf-IEDDSrvIf">
<FD href="#1"/>
</NS1:DataLine>
<NS2:TES_Req id="1" xsi:type="NS2:TES_Req" XID="43">
<Site xsi:type="xsd:string">
90555//270
</Site>
<Time xsi:type="xsd:string">
2004-06-23 00:01:37
</Time>
<Data xsi:type="xsd:string">
E,0,10,040623,000137
</Data>
</NS2:TES_Req>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
And the corresponding response from the server is:
<?xml version="1.0"?>
<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/";>
<SOAP-ENV:Body
SOAP-ENC:encodingStyle="http://schemas.xmlsoap.org/soap/envelope/";>
<NS1:DataLineResponse
xmlns:NS1="urn:EDDIf-IEDDSrvIf"
xmlns:NS2="urn:EDDRI">
<NS2:TES_Rsp id="1"
xsi:type="NS2:TES_Rsp" XID="43">
<Status xsi:type="xsd:int">0</Status>
</NS2:TES_Rsp>
<return href="#1"/>
</NS1:DataLineResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
Thanks for any help!!
