Serializers/Deserializers
I've been trying to develop my own serializer & deserializer for some
java classes such as the
java.net.URL class in order to pass URL's to a service method, but the
server sends back a fault:
Fault Code = SOAP-ENV:Server.Exception:
Fault String = org/apache/soap/util/xml/Deserializer
I've attempted to write serializers/deserializers for a simple class
also (class contains only Strings) instead of using the BeanSerializer
and I
still get the above exception.
This is a critical issue...
Below is the code:
Deployment Descriptor
--------------------------------------------------------------------------------------------------------------
<isd:service xmlns:isd="http://xml.apache.org/xml-soap/deployment"
id="urn:SimpleURLService">
<isd:provider type="java"
scope="Session"
methods="serviceMethod">
<isd:java
class="examples.omnitide.SimpleURLService.SimpleURLService"
static="false"/>
</isd:provider>
<isd:faultListener>org.apache.soap.server.DOMFaultListener</isd:faultListener>
<isd:mappings>
<isd:map encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:xsd="http://www.w3.org/1999/XMLSchema"
qname="xsd:URL"
javaType="java.net.URL"
xml2JavaClassName="examples.omnitide.SimpleURLService.URLDeserializer"/>
</isd:mappings>
</isd:service>
Client that calls soap service
--------------------------------------------------------------------------------------------------------------
// Map the types
SOAPMappingRegistry smr = new SOAPMappingRegistry();
URLSerializer ser = new URLSerializer();
URLDeserializer des = new URLDeserializer();
smr.mapTypes(Constants.NS_URI_SOAP_ENC, new
QName("urn:SimpleURLService", "URL"),
URL.class, ser, des);
// Build the call
Call call = new Call();
call.setSOAPMappingRegistry(smr);
call.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);
call.setTargetObjectURI("urn:SimpleURLService");
call.setMethodName("serviceMethod");
Vector params = new Vector();
params.addElement(new Parameter("request", URL.class, url,
null));
call.setParams(params);
Serializer
--------------------------------------------------------------------------------------------------------------
import java.net.URL;
public class URLSerializer implements Serializer
{
public void marshall(String inScopeEncStyle, Class javaType, Object
src,
Object context, Writer sink, NSStack nsStack,
XMLJavaMappingRegistry xjmr, SOAPContext ctx)
throws IllegalArgumentException, IOException
{
nsStack.pushScope();
SoapEncUtils.generateStructureHeader(inScopeEncStyle, javaType,
context,
sink, nsStack, xjmr);
sink.write(StringUtils.lineSeparator);
URL src2 = (URL) src;
Parameter param;
param = new Parameter("URL", String.class, src2.toString(), null);
xjmr.marshall(inScopeEncStyle, Parameter.class, param, null,
sink, nsStack, ctx);
sink.write(StringUtils.lineSeparator);
sink.write("</" + context + ">");
nsStack.popScope();
}
}
Deserializer
--------------------------------------------------------------------------------------------------------------
public class URLDeserializer implements Deserializer
{
public Bean unmarshall(String inScopeEncStyle, QName elementType, Node
src,
XMLJavaMappingRegistry xjmr, SOAPContext ctx)
throws IllegalArgumentException
{
Element root = (Element)src;
Element tempEl = DOMUtils.getFirstChildElement(root);
URL url = null;
while (tempEl != null)
{
Bean paramBean = xjmr.unmarshall(inScopeEncStyle,
RPCConstants.Q_ELEM_PARAMETER,
tempEl, ctx);
Parameter param = (Parameter)paramBean.value;
String tagName = tempEl.getTagName();
if (tagName.equals("URL"))
{
try
{
url = new URL( (String)param.getValue() );
}
catch (Exception e)
{
throw new IllegalArgumentException("Problem
instantianting bean: " + e.getMessage());
}
}
tempEl = DOMUtils.getNextSiblingElement(tempEl);
}
return new Bean(URL.class, url);
}
}

There is class loader info at
http://jakarta.apache.org/tomcat/tomcat-4.0-doc/class-loader-howto.html
although some of the info there for 4.0 already seems to be out of date for
4.0.1.

Good to hear you conquered the problem. I just downloaded 4.0.1 the other
day and was interested to see the things that changed, such as the libs
already in the path ready for servlets to use, and the "standards" for where
to put shared code. It's nice to not toy with the startup scripts at all.

Re: Serializers/Deserializers
Posted by David Turner <tu...@genome.wi.mit.edu>.
Hi Scott,
Thanks for getting back to me.
I did manage to figure out why it wasn't working -- I changed tomcats classpath
to point to my stuff and it didn't like this. I jar'ed things up and placed it
in WEB/INF/lib of soap and it worked fine. Going the classpath route, the
service class was found but any supporting classes were having the problem of
not be found.
I'll have to read up on tomcats classloader.
Thanks again.

Re: Serializers/Deserializers
Posted by David Turner <tu...@genome.wi.mit.edu>.
Hi Scott,
Thanks for getting back to me.
I did manage to figure out why it wasn't working -- I changed tomcats classpath
to point to my stuff and it didn't like this. I jar'ed things up and placed it
in WEB/INF/lib of soap and it worked fine. Going the classpath route, the
service class was found but any supporting classes were having the problem of
not be found.
I'll have to read up on tomcats classloader.
Thanks again.

This is a *guess*, but I still have not got a full grip on the different
class loading schemes used within the container.

Re: Serializers/Deserializers
Posted by Scott Nichol <sn...@computer.org>.
There is class loader info at
http://jakarta.apache.org/tomcat/tomcat-4.0-doc/class-loader-howto.html
although some of the info there for 4.0 already seems to be out of date for
4.0.1.
