embedding a string into structure XML RPC request
Hi guys!
I recently used apache xml-rpc library to create a client that send XML data
to the server to get individual details.
Now the server is created by a third party entity and they have provided us
the guidelines to create clients accordingly.
The XML data that is needed to be sent to the server is as follows:
/////////////////////////////////////////////////////////////////////////////////////////////////////////////////
<?xmlversion="1.0"?>
<methodCall><methodName>GetAccountDetailsRequest</methodName>
<params>
<value>
<struct>
<member><name>originNodeType</name><value><string>TEST</string></value></member>
<member><name>originHostName</name><value><string>TEST</string></value></member>
<member><name>originTransactionID</name><value><int>12345</int></value></member>
<member><name>originTimeStamp</name><value><dateTime.iso8601>20080229T13:37:00+0000</dateTime.iso8601></value></member>
<member><name>subscriberNumber</name><value><string>826953722</string></value></member>
</struct>
</value>
</params>
</methodCall>
/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
Now i am unable create exact structure for this kind of XML data. The code
is below:
//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
import java.net.*;
import java.util.*;
import org.apache.xmlrpc.XmlRpcException;
import org.apache.xmlrpc.client.*;
public class XMLClient {
public XMLClient() {
}
public static void main(String[] args) {
HashMap data = new HashMap();
data.put("originNodeType", new String("TEST") );
data.put("originHostName", new String("TEST") );
data.put("originTransactionID", new Integer(12345));
data.put("originTimeStamp", new Date());
data.put("subscriberNumber", new String("826629828") );
Vector params = new Vector();
Object paramsR = new Object();
params.addElement(data);
XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl();
try
{
config.setServerURL(new
URL("http://accountdetailsserver:8080/RPC2"));
XmlRpcClient client = new XmlRpcClient();
client.setConfig(config);
client.execute("BalanceEnquiryTRequest", params);
paramsR = (Object)client.execute("GetAccountDetailsRequest",
params);
} catch (MalformedURLException e)
{
System.err.println(e);
} catch (XmlRpcException e)
{
System.err.println(e);
}
System.out.println( paramsR );
}
}
//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
The output of this code is as below
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
<?xmlversion="1.0"?>
<methodCall><methodName>GetAccountDetailsRequest</methodName>
<params>
<value>
<struct>
<member><name>originNodeType</name><value>TEST</value></member>
<member><name>originHostName</name><value>TEST</string></member>
<member><name>originTransactionID</name><value><int>12345</int></value></member>
<member><name>originTimeStamp</name><value><dateTime.iso8601>20080229T13:37:00+0000</dateTime.iso8601></value></member>
<member><name>subscriberNumber</name><value>826953722</value></member>
</struct>
</value>
</params>
</methodCall>
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
The tag <string></string> is missing from the output xml data above.
<member><name>originNodeType</name><value><string>TEST</string></value></member>
<member><name>originHostName</name><value><string>TEST</string></value></member>
<member><name>subscriberNumber</name><value><string>826953722</string></value></member>
and therefore the query responds with an error code from the server end.
Please help me solve this issue, i ve tried to search for the solution a lot
but all in vain.
Regards,
Fahad

HI Fahad,
could you show us your string TAG problem solution?

You don't need to create a custom parser. The serializer is sufficient
in your case. Btw, it would be nice if you could create an entry on
http://wiki.apache.org/ws/XML-RPC, which describes what you did,
because your problem is somewhat of an FAQ.
Thanks,
Jochen

Hi Jochen,
I have solved that string TAG problem and now all my structures containing
the the string values are represented by <string> TAG. I also have modified
my client to use a different Date format.
The method you have posted on the below link under the custom data types:
http://ws.apache.org/xmlrpc/advanced.html
/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
public TypeParser getParser(XmlRpcStreamConfig pConfig, NamespaceContextImpl
pContext, String pURI, String pLocalName) {
if (DateSerializer.DATE_TAG.equals(pLocalName)) {
return new DateParser(pFormat);
} else {
return super.getParser(pConfig, pContext, pURI, pLocalName);
}
}
////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
I am unable to understand what this method is used for. And the variable
'pFormat' what exactly is this.
I understand that
private DateFormat newFormat();
created the custom format and
public TypeSerializer getSerializer();
is the serializer for the newFormat()
Is there any documentation available that describes the fucntionality of
these classes.
regards,
Fahad

Thanks Jochen, now i atleast know that its not the code that i wrote was
faulty;
I am now gonna start looking into "custom data type" its a big task for me
since i am not really gud at understanding by looking at the javadocs;

The XML-RPC spec specifies the absence of any type indicator as
equivalent with the use of the "string" indicator. In other words, it
is the servers fault that it doesn't accept your response.
However, to know that won't help you. Visit
http://ws.apache.org/xmlrpc/advanced.html and find the section on
"Custom data types". What you need is to have a custom type factory
with a custom TypeSerializer for the String class. The default
TypeSerializer for string is omitting the <string> tag, your's would
add it.
