I am running into some problems returning multiple arrays and multiple
multidimentional arrays. I am using SOAP 2.2 and Xerces 1.4.2.
The provider (totally moched up so don't laugh at me) code fragment
below compiles, runs and appears to responde ok:
>>>>
java.util.Vector params = new java.util.Vector();
params.add(new Parameter("Customers_Customer_CustomerID",
String[].class, new String[] {"1", "2"}, Constants.NS_URI_SOAP_ENC));
params.add(new Parameter("Customers_Customer_ContactTitle",
String[].class, new String[] {"CEO", "President"},
Constants.NS_URI_SOAP_ENC));
params.add(new Parameter("Customers_Customer_Country",String[].class,
new String[] {"US", "DE"}, Constants.NS_URI_SOAP_ENC));
params.add(new Parameter("Customers_Customer_Addresses_Address_Label",
String[][].class, new String[][] {new String[] {"home", "office"}, new
String[] {"home", "batcave"}}, Constants.NS_URI_SOAP_ENC));
params.add(new Parameter("Customers_Customer_Addresses_Address_Street",
String[][].class, new String[][] {new String[] {"12345 Fake St.", "54321
Saint Fake Ln."}, new String[] {"10100 Binary Rd.", "1 Dark Road"}},
Constants.NS_URI_SOAP_ENC));
params.add(new Parameter("Customers_Customer_Addresses_Address_City",
String[][].class, new String[][] {new String[] {"Springfield",
"Shelbyville"}, new String[] {"Komputar", "Ubertown"}},
Constants.NS_URI_SOAP_ENC));
params.add(new Parameter("Customers_Customer_Addresses_Address_State",
String[][].class, new String[][] {new String[] {"IL", "IL"}, new
String[] {"MU", "MU"}}, Constants.NS_URI_SOAP_ENC));
params.add(new Parameter("Customers_Customer_Addresses_Address_Zip",
String[][].class, new String[][] {new String[] {"86213", "86321"}, new
String[] {"HFD234", "HFD567"}}, Constants.NS_URI_SOAP_ENC));
params.add(new Parameter("Customers_Customer_Age", String[].class, new
String[] {"45", "35"}, Constants.NS_URI_SOAP_ENC));
try
{
Response resp = new Response(m_TargetObjectURI, // URI
m_MethodName, // Method
new Parameter("Result", Boolean.class, new Boolean(true),
Constants.NS_URI_SOAP_ENC), // ReturnValue
params, // Params
null, // Header
Constants.NS_URI_SOAP_ENC, // encoding
responseContext); // response soapcontext - not supported yet
Envelope env = resp.buildEnvelope();
StringWriter sw = new StringWriter();
env.marshall(sw, m_Call.getSOAPMappingRegistry(), responseContext);
responseContext.setRootPart(sw.toString(),
Constants.HEADERVAL_CONTENT_TYPE_UTF8);
}
catch (Exception e)
<<<<
With the test client code below:
>>>>
Call call = new Call();
call.setTargetObjectURI("urn:eightball-simple-request");
call.setMethodName("fortune");
Response resp = call.invoke(
new java.net.URL("http://localhost:8080/soap/servlet/rpcrouter";),
"urn:eightball-simple-request");
if (resp.generatedFault())
{
Fault fault = resp.getFault();
System.out.println(fault.toString());
fail(fault.toString());
}
else
{
Parameter ret = resp.getReturnValue();
System.out.println(ret.getValue().toString());
}
I get the following evelopes:

The exception is at this line:

Does anyone have any clues as to what is causing this? Please
understand that the array thing is not my idea. It comes as a
requirement from someone who makes a lot more money than I do and has no
clue about SOAP and XML. I would much rather be returning the actual
XML DOM but we have a requirement not to. Don't ask me why, I really
don't know...
