> axis-c engine: nillable problem: when minOccurs="0" and nillable="false", the
> serailization does NOT follow W3C schema standard
> -------------------------------------------------------------------------------------------------------------------------------
>
> Key: AXISCPP-970
> URL: https://issues.apache.org/jira/browse/AXISCPP-970
> Project: Axis-C++
> Issue Type: Bug
> Components: Serialization, Server - Apache module, Server - Engine,
> SOAP, XSD Types
> Affects Versions: 1.6 Beta
> Environment: Platform:
> Linux fedora 3.0
> Axis version:
> Server-side Axis C++ 1.6Beta
> XML Parser Lib:
> xersesc 2.6
> WSDL2ws tool by using axis java 1.3
> Client-side version Axis java 1.3
> Http Server Version:
> Apache 2.0.53
> Tomcat 2.0.58
> Reporter: Michael Xiong
> Priority: Critical
>
> [Introduction]:
> Maybe you have known that, the axis-c-1.5final's "nillable" dealing is
> completely wrong.
> I found that axis-c-1.6beta has taken some improvement on this area, it's
> good.
> But after really verify axis-c-1.6beta, I found axis-c-1.6beta seems has NOT
> resolved the old nillable issue correctly.
> At first, the design of "nillable" is too strange and hard-for-maintain in
> axis-c-1.6beta.
> The W3C's standard set default of "nillable" to "false", but axis-c-1.6beta
> set it's default to "true" in related constructor.
> Anyway, if axis-c-1.6beta can deal with "nillable" carefully & correctly in
> inner logic, there will has no problem.
> But after verify, I found that axis-c-1.6beta seems does not deal with
> "nillable" correctly in case of minOccurs="0".
> This problem occurred in nearly all XSD types.
> The below is a sample which has been verified by me, which indicate that
> axis-c-1.6beta has problem to deal with "nillable" in case of minOccurs="0".
> [Error Statement]:
> The below is a piece of WSDL which used by me:
> ... ...
> <xs:element name="TestingResponse">
> <xs:complexType>
> <xs:sequence>
> <xs:element minOccurs="0" maxOccurs="unbounded" name="testcase"
> type="xs:string"/>
> </xs:sequence>
> </xs:complexType>
> </xs:element>
> ... ...
> When I create server code by axis-c-1.6beta on this WSDL, build it and run,
> the response looks like this:
> <TestingResponse xmlns="... ...">;
> <testcase xsi:nil="true"></testcase>
> <testcase xsi:nil="true"></testcase>
> <testcase xsi:nil="true"></testcase>
> </TestingResponse>
> I wrote the related code logic(demo purpose only) in server module is like
> the below:
> xsd__string_Array * MyTesting::Testing(xsd__string Value0,xsd__string
> Value1,xsd__string Value2)
> {
> //<mxiong debug 2006/5/19
> xsd__string_Array* pIDs = new xsd__string_Array();
> xsd__string* p = new xsd__string[3];
> p[0] = strdup("");
> p[1] = strdup("");
> p[2] = strdup("");
> pIDs->set(p,3);
> return pIDs;
> //>mxiong debug 2006/5/19
> }
> You can found that the response xsi:nil="true" is wrong.
> That will cause my client application rejecting to accept this response for
> it does not follow contracted schema.
> [My Solution]:
> After analyzing and debug to axis-c-1.6beta code, I modified
> soap/xsd/String.cpp, it became OK.
> My modification is like the below:
> String::String(const xsd__string value)
> {
> #ifdef ENABLE_AXISTRACE
> if (axiscpp::AxisTrace::isTraceOn())
> axiscpp::AxisTrace::traceEntry("String", "String",
> this, 1,
> TRACETYPE_STRING, 0, ((void*)&value));
> /* AUTOINSERTED TRACE */
> #endif
> //<mxiong debug 2006/5/19
> // if (value)
> // {
> setNil(false);
> serialize(value);
> // }
> //>mxiong debug 2006/5/19
> {
> #ifdef ENABLE_AXISTRACE
> if (axiscpp::AxisTrace::isTraceOn())
> axiscpp::AxisTrace::traceExit("String",
> "String", this, 0); /* AUTOINSERTED TRACE */
> #endif
> return;
> }
> }
> AxisChar* String::serialize(const xsd__string value) throw (AxisSoapException)
> {
> #ifdef ENABLE_AXISTRACE
> if (axiscpp::AxisTrace::isTraceOn())
> axiscpp::AxisTrace::traceEntry("String", "serialize",
> this, 1,
> TRACETYPE_STRING, 0, ((void*)&value));
> /* AUTOINSERTED TRACE */
> #endif
> MinLength* minLength= getMinLength();
> //<mxiong debug 2006/5/19
> unsigned int nLen = 0;
> //>mxiong debug 2006/5/19
> if (minLength->isSet())
> {
> //<mxiong debug 2006/5/19
> if (NULL != value)
> {
> nLen = strlen(value);
> }
> if (nLen < (unsigned int) minLength->getMinLength())
> //>mxiong debug 2006/5/19
> // if (strlen(value) < (unsigned int) minLength->getMinLength())
> {
> AxisString exceptionMessage =
> "Length of value to be serialized is shorter than MinLength
> specified for this type. Minlength = ";
> AxisChar* length = new AxisChar[10];
> sprintf(length, "%d", minLength->getMinLength());
> exceptionMessage += length;
> exceptionMessage += ", Length of value = ";
> sprintf(length, "%d", strlen(value));
> exceptionMessage += length;
> exceptionMessage += ".";
> delete [] length;
>
> throw AxisSoapException(CLIENT_SOAP_SOAP_CONTENT_ERROR,
> const_cast<AxisChar*>(exceptionMessage.c_str()));
> }
> }
> delete minLength;
>
> MaxLength* maxLength = getMaxLength();
> if (maxLength->isSet())

> } else
> {
> valueAsString = "";
> }
> //>mxiong debug 2006/5/19
> // AxisString valueAsString = value;
> AxisChar* serializedValue = (AxisChar*)

> So I think axis-c-1.6beta has bug in dealing with "nillable" for nearly any
> XSD types, especially for String type as my sample indicated.
> [Suggestion]
> Would you like to give it a careful check to correct this problem in
> axis-c-1.6beta?
> My modification may be regarded as a candicate solution for you to resolve
> this problem, but I wish maybe a better detail design for axis-c-1.6beta on
> "nillable" area may be better.
