I have difficulty in writing a schema in XSD1.1. XML structure is already defined and used by many teams, so changing the xml is not an option to me.
May be I can't explain everything I tried here. XSD has evolved so much since start. I just hope some ppl can understand the problem clearly.. Would be great if someone can share their way of solving this problems..
How XML looks like (in simplified format)
<Node>
<Create Type="A">
<Attr Name="Type1" Val="123"/>
<Attr Name="Type2" Val="Water"/>
<Attr Name="Type3" Val="2019-12-01T08:00:00"/>
</Create>
<Create Type="B">
<Attr Name="TypeM" Val="OB123"/>
<Attr Name="Type2" Val="Fire"/>
<Attr Name="TypeK" Val="2019-12-01T08:00:00"/>
<Attr Name="TypeN" Val="11.567"/>
</Create>
</Node>
Problem:
Based on "Type" attribute in Element<Create> - Number of <Attr> Elements changes (There are 80 types). Each Type can allow specific set of child attr. In above e.g, when Type = A, it can have only 3 children and specifically Type1, Type2 and Type3.
Based on value of "Name" attribute in Element <Attr> , attribute "Val" can have range of Values. In Xml shown above, Type2 can have {Fire, Water}
Based on value of "Name" attribute in Element<Attr> , define the type of second attribute "Val" which can be (date,integer, string, float etc)
The XSD I am trying to write looks something like this (actual XSD and XML are huge)..

<xs:complexType name="NodeType">
<xs:sequence>
<xs:element name="Create">

Thanks to this post - How to make type depend on attribute value using Conditional Type Assignment.
After spending days.. I am able to solve 3 problems (one at a time) stated above.. I am facing issue when I tried to club all 3 solutions in one nice compact xsd.
For Eg.. When I try to solve Problem 3, solution to problem 1 is messed up.
<Node>
<Create Type="A">
<Attr Name="Type1" Val="123"/>
<Attr Name="Type2" Val="Water"/>
<Attr Name="TypeZ" Val="2019-12-01T08:00:00"/>
</Create>
</Node>
<!-- I want XSD to throw error saying TypeZ is not allowed -->
I rectified xsd to solve all prob statements

As you can see I have a repeatable checkbox container, who have 3 more element inside
structure view
I can get and iterate records list, but no idea how can I get a list with all checkboxes and iterate for their elements inside
DynamicQuery getRecordsetIdQuery = DDLRecordSetLocalServiceUtil.dynamicQuery()
.setProjection(ProjectionFactoryUtil.distinct(ProjectionFactoryUtil.property("recordSetId")))
.add(RestrictionsFactoryUtil.ilike("name", courseSetName));
DynamicQuery getDdlRecordListQuery = DDLRecordLocalServiceUtil.dynamicQuery()
.add(PropertyFactoryUtil.forName("recordSetId").in(getRecordsetIdQuery));
JSONArray courseList = JSONFactoryUtil.createJSONArray();
List ddlRecordList = DDLRecordLocalServiceUtil.dynamicQuery(getDdlRecordListQuery);
if (ddlRecordList != null && ddlRecordList.size() > 0) {
int ddlRecordListSize = ddlRecordList.size();
for (int i = 0; i < ddlRecordListSize; i++) {
DDLRecord ddlRec = (DDLRecord) ddlRecordList.get(i);
Field active = ddlRec.getField("Active");
...
Do you can help me with some ideas please ?
I have three fields. solution for how to get repeated Field in portlet.
1.LanguageName (Parent and Repeated Field)
2. DocumentLinkLabel (Repeated Field)
3. DocumentLink (Child Field)
for (JournalArticle journalArticle : journalArticleList) {
Document docxml;
try {
docxml = SAXReaderUtil.read(journalArticle.getContent());
Node root = docxml.getRootElement();
List<Node> languageList = root.selectNodes("/root/dynamic-
element[#name='LanguageName']");
for (int i = 0; i < languageList.size(); i++)
{
Node languageNode = languageList.get(i);
String languageName =languageNode.selectNodes("/root/dynamic-
element[#name='LanguageName']/dynamic-content[#language-
id='en_US']").get(i).getText();
System.out.println("language Name : "+ languageName);
List<Node> documentLinkLabelList =languageNode.selectNodes("dynamic-element[#name='DocumentLinkLabel']/dynamic-element[#name='DocumentLink']");
for (int j = 0; j < documentLinkLabelList.size(); j++) {
Node languageNode1 = documentLinkLabelList.get(j);
String documentLinkName =languageNode.selectNodes("dynamic-
element[#name='DocumentLinkLabel']/dynamic-content[#language-id='en_US']").get(j).getText();
System.out.println(" document Link Lable Name : "+ documentLinkName);
String linkNameList=languageNode1.selectNodes("//dynamic-
element[#name='LanguageName']["+(i+1)+"]/dynamic-
element[#name='DocumentLinkLabel']/dynamic-element[#name='DocumentLink']/dynamic-content[#language-id='en_US']").get(j).getText();
System.out.println(" linkNameList : "+ linkNameList);
}
}
} catch (DocumentException e) {
e.printStackTrace();
}
}
You can't explicitly access DDList content in code. You have to get the xml of the record from the database and use SAXParserUtil and XPath expressions to read the values.
it´s possible to generate a WSDL using the JAX-WS client code only?
I have a legacy client code without wsdl inside, just remote wsdl uri, and I need to create mockservices for that client code and I need the WSDL to create this mocks.
Any idea?
For purpose of creating a mock/stub service provider, I believe it is better to download the original WSDL if you can. The risk with generating a WSDL from client generated code is the definite possibility the generated WSDL doesn't exactly match the original, which defeats the purpose of mocking or stubbing.
However, here were the steps I used to generate a WSDL from a generated JAX-WS client. I did have to hand-code an implementation class.
Original WSDL: http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL
Generate JAX-WS client:
wsimport -extension -keep http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL
This creates the sample JAX-WS client, which includes a generated service endpoint interface (SEI): com.cdyne.ws.weatherws.WeatherSoap
Oddly enough, we need an implementation class to run wsgen to generate a WSDL. I manually created an implementation class, declared it to implement the SEI, then copied all methods from the interface definition and gave each a return null; implementation.
package com.cdyne.ws.weatherws;
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;
import javax.xml.bind.annotation.XmlSeeAlso;

import javax.xml.ws.ResponseWrapper;
#WebService(name = "WeatherSoap", targetNamespace = "http://ws.cdyne.com/WeatherWS/")
public class WeatherSoapStubImpl implements WeatherSoap {
/**

*/
#WebMethod(operationName = "GetWeatherInformation", action = "http://ws.cdyne.com/WeatherWS/GetWeatherInformation")
#WebResult(name = "GetWeatherInformationResult", targetNamespace = "http://ws.cdyne.com/WeatherWS/")
#RequestWrapper(localName = "GetWeatherInformation", targetNamespace = "http://ws.cdyne.com/WeatherWS/", className = "com.cdyne.ws.weatherws.GetWeatherInformation")
#ResponseWrapper(localName = "GetWeatherInformationResponse", targetNamespace = "http://ws.cdyne.com/WeatherWS/", className = "com.cdyne.ws.weatherws.GetWeatherInformationResponse")
public ArrayOfWeatherDescription getWeatherInformation() {
return null;
}
/**

*

#WebMethod(operationName = "GetCityForecastByZIP", action = "http://ws.cdyne.com/WeatherWS/GetCityForecastByZIP")

#ResponseWrapper(localName = "GetCityForecastByZIPResponse", targetNamespace = "http://ws.cdyne.com/WeatherWS/", className = "com.cdyne.ws.weatherws.GetCityForecastByZIPResponse")
public ForecastReturn getCityForecastByZIP(
#WebParam(name = "ZIP", targetNamespace = "http://ws.cdyne.com/WeatherWS/")
String zip) {
return null;
}
/**
* Allows you to get your City's Weather, which is updated hourly. U.S. Only
*

*/
#WebMethod(operationName = "GetCityWeatherByZIP", action = "http://ws.cdyne.com/WeatherWS/GetCityWeatherByZIP")
#WebResult(name = "GetCityWeatherByZIPResult", targetNamespace = "http://ws.cdyne.com/WeatherWS/")
#RequestWrapper(localName = "GetCityWeatherByZIP", targetNamespace = "http://ws.cdyne.com/WeatherWS/", className = "com.cdyne.ws.weatherws.GetCityWeatherByZIP")
#ResponseWrapper(localName = "GetCityWeatherByZIPResponse", targetNamespace = "http://ws.cdyne.com/WeatherWS/", className = "com.cdyne.ws.weatherws.GetCityWeatherByZIPResponse")
public WeatherReturn getCityWeatherByZIP(
#WebParam(name = "ZIP", targetNamespace = "http://ws.cdyne.com/WeatherWS/")
String zip) {
return null;
}
}
Compile the stub implementation class.
javac com/cdyne/ws/weatherws/WeatherSoapStubImpl.java
Generate the WSDL. This is where command line switches can be used to try to get as close as possible to the original.
wsgen -keep -cp . com.cdyne.ws.weatherws.WeatherSoapStubImpl -wsdl:Xsoap1.2 -extension -inlineSchemas
(creates WSDL in current dir):

Create the stub or mock service with tooling such as SOAPUI
With this approach and simple service interface I was able to successfully send SOAP messages with the client to a mock service provider created in SOAPUI created with the generated WSDL.
Here is an example of wsimport-generated service stub method:

By default wsimport has generated service method with Synonyms class as return type rather than GetSynonymResponse class.
My question is whether this is customizable - is there a possibility to make wsimport generate service methods with different signatures, particularly having GetSynonymResponse class as return type?
Thanks in advance,
Valery
Found how this is configurable:
The feature called "WrapperStyle" should be disabled to make generated method return xxxResponse type.
This is accomplishable by providing -b parameter to wsimport like
wsimport" -b binding.xml ContactService.wsdl
with binding.xml contents as
<jaxws:bindings wsdlLocation="ContactService.wsdl"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
xmlns:jaxws="http://java.sun.com/xml/ns/jaxws"
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb">
<!-- Turn off wrapper style Java method signature generation -->
<jaxws:enableWrapperStyle>false</jaxws:enableWrapperStyle>
</jaxws:bindings>
I am using Amazon Product Advertising API (amazon-ecs) gem, but I am using the item_lookup method instead of item_search, which is the only one documented.
I am looking to return the item TradeInValue but I am confused as to how to do that. It is clearly being returned, but I am not sure how to parse it.
This is the call:
Amazon::Ecs.item_lookup('9780521153348', :response_group => 'ItemAttributes', :id_type => 'ISBN', :search_index => 'Books')
And this is the return, which I am not sure what to do with. The methods in amazon-ecs don't seem to work for item_lookup and XPath isn't working either:

Okay, I figured it out. I was trying to treat item_lookup as a single return value, rather than a hash the way search is returned.
item_lookup is basically the same as item_search:
res = Amazon::Ecs.item_lookup('9780521153348', :response_group => 'ItemAttributes', :id_type => 'ISBN', :search_index => 'Books')
res.items.each do |item|
puts item.get('ItemAttributes/TradeInValue/FormattedPrice')
end
