I have the following method that accepts xml and I do some data feeding with the content.
I am supposed to return a SOAP message as well, something along these lines:
<ow-e:Envelope revision='2.0' xmlns:ow-e='http://www.url.com/test-envelope'>
<ow-e:Header>
<ow-e:Properties>
<ow-e:SentAt>2004-12-14T13:54:36</ow-e:SentAt>
<ow-e:Topic>SOME_STRING</ow-e:Topic>
</ow-e:Properties>
</ow-e:Header>
</ow-e:Envelope>
So right now what I am doing is the following:
String some_string = "qwe";
String response = "";
response = "<ow-e:Envelope revision='2.0' xmlns:ow-e='http://www.url.com/test-envelope'><ow-e:Header><ow-e:Properties><ow-e:SentAt>2004-12-14T13:54:36</ow-e:SentAt><ow-e:Topic>" + some_string + "</ow-e:Topic></ow-e:Properties></ow-e:Header></ow-e:Envelope>";
return response;
Which is absolutely terrible. Any idea how I can actually make it more bearable? Using a framework is not an option at the moment.
This is the first time I am dealing with SOAP messages/responses and it feels like hell coming from REST. I probably need to create some kind of hierarchy to populate the values correctly, but I am not sure how it can be done just by using Java without any frameworks.
You mentioned using frameworks is not an option, but something more lightweight may be available in your platform:
JAXB. JAXB allows you to map Java classes to XML representations using annotations. It's far better than doing marshaling and unmarshaling by hand or by concatenating or parsing strings. With properly structured and annotated POJOs, JAXB can handle things for you. You might even be able to cheat and use xjc with your WSDL file to create annotated classes with the -wsdl option (experimental though).
SAAJ. Bluntly put, SAAJ is just like a specific builder and parser for SOAP messages. It will handle the structure and namespaces for you. Speaking of which...
... the example you are showing isn't really valid SOAP message. SOAP is a protocol. You need to properly format it and use the right namespaces otherwise you are just returning some XML messages that look like SOAP, but aren't.

I am trying to interact with a third party web service, who requires me to send a security token as a part of each request. The token is a node by itself, and I acquire it from the response of an initial call.
The web service endpoint is dotNet, and I have a Java client.
Apparently, the server side expects me to send the security token exactly like it was provided to me: literally the same string: so it won't do if its content has a different size, order, etc.
So, in SoapUI, everything works fine. There is a token in the response of the initial 'startSession' call, which I copy into the request of a next call.
But in Java (I tried JAX-WS and CXF generated code, both rely on JAXB) it doesn't work. I receive the token as an object after it is unmarshalled, and I use this object in the next call.
When marshalled and send, it is missing a namespace attribute in a subnode. The server side says it won't continue because the token is incorrect.
So, by using JAXB outbound logical handler functionality, I am able to add the missing namespace without any problems in the DOM source (I was also able to achieve this with a CXF interceptor).
The problem now is, that the attributes, when marshalled, are ordered in such a way that the result still not matches the provided token as it was before it was unmarshalled. Alhough it should not matter, the order of these attributes is crucial.
I have no idea how to solve this, unless it is possible to actually modify the output XML string. I even tried a dirty hack by removing all attributes from the subnode and replacing them with one attribute that visually looks the same; but then the outer two double quotes become single quotes...
I hope anyone has an idea. Because I have none.
Cheers.
UPDATE:
I should have mentioned that the attributes in question are namespace(d) attributes. The node should look like this:
<HawanedoSessionInfo xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.thecompany.com/Hawanedo/Business/v2.0c">
However, after using outbound JAXB handler to add the missing xmlns="...", my result looks like this:
<HawanedoSessionInfo xmlns="http://schemas.thecompany.com/Hawanedo/Business/v2.0c" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
In the HawanedoSessionInfo class, I used XmlType.proporder and #XmlAttribute like so:
#XmlType(name = "HawanedoSessionInfo", propOrder = {
"xsd",
"xsi",
"xmlns",
and some other non-attribute sub-elements..
private String xsd;
private String xsi;
private String xmlns;
#XmlAttribute(ns="http://schemas.thecompany.com/Hawanedo/Business/v2.0c")
public String getXsd() {
return xsd;
}
public void setXsd(final String xsd) {
this.xsd = xsd;
}
#XmlAttribute(ns="http://schemas.thecompany.com/Hawanedo/Business/v2.0c")
public String getXsi() {
return xsi;
}
public void setXsi(final String xsi) {
this.xsi = xsi;
}
#XmlAttribute
public String getXmlns() {
return xmlns;
}
public void setXmlns(final String xmlns) {
this.xmlns = xmlns;
}
So apparently the proporder option does not help in this case?
UPDATE 2:
Like I wrote in my answer, it now works. Based on this LINK,
in the HawanedoSessionInfo class I added:
#XmlCustomizer(HawanedoSessionInfoCustomizer.class)
I created the customizer class exactly as described in the linked page, and I added the jaxb.properties.
So I did two things:
1) I added my attributes to (the top of the already existing) propOrder attribute. I added the attributes as instance variables and created the getters/setters. I annotated the getters with XmlAttribute.
2) I implemented the XmlCustomizer solution.
Now comes the strange part. According to Fiddler, the order of the attributes is still not changed! But I must stress that this is now working, ONLY after implementing the Customizer. What is happening here? :)
So in principle you cannot control order of attributes in a standard way, but ....
Depending on jaxb /java version the order can be determined by alphabetical order of the names, the order of declaration.
You could try in your code if a) moving the fields around changes anything, b) renaming the fields (the XMLAttribute than have to map to original name).
If you are lucky, it will work. But of course it is a hack and will work till next jaxb/java update.
The JAXB providers (the actuall implementation can have extra features), that can be used to customized the marshalling process). For example I found that: https://community.oracle.com/thread/977397 abut eclipselink.
I am sure there was a way of intercepting the soap body before it is send or governing the data serialization before it is send. I can think how it was called but try to google the jaxws client customization. If you capture the whole soap message simple xslt transforamation could fix the attributes order.
I feel your pain. The whole point of using xml, jaxws and such is to make our life easier and then someone providers decide not to follow standards and you end up with a mess that you were trying to clean for few days. Good luck and maybe try to contact xml gurus from Eclipse Moxy
I am so happy right now, because I got it working and it only cost me a full week to do so...:) With help of #Zielu, I was pointed to this link with the EclipseLink XMLCustomizer solution as suggested by Blaise Doughan: XMLCustomizer solution
I took the code in my original question (underneath 'UPDATE') and added the exact solution as suggested. Not sure if it is all necessary, but it works. Thanks guys.
It's possible you can control the order by using,
#XmlType (propOrder={"prop1","prop2",..."propN"})
I'm using jackson-module-jsonSchema and jsonschema2pojo API.
Brief explanation: I'm trying to json-schemify my server's Spring controller contract objects (objects that the controllers return and objects that they accept as parameters) and package them up to use with a packaged retrofit client in order to break the binary dependency between the client and server. The overall solution uses an annotation processor to read the Spring annotations on the controller and generate a retrofit client.
I've got it mostly working, but realized today I've got a problem where generic objects are part of the contract, e.g.
public class SomeContractObject<T> {
...
}
Of course, when I generate the schema for said object, the generic types aren't directly supported. So when I send it through the jsonschema2pojo api I end up with a class like so:
public class SomeContractObject {
}
So my question is simple but may have a non-trivial answer: Is there any way to pass that information through via the json schema to jsonschema2pojo?
I've been looking at the couchbase-java-client project and wondering whether it's possible to use it inside of a dropwizard project.
It seems like it'd be a natural fit, because couchbase is basically a JSON database, but the java client doesn't seem to be compatible with Jackson. As far as I can tell, the couchbase client library includes its own internal implementation of a JSON library that's incompatible with all the other java JSON libs out there, which is really weird.
I found a JacksonTransformers class that looked promising at first. But upon closer inspection, the library is using a shaded version of Jackson (with a rewritten package of com.couchbase.client.deps.com.fasterxml.jackson.core).
Anyhow, since dropwizard uses Jackson and Jersey for marshalling JSON documents through the REST API, what's the least-friction way of using the couchbase-java-client library? Is it even possible in this case?
It is definitely possible to use Couchbase with Dropwizard. The client SDK provides JSON manipulation objects for the developer's convenience but it also allows for delegating JSON processing to a library like Jackson or GSON.
Take a look at the RawJsonDocument class here.
Basically, you can use a Stringified JSON (coming out of any framework) to create one of those objects and the client SDK will understand it as a JSON document for any operation i.e.:
String content = "{\"hello\": \"couchbase\", \"active\": true}";
bucket.upsert(RawJsonDocument.create("rawJsonDoc", content));
It should be possible to make this work.
Client requests to dw server for Resource Person.
DW server requests to couchebase, gets a Pojo back representing Person or JSON representing person.
If it's JSON, create a POJO with Jackson annotations in DW and return that to client
If it's a special couchebase pojo, map that to a Jackson pojo and return to to client
A solution based on #CamiloCrespo answer:
public static Document<String> toDocument(String id, Object value,
ObjectMapper mapper) throws JsonProcessingException {
return RawJsonDocument.create(id, mapper.writeValueAsString(value));
}
Keep in mind, that you can't use a simply maper, like ObjectMapper mapper = new ObjectMapper(), with Dropwizard.
You can get it from Environment#getObjectMapper() in the Application#run() method, or use Jackson.newObjectMapper() for tests.
An example of using:
ObjectMapper mapper = Jackson.newObjectMapper();
User user = User.createByLoginAndName("login", "name");
bucket.insert(toDocument("123", user, mapper));
I'm having a problem where my C# client can't parse the data from my webservice in Glassfish.
I have a WSDL and XSD for my webservices as follows:
http://www.consorciovivedigital.com:8080/ServicioInterventoria/ServicioInterventoria?WSDL
http://www.consorciovivedigital.com:8080/ServicioInterventoria/ServicioInterventoria?xsd=1
And I'm using the next C# client to test this webservice:
using System;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using ServicioInterventoria;
public partial class _Default : System.Web.UI.Page
{
ServicioInterventoria.ServicioInterventoria proxy;
protected void Page_Load(object sender, EventArgs e)
{
proxy = new ServicioInterventoria.ServicioInterventoria();
ResultadoMensualIC[] res = proxy.ObtenerResultadosMensuales("Intv12", "2014-07-07T08:08:08");
System.Diagnostics.Debug.WriteLine(res.Length);
System.Diagnostics.Debug.WriteLine(res[0].FechaCorte);
}
}
The problem is that when I execute this code, the res array has the amount of objects that should have, but each value of each object has the default value instead of the correct value. I used Fiddler to check the traffic and it receives the correct SOAP response with the correct data, but it seems that my C# client doesn't know how to parse the data.
I checked with a Java client, and I can get the correct data without any problems, and seems that my C# it's the only one giving problems with this.
Maybe there is a problem with the targetNamespace in the SOAP response, but I don't understand why works correctly in Java but in C# just puts default values.
Anyone have any idea what could be the problem?
If someone needs more information about it, let me know
Thanks beforehand
I solved last week. The problem was that the SOAP response didn't put the namespace for each attribute, then, the C# client doesn't know how to match this (seems like a limitation of C#). And, the other problem was the order of the SOAP response, because, the C# client was expecting each object as was defined in the WSDL, but the response it's ordered alphabetically, in this way, the C# client, doesn't match correctly each attribute.
I did some modifications to the client. First, in each model, for each attribute I added the namespace, something like this:
#XmlElement(name = "IdInterventor", namespace = "http://ws.bigdatasolutions.co/")
public String getIdInterventor() {
return IdInterventor;
}
With this, the SOAP response always puts the namespace for each attribute, which was neccesary for the C# client.
After that, at the beginning of each model class I add this tag, to define the order as defined in the WSDL and expected for the C# client.
#XmlRootElement(name = "AspectosFinancieros")
#XmlType(propOrder={"idInterventor", "numeroContrato", "ano", "valorContratoOperador", "fechaFirmaContrato",
"valorAdicion", "fechaProrrogaAdicion", "valorDesembolso", "fechaPagoDesembolso",
"valorAnticipo", "fechaAnticipo", "valorUtilizacion", "numeroActaAprobacion",
"fechaUtilizacion", "valorRendimiento", "fechaRendimiento", "numeroComprobanteRendimiento",
"valorComision", "fechaComision", "valorGastosAdministrativos", "fechaGastosAdministrativos",
"nombreFiducia", "numeroContratoFiducia", "fechaContratoFiducia", "fechaProrrogaAdicionFiducia",
"marcaTiempo"})
public class AspectosFinancieros {
I checked the expected order in the auto generated class in the C# client.
I hope someone find this useful.
I am using com.ctc.wstx.stax.WstxOutputFactory to generate XML.
I am running wstx-asl-3.2.4
I need to start validating the generated XML against a W3 Schema.
When I create an instance of org.codehaus.stax2.validation.XMLValidationSchemaFactory like this
private final static XMLValidationSchemaFactory xsdFact=
XMLValidationSchemaFactory.newInstance(XMLValidationSchema.SCHEMA_ID_W3C_SCHEMA);
I get the error
javax.xml.stream.FactoryConfigurationError: No XMLValidationSchemaFactory implementation class specified or accessible (via system property 'org.codehaus.stax2.validation.XMLValidationSchemaFactory.w3c', or service definition under 'META-INF/services/org.codehaus.stax2.validation.XMLValidationSchemaFactory.w3c')

I can see that woodstox is bundled with a DTD parser only.
I found this article
which contains the unhelpful instruction
Get an instance of XMLValidationSchemaFactory that knows how to parse schemas of the type you need (RelaxNG == rng for this example).
I have been looking at the Sun Multi-Schema XML Validator which is supposed to contain the bits necessary to bolt on to the XMLSchemaValidation factory.
It looks like I might be able to use com.sun.msv.reader.xmlschema.XMLSchemaReader
to write my own instance of XMLValidationSchemaFactory and get it to work this way.
My question is; do I really have to do this, or is there a pre-existing w3c schema factory that I have failed to find?
Perhaps it would be simpler just to validate the XML after I have generated it.
What are the views on this ?
I've upgraded to Woodstox 4.0.8, W3CSchemaFactory comes bundled and its all good.
