Is it possible to pass schemalocation as relative path in wsdl? - import

I'm using WsdlPull library to parse the WSDL file.
Is it possible to provide relative path in the schemaLocation whiling importing external XSD inside WSDL?
e.g.
<types>
<xsd:schema xmlns="http://www.w3.org/2001/XMLSchema">
<xsd:import namespace="http://myprovider/namespace1/namespace1" schemaLocation="schema1.xsd"/>
</schema>
</types>

Schemas should be resolved relative to the containing document (in this case the WSDL's Url), so this should work. In fact we have WSDL files that do exactly what you appear to be trying to do.
However the implementation is given quite a lot of freedom during the resolution process (for example allowing it to transform the url causing it to load from a cache rather than the actual url).
As your positing this I assume this is not working?

Encoding a GPX file such that it's accepted by the /matchroute endpoint of the Here API

I am trying to call the resource /matchroute via a GET request.
However, I can't figure out how to encode the GPX file so that the resource accepts my request: I always receive HTTP error 400 as a response from the Here server.
As exemplary data I used the following file:
<?xml version="1.0"?>
<gpx version="1.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.topografix.com/GPX/1/0"
xsi:schemaLocation="http://www.topografix.com/GPX/1/0
http://www.topografix.com/GPX/1/0/gpx.xsd">
<trk>
<trkseg>
<trkpt lat="51.10177" lon="0.39349"/>
<trkpt lat="51.10181" lon="0.39335"/>
<trkpt lat="51.10255" lon="0.39366"/>
<trkpt lat="51.10398" lon="0.39466"/>
<trkpt lat="51.10501" lon="0.39533"/>
</trkseg>
</trk>
</gpx>
that I got from the this example.
I encoded this file using MATLAB's function matlab.net.base64encode which yielded the following base64-encoded string:

However, as stated before, the HERE server consistently responds with HTTP-error 400 to my request
https://rme.api.here.com/2/matchroute.json?app_id={app_id}&app_code={app_code}&routemode=car&file=...
where "..." equals the above mentioned base64-encoded string.
Question: Could anyone please provide a code sample showing how to encode the above mentioned GPX file correctly (ideally in MATLAB language) so that the /matchroute resource is able to respond?
Remarks:
If I use the base64 string

from this example the GET request works. However, I couldn't figure out how to reproduce this encoding myself so that I am able to encode my own data accordingly.

Looking at the two base64 strings I can tell you the fundamental difference between them - the first one (which doesn't work) is unescaped whereas the second one (which works) is.
You can convert between the two formats manually using various online tools like this one. The escaped version of the non-working base64 string, in case you want to test it, is:

I'm not an expert on this, but as I understand, you need to URL-encode strings only when you want to paste them as-is into the web path of your browser (read about "URL Params"). If you construct your HTTP requests the right way™ (by this I mean specify the headers of the request and the key-value pairs correctly), you shouldn't have to worry about URL-encoding at all, since the tool that you're using (in this case, MATLAB) should take care of the conversion for you.
Unfortunately, I cannot test this theory, as I have no access to the discussed API - but I am fairly certain that this would solve your problem.
I had the exact same problem.
The documentation seems to be incomplete. You can check here for additional information. Several ways I solved this:
Use filetype='CSV' or filtetype='GPX' in parameter. It says the filetype is guessed if passed, that is actually not true. After passing an XML file the API told me my file didn't look like a 'CSV'
Compression is OPTIONAL, I suggest to avoid it completely I could not find a suitable compression either. It works fine with plain base64 encoding.
I suggest to actually use CSV because the XML actually returns parsing errors.
In python
data='''latitude,longitude
51.10177,0.39349
'''
r = requests.get('https://rme.api.here.com/2/matchroute.json?app_id={APP_ID}&app_code={APP_CODE}&routemode=car&file={file}&filetype={filetype}'.format(
APP_ID=os.getenv('HERE_APP_ID'),
APP_CODE=os.getenv('HERE_APP_CODE'),
filetype='CSV',
file=base64.b64encode(data.encode()).decode()
))

Passing encoded XML content in SOAP envelop request in Java application

I'm developing a Java application where I need to make a web service request using SOAP protocol. In that SOAP envelop request, one of the XML attribute/property called content will hold the XML file itself like below:-
<n1:envelope>
<message>
<id>67872894892424</id>
</message>
<sender agency="GS1" scheme="tGLK">ur.0</sender>
<recipients>
<id agency="GS1" scheme="tGLK">test</id>
</recipients>
<content encoding="XML" extension="A" format="ATTP">
------
----
</content></n1:envelope>
I'm new to it and requires some assistance in clarifying my doubts. I'm using JDK1.8 and Apache CXF. How can I do marshaling/unmarshalling for this particular content attribute? Normal SOAP envelops request is easy to do it but not sure how to pass an encoded XML itself in SOAP request. Is there any reference links? Thanks
Your case is an example of including XML inside XML. Yes, XML could be included inside an SOAP(XML), there are two ways, though both means almost same thing.
Using CDATA encoding
<hello><![CDATA[<El><E2><E3 attr="D1">Text</E3></E2></El>]]></hello>
Converting the XML into text by replacing, < with <, " with &quote; and > with >
<hello><El><E2><E3 attr="D1">Text</E3></E2></El></hello>
To
<hello>>El<>E2<>E3 attr="D1"<Text>/E3<>/E2<>/El<</hello>
Hence, to include the XML inside SOAP, while adding the XML element, you need to follow either approach while marshaling/unmarshaling.

At least one WSDL with at least one service definition needs to be provided

I have defined my service on the WSDL file this way:
<wsdl:service name="guestbook">
<wsdl:port binding="tns:guestbookSOAP" name="guestbookSOAP">
<soap:address location="http://localhost:8080/soapguestbook"/>
</wsdl:port>
Still I am getting the following error message when running wsimport on it:
At least one WSDL with at least one service definition needs to be provided.
Is there anything else I need to add?
The problem in your case is that the definitions element is missing, which is like a root.
WSDL has a specific structure, for which the root element should be the DEFINITIONs, under it various other elements are present like types, messages, portType, binding, services etc.
The structure is like the below:
<definitions>
<types> data type definitions........ </types>
<message> definition of the data being communicated.... </message>
<portType> set of operations...... </portType>
<binding> protocol and data format specification.... </binding>
</definitions>
For the meaning of each WSDL element look into the link:

AXIS SOAP wsdlPortType

What do these parameters do and what are they used for?
<service name="...">
<parameter name="wsdlPortType" value="..."/>
</service>
Also, if anyone can explain the parameters wsdlServicePort, wsdlTargetNamespace, and wsdlServiceElement, that would be appreciated.
Axis 1.4 User's Guide:
When you deploy a service in Axis, users may then access your
service's URL with a standard web browser and by appending "?WSDL" to
the end of the URL, they will obtain an automatically-generated WSDL
document which describes your service.
Experimental results suggest that Axis is able to use a combination of the .wsdd deployment descriptor file and compiled Java .class files to generate the corresponding .wsdl for a given service. It's interesting to note that, for example, if you have a public method with a Generics return type such as Map, your generated .wsdl file will not contain the return type - it will contain "xsd:anyType" instead. I believe this is due to type erasure on the compiled .class file.
Anyway, the service options in the Axis .wsdd file (the parameters I referenced in my question such as wsdlPortType, wsdlServicePort, and wsdlTargetNamespace) are related to the .wsdl specifications. This can be inferred from the names themselves since they all contain 'wsdl' in them, but I wanted an explanation of what these parameters mean and I was unable to find relevant Axis documentation. Here are my findings:
wsdlPortType (portType): basically like a Java interface. Contains one "operation" element for each method name. Each "operation" contains "input" and "output" elements that are basically your input parameters and return parameter of the Java method.
wsdlServicePort (wsdl:binding) Associated with the portType. I think of it as a description of how to transmit the parameters for the portType. The spec has this to say:
A binding description component provides a framework for indicating
binding details for a portType description component. Binding details
SHOULD be used to indicate how messages MUST be formatted when they
are sent to or from the service. They SHOULD also be used to indicate
the transport protocol to be used to send the messages. A given
binding description component MUST NOT indicate more than one
protocol.
wsdl:service: Has a reference in it to the wsdl port binding (the implementation of the portType).
target namespace: Pretty much what I thought it was (same as a namespace anywhere else). It applies to all of the wsdl:definitions components, so anything in the wsdl file basically (wsdl:portType, wsdl:service, etc). There are a couple other rules that you can find in the spec though.
Problem:
When using Service?wsdl, the generated wsdl may not have
the same targetNamespace, portType, service element name, or
service port name as the original wsdl. This problem has
been reported by users and is a TCK issue.
Solution:
Four optional parameters are added to the deploy.wsdd and
queried by the JavaProvider (wsdlTargetNamespace, wsdlServiceElement,
wsdlServicePort and wsdlPortType).
Here is an example deploy.wsdd with the new parameters.
<!-- Services from AddressBookService WSDL service -->
<service name="AddressBook" provider="java:RPC">
<parameter name="wsdlTargetNamespace" value="urn:AddressFetcher2"/>
<parameter name="wsdlServiceElement" value="AddressBookService"/>
<parameter name="wsdlServicePort" value="AddressBook"/>
<parameter name="className" value="samples.addr.AddressBookSOAPBindingSkeleton"/>
<parameter name="wsdlPortType" value="AddressBook"/>
<parameter name="allowedMethods" value="*"/>
<parameter name="scope" value="Session"/>

RESTful way to return location information

I have written a REST server based on RESTEasy.
In some of the resources, collections of objects are returned instead of single objects: the method that responds to the URL "/users/{user_id}" returns a single "user" object, but the method that responds to the URL "/users" returns all users. In the former case, I can include an HTTP header "Content-Location: URL" (although this is redundant since the caller has the correct URL). In the latter case, each item in the returned collection has its own location. I was thinking of added an XML attribute to each item specifying its location:
<users>
<user location="/users/1234">
...
</user>
<user location="/users/5678">
...
</user>
</users>
Is there some conventional way of returning this information?
This is a very common practice when designing hypermedia APIs. It is also highly recommended. There is no official "right" way of doing it, however one media type that has very explicit rules as to how you can do it is hal. See http://stateless.co/hal_specification.html
In hal your document would look like:
<resource href="/users">
<resource rel="item" href="/users/1234">
...
</resource>
<resource rel="item" href="/users/5678">
...
</resource>
</resource>
I picked the term "item" because it has been psuedo standardized, but you could put your own link relation, there are just a few rules you should follow when identifying your own link relations. (See RFC5988 for details)
