When creating MATLAB® files that rely on a web service, consider the following:
A server issues a time-out error. Repeat the MATLAB command.
Internet performance might make your application performance unpredictable.
Conventions and established procedures for services and related technologies, like WSDL and SOAP, are still evolving. You might find inconsistencies or unexpected behavior when using a web service.
A service might change over time, which can impact its usage and results in MATLAB.
A server issues other unrecoverable errors.

You can achieve better performance if you create a local copy and use the local copy instead of the version at the URL.
wsdlURL = ... ['http://basemap.nationalmap.gov/arcgis/services/USGSImageryOnly/MapServer?wsdl']; wsdlFile = 'USGSImageryOnly_MapServer'; if ~exist(wsdlFile,'file') websave(wsdlFile, wsdlURL) end
Use this strategy when you do not need immediate access to data at the URL.
Once you access a service from MATLAB using the generated client code, you might get Java® errors if:
The WSDL for the service changes and you run
matlabl.wsdl.createWSDLClient again for the same
service in the same MATLAB session.
You try to access the service using the regenerated code.
These errors are likely to occur if you modify the service between successive
If you change a service you already accessed or generate the class files in another location, restart MATLAB.
