Introduction
8/15/2019 - The elandings system has had public SOAP webservices available for use since ~2012. The 2012 webservices make use of older technology that make them them challenging to work with. Some of these technologies are likely to be retired from out from under us in the coming years, as Java upgrades.
The 2012 webservices require that you get an XML XSD definition from elandings staff, so that you can parse XML responses into Java or C# Objects.
The 2012 webservices make use of long lists of unnamed arguments. For example findUserLandingReports_001() has 25 arguements, that could appear to the developer as "arg1, arg2, arg3..." These long lists are arguements are hard for developers to work with.
The 2019 Webservices attempt to address these weaknesses.
The 2019 Webservices WSDL includes the XML XSD definition, so that Java or C# can automatically generate the Object classes for you.
The 2019 Webservices allow you to pass Objects with named elements to represent the complex list of arguments. These objects tend to be far easier to understand, think about and work with. This also allows IDEs to offer code completion recommendations to get and set values by name
The 2019 Webservices make use of updated libraries that should be safe as Java upgrades in the near future.
We would encourage 3rd-party systems to migrate to the 2019 webservices sooner rather than later. This will allow eLandings and our partners to be better positioned to navigate the changing seas of Java.
WSDL Locations
As with the 2012 Public Webservices, the 2019 Public Webservices have three environments: TEST, TRAINING and PRODUCTION
TEST
https://elandingstest.alaska.gov/elandings/ReportManagementV1Service?wsdl
TRAINING
https://elandingst.alaska.gov/elandings/ReportManagementV1Service?wsdl
PRODUCTION
https://elandings.alaska.gov/elandings/ReportManagementV1Service?wsdl
Credentials
Just like the 2012 Public webservices, the 2019 Public webservices require that you have a user_id and password. Processors are able to create the user_id and password for 3rd party contractors in production. In Test and Training, an eLandings support person can create the user_id and password.
Unlike the 2012 Public webservices, the 2019 Public webservices require an application id GUID. An elandings support person can create the applicaiton id GUID to identify your company.
Your application id GUID will be different for TEST, TRAINING and PRODUCTION.
Example
In this example we are using Apache Netbeans 11.0.
Before running netbeans, edit the /etc/netbeans.conf to include:
-J-Djavax.xml.accessExternalSchema=all
For more details see https://netbeans.org/kb/docs/websvc/jax-ws.html
Create a new project of type Web Application
Create a new class of type Web Service from WSDL
Note: this will not be visible if you have not edited your netbeans.conf file
https://elandingstest.alaska.gov/elandings/ReportManagementV1Service?wsdl
Netbeans will generate the elandings.java class
Now Create the content of the MyClient.java class

} catch (ServiceException_Exception ex) {
Logger.getLogger(MyClient.class.getName()).log(Level.SEVERE, null, ex);
}
}
}//End of Class
Get a user id and password from elandings support or a processor (if working against production).
In this example we will attempt to pull a landing report that we know exists from elandings test for the user tturbot.
If we run our file we should get an output of:
INFO: Landing Report ID: 18378245 last edited by AMARX
