Heliocentric Trajectories Web Services Developer's Kit

Introduction

The Heliocentric Trajectories Web services provide heliocentric trajectory information for a number of objects. While HelioWeb provides heliocentric trajectory information through an HTML-based user interface, these Web services provides a distributed programming interface to the same information.

Figure 1.1-1 shows a simplified view of the software architecture.

**Table 1.1-1. Component Description**
Component	Description	Source
Client Program	A client program. It may use the HeliocentricTrajectories unique artifacts and JAX-WS or some other runtime support library.	Developed by any organization wishing to use the Web services.
HeliocentricTrajectories Unique Client Artifacts	HeliocentricTrajectories unique client wrapper to the JAX-WS library. This code is generated by the wsimport tool included with the Java EE.	Provided in the Web services SDK by the group which developed the HeliocentricTrajectories Web services.
JAX-WS runtime	JAX-WS runtime which handles the actual formatting and sending and receiving of SOAP messages.	Java EE 5 or Java SE 6.
Heliocentric Trajectories Unique Server artifacts	HeliocentricTrajectories unique server wrapper to the JAX-WS library. This code is generated by the wsgen tool included with the Java EE.	Automatically generated by the Web Application Server when the HeliocentricTrajectories Web services are deployed.
HeliocentricTrajectories Web services	The implementation of the HeliocentricTrajectories Web services. This component interfaces with existing HelioWeb HTML interface to fulfill Web service requests.	Delivered with the HeliocentricTrajectories Web services by the group which developed the HeliocentricTrajectories Web services.

Description

This developer's kit contains the development files required to develop a client application that uses the HeliocentricTrajectories web services. This document also provides information to help a developer in developing an HeliocentricTrajectories web service client. Specifically, the kit contains the following:

A URL to the WSDL file describing the Web Services which you can use with any development platform that supports web services
A Java library that provides a convenient API to the Web Services
Documentation that describes the Heliocentric Trajectories Web Services API and the Java library
Example code that demonstrates using the HeliocentricTrajectories web services

This document assumes the reader is already familiar with distributed programming concepts and a programming language but previous knowledge of web services is not required.

Issues common to all types of clients

This sections describes issues related to utilizing the HeliocentricTrajectories Web Services API from any type of client. That is, the issues described in this section apply to all clients irrespective of the programming language/tools used to develop the client or runtime enviroment in which the client is executed. The following issues are common to all types of clients:

Changes to the Web services
HTTP User-Agent header
Server resource limits

These issues are described below.

Changes to the Web services

We strive not to make changes to the Web services that would cause client applications to fail. Major functional changes and changes to the Web services' public interface are only made at major releases (e.g., R1.0 to R2.0) and not at minor releases (e.g., R1.0 to R1.1). We provide advanced notice of major changes and leave the existing Web services available for a transition period after the new release has been deployed (at a URL that is different from the previous major release). Announcements of both major and minor releases are made to the spdf_announcements e-mail list. All client developers are encouraged to subscribe to this e-mail list so they are aware of changes. Otherwise, it is possible that Web service changes could be made that adversely a developer's client without the developer knowing about the change.

HTTP User-Agent header

You are strongly encouraged to have your client set the HTTP User-Agent header (RFC 2068) to a value that identifies your client application in each Heliocentric Trajectories Web Service request that it makes. This will allow us to measure the usefulness of these services and justify their continued support. It isn't too important what value you use but it's best if it uniquely identifies your application. The specifics of how to do this in the client varies depending upon the programming language and support libraries used for the client. The example Java client described below contains the code required to set the header in a Java/JAX-RPC client. If you are unable or unwilling to set the User-Agent value in your client but still want us to know that your client uses the HeliocentricTrajectories Web Services, you may send a description of your client and any comments about the HeliocentricTrajectories Web Services to SPDF Support.

Server resource limits

There are server computer resource limits imposed on the Heliocentric Trajectories Web services. While these limits are not expected to be limiting for legitimate requests, making requests for a long period of time or for a large number of spacecraft can exceed these limits and result in a "request exceeded computer resource limits" exception. A client may want to be prepared to deal with such occasions.

How to use the WSDL file

The WSDL file provides a standard description of HeliocentricTrajectories web services. The file is available from https://sscweb.gsfc.nasa.gov/WS/helio/1/HeliocentricTrajectoriesService?wsdl. You may want to save the file to your computer's disk for later use.

Note
Depending upon your browser's XML capabilities and how it handles an XML file that doesn't contain any style information, you may need to use the browser's "view source" option to view the WSDL in the browser. Recent versions of Internet Explorer and Mozilla will have no problem displaying the WSDL. Alternately, you may force the browser to save the WSDL file and view it using another application. The file should be viewable in a simple text editor.

Recent versions of Internet Explorer and Mozilla will have no problem displaying the WSDL. Alternately, you may force the browser to save the WSDL file and view it using another application. The file should be viewable in a simple text editor.

Many programming languages now understand WSDL and can use this file to automatically invoke Web services. For example, the WSDL can be imported into .NET, converted into Java code using the JAX-WS wsimport tool, or used directly by Perl SOAP::Lite. Refer to your particular development tools' documentation to learn how to use the provided WSDL file to develop a client application. If you are developing your client in a language other than Java or don't want to use the included Java library, then you must use the WSDL and can ignore the next section.

How to use the Java API

For convenience, we have included a Java library based upon JAX-WS. It is not necessary to use this library but it will be the easiest way for someone developing a Java client to access the Heliocentric Trajectories Web Services. You may use the WSDL described above along with any other standards complying web service development tools to develop a client instead of using this library.

The Java API provides an easy to use, high level API for accessing the Heliocentric Trajectories web services. It was developed using JAX-WS 2.0. Here is a description of the Heliocentric Trajectories Web services Java API . In order to use the Java library include in this SDK, you must already have a Java 1.5 development environment with the JAX-WS 2.0 run-time class libraries or Java 1.6 which includes the JAX-WS run-time class libraries.

The helioTrajectoriesWs-client.jar library provided with this kit contains an application that can be used to test the client run-time environment with the web services. To use the test client, use the equivalent of the following, single line command for your environment:

java -jar helioTrajectoriesWs-client.jar https://sscweb.gsfc.nasa.gov/WS/helio/1/HeliocentricTrajectoriesService?wsdl

This should produce output similar to the following:
