AB: Space and Earth scientists increasingly require data products from multiple sensors. Frequently these data are widely distributed and each source may have very different types of data products. For instance a single space science research project can require data from more than one instrument on more than one spacecraft, data from Earth based sensors and results from theoretical models. These data and model results are housed at many locations around the world. The location of the data may change with time as spacecraft are complete their missions. Unless care is taken in providing access to these data, using them will require a great deal of effort on the part of individual scientists. Today's data system designers are challenged to link these distributed sources and make them work together as one. One approach to providing universal support is to base the core functionality of each data provider on common technology. An emerging technology platform is Sun's Java Application Server. With an application server approach all services offered by the data center are provided through Java servlets that can be invoked through the application server while responding to a request for a specific URL. The benefits of using an application server include a well established framework for development, broad corporate support for the technology and increased sharing of implementations between data centers. We will illustrate the use of an application server by describing the system currently being deployed at the Planetary Plasma Interactions Node of NASA's Planetary Data System.
