Servlet Interface (Slvxmlservlet); Writing An Interface To The Servlet - Paradyne OpenLane SLM 5.5 Administrator's Manual

B. Using XML to Produce Reports

Servlet Interface (SlvXmlServlet)

The XML report servlet can be found at:
The SlvXmlServlet servlet accepts a report request in XML and generates a report
in a specified format. The output is sent to the browser window. XML output can
optionally be transformed into different formats by an XSL Transformation.
There is a sample Web page to demonstrate the use of the servlet at
/opt/pdn/OpenLane/samples/xml/reports/xmlentry.html. You can
run the sample page from the URL
http:// your.domain.name /OpenLane/xmlentry.html when OpenLane is
running.
The easiest way to try the sample Web page is to open an XML report request file,
select and copy the text, and paste it into the Web page. Sample XML report
requests can be found in the following directories:

Writing an Interface to the Servlet

The servlet expects a HyperText Transfer Protocol (HTTP) post with up to three
parameters:
T

B-2
/opt/pdn/OpenLane/OLServlets/pdn.webcgi.SlvXmlServlet
/opt/pdn/OpenLane/samples/xml/reports/DeviceReports/Requests
/opt/pdn/OpenLane/samples/xml/reports/SlvReports/Requests
XmlReportRequest. The first and only mandatory parameter is
XmlReportRequest, which contains the report request in XML format.
OutputClassOrMime. The post may also contain a parameter called
OutputClassOrMime, which tells a Web browser how to interpret the reply for
viewing. This usually matches the output type specified in the report request,
but does not have to. For example, you may want to view an HTML/JavaScript
report as ASCII by using text/plain as the Multipurpose Internet Mail Extension
(MIME) type. The normal reply types for the supported report formats are
shown in the following table:
Output
DEFAULT (not specified)
and errors
XML
HTML/JavaScript
CSV
XslRequest. When the requested report output type is XML, the post
optionally may also contain a parameter called XslRequest, which contains an
XSL Transformation to apply.
