I've developed a solution based in NanoHTTPD called
NanoXFServer.
You can download it form
http://dianaydavid.com/download/nanoxfserver.zip
Basically is a tiny
Java Webserver that supports PUT Method, so you can save XForms
submissions locally. Take a look to instance-save-test.xforms
Sadly,
my wordpress based website, has been shut down, with the full
documentation. But here is a transcript:
NANOXFSERVER
* WHAT IS
IT?
NanoXFServer is a really small web server based in Java that can
handle PUT and XML-URLENCODED-POSTXForms submission methods.
It´s
based in the smallest, fully functional WebServer available in
Java:
NanoHTTPD http://elonen.iki.fi/code/nanohttpd/ [1]
* WHY A WEB SERVER
FOR XFORMS?
If you are developing XForms using a javascript based
implementation
(probably XSLTForms), you must be facing two problems if
you want to
run your XForms locally:
* For security reasons,
javascript is disabled (fully or partially,
depending on your browser)
when you open a local file in your browser,
so your XForms won't work.
* There is no way of saving the XML Instance data to a local file
(for
security reasons also), so you need javscript tricks or a full
web
server if you want to see the XForm data
The purpose of
NanoXFServer is to allow XForms to run locally for
testing (or maybe for
full local applications) without an Web Server
(like Apache or eXist-db)
* HOW IT WORKS?
The simplest way of using NanoXFServer is to copy
nanoxfserver.jar to
the folder where your XForms resides, and then run
it with the following
command:
JAVA -JAR NANOXFSERVER.JAR
Then point
your browser to http://localhost and you´ll get a listing of
the files
on your directory. Choose your XForms and it's running.
Take in
account that you'll need two prerequisites:
* You'll need Java JRE
installed on yout computer
* If you are using a client based XForms
Implementation (like XSLTForms)
you´ll need the appropiated files
(xsltforms folder) and processing
instructions in your XForms, in order
to get it running
For saving your instances locally, use the PUT
submission method,
and specify a relative file name in the ACTION or
RESOURCE attribute
of the submission element, like this:
<XF:SUBMISSION ID="DOPUT" RESOURCE="DATA/PUTDATA.XML" METHOD="PUT" />
XML Instance will be stored in a file named PUTDATA.XML under the DATA
folder
(the folder must exists)..
If you are using XSLTForms, you can
also use the XML-URLENCODED-POST method,
this way:
<XF:SUBMISSION
ID="DOPOST" RESOURCE="POSTDATA.XML"
METHOD="XML-URLENCODED-POST">
Using XML-URLENCODED-POST, the browser will show the
resulting
instance (useful for quick testing)
* WHAT CAN IT DO?
NanoXFServer
adds the following features to NanoHTTPD:
* Support for PUT
submission method.
* Support for XML-URLENCODED-POST submission
method
(supported in XSLTForms). * XML Instances are saved with UTF-8
file encoding
* Inhibits use of .. on instance saving.
* Serves the
following file extensions as etxt/xml: .xml .xsl .xslt .xsd
.xforms
*
Serves .xhtml files as application/xhtml+xml (not supported for
all
browsers)
Here is a complete list of features form the NanoHTTPD
web page:
* Only one Java file
* Java 1.1 compatible
* Released
as open source, Modified BSD licence
* No fixed config files, logging,
authorization etc. (Implement by
yourself if you need them.) * Supports
parameter parsing of GET and POST methods
* Parameter names must be
unique. (Adding support to multiple instance
of a parameter is not
difficult, but would make the interface a bit
more cumbersome to use.)
* Supports both dynamic content and file serving
* Supports file
upload (since version 1.2, 2010)
* Never caches anything
* Doesn't
limit bandwidth, request time or simultaneous connections
* Default
code serves files and shows all HTTP parameters and headers
* File
server supports directory listing, index.html and index.htm
* File
server supports partial content (streaming)
* File server supports
ETags
* File server does the 301 redirection trick for directories
without /
* File server supports simple skipping for files (continue
download)
* File server serves also very long files without memory
overhead
* Contains a built-in list of most common mime types
* All
header names are converted lowercase so they don't vary
between
browsers/clients
Hope this help you or at least bring new
ideas,
Bill
