speak.js.xsl -- DataPower talks

HermannSW Tags: javascript text-to-speech datapower speach xsl ‎ 4,096 Views

I am not sure whether this posting is just for fun, or whether useful solutions may be build based on it.

Today I searched with my son for text-to-speech Java libraries for him, there are several implementations available:
http://java.sun.com/products/java-media/speech/forDevelopers/jsapifaq.html#implementation

Later I thought on DataPower and text-to-speech, and joining DataPower with Java seemed difficult for me.

I searched for "text-to-speech Javascript" and found nice 100% clientside JavaScript solution speak.js:
http://syntensity.com/static/espeak.html

(works with Firefox and Chrome browsers)

This demo also includes the project page link for download.

Now I wanted to create a little "DataPower talks" demo.

The stylesheet should determine some useful box information and just "talk" the result, making use of speak.js.

Here is the HTML file response generated by stylesheet speak.js.xsl by using coproc2 tool:

$ echo "<x/>" | coproc2 speak.js.xsl - http://dp3-l3:2223 ; echo
<html><head><meta content="text/html; charset=UTF-8" http-equiv="Content-Type"><
script src="speakClient.js"></script></head><body onload="speak('DataPower talks
, product-id 92354BX, product XI50, device-name (unknown), serial-number 68A0342
, firmware-version XI50.3.8.2.13jh, reset-date 2012-08-14, reset-time 14:19:38 E
DT, ', { speed: 120 } )"><div id="audio"></div></body></html>
$

You can "hear" the result by opening this file with the three required JavaScript files in same directory eg. by opening it with Firefox.

<EDIT>... or you might want to "hear" into dp3-l3.talks.wav, also contained in the .zip file linked to at the end of this posting below ...</EDIT>

But that was a first auxiliary step only -- accessing the service via a GET request from a browser should make DataPower "talk".
This is the service I am talking about:

$ curl http://dp3-l3:2087 ; echo
<html><head><meta content="text/html; charset=UTF-8" http-equiv="Content-Type"><
script src="speakClient.js"></script></head><body onload="speak('DataPower talks
, product-id 92354BX, product XI50, device-name (unknown), serial-number 68A0342
, firmware-version XI50.3.8.2.13jh, reset-date 2012-08-14, reset-time 14:19:38 E
DT, ', { speed: 120 } )"><div id="audio"></div></body></html>
$

As can be seen it produces the same output, but the browser will request speakClient.js from DataPower (which will

request the two other required JavaScript files, speakWorker.js and speakGenerator.js), and then "talk".

So we need kind of a HTTP service for URIs starting with "/speak*" -- I made use of the solution of posting HTTPService.xsl.
For making that work the three JavaScript files have to be placed in "local:///DocRoot", that's it, see this screenshot:

Now DataPower talk service just is a

loopback XML Firewall
with request type XML
with "Process Messages Whose Body Is Empty" enabled (for GET requests)
the policy consisting of two rules as detailed below.

This are the two rules of the service:

1st rule:

match for "/speak*"
"Header Rewrite" action, "content-type" replaces all (".*") by "text/javascript"
(browsers do need this content type to work correctly)
"Transform" action with stylesheet from HTTPService.xsl posting

2nd rule:

match all (url="*")
"Transform" action with stylesheet speak.js.xsl

This is stylesheet speak.js.xsl:

You can find an analog recording of a sample DataPower talk in this 3.8MB .zip file, together with HTTPService.xsl and speak.js.xsl:
speak.js.xsl.zip

zip-copy.xsl

HermannSW Tags: datapower copy zip management xsl coproc2 archive ‎ 7,173 Views

DeveloperWorks DataPower forum thread "uploading the directory on XI50" asked for a solution

to copy files onto DataPower box "local:///" preserving the directory structure:

https://www.ibm.com/developerworks/forums/thread.jspa?threadID=432753

Stylesheet zip-copy.xsl shown below and attached here does the job and is a solution independent of client OS.

It is based on unzip-l.xsl posting and Accessing XML Management interface from within a stylesheet posting.
It makes use of "RemoveDir", "CreateDir" and "set-file" XML Management Interface commands.

The stylesheet requires a user "xmlmgmt" with password "terces" (you should change that) and SSL Proxy Profile "xmlmgmt-client-ssl".

A sample execution with test archive a.zip (attached here) is not spectacular.
It just works, and is mainly shown here on how to make use of zip-copy.xsl with coproc2 tool against coproc2nonxml endpoint (see slide 3 of this webcast):

$ coproc2 zip-copy.xsl a.zip http://dp6-l3:2224/default?delete=yes ; echo
<done/>
$ 
$ unzip -l a.zip
Archive:  a.zip
  Length      Date    Time    Name

        0  06-16-2012 16:51   a/

        0  06-16-2012 16:51   a/b/c/
        0  06-16-2012 16:54   a/b/d/
        9  06-16-2012 16:54   a/b/d/hello.xml
        0  06-16-2012 16:56   a/b/e
        8  01-20-2012 15:03   some.xml
        0  06-18-2012 09:40   aa/
---------                     -------
       17                     8 files
$

And this is stylesheet zip-copy.xsl:
