action as input for a generator ??
hi
imagine the following scenario:
i have an xml-src which i have to enrich with
different
elements depending on the input document. with other
words the input xml will scale my process. in this
process i have to call different methods not driven
by cocoon but another underlaying system.
so i was thinking of using an action which will take
the input src and after processing it, it will return
the final document for transformation and
serialization
controled by the sitemap.
now my question(s):
is it possible to use an action as the input for
a generator or do i have to write my own generator?
i also thought of xsp, but i think it is to complex
to do it this way. i want to separate the logic which
processes the input as an autonomic module.
fyi: before i only used actions to manage formdata,
e.g.
manipulating xml-files depending on formdata. but now
i have no real file i can write to - so i have to
manipulate it to transform and serialize it directly
afterwards.
it would be very nice if somebody could give me an
advice how a solution can look like!!
thanks in advance !!
daniel

It worth considering writing own transformer then. By example of session
transformer, SQL, LDAP, etc.

just an idea : you have your xml file, you transform it with xslt, and your
stylesheet calls some java beans you use through xalan java extension. have
a look on Apache's xalan-j page.
Globally : you have a namespace for "java",
you use your beans this way :
<xsl:variable name="mybean"><xsl:value-of
select="java:package.MyBean.new()"/></xsl:variable>
then to call a function :
<xsl:value-of select="myfunction($mybean,$arg0,$arg1)"/>
given that the parameters (arguments) are defined as xsl variables.
HTH but this is sometimes VERY useful because java is roughly quicker to
execute that xslt...
My 2 cents ;-)
