Actions, pipelines, javabeans...
Hi,
I have created an action which returns parameters to a pipeline based
on a users login details. I want these details to persist for the du
ration of a user session and wanted to know how to store the values
passed into the pipeline into a JavaBean instead. At the moment I have
the parameters coming into my action as so:
1. pipeline
<map:match pattern="user-details">
<map:act type="get-detail2">
<map:parameter name="user" value="{request-param:user}" />
<map:parameter name="pass" value="{request-param:pass}" />
<map:generate type="file" src="content/main.xml" />
<map:transform src="style/main.xsl">
<map:transform src="style/main.xsl">
<map:parameter name="first_name" value="{first_name}" />
<map:parameter name="last_name" value="{last_name}" />
<map:parameter name="address1" value="{address1}" />
<map:parameter name="address2" value="{address2}" />
<map:parameter name="address3" value="{address3}" />
<map:parameter name="postcode" value="{postcode}" />
<map:parameter name="country" value="{country}" />
<map:parameter name="email" value="{email}" />
<map:parameter name="home_telephone" value="{home_telephone}" />
<map:parameter name="mobile_telephone" value="{mobile_telephone}"
/>
<map:parameter name="date_joined" value="{data_joined}" />
</map:transform>
<map:serialize type="html" />
</map:act>
and are passed into the pipeline from the Action as so:
2. Action
map.put("user_id", rs.getString(1));
map.put("first_name", rs.getString(2));
map.put("last_name", rs.getString(3));
map.put("address1", rs.getString(4));
map.put("address2", rs.getString(5));
map.put("address3", rs.getString(6));
map.put("postcode", rs.getString(7));
map.put("country", rs.getString(8));
map.put("email", rs.getString(9));
map.put("home_telephone", rs.getString(10));
map.put("mobile_telephone", rs.getString(11));
map.put("date_joined", rs.getString(12));
and then into my xsl page as so
3. xsl
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:param name="user_id"/>
<xsl:param name="first_name"/>
<xsl:param name="last_name"/>
<xsl:param name="address1"/>
<xsl:param name="address2"/>
<xsl:param name="address3"/>
<xsl:param name="postcode"/>
<xsl:param name="country"/>
<xsl:param name="email"/>
<xsl:param name="home_telephone"/>
<xsl:param name="mobile_telephone"/>
<xsl:param name="date_joined"/>
Could I call and update the javabean from the within the transform:
<map:transform src="style/main.xsl">
instatiate javabean
javabean.user_id = <map:transform src="style/main.xsl">
</map:transform>
Or would it be better to do it from within the Action and then just
call the call javabean from within the xsl page itself? ultimately I
want to be able to call the javebean parameters into my xsl or xsp
pages. What is the best way to go about doing this? Is there any
example code out there I can have a look at?

Andrew,
The authentication framework that I mentioned in response to your other post
can store any arbitrary XML data associated with the user in the session.
Since it is stored as XML, it becomes really easy to use that information
within the Cocoon pipeline.
For example, I believe you could use an aggregator to aggregate your static
content (main.xml) with the user information XML. Then use XSLT to transform
it however you want, without having to pass all those parameters around all
over the place. This seems much more flexible and extensible to me than the
approach you are taking.
