request parameters and processPipelineTo?
Hello list,
I'm trying to write the output of a pipeline to a fiel from a flowscript
using "processPipelineTo".
It fails because I cant figure out a way to send request parameters to
the pipeline.
the pipeline looks like this:
<map:match pattern="parseimdbtitle">
<map:generate type="html"
src="http://www.imdb.com/title/{request-param:imdbtitle}" />
<map:transform src="stylesheets/parseimdbtitle.xsl"/>
<map:serialize type="xml"/>
</map:match>
Heres one flowscript fragment that doesnt work:
cocoon.processPipelineTo("parseimdbtitle?imdbtitle="+bizdata.imdbtitle,bizdata,out);
I get:
No pipeline matched request: famelib/parseimdbtitle?imdbtitle=tt0276751/
If I dont build the query parameter string like this:
cocoon.processPipelineTo("parseimdbtitle",bizdata,out);
and bizdata contains the wanted request parameter, it doesnt work
either, because
the parameter map is not sent as a request parameter.
So I guess my basic question is: how do I make a pipeline that can take
both request parameters and
"bizdata" parameters at the same time? Or is it the other way around?
Should the pipeline
be made to accept "bizdata" parameters only?

database issuses - (cocoon + mysql)
Posted by beyaRecords - The home Urban music <uz...@beya-records.com>.
Hi,
I am having an issue connecting to a MySQL database. Basically, any
esql tags with data between them is being written to the screen instead
of being processed and no connection to the database is being made. For
example instead of <esql:pool>mysql</esql:pool> being processed,
'mysql' is being printed to the screen. What am i not doing correctly?
The process I followed to try and ensure database connectivity was
this:
1. Copy JDBC driver for MySQL into CATALINA_HOME/common/lib
2. Define a MySQL datasource:
<datasources>
<jdbc logger="core.datasources.mysql" name="mysql">
<pool-controller max="10" min="5"/>
<auto-commit>false</auto-commit>
<dburl>jdbc:mysql://localhost/test</dburl>
<user>user</user>
<password>password</password>
</jdbc>
</datasources>
3. edit CATALINA_HOME/webapps/cocoon/web-inf/web.xml
<init-param>
<param-name>load-class</param-name>
<param-value>
<!-- MySQL -->
org.gjt.mm.mysql.Driver
<!-- PostgreSQL -->
org.postgresql.Driver
</param-value>
</init-param>

Hi Luca,
i had the same problem on cocoon 2.1.1 passing parameters with
processPipelineTo in flow.
if you have still that problem
try this:
in flow:
out=new java.io.FileOutputStream("/tmp/out.xml");
cocoon.processPipelineTo("parseimdbtitle/tt0338466", null,out)
in the sitemap:
<map:match pattern="parseimdbtitletst/*">
<map:generate type="html" src="http://www.imdb.com/title/{1}" />
<map:serialize type="xml"/>
</map:match>
Best regards
Gianluca

Cocoon 2.1.2, JDK 1.4.1_01 on Windows 2000. Anyway, I've checked it
again and still doesn't work

BTW, I've completely overlooked the reception of parameters in your
sitemap (my bad :( ): you cannot, AFAIK, use them as request parameters,
since they're Javascript objects.
Instead, you should use the jpath logicsheet or JXTransformer or
JXTemplate to use them. I'am afraid you have to change the logic of your
application considerably.

Luca,
I tried pasting in your test pipeline in my sitemap, and it returns the
xml version of the imdb page as expected.
<map:match pattern="parseimdbtitletst">
<map:generate type="html"
src="http://www.imdb.com/title/tt0338466" />
<map:serialize type="xml"/>
</map:match>
So we are not having the exact same behaviour.
Some questions for you:
1) Which version of cocoon are you running? I'm running 2.1.3 on sun
linux jdk 1.4.2_02
2) When you send parameters to a pipeline from flowscript, do you use
{request-param:imdbtitle} to receive them?

I beg to differ, I tried:
<map:match pattern="parseimdbtitle">
<map:generate type="html"
src="http://www.imdb.com/title/tt0338466" />
<map:serialize type="xml"/>
</map:match>
getting the same "Resource not found" error: smells like a HTMLGenerator
issue to me.

Luca,
This seems brilliant, but in my case it doesnt work. What am I doing wrong?
My pipeline:
<map:match pattern="parseimdbtitle">
<map:generate type="html"
src="http://www.imdb.com/title/{request-param:imdbtitle}"
/><!-- doesnt need url encoding because imdbtitle always one word -->
<map:transform src="stylesheets/parseimdbtitle.xsl"/>
<map:serialize type="xml"/>
</map:match>
Flow fragment:
out=new java.io.FileOutputStream("/tmp/out.xml");
cocoon.processPipelineTo("parseimdbtitle",
{"imdbtitle":"tt0338466"} ,out)
Error:
Could not get resource http://www.imdb.com/title/
To me it seems to indicate that {request-param:imdb} is empty when the
pipeline is called.

Well, let's put it this way: if I had to send two parameters ("x" and
"y") to pipeline "foo.xml", I'd do the following ("os" being the
pipeline's output and "x" and "y2 the Javascript variables holding
request parameters' values):
cocoon.processPipelineTo('foo.xml', {'x' : x, 'y' : y}, os);
