Query the database from my flowscript? I have an object oriented database
(db4o.com).. is it also possible to query this database in flowscript? do
you know where to find information about this.. and how can I f.i. do this
in flowscript: "import com.db4o.*"
Can someone tell me how to do this in flowscript?
Okay, here are a couple possibilities:
1) Query the database from your flowscript. You've got the full power
of JDBC available to you; you can either write the query code directly
in your flowscript or write a Java class that does the query and gets
called by your flowscript.
2) If you really want to use a pipeline to do the query (e.g. XSP or
SQLTransformer), you can have your flowscript call that pipeline and get
the result as a DOM tree, and then grab the values out of it using the
DOM API...
var pipelineUtil = new
Packages.org.apache.cocoon.components.flow.util.PipelineUtil();
var dom = pipelineUtil.processToDOM("query-pipeline", {});
var elements = dom.getElementsByTagName("...");
var targetArray = [];
for(var i=0; i<elements.getLength(); i++) {
targetArray.push(elements.item(i).getFirstChild().getNodeValue());
}
(or something like that.)
