Hello all,
I have a queston on calling Java from flowscripts. In my project, we have most of the businesslogic running on a weblogic server, implemented as stateless sessionbeans. I call these beans from a simple "client" class, which I instantiate in my flowscripts.
Currently, in every flowscript function that needs access to businesslogic I import and instantiate the "client" class that talks to the weblogic server.
Questions:
Is this an efficient way of doing this? Given that our webapplication is going to be under heavy load (popular national-wide telecom application), will my current approach scale well? My client class seems to be cached on successive different function calls to it, but I'm a little wary of later problems with scalability.
The "official" cocoon doc is somewhat short on info best practices in flowscript->java situations. My current impression is "you can instantiate classes, call static methods without instantiating, or wrap your code into Avalon components that may or may not give you performance benefits." :-)
Thoughts on this?
regards, Thomas Nilsson
(Example from my flowscript below- I call a function 'shortnumber' to set up a jxtemplate page with a basic form in it, and 'shortnumber_submit' gets called when the form is submitted.)
Flowscript snippet: ----------------------------
function shortnumber(){ try { //Get shortnumber from service layer
importClass(Packages.no.marcello.wo.client.test.CocoonClient);
var client = new CocoonClient();
var shortnumber = client.getShortNumber();
// Prepare language elements used in the page.
var language = {
shortnumber: "Kortnummer",
store: "Lagre",
}cocoon.sendPage("shortnumber.xml", {"shortnumber" : shortnumber, "language" : language});
} catch (e) {
var error = "Error:" +e.name +" Error message: " + e.message;
cocoon.sendPage("error.xml", {"error" : error});
}
}
function shortnumber_submit(){
try { // Get newShortnumber from form input
var newShortNumber = cocoon.request.getParameter("shortNumberInput");// Update shortnumber importClass(Packages.no.marcello.wo.client.test.CocoonClient); var client = new CocoonClient(); client.setShortNumber(newShortNumber);
// Show confirmation message in the shortnumberset webpage
cocoon.sendPage("shortnumberset.xml", {"shortnumber" : newShortNumber}); } catch (e) {
var error = "Error:" +e.name +" Error message: " + e.message;
cocoon.sendPage("error.xml", {"error" : error});}
}
