Stand alone Cocoon

Rate this Message:
Hi All,
I am new to Cocoon. We are planning to use Cocoon for report generation (XML + excel template passed through Cocoon = Excel file with values filled in). I am able to generate the report when I deploy the cocoon as a web app. Now the issue is, I want to integrate cocoon into my existing webapp. By integrating I mean, I should use the web.xml of my current web application and not the one from cocoon. i.e. every request should go through my old web.xml. and when I say generate report, it should invoke methods from Cocoon and generate reports. For ex. I want to have a method like : public Object generateReport(String xlsPath, String excelTemplatePath) and this method should invoke classes from Cocoon, generate report and return the report. Please let me if this is possible. Also please direct me to some documents, links on this. thank you in advance. Regards, Kumar.D |

Actually it was one of the goals when designing the new version. And there are people who did exactly what you described above (having a web application and using Cocoon inside it, just like you would use a templating engine or an O/R-Mapper) However there's a catch: It is still an alpha version. So the basic question is: can you live with an alpha version? If the answer is NO, then Cocoon 3.0 is not what you want - you might as well stop reading this now (I think it will be months before this goes into any king of beta phase). If the answer is YES, then Cocoon 3.0 can probably solve a lot of your problems rather easily. The basic principles are the same as those of Cocoon 2.x and it's rather easy to create new pipeline components or modify behaviour the way you want/need. ("Our" students from the TU Vienna do it all the time, even if it's not part of their project - apparently they think it's fun) Cocoon 3.0 provides an API to create pipelines programmatically and use them basically everywhere you have Java available. You can even use the sitemap on top of that if you want to and still use Coccon inside your own application like any other non-web framework. The system is already used in some commercial applications and AFAIK, Apache Sling is looking at integrating it too. (Again it's the pipeline API that makes certain things possible and interesting). We are continuously working on it, although this may not be very visible or prominent at times. Documentation is another weak point right now. So there isn't much to point you to. The general idea about Cocoon 3.0 is sketched out here: http://cocoon.apache.org/3.0/ and a (slightly) more detailed overview is ready here http://cocoon.apache.org/3.0/features.html. The documentation is for version 3.0.0-alpha-1. The current trunk contains a lot of changes and extensions and thanks to the feedback we got, this version is more consistent, easier to use, and more reliable. IMO a new release should follow rather shortly (1 - 2 months) but maybe I'm a bit optimistic on that. I am not sure whether this is possible at all with Cocoon 2.x. I guess some of the "older" guys have to answer that. I hope this makes sense to you.

It's like a one-stop-shop for the most common XSLT things you can come across. This class is also a nice example for the Pipeline API itself and how to use it for building your own ready-to-use transformations. http://svn.apache.org/repos/asf/cocoon/cocoon3/trunk/cocoon-sax/src/main/java/org/apache/cocoon/sax/util/TransformationUtils.java (However, keep in mind that this is trunk, so it has all the nice generics, packaging, etc.) > Please let me if this is possible.

I haven't looked at version 3.0 but I have done just what you describe using 2.1x and the CLI technique. Have you looked at the process for packaging Coccon as an offline application. There is some recent comment on the mailing list about it and thre is plenty of material on the web. Enjoy - it is very impressive when you get it working :)

Could you just use your working cocoon application as a web-service?
e.g. Use commons http to call it? Nice scalability implications... Ellis. On 26 Jun 2009, at 09:38, Steven Dolg <steven.dolg@...> wrote: > zzkumar schrieb: >> Hi All, > Hi, > >> I am new to Cocoon.
