Re: background task management
Hi David, I am interested in your background task manager. I downloaded your document and your code from Bugzilla and found that several source files are missing. e.g. the Actions described in the document and com.dotech.cocoon.environment.thread.BackgroundThreadEnvironment used by the FileUploadTask. I'm specially interested in calling a cocoon pipeline from a background thread. Am I right that the BackgroundThreadEnvironment is responsible for that? Maybe you can upload the missing source files to bugzilla. Regards, Peter BTW: I would not recommend to use Microsoft Word files for documentation in an open source project. Especially if it's not bound to the Microsoft Windows platform. Better you use plain text, html or xml for contributing documentation.

Re: background task management
Hi David, there are still missing the sources for com.dotech.cocoon.environment.thread.BackgroundThreadEnvironment and com.dotech.messaging.Message to compile all classes. The latter one is less interesting, but the BackgroundThreadEnvironment seems to be pretty cocoon specific ;-) I would suggest you to create a complete source package with sitemap.xmap and cocoon.xconf snippets (already in user documentation) which can be easily compiled and testet. I think this will raise the changes that a commiter will review and commit the code. Do I unterstand correct that the BackgroundThreadEnvironment is some kind of FakeEnvironment (no output/no input)? I digged a bit around in your code and in the cocoon core and environment code and now I am a bit confused about using different Environments with the same Cocoon instance. What I was wondering about is that you use the HTTPEnvironment to resolve (and construct) a Source object (in UploadTaskAction) and later use your own BackgroundThreadEnvironment (in FileUploadTask) to process the source. Does this work without problems? What I want to do is generating PDF files in a background thread triggered by a HTTP request. I guess I have to use the FileSavingEnvironment to do this. I am somehow curious how to correctly use Cocoon and the CocoonComponentManager to do this. Can you give me some hints or point to some docs about this? Is this the following code the right approach? env = new FileSavingEnvironment(...); Processor processor = (Processor)this.componentManager.lookup(Processor.ROLE); processor.process(environment); Thank You, Peter David Kavanagh [EMAIL PROTECTED] wrote: Peter, Thanks for finding the omission. I've uploaded a zip including the two actions. Yes, that environment object was needed to keep the underlying code happy. I don't do anything with the pipeline results. I just scan for error elements because I was doing some SQL commands via the SQLTransformer. If I can be of any further help, please let me know.
