Two ESQL Questions
I have a couple of ESQL questions: 1) If an ESQL query throws a database exception, is there any way to log the stack trace to a file? 2) If an ESQL query throws a database exception, is there any way to handle this using the map:handle-errors section of the sitemap, so that all exceptions thrown, whether during pipeline processing or application exceptions, are displayed in the same manner?

Displaying 'progress' screen for long running reports
Hi I have a Cocoon application that provides a front-end to a reporting system, and some of the reports take quite a while to run - in the order of 5-10 minutes. I need to provide a feature whereby the user submits the report request and a screen appears that polls the report every 10 seconds or so to determine if the reporting file has been created. When it has, it will be displayed, otherwise the screen will keep displaying a helpful message to the user. Any ideas on how to do this using Cocoon? The workflow is something like this: 1) User clicks 'Run Report' 2) Request is submitted to reporting system and a helpful 'progress' screen is returned to the user 3) The progress screen checks for the report by submitting a URL. If a 404 is returned, continue to display the 'progress' screen, otherwise display the report. Regards Michael -- This e-mail may contain confidential and/or privileged information.

Why would it be a bad design, Chris? My understanding of ESQL is that it exists specifically for the purpose of extracting data from a database and formatting it as XML. What benefit is there to having a SELECT in an action, besides having people such as yourself consider it a good design.

Cocoon Connection Pooling and Database Shutdown
Could anyone shed some light on what happens to the Cocoon connection pool when the database it depends on is shutdown and then restarted. I expect an exception to be thrown as the connections are invalid, and though I don't explicitly catch it using esql:error-results in my XSP page, I expect that this exception should appear somewhere; perhaps in a log file or returned as part of the XML generated by the XSP. However, if my database has been shutdown and then restarted, the XSP below returns tradingbookSorry, no trading book results!/tradingbook. I have to restart Tomcat to get it working again. tradingbook esql:connection esql:poolmosaic/esql:pool esql:execute-query esql:querySELECT distinct vm_tradingbook_id as tradingbook_code, tradingbookname FROM V_TRADINGBOOK_VM order by 2/esql:query esql:results esql:row-results tradingbookcodeesql:get-string column=tradingbook_code//tradingbookcode tradingbookesql:get-string column=tradingbookname//tradingbook /esql:row-results /esql:results esql:no-results tradingbookSorry, no trading book results!/tradingbook /esql:no-results /esql:execute-query /esql:connection /tradingbook Regards Michael --- Michael Edge Global Markets Technology Institutional Client Group Phone: +44 (0) 20 7545 3204 Fax : +44 (0) 20 7545 1559 Internet email:[EMAIL PROTECTED] -- This e-mail may contain confidential and/or privileged information.

XSP Redirect in Cocoon 2
Hi All It seems to me that the following code will not work in Cocoon 2. I believe it works in Cocoon 1, but for some reason the request and response objects available within XSP for Cocoon 2 are not HttpServletRequest and HttpServletResponse objects, but rather some cocoon equivalents, org.apache.cocoon.environment.Response and org.apache.cocoon.environment.Request. Unfortunately these new classes do not include the sendRedirect method. Any ideas how I would do this? I need to construct a URL in my code and redirect to that URL. xsp:logic String url = URLEncoder.encode(url + whatever + parameters); response.sendRedirect(url); /xsp:logic Thanks Michael -- This e-mail may contain confidential and/or privileged information.

XSP Best Practise Question
Hi All I have a question regarding the use and purpose of XSP. I believe that XSP is an attempt to separate content/logic from presentation, and I believe it's possible to use it in this way. However, in many of the samples (such as results-dept.xsp below, found in the tutorial) XSP is used to retrieve XML from a database and wrap it in some sort of pseudo-html, which is then processed by a logicsheet to produce proper HTML. To me this defeats the whole purpose of XSP. The XSP below mixes content and presentation, and if it contained xsp:logic sections it would be even worse, mixing content, logic and presentation. My thoughts are that, as the XSP is a generator it should generate XML in some suitable form. If logic is needed within the XSP dynamic tags can be used and translated using a logicsheet (or made part of XSP if they are not resuable). However, the actual presentation of this XML should be left to a stylesheet. I would really appreciate your comments and thoughts on this as we are trying to implement multiple projects here using Cocoon and want to use a consistent, best-practise approach.

Merging Dynamic Content and Static HTML in Same Page

For example, I would like to produce reports that all contain a standard header with images and toolbars, etc., but where the dynamic part of the page is generated by an XSP using ESQL.

My understanding is that aggregation creates a single XML fragment from many sources, concatenating them all together. Then it applies the transformation and serialization. However, my documents are not XML but HTML. Using aggregation and include it seems as though these documents will be converted to XML, merged into one large XML fragment before being transformed via my stylesheet. I don't want or need the stylesheet to process the HTML at all. I sort of need the aggregation to happen after the transformation rather than before. Any suggestions? Or are there other ways to accomplish this? Surely this must be quite a common requirement?
