RE: Logicsheet transformation happening but XSP not running

Mon, 23 May 2005 13:23:34 -0700

Title: Message
java.exe can be started with the options -server or -client.  Client mode (default if neither option is specified) is supposed to startup faster while server mode is doing more aggresive and time consuming hotspot compilation for better long-term speed.  However, on Sun Solaris I could never see any significant difference in speed for Cocoon requests.
 
Your description sounds more like a buffer flushing problem.  Do you have any more indications of the failure rate or whether it could be a multi-threading problem?
 
Cheers, Alfred.

many thanks for your feedback. I don't think it is a manifestation of that bug you mentioned. I've done some comparisons of the two .java files, one created from the xsp page when it does run and the other when it doesn't and there are just bits missing eg
    import org.apache.avalon.excalibur.datasource.DataSourceComponent;
is missing in the non-working version along with a lot of other things.
 
Thanks also for that suggestion with the jvm but I'm afraid I don't know how to run it in client mode... can you shed any light on this? What are the implications of doing it?
 
Kind Regards,
 
Phil

Could be a manifestation of http://issues.apache.org/bugzilla/show_bug.cgi?id=32934.

Otherwise try to run your JVM in "client" mode.  (We had a similar weirdo behaviour with an earlier JDK1.4 version in "server" mode.  Since then we are using "client" mode also in production.)

HTH, Alfred.

Subject: Logicsheet transformation happening but XSP not running

Hi,
 
Problem: use of internal pipeline transforms xsp logicsheets but the resulting xsp doesn't run: just gets spat out as xml.
 
I have been using Cocoon for a number of years but only really as a development engine used for aggregation and xml transformations for static sites. Over the last few months I have been developing a fully fledged e-commerce application with it and when it works I have found it to be excellent... Most problems despite my cursing have turned out to be of my own making but this one I just cannot work out.
 
In brief I have a site which consists of many files each for a different purpose (eg productlist.xsp, orderedit.xsp) but they all share another xsp file called menu.xsp which contains the menu structure. This is obviously to avoid duplicating it. Menu.xsp must be an xsp because it shows links (eg View Order) based on whether a session orderid is null or not. When one of the 'public' files is called eg productlist.xsp the generator calls an internal pipeline which performs the include so that the whole can then be treated as serverpages and the xsp compiled and run.
 
Now that all works fine and dandy in pages that don't contain Logicsheets. BUT sometimes when a call is made to a page with a logicsheet in it the resulting page will just contain the result of the logicsheet transformation rather than what I would expect ie the result of having run what would be the resulting xsp. The annoying thing is that this only occurs sometimes, and should I restart Tomcat (having deleted the work dir) everything is fine and its as if Cocoon looks around innocently and says "what, ME not compile the xsp... no NEVER!?!" then if I continue making requests, at some point in time it will do the same. This happens if I make the same request over and over again so it is not a change in other variables. One thing I should point out is that I am using logic sheets within logicsheets eg my custom logicsheet also uses the esql logicsheet.
 
There are no errors in the sitemap unless the processing of the document requires some bit of xsp which hasn't been run eg where I have used Java code directly eg
intOrderID = new Integer(<esql:get-int column="intOrderIDOut" from-call="yes"/>);
 
What I cannot understand about this behaviour is that it happens so inconsistently: there it is happily serving the same page and then all of a sudden it will just fall flat on its face. Could it be related to available resources?
 
Cocoon 2.1.7
Windows XP
Java j2sdk1.4.2_07
Tomcat 5.5
 
Any help or suggestions would be gratefully appreciated
 
Thanks in advance
 
P. Coultard
