Large xml's in cocoon
Hi, I have a xml file that contains database rows. If the number of rows are greater than 5000 then cocoon fails to tranform them to html and display them. It gives a blank page with no errors. Has anyone experienced this before? Is there a way I can make cocoon perform better with big xml.? Any suggestions,inputs are welcome. Thanks, Anna.
Isolation level for database
Hi, I am using cocoon's connection pool to make connections to my informix database. I think the connection cocoon is making is trying to lock rows in the database. In my application I have only reads no writes so I want cocoon to make dirty reads instead. Is there a place where I can set this? set islation to dirty read; My connection params look like this jdbc logger=core.datasources.myserver name=myserver pool-controller min=3 max=10 / auto-commitfalse/auto-commit dburljdbc:informix-sqli:// dev:1000:informixserver=myserver;Database=mydatabase/dburl userinformix/user passwordpassword/password drivercom.informix.jdbc.IfxDriver/driver /jdbc Thanks, Anna.

Re: Cocoon portal and excel
You will also want to make sure that the excel page is then generated into a new frame and not as part of the portal page. This is something I am looking for. How can we generate the excel page in a new frame. Here is the code that I used. The file is quotehistory.xsp I have a xsp page which has 2 submit buttons. input name=submit1 value=GO type=submit/ input name=submit1 value=EXCEL type=submit/ Both refer to the same href. Note: The href points to the same file. form href=cocoon:/coplets/search/quotehistory.xsp method=get In my site map here is the match for quotehistory.xsp . Check the map:select that I am using. When user clicks on GO then I want the out put to displayed on the screen. When user clicks EXCEL I want the output to be displayed in a excel file. When I click on GO its working fine, when I click on EXCEL it isnot generating a excel page it is displaying output in the same coplet but it is not tranformed well because it is not html. Also when I click on GO and the output comes to QuoteHistoryResult.xsp . in this page I placed a hyperlink that would generate excel that works. The xsl file and serializer that I am using are just the same and that works. Dont know where the problem is. map:match pattern=quotehistory.xsp map:act type=validator map:parameter name=descriptor value=context://newhistoryserver/defs/ descriptor.xml/ map:parameter name=validate-set value=securityquote/ map:generate type=serverpages src=quotehistoryresult.xsp label=raw map:parameter name=from value=quotehistory/ /map:generate map:select type=request map:parameter name=parameter-name value=submit1/ map:when test=GO map:transform src=context:/newhistoryserver/styles/ searchresult.xsl/ map:serialize/ /map:when map:otherwise map:transform src=context://newhistoryserver/styles/ page2xls.xsl/ map:serialize type=xls/ /map:otherwise /map:select /map:act map:generate src=quotehistory.xsp type=serverpages/ map:transform src=context:/newhistoryserver/styles/search.xsl/ map:transform src=context:/newhistoryserver/styles/ dynamic-page2html.xsl/ map:serialize/ /map:match Thank you for the patience.

Cocoon portal and excel
Hi, I am using cocoon as a portal server. In one of my coplets when the user submits a form I want the output to be displayed in a excel file. When I have the excel operation in a submit button this doesnt work. If I use a hyperlink in the page with all information in the url then it works. Can anyone tell me how to generate an excel file as output for a coplet. I want the excel to be generated and the coplet should remain the same. Please let me know if there any way of doing this. Thanks, Anna.
Re: InitParameters in Cocoon
I could put in a properties file but its just one property so didnt know if it does make sense. Well if I cant reach web.xml then I have no other alternate anway. Anyone else successful trying to get access to initparameters in web.xml? Thanks, Anna. On Thursday 29 April 2004 06:32 pm, Upayavira wrote: Why do you need them there. Can't you put them somewhere else? I've failed before to get hold of web.xml parameters.
InitParameters in Cocoon
Hi, I have been struggling with this problem since a week. Can someone please shed some light. I have some init-parameters defined in web.xml which are related to my application running on cocoon. When I do context.getInitParameter(paramname) in a xsp it returns null. Also in action files String limit1 = ObjectModelHelper.getContext(objectModel).getInitParameter(timelimit); when I use the above command I get limit1 as null. Am I missing something here. Thanks in advance, Anna.
Coplets and Excel Generation
OK. I posted the same question earlier but re-framed it so that someone can me suggestions. I have coplet which accepts some input keys and shoud generate a excel file. When I click on submit it takes to the ill formatted html file but does not generate a excel file. I use the same pipeline(generator,transfomer and serializer) outside a coplet like in a hyperlink. It works just fine. Can someone tell me where I am making a mistake. Is there anything we have to specify for a coplet to generate a xml file. my pipeline looks like this map:generate src=context://historyserver/coplets/search/sec.xml/ map:transform src=context://historyserver/styles/page2xls.xsl/ map:serialize type=xls/ Any help is greatly appreciated. Thanks, Anna.
Features of cocoon
Hi, I was asked to look for portal servers in the industry . I found cocoon has a interesting mix of XML and the portal features. Can someone please confirm if the following features are available with cocoon. single sign on Search feature( I guess it has lucene integerated) XML data tranformable into different formats(like HTML,WML,PDF) etc security(role base management and authentication) Ablility to easily add new pages to the portlet Personalization depending on users requirement for look and feel Ability to quickly plug in new features. Any help is very appreciated for me to decide if cocoon is the right one for us. Thanks, Anna.
