html:form help!!
Hi there. I just found some 'interesting' behaviour with the html:form tag that I hope somebody can explain. I have the action servlet mapped in my web.xml to *.do, this worked fine for me until I wanted some files to be downloaded with the extension .csv, so I added another servlet-mapping of action to the *.csv extension. Now however my old html:forms are appearing with the *.csv extension and nothing works (except for the csv file download - which works a treat)! Is it possible to have multiple mappings like this or does Struts just assume one mapping for actions? So, e.g. in my jsp html:form action=/secure/ladida.do but what now comes out in the browser is html:form action=/secure/ladida.csv Any ideas appreciated Luke -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
RE: options tag internationalization
Laurent I came across this very issue yesterday, this is how I solved it (probably straying too much from design into implementation): I couldn't find a way to easily (or quickly) access the internals of the messages class so I created my own. Each varying option set (e.g. coutries, states, person titles etc.) is mapped to a normal resource bundle file, e.g. countries_en_GB.properties etc. I use an application Session listener to insert into each new session a dynamic proxy that that implements a collection interface for each internationalised collection. On each request for the data by a page (i.e. html:options) the dynamic proxy queries the session for the current struts locale and retrieves the appropriate list and passes on the call to the appropriate bundle. Obviously caching and the like goes on so I'm not reloading files all the time, but the net effect is that if the user changes the locale of their session the list boxes also change. Hope that helps. Not really a design pattern though ;-) Luke PS I'm relatively new to struts - so will follow with interest to see if there is a more strutsy way of doing this. -Original Message- From: Tettoni, Laurent [mailto:[EMAIL PROTECTED]] Sent: 07 January 2002 17:15 To: '[EMAIL PROTECTED]' Subject: options tag internationalization Hi, Could anybody advise a DESIGN PATTERN for implementing internationalized struts-form:options (when using a Collection) that would use internally struts-bean:message (or similar) mechanism ? Use case: - draw content for a combo box (names and values) from a database = options names here expressed as generic, language independent keys - encapsulate in a Collection of dedicated objects - use struts-form:options with the specified collection = this would fetch localized value in the application's properties = and display combo box with localized content I could not find this functionality.

RE: Strategy for International/XML Project
Robert, For issues concerning schema languages etc have a look at http://www.xml.com/pub/a/2001/12/12/schemacompare.html I definitely recommend Log4J over servletcontext log. You may want to consider using DOM4J instead of JDOM - similar capabilities but dom4j has programmatic XPath support. Also for XML handling look at the the Jakarta xtags taglib (it uses dom4j under the hood).

I found the new commons-beanutils package that has new methods in PropertyUtils (getMappedProperty() and setmappedProperty()). To solve my second problem I now hardcoded my form bean's name into the custom tag implementation to look it up in pageContext. However, my struts release (version 1.0) doesn't populate the form bean when I submit the form. I the servlet log I do see that Struts looks up and recycles the form bean and it logs that it populates the form bean but the dynamic properties' setter method isn't called.

RE: Session Timeout question
Also if you are using a Servlet2.3/JSP 1.2 container (e.g. tomcat 4) (not sure about earlier versions) you can register listener(s) that will listen for all the session timeouts in the system or write an object into the session that implements HttpSessionAttributeListener which will be notified when it is unbound (e.g. when the session object is about to be destroyed) Luke -Original Message- From: Sean Owen [mailto:[EMAIL PROTECTED]] Sent: 03 January 2002 14:57 To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: Re: Session Timeout question A new session is created before your JSP is serviced, so I think that's why you're always getting a session object there. session.isNew() is an indirect but pretty good way of knowing when a session has just been created, and thus could be because the old session timed out. You can also put some kind of token into the session and look for that; if it's not there then you know it's a new sesssion and the old one must have timed out.

Values in to attribute values for XML JSP Docs?
Hi all. I am using the XML form of JSP (1.2) and wish to write the equivalent of the following. jsp:scriptlet int myvar = 1; /jsp:scriptlet input type=hidden value=%= myvar %/ However this doesn't work as the %= myvar % is only evaluated as an expression when being passed to custom tags. So for example the following is ok: html:hidden value=%= myvar %/ .. but I've tried everything I can think of (short of using println statements!) to output the value of any type of variable (not just scripting ones) to normal output tag attributes - but nothing works. NOTE: I cannot use %= myvar % or jsp:expression myvar /jsp:expression as these are not well formed XML and so the page will not compile. Help! I don't know if I am missing something obvious or if this is just not possible!

RE: Using Struts with XSLT
Hi Jan I'm relatively new to struts - but have come from a background of using XSLT with Servlet2.3 filters. Have to say this worked great, although as people have pointed out there is a performance hit. But I found with optimization I could reduce this to a nearly negligible amount (I also used SAXON - which is great and has improved quite a bit in recent releases performance wise.) I have a working site using XSLT, but it was written and maintained purely by me - so it was a nightmare for other people to support - as all the presentation stuff was in the XSL, i.e. raw XML data (from app server) driving XSLT sheets with embedded HTML/WML etc. This lead me to want to split out the data some more and have 2 XML streams - one describing the data and one describing the presentation (sounding familiar yet?) which I implemented myself using XSLT URIResolvers. Around this time I also discovered Cocoon and spent an interesting, but ultimately unfruitful, time evaluating and porting to it. It has a lot of nice features (many of which I'd already implemented for myself previously - annoyingly :), but I realized that what I was ultimately doing with my dual XML data flows was effectively implementing custom tags using XSLT. (Also see Cocoons XSP templating language) E.g. In your presentation XML you write something like sidebar entryusername//entry /sidebar And in your XSLT you have something like: xsl:template match=sidebar table !-- Write your entries here sort of thing -- /table /xsl:template You also find your self wanting to substitute data values for elements which may come from secondary XML streams or you may want to read values directly from Java classes. This becomes a lot more cumbersome. XSLT - Java bindings are non standard and mostly awkward to use. Then I (re-)found JSP and Struts. Taglibs have come a long way since I last looked at JSPs about 2 years ago and I realized I had the solution to my problem. Use JSP to generate the presentation layer (as it was meant to do) and use the taglibs provided by struts and Jakarta. The presentation is still separated out, using Java to access data is much simplified, and I can still bring in my XML data using the xtags library. Currently I am not planning on using XSLT at all for the moment (which makes me sad as I love it). Although I am considering that it may be useful in i18n, as I don't like all the properties files you get from the taglib. And it may be useful in defining on the fly look and feels by restructuring your XHTML etc. I'm still not ultimately convinced JSP/Struts is the 'best' way - and in general I liked cocoon. But now there are so many useful tag libraries (including support for XSLT) why go re-invent them yourself in XSLT? Plus ultimately when it comes to getting someone to support my pages when I want to move on to the next new thing ;-) I know I'm going to find it easier to find someone to support a JSP/Struts solution than my own bespoke XSLT one! Hope some of those ramblings were useful. Luke -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Setting content attributes
How do you set the values from scripting variables or the results of tag library elements of attributes for output html tags when you are using XML version of JSP? E.g. link rel=StyleSheet href=%= request.getContext %/stylesheet.css/ Simply puts the above string directly in the output (unsurprisingly - I was getting desperate trying that). If I try to use jsp:expression instead the page doesn't compile as the resulting fragment is not valid XML. Apologies for the basic question - this is driving me nuts!! Any pointers appreciated.
