That (String) can also happen if uploads are not turned on in web.xml - in case
these are different webapps, or on different servers.

Hi,
i try to upload some images and i use =

it's working on some js but failed on one :
this one works :
var role = 'org.apache.cocoon.components.upload.FileUploadManager';
function upload_shop_photo() {
var uploader = cocoon.getComponent(role);
var part_shop = cocoon.request.get(shop_photo);
try {

uploader.upload (part_shop);
cocoon.sendPage(success.html);
} catch (Exception) {
cocoon.sendPage(failure.html);
}
}
this one does not :
var role = 'org.apache.cocoon.components.upload.FileUploadManager';
function upload_player_photo() {
var uploader = cocoon.getComponent(role);
var part = cocoon.request.get(player_photo);
try {

the diff between upload_player and upload_shop is the name of the
function of course and the var part where the name differ.
the following error occurs :

line 8: Can't find method
org.apache.cocoon.components.upload.FileUploadManagerImpl.upload(string).
i already met this problem before and just change the var part =
cocoon.request.get(player_photo); to something like var part_shop ;
but here nothing goes better.
any ideas are welcome.

It is aready cached automagically from what I can see for each unique

what is cached by going to the /status sample page. You will probably also see
a difference in response time after the first request.

I'm not quite sure, but I have a feeling that it is caused by multipart forms and SSL used together. Well, it is only suspicion, and I can't really prove it. Ouch IE purportedly has bugs relating to POST over SSL. This was discussed extensively on the Jetty-support mailing list in February (for some reason, searching the gmane archive only turned up 3 articles, but there were a lot more). See http://support.microsoft.com/default.aspx?kbid=831167 and see if that looks like it might be related... Unfortunately, I can confirm that this does appear to be related to IE, POST, and SSL. I have quite a bit of experience observing this problem in an application totally unrelated to Cocoon. In that case, it's on Netscape Enterprise Server - not sure where the SSL support comes from if it's not native to NES. The point is, doesn't appear to be related to anything on the server. In our testing, the POST never arrives in some cases. In other cases, it appears to arrive with no POST body (i.e., it's truncated).

My blog entries are not stored in iCal. Nope. But in this case, you'd need to find a way to convert a list of your entries to whatever intermediate format and then take advantage of the rest of the bits of the puzzle being considered. I think there is value to a generator that simply produces a blank calendar, with dates grouped by month and week. How else would one do calendar based navigation? I think this would be possible to initiate with an empty intermediate format document in the proposed scenario. The point is one would generally want to start with a list of events (calendar entries) and decorate that with the calendar (date) data around it. If you start with the caledar, you would probably have a clumsy or inefficient time getting the event data. With made up xml in your case, cal:calendar start-date=03-01-2004 view=month /cal:calendar might result after the decoration step in what you want, something like: cal:calendar start-date=03-01-2004 view=month month name=March week number=1 leading-days month=February day name=Sunday date=29/ /leading-days day name=Monday date=1/ day name=Tuesday date=2/ ... /week ... /month /cal:calendar If you want to indicate where your blog entries actually are (by linking those dates, but not the others for example), it will be better/easier/more-resuable IHMO to start with a list of them, rather than start with the calendar and do it the other way around.

One doesn't yet exist - how would you picture it working? Geoff WARNING: I tried to compress many hours of brainstorming over two occasions into this twenty minute e-mail. Since we are all tossing ideas around anyway, I don't apologize for the disorganization of the ideas. I have some rather involved notes in one of my idea books. I envision this as a transformer, really, but then I remember a long conversation at Starbucks about the generator mindset vs. the transformer mindset with you and Jack. I think parts of this problem fit each mindset. The transformer would look for something like cal:calendar/. As seen in many PIM programs, the resulting content has many different incarnations. Conceptually, I envision this as a view of some time period, subdivided arbitrarily. A view of the current month would probably be the default output, with alternatives being multiple months, a single week or multiple weeks, or even a single day with multiple time slices being displayed. Additionally, I could see the transformer looking for content inside the element, for example [1]. (I read somewhere that footnotes in e-mail is bad for some reason.. anyone know why?) I think this is one of the cool parts of the idea... a calendar is really a representation of a set of events. Therefore the input to the transformer would be a set of events and some parameters for how to display them. So, now to think about output. Since I see this as a view component, the goal of the output is to balance a certain amount of layout information with a certain amount of display flexibility. Here's a shot at the single month output: [2]. The reason for all the layers here is that I'd like to be able to suck in an ical, an apache log file, or anything else one could think of as a set of events. I have two mid-term use cases: 1. visualization of timesheet data 2. shared calendar display (using webdav for shared versioned access to ical files I think) Well, I'd love to hear some thoughts from people who have done more with Cocoon than I... yes you Geoff :) See my response in the other part of this thread - what do you think of going xcal for step one? I'll have to comment on the below later, but I think it's the job of the transformer (step two in my other email) to fill in information related to dates, day names, etc. and the following xsl just to translate to html/whatever display. I don't want to have to figure out whether the current february has 28 or 29 days in xsl for example.

John Lianoglou wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 MAN, I have been meaning to get around to this for the longest! It seems to me that one would want to stand on the shoulders of giants; I would suggest that a Calendar Generator leverage the efforts of the IETF iCal / xCal working group. That is my instinct as well. Unfortunately, everything seems to use iCal (mozilla, outlook, apple iCal) and from what I can find xcal seems to be stuck between draft 2 (from 2002?) and draft 3 which may change things up significantly if it is ever finished. These are just conclusions from browsing the ietf-calendar and xcal-dev archives, so please correct me if anyone has a better pulse on where things are really at. (see thread at http://www.imc.org/ietf-calendar/mail-archive/msg11885.html) So, we are probably looking at 1) a generator to transform ical to some intermediate format (probably xcal?) as you note below. If someone happens to have native xcal lying around, they could then just feed it right into the next steps. By the same token, if someone has a custom non-ical format (i.e., database, exchange server, etc.) they can stick some other generator in here. 2) a transformer to take this format and decorate it with calendar data (transforming to yet another intermediate) and 3) possibly a utility stylesheet for transforming this to a pretty html format. The last one would be generally application-specific, but a well designed root stylesheet could go a long way toward simplifying that process. This will allow Cocoon to make extensive use of published iCalendar files from, well, obviously wherever! :) That'd be great. In fact, a sample providing a webav location for ical publishing and a few pipelines to view that data would probably be a big hit. This is admittedly an idea very informed by the circumstances that raised the idea for myself, but I imagined such a generator to read an icalender file and make a SAX stream as xcalendar format (which the working group has already fleshed out and published for us)! What works for you will probably work for others unless you have oddball requirements - so that's not a bad thing. One problem I see with the ical/xcal standard is that it's not designed to be a database - for example when selecting one week out of a calendar covering a year you may need to parse (and generate sax for) the whole thing though it would be otherwise unnessary.

Re: Eventcache - Invalidate from XSP?
Thomas Zehetbauer wrote: Is it possible invalidate cache entries from an XSP page? Yes, but I'm not sure it should be encouraged According to the samples one can either use flowscript (event.js) or the CacheEventAction to invalidate entries. I would however prefer to raise the necessary events directly from a XSP page, but while there is an implicit cocoon object in flowscript that enables one to get access the event-aware pipeline implementation I could not figure out how to implement cocoon.getComponent() in XSP. Hopefully you meant an XSP action. XSP Generators and XSP actions both inherit a reference to the ComponentManager/ServiceManager which you can use to look up the Cache just as the CacheEventAction does. One could also override the inherited compose() method and several other lifecycle methods which would make this feasible. A generator is IMILHO (in my increasingly less humble opinion :) ) just plain the wrong place to do this. If you are using actions, though you should seriously consider using nested actions to do this: map:act type=updateYourDatabase map:act type=uncacheEvent map: !-- rest of your pipeline if successful -- and so on. In this case, I'm not sure why you wouldn't just use the existing CacheEventAction. If you need to modify its behavior, it really should be trivial to do in a subclass. If not, explain why and it can probably be fixed. To make myself more clear, I have a database which is queried from an XSP with the output being cached in an event-aware pipeline. Another XSP page modifies this database and wants to expire the affected cache entries. Is this possible? How? So, yes - possible but maybe not necessary. However, depending on the database you're using I'd seriously look at the option to fire these events directly from a db trigger on update of your database. This way you are free to have any other process manipulate the database and not have to worry about invalid cache. In real life, I have often had to resort to direct database manipulation and the confidence that all necessary events are fired right from there automatically is a great help. Not all DBs will support this (I think Mysql does not yet) but worth taking a look. Geoff - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

What I have and like is the ability to call update.html?databases=a,b or update.txt?databases=a,b and accordingly invalidate pages depending on these. I guess using actions for would make it far more difficult or even impossible to generate this output. ?? Don't see why this is difficult with or without actions. Have you looked over the modular db actions samples, for example? I wonder how it is possible to get a reference to cocoons event-aware cache implementation from an database trigger, do you have any working example for this? No, no. You wouldn't use a direct reference to Cocoon's cache from there - you'd either fire off a jms message (see the jms block for examples) or you'd use http to call a pipeline which executes the action. JMS is the way to go hands down if you ever need to load balance across several Cocoon front-ends. I'm being terse just because I don't have a lot of time ATM. Feel free to keep asking questions.

Re: ESQL update and select statements in the same map:match problem
It's not a bug -- and I wouldn't recommend using a workaround like the
one below (which would probably work). Don't try to modify the data
model while it's being turned into sax (the job of the generator).
Other non-MVC friendly frameworks force this but Cocoon almost forces
you not to because of all the problems it can cause in real-world
applications.
In your case, either use flow to call logic which modifies your database
(beyond scope of my response) or use an action. Actions and flow are
both guaranteed to execute before the pipeline is assembled and are
designed to be the place for data manipulation (with the exception of
the side-effect transformers like the SQLTransformer, also out of
scope). If you already have an xsp which does the job, turn it into an
xsp action and you're done.

I don't know anything about the internal workings of the map:aggregate, but
I would guess it is not waiting for the first part to complete before
opening a connection for the second part. This would make sense, for
performance reasons, and there is no particular reason for cocoon to expect
the parts to be dependent on each other. So I don't think it is
necessarily a bug, nor a caching mechanism, just that map:aggregate doesn't
imply sequential processing.
Just curious, should the map:aggregate have an element attribute
specifying the root element for the combined output? Also, what does
strip-root='yes' do? I couldn't find it in the documentation
(http://cocoon.apache.org/2.1/userdocs/concepts/sitemap.html#Aggregating).
You could probably make things sequential (and still achieve aggregation)
by using either a cinclude transformer, or even more simply by using an
XSLT transform step with the document() function, e.g.,
...
xsl:template match=output-of-update-point
new-root
xsl:copy-of select=./
xsl:copy-of select=document('cocoon:/xml/exec.get_point')/
/new-root
/xsl:template
...
with a sitemap like
map:generate src=cocoon:/xml/exec.update_point/
map:transform src=aggregate-get-point.xsl/
or some such.

/map:aggregate
where i call 2 .xsp
1. update_point.xsp
where i update a record in my database
2. get_point.xsp
where i get the updated record
the problem is that this aggregation update the database record (i have

is this a caching mechanism case, is it possible to bypass this problem or

forgot to attach the the svg file, here it is
I just looked quickly at your xsp and before we get any further into
this, can you explain why you're not using an image/database reader for
this? Is it because of the hibernate support? I don't see any purpose
for putting this into svg (as base64 jpeg) just to re-serialize as jpg.
I've seen about a million messages go by about this general topic so you
may just need to quickly summarize the issue.
Assuming you have some need to do it this way though, I'd recommend
putting some logging (or just System.out.println which should get spit
out in your terminal console) to see what is going on internally. Are
you sure you're getting data back in each case fo example?

Hi,
I have constructed a pipe which handles image requests and spits
out an svg. On the page in question there are 3 images. The pipe is:
map:match pattern=unframe/*/*.jpg
map:generate type=serverpages src=xsp/svg.xsp
map:parameter name=imageNum value={2}/
map:parameter name=artistID value={3}/
/map:generate
map:serialize type=svg2jpeg/
/map:match
The image link is built up in my xsp page as:
artists-photo1
xsp:element name=img
xsp:attribute
name=srcartistImage/1/xsp:exprartistID/xsp:expr.jpg/xsp:attribute
/xsp:element
/artists-photo1
So I have 3 images on one page which are built up in that format.
What is happening is that the first image call is made no problem,
and the image is displayed on the page. The second image is now
requested but the image is never loaded and the browser just sits
there waiting for an image to load. What is causing this, and what
can I do to resolve it? My svg page is attached. The html format
of the calling xsl page is:
. snippet .
tr
td valign=top align=centerxsl:apply-templates
select=//artists-photo1//td
/tr
tr
td valign=topxsl:apply-templates
select=//artists-photo2//td
/tr
/table
/body
/html
/xsl:template
xsl:template match=artists-photo1
xsl:apply-templates/
/xsl:template
xsl:template match=artists-photo2
xsl:apply-templates/
/xsl:template
many thanks in advance

Hi Simon,
I think I am coming closer to the answer I have been
having with the svg canvas size not changing. If I make a
request for the image outside of the iframe it is loaded
into,
(http://www.mysite.com/cocoon/beyarecords/artistImage/1/4
6.jpg), then the image changes according to the sizes I
give it. If i try and call the image so that it loads
within the iframe, then no matter what values you give the
height and width of the svg tag no change to the canvas
size takes place. Any ideas?
Hi Andrew,
maybe you have inside your html-source image width=
height= -statements, then the browser scale the image
allways to this size. If the image is larger or smaller, the
browser scale ever to this size. If so, remove the width=
and height= and have allready img src= / and the
browser will diplay the size from your image.
Best Regards,
Simon

Re: upload dir cleared at Cocoon startup

To be able to do multi part uploads I went to web.xml and set the enable-uploads init-param to true and the upload-directory to data (no quotes of course). As I need ony one upload directory, it looked like the obvious choice to me to have Cocoon handle the uploads. Since I set these parameters, my upload directory is cleared totally when I restart Tomcat. This is totally unusable of course. It worked perfectly in an older version of Cocoon, but with a very recent CVS HEAD the upload dir is cleared. I have looked all over the web.xml file, but can't see any indication of this being settable. I'm not talking about uploading a file and processing it. The whole directory is cleared at Cocoon startup. Any ideas? I can't find any mention of it anywhere. Not much time now, but: 1) Make sure you've read and understood the link provided in the response from Askild. Sounds like knew that already though. 2) What was the older version of Cocoon approximately? 2.1.3? pre 2.1.0? 2.0.x? 3) Where is your upload dir, and did you switch from tomcat to jetty? 4) If you stop the container (jetty, tomcat, etc.), place a file in the upload dir, start the container, check for the file replace if missing, upload a file, check for both files replace the original if missing (the uploaded file should not be there after the request finishes), stop the container, check for the original file what happens?

Re: FileUploadsWithFlow problem
Bert Van Kets wrote: Hi all, I have finally gotten the FileUploadsWithFlow sample working without errors, but I still can't see anything arriving on the server. :-( Finally got a chance to look at this tonight, and I think I have answers. I have not tested any of this, so it's all fresh from 5 minutes in the patch code, and cvs (all while watching a very interesting show on the Medicis...). Point is, check what I'm saying - I could be wrong. I get no error anywhere. Not in the console, not in the browser, not in the logs. The Flow script throws me to the success page, which should mean the object was successfully created. I think you're right. The logs should go into core.log, but the default logging level (set in logkit.xconf, modified if desired by build properties) is WARN or ERROR now. So, to see the .debug() level as in this case, you need to modify it to lower to DEBUG. From what I read in the FileUploadManager.java file the upload directory is taken from the context. But regardless of what I set in web.xml I see nothing hapening there. I know that Cocoon removes the files from the upload directory at the end of teh request, but is this also the case here? After all the file is manually written to disk. Yes, this is a flaw of the upload manager component as written - because it uses the upload dir in web.xml as the default destination dir, the default behavior is to rename a PartOnDisk to the same file name. When the files are cleaned up at the end of the request in 2.1.3 and before all PartOnDisks in the Request are looped over and the underlying File deleted (even though you've resaved it). Ironically, because the code in 2.1.3 looks for PartOnDisk, if you set autosave to false the PartInMemorys will be skipped over during cleanup and the file would survive. To use the component as is, simply configure a different upload dir, which you can do from reading the component info by adding this somewhere as a top-level child in cocoon.xconf: upload_manager !-- from shorthand in roles file -- uploadfolder/any/other/dir/uploadfolder /upload_manager There is a new feature in current cvs, about to be released in 2.1.4 which mitigates this issue, but the component needs to be modified to take advantage of it. Three new methods are added to Part, but the important one is called setDisposeWithRequest(boolean) which you can use to signal the framework to leave this item alone. The default if you do not set it is true (erase at end as now). So, with this you no longer need a component for the simplest case: uploading all files to one directory, set in web.xml. You could in your flowscript just get the Part as described now on the wiki and call part.setDisposeWithRequest(false). C'est tout. What do I need to set in the web.xml file to get things running? Do I need to copy the file to a different directory again after the FileUploadMagager has already written it to disk? Just to make sure you understood the above, you should be able to provide several interesting answers to these questions yourself now... If I get this running I promise I'll update the Wiki page so it's more usable for newbies like me. Please do.

Re: Memory Leak with Tomcat (was Re: A notebook for Cocoon development)
Brent L Johnson wrote: None that I've noticed. But unlike John, I dont wait for OutOfMemory.. once performance drops I can't stand it so I just restart Tomcat. I thought you were saying this problem spanned restarts - obviously we're talking about re-deploys in a running container then. So how do you redeploy? Drop a new war in? Using the tomcat manager app? It does span restarts.. but the first few restarts work fine. The way *I* fix the problem is I have to completely kill tomcat, and check for any running java processes and kill them.. let the machine sit and start Tomcat back up again. It's really weird, but I never really worried about it too much. Ah. Gotcha. This sort of rings a bell - I don't suppose you have checked tomcat's bug list? If you wait long enough after shutdown without manually killing processes, do they clear up on their own? If it helps any.. the first thing that signals a problems is that the site gets very slow for no apparent reason (and Tomcat is sucking up 90% of the CPU of a 2.4Ghz Xeon processor). Then Batik stops rendering images.. I get broken images in the browser. Then, usually, the site completely stops responding. If I then just do a quick shutdown.sh (sleep 2) startup.sh.. it may or may not work.. sometimes I have to run a shutdown and wait a few minutes and start it back up (maybe 2 second sleep isnt enough time). Ah, I missed batik before. That's another possibility, especially if John is using it too. Can you check cocoon's bugzilla for issues related to batik? The standard Tomcat shutdown.sh and startup.sh commands. And that fixes the problem? So we're talking about a memory leak on reload which could either be on tomcat's end or our end, but I'm assuming this would be a well known problem if it were tomcat. It does if I shut it down manually (without my script that just does a shutdown.sh, sleep 2, startup.sh).. wait about 30 seconds then start it back up again. Or I can use my script, but I may have to run it 3-4 times before everything works correctly. I can tell it didnt work correctly if 1) batik still isnt rendering images, or 2) I get no response from the server. That may answer my earlier question? If I've got all this right, can you file a bug report in bugzilla on this? If you summarize our observations and link to these messages at marc.theaimsgroup.com that should be perfect. I have very little time to dig in personally right now, but someone will probably be able to soon. Sure - I'll see if I can reproduce it and make more detailed observations.

Re: FileUpload with Cocoon
Nicolas Toper wrote: Hi, I'm writing an XSP to manage uploading of file and I'm wondering how do you know which class is used between PartOnDisk and PartInMemory? I thought the wiki page answered this pretty clearly. PartOnDisk is used when autosave-uploads is set to true, PartInMemory when it is false. You can find out which by using instanceof, or you can use them polymorphically as objects of their common superclass, Part which exposes getInputStream(). autosave-uploads param in web.xml used to mean that uploaded files in the request were _permanently_ saved to disk. Because this behavior is either on or off for the whole application (for now) it was decided that this may become a security hole and the behavior was changed to temporarily cache the file out to disk, but to remove it at the end of the request. Actually I want to do a pretty simpel things: get the file and copy it to the user defined location... I was thinking of writing this XSP :=) Unless you're doing this in an xsp action, be aware that this is not how generators are meant to be used. Generators are the expression of your data model for a page in xml sax format. Don't use them to do things just because you can. Generally you should use flow or actions (and in some cases transformers with side effects). There is in the archive posted a file upload action which does exactly what you want to do, and plans are in the works for an easier way to do this out of the box with flow.

Okay, this seems pretty weird, or at least counter-intuitive... This is what I'm seeing. When I post the audio file to cocoon, I can see a RequestFactory.getServletRequest() occur. Then, it goes through the parsing process until it finds the file part and then appears to save the file to disk at the appropriate place. (it puts an attribute in place called 'file' whose value is the resolved path to the file it saves. Now, I'd expect that the next thing I'd see would be my custom generator that is sitting on this pipeline get the request object, but that doesn't happen. Instead, I see a second getServletRequest() call, also with multipart/form-data encoding, but a different boundary and as such I think a completely different request. (Actually I know it's a different one, because I can see the constructor call) The whole parsing routine takes place and there is no file part to this request. It is the result of this second getServletRequest that arrives at the generator, and it doesn't have the 'file' attribute. In addition, the file has been deleted, one way or another (I know it is transient - only for the life of the request, which must already have been cleaned up) Clearly something odd is going on... Any ideas? Are you using cinclude or something like it? Can you send the relevant bit of your pipeline?

It was wrapped by an action, but it reacts the same with or without the action. I tried the upload sample xsp and of course, it works as specified - so something else is going on. Next, I hacked on the file upload example to have it send to my pipeline. Here, it appears to work as expected -- the file path is in the parameters and I can access it. So, that leads me to believe that there's something unique on the client side. This piece of the application we're building uses an audio recording applet to record student responses to activities, then sends the audio file to the server where it is stored. The applet is something of a blackbox from freedom audio.

I like the suggestion that Session implements HttpSession - that looks
like a fairly trivial change and is likely to support any framework that
requires one.
No, this proposal has been vetoed (and discussed before and vetoed then

Any suggestions. This is currently a show-stopper so I need an answer -

it was left in for compatibility and is screwing you up. The fact that
you have it in implies that you are basing your understanding off a mix
of 2.0 and 2.1 documents. Make sure you read the note at the top of
http://wiki.cocoondev.org/Wiki.jsp?page=FileUploadsWithCocoon, ignore
the rest of that page and follow the link to the 2.1 specific info.
2) Did you change web.xml in the src/webapps directory (wrong) or the
build/webapps directory (right) or some other deployed directory
(right)? There is also a build property in build.properties to set this
automatically. You can run just the config changes by changing that
setting (via local.build.properties - see INSTALL.txt) and just running
build custom-conf. See
http://wiki.cocoondev.org/Wiki.jsp?page=CustomConfigTarget.
3) Did you restart the servlet container after editing web.xml?
4) Did you say you were getting a HttpRequest? That brings up a change

First, don't confuse request attributes with parameters. Parameters are
the things that come in via GET or POST. But yes, there is an imporant
difference. Use getParameter(String key) to get at normal string
parameters. get(String key) returns Object and so has to be used to get
at uploaded Files which have been parsed by Cocoon and added to the
request parameter collection as Part objects. Use Enumeration
request.getParameterNames() (not request.getAttributeNames()! ) if you

Having 'sticky' sessions is certainly a good idea for performance reasons, but if one machine goes down in such a setup no one is affected. Umm.. someone can correct me if I'm wrong. But I believe things like sticky sessions and session replication have nothing to do with Cocoon. This all depends on the servlet container you're using to serve up cocoon correct? Also - at least from my experience with the terminology sticky sessions.. this usually has to do with a load balancer and sending requests to one particular machine. I.e. user1 connects to the website on server2 and gets a session.. from then on that session's requests are all processed by the same server (server2) until the session expires. So - I may be wrong, but I think most of these requirements that you have are probably not dependent on Cocoon itself but your infrastructure and servlet container. Anyways, in our case the servers are located at different sites, and the application is completely stateless. Well..

I'm assuming that cocoon would not completely obscure the standard HttpSession - even if it's wrapped it. Does anyone know the real story? Cocoon's HttpSession is just a wrapper around standard servlet HttpSession, but does not really give access to it. Have a look into the source code: http://cvs.apache.org/viewcvs.cgi/*checkout*/cocoon-2.1/src/java/org/apache/cocoon/environment/http/HttpSession.java?content-type=text%2Fplainrev=1.2 As the wrappedSession field has only default access and the class is even final there remains only the way of adding an additional class in the same package to get the unwrapped HttpSession - that's obviously the ugly hack. I cc Carsten as he wrote the Cocoon HttpSession, maybe he knows of a more standard way to get the unwrapped HttpSession. By the way, it's important that people know the basic reason Cocoon doesn't give you an HTTP session. Cocoon abstracts the environment so that it can be run from many different environments, not just http/servlet. Currently the command line interface is the only other implemented environment but even there dependency on servlet jar and HttpSession obviously makes no sense. Examples of other potential environments which have been discussed are email (via James) and JMS. Now, that doesn't mean it should be impossible to get to the HttpSession if you are in that environment and that's what we need to see. I think the method which is used in the other environment abstractions (Request for example) won't work here, but I don't see a reason cocoon's session couldn't implement HttpSession. Right now, it seems the only methods unimplemented from the javax interface are the deprecated methods. Another alternative would be to use JDK 1.3 dynamic proxy which may work if the code you pass the proxy to doesn't call the deprecated methods (I can't remember for sure if this is true).

Go back to the action and figure out what was wrong there. You cannot

Hello Lionel,
sorry, but I don't know why you use this complicated code to realize
uploads in cocoon. There is a solution which is very very easier!
1.) Set enable-uploads to true in web.xml.
2.) Get the uploaded file with
request.getAttribute(filename_on_the_form);
3.) After that you will receive an object of type PartOnDisk for
example. Use getFile() to receive the uploaded file.
Thats it. Isn't it easy?

This is an intentional design decision to help enforce separation of the model (content) from controller and presentation (selection of stylesheet being one aspect of those). Another aspect to this is caching which would be impossible (or useless) if processing had to start in order to figure out if a cached response had already been generated.

If you can move to 2.1 (which I would consider a must for any new development) use flow. 3) In your xsp below you only have to do a file.renameTo() to move the file - does that not get what you want?

But i need to store that file into dynamically created directory name based on the user who uploads that file. so i want to catch that File object from the FilePartFile object from the request object. But my doubt is according to wikki they are cathing that file object in action class. But i am invoking or catching in XSP file. Is this request object comes to XSP page with file object? pls clarify me? Pls look my sitemap.xmap entry and all files. pls let me know where i am doing wrong.

No, it isn't. I guess POI itself is able to do it, but it's not implemented in the Cocoon components. I've done something like this but in context just needed to put out a final document (not sax stream) and so used dom and did not implement it as a Generator. I almost went ahead and did a separate implementation for Cocoon but started feeling like the various ways one might want to interpret a series of excel spreadsheets as xml was too infinitely variable to warrant a quick solution of general use. Because my parsing requirements were complex, it would not be of general use even if I were free to release the code (which I'm not). Still, if you (or someone else) want to tackle it I could help.

Re: Cocon as a XSP parser only

First a disclaimer: I've never used XSP. AFAIK, XSP in Cocoon is a set of XSL stylesheets that transform XSP into Java. That java is then compiled end executed. The java that is created is in the form of a Cocoon Generator. If you want to extract the XSP handling, you would need to get those stylesheets from within Cocoon's codebase, and amend them to produce the code that you want instead. I've no idea how easy or hard that would be, nor why you would want to do this. If I interpret the question right, you'd have to edit the servlet mapping in web.xml - currently, Cocoon maps every request under its context root to the cocoon servlet - you could change that to some other pattern. And add whatever handlers you need for your other frameworks in there. Geoff - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
