How to make a simple news/updates list
Hi Im trying to add a simple list of text/xml chunks to my cocoon site. (which could be used for example as a list of news/site updates/guestbook posts etc.). Doing this with esql seems relatively easy, but it also seems overkill to run a database process just to keep a single list of xml chunks. Also, I'd like the site to be movable to another cocoon server without configuring any database servers and so on at the new location, that is: the data has to be stored inside the webapp directory. So far I have considered these methods: - raw xml data files. Edit file in text editor to add data, or use the SourceWritingTransformer if I need a web form. - embedded sql database (can hsqldb be completely internal to the webapp like xindice-embed is?) - embedded xindice. Haven't had any success with this, but it feels like the best solution. Has anyone seen any simple example apps (like for example a guestbook) using embedded xindice in cocoon? Any recommendations or links are appreciated... rgds Anders - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Is this a cryptic way of saying something else is wrong, or is the server actually out of memory? Has anyone else seen this?

Re: Deployment/Migration to linux
- The WEB-INF/work and logs directories are not created when the webapp loads, probably a problem with file access. What directories and permissions do I need to give to the user running the tomcat process? Well, Tomcat will be started as a specific user; I usually install a tomcat user, but this must not be the case, and is probably not even the recommended way. however: the user under which tomcat is startes should have write rights to these directories. Tomcat runs as the user tomcat. The webapp resides in a folder 'webapp' under my own home directory, so per default, the tomcat process does not have write access. As a test, I have given +rwx to all users to webapp, webapp/WEB-INF, webapp/work directories. Still, the logikit complains that it cannot create files. under webapp/WEB-INF/logs I'm not sure wether the tomcat process was started with a security policy, and I don't have access to the jakarta-tomcat/conf directory. I'd like to bother the administrator as little as possible, so I figure perhaps I should be doing my testing first on my own linux setup? How difficult is it to set up a minimal linux development environment with tomcat and cocoon? Can it be done with a knoppix or mandrake livecd? Or better yet, are there any "testbed" linux distros that installs on windows as an application?

Deployment/Migration to linux
Hi, I hope someone could help me sort out some of the problems I'm experiencing when deploying my cocoon webapp to a linux server. I'm developing and testing my cocoon 2.1 webapp under windows XP/Tomcat 4.1.29, and it works great. Now that it's done, Im going to deploy the whole thing to a server where I have my homepage account. It's a linux server, running Tomcat 4.1.27 through Apache. I have stumbled across a couple of problems, most of which I blame on not being all that linux-literate. - The WEB-INF/work and logs directories are not created when the webapp loads, probably a problem with file access. What directories and permissions do I need to give to the user running the tomcat process? - I have some small dynamic images made with svg and svg2jpeg, which will not render. I have read some things about problems with batik on headless setups, but also that It should not be a problem since jdk 1.4. Where do I start looking for the problem? The only traces of errors I can find are in the /etc/jakarta-tomcat/logs/catalina.out , where cocoon complains about not being able to create the log files. I also have some problems with xsp-actions, but I figure these errors are just following from the write-access problems (i.e. the /work directory needs to be created before an xsp will work)? Am I correct? I was hoping to be able to merely upload the whole directory structure from the windows machine to the linux machine, but unfortunately this was not the case (how naive). :) The server administrator is a busy person, and there are loads of other webapps running in the same tomcat process, so I'd rather not be experimenting to much with it either. Thanks for any pointers to 'how-to-deploy-your-cocoon-app-on-linux-without-headaches' docs.

map:parameter and xsl defaults
Hi all
I want to use a request param passed on as an argument to a transform.
The sitemap snippet looks like this:
In the log2page.xsl file, I have defaults for the parameters, for example
The default values are never assigned, which means the transform only
works when both parameters are specified in the request params. What
will the {request-param:foo} be replaced with when a param is not
specified in the request? I don't know about empty versus "undefined"
parameters, I wonder if the sitemap somehow passes an "empty but still
valid/defined" (like a "" String versus the null String) -parameter to
the xsl that prevents the defaults from being used?
If I don't use any map:params with my transform, the defaults are used
correctly inthe xsl.
Do I have to use a sitemap swicth to do the transform without
map:parameter when the request parameters are missing, and with
map:parameter when they exist? Seems like a lot of work, and also makes
the xsl defaults unusable...
Am I missing the simple solution here?

Re: xindice & xml:db samples
Hi all, How do I get the xmldb block samples working? They don't exist at the moment ... Ah I get it, I'm at the edge of the devel process :) I thought I was just too stupid to get it running Am I correct when I think that cocoon together with xindice embedded will be a brilliant sort of "self-contained" app? (i.e. the App will be truly portable, the data can reside in WEB-INF)? If so, then this should be the main benefit of the proposed cocoon-nuke: the fact that most people who want a cms or community portal can't install and prepare a dbms, a web server, and php/perl/whatever - site. Dumping a .war into the webapps dir of a servlet container would certainly be a lot easier. rgds Anders - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
xindice & xml:db samples
Hi all, How do I get the xmldb block samples working? I found this page, which is as confusing as it is new http://wiki.cocoondev.org/Wiki.jsp?page=XMLIndiceCocoon2.1 I have the cocoon 2.1.4-dev up and running, with the xmldb block included. Do I need to create the 'db' database or any special collections in the xindice db before the xmldb samples work? If so, how do I create data? Do I still need to build & run xindice from the command line to do that? rgds Anders - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: XSP/ESQL escaping
Sigh :(
Feels like a lot of work to make a linebreak a tag...If I rephrase
the question: What would be the simplest way
of displaying the database strings with correct linebreaks in html
(except using in the xsl)?
thanks
Anders
Yes, you cannot use tags inside java strings in this fashion. When XSP
sees this tag, it tries to insert a whole block of code to output the tag
into the SAX output, which should give you a compilation error.
I'm actually not certain how it is you are able to pass the results of
esql:get-xml into a function call without getting compilation errors. The
get-xml tag also turns into a whole block of code, not an expression which
can be passed to a function. What version of Cocoon are you using? In
C2.0.3, which I am using, you would be unable to do this, and you would be
unable to do substitutions inside the returned XML. Instead, you'd have to
get the results using get-string, do your substitutions (using < in
place of <), then run the resulting String through an XML parser to get it
into the SAX stream. (A good example of this is the code that implements
get-xml in the ESQL logicsheet, which is in your cocoon jar file.)
HTH.

Thanks for your time
The formatMessage is implemented above the problem in the xsp logic
section, and it (currently) only does this :
public string formatMessage(String message)
{
return instring.replaceAll("\n", ")
}
the problem area in the xsp, like I said looks like this
formatMessage()
The problem occurs when the xsp:expr contains tags (i.e. if I do the
replace "\n" ---> "foo" , then all is well, but "\n" ---> "" will
not work. )

XSP/ESQL escaping
Hi I have a problem with escaping when retrieving database data in an xsp page. For each row in the resultset, the following xml is generated: formatDate() formatMessage() The formatMessage method will replace all line breaks (\n) with the tag , however in this context that will give a an error for some reason. If I replace the \n's with >br/< etc, then it works, so it's a document structure error obviously, but I don't see why it should be?. Also, which is the best way to develop xsp efficiently? I'm using eclipse/tomcat4/cocoon2.0 on windows, and with this configuration the requests time out when there is an error in either the code or structure of the xsp, not easily debugged. Even the not-so-helpful generated code error pages would be more helpful, but they only show up on rare occasions.

Re: nuke like engine based on cocoon
I could help out I once tried using phpNuke but started hating the ugly mixing of looks and content, and the quick hack look of it all. I wanted something skinnable so I started writing a simple nuke like community portal that used Xalan and an xsl skin to show news/forums/polls/downloads/members/etc from a mysql database with "modules" producing pages and blocks from the xml content. modules can be added/removed and restricted to access levels etc. 3 months into this project i realized that half the work was actually implemented already in something called cocoon :( I am also very interested in using cocoon to make a solid replacement for phpNuke. A look of what it looked like before I ditched the project and started looking into cocoon is on this game-clan's website (unfortunately swedish) http://sheriff.mine.nu Without knowing too much about cocoon blocks, they seem like they could help a lot in the creation of such a framework... rgds /Anders this is just an idea or/and a proposition to begin a "CocoonNuke" maybe project something just like nukes (postnuke phpnuke) but using cocoon - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
