RE: PostgreSQL won't work - any ideas appreciated
From: Skip Carter [mailto:[EMAIL PROTECTED]] Once I get this figured out I PROMISE TO CREATE DOCUMENTATION :) I have PostgreSQL working just fine here.

The line in catalina.sh: CLASSPATH=$CLASSPATH:$CATALINA_HOME/bin/bootstrap.jar was changed to: CLASSPATH=$CLASSPATH:$CATALINA_HOME/bin/bootstrap.jar:/usr /local/java/postg resql.jar The dburl element of cocoon.xconf is just a reference to the database URL for that particular data source: dburljdbc:postgresql://dbserver.example.com:5432/books/dburl Having written the datasource pooling code, I am aware of what the dburl/ entry is supposed to be. I was saying that you might want to include the driver/ element with the classname to that entry in cocoon.xconf. Regarding the location of the Driver jars, there are three solutions: 1) Include it in the WEB-INF/lib directory in your webapp * It is always included with the webapp * No additional install step is necessary * Not all servlet containers respect the WEB-INF/lib contract (IBM WebSPhere moves the libs, but most current containers work properly now). 2) Include it in the $JAVA_HOME/jre/lib/ext directory * It is available to all Java applications on the machine * It is an additional install step, but simple to do. * If the webapp is moved, you have to make sure the driver exists on the new machine or new JVM. 3) Do what you did and alter the Servlet Container's default CLASSPATH. * It is available to all webapps in the contianer * It is an additional install step, and in some cases not trivial * Each servlet container has a different method of doing this, and some don't allow it at all. Of the three, 1 or 2 is preferred. 2 should only be considered for jars that are not likely to cause a conflict like a database driver. While the first option works 90% of the time, you do end up with duplicate drivers.

to try.
* Add a driverorg.postgresql.Driver/driver element into your jdbc/

* Move the library to ${webapp}/WEB-INF/libs

Subject: Access97 - Cocoon2
Hi !!
I've got a problem to access to my database Access97 under w2000. I
work with Tomcat3.3.2, Java 2 SDK 1.4 and Cocoon2.
I made an odbc link (outils d'administration/Sources de donnees
odbc/Sources de donnees systemes/Ajouter/AccessDriver/Base de donnees).
I test it with a Java program: it works well, I can read my data.
But the problem comes with cocoon :

ServerPagesGenerator.generate(): java.lang.RuntimeException: Could not
get the datasource
org.apache.avalon.excalibur.datasource.NoValidConnectionException: No

/jdbc
In my Java, I made the test with:
Class.forName(sun.jdbc.odbc.JdbcOdbcDriver);
db = DriverManager.getConnection(jdbc:odbc:bdaccess);
Does really the sitemap generate a sever page ?
sitemap.xmap :
map:pipeline
map:match pattern=spain/*.xsp
map:generate type=serverpages
src=spain/{1}.xsp/
map:serialize /
/map:match
/map:pipeline
I don't see what is bad...
Thanks for all,

Very close, except that all the XML files already identify their

this.
Not necessarily. PIs are nice, but they are not standard accross
all files. One thing that PIs don't allow is to easily retheme the
entire site without changing the existing template.
Assuming you want to change the XSLT from oldsite.xsl to newsite.xsl
and still keep the old XSL file for archives--or to switch back to it.
PIs force you to place the information for oldsite.xsl in every XML
file. If you forget to change one file, it will stick out like a sore
thumb.
The new way allows you to change all files in one place. If you have a
chain of XSLT transformations--you can easily apply it and *KNOW* the
chain. You don't have to generate PIs in subsequent XSLT layers.

Re: Serving static XML files a la Cocoon-1
Peter Flynn wrote: You don't understand the Cocoon2 concepts at all. I think you are deeply mistaken :-) It is nonsense to serve XML files with their XSL files : This is rubbish. Leave aside non-valid XML, as I don't use it. All valid XML documents adhere to a DTD by definition (omit Schemas, they're not relevant here). Each DTD has a stylesheet to render documents of its class. I require to serve the XML documents processed with the relevant XSL stylesheet into HTML. Each XSL stylesheet belongs to a DTD: that is, it is written to render documents written to that DTD. Key distinction: DTDs are used to *VALIDATE*, not render. the principle is to separe data and presentation, ie XML source and XSL. Absolutely correct. This is what I do. I have a large number of XML files and a very small number of XSL files (one stylesheet per document type, modulo development). Each document type (in effect, DTD) has one stylesheet at any given point in time, so that all documents written to that DTD are served in a uniform format. Over time, a new format may be developed, at which stage it will be useful to be able to edit the sitemap to make all XML documents of a given type to use a new stylesheet. But this is a once-every-few-years task, not something I change every five minutes. True, but it is not uncomon to have a working stylsheet in applications, and before release the web monkeys are let loose to make it look nice. Of course both these developments can be happening simultaneously. THe doc writer should not care how the info is presented, that isn't their concern. So you have to write a pipeline (or to copy/paste one from an existing sitemap) to generate HTML stuff from XML by transforming it through XSL. The sample sitemap bundled with Cocoon offers these 'defaults' already. If that is so, why does it not transform my sample XML document with its accompanying XSL stylesheet? Are you volunteering to write something that reacts to PIs? It's not really a trivial task, and considering the amount of work involved in it, for something we really don't want to encourage, its not a likely thing to happen soon. Going back to your associated XSL document, and distributing the files w/o a server: you can still do that with your PIs. A browser that knows how to treat the PIs will do so correctly. However, for serving up to older browsers, you should use the preferred method. Your Sitemap won't change much. You stated something like every few years. When you change your site, you only need to update the sitemap to point to the new stylesheet--even if you have hundreds of documents by then. -- They that give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety. - Benjamin Franklin - Please check that your question has not already been answered in the FAQ before posting. http://xml.apache.org/cocoon/faqs.html To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Our solution - which, in my opinion, is not really good - is to tell the html serializer to generate output in the ISO-8859-1 character set instead of the normal UTF-8 character set. Then all the data, which is serialized to html stays in the ISO-8859-1 character set, which has been read from the database.

No, that is so that Cocoon can compile the Sitemap and any XSPs properly. Remember that Cocoon does alot under the hood. While there is an effort to convert the sitemap to an interpreted file instead of compiled class, it is not *quite* done yet. The initial reports are encouraging. It beats out the compiled sitemap in some tests, but their performances are fairly comparable overall.

Re: using Cocoon WITH Cold Fusion
Lisa Bos wrote: Have read a lot comparing CF to Cocoon, but I have a different need: I have a client who is using Cold Fusion. Client wants to start using XML + RDBMS for content management. Wants to continue using CF for Web. We have no control over this decision. Their content today doesn't change frequently. Overnight updates are fine for most data-driven pages for now. (In other words, performance isn't yet a big deal for them.) Some text content would need to be updated more quickly. BTW - They do publish rather large, structured docs to their site, which is the primary justification for the use of XML. I feel your pain. I hate CF for it's inelegance, nad have been the source of most of the comparisons. My broad question is: What's the best way to manage the delivery of XML content to Cold Fusion (in combo with data from Oracle)? Need to generate CF and plain HTML pages (we are talking simplistic use of CF here). Definitely want to use XSLT, but its the larger management issue that concerns me. If your team is amenable to overnight updates, you would have to use Cocoon at the command line. You can use a cron job to invoke it, but basically, that is what you would have to do. CF would access the static files. To allay management's fears, if you have *any* spare time, write up the stylesheets to display the XML just like the current site. Set up a Tomcat server on your local machine, and give a demonstration. If your management is technically inclined (as mine is), show how much more elegant the code looks compared to CF. Here is the real kicker: compare the install times of a CF based application and a Cocoon based application on comparable hardware! ColdFusion forces you to enable options on your server that make it vulnerable to certain attacks. Most Servlet Containers like Tomcat and Resin do not force you into the same position. Furthermore, in a DMZ, all communications accross boxes must be encrypted. In CF you are limited to an easily crackable 56 bit encryption, while most J2EE solutions give you 128 bit or better encryption. Just a few points that will help convincing management. More specifically for this list: Is Cocoon a reasonable choice for this application (knowing ahead of time that this might be a somewhat goofy, redundant approach)? It depends on the long term goal of the project. If your bosses are more like the Pointy Haired Boss in Dilbert, then just stick with CF, because you can't convince them. If your boss is concerned with security, ease of installation, and cross platform stability, you have no choice but to use something based in Java-- so why not Cocoon? Trust me, I went through a nightmare install of CF on a hardened Solaris box. It took roughly six months--and once the thing was finally working, the project was dropped. That is _bad_ for business. One goal is to choose an approach that will make it easy for CF to go away at the right time, and that is straightforward in its handling of XML/XSLT/etc. Might still be a limited number of CF pages that pull data directly from database, but those could be transitioned over time as the client is convinced.

You do have to make sure the JDBC driver for MySQL is in the classpath.
If you include it in your ${webapp}/WEB-INF/lib directory, make sure
the jar file ends in .jar because many servlet containers will not load
.zip files. If you include it in the ${java.home}/jre/lib/ext/ directory,
it will be available as well. I would highly recommend *not* placing it
in the ServletContainer's lib directory, because the current Servlet
Containers separate the classes used for the server from the ones used
in the webapp context.

notice your code being more performant:

Re: How to offer cocoon virtual hosting?
Larkin Cunningham wrote: My query relates to how one goes about offering Cocoon through virtual hosting. I have Cocoon 2.0 installed on one of our live web servers alongside Apache and Tomcat 4.0.1. I have Apache talking to Tomcat talking to Cocoon. I have mounted the installed cocoon webapp under $CATALINA_HOME/webapps/cocoon to a context for a single domain (say for now www.thedomain.com). I can now access www.thedomain.com/cocoon/welcome and I see the usual welcome page and I can look at various XML, XSP, FOP pages, etc. So far so good, but how do I go about offering this on a virtual basis? The documentation for cocoon is fine, but doesn't really address virtual hosting (at least I don't think it does). If its there then I wasn't able to understand it. This list and the archives tend to be geared towards single site web applications. And there are very few web hosting companies offering cocoon so there hasn't been much from that direction on this list. Are you referring to multiple hosts like this: http://www.thedomain.com/ http://foo.thedomain.com/ http://bar.thedomain.com/ or are you referring to getting rid of the /cocoon/ in front of the URL? I am using mod_jk (ajp 1.3) for getting apache to talk to tomcat/catalina. I have included JkMount /cocoon/* ajp13 as part of httpd.conf. As part of server.xml under the Host entry for www.thedomain.com I have: Context path=/cocoon docBase=/opt/jakarta-tomcat-4.0.1/webapps/cocoon debug=0/ This is fine for getting the samples to work, but where do I go next for virtual hosting of customer web applications? Can I change the docBase to a directory within the virtual site space and get XML processed by Cocoon by having the correct web.xml within WEB-INF? When you say Virtual hosting, you are mixing what a webapp is for and what a web server is for. You follow your web server's instructions for virtual hosting, and then place the directive for mapping requests to the webapp from there. Any help appreciated. Once I am fully happy with this I will get the site added to the cocoon hosting page.

The Janitor is used to check the Cache and the memory to remove things from cache if necessary. You can get rid of DEBUG messages and gain an appreciable differece in performance, however you may want to try a couple of other things first. Is your JVM set with the following params: java -Xms64M -Mmx128M? This keeps the JVM from using more than your physical memory. Remember, it is cheaper for your JVM to manage your memory than for your OS to cache to disk. Also, do a search for the word Exception in the contents of the files in the log directory (I think you said you were on windows). If you see any concerning your database connection, that can hurt performance. Play with your cache settings. If you have your cache set at 512M when you only have 128M available, your cache might try to use too many resources--slowing the garbage collection cycle. Also, you didn't answer my first question: Is this 45 second access only for the first time you access the page, or _every_ time you access the page. Remember that the sitemap and the XSP pages must be compiled before they can be used. This means the XML is converted to a Java source file, and then compiled with javac. It is not uncommon for it to take as long as 45 seconds on a resource constrained machine (these days 450MHz and 128MB are considered small) to compile. However, after the first access the page loads are lightening quick. Another thing to examine is if the timestamps are being altered during regular serving. If so, the page might be compiled every time the page is requested. -- They that give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety. - Benjamin Franklin - Please check that your question has not already been answered in the FAQ before posting. http://xml.apache.org/cocoon/faqs.html To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

This combination worked fine if I ran Xvfb. However, I noted that some of the examples don't work quite right; some of the SVG examples appear differently than they do when I substitute the Sun jdk1.3.1 for Linux for jdk 1.4. OK. You will have to recompile Avalon and Cocoon using JDK 1.4's compiler. Reason being is that they make special consessions for the JDK. I'm curious how other people have managed to use jdk 1.4 on their systems. Can any of you provide the actual startup scripts you use to make this work?

Re: New Cocoon 2B1 powerred website
[EMAIL PROTECTED] wrote:
Dear Cocoon users
We would like to invite you to view our newly released website based on cocoon2 and
turbine at the URL below.
http://www-eng.tp.edu.sg
A brief about the web site and CMS system.
We have built a Content Management System(CMS) for over 60++ content publishers using
Jakarta Turbine for the admin module to organise/manage their web pages. Turbine also
provide the access control portion. Velocity was used to develop the screens for CMS.
Users use MS Word to prepare their documents/content. These pages are then uploaded
by CMS from the desktop to the server. At the server we use logitran to translate the
MS Word document into a temp XML format. We then use Cocoon to translate it into a
predefined XML format. Display templates are then used to generate HTML pages for the
browser under Cocoon.
The configuration is such that the CMS system is sitting on one server where all the
publisher will use it to prepare and preview their web pages. Once confirmed/approved
the approved pages would then be replicated to the producton/live server.
The CMS system is running on a Win2000 adv svr,logitran 5.4.5, apache web svr, tomcat
3.2.2 and mysql, turbine 2.0, velocity and Cocoon 2 beta 1. The live system is
running on a Win2000 Adv server(Compaq 1GHZ twin CPU server w/1GB RAM), on Apache web
svr, Tomcat 3.2.2, MySQL, Cocoon 2 beta 1 and Turbine 2.0.
We have had many challenges in getting the system up and would like to Thank the many
people in this newsgroup and Turbine who have been helping me and Kok Choon. Many
Thanks also to David from Logitran. We hope that this announcement would inspire
others to have the confidence to use Cocoon under a live environment.(our website
currently have 400 pagesnot bad for a start) The real benefit is that the
lecturers now can conveniently use MS Word to prepare the content and our system
using CocoonTurbine takes care of the rest. No more HTML or waiting for the web
programer to punch out the code. A big Thank You to the Cocoon and Turbine Gang.
The workis not over yet. Other than enhancements we are having some problems. Any
assistance would be much appreciated of course:-
1)Netscape support for Cocoon. Kok Choon is having problem getting his java script to
work with his Cocoon generated code.
The sympton is as follows. point your netscape to www-eng.tp.edu.sg
1. First time connection to the website using netscape 4.78, sidebar function does
not work. You will have to reload the frame.
In this case the JVM is out of memmory
2. After refreshing, the sidebar appears, but the content window will be filled with
funny chars shaped like little square boxes replacing the text content. Of course, if
you copy these square boxes and paste into notepad, the actual text does appear!
Don't use UTF8 encoding. Use an older/more traditional ISO-8859-1 encoding.
Netscape doesn't play nice with UTF8
According to our programmer, Kok Choon , the web pages rendered in Cocoon is not
supported by Netscape 4.78.
That would be more of a function of the end markup used. If the markup is not
friendly, and the encoding is not friendly (both can be controlled by Cocoon),
then thre result won't be what you expect.
2)we are encountering some performance issue due the model of elements used in
Turbine. (Turbine groups are used to model the folder, web pages hierarchy) Any Gurus
out there who would like to discuss this plse contact me.
Check the RAM resource requirements--Your servlet engine is overloaded.
Any assistance on how to fix issue this would be much appreciated.
Thanks in advanced for all your kind help... Attached are the 2 style sheets used in
the aggregation of the web page.

Questions: Is your class in the compiled jar? Is the compiled jar in your WEB-INF/lib? Are you trying to provide an Action for the Cocoon distribution? The last question is for the package you chose. If you are writing an action for your own app, don't use the org.apache.cocoon packaging. Use your own package--its better in the long run. In the Sitemap, you have to put the fully qualified ClassName to use your Action--so feel free to use any package that makes sense. If you place all your application's actions in org.apache.cocoon.acting, you are going to experience maintenance problems when someone else upgrades Cocoon and wonders why the webapp is broken. For your own stuff, either use the WEB-INF/classes (prefered while you are developing), or place it in your own jar in WEB-INF/lib (preferred for deployment).

Re: Fastest Platform (softwarewise)?
Phil Blake wrote: Hi, We run apache/tomcat/cocoon on 3 server platforms, Linux, AIX and MacOS X. Linux on a dual PIII 550, OSX on a PPC-G4 450 and AIX on a 4x250MHz PPC-G3. Bang for buck, a G4 running OSX wins hands down. However, believe it or not, the dual PIII comes in second (AIX don't come close... too expensive for real consideration and Windows is not a server operating system in practice, only in marketing). That's interesting, I didn't think OSX would come out on top--maybe second though. As to AIX, and this goes for Solaris as well, they are very expensive--so bang for the buck goes down. How about raw performance though? Which comes out on top? The Dual PIII was about 10% more than the G4 (after adding SCSI) and about 70-80% the performance. So for 10% more cost you gain 70-80% more speed. That is a reasonable tradeoff. What kinds of tests did you run? How does each one scale (as you add more clients). How many simultaneous connections can each platform handle before you reach saturation? Although theory has it that a G4 500MHz has about the same performance as a PIII 1.5GHz (ie triple the performance), I've found that it's really more like double the performance, not triple. Careful there. Clockrate != performance. When all things are equal (i.e. chip architecture, design, etc.), then clockrate is effective to determine relative performance increases. However, the G4 and the PIII have very different architectures. This is true of the PIII and the P4, and the P4 and the K7. In that case 1.5GHz in all three processors would have very different performance results. As far as I know, the G4 is not capable of the high clockrates, so it makes up for it with an efficient pipeline. The pentium series was designed for high clockrates. - Please check that your question has not already been answered in the FAQ before posting. http://xml.apache.org/cocoon/faqs.html To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Alexander Schatten wrote: I tried to use C2 for publishing XML through XSLT basically this works when connecting with IE5 or Opera 5, but not with Netscape 4.7 the behaviour is very strange: Netscape displays nothing (white page), but when I go to show source it displays the html code correctly. again more strage: when I try: Save as... and save this html page, netscape does not render to disc, then load it with the same netscape browser window, it is displayed correctly??? Try serializing it as the mime-type text/html. This allows Netscape to treat it like HTML--even if it is XML. Netscape does not natively handle XML, so it does not even try.

Re: [C2.0b2] - ComponentManager
Adrian Geissel wrote: Hi, We looking at migrating our application from C1.8.2 over to C2. In C1.x, we used Turbine for connection pooling, and we need to move over to the Avalon CoponentManager framework. There was one real advantage in using Turbine, where there is a singleton-access to the connection-pool, thereby allowing it to be easily integrated with external code. Basically, we have a tried-and-tested database access library that takes utilises an internal ConnectionFactory that calls into Turbine for its connections. I have not found a similar factory method for accessing either the Cocoon object, its ComponentManager, or any managed components. Have I missed something, or is there a preferred approach? A non-singleton access to the connection pool will require a potentially reasonable coding change. Also, having a little difficulty in configuring a pooled connection to PostgreSQL - I've followed the instructions in the 'datasources' document, but the ComponentManager complains that the named component cannot be found.

Re: Getting read of the X server dependency
Jon Peterson wrote: Xvfb is what you need. If you're running Linux, you may already have it available (do which Xvfb or slocate Xvfb to check). If not, go to Xfree86.org and download either the Xvfb component of X (if you have XServer installed) or grab the entire X Server and run Xinstall.sh. If you're running Solaris, go to http://tmap.pmel.noaa.gov/home/ferret/FAQ/graphics/Solaris_Xvfb.html for the binaries. That takes care of part of the problem. Please, I highly recommend stress testing that setup. Any time you are dependant on the interactions between two highly complex beasts (JVM and X windows server), there are bound to be synchronization issues and other bugs that are beyond the control of Cocoon! Consider the load you are expecting, and test for twice that number. It is more important that you test for concurrency than for sequential access. If you expect 100 simultaneous users during peek time, test for 200 users. Use realistic settings, but test nonetheless. Keep in mind that any time you incorporate SVG using FOP or Batik, then you are going to use the X windows server. If you have _any_ serializers that use Batik (i.e. svg2png, svg2jpg), you are going to require the use of Batik. In some instances the setup will be perfectly stable--but some platforms will prove unstable. It all depends on the implementation of X Windows and the implementation of the JVM. When JDK 1.4 becomes stable, the promise of Headless servers will be realized, and Batik can be used without precaution. Once installed, on the command-line run /usr/X11R6/bin/Xvfb :1 -screen 0 1152x900x8 and then set the DISPLAY variable to :1.0 This should take care of your problem and allow you to keep batik's functionality.

Re: Cannot get a Poolable before pool initialized
If you have a version of Cocoon that is compiled with the latest Avalon jars (Excalibur/Framework/LogKit), you can add in the element drivercom.company.jdbc.CompanyDriver/driver and have it loaded that way. Otherwise, you _must_ load your driver with the load-class initial parameter specified in web.xml. Check the FAQ. Also, with the next version of Excalibur, you will get better error reporting so that it will tell you what to do.

Re: Fully exploiting Cocoon
Why do you feel you have to keep them synchronised. If you have a number of resumes that all conform to your resume.xsd markup, then they can all work through the same stylesheets. If your stylesheets are written to accept the same markup, they can be used interchangeably for whatever your desired result is. That means that if you have the source files: * siegried.xml * roy.xml That conform to the resume.xsd schema (which does not have to be used at runtime BTW). Then both stylesheets below will be able to process both xml files above: * resume2xhtml.xsl * resume2fo.xsl That means that you can have two outputs for every one input. If you had 20 resumes, you only have to keep the one source file for each managed, and the two stylesheets managed. Now, instead of having to manage 40 different files (1 PDF and 1 HTML for each person), you only have to manage 22 files. The trick is be smart about how you set things up. If there is some extra information that you want to show up for PDFs and not for HTML, then you design the resume2xhtml.xsl file to ignore the elements that you want ignored. --- Richard Heintze [EMAIL PROTECTED] wrote: Wow!

Any other suggestions? Please don't use MS Access. Microsoft will never lift a finger to support Java--so none of their databases will have a JDBC driver. The Cocoon website is not a place to find information on drivers, so you are on your own to find a decent JDBC compliant driver for MS Access. There was also a recent discussion on this list regarding the JdbcOdbcBridge driver that Sun provides in its JREs. You can't really use that for technical reasons that I really don't want to get into right now. Here is my experience with Access in general, and why you should never develop with it for serious solutions: * MS Access allows you to be lazy, and will keep working even when the database is not set up correctly. This means when you plan to move the database to a real RDBMS you will have to rework your database and ultimately your code. * MS Access SQL is not standard--esp. concerning dates. If you access custom code (aka modules) from Access SQL statements--you have to rewrite the query when you migrate. * MS Access table structure is to easy to manipulate. Many fledgling companies think that this is an asset--as did mine before I joined. What this results in is each developer with a slightly different schema and code that won't work universally. * MS Access has no security. Anyone can access the data and manipulate it. It's so called security layer is easy to circumvent and only serves to lend a false sense of security. * MS Access cannot be centrally managed in an effective manner. It is true that you can send out replicated databases--but in practice replecation has proven to be both unweildy and still does not address central management of the database.

Oh, I thought it was only fair to mention that the ODBC version went to Access which is a poor performer anyway. The combination of the ODBC Layer and the slower database caused such a large difference in performance times.

Dinkar Ganti wrote: Hello: I checked my application and it is able to connect to using JDBC-ODBC driver on Java command line. However, when I use Cocoon, I get the following exception trace. Any pointers to this type of error will be greatly appreciated. Short answer: don't use JDBC-ODBC bridge. Long answer: Cocoon uses Avalon's connection pooling which keeps connections open until you need them. This greatly helps in the scalability of web sites, however the JdbcOdbcBridge is neither fully JDBC Compliant, nor threadsafe. Many times it chokes up on more than one open JDBC connection. There are a number of anomalees with the JdbcOdbcBridge, so you can NEVER do connection pooling. Your ONLY option (if you use the bridge) is to create and destroy your connections as you need them--which precludes you from using the actions included with Cocoon because they require you to use connection pooling.

Re: cocoon comparison with dom4j
In one word: flexibility. Cocoon is an incredibly fine piece of work, and it allows you to do things that you would otherwise have to write yourself. It comes down to maintainability. If you have a small site, taking care of transformations yourself is probable the quickest way to go. However, if you have to do anything remotely complex (like backing to a database or other external resource), then you will appreciate all that Cocoon can offer you. You have database connection pooling, caching, multiple transformation pipelines, successful separation of concerns. All of these things only scratch the surface.

Re: Cocoon2 - bad performance with increasing amount of clients?!
Andreas Engfer wrote: First off, what are your typical response times on the server (recorded in cocoon.log as INFO messages). Also, for production, it is recommended to pregenerate your XSP files, and make the appropriate settings in Cocoon.xconf so that the ProgramGenerator does not try to compile your XSP and Sitemap. How does this affect things? For simple transformations I have seen response times of 20 ms or less (if served from cache 0 ms) per page request. I use Tomcat 3.3m4 because it is better designed for speed. You may get better results with Caucho's Resin. My machine is an Athlon 750 (you never mentioned the speed of your processor) with 256 MB RAM on Win2000 and Sun's JDK 1.3.0_02 HotSpot Server. I have bombarded my machine with 20 users, and the response time stayed around 60ms a request or less (the welcome page on C2 samples). Also note: make sure you have the oradb attribute set to true in your pool-controller/ element for your database settings. Hi all, I am testing Cocoon2 with the Distributed Application Tester of IBM and I made some surprising experiences! Start testing my whole application (XSP Pages, connecting and using an Oracle DB - - - with connection pooling - , applying stylesheets -.xsl - for the rendering of html) with an increasing count of clients - the average response time grew up linearly with factor two. I assumed that working with the database causes the linear increase of response time. But neither testing the application without database connection, nor testing only the main page of the given examples of cocoon2 were different. Tthe result was the same: Client increase (+1) causes the double average response time. In addition to it even one client needs the whole CPU with a java process. I guess, with these results Cocoon2 is not usable in a production environment with a large amount of users: the more users - the longer the response time, starting allready with two users ???!!! Has anyone made the same experiences or can tell me what I made wrong? I would be pleased to hear from you. My system is constituted by Tomcat 3.2 with Cocoon2.

Max Larsson wrote: C2 delivers resource not found. It's not a problem with the LoginAction class. It gets loaded and executed without any problems. I can post the source if needed. Oh, quick question: Does the Action return a Map? If an action returns a null, it is concidered to have failed processing, and nothing embedded in the action will execute. This probably needs to be better documented. An action must return a Map if successful--even if it is empty. S/MIME Cryptographic Signature

Mariano Kamp wrote: Hi there, after deploying it the first in production c2 is not working anymore. This due to the reason that on the production machine is no xserver running. I remember having seen this on the list already and that there is a workaroung, but after searching the mail archives for more then 15 minutes without any success I would appreciate if somebody can point me out to the right keywords to look for, or even more appreciated, tell me how I can run cocoon on a machine without X. Either install a X server Virtual FrameBuffer, or do not include Batik (which requires that the svg2png and svg2jpg serializers have to be removed from the sitemap along with any resources that use them.

JDK 1.4 Beta has a number of surprises that hopefully will be taken care of in JDK 1.4 Beta Refresh. I also do not recommend Beta JDKs for production use-- though you should consider them for development. It will help you prepare for new APIs without breaking backwards compatibility.

Re: [C2.0b1] bug(?) in XSP
Drasko Kokic wrote: Okay ... after a small (but very eficient) chat with javaguru ... I have identified background information about the way where the generated java file is being created: It seams that the informtion suplied in the src atribute of the generate element is used to define where (relative to .../org/apache/cocoon/www) the file will be created. There is a possibility in a multiple sub-sitemaps environment to have same relative paths for diferent XSP's in different sub-sitemaps. This means that either the files will overwrite each other all the time or (even worse) be mistaken!!! The generated class files are placed in a main package which you can override in cocoon.xconf. By default, it is the package org.apache.cocoon.www. From this point, all class names and sub packages are generated from the filename of the source document itself. In fact, the extension is made part of the class name. For example, the root sitemap.xmap file will be generated into: org.apache.cocoon.www.sitemap_xmap; If you have two other sitemaps that vary only by extension (for instance .map, and .alt) they will have a unique file and class name: org.apache.cocoon.www.sitemap_map; org.apache.cocoon.www.sitemap_alt; Also, since the actual class/filename is derived from the context directory, the sub directories are treated as sub-packages, and illegal characters are transformed into an '_' character. The only potential conflict that remains then is one where you have two identically named files in the same directory that differ by using a period (.) instead of a hyphen (-). Niether of these characters are legal class name characters. For example, we can have the following files: file-one.xsp and file.one.xsp: org.apache.cocoon.www.docs.file_one_xsp; // docs/file-one.xsp org.apache.cocoon.www.docs.file_one_xsp; // docs/file.one.xsp It is theorhetically possible--however the circumstances to create it would require a developer who doesn't give a flying leap about maintainance. Since Contexts cannot be written to by an outside user, we are safe from this approach. Please, could somebody give some light on this problem?!

Unfortunately the first time I have solved the problem in untraceble way :-( I am using submaps like following context = KontoCheck submap = LOOP this creates properly the sitemap_xmap.java in the blabla...KontoCheck/org/apache/cocoon/www as well as in the subdirectory LOOP. Both get compiled and things work fine. BUT ... after I have configured the LOOP submap to serve the URI SingleLogin/CheckIn I am getting the ClassNotFoundException. Looking into the work directory I can see that under the www directory there is SingleLogin subdirectory containing the java file generated thrue XSP. ONLY THERE IS NO CLASS FILE.
