From your posts, looks like your are on a windows machine. I guess postgres is running on a Linux machine. Webmin is running on the same server where you have you postgreSQL server.

Re: building Collection from JDO problems
Antonio, thanks for the help. The funny thing is everything worked fine getting one record. I used the ojb sample and modified that to use my database and table. I then tried to modify the bean and DAO class to return a collection instead is strings and integers so I can build a list instead of a simple record. The Collection is filled with classes of the same structure as the original bean. I also modified the repository.xml file to point to the new class instead of the bean. Of course the form was adjusted to accept the Collection and return the different records. When I fill the Collection manually the form works fine. I checked all the variable types and can not find anything wrong. :-/ AFAIK There is no example of a database filled list Woody form using flow. Any ideas on how to perform tests?

It is good to know there seems more behind this problem then just a small error - played to long with this problem to be just easy to solve. :-) It seems it has to do something with the html tag combined with the XHTML namespace. I tried your things and had the same results. I found this point what might has do somehting with it: http://archives.real- time.com/pipermail/cocoon-devel/2003-May/013622.h tm l That issue has been fixed for a while: http://nagoya.apache.org/bugzilla/show_bug.cgi ?id=19423 It refered to the fact that you couldn't use the xmlns() stuff in xpointer expressions. I am using Xalan 2.5.0. Is this maybe a reason? Xalan does however indeed have something to do with it. To build a DOM from SAX events, we use the trax API whose implementation is provided by Xalan. And I know Xalan does different stuff for HTML then XML, and does this by checking the root element. The only thing I still have to find out is what it does exactly do different here. It must be something with the DOM it builds (since two completely independent XPath implementations can't handle it). I can't promise when I'll be able to look into this further. Maybe some evening this week. If you want to have a look at it yourself, the DOM-tree is made in XPointerContent.getDocument() and the XPath is evaluated on this in XPointerPart.process(). I tried it the last days with Xalan 2.5.2 but it didn't work. I also tried it with Xlink but the same error ocurs. With java I am unfortunately not experienced enough to go to deep in the above mentioned functions. I am going to investigate the next days further but honestly I am quite hopeless solving this problem myself and think about changing to something other then xhtml files.

Re: Best practice for database manipulation?
Hi Bertrand! FYI, I recently put some thoughts to paper about implementing business logic in Cocoon, I've posted a summary on my weblog at http://codeconsult.ch/bertrand/archives/000242.html I have read your summary and I think it is great. First question: Is the paper the summary is based on Open Source :-) ? I really like the idea of having a Avalon component acting as a facade of the business logic. Actually I have been playing around with this kind of architecture and it works great for me. Right now, my facade and the business layer are on the same machine, but in order to have my application distibuted I would like to connect the bisiness layer via RMI and/or SOAP. So I have to extend my facade with those facilities. Are there any helpers within the cocoon distribution or do I have to implement the RMI/SOAP stuff myself? Does anybody have gained some experience in this area? Any advice is greatly appreciated. My architecture: Flow Controller: calls the facade, delivers business objects to the view Facade: Avalon component, calls the business logic business layer: Java classes persistence layer: JDO (very slow) / ODMG Best Regards, Bastian - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Other than that, my advice is to put your database access into a java class (better: Avalon components) and access it from flow. If This sounds like a good idea. I've been studying several *.js files and I get a general idea of how it should work, but...what do I get from building my classes into Avalon components and... what should I do to convert my classes into Avalon components? I cannot afford to spend a considerable amount of time to study yet another framework. You gain flexibility and if your classes hold state or configuration, the Avalon component manager (soon service manager) manages them for you. The pattern is to define an interface as contract to fulfill and configure at startuo time the right implementation to use. Avalon provides a number of lifecycle interfaces that allow the manager to setup your components. E.g. give access to other components or pass configuration data to them. It also manages concurrent access to a component by instantiating additional ones, pooling instances or sharing instances across thread depending on the marker on the component. Cocoon is based on this principle and whenever you access a generator for example, the Avalon component manager directs the play. If your classes don't have any such requirements, converting a normal class to a component is to a) create a corresponding interface b) add a ROLE constant to the interface as individual name c) declare your component in cocoon.xconf using component-instance/ d) access the component from other components that implement the servicable interface. (your component gets a reference to its managing component manager) e) use manager.lookup(YourInterface.ROLE) to access it f) release the component when done using manager.release(myComponent) d) does not apply for flow e+f) there are methods on the cocoon object in flow for this. Avalon is very easy to program to. Chris. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: woody, flow and database confusion
Hello Bert, it seems we went exactly the same route this week. Maybe we should put together our efforts to get this thing working and to help other people with a wiki page. I only don't have that time til beginning of March because there is still an exam to be passed. So let me write a short mail about my experiences. We have at least our own application running with OJB. We can retrieve lists or single objects from the db and display them with Woody, we can store them back and delete them. We only have still a problem with object identity, so that storing does indeed create a new object in db, but that's another problem we didn't have a closer look yesterday evening. The way to this was long and stony, so you are not the only one :) We started also with OJB/JDO and had bad feelings when we saw that we have to maintain at least two files (package.jdo, repository.xml) to get it working. The reason for it is that JDO and OJB are two different products, OJB provides only a plugin for Sun JDO at the moment, but both must get their configuration. Though it's easy to write a stylesheet that converts one format into the other I tried to use only JDO. But JDO is just the API, the SPI must be provided by the database vendor and as there are probably not that much for a specific at the moment, you need OJB. Then we found out that the JDO implementation has a performance problem: Retrieving 20 rows out of 6.000 in a db leads to instantiation of all 6.000 objects, they are filtered by JDO. That's not a problem of OJB, it's just how Sun JDO works. So we were back nearly to the beginning. We decided to go on with OJB (as it allows easy switch between different persistence frameworks (JDO, ODMG, OTM, PB)), but used the OTM. This one provides also object level transaction. Now the application itself. I don't love the idea of accessing the persistence layer from the flow/controller layer directly. We access it only from the application layer to have obvious tiers. We have a DAOFactory that returns DAOs (e.g. either JDO or OTM), the implementation of the persistence framework access is abstracted. In theory we can switch to Castor, Hibernate or what else without touching the application layer. Each object specific DAO will provide different methods for retrieving, storing, deleting etc. As the layers below the flow layer are no Avalon components and not in relation to Cocoon, but Plain Old Java we kicked out Cocoon OJB block completely and just use OJB. If this was a good decision we will see. But it won't be that difficult to switch the datasource back to Avalon/Cocoon in OJB properties file. BTW, we package all classes, configuration files and so on into our application JAR, deploy it in WEB-INF/lib and it works without any problem.

I have created a bean to store all form data. The Woody form and the FlowScipt have been created too. I have used the obj/woody sample as a template to get things running. That's the easy part (relatively speaking). I'm using mySQL as a databasource and have a datasource configured in cocoon.xconf. This datasource is used in XSP pages using ESQL without any problem, so that works for sure. My biggest confusion is where I need to configure the link from the bean datastore to the database. Where do I configure OJB and JDO? I have OJB.properties, package.jdo, repository.dtd and repository.xml in the WEB-INF/classes directory. I see a total overlap in the configuration in the package.jdo and repository.xml file. Why is that? Is either of them not needed? I have created a DAO class file too. This is a direct copy of the Employee_DAO class file from the samples. I only replaced the package and replaced the bean methods with the ones from my bean. All this compiles without any problem. The bean and the DAO class are packaged in a jar file and put in the WEB-INF lib directory. I assume this is where I will eventually create queries using OJB code to fill the bean with data.

Re: building Collection from JDO problems
I saw in your flow script:
var dao = new Packages.be.bvar.admin.links.LinksDAO();
but in your Java file:
public class linksDAO {
Just a typo?
No, it is not a typo and probably the reason why I have this problem.
I'm not going to repeat what I was just shouting, but it wasn't pretty.
Like always, the problems that are the most difficult to solve are the most
stupid problems made.
I still have to test it, but I'm sure this is at least one problem solved.
I'll see where I get now. I have another obligation at the moment (family).
Thanks a lot all for your help and explanation. I will type out (a) step by
step Wiki page(s) to explain on how to set up Flow/Woody/OJB. There's no
need for other people to go through my ordeal (even though they probably
won't make the same stupid error as I made).

Incomplete image requests
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=src>artistImage//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=center>xsl:apply-templates select=//artists-photo1/>/td>
/tr>
tr>
td valign=top>xsl: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 Andrew,
maybe you have inside your html-source image width=

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

Huh? You have two wildcard tokens in your pattern and reference only the second and the non-existant third. Did you type wrong?
The image link is built up in my xsp page as:
artists-photo1>
xsp:element name=img>
xsp:attribute name=src>artistImage/1/xsp:expr>artistID/xsp:expr>.jpg/xsp:attribute>
/xsp:element>
/artists-photo1>
And here you are referring to an image source which looks like it would be matched by a pattern like artistImage/*/*.jpg in your sitemap, but you don't appear to have such a pattern matcher set up. Is this really what you're using??
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?

The only mysterious thing here is why the first image works at all given the above data.

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?

RE: Best practice for database manipulation?
Hi Christian, This all sounds promising and it's not that I don't want to do the work, but I'm very pressed for time so if I explain what my classes do (at least the simplest one) could you give me a hint as to which part of Avalon I should study and/or copy from (i.e. copy and adapt)? Here we go: what I basically have/need is the following: Objects passed around are persons, i.e. a set of data belonging to 1 person. I create a (Corba) connection to the server (I have 2 of these) by providing a servername, namingservice address and some extra settings. I can pass several types of queries which result in data that are processed in a separate class to something that is more easily manageable by Cocoon. I get stuck when trying to convert the modified XML (through a Woody form) back into a structure readable by the server for storage. The following situations need to be handled: 1. if data is not modified, don't store 2. if data is modified, store, pass on success or failure 3. if new person's data is stored, check for duplicate, pass on success or failure In all cases success or failure should be indicated on a page that also displays the (updated) person's details. When writing this I realise this looks a lot like access to a regular database, so maybe you can tell me which classes I can study best? Thanks and bye, Helma -Original Message- From: Christian Haul [mailto:[EMAIL PROTECTED] Sent: Monday, 16 February 2004 13:51 To: [EMAIL PROTECTED] Subject: Re: Best practice for database manipulation? Other than that, my advice is to put your database access into a java class (better: Avalon components) and access it from flow. If This sounds like a good idea. I've been studying several *.js files and I get a general idea of how it should work, but...what do I get from building my classes into Avalon components and... what should I do to convert my classes into Avalon components? I cannot afford to spend a considerable amount of time to study yet another framework. You gain flexibility and if your classes hold state or configuration, the Avalon component manager (soon service manager) manages them for you. The pattern is to define an interface as contract to fulfill and configure at startuo time the right implementation to use. Avalon provides a number of lifecycle interfaces that allow the manager to setup your components. E.g. give access to other components or pass configuration data to them. It also manages concurrent access to a component by instantiating additional ones, pooling instances or sharing instances across thread depending on the marker on the component. Cocoon is based on this principle and whenever you access a generator for example, the Avalon component manager directs the play. If your classes don't have any such requirements, converting a normal class to a component is to a) create a corresponding interface b) add a ROLE constant to the interface as individual name c) declare your component in cocoon.xconf using component-instance/ d) access the component from other components that implement the servicable interface. (your component gets a reference to its managing component manager) e) use manager.lookup(YourInterface.ROLE) to access it f) release the component when done using manager.release(myComponent) d) does not apply for flow e+f) there are methods on the cocoon object in flow for this. Avalon is very easy to program to.

Re: building Collection from JDO problems
Hi Bert:
It looks like a table game :-)
Well you went to the next step and you are faced with the next trivia :-D
AFAIK, the problem is that you need to JDO enhance your classes. See the

NOT jdo 1.00

Re: woody, flow and database confusion
Joerg Heinicke dijo: Hello Bert, it seems we went exactly the same route this week. Great! I think I takes me 1 or 2 months while understanding how to start all this puzzle and choicing between OJB and Hibernate and why + what if I am wrong and this cannot work at all, also waiting for a more functional Woody and Flow, and a couple of additional things, etc.! :-DD In fact, I am glad to see the path being opened in mid 2003 now is clear and other can use and improve the road. This was the main goal of OJB block and I like to see that it is useful to other people. Share the ideas with the community is great! Maybe we should put together our efforts to get this thing working and to help other people with a wiki page. I will love this! I am sad that I cannot had the time to do this. I need to tell I am newbie in OJB too. Maybe 1 or 2 days ahead in some cases, but this is nothing. Of course we are trying to improve our knowledge and will share it. In short, please write the wiki page and I promise to review it and improve it in case I know a little bit more. I will do it very glad. I only don't have that time til beginning of March because there is still an exam to be passed. So let me write a short mail about my experiences. We have at least our own application running with OJB. We can retrieve lists or single objects from the db and display them with Woody, we can store them back and delete them. We only have still a problem with object identity, I think there is an old bug in JDO implementation in OJB related to indetities. We fight with this problem 2 weeks with no results, then we decided to switch to PB implementation. But let the open door to rewrote the code when JDO will be avaliable. so that storing does indeed create a new object in db, but that's another problem we didn't have a closer look yesterday evening. We started also with OJB/JDO and had bad feelings when we saw that we have to maintain at least two files (package.jdo, repository.xml) to get it working. The reason for it is that JDO and OJB are two different products, OJB provides only a plugin for Sun JDO at the moment, but both must get their configuration. Though it's easy to write a stylesheet that converts one format into the other I tried to use only JDO. While writing the code in Druid, I noted that repository.xml has far more info that the .jdo onces. In fact after querying on the OJB maillist I noted we don't need to put too much info inside the .jdo. AFAIK, the only need info in .jdo is the info that currently druid put on the .jdo files. But JDO is just the API, the SPI must be provided by the database vendor and as there are probably not that much for a specific at the moment, you need OJB. Then we found out that the JDO implementation has a performance problem: Retrieving 20 rows out of 6.000 in a db leads to instantiation of all 6.000 objects, they are filtered by JDO. That's not a problem of OJB, it's just how Sun JDO works. So we were back nearly to the beginning. Hmm.. switching between JDO-(PB|OTM|ODMG) is not too painfull. This in one of the best features of OJB at all. We decided to go on with OJB (as it allows easy switch between different persistence frameworks (JDO, ODMG, OTM, PB)), but used the OTM. This one provides also object level transaction. Now the application itself. I don't love the idea of accessing the persistence layer from the flow/controller layer directly. We access it only from the application layer to have obvious tiers. We have a DAOFactory that returns DAOs (e.g. either JDO or OTM), the implementation of the persistence framework access is abstracted. We choosed to have DAO classes with static methods, that way we don't need to create too many DAO objects. Between Flow and DAO classes fly the Beans. Some of them are BeanList. They are easily passed to the cforms using the framework binding. I am not sure if this is the best approach, but it works. I will be glad if we can comment about what are the pros and the cons of Joerg approach vs. this approach. I am not a Java or OO guru. Comments are very welcome. In theory we can switch to Castor, Hibernate or what else without touching the application layer. Can you explain what is the application layer? I am confused here. Is the application layer the view in the MVC paradigm? Each object specific DAO will provide different methods for retrieving, storing, deleting etc. As the layers below the flow layer are no Avalon components and not in relation to Cocoon, but Plain Old Java we kicked out Cocoon OJB block completely and just use OJB. If this was a good decision we will see. I thought to do this too. In fact the first experiment was using directly OJB in Cocoon: http://wiki.cocoondev.org/Wiki.jsp?page=OJBWithJDO Later, I thought that the best approach was to use a common factory for all the servlet instead of using OJB directly. But it won't be that difficult to switch the
Re: Incomplete image requests
Geoff,
yes, the reason I am not using an image/database reader is because of
the hibernate middle layer used in the system and wanting to keep the
system consistent. In terms of whether I am getting back information,
yes I am. If i make a single call for either image then the data is
returned to the browser, if I try and make multiple image requests then
only one image is returned successfully and then the browser sits there
waiting for the next one.
many thanks in advance...

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?

many thanks in advance

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
