How to register flowscripts dynamically at runtime?
Hello, we need the possibility for our customer to put all essential configurations of our system together in one file (outside the sitemap and the xconf). This includes the configuration of all special flowscripts in this file, too. To do so, we need to (re-)load these flowscripts at runtime. Now my question: Is there a Cocoon component available which I can use to register new flowscripts at runtime and what points I have to keep in mind to do that? Any hint is appreciated. Thank you a lot! Regards Stephan

[BUG?] JavaFlow and getComponent
Hello,
it's possible that I have found another bug in Cocoon. Using
getComponent within a JavaFlow causes a cryptical exception. I wrote an
example using Cocoon 2.1.6 which doesn't work. Can someone please verify
whether it is really a bug or just a mistake of mine?

Re: [vote] splitting cocoon.xconf
Sylvain Wallez wrote: Team, here's a formal vote about splitting cocoon.xconf. I propose to add a new feature in cocoon.xconf so that adding/removing blocks to a Cocoon instance doesn't require do merge each block's configuration in a unique cocoon.xconf file as of today. With this feature, cocoon.xconf can simply be a list of imports, thus allowing to very easily add/remove blocks in a Cocoon application. For more background, please see the initial "splitting cocoon.xconf" post [1]. The first implementation will focus on basic import (one file per element), and later on we'll implement globbing features proposed by Carsten [2]. Please cast your votes. Here's my +1 (of course!) Sylvain [1] http://marc.theaimsgroup.com/?l=xml-cocoon-dev&m=110354180900487&w=2 [2] http://marc.theaimsgroup.com/?l=xml-cocoon-dev&m=110361460811792&w=2 If I'm allowed to vote here: +1000 ! Really good idea! One suggestion: Why not optionally scanning the folder WEB-INF for files having a special suffix (e.g. *.inc.xconf) and then, including the content of this files under the root element in cocoon.xconf? This avoids any changes of cocoon.xconf if own components must be included. Just placing such a file in WEB-INF makes the component or block working. This makes it very easy to provide own components for customers by using build processes like Ant. Maybe two possibilities: An import element to import a special file and a element to scan a certain folder for files to include at the specified position. An example: WDYT? Ahh, after reading the messages of the posted links above, I saw, Carsten has already posted an similar idea. Nevertheless, I will post this message, too ;-) Just to express that this feature would very very nice!! Regards Stephan
Re: [CForms] How to iterate other a model?
Hi, after I had tried several times to iterate over a widget using flowscript (model.lookupWidget()) I had realized that - in my opinion - this is not easily possible. The problem: I don't know the id's of the widgets! So there are two big questions I'm having: 1) In Java I can use .getChilds() of a ContainerWidget which returns me an iterator to iterate over all childs of an widget. I couldn't find such a method in the flowscript API. How to solve this problem? Either I need a length of all childs and then I can get one by one by pointing to its index or I need an iterator. 2.) I didn't find a way to resolve a Widget value of type MultiValueField. Therefore its not possible to retrieve such values. None of "typeof" or "instanceof" worked correctly to determine the object type. How can I resolve whether it is a MultiValueField or not? Thanks! Regards Stephan

Yes, you can use lookupWidget() that accepts a path-like syntax (i.e.
"a/b/c" or "../d")
Another question: Is there an API doc available for this object?

Hi Sylvain,
that's why I'am a little bit confused about the documentation because
model.lookupWidget("age") as well as other methods from type Widget
doesn't work in my flowscript. I got this exception:

var form = new Form("cocoon:/formDefinition/" + inquiryName);
form.showForm("formTemplate/" + inquiryName);
var model = form.getModel();
print("Widget: :" + model.lookupWidget("age"));
What's wrong here?

Hi Torsten, I guess he is after JAVAflow ;-) Yes.You're right! ;-) IIRC the parameters are set inside the continuation context.

Re: SQLTransformer, reaction on socket close?
Hi Sylvain, One output format will be a raw xml document (generated by the SQLTransformer). It will be parsed by an java client. On the other hand the output will be transformed to a HTML or Excel document by an XSLT Transformer. As you has written in your post before, I think the second one is not possible to detect a "browser cancel"? Is there a workaraound available? What happens on the first one (directly xml output) if the user stops the transfer by closing the browser? Thank you, Sylvain. Regards Stephan Sylvain Wallez wrote: Stephan Coboos wrote: I had forgotten to say: "The database connection should be closed if the user closes the browser _during reading_." So a hughe set of data which are not needed should not read again out of the database to save resources. We can know if the user closed her browser only by receiving an excption when trying to send data. That means that output of the SQLTransformer must be streamed down to the browser with no intermediate buffering, which unfortunately is what happens with an XSL transformation. What are the components after the SQLTransformer? Sylvain

Wizard using CForms doesn't work?
Hello,
I need to implement a wizard using CForms. For this I had created one
form definition which contains all fields of all wizards. Within the
flowscript I only create one form instance for all shows. Each wizard
form will contain a subset of fields of the form definition. At the end
of the wizard trip I want to get all datas into one model. My flowscript
looks something like this:
function foo {
var form = new Form("form.xml");
form.showForm("wizardStep1");
// Do something here
form.showForm("wizardStep2");
var model = form.getModel();
// Do something with model here
// Send ok page
cocoon.sendPageAndWait("ok.html");
}
But this doesn't work. The first wizard will be shown and the second
one, too. But after filling out and sending the second form cocoon will
allways display the second wizard and not go to the ok.html page. Isn't
it possible to make several calls of showForm on one instance? Whats
wrong here? Is this a known problem?
Here you can see the second template. It should be correctly because no
error was thrown:
http://apache.org/cocoon/forms/1.0#template";
xmlns:fi="http://apache.org/cocoon/forms/1.0#instance";>

Hallo, I would like to know whether Cocoon stops creating the output stream if the user canceles the response. For example I have a SQLTransformer sheet and in it SQL statements which can take a long time of execution. So, what I'd like to know is whether the user canceles the response is the sql stream (db connection) canceled, too? Or finishes the SQLTransformer the output (ResultSet) from the database first? It would be nice if the user can canceles the response (database query) if it takes too long and then no background process will be longer executed. Thank you. Regards Stephan

If I'am trying to start such an example the following error message will be thrown: Caused by: org.apache.avalon.framework.component.ComponentException: Could not find component (key [org.apache.cocoon.forms.FormManager]) at org.apache.avalon.excalibur.component.ExcaliburComponentManager.lookup(ExcaliburComponentManager.java:263) But the forms block exists and the necessary libs (the class FormManager), too. What can I do? Is it fixed in the nightly build? Or is it a problem on my side? Thank you! Regards Stephan
Filter like in servlet container
Hello, why not implement a filter system like in a servlet container exists to filter the request and the response? Because using the filter of the servlet-container there is a bindig between cocoon and the servlet container necessary. This filter technique would be useful eg for closing transactions after view generation (like hibernate and some others) or to simply plug-in a login mechanism (just a few examples out of many). What do you think about it? Regards Stephan
Re: component lifecycles
Jeremy Quinn wrote:
How would I organise this differently, in the situation where I had
several of these Components, each differently configured, that I
wanted to be able to load in FlowScript in a similar way. Maybe we
want one setup for read-only privs and another setup for read-write
privs etc.
Use the ServiceSelector like for DataSources. I dont't know where
documentation about this can be found, but the sources of Cocoon should
contain many lines of that kind and a search on "ServiceSelector" should
help.
Using a ServiceSelector, a entry in cocoon.xconf looks like:
In a java class the code to retrieve the component foo1 should be
something like:
ServiceSelector selector =
(ServiceSelector)this.serviceManager.lookup(Foo.ROLE);
...
Foo foo1 = (Foo)selector.select("foo1");
...
Hope this few lines helps.

Re: Best practice for database access in flow layer
Adam Ratcliffe wrote:
I'm looking for a little direction on the most appropriate way to access
a database from the flow layer.
My application requires read-only access to the database only so an O/R
type approach would probably be
overkill.
What I would like to do in the flow layer is something like the
following psuedo code. Do a select query
against the database using a java component. Test the returned
collection to see if it contains any
elements and use that test to determine whether redisplay the current
page or to break out of the
recursive loop.
Any suggestions?
function searchCategories(locType, class1, class2) {
var categories = Search.searchCategories(locType, class1, class2);
if(categories != null) {
// if search returned categories, search again on expanded
categories
cocoon.sendPageAndWait("page/showCategories.xml", {"categories" :
categories} );
// when user request arrives
class1 = cocoon.request.getParameter("class1");
class2 = cocoon.request.getParameter("class2");
// recursively calls itself with
searchCategories(locType, class1, class2);
}
}
Create your own avalon database component. So you can switch the
persistence layer like you want. Please have a look at the following
link. (It's in german language but the code should help you. Use class
"AbstractManagerDB")

Flow and and its own scope
Hello, why having bizData objects its own flow scope and not be stored e.g. in session or request? Is it possible to retrieve the object via session or request without using extra setAttribute in flow? Thank you. Regards

I will see to report this bug to the xalan group. As a workaround, you can include a transformer in your pipeline that throws away all events between the start and end of the doctype. For example, inserting an identity XSLT transform will do this (though not in the most optimal way). Did you have an example how to do that? Thank you. Regards Stephan

Problem using JavaFlow and exceptions
Hello,
I'am sorry but I have another problem using JavaFlow. I want to use my
own Exceptions in JavaFlow. One Exception contains a long type as
parameter. But if so, the flows will not load at startup. Please have a
look into my source code example:
package foo.bar;
import org.apache.cocoon.components.flow.java.AbstractContinuable;
public class TestFlow extends AbstractContinuable {
public void doTest() throws Exception {
while(true) {
this.sendPageAndWait("test.jxt");
throw new FooException("test", 123);
}
}
}
The class FooException:
package foo.bar;
public class FooException extends java.lang.Exception {
private long id = 0;
public FooException() {
}
public FooException(String msg) {
super(msg);
}
public FooException(String msg, long id) {
...
this.id = id;
}
}
If I use the parameter id, at first call of the corresponding url I got
the following error output into the logs of tomcat and flows will not work:
java.lang.VerifyError: (class: foo/bar/TestFlow, method: doTest
signature: ()V) Attempt to split long or double on the stack

Another bug in javaflow?
Hello,
please have a look at the following java flow code:
...
public class TestFlow extends AbstractContinuable{
private boolean foo= false;
public void doTest() throws Exception {
while(true) {
this.getLogger().debug("reload = " + this.foo);
this.sendPageAndWait("test.jxt");
this.foo= true;
}
}
}
I assume if I'am "hopping" from continuation to continuation the
variable "foo" should always be "true". It's ok it is always "true".
BUT: If I reload the page in my browser (hard reload) the var "foo" is
"true", too. There is no initialization process! So "foo" is always
"true" in the same browser instance. In my opinion, If I make a reload
without a call of a continuation the var reload should be false, should it?
Is it another bug in javaflow?
Thank you for your help.

Stephan
Taglib-Block doesn't work? (Deprecated?)
Hello,
I had tried to write my own taglib using the TagTransformer but it
doesn't work. I can't find some informations about it, so I had copied
the example and changed something but it doesn't work. I want to use a
tag to print out "HELLO WORLD". My changes in detail:
1.) I had written my own class HelloWorldTag:
package foo.bar.taglib;
import org.apache.cocoon.taglib.XMLProducerTagSupport;
import org.xml.sax.SAXException;
import org.xml.sax.Attributes;
public class HelloWorldTag extends XMLProducerTagSupport {
public int doStartTag(String namespaceURI, String localName, String
qName, Attributes atts)
throws SAXException {
String hello = "HELLO WORLD";
this.xmlConsumer.characters(hello.toCharArray(), 0,
hello.length());
this.getLogger().error("T E X T = " + hello);
return this.EVAL_BODY;
}
}
2.) I had created a subproject tagtest containing a xml file tagtest.xml:
3.) My sitemap looks as follow:
http://apache.org/cocoon/sitemap/1.0";>
tag
3.) In cocoon.xconf I had registered the tag :
4.) After calling http://localhost:8080/cocoon/tagtest the tag
will not be replaces by "HELLO WORLD". I got the following output -
nothing parsed:
What is wrong here? Thank you for your help.
PS: I had tried the taglib block it seems it doesn't work, too! Whats
about this block? Is it deprecated?

Stephan

Hello,
I have a problem using Objects in JavaFlow before a while loop. Please
see my first posting [JavaFlow] java.lang.VerifyException. In my opinion
it can be a bug in the JavaFlow block.
Because my fist posting was not so clear, I had tried to reproduce the
error for a while and I had discovered the following code which creates
such an error (you need the packages of Lucene):
java.lang.VerifyError: (class: foo/bar/TestFlow, method: doTest
signature: ()V) Incompatible object argument for function call
Is it really a bug? Why is it not possible to declare these three line
within the method doTest? What can I do?
Yes, it seems to be a bug. I guess its a problem the following line
query = QueryParser.parse("foo", "bar", new StandardAnalyzer());
I had many problem in the past with uninitialized objects and saving the
continuation. I will take a look into it.
It was a problem with null objects, which were stored into the
continuation. If the frame will be restored, the null object cannot
be casted into the right type. So, at the end the correct signatur
couldn't be found.
Hits hits;
IndexSearcher searcher = null;
sendPageAndWait("foo");
hits = searcher.search(query);
I have fixed it now.

Wow, what a quick work!
Thank you very much!

There was hard discusion. You can search cocoon-dev mailarchives about this topic. Yes.

Re: Flowscript and return to pipeline
Ralph Goers wrote: I don't mean to start any kind of flame war here and the following is strictly my opinion. Actually the statement below is the exact reason I and my colleagues are reticent to use flowscript. I have no problem with using flowscript to manage a couple of pages that are linked together (i.e. - a form to fill out followed by a confirmation page). But using it for more than this violates the separation of concerns principal that Cocoon strives to achieve through the sitemap. It is far too easy to start throwing all your business as well as presentation logic into flowscript and soon you'll end up with something worse than JSPs. This is impossible to do with just the sitemap. Frankly, I have been concerned with how so much effort seems to be focused on moving Cocoon from its sitemap roots to flowscript. Yes, I agree with you but why not using a solution which markes a flowscript as "linear" or "returnable"? If this flag was setted it should be impossible to use sendPage and sendPageAndWait, ... within the flowscript. So it is not possible to call another pipeline and the flow must return to the called position in the pipeline. With this solution you have a kind of action which is much more easier to develope. 1.) If you read the sitemap you can decide (by reading the sitemap! not the flowscript!) which returns after work at the same position. 2.) The programmer of a flowscript is not able to use sendPage,... and therefore he has to design the flowscript to fit this need. What do you think about this? Regards
Re: Flowscript and return to pipeline
Christopher Oliver wrote: Um, how much harder is this: Yes we had tried this solution, too. But we have much more flowscripts than only readProductBeans and for each one we have to split our pipeline. Therefore the sitemap will become a unreadable size. The other point is, if you (as designer or htmler) dont know, what function readProductBeans does you cant decide which pipeline will be called next. In you example, it is easy. In real projects it is possible to become a terrible find action. It would be more understanding for the html-designer if you can say: Here are your templates and with this call you can get all your data you need. Do it. We want to creat a more generic way in which the html-designer is able to plug-in his on pipelines. No we are doing something like this and I think this is not the best solution: Regards
Flowscript and return to pipeline
Hello, in some discussions I'd heard that actions and XSP should be more and more replaced by flowscript. I think, this is a good idea because flowscript is a good way to integrate logic parts into an application. But with one thing I cant agree. Why shouldn't it be possible to return to the sitemap without sendPage? I had read some discussions about the decision, throwing a Exception if no sendPage existst within a flowscript but I think this decision was wrong. In our current project we have to create some Beans from a Database. After that, this beans should be integrated into the actual pipeline, but this is not possible because a return after the flowscript is not possible so we have to use Actions instead b This is not possible but would be very very nice: Instead we have to do a work arround with an action which every time returns null and to put the Beans into the request scope. So we have to merge actions and flowscripts in one application but we do not want to use actions... So what to do? An alternative way would be a kind of "linear"-flowscript which is not able to redirect into another pipeline. What do you think about this? This could be marked in the pipeline with an attribute linear="true" for example: So if you read this line, you can be shure that this flowscript comes back and does not redirect into another pipeline. Thank you. Regards
cocoon.request.getAttributeNames not implementend yet?
Hello,
in the cocoon docs
http://cocoon.apache.org/2.1/userdocs/flow/api.html#Request+Object
I can read that cocoon.request.getAttributeNames should return an object
of type java.util.Enumeration but this function seems to be not
implemented yet because a call of this funtion cases a "Function not
found " exception.
A further look into the apidocs shows me, that the according FOM_Method
doesnt exist:
http://cocoon.apache.org/2.1/apidocs/org/apache/cocoon/components/flow/javascript/fom/AO_FOM_Cocoon.FOM_Request.html
After I had looked into the source it seems to me adding this method is
very simple by adding the following lines to AO_FOM_Cocoon.FOM_Request:
public Enumeration jsFunction_getAttributeNames() {
return request.getAttributeNames();
}
Thank you.

So I only work with flowscripts and avalon components but very seldom with actions or xsp. I think, the concept flowscript + avalon component is the future way to integrate logic into a cocoon app. But in my opnion there are a bunsh of disadvantages creating avalon-components in cocoon: 1.) Why it is necessary to extract the cocoon.roles from the cocoon.jar to register the components? It is not necesssary. You can either make your own roles.file and indicate that in cocoon.xconf like: or just use the full component descriptor as you'll find some in that form in the cocoon.xconf: Oh, fine. I didn't knew about this. For me at the first time I had done this, it has looked like a change on the whole cocoon archticture and not a simple integration of a logic component. I think its not clear why do so. It looks like this is not the suggested way to intregate business logic. But it is, isn't it? My suggestion: The cocoon.roles should be situated in the classes folder, not in the cocoon.jar or better in WEB-INF beside the cocoon.xconf aso. No. the cocoon.roles file is a private one for cocoon only. If you are in need of your own write as mentioned above. 2.) Its very hard to create independent components for customers. What I mean is: Using a component in flowscript is relativley simple (the customer is able to use this;-) but creating a component can be very hard and complex. So it's possible that a new market place grows up in which avalon-components for cocoon will be created and distributed (Mailer-Component, DB-Component, aso.). But moving a component from one cocoon-app to another cocoon-app can be very hard, too (4 steps and more for moving are to much). So it should not be necessary to register all roles in the same roles.cocoon and configure it in the same cocoon.xconf. In my opinion the best way would be to distribute a new component as jar which has its on "cocoon.roles" and "cocoon.xconf" in it. Cocoon should "mount" these config files at startup. The disatvantage of this order is, that the "real" config files are separated from the one in the components jar. But cocoon should look at startup into the real cocoon.roles and cocoon.xconf. Is the role already registered and configured there, this configurations will be used. Otherwise the configurations from the jar will be used. Have you read about the Blocks comming with version 2.2 (http://wiki.cocoondev.org/Wiki.jsp?page=Blocks)? No I'am sorry. But now I had read some parts of it. It looks really good and seems to solve my problem in future. PS: Is there a timeline avaibale when 2.2 wille be approx released? In 2004? Thank you. Stephan
[Suggestion] Making components easier to distribute
Hello, I like the concept of own avalon components in cocoon very very well. So I only work with flowscripts and avalon components but very seldom with actions or xsp. I think, the concept flowscript + avalon component is the future way to integrate logic into a cocoon app. But in my opnion there are a bunsh of disadvantages creating avalon-components in cocoon: 1.) Why it is necessary to extract the cocoon.roles from the cocoon.jar to register the components? For me at the first time I had done this, it has looked like a change on the whole cocoon archticture and not a simple integration of a logic component. I think its not clear why do so. It looks like this is not the suggested way to intregate business logic. But it is, isn't it? My suggestion: The cocoon.roles should be situated in the classes folder, not in the cocoon.jar or better in WEB-INF beside the cocoon.xconf aso. 2.) Its very hard to create independent components for customers. What I mean is: Using a component in flowscript is relativley simple (the customer is able to use this;-) but creating a component can be very hard and complex. So it's possible that a new market place grows up in which avalon-components for cocoon will be created and distributed (Mailer-Component, DB-Component, aso.).

How do I activate passing request parameters thru resources to a flowscript? Can you explain why you would need to do this? The example you've given above is pointless AFAICS. Geoff Hello Geoff, yes, I can explain it for you. I'm writing a simple cms. In this cms it is possible to surf arround the entire websites and when the customer wants to edit a page he has to click the edit button situated on top on the page if he is logged in. The whole cms is organized by only one central flowscript which checks for login, recievies the values from the database via components and makes other things. The status of the flowscript must be valid during the user is logged. So I have written two simple actions: The first sets the actual continuation id to the session and the second one extracts the continuation id from the session. At this way, no need is necessary to change the url's on the webpage to forward the continuation id. But to call the two actions I need to call resource every time before the flowscript is called and before the response is sent to the client: ... ... All works fine! Only the request returns everytime null when I'm calling the function "cms" this way. If I call the function directly in the match block, the request works and returns the correkt values!

Re: Moving error-handlers to map:pipelines?

Moving error-handlers to map:pipelines?
Hello, why not place the element of the main sitemap into ? Now it is situated in . Therefore it is not possible to define own error pipelines in a sub-sitemap, because the "main-error-handler" is the first matching handler in all cases. Regards Stephan
Making a reader cacheble?
Hello cocoon experts, what are the differences between making a reader or another sitemap component like transformer aso. cacheable? I've seen that both type of components implementing the CacheableProcessingComponent interface. For what is the method getLastModified on a reader necessary? Thank you. Regards Stephan
CIncludeTransformer now with sitemap params?
Hello,
because I needed a CIncludeTransformer which is able to include dynamically
resources, I had modificated the CIncludeTransformer a little bit. Now its
possible to pass sitemap parameters to the transformer. Within the src
attribute the variable will be replaced by the value of the parameter. Does
anyone need this feature, too?
For example:
somefile.xml:
<...:include src="cocoon:/{filename}"/>
pipeline:
...
...
Result:
<...:include src="cocoon:/myFile.xml"/>
Regards
Stephan

In Servlet programming, too. Here, a string array would returned. Here is a snipplet from the J2EE javadoc: Returns: an immutable java.util.Map containing parameter names as keys and parameter values as map values. The keys in the parameter map are of type String. The values in the parameter map are of type String array. It would be possible and standarized ;-)) Thank you. Regards Stephan
[suggestion] Method getParameterMap in Request?
Hello, in my opnion it would be nice to have a method like getParameterMap() from Servlet programming which returns all request parameters as name value pairs in a hash map. This method should reside in interface org.cocoon.apache.environment.Request oder http.HttpRequest. Do you agree with me? Thank you. Regards Stephan
