unittesting flow
Hi, I was wondering if someone has got a hint on how to unittest flow (javaflow in my case, but I guess it'd be the same for any flow). I searched the wiki and the archives without luck. I saw the callFunction-method in SitemapComponentTestcase which looks like what I want, but couldn't get it to work. I have used SitemapComponentTestcase to unittest generators before, so I think I know what I am doing. I created my .xtest-file, added the flow- interpreters role (copied from cocoon.roles) and added a component- instance for JavaInterpreter. Still I get an exception Could not retrieve interpreter... when I call callFunction with type java. Debugging I find that indeed the interpreter-selector doesn't contain the JavaInterpreter. Am I missing something? It'd be great to get a working example of how to use callFunction or at least a short comment on what the parameters are and what needs to be added to .xtest, just to make sure I am not overlooking something. Or if someone has got a different way of unittesting flow I'd be very happy to hear it. I am going to use flow extensively in my project and I want to make sure I can test it properly. HTTP-testing, as has been suggested before on the list, doesn't go deep enough. Thanks a lot for any help!

Re: ant static generation - class not found DOMError
Hi Martin, thanks for your help. I doesn't work, though, unfortunately. SET ANT_OPTS=-Djava.endorsed.dirs=D:\cocoon-2.1.4-src\cocoon-2.1.4\lib\en dorsed-Xms64m -Xmx512m What is -Xms64m -Xmx512m. I set the ant option as you did, but didn't understand what this second part is. I don't think, though, that it is a problem of the libraries not being found. Cause the missing class org.w3c.dom.DOMError really doesn't seem to exist. I googled for it and could only find it as part of the JDK 1.5 beta API, so I figured it was a fairly new class and I might have to update one of my libraries.

Re: ant static generation - class not found DOMError
Hi Upayavira, thanks for helping. Does it work with the CLI instead of the ant task? No, unfortunately that doesn't work, either. I used the sample xconfig file from http://cocoon.apache.org/2.1/userdocs/offline/configuration.html#Sample+xconf+File with minor changes for my project. I can see the CLI loading all the jars, but as soon as it starts executing, I get the error: Main Class: org.apache.cocoon.Main Exception in thread main java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.jav a:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessor Impl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at Loader.invokeMain(Unknown Source) at Loader.run(Unknown Source) at Loader.main(Unknown Source) Caused by: java.lang.NoClassDefFoundError: org/apache/commons/cli/Options at org.apache.cocoon.Main.setOptions(Main.java:132) at org.apache.cocoon.Main.main(Main.java:255) ... 7 more Before, while loading the jars, it said however, that commons-cli-1.0.jar was added and that one does contain org.apache.commons.cli.Options. So, since CLI didn't work, I tried the ant task, but, as I said, not with any more success. Are you using org.apache.cocoon.CocoonTask? (There's an older one in the scratchpad which I'll remove soon). Yes, I am. I copied the sample ant task from http://cocoon.apache.org/2.1/userdocs/offline/ant.html#Sample+Ant+Task and made some minor modifications for my own project.

Hi, I am trying to use the cocoon ant task to generate a static website. The error I am getting is: NoClassDefFound: org.w3c.dom.DOMError.

again: best practice for minor form changes/optional elements
Hi, I thought I'd give this a second try, since I didn't get any replies the first time round. I'd appreciate any kind of comment/suggestion. Thanks! Just wondering whether anyone has got any thoughts on this/best practices to offer: I have got a woody form that I need to display in very slight variations, e.g. a certain button should only be visible under certain conditions that I can check in my flow. The options I can see are: 1. Have several form templates, one for each variation. Don't like that very much, too much duplication. 2. Send a request parameter to the formpipeline. Assign an extra attribute req-param to the optional elements wt:widget id=optionalbutton filter:req-param=optionalbutton/. Then write a transform that checks for the req-param attribute and filters the corresponding element if no request parameter by that name is given. 3. Use jxtemplate generator to generate the formtemplate and use the context object to pass a value that determines whether to display a certain element or not. Inside the jxtemplate I'd enclose the element in an if-statement. Any thoughts? Thanks a lot Stefan - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
limitation in woody-repeater binding and collections
Hi, here's an issue I came across the other day and it took me quite a while to figure out, so I thought I'd let everyone know and maybe someone could include a note in the WoodyBinding documentation on the wiki: I had a bean with a Collection of type HashSet which I was trying to bind to a Woody Form. Reading it worked perfectly, updating, too. But inserting a couple of new elements at a time caused a problem: The binding seemed to save only some elements and create empty collection elements (no values set) for others. Tracing the problem through the woody code, I realised that the code implies the use of ordered collections such as LinkedList, ArrayList... Woody first creates a new element instance and adds it to the collection. It then obtains it from the collection using jxpath syntax mybean/collection[count] to fill in the values. count is the new number of elements in the collection (after insertion) which assumes that the new element has been added at the end. This is true for Lists, but not for my HashSet. So, in fact, any odd element would be retrieved, possibly the new one and possibly not. That produced an unpredictable behaviour where element values would be overwritten and others left blank. Maybe that could be pointed out more clearly on the wiki page where it only says that the property has to be of type Collection. Might save others some time.

Re: building Collection from JDO problems
Hi Bert, Does the problem with object identities mean that OJB is not the right way to go when building forms that display editable lists? If that is that case I lost quite a lot of time just trying to find an quicker way to build web forms. What are the limitiations of OJB exactly? thought I'd point this out to you, since it cost me a lot of time and I still haven't solved it in a satisfying way. AFAIK, there is a bug in the current OJB release rc5 with the use of javax.jdo.Query (as you use in your retrieve method). The objects in the collection it returns are actually not persistent as they should be. The nasty implication is: You retrieve a collection, you edit it via your form. You call transaction.commit() and the database doesn't get updated! The only way to retrieve a persistent object is by using getObjectByIdentity (or something like that) like they do in the JDO tutorial on the OJB site. They recently fixed the bug (get the latest CVS HEAD and compile it yourself), however, I am still running into a problem: I have got an object of class User that contains a field roles that is a collection of Role objects. When I retrieve a collection of User objects via Query, the respective Role objects are retrieved with them automatically. The users are persistent as they should be (thanks to the bug being fixed), the connected roles however still aren't. So by the time you commit, OJB tries to re-create the roles in the database and you get duplicate key errors. I haven't had the time yet to ask the OJB people about it. This is not to do with your current problems, but I thought I'd point it out to you before you run into it. For the moment, I actually gave up on OJB-JDO after spending a lot of time on it and just use the OJB PersistenceBroker-API which so far works perfectly and reliably for my relatively small persistence needs.

Re: Authentication framework problem
Hi Nesto,
not a complete answer, but some pointers that might help you:
1) writing a simple action that checks the user parameters
(username/password) provided through a web form, with those stored in
the database. Here the problem, for me, is to write java code that
reuse the connection pool set for other pipelines (but at a transform
level). I have no idea...
You need to get hold of the DataSourceSelector to get hold of a pooled
connection:
1.Write an action that extends ServiceableAction.
2.Overwrite the service method:
public void service(ServiceManager manager)
throws ServiceException {
this.dbselector = (ServiceSelector)
manager.lookup(DataSourceComponent.ROLE + Selector);
super.service(manager);
}
[I am assuming dbSelector is a private field of the action of class
...avalon.framework.service.ServiceSelector.]
3. Overwrite the dispose method to release the component:
public void dispose() {
this.manager.release(this.dbselector);
super.dispose();
}
Now you can use the dbselector anywhere in your action code to obtain a
datasource which in turn can give you a connection:
DataSourceComponent datasource =
(DataSourceComponent)this.dbselector.select(nameofyourpool);
Connection conn = datasource.getConnection();
conn is of class java.sql.Connection, so from here you should be able to
get on yourself using JDBC.
NOTE: I am still not very experienced with avalon and components, so the
code might not be ideal, but it works for me. If someone has corrections,
I'd be happy to hear them.
For a good example of obtaining a pooled connection and using it, look at
the SQLTransformer.
2) customize the authentication resource, to use the existing
authentication framework. But Where can I add the custom code that
queries my database? Do I Have to change only the AuthAction class?
I don't know the authentication-framework particularly well, but the
authentication handler takes a uri that has to return some xml to grant
authorization or not, doesn't it? You could just write an esql-xsp-page
to query your database and return the xml accordingly. That would
probably be a lot easier than the action-approach, if you're already
using the framework.

Re: role-based access to pages and parts of pages - ideas?
Nicolas, I'm interested: I've done the same work but with an XSL Stylesheet but a java class would be better. Where can we get it? I've sent you a copy of my classes off-list. It is, however, as I pointed out before, tailored to my own little authentication system, not to cocoon's framework. Since the transformer is very simple, it should be very easy to adapt, though, given some knowledge of the cocoon framework (which I don't have enough of). To make you understand the code, here's a quick outline of my system: Just like cocoon's authorization handlers, it uses an Avalon component Authorizer that does the actual checking of permissions of a user that is logged in (I sent you this class to make you understand better). This component is used by the transformer and by an AuthorizerAction. User information is - again, just like in cocoon's framework - stored in a session context. Creation of this context is done by an AuthenticationAction that checks the identity of a user (again, I've included the class). Hope you can make something out of it. Feel free to ask questions.

Re: role-based access to pages and parts of pages - ideas?
Helma,
Any ideas?
might not be of much use for you, cause I am not using the
authentication-fw, but I thought, I'd tell you anyway. I am using a
structure very much like the authentication-fw, but using my own actions,
thus a lot lighter and tailored exactly to my needs (thus not as nice and
flexible as the framework).
There are actions for logging in, logging out, authenticating and
protecting, just like the framework.My sitemap looks very much like
the one in the authentication-example without flow (thus not the one you
adopted).
Unlike the framework, my protecting action takes a parameter role and
it checks whether the user who is locked in has that role. If so, access
is granted. so something like:
map:match pattern=protected
map:act type=authorize
map:parameter name=role value=admin
page-generation.../
/map:act
/map:match
That way, I keep everything in the sitemap and my actions. Also, I could
do authorization depending on the url and the user who is logged in,
e.g.:
map:match pattern=protected/*
map:act type=authorize
map:parameter name=role value={1}
page-generation.../
/map:act
/map:match
Here everything in protected/admin could only be accessed by users with
role admin.
HTH. Maybe you can derive an idea for your problem from this. I am also
happy to share the code, if you want to have a look.

Re: Reading and passing parameters in the sitemap

have the following problem: I would like to pass the parameter

Use input modules. The RequestParameterModule lets you do exactly that.
Just put {request-param:gr_name} into the redirect-uri.
(Also see http://wiki.cocoondev.org/Wiki.jsp?page=InputModules)
Furthermore - I would like to pass the path of the saved
file there, are there any possibilities to do this?
Would the pass not simply be
e:/cocoon-2.1.2/build/webapp/LetterMan/grafiken/{1}/ as you as
parameter to the action? Or maybe
e:/cocoon-2.1.2/build/webapp/LetterMan/grafiken/{1}/{request-param:gr_n
ame} if you want the path+filename. If not, get back to me.

Re: Actions and Session
Giancarlo,
the SessionModule that you access by {session:...} only provides general info about
the session like session-id etc. You need to use the SessionAttributeModule to access
attributes. like your username. Use {session-attr:username} instead (if you haven't
changed the module name to something else than session-attr in your cocoon.xconf
which I suppose you haven't)

Re: tutorial - MySQL - NoValidConnectionException: No valid JdbcConnection class available
Flavio, if you have tried all the reasonable things and doublechecked your settings (which I think you have from previous posts on this thread), it's most likely to be a version problem. I ran into the same problem when I upgraded from MySQL 4.0 to 4.1 and had to replace my old mysql-jdbc-connector by version 3.08. What helped me was getting the (by then) most recent version 1.1.1 of the excalibur datasource-jar from their website and replacing the old one in the WEB-INF/lib folder. Also, there are (or at least there used to be) two versions of cocoon-2.0.4, one for JVM 1.2,1.3 and one for JVM 1.4. The excalibur datasource component is different in the two. Since you are using the binary version, have you doublechecked you got the right one? For reference, my system: tomcat 4.1 jdk 1.3 mysql 4.1 mysql-jdbc-connector 3.0.8 excalibur datasource 1.1.1 Hope this is of any help.

Re: possible to put identifier in cocoon list subject?
Steven, thanks for replying. First of all, I made a little mistake in my previous post. Of course, it allows to filter by sender addresses (that doesn't help, though, since there are many, many senders on the cocoon list), but it doesn't allow to filter by recipient. Apart from sender, I can filter by cc and subject. That's all. So unfortunately your suggestion won't work either. It's server-side, though, so maybe I should just do like you and use a client-side tool.

Re: Actions and Session
This way a can get session attributes either as parameter passed from sitemap,
or with Session object in an Action. Am i right?
Not sure whether I got you right: You mean, assign {session-attr:username} to an
action parameter and then use the parameter in the action?
This seems to me an overly complicated way of doing this. Simply accessing the session
object in the action, as you suggest as well, seems a lot more reasonable.
