Re: portal engine on Cocoon 2.1.3

I'm looking at the (new) portal engine of cocoon and I have some questions about it: It is possible to make any coplet fullscreen, which is great, but how exactly do you know whether you are in full screen mode or not (when you are creating the coplet)? It would be great to know this, because it IIRC this is handled by the renderers. The rederer gets this information because the layout object carries this information. The layout in turn is modified by some component (DefaultChangeAspectDataEventSubscriber) that is subscribed to the appropriate portal event (ChangeAspectDataEvent). If your coplet would be subscribed to the same event, it would be informed of this change. It would be great to have a coplet with some data that depends on request parameters. The request parameters are now read by all the coplets (correct me if I'm wrong). Is it possible to make sure that request All request parameters are made available to all coplets. parameters are only processed by one coplet instance? Maybe I can illustrate this with an example: If you have a coplet that list all users and you want a filter option (selection list) to view only the administrators you have to use a request parameter. This parameter is also read by the other coplet instances. Now, If you want also an instance of the same coplet in the same portal view, but with only the 'guest users' listed, you have a problem, I assume? Or is there any way to avoid this? Those coplets would need to talk to each other through the portal event mechanism. It do not that that the coplets are meant to list only administrators or guests. Both instances should be able to show them both! HTH Chris. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

It's not really "old" vs "new" -- it would be an additional tag that would expand to the very same code as the current combination. Hence, it could be fully combined with all other esql tags that may appear inside a esql:row-results. Well, that would be the plan. Unless you can mix the old and new code together, though, this represents yet another choice between simplicity and power, of which there are several already :-) Indeed. But maybe the current ESQL usage is a little too complex to just list the contents of a table? To be honest, I don't have a problem with embedding SQL SELECTs directly into the XSP or logicsheet. The row-results logic, once grasped, is also straightforward enough. More of an issue is the insert/update/delete logic. In your GT2003 slides, IIUC, you recommended against doing these using ESQL or SQLTransformer: this is my instinct also, but what are your reasons? And could these problems be overcome by an alternate "simple ESQL" interface? If so, that would to me make a more compelling reason for an "ESQL Simple" interface. Nope. What I don't like about manipulating tables from XSP is that a) application logic appears on the page b) different results (eg errors) lead to different pages or ask for redirects which makes the pages too complex to maintain. Actions are a good step in the right direction if used correctly. Honestly, the flow + o/r apprach is so much more elegant for complex logic. Especially if you add CocoonForms aka Woody to it.

For example, you might want to use it only on updates from a specific form. This corrolates to the others-mode attribute for tables in tablesets. Since you most likely will use this mode for every operation, you need to add type="all" to the mode: authentication/authentication/ID 2). Is it possible to pass values as parameters to the action directly from sitemap. No, because input modules don't have access to parameters passed to the action.

The info must first be validated using "org.apache.cocoon.acting.FormValidatorAction". Looking at the sitemap log for the logger "sitemap.action.validator" I find a number of messages where it is validating the info from the forms. After this, there is a message: "All form params validated. An error occurred." There will be a message in the sitemap.log indicating the validation error. In addition, the info is available as request attribute (so dump all request attributes on your page and you'll see).

This last ability has been removed from flow. One can call actions like any other component from flow, but considering the required setup to fulfill the parameters needed for the act() method (The sitemap for this example also seems very verbose; considering just one table or two tables are being handled; can this approach not be 'generalized' further so that it can easily scale up to handle a more complex database - on the order of 20-60 tables) The key would be to use e.g. request parameters to select the right table-set and validation-set. However, this approach does not scale to complex transactions. I assume that checking could (should?) be done with woody form - is there any single sample (even for one database table) that: Adding cocoon forms aka woody and flow to the picture would also suggest to use eg OJB or Hibernate for a persistence layer. There's a OJB block in the distribution which illustrates the basic usage. To use the mod-db actions (which is possible) would require to use some JXPath enabled input module that can access the form model. I believe there's no ready made one, but creating one should be quite simple. However, if there's (almost) no business logic involved and syntactic validation of single values that can be done eg with regular expressions, you might look into the simple form transformer and accompanying simple form instance transformer plus form validator action.

otherwise they could be written eg to session attributes or whatever).
So, I have managed to create a pipeline and descriptor file for the

descriptor for the select action.
This is to chose different (input) modules for reading the attributes'
values. For the select action, only key attributes are considered and
only one mode type ("others") is used. However, a different mode type
could be requested by adding the others-mode="foo" attribute to the
table tag inside a table-set. The above requests a mode type "foo".
This way the same structure description can be used for different inputs.
What are the acceptable values, or where can I find them?
Any value is acceptable as long as it is requested. Otherwise it is just
ignored.

You might need a second view to the same table by defining it twice in your descriptor with a different alias and different key set. Eg usually one would access the user table through the username. For authentication, username _and_ password are required. And if you would like to not store clean passwords, you can easily add the DigestMetaModule and thus store and compare only SH-1 hashes Put another way, for the username and password provided by the user through a login form, can I select a third value from the database, perhaps through a nested block for the DatabaseSelectAction within the block for the DatabaseAuthenticatorAction? Sure, you can. Not really necessary since you can list additional columns to retrieve by the authenticator action.

To access this information, you could either use XSP (request
logicsheet, input logicsheet) or pass the information from the sitemap
to a sitemap component and obtain it with the request input module
"{request:servletPath}/{request:sitemapURI}".
"{request:requestURI}" could do it as well. Anyway, in both cases you
still need to remove some parts of the URI.
You could use XSLT to add this to all URIs, or you could use the
LinkRewritingTransformer for this.

Sorry, slight misspelling: http://cocoon.apache.org/2.1/apidocs/org/apache/cocoon/transformation/LinkRewriterTransformer.html OK, there are two problems. One is to make all links relative to some application root and the second is to compute this application root.

However, this is much harder to solve because while the servlet path is available as well as the request URL or the sitemap URL, your application root is a fuzzy concept not known to cocoon. So, you need to compute this from the data given or configure it. For the full URL you need the servlet path + some path into cocoon. Server name and port are optional but could even be read from the request if so desired. This leaves "some path into cocoon". Best is to configure that (doesn't change anyway).

Wherever the module is declared or used and may have a nested

However, you should seriously consider to use a persistence layer like OJB or Hibernate. The database actions are really very similar but less powerful.

Hmm. Could you give a more detailed example of how this would look like with
either flow or actions? I do have some Java classes now that do the actual
database connection, which I now call from my XSP page. So it would be very
helpful if you could write down a (set of) sitemap pattern(s) with a round
trip (i.e. put query into "DatabaseConnection", put result through Woody on
screen, put result back into "DatabaseConnection").
Well, I can't really help on the Woody part.
For an action, tha pattern is
match pattern="use case 1"
act type="guard that conditions are satisfied"
act type="do something with connection"
call resource="display results handed down from action through
eg. request attributes"
/act
call resource="display error message for connection"
/act
call resource="display error message for conditions"
/match
For flow, the pattern is:
function useCase1() {
userDate = new UserData();
do {
send_start_page_and_optional_condition_errors(userData);
userData = read_parameters_back();
done = check_conditions(userData);
} while (!done);
if (do_something_with_connection(userData)) {
send_query_result_page();
} else {
send_connection_error_page();
}
}
If the logic is contained in avalon components, you'd need to obtain
them first (AFAIR cocoon.newInstance(MYCOMPONENT.ROLE)) and release them
afterwards. Remember to release components before creating a
continuation, though.
I don't like the idea of handling _everything_ in flow (like the petstore
example), which would make me look in two places (flow and sitemap) to find
out what's going on. I do use flow with Woody, but then I prefer to use and
reuse generic functions where all the variables (which
template/binding/definition and where to redirect to) are passed in as
parameters from the sitemap. I guess that I prefer flow to actions because
it's easier to debug and modify.
The key is to use flow _only_ to call your business logic (which is in
avalon components) in correct order and react to exceptions (error
conditions, user faults).
Personally, I would try to avoid redirects where possible and hide a
complete use case (or user story) under a single URL.

You should release components before a continuation is created,
otherwise you risk a memory leak. There have been discussions on

of complexity.
A continuation is always created when sendPageAndWait is called, in
addition, you may create continuation explicitly.

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 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.

Re: MORE: [ESQL] esql:more-results seems broke with Oracle

Hi All
I have been looking into the issue of EQSL paging no longer working with
Oracle since upgrading Cocoon from 2.0.3 to 2.1.4 and although I can't

if I use jdbc as the limit clause instead of our default setting of auto
the paging seems to work again and the is output.
Can anyone (hopefully Chris) expand on this issue and advise on any
further suggestions on how to fix this as I would prefer not to have to
visit all our XSP's and change the limit clause setting to be JDBC as we
plan on supporting more than just Oracle sometime in the future.
I believe the problem is burried in the code that tries to determine the
number of rows in the result set. JDBC2 does not allow to ask the result
set the size. Most database management systems don't know the exact
result set size before having delivered all rows. One way is to use a
scrollable result set and try to position the cursor at a position that
would require another result page ("more-results"). Another is to use
another query, that just returns the number of resulting rows.
IMHO both solutions suck from a performance POV.
OTOH, paging through results makes most sense with ordered results, so
the DBMS would need to have retrieved all rows anyway, so additional
costs could be transfer over the network if the select is not limited or
locks preventing concurrent queries / additional overhead to maintain
the scrollable resultset.
Retrieving just one row too many is fine but you'll know only at the end
that there's still more data to be displayed -- thus you couldn't put
the "more" button at the top of the page unless you're using eg XSLT
to move the button up. You probably wouldn't want this for large results :-)
Back to your question: You'll need to look at AbstractEsqlQuery,
JdbcEsqlQuery, and OracleEsqlQuery at the getQueryString() method.
Pick the one model that suits you best and works with your Oracle.
We'll happily incorporate a patch that allows Oracle to use the
"more-results" feature again :-))

Re: Generic Table printout for Oracle ORDBMS

It boils down to Leon's advice to remove whitespace. Note that I wrote
i
while you write
i
The key is that the macro needs to determine whether it's a string or a
number to deal with. A string would translate to a column name while a
number would translate to a - well - column number.
The whitespace causes it to be considered as column name.
BTW Leon's other advice to use xsp:attriubte does not work since it
targets the SAX stream while you need to pass it to a logicsheet.

Hi Nils, Joerg,
sorry that I can't look into this ATM but I believe the original idea was
that every mail should contain a plain text body, not just attachments.
However, we could for example provide a default text like "please see attachment"
or the like but I feel like it would make more sense to do this application
specific.
So, the simplest solution for Nils would be to add such a body text and add the
pdf as attachment.
I need to dig up the specs to see if it is allowed to have no bodypart. Will try
to look into this over the weekend.
Cheers,
Chris.

(after looking at the code again) this translates to - use autoincrement -> look for a mode "autoincr", if not found use "manual" as shorthand for the module - use the shorthand "auto" as name to locate the actual module that implements the autoincrement feature Therefore you need to have in cocoon.xconf: as the only component instance with the name "auto".

If this doesn't work for you, please post / send me your sitemap.xmap, the database.xml and cocoon.xconf (relevant parts only).

The sitemap is executed *before* any of the sitemap pipeline
components. So, when your transformer sets the attribute, the sitemap
has already tried to read it in order to setup the other transformer.
Only when you do it with an action, the data would be available at
setup time for the transformer. Or your transformers need to
communicate inline through the data stream.

Sure. Your first transformer can add any XML to the data stream and the second can act on it since it needs to read all XML anyway. BTW you can access the session in your transformers since the object model is passed at setup time to it -- you just may not pass the session data through the sitemap to the second transformer! But beware: both transformers *run in parallel* so if the first transformer modifies the session at the end, the second sees the change only very late in the process! tG T T T S iroot-->-->-->--> mh1>-->-->--> e/h1--->-->-->--> |/root->-->-->--> V Chris. -- C h r i s t i a n H a u l [EMAIL PROTECTED] fingerprint: 99B0 1D9D 7919 644A 4837 7D73 FEF9 6856 335A 9E08 - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

These are AFAIR the request-param, request-attr, and session-attr
modules. Actually, this functionality is a concession to the original
database actions. (modules were created during an overhaul of the
database actions.) I believe it's not a very useful feature since it
mimics the getAttributeValues() functionality with several differently
named attributes instead of multiple attributes with the same name in
case of request parameters. There is a difference, though: This way
one can guarantee that multiple fields use the same ordering
e.g. firstname-1:peter, firstname-2:paul, lastname-1:smith,
lastname-2:baker while firstname:{peter,paul} lastname:{smith,baker}
it is not clear that the ordering is correct.

You'll get a parameter named "*" with the some request parameter. The

getAttributeNames will return an iterator over all attribute
names. This contract is somewhat weak: jxpath based modules for
example return only a subset of available attribute names.

No idea. All of them might -- IIRC there's one meta module that
creates a XML representation of the available attributes.

I'm afraid you'll need to do that manually with java. get-parameter-names returns an enumeration of all parameter names. Walk over that, retrieve the name, call get-parameter-values on the name and add it to a map or something. But -- if you need this, you might be better off reconsidering your design. Maybe there is too much logic on your XSP.

Re: [Solution] Re: SimpleFormTransformer - invalid XML generated?
Steve Schwarz wrote: Christian My bad. It looks like the form validation action is the one that doesn't like the enctype="multipart/form-data" together with method="post" but multipart with put is fine as is no enctype with post. In the sitemap.log it reports all fields as null with that encoding/post. Since I'm using simpleform in both the success and failure cases for the validation action I wrongly thought simpleform wasn't working. Since 2.1 processing of uploads needs to be enabled in web.xml. The default case is disabled and you've seen the result :-) Although I think I will try to put a wiki together for the very simple use case; the added complexity of sfinstance in the simpleform sample really had me scratching my head for a while about the simple-form transformer declaration (as a newbie I still haven't gotten my head around the modular mechanism and the classes implementating it). Right. So it ain't "simple" anymore :-| But agreed, the sample is crap. I will try to come up with a better one. I also think I'll try to write a transformer that can transform the descriptor.xml file and into all the entries for each of the validation attributes (min-len, max-len, nullable, etc). I'd hate to enter that info for each error type manually for all my validating forms. To me this is the real power of Cocoon; define the model(s) and drive the site's views entirely from the data models through actions/transformations. A very good idead. And by using the cocoon: protocol this can easily be done with XSLT in an internal pipeline!

It took me a while to figure it out but the problem was my form: If I remove the enctype attribute/value everything works correctly. It shouldn't affect the transformer! If you could send me a minimal sample that shows the problem, I will try to fix it. This is really a great transformer; it sure doesn't seem to get much "press" but it does exactly what I need. Glad you like it :-) If you like this one, you might want to look at its companion, the SimpleFormInstanceTransformer, which basically allows to separate the form data from the form definition: Doe John Unfortunately, I haven't come around providing a good sample for this -- a very small one is located in the simpleform directory (not accessible through the sample pages). I have a better one but that requires a java bibtex parser that is GPLed so I cannot provide that one from the Apache CVS. Anyway, you still might want to look into the more powerful forms approaches in 2.1 like JXForms and Woody.

A static XSLT like the stupid.xsl from the samples should do (it's not brilliant, thus "stupid") Another option is to use the ResultSetMetaData (see esql.xsl) and use JAVA in your XSP to create the table heading. > Is this likely to work with future versions of Cocoon (I did it in > 2.0.4)?

The former is displayed when the result is "error" or worse (when-ge translates to "when greater or equal") while the latter is displayed _only_ in case of "error" e.g. not when it is "too_small".

It's the third line and mine shows for example This is version 1.4 of the file. Knowing the last known good would allow us to see the delta. In addition, could you post the relevant parts of your XSP (i.e. all the esql tags)?

Please have a look at the "Simple Form Handling" sample coming with 2.1.1-dev (CVS snapshot) ;-) (It's hidden with the older releases as well but it should be better understandable with the updated sample.

Use call results *only* if you are accessing regular out
parameters. You have asked to convert the first out parameter to a
ResultSet for you and use that. Hence you need to proceed with

The above error message indicates, however, that you have omitted a
necessary tag or used a wrong ordering. Could you post the complete

Processing of @resultset-from-object has been broken. I've updated CVS
just now. Please update and verify. Anyway, you will still need to
enclose the result with esql:results. Apart from that, you may use
(ResultSet)
...
Which is a little more verbose but IMHO preferable to the
@resultset-from-object syntax.
