What is a CreateTable.ViolationAction ? The method CreateTable.foreignKey(..) has eight different signatures. The argument "localParameter" obviously names the column in "this" table, so what is the meaning of the argument "name" ? If referential integrity is violated at runtime, does Rife give me a specialised exception, or do I get the DB's own exception, unmodified ?

[Rife-users] JBI?
Is anyone else tinkering with JBI ? I'm considering integrating it with my Rife app to get both web services and good external multiprotocol connectivity. Apache ServiceMix is an (AFICT) nice open source implementation of the JBI ESB (Enterprise Service Bus). The internal architecture is message-based, for loose coupling among components. The internal message bus handles normalised XML messages, thus the ESB is also known as a "Normalized Message Router". "Service Units" plug into this bus to provide services, and "Binding Connectors" plug into the bus to do message and protocol translation to external connections. There are some shortcuts provided so that you can put thin wrappers around POJOs and then use them as Service Units. AFAICT it's a short, effective path to getting web services up and running. Plus there's BCs for email, http (incl. an http invoker), ftp, jms,jca, rss, jabber, file systems, saaj, and more. fred -- F.Baube* Georgetown/MSFS/1988 * Think pangalactically. fbaube#saunalahti.fi * Act locally. gsm +358 41 536 8192 * wmd 60°11'10.8"N 24°57'36.9"E ___ Rife-users mailing list Rife-users@uwyn.com http://lists.uwyn.com/mailman/listinfo/rife-users

Rife Forms are truly bidirectional, and can use HTML field validation too. Rife also makes it easy to append to Value tags, in order to generate HTML tables with N rows. But is it possible to generate a Form with N rows, by appending additional rows, where each row is another instance of the same bean type ? That would make it possible to have N-record Forms that are bidirectional and that use HTML field validation. Then the next logical step is to attach some JS that adds an (N+1)th record at the end of the Form. Is this making any sense ?

Re: [Rife-users] Template tag syntaxes
I guess the issues are * edit-time (pre-substitution) behavior: it would be très nice to do DTD-driven editing based on an extension to XHTML (or any other XML DTD :) , and * run-time in-browser (post-substitution) behavior: if there are errors, * does the doc stay well-formed and XHTML-valid (so that a picky browser like FFox does not catastrophically fail to render the document), and * in a rendered XHTML view, are they visible (as faulty RIFE tags) or hidden ? If you want tags to validate _as_XHTML_at_edit-time_, then the XHTML spec doesn't give you much support; there's only one user-defined attribute valid for all elements (IIRC; "class"), so editors would not give you much guidance, and runtime tag parsing & substitution would be a pain in the butt (unpacking multiply-assigned attributes). If common editors could be configured to treat the edit -time doctype as a RIFE extension to XHTML, that would be cool, but I'm not sure that's possible. I'm sure it would very much depend on the editor. Ditto for PI's. (Short list: XXE, Oxygen, Serna.) But then also the runtime templating engine could _change_ the doctype from RIFE-ML to XHTML.

Every framework tries to wire together classes and presentation
and a URL sitemap and so on and so forth, and this simply cannot
be done clearly and consistently with this language at this point
in time. I suspect the sad fact is that in EVERY framework there
is a single point of logical inconsistency where all the ugliness
accumulates, just like a hairball. Or perhaps an abstract class
that implements interface hairball :-)
In Rife it's in the templates, but (as has been mentioned previ-
ously in this thread) the syntax is HTML editor -friendly, and
the functionality is logicless and bidirectional, so the syntax
has its upside. And it also means that as compensation, the
declarations of submissions and the usage of templates are
relatively painless and straightforward to understand.
In other frameworks the dead bodies (or, "gotchas") are more
deeply buried, or the appealing simplicity breaks down much
more drastically at a more painful point in the framework.
This seems to be the focus of the Java-v-Ruby debate right
now. It's like learning a foreign language. Each language
has its point where suddenly the bloom is off the rose and
oh crap! now you feel like you are pounding nails into your
head. For example, I've read that with spanish the first two
years are smooth sailing but the third year is the killer.
With english the first year is a total breeze ("Grammar?
WHAT grammar?!") but there's a pretty nasty brick wall
somewhere around the next corner.
Rife's template syntax is ugly because the (inevitable) seams
in the framework pop up in the presentation-layer markup. But
OTOH you could troll the mailing lists of other frameworks to
find out where _they_ bury _their_ dead bodies.
HTH! :)

Cool, but pretty confusing if one wants it to return data. The docs are
inconsistent regarding the necessity of the generic parm "ResultType".
If I understand the docs and the source code correctly, ...
1) I can use it with GQM's (if the GQM's are within compilation scope)
like so:
final DbQueryManager manager = new DbQueryManager(MyDatasource);
DbTransactionUser MyTxn = new DbTransactionUser(List Objs)
{
public void useTransaction() throws InnerClassException
{
Objs.add (GQM_1.doSomething());
Objs.add (GQM_2.doSomething());
GQM_1.doSomethingElse();
}
};
try { manager.inTransaction(MyTxn);
// success!
List ResultsOfSuccessfulTxn = MyTxn.getData();
}
catch (Exception e) {
// failed; rolled back
}
2) An implicit commit() is performed at the _end_ of the
code block if and only if, _within_ the code block,
a) no exception is thrown, and
b) rollback() is not explicitly called.
3) Therefore, _all_ DB actions that are to be grouped into a single
transaction must be grouped within this same single code block.

Speaking of which ... to revisit an old topic ...
I need Rife's transaction support, which AFAICT is not available at
all to GQM's.
(I originally used GQM's in order to get the unique sequential ID's,
but I no longer need them, so it's time to make the switch.)
Does the changeover start by
1) replacing calls to
GenericQueryManagerFactory.getInstance
(Datasource datasource, Class beanClass, String tableName)
with
new DbQueryManager(Datasource datasource)
2) and using the << .into("tablename")" >> method
3) and making sure that each table has a column with the "unique" Constraint

[Rife-users] Own CredentialsManager
I find that I'd like to write my own implementation of com.uwyn.rife.authentication.CredentialsManager, so that I can decide at runtime what source(s) to use for authentication info. The CM interface couldn't be simpler, but obviously it is necessary to assign a unique << (long) userid >> to every username. This mapping between usernames and userid's does not need to be consistent _between_ application sessions, only _within_ an application session, yes ? So, then, it is entirely the responsibility of my own CM implementation to devise a mapping between usernames and userid's that both (a) creates unique userid's, and (b) keeps the mapping consistent -- within a particular session -- _across_ calls to verifyCredentials(..) ? thx fred -- F.Baube* Georgetown/MSFS/1988 * Think pangalactically. fbaube#saunalahti.fi * Act locally. gsm +358 41 536 8192 * wmd 60°11'10.8"N 24°57'36.9"E ___ Rife-users mailing list Rife-users@uwyn.com http://www.uwyn.com/mailman/listinfo/rife-users

Re: [Rife-users] Rife+Tomcat env.var problem
Apparently I need to execute code before the DB driver is loaded.
Quoting Geert Bevin:
>

Of course. My oversight.
But the problem persists. When we take system env.variables and
define them to the JVM using "-D", the short test program can see
them, and Rife on Linux can see them, but Rife on Windows can_not_.
Something is screwed up.
Per http://db.apache.org/derby/docs/10.1/tuning/tuning-single
under "Ways of setting Derby properties" : "Using a properties
object within an application or statement", I can set the value
programmatically with a call like this:
Properties p = System.getProperties();
p.put("derby.system.home", "C:\databases\sample");
BUT it also says that "you can also set system properties within
an application using a Properties object before loading the Derby
JDBC driver."
SO ... is there a way to execute code _before_ the driver is loaded ?

Re: [Rife-users] Rife+Tomcat env.var problem

My partner ran this program:
public class JT {
public static final void main (String [] args) {
System.out.println ("DERBYDB_HOME: " + System.getProperty("DERBYDB_HOME"));
System.out.println ("derby.system.home: " +
System.getProperty("derby.system.home"));
} }
and he reports:
well, it gives all nulls.
but when I check them like 'echo %DERBYDB_HOME%' etc. or
from the windows control panel, I get the correct values.
SO, I'm stumped. But I guess it's not a Rife issue ...

[Rife-users] Rife+Tomcat env.var problem
I'm not sure whether this is a Rife question or a Tomcat question,
but maybe someone has seen this before and can help me out.
Simply put, we set environment variables (like, for example,
DERBYDB_HOME) but my Rife app cannot see them.
I fetch them with calls like this in my Rep startup code:
HierarchicalProperties PP = Rep.getProperties();
String DERBYDB_HOME = PP.getValueString ("derby.system.home");
This works fine on Linux, where I set env.vars in Tomcat's
startup.sh, but it does not work on Windoze.
We've tried settign them in Tomcat's startup.bat, and also
in Tomcat's Windoze manager GUI.
Does this sound familiar to anyone ?
thx much

It did seem to fix it !

[Rife-users] Possible classloader problem?
I have a problem that I've burned a couple of days on, without
success. Now my latest testing makes me wonder if it might be
a classloader problem related to Rife.
Further down in this message is a code fragment that tries to
set the "lexical-handler" property of a SAX XMLReader, like so:
reader.setProperty(LEXICAL_HANDLER_PROPERTY,this);
The classes that use this fragment implement SAX's LexcalHandler.
When I execute it inside a simple servlet class like this:
public class HelloWorldExample extends HttpServlet
implements ContentHandler, LexicalHandler
{
public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException
it is able to set the lexical-handler property of the parser.
But when I execute it in class that is called from a Rife
Element, like so:
public class WriterLex extends DefaultHandler2 {
it _always_ fails on the call
FWIW I've also tried
WriterLex implements LexicalHandler {
and a dozen other combinations.
I've done my best to narrow it down this problem, I've tried
configuring XMLReaderFactory's and SAXParserFactory's, but
the call to setProperty(..) consistently fails inside Rife.
Does this sounds like any known problems with classloading ?
fred
the code fragment:
public static final String SAX_DRIVER_PROPERTY = "org.xml.sax.driver";
public static final String LEXICAL_HANDLER_PROPERTY =
"http://xml.org/sax/properties/lexical-handler";;
try {
if (System.getProperty(SAX_DRIVER_PROPERTY) == null){
//The default sax driver is set to xerces's sax driver
System.setProperty(SAX_DRIVER_PROPERTY,
"org.apache.xerces.pars\ers.SAXParser");
}
reader = XMLReaderFactory.createXMLReader();
// I also tried "com.sun.org.apache.xerces.internal.parsers.SAXParser"
System.out.println ("Clsnm: " + reader.getClass().getName());
reader.setContentHandler (this);
reader.setProperty (LEXICAL_HANDLER_PROPERTY,this);
System.out.println ("SUCCESS!");
}
catch (Exception e) {
e.printStackTrace();
}
}

[Rife-users] Steps of authentication
In the HTTPAuthentication example, there are
two distinct steps in credentials validation:
1) RoleUser credentials = new RoleUser(username, password, role);
if (credentials.validate()) { [..]
2) long userid = MemoryUsers.getRepInstance().verifyCredentials(credentials);
if (userid >= 0) { [..]
Apparently step 1 only makes simple checks about
the existence of arguments, while step 2 performs
the actual check of the username+password combo ?
curious,
fred

This code works fine. Thanks !
I need to have this code set cookies, for compatibility
with other code, and I see that the relevant code is in
com.uwyn.rife.authentication.elements.Authenticated.startNewSession().
I wonder if it might make sense to have HttpAuthentication
_extend_ Authenticated, or perhaps even RoleUserAuthenticated ?
Perhaps not ... The code as-is is a good example of how
to write your own standalone authentication element :)
Also, I would like HttpAuthentication to accept a _set_ of
roles, so that a user could login who has _any_ of these
roles, and then an exit is selected based on the role.
Like so:
[ sitemap ]
role1 role2 role3
[ HttpAuthentication ]
if (theRole.equals ("role1")) redirect ("/foo/menu");
if (theRole.equals ("role2")) redirect ("/bar/menu");
if (theRole.equals ("role3")) redirect ("/byob/menu");
I guess then that code for credentials validation could be
modified to try each username+password+role combination,
until one succeeds:
SessionManager sessionMgr = MemorySessionsFactory.getInstance();
SessionValidator validator = new MemorySessionValidator();
MemoryUsers credentialsMgr = MemoryUsers.getRepInstance();
validator.setCredentialsManager(credentialsMgr);
validator.setSessionManager(sessionMgr);
validator.setRememberManager(null);
String username = cred_arr[0];
String password = cred_arr[1];
List roles = StringUtils.unpack(getPropertyString("role"));
for (String role : roles) {
RoleUser credentials = new RoleUser(username, password, role);
if (credentials.validate()) {
// succeeded; select appropriate exit
[..]
thx
