Re: Problem with Resuable Component and ^ "operator"
I made it stateless. Turning it into stateful might solve the problem. but it'll be very cool if this can be solved without doing so. If from within a component, the binding keyPath (with or without the leading ^ according to the actual definition in .wod file ) can be obtained, the issue should be easily resolved. - Original Message - From: Art Isbell To: WebObjects (Group) Sent: Friday, June 30, 2006 7:36 PM Subject: Re: Problem with Resuable Component and ^ "operator" On Jun 30, 2006, at 2:51 PM, YL wrote: Consider DateTimeField as a reusable component that displays / admits an NSCalendarDate value.

Re: Jboss 4.0.x deployment
Hi Andrew,WebObjects is clever because it uses the standard EOModel database connection in development and then when you deploy (and is uncommented in web.xml.template) EOF ignores the EOModel connection string and automatically uses the jboss data source connection which of course could be to a different database.For development I am using XCode 2.3 WebObjects 5.3.1 When starting the project I selected true WAR (frameworks must be built as jars)I built an EOModel which matched the data structure in the postgresql 8.1.3 database. I am using the postgresql-8.0-310.jdbc3.jar jdbc driver in /Library/Java/Extensions. I am using the Project wonder PostgresqlPlugin.framework in /Library/Frameworks. I am using case sensitive field names so I had to set the property in Application.java constructor System.setProperty("com.webobjects.jdbcadaptor.PostgresqlExpression.enableIdentifierQuoting","true");For deployment I am using jboss 4.0.3SP1 on a debian system with 2.6 kernel and java 1.5.0_06. To prepare my app for deployment I used a WebObjects 5.3 licence key in SERVLET_DEPLOY_LICENSE in main project target.My jboss-web.xml "http://www.jboss.org/j2ee/dtd/jboss-web_3_2.dtd"> jdbc/DefaultDataSource java:/PostgresDS From my web.xml.template The data source to be used by EOF. If there are multiple data sources, then the definition below must be used to configure which JDBC URL (Model) should use which data source. If EOF should use a JDBC driver directly, this section must be commented out jdbc/DefaultDataSource javax.sql.DataSource Container From postgres-ds.xml in jboss deploy directory PostgresDS jdbc:postgresql://192.168.0.1:5432/my_database org.postgresql.Driver my_username my_password PostgreSQL 8.0 To ensure the PostgresqlPlugin.framework was built as a jar I ran the following command/Developer/Makefiles/java_makefiles/CoaxBundleIntoJar.sh /Library/Frameworks/PostgresqlPlugin.framework /Library/WebObjects/libI also had issues with primary key generation because the sequences in the database didn't match the sequence names that the framework was expecting. For each eogenerated model subclass class I overrode the method awakeFromInsertion with the following: public void awakeFromInsertion(com.webobjects.eocontrol.EOEditingContext ec) { if ( ec != null && idEnquiry() == null ) { String sql = "select nextval('my_schema.\"Enquiry_EnquiryNumber_seq\"'::text);"; NSArray ar = com.webobjects.eoaccess.EOUtilities.rawRowsForSQL(ec, "my_eomodel", sql, new NSArray("id")); if ( ar.count() > 0 ) { NSDictionary nsd = (NSDictionary) ar.objectAtIndex(0); setIdEnquiry((Number) nsd.objectForKey("id")); } } }I hope this helps.D Tim CummingsTriptera Pty LtdOn 30/06/2006, at 13:49, Andrew Madu wrote:Hi D,I am using postgresql within jboss 4.0.x in exactly the same way, using postgres-ds.xml, with my current cocoon/hibernate project.

Host in WO URL (was "No Instance available" message)

Problem with Resuable Component and ^ "operator"
Hi List,
Consider DateTimeField as a reusable component that displays /
admits
an NSCalendarDate value.
In a wod file, it may appear like
ScheduledTime: DateTimeField {
value = scheduledTime;
timeZone = session.preferedTimeZone;
editable = isEditing;
language = session.language;
..
}
The component takes a value from binding and presents the
value as a value set
(year, month, day,... in specified language/format/locale ),
and takes the updated
value set to update the binded value
accordingly.
Now suppose I put a DateTimeField into a component, say
AdminBox, and embed
the AdminBox in an EventEditor page. Then in AdminBox.wod,
Date Field may
be defined like
ScheduledTime: DateTimeField {
value = ^scheduledTime;
timeZone = session.preferedTimeZone;
editable = ^isEditing;
language = session.language;
..
}
the operator ^ means that its following keyPath is relative to
the parent component
(in our case, AdminBox is supposed to have bindings
scheduedTime and isEditing)
The trouble that I encountered is that when form submitted,
the case where direct
bindings are used worked as expected, but the latter case
(using ^)yields exception:
*** object is unsettable for keyPath
^scheduledTime...
Replace DateTimeField with something simpler like WOTextField,
both cases worked
just fine. This is understandable: In my DateTimeField, I
used
[self setValue: _date forBinding: @"value"]
to set the value with the nornalized date object. But
-(void)setValue:forBinding:
doesn't work well with the operator ^
Any ideas? Thanks in advance

It appears the diagnosis is correct, it's not the code, it's that I
am missing (or have a conflict between) mail.jar and/or

Confirmed this using debugging and this code
Transport transport = null;
transport = mailSession.getTransport("smtp");
transport.send(msg);
Program blows at getTransport("smtp") and debugger says the
variable is out of scope (meaning, I'm assuming, uninitialized).
I have looked at the classpath document in my .woa app and followed
each path (only three) to the Java->extentions folders and
WebObjects folders and have only found one copy of the latest
version of mail.jar and activation.jar.
The classpath file in the app points to the Java->extentions folders
and WebObjects->extensions folders? That does not sound right. If
you have done that, you hare probably having a classloader / security
problem that is getting mis-reported.
At this point the problem seems to have been isolated but the cause
is unclear. For what it is worth, I recently upgraded to the latest
Java version and developer tools.
Any suggestions?
I'll suggest what others have: undo all your changes related to this
(uninstalling the jars etc) and use the Wonder framework for mail.
Otherwise, Google is probably your best bet as this problem seems
unrelated to WO.

JavaMail is complex. I understand only the bare minimum that

unreliable. To make WOMailDelivery easily replaceable, I created
a JavaMailDelivery class that uses JavaMail underneath and
reimplemented WOMailDelivery.composePlainTextEmail() as
JavaMailDelivery.composePlainTextEmail(). I basically copied the
implementation of send() at adding exception handling where
needed and relying on properties in the Properties file rather
than hard-coding their values. It works fine.
SendFailedException: javax.mail.NoSuchProviderException: smtp
According to the JavaMail javadoc, NoSuchProviderException is
thrown when the JavaMail "Session attempts to instantiate a
Provider that doesn't exist." A Provider is the description of a
protocol implementation. In your case, the "smtp" protocol
implementation doesn't seem to exist. Maybe you need to set the
mail.store.protocol and mail.transport.protocol properties in
your Properties file or maybe your JavaMail implementation is
broken. I have no idea.
Art is correct. You are misinterpreting the meaning of the
exception. It is not saying that it can't find your SMTP server,
it is saying that it has no idea what SMTP _is_. My guess is that
this means one of:
1. You installed mail.jar and activation.jar in the wrong place.
They should be in one of /Library/Java/Extensions or Library/
WebObjects/Extensions.
2. You have conflicting versions of mail.jar and activation.jar in
the directories above or elsewhere
3. One of these files is missing or corrupt

Re: How to skip items in a WORepetition ?
Yes, using EOQualifier.filteredArrayWithQualifier(someArray, someQualifier) is the way to go. Assuming that the objects contained within the NSArray are Key Value Coding (KVC) compliant.Just thought I would add that clarification. If they are not KVC compliant then you need to write your own custom filtering algorithm.On Jun 30, 2006, at 12:03 PM, Sam Barnum wrote:I'd recommend filtering the item in the java code.

Re: Jboss 4.0.x deployment
Ok, I had to comment out the ticoon logging references so it would compile without dependancy http://WOCode.com/cgi-bin/WebObjects/WOCode.woa/wa/ShareCodeItem? itemId=459 Here are the notes I added: - WebSphere (at least for version 5 which our client uses) will not tolerate subthread data access. According to my understanding of the Servlet container spec, subthreads are not covered and so their behavior is not predictable. We experienced all kinds of weird behavior due to differences in properties, class loaders and JNDI contexts from the 'main' threads and the subthreads. - I have included some of our TApplication.java subclass code. This code shows how we configure EOModels when they are loaded and how we install the JavaWSPoolJDBCAdaptor as needed. - the TApplication code also shows (although it will not compile) the logic we use for WebSphere Single Sign on. This same code also works with Tomcat for another client who uses NTLM SSO. - If you build multiple apps into an EAR file, this adaptor must be in the /lib/ directory of each application WAR file. Just like the WebObjects jar's, it must be there or the class loaders will mess it up. If anyone can explain this and or how to fix it (I hate duplicating all those jars) I would appreciate the help.

Application Servers Developer Preview Build 7K248

Meanwhile the development, i am looking for WO hosting services, the only one i found still now who offer good prices (i mean who i can afford) is www.systame.com, does anyone know how reliable they are ? Secondly, in the case i don't find a good wo hosting provider, i intend to deploy the web application as a servlet, so i'd like to install Tomcat and/or JBoss on my OS X Client, i saw that Apple offer the "Application Servers Developer Preview Build 7K248" on his ADC Member site. Is it the good tool to test a servlet deployment of a WOapp, has anyone used it and may share his experience with it ? Or is it better to install Tomcat and/or Jboss separately from the binary available from their official website ? Thanks for your comment. Gilles. ___ Do not post admin requests to the list.

Re: Binding synchronization timing problems
With WODisplayGroup you also get the advantages of being able to set filters and sorting preferences too. Also, there is nothing to prevent the binding of this WODisplayGroup to a batch navigation bar (even with the array as the data source). Then you get the benefit of the user being able to set the number of records per page, specify the current page, and automatically view the total number of pages and records. Just don't put the batchnavbar in a form ;-). It is its own form and nested forms aren't allowed.JohnOn Jun 30, 2006, at 7:34 AM, Mike Schrag wrote:Just to second this one ..

Re: Binding synchronization timing problems
In tandem to Chuck's diagnosis, the component appears to be working
exactly as designed, just not as intended. Remember, the generator
will not pass the bindings along to the component until it finds the
component in the course of page generation. That means that the
bindings will not be passed to the pagercomponent until it the
pagercomponent is generated. In your case, the pagercomponent is
generated after the repetition, so the generator isn't going to pass
the bindings to the pager component until the repetition has already
got its partialList from the pager. The caveat to this is when there
is form submission or a specific action. For instance, calling the
"nextPage" action against the pager. This will run this code first,
which is why you are seeing some behavior.
So, as to the solution, I would recommend trying adding
pullValuesFromParent() to the getReviewersPartialList() method
(perhaps the first line of the method). This method causes the
bindings to be brought in to the component ahead of the normal
binding time (component generation). It is ok to do this so long as
you remember that it is there, and so long as you use the component
the same throughout your ap. When the repetition calls the
getReviewersPartialList, the method will get its bindings bringing in
the list, and then it will have the list. When the component is
generated, the bindings will be reapplied, but it won't matter.

Hi!
I'm having some strange problem here, and I still could not

Mysteries of Binding Synchronization on Practical WO book.
I have a table in my page, made with a WORepetition component. I
wanted to write a pager component, to "page" the table. So I
did! :) To link together the pager and the repetition, I used the
following schema:
Pager: PagerComponent {
partialList = reviewersPartialList;
originalList = reviewersList;
}
ReviewerRepetition: WORepetition {
list = reviewersPartialList;
item = currentReviewer;
index = currentIndex;

Re: JavaMail Props Not Being Set
It appears the diagnosis is correct, it's not the code, it's that I
am missing (or have a conflict between) mail.jar and/or activation.jar.
Confirmed this using debugging and this code
Transport transport = null;
transport = mailSession.getTransport("smtp");
transport.send(msg);
Program blows at getTransport("smtp") and debugger says the variable
is out of scope (meaning, I'm assuming, uninitialized).
I have looked at the classpath document in my .woa app and followed
each path (only three) to the Java->extentions folders and WebObjects
folders and have only found one copy of the latest version of
mail.jar and activation.jar.
At this point the problem seems to have been isolated but the cause
is unclear. For what it is worth, I recently upgraded to the latest
Java version and developer tools.
Any suggestions?

Drew

JavaMail is complex. I understand only the bare minimum that
allowed me to build a replacement for WOMailDelivery which can be
unreliable. To make WOMailDelivery easily replaceable, I created
a JavaMailDelivery class that uses JavaMail underneath and
reimplemented WOMailDelivery.composePlainTextEmail() as
JavaMailDelivery.composePlainTextEmail(). I basically copied the
implementation of send() at adding exception handling where
needed and relying on properties in the Properties file rather
than hard-coding their values. It works fine.
SendFailedException: javax.mail.NoSuchProviderException: smtp
According to the JavaMail javadoc, NoSuchProviderException is
thrown when the JavaMail "Session attempts to instantiate a
Provider that doesn't exist." A Provider is the description of a
protocol implementation. In your case, the "smtp" protocol
implementation doesn't seem to exist. Maybe you need to set the
mail.store.protocol and mail.transport.protocol properties in your
Properties file or maybe your JavaMail implementation is broken.
I have no idea.
Art is correct. You are misinterpreting the meaning of the
exception. It is not saying that it can't find your SMTP server,
it is saying that it has no idea what SMTP _is_. My guess is that
this means one of:
1. You installed mail.jar and activation.jar in the wrong place.
They should be in one of /Library/Java/Extensions or Library/
WebObjects/Extensions.
2. You have conflicting versions of mail.jar and activation.jar in
the directories above or elsewhere
3. One of these files is missing or corrupt

Yes, it is possible. I know many WO sites that do things like
this. It is just hard to understand all the pieces the first time.
You need two things:
1. The WO components / HTML to define the plugin in HTML
2. A direct action (this is easiest, I think) so you have a URL to
dynamically return the MP3 data (see downloading below)
Then use the direct action URL as the src (I think that is the one)
in the EMBED tag.
I think you can do this all in one step with WOEmbeddedObject, but
this way is probably easier to understand.

It is used by the project that I got in January. The main feature is that it does some auto-encoding of entities and hosts, which makes it possible to have multiple DBs and sync them later on. I still don't like it, as it increases the number of PKs with each start of the app by 1000, which is a bit wasteful (granted, with 64 bit you have a lot of room, though) and you need to call it directly, as opposed to simply override the DBC delegate where it would rather belong in. So if I get some time, there´s some refactoring due here For now I have chosen to use 24 byte binary primary keys generated by EOF, but I'm not really happy with them. They are hard to use with other tools, even when just doing some fetches for one row in the db tool just to test something. We use these for our main product. Works quite well when you use PG with the hex-encoded keys. A pain when you don't. Also, performance may or may not be impacted. And they are also wasteful as half of these 24 bytes are zero.
