Hi all,

I’m just curious, what is Wonder-slim?

Thanks

Can't open WO components after Eclipse upgraded to Version 2023-06

2023-06-23 Thread Ricardo Parada via Webobjects-dev

Hello everyone,

My Eclipse upgraded itself to Version 2023-06.  I first noticed my WOLips 
perspective button turned into WOLips text.  I also had compilation errors.

I had to reinstall WOLips.  Now the WOLips icon for the WOLips perspective is 
showing normal, e.g. the one that looks like an EO.

But now, Eclipse won’t open any of my WO components.

Anybody having these problems?

Thanks,
Ricardo Parada

Re: Variables in .classpath for selecting log4j Framework?

2023-05-22 Thread Ricardo Parada via Webobjects-dev

We are using ant. And yes I kicked out the JavaXML framework. I added some jars 
to ERJars/Libraries to get ERExtensions to compile. 

I wrote a little script using the find and sed Unix commands that replace the 
framework in all the .classpath files. 

Thank you

Variables in .classpath for selecting log4j Framework?

2023-05-19 Thread Ricardo Parada via Webobjects-dev

Hi everyone,

Our build system is still using ant and relies on the .classpath entries. 

I have added a couple of frameworks to our Wonder fork:

* ERLog4j1Extensions
* ERLog4j2Extensions

If I want my apps in to use the old log4j 1.2 logging library then I simply put 
a classpathentry in the .classpath for the ERLog4j1Extensions framework like 
this:

 

If I want to switch to the latest log4j2 then I replace the above with an entry 
for the ERLog4j2Extensions framework like this:



The problem is that I have a lot of apps that need their .classpath updated. 
And switching back and forth during my testing is a lot of .classpath that I 
need to update. I could probably write a script but I’m hoping there is an 
easier way. 

Is there a trick to make the logging framework a variable that can be set 
externally somewhere else and all the .classpath files pick it up, e.g. 
${ERLoggingFrameworkName} and without breaking Eclipse? ;-D

Thanks for any ideas
Ricardo Parada

Re: Replacing log4j with slf4j in Wonder

2023-03-11 Thread Ricardo Parada via Webobjects-dev

Hi René I used Henrique’s fork to help us advance our Wonder fork to slf4j.I commented out references to classes in ERXLog4j2LoggingAdapter and ERXLogbackLoggingAdapter because we still have an ant based build and I don’t know how to specify optional dependencies as he seems to have done in the pom.xml for maven. I am moving classes to separate frameworks as you and him had discussed. For example, ERLog4j1Extensions, ERLog4j2Extensions and ERLogbackExtensions. The application decides which logging library to use by adding one of these to their .classpath / pom.xml. For this to work I moved the slf4j log4j1 binding library from ERJars to ERLog4j1Extensions. I also rewrote the currentBinding() and createLoggingAdapter() in ERXLoggingUtilities to look up classes by name rather than referencing the classes directly which requires optional dependency for the code to compile. My application is working and using ERLog4j1Extensions. I’m am converting ERXPatternLayout and its converter classes to their equivalent in log4j2 and I will be putting them in the ERLog4j2Extensions framework. Once I have completed that portion and can launch my app successfully I’ll report back.

Re: ERJGroupsSynchronizer

2022-03-28 Thread Ricardo Parada via Webobjects-dev

Hello, all, here’s a plain text version of my previous email, in case anybody 
had trouble reading it.

I created this subclass to keep EOF in sync within a single java VM:


/**
 * Keeps EOF in sync within a single java VM.
 *
 * Wonder's ProcessChangesQueue seems to takes care of keeping
 * in sync EOF stacks used in other threads.
 */
public class LocalSynchronizer extends ERXRemoteSynchronizer {
 
public LocalSynchronizer(IChangeListener listener) {
super(listener);
}
 
@Override
public void join() throws Throwable { }
 
@Override
public void leave() throws Throwable { }
 
@Override
public void listen() throws Throwable { }
 
@Override
protected void _writeCacheChanges(int transactionID, NSArray 
cacheChanges) throws Throwable
{
// Nothing to write to the group
} 
}



To use it you use these properties:

# Synchronization across EOF stacks (single VM)
#
# NOTE: The maxCoordinator property is needed to trigger the of
# initialization the synchronizer.
#
er.extensions.ERXObjectStoreCoordinatorPool.maxCoordinators=1
er.extensions.remoteSynchronizer.enabled=true
er.extensions.remoteSynchronizer=com.mpv.eof.LocalSynchronizer

Notice that the properties to specify which entities to include / exclude is 
not needed as the filtering of changes by entity seems to be used only when 
deciding which changes to send to remote instances.

Re: ERJGroupsSynchronizer

By the way, here’s a synchronizer subclass I wrote to  keep changes in sync 
within a single java VM.


/**
 * Keeps EOF in sync within a single java VM.
 *
 * Wonder's ProcessChangesQueue seems to takes care of keeping 
 * in sync EOF stacks used in other threads.

public class LocalSynchronizer extends ERXRemoteSynchronizer {
 
public LocalSynchronizer(IChangeListener listener) {
super(listener);

@Override
public void join() throws Throwable { }
 
@Override
public void leave() throws Throwable { }
 
@Override
public void listen() throws Throwable { }
 
@Override
protected void _writeCacheChanges(int transactionID, NSArray 
cacheChanges) throws Throwable 
{
// Nothing to write to the group
} 
}

To use it you use these properties:

# Synchronization across EOF stacks (single VM)
#
# NOTE: The maxCoordinator property is needed to trigger the of
# initialization the synchronizer.
#
er.extensions.ERXObjectStoreCoordinatorPool.maxCoordinators=1

Thank you all for the responses.

When we put the ERJGroupsSynchronizer in production we started receiving 
reports of users not being able to access the application instances or getting 
kicked out of the application.  I do not know if the ERJGroupsSynchronizer is 
the one to blame.  So I think it would be unfair to blame the problem on 
ERJGroupsSynchronizer.

We just noticed the these warnings in the console and the first thing we tried 
was to disable the synchronizer and the problem seems like it disappeared after 
we did that.

WARNING: JGRP15: the send buffer of socket MulticastSocket was set to 5MB, 
but the OS only allocated 212.99KB. This might lead to performance problems.

This seems like it could be fixed by increasing the max send buffer on the

The testers in our UAT environment noticed the following warnings:

WARNING: JGRP12: discarded message from different cluster UATClaimScrubber 
(our cluster is UATContractManager). Sender was 
f677bf19-c5e7-a69e-2000-97638a06f579 (received 4 identical messages from 
f677bf19-c5e7-a69e-2000-97638a06f579 in the last 64665 ms)

I think this just means that two different instances with a different 
application name are using the same multicast address.  Nothing really harmful. 
 This could probably be taken care of by setting the group name to the same 
name on both.

If I get any additional information I will post my findings.

Thank you all,
Ricardo J. Parada

ERJGroupsSynchronizer

2022-03-18 Thread Ricardo Parada via Webobjects-dev

Hi everyone,

Does anybody use ERJGroupsSynchronizer?

I’m trying to synchronize two EOF stacks within a single VM. I don’t want the 
synchronization to happen across application instances. 

The video from Mike Shrag from a WOWODC conference said it can be single VM or 
across VM. I’m interested in the single VM but have not yet figured out how to 
do it. 

Basically, I have a background task doing work on a separate EOF stack and I 
want the changes to reflect on the EOF stack used by the user interface without 
resorting to fetching. 

Thanks for any help

Hi Johann,

My workaround is to model the relationship as a to-many propagating the primary 
key.   It’s less elegant but at least it works.

To-one relationship with propagating primary key

2019-01-13 Thread Ricardo Parada

Hi all,

I have an entity A with a to-one relationship to entity B. 

The relationship is setup in eomodeler to propagate it’s primary key from A to 
B. 

 I then create A and B, insert into editing context and set the to-one 
relationship in A to point to B. When I save changes EOF is trying to insert 
TWO instances of B. The second instance of B has NULL in all its properties:

INSERT INTO HOSTING_COMPANY(CUSTOMER_ID, name) VALUES (?, ?)" withBindings: 
1:20462(customerID), 2:"test"(name)>

INSERT INTO HOSTING_COMPANY(CUSTOMER_ID, name) VALUES (NULL, NULL)
 

Is this a know bug? I am using a very old version of Wonder. 

The relationship is also set up to own the destination and Cascade on Delete. 

Thanks in advance for any help. 

Ricardo

Problem calling NSBundle.bundleForClass from junit test code

Hi all,

I am running a junit test case. The code there wants to load a file that 
resides in the Resources folder from the framework bundle. That framework is 
where the class I am testing and the junit class reside.  

However, this returns null:

NSBundle bundle = NSBundle.bundleForClass(MyClass.class):

Any ideas?

WOLips error: The class for 'XYZ' is either missing or does not extend WOElement

2018-04-04 Thread Ricardo Parada

Hi all,

For a long time I’ve seen error messages such as the one below when in the WO 
component editor in WOLips in Eclipse:

The class for 'AjaxModalDialogOpener' is either missing or does not extend 
WOElement.

Does anybody know why that is?  Is this a known bug or am I doing something 
wrong? The Ajax framework is in the class path of the framework that uses the 
AjaxModialDialogOpener.

Thanks

Hi Michael,

It appears one of the objects being saved is for a read only entity.  Can you 
tell if that is what is going on?

Re: File update issues with Eclipse

2017-12-08 Thread Ricardo Parada

Hi Markus,

I’ve seen the problem you have described when editing WO components. I don’t 
know what causes it. When it tells me that the file has changed and whether I 
want to reload it I usually just say no because I know I have not changed the 
file from underneath Eclipse.

Can EOF stream from file to database?

2017-04-06 Thread Ricardo Parada

Hi all,

Using JDBC I can stream the contents of a file to the database as follows:

File file = …;
FileInputStream stream = new FileInputStream(file);
PreparedStatement ps = connection.prepareStatement("INSERT INTO FILE_CONTENT 
(ID, CONTENT) VALUES (?,?)");
ps.setString(1, fileContentID);
ps.setBinaryStream(2, stream, (int)file.length());
ps.execute();
ps.close();
connection.close();

Is it possible to do something similar in EOF.  I thought that maybe if I 
created the NSData like this:

File file = …;
FileInputStream stream = new FileInputStream(file);
NSData data = new NSData(stream, 1024);
FileContent fileContent = FileContent.create(editingContext);
mimeContent.setContent(data);
editingContext.saveChanges();

However, creating the NSData object with the stream seems to read all the data 
into memory.

Is it possible to do this in EOF?  I'd prefer to use EOF so that I don't have 
to create a new connection to the database to do this.

Thanks
Ricardo Parada

Re: ERXWOConditional - where does it get installed?

2017-03-21 Thread Ricardo Parada


Thanks Johann.

I'm confused because in my test I was seeing 3 x 5 for #3. Each session had 3 
dynamic elements created.  The dynamic elements started being shared within the 
same session when I started creating multiple instances of the page. All the 
pages in the session started using the same three dynamic elements. But other 
sessions kept on using their own. Each of the 5 sessions was using three.

So I am not sure why I see that behavior and you see only 3 being created. 

But if they work as you described #3 then yes I can see trouble big time. 

To make things worse I have not found great documentation on how they are used 
by WebObjects. I will take a look at that session that you mentioned.

Re: ERXWOConditional - where does it get installed?

2017-03-21 Thread Ricardo Parada

Was that in a session-less app instance perhaps? I have not tested that 
scenario. 

In my test I do not see dynamic elements being shared across sessions, so I'm 
not seeing exactly how is it that concurrency plays a role in the session app 
scenario where the dynamic elements are not shared with the ones from other 
sessions processing a request at the same time. 

But again, there may be something else, a property or something that affects 
this sharing that I may be missing. 

Anyways, the consensus is that it is a bad idea, so I'll follow advise and 
implement it as a WOComponent subclass instead. 

Thank you all.

Re: ERXWOConditional - where does it get installed?

2017-03-21 Thread Ricardo Parada

Hi all,

I’m just reporting back on my findings on whether saving state between 
appendToResponse and a subsequent takeValuesFromRequest in a dynamic component 
is bad or not.

I read Chuck’s Practical WebObjects, p. 193 where it talks about Dynamic 
Elements.  As he pointed out there, dynamic elements are shared among all 
instances of a WOComponent subclass.  My MPVWOConditional is implemented as a 
dynamic element because it extends ERXWOConditional which then extends 
WODynamicGroup which then extends WODynamicElement.

To test this I created a Hello app with a single page, Main.wo.  I have three 
MPVWOConditionals in there.  An instance is created for each occurrence of my 
MPVWOConditional in Main.  A total of three to be exact.  

I then have a link on Main that calls an action returning a new instance of the 
page Main:

public WOActionResults newPage() {
return pageWithName(Main.class);
}

Every time this newPage() action gets called I can confirm that the constructor 
in Main gets called, which indicates that a new page is being created every 
single time this action gets called.  

However, the constructor of the MPVWOConditional is not getting called three 
times as when the first/second time the page was created.  On the other hand, 
the appendToResponse() of the MPVWOConditional keeps getting called three 
times, once for every instance of MPVWOConditional in Main.  The hashCode() of 
each of these three MPVWOConditional coincides with the ones that were 
previously created.

To summarize, when new instances of the page are created, the MPVWOConditionals 
are being reused on new instances of the page.

Fortunately, the dynamic components are not shared among page instances from 
different sessions.  Which makes sense.  The sharing only applies among 
instances within the same session.

I can see how some might object to storing this state in the dynamic component. 
 It has worked like this all this time.  It’s the way it works.

However, I think it is okay to save this piece of state between an 
appendToResponse and a subsequent takeValuesFromRequest because the 
takeValuesFromRequest is being done on the same page that generated the 
appendToResponse.  

Furthermore, if a new page is created and the components are shared, their 
appendToResponse will get called and this piece of state will be re-computed 
and saved awaiting a subsequent takeValuesFromRequest.  

Now, let’s assume that instead of submitting a form, a regular action is called 
on the page.  Let’s suppose this action retrieves the previous page from some 
sort of cache and returns that page.  Then that page’s appendToResponse will 
get called and so will the appendToResponse of the  dynamic components being 
shared, which would recompute the condition and save it awaiting a possible 
subsequent takeValuesFromRequest or invokeAction.  Again, this behavior just 
makes the appendToResponse consistent with the 
invokeAction/takeValuesFromRequest phases.

Having this behavior has corrected problems for me.  It is yet to be determined 
whether this will create a problem.  If I find out later that this creates a 
problem I’ll be happy to report back to the group.

But so far, on my tests, it looks like it is okay.

Thanks for all the comments and feedback.

Ricardo

Re: KeyValueCoding is coming for Swift!

2017-03-19 Thread Ricardo Parada

Hi Lars,

I just saw that.  It looks very interesting and I’m still trying to assimilate 
that proposal.

I had created something similar to ERXKey in Swift called Key that you use like 
this:

class Person {
static let firstName = Key(“firstName”)
static let lastName = Key(“lastName”)

var firstName: String 
var lastName: String

…
}

Then build a qualifier like this 
Person.lastName.like(“Para*”).and(Person.age.equals(age).  It looks nicer than 
the ALL-CAPS java version, i.e. Person.LAST_NAME.like(“Para*”).  However, when 
you need key paths this model you have to use the similar to ERXKey’s .dot() 
which doesn’t look very elegant.

Re: ERXWOConditional - where does it get installed?

2017-03-14 Thread Ricardo Parada


I patched both in a test application from within the Application’s 
finishInitialization() method.  After this, then MPVWOConditional is used 
regardless of whether I use WOConditional in the .wod or  in the .html.

   @Override
   public void finishInitialization() {
  super.finishInitialization();

  // Patch conditional components with our own
  ERXPatcher.setClassForName(MPVWOConditional.class, "WOConditional");
  ERXPatcher.setClassForName(MPVWOConditional.class, "ERXWOConditional");
   }

Re: ERXWOConditional - where does it get installed?

2017-03-14 Thread Ricardo Parada

Hi Theodore,

If your .wod is using WOConditional then it uses WOConditional.  You can test 
it quickly by setting a breakpoint in ERXWOConditional’s appendToResponse 
method.  You’ll see that you won’t hit the breakpoint.

Now, if you change it back to  then you’ll hit the breakpoint.

To summarize:
 uses ERXWOConditional.
WOConditional uses WOConditional.

There used to be a property in Wonder to patch WOConditional with 
ERXWOConditional.  I do not see it in the master branch anymore.

Anyways, in your framework principal’s finishInitialization() method you should 
be able to invoke ERXPatcher.setClassForName(ERXWOConditional.class, 
“WOConditional”) to have it patched.  Then you’ll hit the breakpoint whether 
your .wod says WOConditional or ERXWOConditional.

I’m gonna try that and use my MPVWOConditional for both.

Re: ERXWOConditional - where does it get installed?

2017-03-14 Thread Ricardo Parada

Thanks Samuel.  I see that now.

Have others experienced a problem where a form is submitted and then during 
takeValuesFtomTequest a condition that was false when the page was rendered 
becomes true all of a sudden causing some input elements (textfields, pop-up 
list, etc.) to participate in takeValuesFromRequest even though those elements 
were not on the page when the form was submitted? This causes those elements to 
be set to null.   I've ran into such bugs in the past many times.

I have been able to prevent that from happening by using the following code: 


public class MPVWOConditional extends ERXWOConditional {

   protected boolean conditionValue = false;

   public MPVWOConditional(String name, NSDictionary dict, WOElement element) {
  super(name, dict, element);
   }

   @Override
   public void appendToResponse(WOResponse woresponse, WOContext wocontext) {
  // Cache the condition every time the page is being rendered
  conditionValue = 
_condition.booleanValueInComponent(wocontext.component());
  super.appendToResponse(woresponse, wocontext);
   }

   /**
* Returns the value for the condition binding cached during 
appendToResponse.
* This makes the takeValuesFromRequest consistent with the appendToResponse
* preceding it by making sure that input elements that were not present on
* the page at the time the form was submitted do not participate in
* takeValuesFromRequest inadvertently.
*/
@Override
protected boolean conditionInComponent(WOComponent wocomponent) {
   return conditionValue;
}
}

ERXWOConditional - where does it get installed?

2017-03-13 Thread Ricardo Parada

Hi all,

Does anybody know where does ERXWOConditional install to replace WOConditional?

I created an MPVWOConditional which extends ERXWOConditional and fixes a bug 
and want to install it as the one to use for WOConditional. 

I checked in ERXPatches but it does not seem to be getting installed there.  
Does anybody know?

Thanks

ERXQuery Preview

2017-03-11 Thread Ricardo Parada

Hi all,

Over the years, I’ve worked on an class for doing ad hoc queries.  This class 
has gotten better and better.  At first, the API of this class and some 
implementation details were not  ready for public consumption in my opinion.  

However, recently I took the time to polish the code as much as possible and if 
I can get my employer's approval I would like to contribute this code to 
project Wonder which has given us so much in return during the years.  

Here is a preview of its functionality.  Please let me know if you guys think 
this would be a useful contribution.
ERXQuery.java
This class has a fluent API that mimics a select statement:
NSArray> records =
   ERXQuery.create()
  .select (keys)
  .from (entity)
  .where (qualifier)
  .groupBy (groupings)
  .having (havingQualifier)
  .orderBy (sortings)
  .fetch();

Overview
ERXQuery allows you to use EOF constructs (EOQualifiers, EOAttributes, 
EOSortOrdering, EOAttribute names, relationships, etc.) to create queries of 
the form:
SELECT ...
FROM ...
WHERE ...
GROUP BY ...
HAVING ...
ORDER BY ...

Using Ad Hoc Attributes
You may use the ERXAdHocAttributes class to easily create ad hoc attributes to 
use with your query. For example, the code below creates two ad hoc 
EOAttributes. An ad hoc attribute is an EOAttribute that is not physically 
attached to an entity and that has a definition. They are useful for 
aggregating other attributes. The definition of the attribute can reference 
relationships and attributes as shown below.
// Using a single query against the order entity, count the number of
// orders and line items that match the qualifier.
ERXAdHocAttributes attributes = ERXAdHocAttributes.create(orderEntity)
   .add("itemCount", "COUNT(DISTINCT lineItems.lineItemID)", "intNumber")
   .add("orderCount", "COUNT(DISTINCT orderID)", "intNumber");

NSDictionary row =
   ERXQuery.create()
  .select (attributes)
  .from (orderEntity)
  .where (qualifier)
  .fetch()
  .lastObject();

int orderCount = ((Number) row.objectForKey("orderCount")).intValue();
int itemCount = ((Number) row.objectForKey("itemCount")).intValue();

Fetching into a Custom Record Class
You can also fetch using a custom class of your choice, i.e. Foo, as shown 
below:
// Using java >= 8 is easy with a lambda expression
NSArray objs = query.fetch(editingContext, (ec, row) -> new Foo(ec, row));
   

// Using java < 8 you must provide a RecordConstructor 
ERXQuery.RecordConstructor recordConstructor =
   new ERXQuery.RecordConstructor {
   @Override
   public Foo constructRecord(EOEditingContext ec, NSMutableDictionary row) 
{
  return new Foo(ec, row);
   }
   };

NSArray objs = query.fetch(editingContext, recordConstructor);

Does NSUndoManager work?

2016-10-08 Thread Ricardo Parada

Hi All,

I have not used the undo manager since the Objective-C days I think.  I tried 
to use it recently but I get an exception. Has anybody used it successfully?  
For example:

myEO.editingContext().undoManager().beginUndoGrouping();
myEO.setFoo(foo);
myEO.editingContext().undoManager().undo();

This code generates this exception:

java.lang.IllegalStateException: undo: undo manager is in invalid state, undo 
was called with too many nested undo groups


I thought there was something wrong with the undo manager in that editing 
context.  So I tried creating a new NSUndoManager() and calling 
setUndoManager(myUndoManager) on the editing context.  Same result.

I searched on google for that exception and several things came up but nothing 
that could tell me why it happens.

Thanks,
Ricardo Parada

Re: IllegalStateException: "...EOEditingContext has already been disposed"

2016-10-01 Thread Ricardo Parada

Hi Paul,

I don’t know if this is what is going on in your case but I once had a problem 
where an EO was inserted into an editing context, then the editing context was 
reverted, i.e. ec.revert().  Then the app has a variable holding on to a 
reference to the EO.  However, that EO’s editing context became null, i.e. 
eo.editingContext() == null after the revert and it was causing a problem.

Re: Cannot obtain globalId for an object which...

2016-09-21 Thread Ricardo Parada

Hi Chuck,

Once you said it was transactional I suspected something was getting EOF in 
this state and I discovered an exception that once I took care of it seems to 
have taken care of this one as well.  

I did not go into enough detail to fully understand the dynamics of what was 
going on though.  We have a transaction extender attached to the main editing 
context which prevents EOF from committing the transaction.  For example, we do 
this to generate a SELECT FOR UPDATE NOWAIT to lock a record and hold on to 
that lock until we do saveChanges() on that editing context which commits the 
transaction.  While we are holding this lock we local instance EOs into a peer 
editing context.  We do a lot of processing with our EOs in this peer editing 
context but changes here are not supposed to be saved to the database.  
However, some piece of code was trying to saveChanges() and generated an EOF 
error about unable to increment snapshot count.  I simply corrected this code 
so it does not call saveChanges() in this editing context and the other problem 
magically went away.

Thanks for the help.

Re: Cannot obtain globalId for an object which...

2016-09-20 Thread Ricardo Parada

Hi Chuck,

I followed the steps of the code and I noticed that the object containing the 
to-many relationship in question is being local instanced in a peer editing 
context. The to-many is still an array fault which has not been triggered. 

Then when the object in the original context has its to-many triggered, i.e.  
by calling:

analysis.groupings().count();

Where analysis is the EO and groupings() is the to-many then the exception is 
generated. 

It appears to have that if I trigger the to-many early on then the exception is 
avoided. 

Anyways, I will experiment a little bit more with the problem and report back. 
I don't recall seeing something like this before and I local instance objects 
from one editing context to another all the time. 

Thanks

Re: Code review for refreshToOneRelationshipWithKey

I just tried the ERJGroupsSynchronizer and it worked. I was worried that there 
might be a delay in the synchronization such that the thread updating the user 
interface might not pick up the change on time and would display the new info. 
I'm curious how it does it and whether it is possible for the change not to get 
to the user interface on time. 

Thanks Paul and Ted.

Re: Code review for refreshToOneRelationshipWithKey

2016-09-04 Thread Ricardo Parada

Thank you Ted for that link. I was actually present at that presentation. 

At that time I did not have a need for synchronization between EOF stacks.  I 
was also overwhelmed by the xml configuration file but now that I hear it again 
it sounds like there is no need to mess with it. I like that he said that he 
had used that for years and was never able to deadlock it during extensive 
testing and that the caches were accurate. That is good. 

I did try to use the ERXObjectStoreCoordinatorPool in the past. However for our 
background threads that are spawned to do work I wanted to make sure that they 
had a separate pool so that  they did not interfere with the foreground threads 
processing requests from the user. I also wanted connections to the database 
closed when an object store coordinator was returned to the pool by all the 
thread(s) using it. That created a better experience and conserved resources. 

The synchronization though, it does look like it will solve my problem. I 
definitely want to play with that. I assume that you are using the second 
synchronizer based on JBoss stuff, right? Mike mentioned that he would not use 
the first one for production. 

Thank you.

Re: Code review for refreshToOneRelationshipWithKey

2016-09-03 Thread Ricardo Parada

Thanks Aaron, your suggestion is working well.  It is analogous to a "git 
rebase” ;-)  I feel better with this code.

I did find that the technique did not work for to-many relationships, but added 
a bit of code towards the end of the method to refresh the to-many 
relationships using Wonder:

/**
 * Core method to refresh properties selectively with data from the 
database. The
 * properties can be attributes, to-one or to-many relationships.
 */
public void refreshProperties(NSArray keys) {
NSDictionary changes = changesFromCommittedSnapshot();

// Discard changes to the properties that we're about to refresh if any
NSMutableDictionary changesToKeepAfterRefresh = 
changes.mutableClone();
changesToKeepAfterRefresh.removeObjectsForKeys(keys);

// Now fetch the receiver refreshing it with changes from database
EOEntity entity = entity();
EOFetchSpecification fs = new EOFetchSpecification(entity.name(), 
primaryKeyQualifier(), null);
fs.setRefreshesRefetchedObjects(true);
editingContext().objectsWithFetchSpecification(fs);

// Now re-apply the changes we want to keep
if (changesToKeepAfterRefresh.count() > 0) {
takeValuesFromDictionary(changesToKeepAfterRefresh);
}

// The above will not refresh to-many relationships so do something a 
bit
// more drastic to refresh the to-many relationships.
for (String key : keys) {
EORelationship relationship = entity.relationshipNamed(key);
if (relationship.isToMany()) {
ERXEOControlUtilities.clearSnapshotForRelationshipNamed(this, 
key);
}
}
}

And some convenient methods to go with it too:

/**
 * Convenience method to refresh properties selectively with data from the 
database.
 * The properties can be attributes, to-one or to-many relationships.
 */
public void refreshProperties(String... keys) {
NSArray keysArray = new NSArray(keys);
refreshProperties(keysArray);
}

/**
 * Convenience method to refresh properties selectively with data from the 
database.
 * The properties can be attributes, to-one or to-many relationships.
 */
public void refreshProperties(ERXKey... erxKeys) {
NSMutableArray keys = new 
NSMutableArray(erxKeys.length);
for (ERXKey erxKey : erxKeys) {
keys.add(erxKey.key());
}
refreshProperties(keys);
}

2016-09-03 Thread Ricardo Parada

Thanks Aaron that is a great suggestion. I will give that a try as it does not 
require messing with snapshots and getting down to lower layers of EOF. I think 
I would feel better with an implementation like that. 

As for ERXJGroupsSynchronizer, I am not familiar with that and can't really 
tell how to use it. It also sounds like it might replace edits in progress. 
Thanks Ted. I had heard of this class before but did not know it was being used 
successfully. It is good to know.

Code review for refreshToOneRelationshipWithKey

2016-09-03 Thread Ricardo Parada

Hi all,

I have a need to refresh the to-one relationship of an object, so that if 
someone in another app or perhaps in a different EOF stack within the same app 
has updated the to-one to point to a different object then I want my EO’s to 
one to point to the correct EO.  I do not want to invalidate the source EO or 
refetch it because it may have edits in progress.

I searched in Wonder but I was not able to find anything that does this.  I 
came up with the code below last night and it seems to work well so far.  

Since this is an advanced EOF topic I thought I should share it to see if 
anybody wants to code review it, play with it and provide comments on 
correctness / recommendations / feedback.  

This code uses a primaryKeyQualifier() method in my EO which is practically the 
same as the identityQualifier() concept discussed by Aaron Rosenzweig in an 
email thread in May of this year.

Thanks in advance for any help.


@SuppressWarnings("rawtypes")
public void refreshToOneRelationshipWithKey(String toOneName) {
EOEditingContext ec = editingContext();
EOEntity entity = entity();
EORelationship toOne = entity.relationshipNamed(toOneName);
String foreignKeyName = toOne.sourceAttributes().lastObject().name();
EOFetchSpecification fs = new EOFetchSpecification(entity.name(), 
primaryKeyQualifier(), null);
fs.setRawRowKeyPaths(new NSArray(foreignKeyName));
@SuppressWarnings("unchecked")
NSDictionary dict = (NSDictionary) 
ec.objectsWithFetchSpecification(fs).lastObject();
Object newForeignKeyValue = dict.allValues().lastObject();
EOGlobalID gid = globalID();
EOModel model = entity.model();
EODatabaseContext dbc = 
EODatabaseContext.registeredDatabaseContextForModel(model, ec);
EODatabase database = dbc.database();
EOObjectStoreCoordinator osc = (EOObjectStoreCoordinator) 
ec.rootObjectStore();
osc.lock();
try {
NSDictionary snapshot = database.snapshotForGlobalID(gid);
Object currentForeignKeyValue = 
snapshot.objectForKey(foreignKeyName);
// We don't need to check for null as currentForeignKeyValue and 
newForeignKeyValue
// use NSKeyValueCoding.NullValue to represent null.
if (currentForeignKeyValue.equals(newForeignKeyValue) == false) {
NSMutableDictionary newSnapshot = snapshot.mutableClone();
newSnapshot.takeValueForKey(newForeignKeyValue, foreignKeyName);

database.recordSnapshotForGlobalID(newSnapshot.immutableClone(), gid);
Object toOneValue = NSKeyValueCoding.NullValue;
if (newForeignKeyValue != NSKeyValueCoding.NullValue) {
EOKeyGlobalID toOneGID = 
ERXEOGlobalIDUtilities.createGlobalID(toOne.destinationEntity().name(), new 
Object[] {newForeignKeyValue});
toOneValue = ec.faultForGlobalID(toOneGID, ec);
}
// Update __originalSnapshot() and EO so that 
changesFromCommittedSnapshot()
// does not think that the object has changed.
NSDictionary originalSnapshot = __originalSnapshot();
NSMutableDictionary newOriginalSnapshot = 
originalSnapshot.mutableClone();
newOriginalSnapshot.setObjectForKey(toOneValue, toOneName);
__setOriginalSnapshot(newOriginalSnapshot.immutableClone());
if (toOneValue == NSKeyValueCoding.NullValue) {
takeStoredValueForKey(null, toOneName);
} else {
takeStoredValueForKey(toOneValue, toOneName);
}
}
} finally {
osc.unlock();
}
}

public EOQualifier primaryKeyQualifier() {
NSDictionary pkDict = primaryKeyDictionary(false /* 
inTransaction */);
EOEntity entity = entity();
return entity.qualifierForPrimaryKey(pkDict);

Re: Is this a deadlock?

2016-09-02 Thread Ricardo Parada

Thank you. 

Is there a way to know what thread is holding a lock?

If a thread did some database activity and did not release a lock would it show 
anywhere?  I noticed this at the end of the stack trace dump: 

EC info:
Currently 0 active ECs : {})No open editing contexts (of 0)OSC info:
0 active ObjectStoreCoordinators : {})No open ObjectStoreCoordinator (of 0)

Would it show here?

Is this a deadlock?

2016-09-02 Thread Ricardo Parada

Hi all,

In a recent release one of our apps started to get stuck.  This is the stack 
trace of all threads in the app.  I ordered the threads to show the ones that I 
think are in a deadlock: WorkerThread2, Timer-0 and BackgroundTask-63.  How can 
I tell if the apps are in a deadlock by looking at the stack trace?  Thanks in 
advance for any help.

Re: Going Server-side with Swift Open Source

2016-06-16 Thread Ricardo Parada

Hi -

I’ve been following Swift’s evolution in the swift-evolution mailing list.  As 
it exists today on the server is still lacking some key features needed to 
implement key-value-coding.

There is a MIrror class that allows you to see the property names of a class 
(or even a struct) and get the value of each property.  But it only works for 
properties.  It does not work for methods in your objects.  In addition, it is 
read-only, i.e. you can get the values but you cannot set properties.

Hopefully by Swift 4 or 5 those features will arrive.  But they are not there 
in Swift 3.

On Apple platforms they are able to use CoreData because they are leveraging 
Objective-C run-time.  However, the Objective-C run-time is not available on 
the server.

Ricardo Parada

Oops, I meant one Silver sponsorship. 

By the way, we are one of those who are still on an old version of Wonder but 
we will be moving to the latest version.  After that I am hoping to keep it up

I signed up my employer for one Bronze sponsorship. Sometimes we take things 
for granted. We benefit a lot for Wonder. 

I really appreciate everything you do Pascal. 

I really love WebObjects, Wonder, the wocommunity web site and this community 
of very experienced and talented developers. 

I will not be attending this year because things did not align right for me 
this time. I was really looking forward to going. I hope I have better luck 
next year. A coworker will be attending though. And I look forward to seeing

Re: WebObjects officially declared dead by Apple

2016-05-04 Thread Ricardo Parada

Hi Hugi,

I should probably bite the bullet too and get some hands on experience and find 
out what it takes to transition.

I think I would start by changing our base EO class to extend the Cayenne data 
object instead of ERXGenericRecord.  All of a sudden my EOs would be missing a 
lot of the methods from ERXGenericRecord which I could try to reimplement using 
the Cayenne API.  

I have some questions, what would happen to KVC stuff?  In the mean time I 
could use NSKeyValueCoding or Q’s open source implementation I guess.  
NSArrays, NSMutableArrays, and dictionaries would have to be replaced with java 
equivalents I’m guessing.

Can we generate cayenne object models from eomodels?

I have other maybe more advanced questions regarding the feature set of Cayenne 
that we may require in order to transition:

1. Is it possible to have one object model connect to database A, and another 
object model connect to database B?  For example, we run a query against a 
reporting database, then we output some results into a production database.

2. I have an ad hoc query framework that relies on EOSQLExpression to generate 
SQL from fetch specifications and qualifiers.  You specify the attributes to 
fetch and you provide additional attributes to build  a GROUP BY clause, and a 
qualifier for a HAVING clause.  You can also define aggregate attributes (i.e. 
SUM(), AVG(), MAX(), MIN(), roll your own here), on the fly by cloning the 
original entity into a new one that has the aggregate attributes added, which 
are nothing more than flattened attributes added to the new entity.  This 
enables the ad hoc query framework and we use it extensively for reports.

3. Our tables in the database are very large and are partitioned by client id.  
Each client may have large volumes of data (millions) in tables in the 
database.  A client logs in and usually all queries against a main table have a 
clientID = x.  We have our own concrete subclass of EOSQLExpression which 
optimizes the SQL generated by adding automatically clientID = x when joining 
into other child tables that have the clientID attribute.  It is a very elegant 
solution and it amazes me that something like EOF that was created such a long 
time ago enables all these things for us.  We can always get down to the level 
we need and customize its behavior.

4. Can the Cayenne equivalent of EOEntity, EOAttribute and EORelationship have 
user info in them?

5. Do we have the equivalent of ERExistsQualifier that works in memory and 
database?

Thanks

I remembered Ariba and the time he spent there too and it's part of why I was

Also I can't imagine working on the server side without something like

I think that is great for new projects. I was thinking of something API

make the transition less traumatic. :-)

If you think about it, one of the reasons they are bringing Swift to Linux is 
because they want a cool language on the server as well as on the client and 
leverage the code and libraries on both. 

At some point these developers need an ORM framework. Either Apple or someone 
else will do it in pure Swift without requiring the Objective-C run-time. 
Possibly a future Core Data. Then they'll need a templating request handling 
framework like WebObjects for Swift. And a REST framework. Let's bug Federighi 
with emails about bringing this back. :-)

Anyways, putting all this day dreaming aside I think we need a clean room 
implementation of EOF as it had been described before.  I have worked at al 
levels in EOF and I feel this would be possible until I realize that I am 
married with four kids and a full time job that leaves me with no spare time 
left to work on things like this.   :-)

Was the idea of a clean room implementation of EOF abandoned?

I Wonder if Craig Federighi has any love for WebObjects in his heart. I mean he 
was very involved with EOF and WebObjects.  Perhaps a Swifty WebObjects for 
Linux in the distant future using Swift 4's property behaviors to implement 
object/array faults.

There’s also a property for that.  I believe you can use:

er.extensions.ERXEC.editingContextClassName=your.package.YourEC

to have the default factory use that class when creating EC instances via 
ERXEC.newEditingContext().

 Hello there,

 is there a trick to “undelete” an object in editing context?

 Before saveChanges, I go through ec.deletedObjects(), and in some very 
 special cases, I might find that an object should NOT be deleted. Just 
 like it has never been added to deletedObjects at all.

 I've tried to insertObject it immediately; that works all right for the 
 object itself, but still removes its owned :1 relationships, which is also 
 quite wrong.

 Is there a way to do it right?

 Note: if there was a way to mark specific objects as read-only (never to 
 be deleted, never to be updated), it would be even better; but I've tried 
 to override isReadOnly, and it does not seem to be even called from 
 saveChanges. I can't make R/O the whole entity: it applies to only some of 
 its objects. I can't throw from validateForDelete either: I don't want 
 saveChanges to fail. I need it to work all right with all the other 
 objects, just not deleting a couple of special ones (nor their owning 
 relationships).

 Thanks,
 OC

At my employer we are still on HTML and Wonder's Ajax.  No plans to make any

I heard Microsoft's Internet Explorer is suppose to die today though.

Re: when is derived column resolved

2016-01-12 Thread Ricardo Parada

I rarely ever use them. 

When they have been used it was for constructing queries that use the derived 
column when building reports.It avoids having to bring in the objects into 
memory and compute the value to see if they meet the qualifier. However if the 
qualifier can be expressed using the non derived attributes I take that route 
instead.

Re: wotaskd reliability

2015-12-12 Thread Ricardo Parada

Hi Pascal

Containers sound like a great topic for a WOWODC presentation. I would love to 
learn about how to use them for example to have a WO environment with java, 
MySQL, wotaskd / JavaMonitor. Is that the kind of stuff they would be used for? 
And how do I create a container and use it with a server.

 Where do I start? :) In no particular order:
 
 Number of knowledgeable administrators. 
 Server software packages (openstack, docker, etc)
 Targeted at power users (doesn’t F up /usr/local, has bash completions,

 Uptime.
 Virtualization.

Re: Vector graphics in Flying Saucer / ERPDFWrapper

2015-12-01 Thread Ricardo Parada

Thank you Johann, that should get me going.  The MANIFEST in the jar files says 
that they were built with java 1.7.0_79.  I am going to try to find out if they 
are compatible with java 5, but based on the manifest it would be safer to keep 
this only in master as it may require > java 5.

Thanks

Re: Vector graphics in Flying Saucer / ERPDFWrapper

Hi all,

I was trying to create a pull request to remove core-rederer-20101006.jar from 
ERPDFGeneration and add flying-saucer-core-9.0.8.jar and 
flying-saucer-pdf-9.0.8.jar.

However the fork I have of wonder on my github account is really old and I’m 
confused how to go about doing this.  I’m not even sure what branch to put it 
on.  My fork of wonder only has master, integration, and Wonder_5_0_0_Legacy.  
I was expecting to see master, wonder_5, wonder_6 and wonder_7.

Is there any documentation on how to go about submitting a pull request for 
wonder? 

Thanks
Ricardo

Thank you Timo and Samuel for your responses. 

The easiest for me was to just update the flying saucer library to 9.0.8 as 
Timo suggested. I can now use the .pdf logo with vector graphics. The logo now 
looks beautiful on the Retina display.

Vector graphics in Flying Saucer / ERPDFWrapper

2015-11-17 Thread Ricardo Parada

Hi all,

We use ERPDFWrapper to generate PDF from a WOComponent.  It comes out 
beautiful.  

One of our components includes a logo using the  html tag and the logo is 
usually a .gif or .jpg.  However, I would like to use vector graphics.  We took 
a .eps file and converted it to .pdf in Photoshop.  The resulting image scales 
beautifully to any size.  When I try to use the .pdf I get 
java.lang.ClassCastException: org.xhtmlrenderer.pdf.PDFAsImage cannot be cast 
to org.xhtmlrenderer.pdf.ITextFSImage.  

Has anybody been able to use vector graphics in ERPDFWrapper?

Thanks

Re: Driver and Implementation of NoSQL

2015-10-28 Thread Ricardo Parada

I have to look it up and see what I can share. I have it in a git branch in a 
local repository. I will be getting back to this in the future as we will 
probably move forward with this. We have some tables that are huge and we want 
to start using Mongo DB to store that information. The tables outgrew the 
limits of an integer for the primary key years ago. 

The object graph that I deal with is similar to a document. The parent owns the 
children. It only has one reference to a user object which it does not own. 

I also had special requirements. I needed to still be able to read existing 
data from our relational oracle database. So the model is really mapped to 
oracle and can fetch from it. Then I wrote code to save to mongo for new data 
generated. And I can also fetch from mongo. 

Anyways in the (near I hope) future I'll be getting back to this project.

Re: Transactions

2015-10-28 Thread Ricardo Parada

The way I have done this is by writing an object that sets up itself as the 
delegate of the adaptor context and the editing context. 

The object implements adaptorContextShouldCommit(adaptorContext) and returns a 
flag shouldCommit which is initially false. 

This keeps the transaction open while you call your stored procedures or 
execute bulk updates or whatever. Then the object implements 
editingContextWillSaveChanges(editingContext) and simply sets the shouldCommit 
flag to true.  In other her words, calling saveChanges on the editing context 
will call that delegate which will set the flag and then when the 
adaptorContextShouldCommit(adaptorContext) delegate method gets called again, 
this time it will return true because the flag has been set and the transaction 
will commit. 

The flow is like the this:

1. Create delegate object and set it up as the delegate of your editing context 
and adaptor context.  EOUtilities has databaseContextForModelNamed() that may 
come in handy. 

2. Create and update your EOs. Don't save changes yet. 

3. Call your stored procedures or execute special sql or bulk update, etc. the 
transaction will not commit and will remain open. 

4. Update and create more EOs if you want. 

5. Call saveChanges() in your editing context. This time the transaction will 
commit. 

That is what I have done and it works.

Re: Driver and Implementation of NoSQL

2015-10-27 Thread Ricardo Parada

Hi Gino,

Let me know if you hear of any. 

I can tell you about an attempt / workaround I did. I inserted my enterprise 
objects (EOs) into an editing context. Then I used some of the classes in the 
ERRest framework to serialize my object graph of enterprise objects into JSON. 
Then I used the Mongo DB java driver to save the JSON to the Mongo database. 

Then to retrieve the objects I reverse the process. Use the Mongo DB Java 
driver to retrieve the JSON and the ERRest classes to rehydrate the objects 
into an editing context. 

Ricardo

Apps launch fine from the command line but not from JavaMonitor - CentOS 6.5

2015-10-25 Thread Ricardo Parada


Is anybody familiary deploying on CentOS 6.5.  I just want to get the basic 
stuff working.  I have a simple WOnder app (TestApp.woa) with all frameworks 
embedded.  I have the apache, the WebObjects http adaptor, JavaMonitor and 
wotaskd running.

In a nutshell, the app runs just fine from the command line but it won’t start 
from JavaMonitor. The TestApp keeps dying.  It does not even get to log 
anything under /opt/Local/Library/WebObjects/Logs.  It is as if JavaMonitor did 
not even try to run it.

On the other hand, if I run the application from the command line I can direct 
connect to it.  I’ve spent many hours and I cannot figure it out.  

If I go to a static file configuration by changing my 
/etc/httpd/conf.d/webobjects.conf file as follows:

LoadModule WebObjects_modulemodules/mod_WebObjects.so
WebObjectsDocumentRoot /var/www/html
WebObjectsAlias /apps/WebObjects

# Commented out this because I cannot get apps launched from 
# JavaMonitor.  
#WebObjectsConfig http://localhost:1085 10

# File configuration works fine
WebObjectsConfig file:///opt/Local/Library/WebObjects/Configuration/Apps.xml 10

WebObjectsLog /tmp/WebObjects.log Debug

My /opt/Local/Library/WebObjects/Configuration/Apps.xml file is as follows:








I then restart apache and run my TestApp from the command line:

# cd /opt/Local/Library/WebObjects/Applications/TestApp.woa/
# ./TestApp -WOPort 2001

After this I can connect through the web server, i.e. 
http://host/apps/WebObjects/TestApp or using direct connect, i.e. 
http://host:2001.

Please let me know if you have any suggestions on what to try to help debug the 
problem.

Re: Help Installing Deployment environment on CentOS 6.5

2015-10-24 Thread Ricardo Parada

I proceeded to install wotaskd, womonitor and woadaptor my creating the repo by 
hand and replacing the $releasever with the number 6.
They seem to install.  However, when I touched /tmp/logWebObjects and restarted 
apace I noticed that the following was logged:

[root@li1170-129 ~]# tail -f /tmp/WebObjects.log
Debug:  new translate: /
Debug:  translate - DECLINED: /

Debug: WebObjects_handler declined! /index.html

Does anybody know what that means?

Thanks in advance

Help Installing Deployment environment on CentOS 6.5

2015-10-24 Thread Ricardo Parada

Hi all,

I’m following the instructions on the wiki to setup the deployment environment 
on CentOS, etc.  i.e. 
https://wiki.wocommunity.org/pages/viewpage.action?pageId=8585219&src=search

However, this step:

sudo curl -o /etc/yum.repos.d/wocommunity.repo 
https://raw.github.com/wocommunity/wonder/master/Utilities/Linux/wocommunity.repo

Does not seem to work for me.  I don’t know why it’s not able to read the repo 
from the url.  If I just do curl I get nothing.  However, using Safari I was 
able to get the contents of that url which looks like this:

[wocommunity]
name=WOCommunity
baseurl=http://packages.wocommunity.org/CentOS/$releasever/
enabled=1
gpgcheck=0
#gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6-LocalRepo
protect=0

Should I create the /etc/yum.repos.d/wocommunity.repo by hand and replae 
$releasever with the number 6 then?

Thank you

Re: WOLips and ant editor for build.xml

2015-10-21 Thread Ricardo Parada

I figured out what was wrong. I simply went to the Window menu and reset the 
perspective.  After resetting the perspective the outline view that I was 
missing magically appeared. 

The ant editor can be associated with the build.xml file by going to the 
Preferences under file associations. 

I hope this helps someone on the list.

WOLips and ant editor for build.xml

2015-10-20 Thread Ricardo Parada

Hi all,

In one of the 2009 WOWODC videos I saw Pascal editing a build.xml in Eclipse 
where he can see the values of properties as he hovers the mouse over the 
property name. He was also able to see the names of the targets in the 
build.xml file in an outline view on the right hand side and he was able to 
right click on a target and run ant on it. 

How do I get the same?  I was able to tell Eclipse to use the ant Editor when 
opening the build.xml. That gets me half the functionality where I can see the 
values for the properties. I am still missing the outline view with the targets 
and be able to right click on them. 

Does anybody know?

Thank you.

Re: Yosemite deployment problem with MySQL (Stavros Panidis)

2015-10-17 Thread Ricardo Parada

I remember MySQL having restrictions that deny access to a user depending on 
what host it is connecting from.   Do the following: 

MySQL> USE mysql;
MySQL> SELECT user, host FROM user;
