Re: [EXTERNAL] Re: Java upgrade question

[Morris, Mark via Webobjects-dev]

Hi Paul,

Thanks, that’s great to hear! There was some concern expressed a while back 
that it might be impossible to move past Java 8 because of a change to the way 
classes are loaded. I’m definitely glad that turned out not to be the case!

Take care,
Mark

I know at least at one point there was an issue migrating past Java 8, due to

Plenty of people have moved beyond Java 8. We've been using Java 21 since soon 
after it was released. About the only thing you'll need to do is add some JVM 
options in 
build.properties<https://urldefense.com/v3/__http:/build.properties__;!!MfzFaTml5A!kVqrmx58oqFRWdQNqzkgLBMqSjN9BNTffYpBV39CThLDnVveU0G69UQ1s-GThu7W_bSsufTI2G1LRfZyhX0cDO0ULtrRVWo$>,
 such as:

jvmOptions=--add-exports java.base/sun.security.action=ALL-UNNAMED 
--add-exports java.base/sun.util.calendar=ALL-UNNAMED

I'm struggling to think of much else that was required. It was certainly an 
easier transition than I thought it was going to be.

Re: [EXTERNAL] Latest working Eclipse/WOLips

[Morris, Mark via Webobjects-dev]

Hi Riccardo,

I'm using Eclipse 2020-12, but I haven't heard anyone complaining about issues 
with the new 2021 release. For either one, you need to make sure to point to 
the most recent WOLips. You can find general instructions (referencing slightly 
older versions) at: 
https://wiki.wocommunity.org/display/WEB/Project+Wonder+Installation

Also, note that this mailing list has been unreliable lately, so there's now a 
new, community-maintained list. See the info at: 
https://wiki.wocommunity.org/display/WEB/Home

Hope this helps!

Re: [EXTERNAL] Re: Trouble installing WOLips

[Morris, Mark via Webobjects-dev]

Hi Wolfy,

Thank you for the suggestions! I changed Eclipse to point to the URL you 
suggested, but I get the same error message.

Also, this is a brand new machine, so I originally tried it with the version of 
Java 8 supplied by Apple. When that didn’t work, I installed the current Zulu 
OpenJDK version of Java 8, and updated the eclipse.ini file to make sure 
Eclipse points to that:


-vm 
/Library/Java/JavaVirtualMachines/zulu-8.jdk/Contents/Home/jre/lib/server/libjvm.dylib

However, I still got the same error.

Still stymied at the moment.

Mark

Re: Multiple timezones

[Morris, Mark via Webobjects-dev]

Hi Michael,

I’d recommend storing only UTC. We grab the client’s timezone from the browser 
using javascript and it gets sent back in the very next RR loop after they 
visit the site, so for the rest of the session we can display any time data in 
their local timezone if necessary.

Hope this helps!

In that case, I’d use apache http client, which has all I need. I can even put

Re: LoadBalancer

Hi André,

If in reality the situation is as simple as your example, perhaps you could 
just create a separate single instance with a distinct name for your “defined 
instance", and use that for requests that require it. We do something like that 
for certain special situations.

You can try  the subclass way. You  could override appendToResponse in your

After I have created the subclass, the Captcha was not longer visible. I

will check that again, or I'll go the longer way: fixing the bug within
the framework. There are more problems within the framework, it runs
only with Java 1.5.

Re: On the future of WO (here we go again)

[Morris, Mark]

Thanks for the offer! Unfortunately I won’t be able to make the trip for WODay. 
I would have loved to be there, and would be really interested in doing a 
deeper dive into understanding Cayenne.

Also, the trip would have been nostalgic for me, since I lived for a year in 
the Frankfurt area (Königstein im Taunus), 40 years ago now.

Mark

Hi Mark,

In 2017, Hugi and I converted a large project (>800.000 lines) from EOF to 
Cayenne, within a few months. Had parallel branches for a while and then 
switched in production, never looked back. Cayenne is similar enough that most 
of the work is either boilerplate conversion or actually making use of the 
newly-gained benefits. Very few hard problems encountered, and all solved.

Let's have a talk in Frankfurt about what your EOF specifics actually are.

Hi all.
In preparation for the coming WODay in Frankfurt, I'd love it if you'd be open 
to having a discussion on the status and future of WO, so we can enter the 
coming work prepared.

I'd like to begin by sharing my own thoughts on the matter, based on my current 
stack and experience. It's a rehash of something I posted to our Slack 
yesterday, may sound revolutionary and will no doubt be controversial, but I 
think some outside-the-box thinking is required at this time. This is lengthy, 
sorry about that…

--

In the past few years I've been working towards minimising the use and effect 
of WO/Wonder on my stack, so when and if The Time comes, I and my customers 
have a migration path forward. Among the things I've done is move from EOF to 
Cayenne and from Ant to Maven (to make using 3rd party jars, including Cayenne 
easier), both of which have turned out to have been very happy decisions which 
I wholeheartedly recommend, regardless of anything else you do.

I love working with my WO/Cayenne stack, which is currently only "polluted" by 
the following frameworks:

-- WO:
* JavaFoundation (indirectly through WO, I never use foundation classes in my 
code unless absolutely required by WO)
* JavaWebObjects

-- Wonder (I consider Wonder "polluted" since it depends on WO/EOF)
* ERExtensions (only the WO stuff, not the EOF stuff)
• Ajax
• WOOgnl (indirectly for parsing Wonder-style inline templates)
…and of course then there's the deployment stuff (JavaMonitor,wotaskd, 
adaptors).

Given this, here's my proposal for a way forward:
* We abandon EOF (and, in fact, any ORM—this is not meant to be a full stack 
effort, initially at least)
* We re-implement JavaWebObjects as required (and the absolutely necessary 
parts of JavaFoundation, such as KVC and NSBundle) as a single framework
* We separate the necessary WO stuff from the EOF/D2W stuff in Wonder (as well 
as other totally unrelated things like mail sending frameworks, other utility 
frameworks and "useful applications") and include it in our re-implementation
* We create a fork of WOLips that knows how to live within the New Universe
* We rule the world

Ideally, what we end with is Just a Web Framework™ with IDE integration (and 
nothing else) that can serve as a basis for future development. While 
re-implementing WO may sound like a huge undertaking, I actually think it's 
smaller than rewriting all of my solutions that depend on it. This probably 
applies to more of you.

Now, looking at my own stack I know this proposal might sound a bit 
self-serving, but I'd like to hear other opinions. I believe it's a realistic 
way forward with (comparatively) minimal development effort. Turns out that WOF 
itself is the only part of the WO/Wonder stack that I really just don't want to 
live without.

This is something I'd like to do, and if anyone likes the idea and is willing 
to participate, I'm confident we can make this work! Doing stuff alone sucks.

WOLips and dark mode

[Morris, Mark]

Hello! So after reading the experiences of others on the list, I went ahead and 
successfully updated to Eclipse 2018-12, and it was as painless as could be.

I was finally trying out Eclipse’s dark mode, and had a couple of questions. 
The rest of the UI seemed to pick reasonable defaults for font and background 
colors, but WOD and HTML fonts are difficult to see. Also, the WO Outline view 
didn’t switch at all, but kept its white background. Is this something that 
WOLips needs to be updated to support, or do I need to set up custom settings?

Thanks!
Mark

Re: Advice on whether to upgrade Eclipse / WOLips from Eclipse Mars 4.5

[Morris, Mark]

I’m on Eclipse 4.6 and it’s working fine, but a few of my coworkers are on 
Eclipse 4.7 and are very happy with it. (We all use WOLips.)

Coincidentally I just downloaded Eclipse 2018-12 yesterday to give it a try 
sometime in the next week or so. Anyone try this yet?

Hi John, I’m on Eclipse 4.6 and it is ok. I have not tried 4.7 with WO.

Newer Eclipse can sometimes bring better debugging and general Java goodness 
but other than that…

If you are reasonably happy, I wouldn’t switch.

I guess for giggles and grins you could try out 4.7 and see how it goes.

ERAttachment / multiple file upload questions

[Morris, Mark]

Hello!

We’d like to add multiple file upload capabilities to our app. Looking around, 
it seems Wonder has an ERDragAndDropUpload component that does that.

However, it looks like it’s dependent on also using ERAttachment. We’ve been 
using our own Attachment class since before ERAttachment existed, so I’m not 
sure how it could be integrated at this point. On top of that, it looks like 
some of the documentation for ERAttachment is currently unavailable. (I can’t 
get to the Overview or the tutorial movie linked from 
).

So I guess I have a multiple part question. Is ERDragAndDropUpload the best way 
to go nowadays for implementing drag and drop multiple file uploads? If so, is 
it, or maybe ERAttachment, flexible enough that I can get the uploaded files 
and save them in our own Attachment class? Finally, if that might be possible, 
are there live links out there to some of the documentation?

Thanks in advance!

Regards,
Mark

Re: Enterprise objects stored in JSON or byte

[Morris, Mark]

Hi Mark,

This sounds similar to something we do. We create entities on demand that are 
used for reporting purposes, where data is grouped and rolled up from our 
“real” persistent entities. I think there are some differences in what you’re 
looking at, though.

Perhaps instead of using NSDictionary, you could make use of all the goodness 
in the EOF stack and use ERXGenericRecords. You would have to make sure that 
the top-level editing context associated with these does not actually save 
anywhere.

Good luck!
Mark

Re: EOEnterpriseObjectClazz with interface

[Morris, Mark]

Hi Henrique,

That’s cool, I hadn’t considered how an enum and an interface could work 
together like that. ☺

In my particular case this could work. Another idea I had is using the 
EOEntity’s userInfo dictionary to store the relevant distinguishing 
information. But it doesn’t seem as clean as just adding the method to the 
interface, from an object-oriented / business logic encapsulation point of 
view. It seemed like that capability was implied by the class comments of 
EOEnterpriseObjectClazz, but perhaps it doesn’t quite go that far.

Thanks!

Subject: Re: EOEnterpriseObjectClazz with interface

Hey Mark,

Even if Java allowed you to override static methods of an interface, you would 
still have problems to discover the classes that implement them in runtime. In 
the end, it doesn't matter if you remember to implement the static method in 
your subclass if you forget to call it somewhere else.

For this reason, the answer to your question must have two characteristics:

1. Subclasses of WorkflowRoutable must implement a method to provide useful 
information.

2. WorkflowRoutable types must be easily discoverable at runtime.

It turns out there's a Java construct that can help you in this case. You could 
create an enum of WorkflowRoutableTypes and require every subclass of 
WorkflowRoutable to implement a method that returns its type.The code I imagine 
looks like this:

interface WorkflowRoutable {
public static enum WorkflowRoutableType {
WORKFLOW_1 {
@Override
public String usefulInformation() {
return "useful information for workflow routable 1";
}
},
WORKFLOW_2 {
@Override
public String usefulInformation() {
return "useful information for workflow routable 2";
}
};

public abstract String usefulInformation();
}

...

/**
 * Returns the type of this WorkflowRoutable. You need to create a new type 
whenever
 * you implement this interface. See {@code WorkflowRoutableType} for 
details.
 */
WorkflowRoutableType type();
}

class Workflow1 implements WorkflowRoutable {
@Override
public WorkflowRoutableType type() {
return WorkflowRoutableType.WORKFLOW_1;
}
}

class Workflow2 implements WorkflowRoutable {
@Override
public WorkflowRoutableType type() {
return WorkflowRoutableType.WORKFLOW_2;
}
}

If you create a new Workflow3 class implementing the WorkflowRoutable 
interface, the compiler will require you to override the type method. As a 
result, you'll have to create a new enum type with its version of the useful 
information method.

One side effect of this solution is the ability to discover WorkflowRoutable 
types in runtime easily:

for (WorkflowRoutableType type : WorkflowRoutableType.values()) {
type.usefulInformation();
...
}

And then you kill two birds with one stone. ;)

Cheers,

HP

With the EOEnterpriseObjectClazz you have a static instance within your class

create some empty interface (IHasClazzObject) as marker.

EOEnterpriseObjectClazz with interface

[Morris, Mark]

Hi all,

I ran into a simple case where a good old ObjC protocol would have worked fine, 
but Java provides only frustration. 

I wanted to require that a class that decides to implement a particular 
interface should as part of that interface implement a certain static method. 
No go in Java.

The implementing classes will always be subclasses of ERXGenericRecord, and a 
little searching uncovered the promising EOEnterpriseObjectsClazz approach. 
Right at the top it says:

In Java, static methods are similar to class methods in Objective-C, but one 
cannot use static methods in interfaces and static methods cannot be overridden 
by a subclass. Using the clazz pattern removes those limitations.

However, I didn’t see any examples of this use, and spent a little time but 
couldn’t figure it out. Are there any examples out there?

Tip: Touch bar with Eclipse

[Morris, Mark]

All,

Discovered this when I got my new laptop, and thought it others might find it 
useful.

I want function keys, without having to press the fn modifier key, when I’m in 
Eclipse (mainly for debugging; F5 = step into, F6 = step over, etc.). It turns 
out that’s easy to configure.

Go to System Preferences -> Keyboard -> Shortcuts -> Function Keys, click the 
plus button, then select the Eclipse app. Now when you’re in Eclipse, the 
function keys are the default, and pressing the fn key brings up the volume, 
brightness, etc., controls.

Re: EOF bug?

[Morris, Mark]

Hi Samuel,

Thanks so much for the file!

Hopefully this doesn’t come across as pedantic, but I partially disagree with 
your statement below. You should feel safe to reimplement basic functionality, 
at least with Apple’s frameworks. Just for example, perhaps you would want to 
subclass NSArray to implement a HighPerformanceArray, where maybe it switches 
to a sparse array implementation when appropriate and/or does some sort of 
Huffman encoding if the array gets above a certain size. The theory is that 
don’t need to reimplement every method in NSArray, just the base methods that 
access the fields directly. That’s what the list in the documentation is 
supposed to tell you, and it’s not supposed to be a risky proposition.

Given that, though, they clearly messed up here. ;-)

Thank you again, and take care!

Regards,
Mark

Mark,

objectsNoCopy() is declared in NSArray so all subclasses should have a working 
implementation.

It is very risky to subclass and try to reimplement the basic functionality,you 
need to make sure the subclass conform to all the superclass behaviour past, 
present and future...  Interface are there for multiple implementations 
abstraction.

I attached my version of the java source to put in ERExtension in the 
cone.webobjects.eoaccess package.

Samuel

Just a little more info I discovered.

This appears to have hit a subtle implementation problem with NSMutableArray. 
Its implementation of addObjectsFromArray() uses a protected method, 
objectsNoCopy(), on the *argument* array, not on *this* array. That seems to me 
to break the contract of “protected”. The argument array could be a different 
subclass, with a different implementation, and, based on the documentation, 
might not even implement objectsNoCopy().

So even if the writers of _EOExpressionArray had reimplemented NSMutableArray 
as required by the documentation (which they didn’t), this bug would have still 
surfaced due to the architecture issue in NSMutableArray’s implementation.

Mark,

OK, I see, _EOExpressionArray is a very bad exemple of inheritance... 
pretending to be a NSMutableArray but in fact using a NSMutableArray and 
implement some parts of it.

I do not see an easy way to patch this except by adding another fixed 
reimplemented class in ERExtensions.

I reimplemented it by removing the _array member and adjusting the Clone 
method. Just adding the objectsNoCopy() will not solve other NSMutableArray 
method mis behaviours.

Either the class is really a NSMutableArray or should not extend it and only 
the implemented methods will exists. With the current situation where we do not 
compile the WO frameworks, I think adjusting the hierarchy is not possible.

Here is my Clone method. All references to _array including methods that only 
forwarded the call are removed.

public Object clone()
{
_EOExpressionArray aCopy = new _EOExpressionArray(_prefix, _infix, _suffix);
aCopy.addObjectsFromArray(this);
return aCopy;
}

The problem seems to stem from the fact that _EOExpressionArray extends

Re: EOF bug?

[Morris, Mark]

If it’s true that Wonder hasn’t patched _EOExpressionArray, I guess the 
simplest solution would be to add an implementation of objectsNoCopy() there. 
It looks like it might be as simple as:


   protected Object[] objectsNoCopy() {

  return _array.objectsNoCopy();

   }

Hello Mark,

Your question is sound, thanks for asking it.

All display groups “batch” - in that they allow you to show perhaps 10 objects

I maintain that “ERXBatchingDisplayGroup” is poorly named and for your purposes 
you should switch to “ERXDisplayGroup”

You see… the average display group fetches all objects into memory. If this is 
5,000 records, no big deal. If this is a million records, might start to suck. 
Regardless… the average display group fetches all objects but then shows a 
handful at a time.

An “ERXBatchingDisplayGroup” is not an average display group. It is hiding a 
“top n query”

You would use this “non average” display group when you want to give the feel 
of random access to a rather large result set. You would do this because even 
though it may represent 10 million records it only fetches about 100 of them at 
any given time and then displays perhaps ten of them on the page. It is very 
good with memory but you don’t have all the objects at your fingertips.

the intention of the frameworks.

One important thing to note (and this seems to be a major stumbling block for 
all non-WOers): We are programming objectoriented, we are not programming SQL / 
database stuff!!

When you think "OO" you think "object". An object encapsulates state and shows 
behavior. When you start to learn oo-programming you usually have instance 
variables and methods. The object's state is kept in the instance vars and the 
behavior is defined by the methods. It is good and strongly recommended style 
to make instance variables private (or maybe proteced) and create public 
accessors (getter and setter methods). One should never access an object's 
state directly (instance variables) from outside the object but access them 
through the getter and setter methods. This allows the object (actually the 
programmer writing the class) to re-implement the internal representation of 
state in any way that makes sense. Any piece of code using the getter/setter 
methods won't be affected by that.

The EOF allows you to implement objects in a way so that their internal state 
is not kept in instance variables but is connected to a database record. 
Correct oo-thinking says "I access the object's state via accessor methods. I 
don't care where/how the object manages to store that state". Your enterprise 
objects are based on classes that inherit from framework classes. There is 
functionality in those classes to pull/push state to/from a relational 
database. You as the "user" of the object DO NOT CARE! The EOF framework 
manages this for you.

You MUST NOT THINK "database/table/record" but THINK "OBJECT".

Instead of asking "how do I retrieve customer records from the database?" you 
should think "how do I make the framework give me a list of customer objects 
that have their state backed by a record in the database?". With this in mind 
EOF becomes almost trivial to use. Any programmer coming from "standard java" 
background has a problem with this thinking because most persistence frameworks 
are more or less nicely built "sql generators". Thus one's thinking is often 
closer to "data record" instead of "object". Not so with Wonder and EOF. Just 
think "object" and you are all set.

With the EOModel you basically tell the EOF framework how to "map object 
thinking into a relational database". Let the framework do it, you are an 
oo-programmer!

Hope this clears things a bit.

Have fun

To expand on that a bit, which fields are editable for each permission level is

No, it’s really just something bolted on top of a permission system on a suite

WOOgnl, redux

[Morris, Mark]

This is a topic that was discussed back in 2011, but my searches haven’t turned 
up a satisfactory solution.

Some quick background info, we have information-dense, complex pages, and there 
are a variety of permission levels for internal and external users that needed 
to be implemented at field-level granularity.

My approach was to create a method for determining edit-ability in the 
superclass for each area’s components that maps permission level with field 
name:

public boolean editingEnabledByField( String field )

… which I’m calling using WOOgnl in WOConditionals as the condition and in 
custom components like this:

   

This actually works fine as far as the functionality goes. The issue is our 
logs get filled with warnings that look like error messages, one for every 
field for every page hit. Since the bindings on these pages are synchronized, 
the log messages apparently occur when the value of “editingEnabled” tries to 
get pushed into “editingEnabledByField(”thisFieldName”)”, which obviously isn’t 
possible. (So getting the value from the ognl expression works fine, setting to 
the ognl expression does not.)

In 2011 Mike Schrag wrote about almost this exact same question:

> this seems wrong to me ... it's not the ognl is intrinsically unsettable it's

The patch he was referring to was:

 public WOOgnlAssociation(String s) {
 super(s);
 _isValueSettable = false;
 }

… which is a sledgehammer approach that probably wouldn’t be applicable in 
general. However, picking up from where Stefan left off there, perhaps this is 
at least a partial solution (that I think will work for my case anyway):

public WOOgnlAssociation(String s) {
super(s);
if( s != null && s.matches( ".+\\(.*\\S.*\\)" ) ) {
_isValueSettable = false;
}
}

This regex checks to see if there’s a method call with some sort of parameter 
(by looking for something followed by “(“ followed by some non-whitespace 
followed by “)”).

Does this seem reasonable? Any counterexamples where a matching key path should 
be settable? I know that ognl expressions can include parentheses as well, but 
I would think those also would not be settable, right?

Thanks for any tips or advice!

Mark

Re: Slow requests

[Morris, Mark]

Hi Birthe,

I’m not sure if this is the best way, but it’s what first comes to mind.

You could override WOApplication’s takeValuesFromRequest or invokeAction (or 
both, using the former if available and the latter otherwise) and save the 
current time in the WOContext’s userInfo before calling super. Then in 
WOApplication’s appendToResponse, after calling super, you could log the URL, 
the elapsed time, and any other useful info you might have access to (from 
WOContext you can get to session, for instance). You could also if desired put 
a threshold on min duration to be logged, to avoid logging every request. Just 
a though.

We have something similar keeping track of long response times using 
WOSession’s awake and sleep, so that’s another avenue for session-based 
requests.

Hope this helps!

Regards,
Mark

Re: GCPieChart

[Morris, Mark]

This is probably just as ancient as GoogleCharts, but for server-side 
generation I thought JFreeChart () was pretty 
cool. The factory classes make it really easy to generate (and customize) an 
amazing variety of charts. I’ve used it directly and it's straightforward to 
integrate into WO (or pdf generation, etc.), but I think Wonder might have some 
classes built on it as well.

If you’re keen on GoogleCharts.framework, there are some examples in the

With forms that persist a password value I bind to a component ivar, check

problems because validateValueForKey gets called twice, first at component 
validation level and then when things are actually saved (I think it’s called 
by validateTakeValueForKeyPath  first and validateForSave later right?).

Result: My digest algorithm is applied twice and this obviously messes up with 
the whole thing.

What should I do to avoid this?

One idea would be to intercept component validation on 
validateTakeValueForKeyPath and skip coercion there. Or skip it later on the 
validateForSave.

What would be the right way? Also… is it somehow guaranteed that validation 
happens twice? Could it happen three times? More? If so, my idea would not work.

What do you think?

Re: Tip request: How to avoid coercing twice in NSValidation

[Morris, Mark]

I know this is off topic, but I would recommend BCrypt for your passwords. It 
has 3 features that make it better than simply hashing your passwords:


  1.  It uses a different salt for each password,
  2.  It handles version control automatically (we used to have code to handle 
when we migrated from one hash algorithm to another), and
  3.  It has a parameter to control how computationally expensive the process 
is, so as hardware gets faster you can easily keep pace.

I’ve heard that there are newer schemes out there that also have these 
advantages, so I’m sure they are good as well, but I wouldn’t stick with just 
running it through a SHA256 or similar hash.

Back on topic, I take Sharpy’s approach. ;-)

Mark

Hi Riccardo,

I’m interested in how others deal with this too.

My approach is to never bind directly to the password attribute.

With forms that persist a password value I bind to a component ivar, check 
validity on the raw string to whatever my password policy might dictate (in the 
component’s action method) then call the password attribute setter passing the 
digested string.

Sharpy..

what kind of strategy do you have when your data is in the terabyte or petabyte

We use Oracle databases, and utilize their backup solution. We also use their 
replication technology to keep two other databases up-to-date, using the 
co-located one as a read-only query database (our apps have connections to this 
for certain types of queries) and the one in a separate city as a disaster 
recovery system. With these two available to quickly switch to in the case of 
losing the primary database, the backups are used more for the type of 
emergency where we need to restore a copy of a table to some previous state.

Thanks for not letting me pretend troll you into a distro war. They all work

I wont be drawn into any flavour-distro wars (!), suffice to say Amazon

Yeah, at the risk of starting a war, my advice would be if you’re in a position 
to choose, choose PostgreSQL over MySQL.

Re: Reading in a framework-level resource in a Maven-built app

[Morris, Mark]

Hi Paul,

I’m sorry, I don’t have experience with the building with Maven aspect. It 
seems like while running with the project open in Eclipse that it can find the 
resources in the FrameworkName/Resources folder, so perhaps you could try using 
2 copies in your framework project, one in each place? It seems like the best 
solution is if Maven knew to get the resources out of the spot where they 
traditionally live. (As I recall, back in ProjectBuilder they were in 
FrameworkName/Resources as well.)

Good luck!
Mark

Sorry, it was a little bit unclear.

but WOResourceManager will find files in frameworks just fine if they’re in the 
Resources folder. Note that this is not under any XXX.woa/Contents/Resources 
path as mentioned in your email, you just put the files in the 
FrameworkName/Resources folder

I’m building with Maven, so I’ve put the resource in 
FrameworkName/src/main/resources...

and they end up under FrameworkName.framework/Resources within the jar.

Yep, confirmed.

You do have to supply the framework name in the call to WOResourceManager, such 
as:

InputStream is = 
WOApplication.application().resourceManager().inputStreamForResourceNamed( 
“foo.txt", “FrameworkName", aLanguagesList );

This where I might have rushed the question a bit. What I am after is code that 
works both when the framework is open in Eclipse, and when it’s not and it’s 
instead referencing the built JAR under ~/.m2/repository (or wherever). So if I 
close FrameworkName.framework in Eclipse, your code above does work. If I open 
it again, the InputStream returned is null. But what _does_ then work is:

URL url = getClass().getClassLoader().getResource(“foo.txt")

To be completely clear this time:

1. If framework project is closed in Eclipse (and application is hence using 
framework under ~/.m2/repository), 
WOResourceManager.inputStreamForResourceNamed() works fine.

2. If framework project is open, 
WOResourceManager.inputStreamForResourceNamed() returns null, but 
getClass().getClassLoader().getResource(“foo.txt") does return a URL that can 
be used.

So, to load a resource from a framework, I’ve got to try both methods. Is this 
expected behaviour for a Maven build, or am I doing something wrong?

Re: Storing Session ID in Cookie And Multiple Browser Windows

[Morris, Mark]

Hi Michael,

First upon successful login we set a random secure cookie value, but the trick 
is I also make sure the cookie *key* is unique by using a suffix on the key I 
can increment if necessary. Both key and value are stored in the session, so we 
can compare later, and the cookie needs a reasonable timeout (unrelated to 
session timeout) so that old keys disappear from the user's browser least 
within a day or two. This setup keeps cookies from different sessions from 
stepping on each other, which is important for our customers, who regularly 
have multiple tasks going on in separate windows.

Then in our subclass of ERXComponent I override checkAccess() to check that the 
in-memory key and value matches what’s in the request’s cookies.

You have to override checkAccess() further down the chain for specific pages 
that shouldn’t ever deny access, like the home or login page, or your main 
checkAccess() can consult some list of "always allowed" pages, or some similar 
mechanism. Also, as I recall there was some timing issue with the very first 
request if you’re setting the cookie after login and immediately going to some 
protected page. For that I think I set a one-time flag on the session that 
basically says, “this is the request-response loop in which the user has 
successfully logged in”, so checkAccess() can ignore the missing cookie. Of 
course somewhere at the end of that loop, the flag needs to be reset.

I think that’s the main part of what we do that relates to your question. Hope 
this helps!

Take care,
Mark

Re: Storing Session ID in Cookie And Multiple Browser Windows

Hi,

We use a combination of the session ID in the URL plus a secure cookie that we

this is a viable option in your case, but it does allow multiple sessions.

customization options, and a variety of output formats. So for instance you can 
just include a method that returns the image data and use that right in your 
WOImage binding.

Good luck!

Re: Remove blank space at the end of all insert/update

[Morris, Mark]

Hi Luiz,

One step closer might be to use a StringHelper class, so that you can define 
directly in your .wo the fields on which you want whitespace trimmed.

See 
 
for more info.

Hope this helps!

Re: Horizontal inheritance to splitting big database tables to speed up?

[Morris, Mark]

Hi OC,

I don’t know that there’s a way to do this.

What I did before was to intercept at the SQL-generation stage and change the 
table names based on a session variable value. This was not for performance in 
my case, it was because a horrible student information system at a school 
system I was at duplicated every table for every school in the system, with a 
school-specific suffix added to the table name, and I was hiding that 
complexity from the rest of the app development. I could see how something like 
this might be used in an extreme case to address performance issues, but it 
certainly depends on your situation.

Re: Splitting big database tables to speed up?

[Morris, Mark]

I saw something, when I just did a quick search, called “zones” that have a 
“data” option, that on the surface sounds somewhat similar, but I’m not sure if 
they will have the same performance benefit that Oracle partitions produce.

Yes, we have tables that huge, and larger, so it makes a big difference to us. 
If you’re in this really huge situation as well, there are even more drastic 
measures possible. You could create separate physical databases, on multiple 
servers, and direct users upon login to instances that are pointing to the 
appropriate database. This would give significant performance gains, at the 
expense of significant increase in complexity.

Good luck!

Re: Splitting big database tables to speed up?

[Morris, Mark]

Hi OC,

I see now. Besides the table-renaming-at-SQL-generation idea someone suggested 
(which certainly works, I’ve used in the past to hide the complexities of an 
old system migrated from many distributed AS400s), there might be support in 
your database for something that will get you the same results. We also have 
quite a few really huge tables, in Oracle, and we use table partitioning. You 
can partition on a value, and then all of the records in a partition are kept 
physically together and treated by the optimizer for all practical purposes 
like separate tables. Indexes can also be by partition, so the index search is 
limited as if it were a separate table as well. Huge performance gains for us.

Good luck!

Re: Splitting big database tables to speed up?

[Morris, Mark]

Good point. If new T_TABLE records are added infrequently and don’t need to be 
visible immediately, any mucking with the model could safely be done on app 
startup, and so changes would be available after the next regular instance 
restart. Otherwise it’d be wise to pay heed to Chuck’s warnings.

Just a thought. What about dynamically creating a new EOEntity for each group 
of T_RECORD records represented by a T_TABLE record? Then you could add a 
qualifier to the EOEntity that would restrict it to the correct subset, and it 
would be included automatically in the SQL. You could use inheritance maybe, or 
just copy the attributes/relationships from your base entity. Inheritance would 
let you use your custom java-based logic that’s in the base entity, though.

Re: Splitting big database tables to speed up?

[Morris, Mark]

Just a thought. What about dynamically creating a new EOEntity for each group 
of T_RECORD records represented by a T_TABLE record? Then you could add a 
qualifier to the EOEntity that would restrict it to the correct subset, and it 
would be included automatically in the SQL. You could use inheritance maybe, or 
just copy the attributes/relationships from your base entity. Inheritance would 
let you use your custom java-based logic that’s in the base entity, though.

Mark

Re: Use case for a "case insensitive equals" qualifier

[Morris, Mark]

Hi Samuel,

That’s certainly a possibility we’ve talked about, and for sure it would 
improve the performance vs. my solution. The tradeoffs to consider are that we 
have many columns across many tables where this is used, with 100’s of millions 
of records, and so each new index is a huge chunk of storage space. I think in 
the end, though, we should probably do as you suggest, at least for a selected 
subset of those columns.

As a general case of just optimizing the qualifier though, having the 4 index 
lookups, with the merge, is in practice much faster than one full table scan, 
so it seems like a useful tool to have.

Regards,
Mark

Hi Mark,

I suggest you look into adding a collation to your column or index. I do not 
know how Oracle does this but it surely exists.

With an index using a collation, your query is trivial and much more efficient 
because the index is already case insensitive, there is no OR.

A query like the one you build generate multiple index lookup, one for each 
part of the OR and the server need to merge all those results before iterating 
into the rows, compute the UPPER for each rows and compare. Imagine the speedup 
if a single index lookup can be used, I would expect at least 10X faster on 
large dataset... probably 100X if multiple OR parts returns 1000s rows.

Hmm, it would be interesting if there was an alternative, but really the 
problem lies in the database.  Any wildcard type searches (at least that start 
with a wildcard) are not likely to use indexes and cause a table scan.  If your 
database supported the concept of having case-insensitive indexes, then I would 
think it would be pretty trivial to implement in your own qualifier.  In Sybase

If there’s interest, perhaps I could try to see about adding it as an ERX

Re: On SQL fully qualified names and how to implement them in EO models

[Morris, Mark]

Hi Angelo,

I don’t really have anything constructive to add to what others have already 
said. I’ve always had a app user database login, separate from the table 
owner(s). (This allows you to restrict what the app can do, such as only insert 
into audit tables.) Then, in Oracle anyway, you can create a synonym in the app 
user schema to point to the table, no matter which schema it’s in. Another 
option, if they’re all in a single table owner schema, is you can set a 
default schema name for the app user.

You have the flexibility to get as custom as you need to. For example, I had 
another application once where the table names actually had to be changed 
dynamically (not my design!). The schema for most of the tables was repeated 
over a hundred times, once for each customer, with a different suffix. Instead 
of modeling it over and over I intervened in the SQL generation to substitute 
the currently active customer suffix. The result hid all of the complexity 
nicely.

Anyway, good luck with your project. :-)

Mark

Re: Relationships: when NOT no to flatten

[Morris, Mark]

Correct! :-)

Flattening would only be useful if you wanted to logically have the 
relationship:

Quote --- Product

Since there is actual information in the QuotedProduct join table, you don’t 
want to flatten.

Regards,
Mark

 Hello, people!
 
 
 I am experimenting a little more... and hitting some roadblocks!
 
 Example: I have these entities called Product and Quote. A Quote has many 
 products. But each quoted product has more information, like price, quantity 
 and lead time. So, I am using this QuotedProduct entity, which binds the 
 Product id, the Quote id and the other information.
 
 The relationship could be expressed like this:
 
 Quote --- QuotedProduct --- Product
 
 I understand I shouldn't flatten any of these relationships. Am I right?
 
 
 Cheers,
 Flavio

Re: Globally inspecting and conditionally altering fetch spec

[Morris, Mark]

Hi Maik,

We're using partitioning on most of our larger tables. Usually the root entity 
on any fetch spec will have a qualifier that will enable the database to make 
use of partition pruning. However, any of the various joined tables in 
generated SQL that should also be able to use partition pruning won't have the 
qualifier, and so performance suffers significantly.

We've gotten by with solutions for specific queries, but I'm hoping to solve 
the general case for any generated SQL. So my thought is, check the root entity 
for the partitioning attribute. If it's there, check the qualifier and grab the 
value if it's included. If so, loop through the joined tables, checking for the 
attribute, and add the qualifier to the fetch spec for each one that has it.

This is obviously very implementation specific, so that's another reason it 
would be nice if all the code involved was centralized in one spot.

Thanks for taking a look!

Regards,
Mark

Re: Globally inspecting and conditionally altering fetch spec

[Morris, Mark]

Right, that's what gave me some pause. It looks like, if I want to use a 
different fetch spec, I need to do the fetch myself in the delegate method and 
return the results. It would be nice if there was someplace where inspecting 
and changing the fetch spec was an okay thing to do.

Thanks again!

Re: Globally inspecting and conditionally altering fetch spec

I was looking for something like a delegate, but maybe just subclassing ERXEC 
and overriding objectsWithFetchSpecification would be a more straightforward 
way to go….

editingContextShouldFetchObjects, but I was curious if anyone might know of any 
gotchas there or if there might be a better approach.

The why is optimization. By altering the qualifier, I can greatly improve 
performance of these queries (say 20x).

The what is just that, I need to watch for a certain class of queries, and if I 
see one, alter its qualifier, then let it continue processing.

Thanks again!

Thanks for the response! :-) Aren't those classes usually used explicitly? I'm 
hoping to watch every single fetch that's generated and pick and choose the 
ones I want to alter.

You may want to take a peak at ERXFetchSpecificationBatchIterator or

Hi all,

If I want to check for a certain class of query, then alter the qualifier 
before the fetch is executed, any suggestions for the best approach? So far 
what I've come up with is registering for EOEditingContext.Delegate's 
editingContextShouldFetchObjects, then performing the fetch from there if the 
fetch spec matches my conditions.

Thanks for any advice!

Regards,
Mark
