RE: Excel and Coldfusion and Javascript
If you're going to the Excel manipulation server-side then this is probably a good bet: http://jexcelapi.sourceforge.net/ You will need to install the relevant jars on to your server, update your java classpath in cfadminstrator and then call with cfobject. After that it should be a simple case of accessing the methods as per the jexcelapi docs. I have a good look at this for copying some data into an Excel template (preconfigured with macros, cell protection etc and some formulas for assisting data manipulation) and it seems just the job, but I haven't done any actual coding yet.

Re: CFmenu submenu icons
Brian, Use firebug to inspect the element which should let you know what the style class for that element is. Then all you have to do is override the element in your page or include your own style sheet. The class is located in the inetpub\wwwroot\CFIDE\scripts\ajax\resources\yui\yui.css. The class is called submenuindicator and uses an image called map.gif to provide the icon.

Re: Combining Verity searches and SQL Searches
You could do this two (at minimum) ways. One is to add the db content to your Verity collection. Then you can just search the Verity collection. Another option would be to perform both searches and join them using QofQ. The main problem you would have (I think) is sorting, as Verity returns a score. Although I believe if you use full text searching in SQL Server (or MySQL) you can get a score value as well. How well it meshes w/ Verity's score is another matter.

You can extend the parent Application.cfc in the child Application.cfc.

Copying a CFC Persisted in Session Scope
Greetings all- I realize this topic may have been covered on this list a while back, but I'm having problems locating a good answer, so here goes. Typically in our administrative web sites, on a request, we copy over our session variables to the request scope so we can have read-access to the information without having to place locks all over the place. Now that we're doing more OO stuff, I would like the ability to persist an object in the session scope while a user is signed in, and then copy it over to request for the same purpose. As you know, cfset session.object = request.object / only creates a pointer to original, and duplicate() doesn't work on CFCs (we're using CFMX 7).

As you know, cfset session.object = request.object / only creates a pointer to original, and duplicate() doesn't work on CFCs (we're using CFMX 7). Anyone have a workaround or best-practice solution for this type of thing? No workaround is needed. You don't need anything more than a reference to the object. When request.object (which is itself just a reference) goes out of scope, session.object will be the only remaining reference to that object. Now, if your goal is to prevent changes in request.object from affecting session.object, that's something else entirely. In that case, though, I don't see why you'd need both references.

RE: Configuring CF Datasources
Can CF use datasources that have been manually created using the Windows ODBC Admin program? Or does CF require all datasources be created through the CF Admin screen? For ODBC datasources, you will need to first define them as System DSNs within the ODBC Administrator, then define them as CF datasources within the CF Administrator. Of course, you should avoid using ODBC if possible, as it generally won't perform as well as pure Java type 4 JDBC datasources. You should only use ODBC for databases that don't have corresponding JDBC drivers.

RE: Copying a CFC Persisted in Session Scope
I realize this topic may have been covered on this list a while back, but
I'm having problems locating a good answer, so here goes. Typically in our
administrative web sites, on a request, we copy over our session variables
to the request scope so we can have read-access to the information without
having to place locks all over the place.
I would suggest that you create a Session Facade and then have all your
objects reference the façade. It is generally a bad idea to have an object
reference an external scope (session, request, etc.), and this technique
hides the implementation from your business objects.
Assuming you wanted to return an 'admin' object, your objects would use a
sessionFaçade.getAdminObject() and the function within the façade would look
like the following (excluding locks, etc. for the sake of simplicity):
function getAdminObject() {
Return session.adminObject
}

Re: Copying a CFC Persisted in Session Scope
Anyone have a workaround or best-practice solution for this type of thing? The easiest would be that one no longer needs to have locks everywhere when reading session or other global scopes. The bugs that where the reason for this old rule of thumb have long been handled. This has not been a recommended practice since before MX6.1 IIRC.

I don't see the problem, users with Web accelerator get their stuff from Google's cache, not from my server, so I don't even hear about them.

If something hits the main Application.cfc, the Canvas onApplicationStart() etc. won't be run. Conversely, what if someone hits the Canvas app BEFORE the main application has been run? You may want that to bubble up to the main app so that it's onApplicationStart() runs, which means doing a super.onApplicationStart() if the main application isn't already set up. You could add a condition to this so it only happens if the main app isn't set up yet. If not, just don't call the superclass methods. I'm not sure what you mean by conflicting application values, but these will probably need to be handled on a case by case basis. The bottom line is that to share the session scope between the two apps, they have to share the application name. It might be a good excuse to refactor things so that the application variables in the main app are segmented from the application variables in the child app(s). It's also a good demonstration of why one might not want to place lots of data directly into the base application scope but instead into structures within the application scope. ~| Get involved in the latest ColdFusion discussions, product development sharing, and articles on the Adobe Labs wiki. http://labs/adobe.com/wiki/index.php/ColdFusion_8 Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:292249 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4

Re: Copying a CFC Persisted in Session Scope
I'm not clear on why you would want to copy the instance instead of create a reference to it. That said, you could serialize the original and then deserialize the serialized version to make a true clone of the object (this requires using Java though). You could even wrap up this logic into a cloneComponent() method and attach it to the component that you want to copy, if you really wanted to. The benefit (or drawback) here is that the clone would also maintain copies of any composed components that the original had. So not only would you lose any references that other objects had to the original instance, you'd also lose any references that the original instance had to other objects. In any event, unless you have some fundamental reason to want a copy, just use a reference.

No, Google Web Accelerator doesn't rely on Google's cache, it prefetches links from your server. Are you sure about that ? It uses client software installed on the user's computer, as well as data caching on Google's servers...

Storing copies of frequently looked at pages to make them quickly accessible. ( http://webaccelerator.google.com/support.html ) The acceleration is acheived by both compacting the page content and using the super fast Google network to get the content.

Re: CF8 AJAX form question
Jeff, I think we might need more clarification here. ...update form elements as a user makes changes has a few different meanings. If field elements (say city and state) are bound to other elements (like a zip field), then you might use Ajax to update the city and state with info brought back from a query to the server (this zip = this city and state), whereas if you were just applying proper formatting to a field's contents (say a U.S. Phone Number field), you aren't really using Ajax, since you aren't making a query of the server for information based upon what you've entered.

Re: CF8 AJAX form question
Ok... Hopefully I can explain this a little better.
In simple terms... Say I have a mailing list signup form with different news
letters.
=
{{You have been added to [mailing list X] using [email address select]}}
[ ] Mailing List A [email address select]
[ ] Mailing List B [email address select]
[ ] Mailing List C [email address select]
==
Legend:
[ ] Check Box
[email address] Select box
{{Ajax updated div inner html}}
The wanted action:
As a user clicks the checkbox to a particular mailing list, I call a CFC and
add that person to that particular mailing list via an insert query and
update the HTML above to let the user know they have been subscribed. OR if
the checkbox is already checked, and they click on it, unsubscribe them in
the same manor.
Did I make this clearer or did I make it more complex???

RE: Copying a CFC Persisted in Session Scope
The objects I am copying from are persisted in the session scope. I would
like to be able to read from these objects at runtime without having to lock
them all over the place. Does creating a pointer in the request scope to an
object in session absolve you from locking? I'm not sure, and to be honest,
I haven't found a lot of information either way on the issue, so copying the
object seems to be playing it safe, no?

Re: Query of Queries causing server to hang
Graham, I haven't seen this exact error before, but do you perchance have a cflock around the QoQ code? Query of queries are very expensive on the server and grow more so as the record set being manipulated increases. Many times, the same functions performed in QoQ can be performed by rewriting the SQL used in the original query to return a more efficient query from the start. If you must use QoQ with a large record set, you might try adding caching to the query to lower the overhead or scoping the manipulated record set as appropriate for later re-use. The lock may be increasing the problem as the thread count stacks up while waiting for the ability to lock. Once that happens, and CF reaches the maximum number of requests (as configured in the CF Admin) the initial request may not finish and the memory used to manipulate and handle the query record set may not be cleared for other requests. I had to do some SQL optimizing last year on a client site which was having similar issues.

Re: CF8 AJAX form question
This can get tricky because the user can fill out the form without using the
mouse by tabbing with the keyboard. So you'd need onKeyPress handlers for
each field as well.
I suppose I'd be careful with this, but nothing is stopping you from doing
it. Most people are used to having things save when they click the submit
button, so consider that this autosave approach might confuse some people.

Jeff,
I think we might need more clarification here. ...update form elements
as a user makes changes has a few different meanings. If field
elements (say city and state) are bound to other elements (like a zip
field), then you might use Ajax to update the city and state with info
brought back from a query to the server (this zip = this city and
state), whereas if you were just applying proper formatting to a field's
contents (say a U.S. Phone Number field), you aren't really using Ajax,
since you aren't making a query of the server for information based upon
what you've entered.
I would suggest reviewing some of the popular JS libraries for either (I
prefer JQuery myself). If you are on CF8 you can take advantage of the
new built in Ajax components and methods (see the livedocs for detailed
implementation).

Server performance problem since upgrading to CF8
Every since upgrading to CF8 I've been having a frustrating problem. After starting CF, it will run for a while (sometimes serveral hours, sometimes less than an hour) at about 1% - 3% in terms of processor load. (It's a 2 cpu - 4 core system.) Then, all of a sudden, the processor load will jump up to about 25% and stay there until CF is restarted. Pages then start loading very sluggishly. This never happened with CF7 and I haven't made any code changes since upgrading. Also, the CF code that this server runs is very light. Anyone seen this, or have any ideas.

There should, since MX6 or so, be no reason to create read-only locks unless you have some sort of weird race condition going on.

So, you don't need to be absolved from locking even if you are referencing the session scope directly -- CF is forgiving. :-) --Ben Doom Ryan Heldt wrote: The objects I am copying from are persisted in the session scope.

As I pointed out previously one NO LONGER NEED to lock reads and other non-race condition writes to session, application and server scopes. This problem was resolved several version ago. One could quite happily and safely access the session persisted objects directly if that is the only requirement for all this extra work and memory use. You will be doubling the memory requirement of each and every object you duplicate from the session scope to the request or similar scope.

RE: Copying a CFC Persisted in Session Scope
And having references to sessionFacade.getFoo() everywhere is somehow better than having references to session.foo? I think you are getting stuck on the name 'sessionFacade'; I was attempting to suggest abstracting access to the variable of which his components had no direct knowledge. If my code is calling userService.getFoo() instead of a reference to session.foo then I think that is absolutely a better choice to utilize a facade. The added benefit of using the façade is that you can unit test the service (by using a mock object). That sort of session facade is not a coherent object and having sessionfacade everywhere means you have not encapsulated use of session scope at all - you've just required that people call functions to get at data. It seems as though you are mixing concepts; a well designed object, and how it access an external scope. I believe that within a well designed object, it should not reference a scope it does not directly have access to and should use a façade to get access to that data. The better solution is to consider what data you have in session scope in the first place and encapsulate each piece of data in an object that relates to that data. I agree completely. You might have a user object in session scope - encapsulate that knowledge in a userService (singleton). That way you've encapsulated how the user is stored - none of your application code knows about session scope (or sessionFacade!). I agree that the application should utilize a service to interact (in your example) a user, but again, I think the service should not access the session directly either, it should use a façade to access the session. You ask the service to perform operations on the current user and it knows how to do that. It can even give you the user object if you want to operate on it directly. That means your application code is only dependent on a fully encapsulated service. It also means that you can change how the user object is stored independent of any other data in session scope (because that other data is encapsulated elsewhere) and nothing in your application needs to change. I could not agree more. - Rich Kroll ~| Check out the new features and enhancements in the latest product release - download the What's New PDF now http://download.macromedia.com/pub/labs/coldfusion/cf8_beta_whatsnew_052907.pdf Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:292285 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
Re: Copying a CFC Persisted in Session Scope
At the risk of disagreeing with Sean, which usually ends up with me realizing I'm wrong about something... On 10/29/07, Sean Corfield [EMAIL PROTECTED] wrote: And having references to sessionFacade.getFoo() everywhere is somehow better than having references to session.foo? I do see a difference, in that the calling code doesn't actually know about the session scope or how the data is being persisted. So I suppose a better name might be PersistenceFacade (or even PersistenceAdapter), but the point is that you are free to change how things are actually stored without changing anything outside the facade. Having a giant kitchen sink session facade CFC is not a good idea and is not encapsulation. That sort of session facade is not a coherent object and having sessionfacade everywhere means you have not encapsulated use of session scope at all - you've just required that people call functions to get at data. Isn't that the very definition of encapsulation? I don't see it as a kitchen sink, nor a non-coherent object. On the contrary, I see it as a very coherent object: it is the gatekeeper to the shared scope, and everything that wants to deal with the shared scope needs to talk to the facade. The better solution is to consider what data you have in session scope in the first place and encapsulate each piece of data in an object that relates to that data. You might have a user object in session scope - encapsulate that knowledge in a userService (singleton). That way you've encapsulated how the user is stored - none of your application code knows about session scope (or sessionFacade!). You ask the service to perform operations on the current user and it knows how to do that. It can even give you the user object if you want to operate on it directly. That means your application code is only dependent on a fully encapsulated service. It also means that you can change how the user object is stored independent of any other data in session scope (because that other data is encapsulated elsewhere) and nothing in your application needs to change. I totally agree here. I would pass the SessionFacade into the UserService, and nothing outside the UserService has any idea where it is getting or storing anything. If I call userService.getCurrentUser(), internally the service might be grabbing the object from the SessionFacade, but nothing outside of it knows that. I still think there is value in having a single point of interaction with the shared scope via the SessionFacade. If I understand your point of view on this, either your UserService would need to interact directly with the session scope, or you have to create service-specific objects that encapsulate interaction with the session scope and pass those into each service that needs them. Which means instead of having one object that deals with the session scope, now you have a bunch of them. The upside to that design decision seems to be that you have granular control over how/where the data is persisted for each service, but the downside is that you have multiple additional objects to deal with (one for each service). And since I have never run into a situation where different services needed to use different persistence mechanisms (everything is usually just in the session scope), this seems like an increase in complexity for not much real benefit. Further, since I'm passing the SessionFacade into the service at configuration time, if the need ever arises, I can simply pass in some other object that works differently without having to change anything in the service. Or perhaps are you advocating pushing the interaction with the session scope into a DAO, do be grouped with anything else that needs to be persisted (including the database)? Maybe part of the issue is that aside from a User object and maybe a Shopping Cart or something, I really don't keep much in the session scope at all. Sorry, but this weird obsession with sessionFacade CFCs drives me nuts - it's completely misguided and a very procedural way of thinking. If one had direct references to the SessionFacade all over their code, I'd agree with you. But I'd say the approach outlined above is definitely not a procedural approach. If anything, the only point of contention is your approach of having each service deal with the session scope through a service-specific object vs. my approach of having the services go through a single component to deal with the session scope.

RE: Copying a CFC Persisted in Session Scope
The objects I am copying from are persisted in the session scope. I would like to be able to read from these objects at runtime without having to lock them all over the place. Does creating a pointer in the request scope to an object in session absolve you from locking? I'm not sure, and to be honest, I haven't found a lot of information either way on the issue, so copying the object seems to be playing it safe, no? No, creating a reference in the request scope to an object in the session scope doesn't absolve you of responsibility for race conditions. But is there really a possibility for a race condition here anyway? I sincerely doubt it (although I would need to see source code to guarantee that). What I can guarantee, though, is that playing it safe in this case may not actually be a safe solution at all; locking imposes significant overhead, so using it where it isn't necessary may prevent your application from scaling as needed. As someone who spends a fair amount of my time reviewing others' code, I've actually run across this many times; far more than I've encountered race conditions.

RE: Copying a CFC Persisted in Session Scope
That is, in fact, what I am doing. I have a AuthenticatedUser CFC that contains all of the information about the user that is signed in. Now, for example, say I want to run a query that gets all of the timebills for that user, I would SELECT foo FROM bar WHERE UserID = #session.myAuthenticatedUser.getUserID()# I would prefer doing that without having to put a session lock around or in my query, which is why I wanted to copy the object down into request. Make sense, or am I going about this the wrong way? You are going about this the wrong way. There is no need to copy your session object to the request scope. There is no potential for a race condition to occur if two request invoke that method concurrently - they will (presumably) get the same result.

RE: CF / SQL Encryption
I have just received a new project that requires very sensitive information about assault victims to be stored in a sql 2k database. I have already gotten the SSL up and running but can anyone give me some ideas has to how you might securely store/encrypt that information in the database, such as full names, ssn's, addresses, etc. This is a very complicated question, and any answers you get here are bound to be less than complete. Basically, though, the answers will depend on your threat profile. Specifically, what are the specific security problems that you're worried about? If you're worried about people from the outside getting access to this data, you will be concerned about encryption from within your application server, and key management within your application server. You can encrypt values from within CF and store them within the database, but your application server would presumably require the ability to decrypt those values later, so you'd need to store the key(s) used to encrypt and decrypt values within your application server code. Someone who compromises your server may be able to acquire those keys and decrypt values. One potential solution to this would be to have separate environments for encrypting and decrypting values - for example, you might accept values from a public server, which could have an encryption key, but you might limit viewing those encrypted records to a completely separate server, which would possess the decryption key. That would obviously require separate keys for both (http://en.wikipedia.org/wiki/Public_key) If you're worried about people within your organization getting access to this data, you will be concerned about limiting and segmenting administrative access to application server code and databases. You may also be concerned about encrypting network traffic between your application and database servers. Of course, everybody's concerned with the former at the expense of the latter, even though most security incidents involve your own employees rather than some big bad hacker. I am using CF 6.1 You won't want to rely on CF 6.1's built-in encryption functionality, then. CF7 or higher include industry-standard encryption functionality.

I was attempting to suggest abstracting access to the variable of which his components had no direct knowledge. If my code is calling userService.getFoo() instead of a reference to session.foo then I think that is absolutely a better choice to utilize a facade. The added benefit of using the façade is that you can unit test the service (by using a mock object). Totally agree. Using userService.getUser() as a facade for a user object stored in session scope is exactly what I'm advocating. It seems as though you are mixing concepts; I'm not - but a lot of other people are! I agree completely. I agree that the application should utilize a service to interact (in your example) a user, I could not agree more. See, we're on the same page. but again, I think the service should not access the session directly either, it should use a façade to access the session. I think that's a pointless abstraction - see my response to Brian for why but I'll also elaborate here since this is an important point and a lot of people seem to be missing it. Only the service should know or care where the object for which it acts as a facade is stored. Introducing an arbitrary abstraction and then coupling most (all) of your services to that abstraction overcomplicates things and makes your code more brittle. Once a service has access to a generic facade like that, it can access *any* data behind that facade and the faux-encapsulation of the facade encourages developers to do so, believing they're using good OO practice. All that happens is you get increased dependencies because you've opened up a conduit to data that a service should not be able to touch. If a service needs access to data in another service, it should go through the *service* but with this generic facade approach, it can go directly through the generic facade, completely breaking the layering and encapsulation in the application. A session facade object - by any name - *breaks* encapsulation by allowing unrestricted access to *any* data for which it acts as a facade. -- Sean A Corfield -- (904) 302-SEAN An Architect's View -- http://corfield.org/ If you're not annoying somebody, you're not really alive. -- Margaret Atwood ~| Download the latest ColdFusion 8 utilities including Report Builder, plug-ins for Eclipse and Dreamweaver updates. http;//www.adobe.com/cfusion/entitlement/index.cfm?e=labs%5adobecf8%5Fbeta Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:292305 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4

By eliminating the centralized facade, you're not even giving other services the possibility of digging into shared scope data that is outside their area of concern. Right, and that's the rub... I do a lot of code audits these days and I see this cropping up over and over again: too many developers can't resist the convenience of accessing other service's data via the shared scope facade instead of going about it the right way. So I push hard to eliminate the temptation in order to break them of their bad habits :) OK, I'm sold. ;-) Cool! Still, if you could comment on your approach to dealing with the session scope in your services I'd be interested. Do you use a direct reference to the session scope? Or some other approach? In general, I isolate it into one private method that has a direct reference to session scope. The exact mechanism depends on what the cached object is and how it is initialized. For mock testing, just extend that service CFC and override that one method. That one method is often responsible for creating the cached object on-demand so the extended mock can double up as both a mock for the cache access and a way to substitute the creation of the cached object.

Re: Copying a CFC Persisted in Session Scope
I'm curious, then, how you handle reference to the session scope in your service. Do you actually reference the session scope directly? One of the things I like about the centralized SessionFacade is that it is easy to test by feeding in a fake struct that the facade uses in place of a real session scope.

The extra layer of abstraction does make it easier to test, as well as know where I need to go look for any code that has anything to do with a shared scope. If the name is really bothering you I can refer to it as SharedScopeFacade or something similar. I just call it SessionFacade because, as a label, everyone pretty much understands the concept of a session as data that exists across multiple user requests. In other words, I see a difference between SessionFacade (the concept) and, say SessionScopeFacade (explicitly stating what scope is being encapsulated). There is a trade off here (of course) and I'll argue that having a single method inside a service that encapsulates use of session scope is better encapsulation than having the service depend on an external class that lots of other components also depend on. I agree that there is a trade off, and I hope that given this and the previous post that, while you wouldn't take the same approach, that the approach I'm using is: superior to direct references to the session scope across your code; superior to the generic all-in-one session facade that uses one get and one set method; and superior to the usage of a centralized SessionFacade that is also referenced all over the code instead of only within services (and even then to a very limited degree). In other words, the disagreement between our two approaches has actually been narrowed down to a single specific issue (the single facade vs. separate interaction with a shared scope within each service). ~| Create robust enterprise, web RIAs.
