  • Connecting multiple ColdFusion 10 instances to a single Apache 2.2 server

    - by Adam Cameron
    This is on Windows 7 Home Premium edition. I have got two ColdFusion 10 (updater 2) instances: "cfusion" (the default one), and "scratch". I have got a single instance of Apache 2.2 running. Within Apache, I have set up two virtual hosts, each of which needs to be served by a different ColdFusion instance. Each of the CF instances serves files fine via Tomcat's internal web server. Apache serves vanilla HTML files fine too. So both CF instances, and both virtual hosts separately work OK. I can get wsconfig.exe to connect either one of the CF instances to the Apache server, and serve CF files via Apache & that instance. However I cannot find a way of connecting the second CF instance to Apache as well, so that both CF instances are conected, each serving one of the virtual hosts. WSConfig doesn't seem to understand the notion of "multiple CF instances", and the changes it makes to the httpd.conf (via mod_jk.conf) does not seem to be implemented in such a way as to accommodate multiple CF instances talking to a single Apache instance, or multiple virtual hosts. I freely admit to not being confident enough with how mod_jk (or even really httpd.conf) works to be able to guess if I can change stuff to make it work. If I try to add the second CF instance using WSConfig, I just get a message "the web server is already configured for ColdFusion". Be that as it may... not the instance of ColdFusion I want to connect it to! If I remove the existing connector to whichever instance is already connected, I can then connect the other one no problems. Not that this helps, but it demonstrates that the CF instance can connect to Apache. This all used to be fairly straight fwd under older versions of CF and JRun :-( The only docs I have found are on the "Connect multiple Apache virtual hosts on a web server to a single ColdFusion server" page, but that specifically only deals with a single CF instance. There is no equivalent page for multiple CF instances. I'm kinda hoping I can move some of the mod_jk config into my virtual host entries in httpd-vhosts.conf (this is how it used to work for JRun), but I've no idea what to put where. I think I've covered all the necessary info here? If not, sing out and I'll add more. Thanks. PS: tried to specifically tag this as "ColdFusion-10" as the answer will be different from previous CF versions, but it won't let me cos my rep on this site is too low (odd how it doesn't consider my rep from other S/O sites...). If someone with sufficient rep can add it, that'd be cool: it's probably a valid tag to have. Ta.

  • Coldfusion server VERY slow page loads

    - by Kevin
    I inherited a windows server 2003 coldfusion 7 server a few weeks ago. Today a network cable was unplugged by accident from the server. On plugging it back in, pages were NOT loading at all. Rather, we were receiving a generic coldfusion error page. After restarting IIS several times and coldfusion even more than that, we finally got pages to start loading. However, the loading is extremely slow (30+ seconds) on pages that used to load instantly. Loading through the local network (IE localhost/cfide/administrator) does nothing to help the load speed. I am not familiar with IIS or Coldfusion (We're in the process of migrating this to Linux/PHP), so this is all new territory to me. I'm hoping someone may have experienced this issue in the past and can help me solve it. I'm happy to provide any additional information that might be necessary....I'm just not sure what information you might need in order to help. Thanks for your time.

  • Check for live Data Source Name Before proceeding

    - by n_kips
    Would it be ok to get a CF app to check for a valid database before proceeding to process that request? This is because there may be instances where the database server may be down or being upgraded, hence an error comes when a db dependant request is made. If there is no connection to the db server, the user can be safely redirected to a safe page. Or can cfcatch work? How can this check be done? Thank you.

  • Will learning ColdFusion help me advance my programming skills? [closed]

    - by chhantyal
    Currently I am working with a small web development company. We use jQuery on front-end, Coldfusion for back-end and MySQL as our database. We just started to use HTML5 and CSS3. This is my first internship and job. I know the basics of Python and want to add Django or Ruby on Rails on my skills set. In addition, I want to advance my programming skills with Machine Learning, Compilers, NoSQL and Unix Hacking. I also find front end web development pretty interesting. Should I focus on front-end and become skilled on HTML5/CSS3/Javascript? Or dive into back-end learning ColdFusion. I will probably leave the company after a year since I want to work with great product start-ups. And I live in India, where ColdFusion is not popular. Will learning ColdFusion help me become better programmer?

  • How can I setup ANT with Subversion and ColdFusion Builder (eclipse) to check out a local build to w

    - by Smooth Operator
    I am not sure if there's an answer for this already -- couldn't find one for this (hopefully common) setup: I recently converted one of my ColdFusion projects to deploy via ANT. I have a local ant script that instructs a remote server to check out the code, and run the application's specific build file, remotely on the server. I have a few endpoints: Live - production (on the production server) Staging - on the production server, different datasource, etc. dev - on the local box. What I have run into it seems is a simple and common problem. I now need ANT to create any build, even locally. Fine, created a local endpoint and it configures for my box. Issue? How do I get it to show up as a project (automatically if possible) in Eclipse/ColdFusion builder. What I envision is instead of checking out a branch via the subversion plugin in CFBuilder/Eclipse, I now use ANT to do that for me. Since I use ColdFusion Builder (Eclipse + Adobe's plugin), I have all of eclipse's tools and plugins available to solve the problem of : how can I best call ANT from within Eclipse/ColdFusion Builder, to setup the local build as a project that I can develop and work on? I think when I check the code back in from the local box, I'd have to be sure not to check in any files with local config paths, etc. I hope this is a detailed and clear enough explanation, if not, please ask. Thanks in advance!

  • Custom UIView built with Interface Builder accessible/positionable via Interface Builder

    - by Nader
    This shouldn't be this confusing. I have a custom UIView with a bunch on controls on it. UILabels, buttons, etc. I've created this Nib using Interface Builder. I want to be able to position this custom uiview on another UIView using the interface builder. How do I link my UIView custom class, to the nib? initWithCoder gets called, but I want this class to get loaded from the nib. Thanks

  • Unable to add datasource in ColdFusion 9 and SQL Server 2008 R2

    - by Evik James
    I just installed SQL Server 2008 R2 and ColdFusion 9.0.1 on my Windows 7 machine for development use only. I have ColdFusion running well and serving pages (that aren't connected to a database). I can view my databases in SQL Server Management Studio. I successfully restored a few small databases and now I am trying to set up datasources for them through the ColdFusion Administrator. On my other machine, this was super easy. Not so much this time. The database I just added is named "Test". I am getting this error: Connection verification failed for data source: Test java.sql.SQLNonTransientConnectionException: [Macromedia][SQLServer JDBC Driver]Error establishing socket to host and port: localhost:1433. Reason: Connection refused: connect The root cause was that: java.sql.SQLNonTransientConnectionException: [Macromedia][SQLServer JDBC Driver]Error establishing socket to host and port: localhost:1433. Reason: Connection refused: connect It looks like the connection between ColdFusion and SQL Server is being refused. I know, brilliant observation, right? On my other machine, I was able to create datasources with just the default settings, no server name, username, or password. Any clue as to what might be the cause and how I might fix it?

  • Using the new CSS Analyzer in JavaFX Scene Builder

    - by Jerome Cambon
    As you know, JavaFX provides from the API many properties that you can set to customize or make your components to behave as you want. For instance, for a Button, you can set its font, or its max size.Using Scene Builder, these properties can be explored and modified using the inspector. However, JavaFX also provides many other properties to have a fine grained customization of your components : the css properties. These properties are typically set from a css stylesheet. For instance, you can set a background image on a Button, change the Button corners, etc... Using Scene Builder, until now, you could set a css property using the inspector Style and Stylesheet editors. But you had to go to the JavaFX css documentation to know the css properties that can be applied to a given component. Hopefully, Scene Builder 1.1 added recently a very interesting new feature : the CSS Analyzer.It allows you to explore all the css properties available for a JavaFX component, and helps you to build your css rules. A very simple example : make a Button rounded Let’s take a very simple example:you would like to customize your Buttons to make them rounded. First, enable the CSS Analyzer, using the ‘View->Show CSS Analyzer’ menu. Grow the main window, and the CSS Analyzer to get more room: Then, drop a Button from the Library to the ContentView: the CSS Analyzer is now showing the Button css properties: As you can see, there is a ‘-fx-background-radius’ css property that allow to define the radius of the background (note that you can get the associated css documentation by clicking on the property name). You can then experiment this by setting the Button style property from the inspector: As you can see in the css doc, one can set the same radius for the 4 corners by a simple number. Once the style value is applied, the Button is now rounded, as expected.Look at the CSS Analyzer: the ‘-fx-background-radius’ property has now 2 entries: the default one, and the one we just entered from the Style property. The new value “win”: it overrides the default one, and become the actual value (to highlight this, the cell background becomes blue). Now, you will certainly prefer to apply this new style to all the Buttons of your FXML document, and have a css rule for this.To do this, save you document first, and create a css file in the same directory than the new document.Create an empty css file (e.g. test.css), and attach it the the root AnchorPane, by first selecting the AnchorPane, then using the Stylesheets editor from the inspector: Add the corresponding css rule to your new test.css file, from your preferred editor (Netbeans for me ;-) and save it. .button { -fx-background-radius: 10px;} Now, select your Button and have a look at the CSS Analyzer. As you can see, the Button is inheriting the css rule (since the Button is a child of the AnchorPane), and still have its inline Style. The Inline style “win”, since it has precedence on the stylesheet. The CSS Analyzer columns are displayed by precedence order.Note the small right-arrow icons, that allow to jump to the source of the value (either test.css, or the inspector in this case).Of course, unless you want to set a specific background radius for this particular Button, you can remove the inline Style from the inspector. Changing the color of a TitledPane arrow In some cases, it can be useful to be able to select the inner element you want to style directly from the Content View . Drop a TitledPane to the Content View. Then select from the CSS Analyzer the CSS cursor (the other cursor on the left allow you to come back to ‘standard’ selection), that will allow to select an inner element: height: 62px;" align="LEFT" border="0"> … and select the TitledPane arrow, that will get a yellow background: … and the Styleable Path is updated: To define a new css rule, you can first copy the Styleable path : .. then paste it in your test.css file. Then, add an entry to set the -fx-background-color to red. You should have something like: .titled-pane:expanded .title .arrow-button .arrow { -fx-background-color : red;} As soon as the test.css is saved, the change is taken into account in Scene Builder. You can also use the Styleable Path to discover all the inner elements of TitledPane, by clicking on the arrow icon: More details You can see the CSS Analyzer in action (and many other features) from the Java One BOF: BOF4279 - In-Depth Layout and Styling with the JavaFX Scene Builder presented by my colleague Jean-Francois Denise. On the right hand, click on the Media link to go to the video (streaming) of the presa. The Scene Builder support of CSS starts at 9:20 The CSS Analyzer presentation starts at 12:50

  • Can Azure host ColdFusion?

    - by mbursill
    A friend has a site developed in ColdFusion with MySQL and is looking for better cost-effective hosting as the traffic scales up rapidly. Azure comes to mind. I haven't used Azure myself, however, I believe it is possible to setup and interact with the web-server via RDP into a hosted Virtual Machine? I am curious if ColdFusion can be installed in the hosted Azure VM. Also, would the site have to be tweaked to run on Azure SQL, or could it continue to use MySQL? Thanks.

  • How can I move from Java and ColdFusion to Ruby on Rails?

    - by Ciaran Archer
    Currently I work with ColdFusion 9+ and some Java in a Windows environment. Prior to ColdFusion, my background was in Java and JSP. I'm considering a move towards Ruby on Rails, as I think it would be a real challenge, keep things fresh, and provide more job opportunities. In order to get into it, I started to build my personal website in Rails 3.0. But what else can I do to make this transition from what I know now to Ruby and Rails? Are there specific or idiomatic aspects of Ruby or Rails I should keep in mind when switching over from a ColdFusion and Java mindset?

  • Huge performance difference between two web servers, odd behavior seen using process monitor

    - by Francis Gagnon
    We have two Coldfusion servers that have a huge performance difference running the exact same code on the exact same input data. The code in questions instantiates a large amount of CFCs (Coldfusion Components, which are similar to objects in OOP languages). I compared the two servers by running Process Monitor and then calling the problematic code on both machines. I learned two things. First, Coldfusion opens CFC files every time it instantiates an object. Both servers do this, so it cannot be the cause of the performance difference. Second, the fast server opens the CFC files directly while the server with the performance problem seems to navigate its way through the path until it reaches the desired CFC file. It does this for every file, even the ones it has previously loaded, and because the code instantiates so many CFCs it becomes very slow. See below the partial Promon traces that show this behavior. It can take over 60 seconds for the slow server to do what the fast one does in 2 seconds. Can anyone tell me what causes this behavior? Is it a Coldfusion setting? Since Coldfusion runs on top of Java, is it a Java setting? Is it an OS option? The fast server is running Windows XP and I think the slow server is a Windows Server 2003. Bonus question: Coldfusion doesn't seem to perform any READ FILE operations on any of the CFC or CFM files. How can this be? Sample of the fast server opening CFC files: 11:25:14.5588975 jrun.exe QueryOpen C:\CF\wwwroot\APP\com\HtmlUtils.cfc 11:25:14.5592758 jrun.exe CreateFile C:\CF\wwwroot\APP\com\HtmlUtils.cfc 11:25:14.5595024 jrun.exe QueryBasicInformationFile C:\CF\wwwroot\APP\com\HtmlUtils.cfc 11:25:14.5595940 jrun.exe CloseFile C:\CF\wwwroot\APP\com\HtmlUtils.cfc 11:25:14.5599628 jrun.exe CreateFile C:\CF\wwwroot\APP\com\HtmlUtils.cfc 11:25:14.5601600 jrun.exe QueryBasicInformationFile C:\CF\wwwroot\APP\com\HtmlUtils.cfc 11:25:14.5602463 jrun.exe CloseFile C:\CF\wwwroot\APP\com\HtmlUtils.cfc Equivalent sample of the slow server opening CFC files: 11:15:08.1249230 jrun.exe CreateFile D:\ 11:15:08.1250100 jrun.exe QueryDirectory D:\org 11:15:08.1252852 jrun.exe CloseFile D:\ 11:15:08.1259670 jrun.exe CreateFile D:\org 11:15:08.1260319 jrun.exe QueryDirectory D:\org\cli 11:15:08.1260769 jrun.exe CloseFile D:\org 11:15:08.1269451 jrun.exe CreateFile D:\org\cli 11:15:08.1270613 jrun.exe QueryDirectory D:\org\cli\cpn 11:15:08.1271140 jrun.exe CloseFile D:\org\cli 11:15:08.1279312 jrun.exe CreateFile D:\org\cli\cpn 11:15:08.1280086 jrun.exe QueryDirectory D:\org\cli\cpn\APP 11:15:08.1280789 jrun.exe CloseFile D:\org\cli\cpn 11:15:08.1291034 jrun.exe CreateFile D:\org\cli\cpn\APP 11:15:08.1291709 jrun.exe QueryDirectory D:\org\cli\cpn\APP\com 11:15:08.1292224 jrun.exe CloseFile D:\org\cli\cpn\APP 11:15:08.1300568 jrun.exe CreateFile D:\org\cli\cpn\APP\com 11:15:08.1301321 jrun.exe QueryDirectory D:\org\cli\cpn\APP\com\HtmlUtils.cfc 11:15:08.1301843 jrun.exe CloseFile D:\org\cli\cpn\APP\com 11:15:08.1312049 jrun.exe CreateFile D:\org\cli\cpn\APP\com\HtmlUtils.cfc 11:15:08.1314409 jrun.exe QueryBasicInformationFile D:\org\cli\cpn\APP\com\HtmlUtils.cfc 11:15:08.1314633 jrun.exe CloseFile D:\org\cli\cpn\APP\com\HtmlUtils.cfc 11:15:08.1315881 jrun.exe CreateFile D:\ 11:15:08.1316379 jrun.exe QueryDirectory D:\org 11:15:08.1316926 jrun.exe CloseFile D:\ 11:15:08.1330951 jrun.exe CreateFile D:\org 11:15:08.1338656 jrun.exe QueryDirectory D:\org\cli 11:15:08.1339118 jrun.exe CloseFile D:\org 11:15:08.1526468 jrun.exe CreateFile D:\org\cli 11:15:08.1527295 jrun.exe QueryDirectory D:\org\cli\cpn 11:15:08.1527989 jrun.exe CloseFile D:\org\cli 11:15:08.1531977 jrun.exe CreateFile D:\org\cli\cpn 11:15:08.1532589 jrun.exe QueryDirectory D:\org\cli\cpn\APP 11:15:08.1533575 jrun.exe CloseFile D:\org\cli\cpn 11:15:08.1538457 jrun.exe CreateFile D:\org\cli\cpn\APP 11:15:08.1539083 jrun.exe QueryDirectory D:\org\cli\cpn\APP\com 11:15:08.1539553 jrun.exe CloseFile D:\org\cli\cpn\APP 11:15:08.1544126 jrun.exe CreateFile D:\org\cli\cpn\APP\com 11:15:08.1544980 jrun.exe QueryDirectory D:\org\cli\cpn\APP\com\HtmlUtils.cfc 11:15:08.1545482 jrun.exe CloseFile D:\org\cli\cpn\APP\com 11:15:08.1551034 jrun.exe CreateFile D:\org\cli\cpn\APP\com\HtmlUtils.cfc 11:15:08.1552878 jrun.exe QueryBasicInformationFile D:\org\cli\cpn\APP\com\HtmlUtils.cfc 11:15:08.1553044 jrun.exe CloseFile D:\org\cli\cpn\APP\com\HtmlUtils.cfc Thanks

  • UML Modelling in C++Builder 2010 Professional

    - by Gordon Brandly
    I'd like to do some basic class diagram UML models in the Pro version of C++Builder 2010. Embarcadero has a C++Builder Features Matrix document, one line of which says "UML Code Visualization – at any time, get a UML model view of your source code" and has a check in the "Professional" column of that table -- I assume this means it should be available to me. Yet, when I open an existing project and do a View | Model View, there's nothing in the Model View window. The only diagram I can find is on the Graph tab of the C++ Class Explorer. I wouldn't call that a UML diagram myself -- is that what Embarcadero is referring to? Embarcadero's table shows that many UML diagrams are not available in Pro, but it looks to me like Class Diagrams should be available. Other lines in that same table indicate that both "Full two-way class diagrams with synchronization between code and diagrams" and "Diagram hyper-linking and annotations" are also supposed to be available in Pro. The Class Explorer graph is one-way only as far as I can tell, so I hope they're referring to something else I haven't been able to find so far. Thanks for any insight into this.

  • ColdFusion vs PHP

    - by Drek
    Can anyone share with me (without fervent evangelism, please) any comparative experiences you might have with regard to ColdFusion and PHP in developing internal enterprise browser-based applications? Specifically (but not limited to): 1: Do the rapid-development characteristics of ColdFusion compensate for any performance issues resulting from the additional overhead? 2: Is either particularly suited to individual or team development? 3: Is rapidly developing an application in ColdFusion and then porting it to PHP to improve performance a proposition that only a madman or venture capitalist would consider?

  • Java Builder pattern with Generic type bounds

    - by I82Much
    Hi all, I'm attempting to create a class with many parameters, using a Builder pattern rather than telescoping constructors. I'm doing this in the way described by Joshua Bloch's Effective Java, having private constructor on the enclosing class, and a public static Builder class. The Builder class ensures the object is in a consistent state before calling build(), at which point it delegates the construction of the enclosing object to the private constructor. Thus public class Foo { // Many variables private Foo(Builder b) { // Use all of b's variables to initialize self } public static final class Builder { public Builder(/* required variables */) { } public Builder var1(Var var) { // set it return this; } public Foo build() { return new Foo(this); } } } I then want to add type bounds to some of the variables, and thus need to parametrize the class definition. I want the bounds of the Foo class to be the same as that of the Builder class. public class Foo<Q extends Quantity> { private final Unit<Q> units; // Many variables private Foo(Builder<Q> b) { // Use all of b's variables to initialize self } public static final class Builder<Q extends Quantity> { private Unit<Q> units; public Builder(/* required variables */) { } public Builder units(Unit<Q> units) { this.units = units; return this; } public Foo build() { return new Foo<Q>(this); } } } This compiles fine, but the compiler is allowing me to do things I feel should be compiler errors. E.g. public static final Foo.Builder<Acceleration> x_Body_AccelField = new Foo.Builder<Acceleration>() .units(SI.METER) .build(); Here the units argument is not Unit<Acceleration> but Unit<Length>, but it is still accepted by the compiler. What am I doing wrong here? I want to ensure at compile time that the unit types match up correctly.

  • Improvements to Joshua Bloch's Builder Design Pattern?

    - by Jason Fotinatos
    Back in 2007, I read an article about Joshua Blochs take on the "builder pattern" and how it could be modified to improve the overuse of constructors and setters, especially when an object has a large number of properties, most of which are optional. A brief summary of this design pattern is articled here [http://rwhansen.blogspot.com/2007/07/theres-builder-pattern-that-joshua.html]. I liked the idea, and have been using it since. The problem with it, while it is very clean and nice to use from the client perspective, implementing it can be a pain in the bum! There are so many different places in the object where a single property is reference, and thus creating the object, and adding a new property takes a lot of time. So...I had an idea. First, an example object in Joshua Bloch's style: Josh Bloch Style: public class OptionsJoshBlochStyle { private final String option1; private final int option2; // ...other options here <<<< public String getOption1() { return option1; } public int getOption2() { return option2; } public static class Builder { private String option1; private int option2; // other options here <<<<< public Builder option1(String option1) { this.option1 = option1; return this; } public Builder option2(int option2) { this.option2 = option2; return this; } public OptionsJoshBlochStyle build() { return new OptionsJoshBlochStyle(this); } } private OptionsJoshBlochStyle(Builder builder) { this.option1 = builder.option1; this.option2 = builder.option2; // other options here <<<<<< } public static void main(String[] args) { OptionsJoshBlochStyle optionsVariation1 = new OptionsJoshBlochStyle.Builder().option1("firefox").option2(1).build(); OptionsJoshBlochStyle optionsVariation2 = new OptionsJoshBlochStyle.Builder().option1("chrome").option2(2).build(); } } Now my "improved" version: public class Options { // note that these are not final private String option1; private int option2; // ...other options here public String getOption1() { return option1; } public int getOption2() { return option2; } public static class Builder { private final Options options = new Options(); public Builder option1(String option1) { this.options.option1 = option1; return this; } public Builder option2(int option2) { this.options.option2 = option2; return this; } public Options build() { return options; } } private Options() { } public static void main(String[] args) { Options optionsVariation1 = new Options.Builder().option1("firefox").option2(1).build(); Options optionsVariation2 = new Options.Builder().option1("chrome").option2(2).build(); } } As you can see in my "improved version", there are 2 less places in which we need to add code about any addition properties (or options, in this case)! The only negative that I can see is that the instance variables of the outer class are not able to be final. But, the class is still immutable without this. Is there really any downside to this improvement in maintainability? There has to be a reason which he repeated the properties within the nested class that I'm not seeing?
