  • Facelet components layouts and javascript

    - by Java Drinker
    Hi all, I have a question regarding the placement of javascript within facelet components. This is more regarding best practice/style than a programming issue, but I feel like all the solutions I have thought of have been hacks at best. Ok here is my scenario: I have a facelet template like so (my faces, and apache Trinidad)... <ui:composition> <f:view locale="#{myLocale}"> <ui:insert name="messageBundles" /><!--Here we add load bundle tags--> <tr:document mode="strict" styleClass="coolStyleDoc"> <f:facet name="metaContainer"> <!--This trinidad defined facet is added to HTML head--> <tr:group> <!-- blah bal my own styles and js common to all --> <ui:insert name="metaData" /> </tr:group> </f:facet> <tr:form usesUpload="#{empty usesUpload ? 'false' : usesUpload}"> <div id="formTemplateHeader"> <ui:insert name="contentHeader" /> </div> <div id="formTemplateContentContainer"> <div id="formTemplateContent"> <ui:insert name="contentBody" /> </div> </div> <div id="formTemplateFooter"> <ui:insert name="contentFooter"> </ui:insert> </div> </tr:form> <!-- etc...---> Now, a facelet that wants to use this template would look like the following: <ui:composition template="/path/to/my/template.jspx"> <ui:define name="bundles"> <custom:loadBundle basename="messagesStuff" var="bundle" /> </ui:define> <ui:define name="metaData"> <script> <!-- cool javascript stuff goes here--> </script> </ui:define> <ui:define name="contentHeader"> <!-- MY HEADING!--> </ui:define> <ui:define name="contentBody"> <!-- MY Body!--> </ui:define> <ui:define name="contentFooter"> <!-- Copyright/footer stuff!--> </ui:define> </ui:composition> All this works quite well, but the problem I have is when I want to use a facelet component inside this page. If the facelet component has its own javascript code (jQuery stuff etc), how can I make it so that that javascript code is included in the header section of the generated html? Any help would be appreciated. Please let me know if this is not clear or something... thanks in advance

  • Good books and resources on user interface testing

    - by josefx
    I am looking for good books and articles on user-interface testing. What they should contain (one or more of): different test methods/strategies examples, use cases naming pros and cons for different methods something important I might have forgotten :-) What they should not be: Only about general tests and not gui tests describing a test framework limited to a single language What are the best resources you know of? (preferably language agnostic)

  • Integrating Amazon EC2 in Java via NetBeans IDE

    - by Geertjan
    Next, having looked at Amazon Associates services and Amazon S3, let's take a look at Amazon EC2, the elastic compute cloud which provides remote computing services. I started by launching an instance of Ubuntu Server 14.04 on Amazon EC2, which looks a bit like this in the on-line AWS Management Console, though I whitened out most of the details: Now that I have at least one running instance available on Amazon EC2, it makes sense to use the services that are integrated into NetBeans IDE:  I created a new application with one class, named "AmazonEC2Demo". Then I dragged the "describeInstances" service that you see above, with the mouse, into the class. Then the IDE automatically created all the other files you see below, i.e., 4 Java classes and one properties file: In the properties file, register the access ID and secret keys. These are read by the other generated Java classes. Signing and authentication are done automatically by the code that is generated, i.e., there's nothing generic you need to do and you can immediately begin working on your domain-specific code. Finally, you're now able to rewrite the code in "AmazonEC2Demo" to connect to Amazon EC2 and obtain information about your running instance: public class AmazonEC2Demo { public static void main(String[] args) { String instanceId1 = "i-something"; RestResponse result; try { result = AmazonEC2Service.describeInstances(instanceId1); System.out.println(result.getDataAsString()); } catch (IOException ex) { Logger.getLogger(AmazonEC2Demo.class.getName()).log(Level.SEVERE, null, ex); } } } From the above, you'll receive a chunk of XML with data about the running instance, it's name, status, dates, etc. In other words, you're now ready to integrate Amazon EC2 features directly into the applications you're writing, without very much work to get started. Within about 5 minutes, you're working on your business logic, rather than on the generic code that anyone needs when integrating with Amazon EC2.

  • Best logging framework for native C++?

    - by Jox
    I'm looking for logging framework for C++ project. My best shoot was log4cxx, but it seems that it's abandoned project, with development stopped ~4 years ago, with only one update in last 4-5 years. Anything better that log4cxx? (log4c & log4cpp are also totally out-of-date)...

  • iPhone SDK development obj-C vs interface builder

    - by Amy
    I'm new to the iOS platform. I'm not clear on the purpose of the interface builder. It looks like I can avoid using it entirely and just write all the code in objective c. am I right? is there anything that IB can do but obj-c cannot? It reminds me of visual basic 6.

  • JavaOne 2012 in Review

    - by Janice J. Heiss
    Noted freelance writer Steve Meloan has a new article up on otn/java, titled, “JavaOne 2012 Review: Make the Future Java” in which he summarizes the happenings at JavaOne 2012. Along the way, he reminds us that if the future turns out to be anything like the past, Java will do fine: The repeated theme for this year's conference was ‘Make the Future Java,’ and according to recent stats, the groundwork is already firmly in place:    There are 9 million Java developers worldwide.    Three billion devices run Java.    Five billion Java Cards are in use.    One hundred percent of Blu-ray Disc players ship with Java.    Ninety-seven percent of enterprise desktops run Java.    Eighty-nine percent of PC desktops run Java.This year's content curriculum program was organized under seven technical tracks:    Core Java Platform    Development Tools and Techniques    Emerging Languages on the JVM    Enterprise Service Architectures and the Cloud    Java EE Web Profile and Platform Technologies    Java ME, Java Card, Embedded, and Devices    JavaFX and Rich User Experiences”Meloan artfully reminds us of how JavaOne makes learning fun. Have a look at the article here.

  • How do I prevent a pair of XMLEvent[Reader|Writer] from splitting empty tags into start+end tags?

    - by java.is.for.desktop
    Hello, everyone! I have an understanding problem of how the following code works: XMLInputFactory xif = XMLInputFactory.newFactory(); XMLOutputFactory xof = XMLOutputFactory.newFactory(); XMLEventReader reader = xif.createXMLEventReader(/* ... */); XMLEventWriter writer = xof.createXMLEventWriter(/* ... */); writer.add(reader); The method writer.add([some reader]) reads all events from reader and writes them consequently. Sadly, following happens: The input <root><c/></root> gets transformed to <root><c><c/></root> I know, from XML point of view, these are equal trees, but not for a human ;) What can I do to get the same output? FYI: I need a XMLEvent[Reader|Writer] pair later to filter "XML events".

  • JavaCC: How can I specify which token(s) are expected in certain context?

    - by java.is.for.desktop
    Hello, everyone! I need to make JavaCC aware of a context (current parent token), and depending on that context, expect different token(s) to occur. Consider the following pseudo-code: TOKEN <abc> { "abc*" } // recognizes "abc", "abcd", "abcde", ... TOKEN <abcd> { "abcd*" } // recognizes "abcd", "abcde", "abcdef", ... TOKEN <element1> { "element1" "[" expectOnly(<abc>) "]" } TOKEN <element2> { "element2" "[" expectOnly(<abcd>) "]" } ... So when the generated parser is "inside" a token named "element1" and it encounter "abcdef" it recognizes it as <abc>, but when its "inside" a token named "element2" it recognizes the same string as <abcd>. element1 [ abcdef ] // aha! it can only be <abc> element2 [ abcdef ] // aha! it can only be <abcd> If I'm not wrong, it would behave similar to more complex DTD definitions of an XML file. So, how can one specify, in which "context" which token(s) are valid/expected? NOTE: It would be not enough for my real case to define a kind of "hierarchy" of tokens, so that "abcdef" is always first matched against <abcd> and than <abc>. I really need context-aware tokens.

  • Installing Java ME SDK Plugin for NetBeans is now much easier!

    - by SungmoonCho
    The other day, I wrote about how to download and install Java ME SDK plugin for NetBeans. If you are using NetBeans 7.2.1 or later, you don't have to go through the whole process at all. It's now a matter of a few clicks, because all the plugins are now all in NetBeans update server. Here is a new way to install and integrate Java ME SDK plugins for NetBeans. 1. On NetBeans, go to "Tools"- "Plugins". 2. Click on "Available Plugins" tab. Locate "Java ME SDK Tools". 3. Check the tools you want to install, and click "Install" button at the bottom left corner. 4. NetBeans will restart, and that's it! Remember that different Java ME SDK requires different version of Plugins. If you are using Java ME SDK 3.0.5 or earlier, you must install Java ME SDK Tool version 2.0 (works with NetBeans 7.1.2 or earlier) If you are using Java ME SDK 3.2 or later, you must install Java ME SDK Tool version 3.0 (works with NetBeans 7.2 or later)

  • Call methods on native Javascript types without wrapping with ()

    - by Anurag
    In Javascript, we can call methods on string literals directly without enclosing it within round brackets. But not for other types such as numbers, or functions. It is a syntax error, but is there a reason as to why the Javascript lexer needs these other types to be enclosed in round brackets? For example, if we extend Number, String, and Function with an alert method and try calling this method on the literals, it's a SyntaxError for Number and Function, while it works for a String. function alertValue() { alert(this); } Number.prototype.alert = alertValue; String.prototype.alert = alertValue; Function.prototype.alert = alertValue; We can call alert directly on a string object: "someStringLiteral".alert() // alerts someStringLiteral but it's a SyntaxError on numbers, and functions. 7.alert(); function() {}.alert(); To work with these types, we have to enclose it within brackets: (7).alert(); // alerts "7" (function() {}).alert(); // alerts "function() {}"

  • File name containing more than 16 characters inside parentheses failing

    - by Tom anMoney
    I am generating file names that contain a timestamp in the following format: "base_name (yyyy-mm-dd hhmmss).ext" This seems to cause a problem on Android. Here's my log: /storage/sdcard0/anMoney/transfer/Net worth over time _ Forecast (2012-11-19 110550).pdf E/Gmail (11802): java.io.FileNotFoundException: /storage/sdcard0/myapp/transfer/Net worth over time _ Forecast (2012-11-19 110550).pdf: open failed: ENOENT (No such file or directory) E/Gmail (11802): at libcore.io.IoBridge.open(IoBridge.java:416) E/Gmail (11802): at java.io.FileInputStream.<init>(FileInputStream.java:78) E/Gmail (11802): at java.io.FileInputStream.<init>(FileInputStream.java:105) E/Gmail (11802): at android.content.ContentResolver.openInputStream(ContentResolver.java:445) E/Gmail (11802): at com.google.android.gm.provider.MailEngine.cacheAttachment(MailEngine.java:3054) E/Gmail (11802): at com.google.android.gm.provider.MailEngine.sendOrSaveDraft(MailEngine.java:2746) E/Gmail (11802): at com.google.android.gm.provider.MailProvider.sendOrSaveDraft(MailProvider.java:477) E/Gmail (11802): at com.google.android.gm.provider.MailProvider.insert(MailProvider.java:534) E/Gmail (11802): at android.content.ContentProvider$Transport.insert(ContentProvider.java:201) E/Gmail (11802): at android.content.ContentResolver.insert(ContentResolver.java:864) E/Gmail (11802): at com.google.android.gm.provider.Gmail$MessageModification.sendOrSaveNewMessage(Gmail.java:3576) E/Gmail (11802): at com.google.android.gm.ComposeActivity$SendOrSaveTask$1.onInitializationComplete(ComposeActivity.java:1765) E/Gmail (11802): at com.google.android.gm.provider.MailEngine$5.run(MailEngine.java:1006) E/Gmail (11802): at android.os.Handler.handleCallback(Handler.java:615) E/Gmail (11802): at android.os.Handler.dispatchMessage(Handler.java:92) E/Gmail (11802): at android.os.Looper.loop(Looper.java:137) E/Gmail (11802): at android.os.HandlerThread.run(HandlerThread.java:60) E/Gmail (11802): Caused by: libcore.io.ErrnoException: open failed: ENOENT (No such file or directory) Now, if I trim the file name to have only 16 characters within the parentheses, everything is working as expected. I am able to send the file as a GMail attachment. The following file name is working fine: /storage/sdcard0/myapp/transfer/Net worth over time _ Forecast (2012-11-19 11070).pdf I tried the following troubleshooting: It's not the overall length of the file name, as if I shorten the base name, the same behavior remains It's not GMail, uploading the file to Google Drive fails similarly 16 characters inside the parentheses work, but not 17 It's not the space character inside the parentheses that causes the issue, as I replaced it with a dash and it's the same problem. Anybody has any ideas on what's going on here?

  • Arduino IDE "launch 4j" error

    - by John
    I have a computer running Windows XP. I am trying to run the Arduino IDE 0022. I double-click on arduino.exe, it waits about 30 seconds on the load up title screen, and then it gives me this error: Launch 4j: an error occurred while starting the application My only choice is to click "OK"; the error goes away, and the Arduino IDE closes. If I try to delete the Arduino files (to try overwriting with some different files), I get an error that doesn't allow me to do so: Cannot delete awt.dll: Access denied Make sure the disk is not full or write protected and that the file is not currently in use. The only way to delete the file is by restarting the computer. So something must still be trying to run after that first error. I have noticed in Task Manager that some Java programs are still running: javaw.exe (3 processes) I think this is a problem with Java, but I checked and updated all of my Java software and it is all up to date. I have looked on other forums for this issue and none of them seemed to help. From the forums I have tried: Different Arduino IDE versions Updating Java Opening arduino.exe as Administrator Nothing has worked. Anyone have any suggestions?
