• jQuery - discrepency between classname and selectors

  - by Ciel

  I have the following code that I wrote, which I personally found to be pretty nice. It takes a <ul> and it drops down the contents when clicked. But I am having a disconnect here in comprehension, and one I had to do what I feel is a 'dirty hack' to solve. The problem is that I do not want the class `'sidebar-dropdown-open' to be so 'hardwired' in the plugin. However I discovered that there is a very stark difference between... $('.sidebar-dropdown-open') and 'sidebar-dropdown-open and even '.sidebar-dropdown-open. I 'solved' this problem by including two different 'parameters' in my plugin, but I was wondering if someone might give me some insight as to how I could perform this better, and why this was behaving this way. wiring (document load) $(document).ready(function () { $('[data-role="sidebar-dropdown"]').drawer({ open: 'sidebar-dropdown-open', css: '.sidebar-dropdown-open' }); }); html <ul> <li class=" dropdown" data-role="sidebar-dropdown"> <a href="pages/.." class="remote">Link Text</a> <ul class="sub-menu light sidebar-dropdown-menu"> <li><a class="remote" href="pages/...">Link Text</a></li> <li><a class="remote" href="pages/...">Link Text</a></li> <li><a class="remote" href="pages/...">Link Text</a></li> </ul> </li> </ul> javascript (function ($) { $.fn.drawer = function (options) { // Create some defaults, extending them with any options that were provided var settings = $.extend({ open: 'open', css: '.open' }, options); return this.each(function () { $(this).on('click', function (e) { // slide up all open dropdown menus $(settings.css).not($(this)).each(function () { $(this).removeClass(settings.open); // retrieve the appropriate menu item var $menu = $(this).children(".dropdown-menu, .sidebar-dropdown-menu"); // slide down the one clicked on. $menu.slideUp('fast'); $menu.removeClass('active'); }); // mark this menu as open $(this).addClass(settings.open); // retrieve the appropriate menu item var $menu = $(this).children(".dropdown-menu, .sidebar-dropdown-menu"); // slide down the one clicked on. $menu.slideDown(100); $menu.addClass('active'); e.preventDefault(); e.stopPropagation(); }).on("mouseleave", function () { $(this).children(".dropdown-menu").hide().delay(300); }); }) }; })(jQuery); I have tried using settings.open and demanding that it just be a className (.open), etc. - but that does not seem to work. It seems to get ignored by the removeClass function.

• Coordinate and positioning problem on iOS with cocos2d-x

  - by Vexille

  I'm using cocos2d-x alongside with Marmalade and running some tests and tutorials before starting an actual project with them. So far things are working reasonably well on the windows simulator, Android and even on Blackberry's Playbook, but on iOS devices (iPhone and iPad) the positioning seems to be off. To make things clearer, I put together a scene that just draws an image in the middle of the screen. It worked as expected on everything else, but this is the result I got on an iPhone: To get the coordinates for the center of the screen I'm using the VisibleRect class from the TestCpp sample. It just uses sharedOpenGLView to get the visible size and visible origin, and calculate the center from that. CCSprite* test = CCSprite::create("Ball.png", CCRectMake(0, 0, 80, 80) ); test->setPosition( ccp(VisibleRect::center().x, VisibleRect::center().y) ); this->addChild(test); Also I have a noBorder policy set on AppDelegate: CCEGLView::sharedOpenGLView()->setDesignResolutionSize(designSize.width, designSize.height, kResolutionNoBorder); One funny thing is that I tried to deploy the TestCpp sample project to some iOS devices and it worked reasonably well on the iPhone, but on the iPad the application was only being drawn on a small portion of the screen - just like what happened on the iPhone when I tried using the ShowAll policy.

• JDeveloper News &ndash; Did You Know

  - by shay.shmeltzer

  There have been a few issues lately with access to blogs.oracle.com to write new messages – and as a result I’m a little behind on reporting the latest and greatest in JDeveloper. (I’m also unable to approve comments :-( ) But just in case you missed it here are a few note worthy things you should know: ADF Mobile Client went production – this is a solution that let you use ADF to develop on-device applications for mobile devices. You develop once and run on various devices (right now Blackberry and Windows Mobile with other platforms coming soon). For more information check out the ADF Mobile page on OTN. ADF Developer Certification goes production – you can now take the official test and get an official certification that you can include in your resume.Should be a must for any consultant looking to get ADF related gigs. Learn more about the ADF Certification Exam. ADF Vision Stencils Released – If you are looking for a quick way to draw prototypes of ADF screens you probably can’t get any faster and more accurate results than this. This is a set of Vision components that you can drag over and design a page visually. You can also set properties for components and do other advance things. You do need a license for Visio to use this, but the ADF stencils are free. We’ve been using these internally at Oracle for some time now and we thought the ADF community would enjoy these too. Download the ADF Visio Stencils here (and watch a youtube demo of how they work).

• How to Integrate Dropbox with Pages, Keynote, and Numbers on iPad

  - by The Geek

  The iWork apps are some of the best apps on the iPad, and each show just how powerful a touchscreen device can be with the most basic of computing functions. In fact, there’s not much to dislike about the iWork apps, except for one thing: importing and exporting files. You can open documents from email attachments, download them from websites, or import them from other apps like Dropbox. Once you’ve opened your file in Pages, Keynote, or Numbers on iPad, though, you can only send it via email, upload it to a WebDAV server or Apple’s iDisk service, or wait to sync it with iTunes on your computer. Most other iOS office apps don’t offer nearly as many features as the iWork apps, but they do offer deep integration with Dropbox which makes it easy to view and edit your documents no matter where you are. Dropbox is the most popular file sync and sharing solution, and makes it absolutely painless to share folders with anyone around the world and keep your computers in sync. That is, computers and applications that integrate with Dropbox. However, you don’t need to give up on using Dropbox with iWork apps on iPad. Today we’re going to look at how you can enable WebDAV compatibility on your Dropbox account to let Pages integrate nearly the whole way with Dropbox. It’s not a perfect solution, but it’s much better than the default setup. So let’s get started Latest Features How-To Geek ETC How to Integrate Dropbox with Pages, Keynote, and Numbers on iPad RGB?

• What apps are available for smartphone platforms to allow free calling to the UK and other countries? [closed]

  - by Andrew Ferrier

  On the iPhone, I use MagicJack to get completely free calls over WiFi to US numbers. I'm looking for a similar app to enable me to call UK numbers for free on the iPhone. Does anyone know of one? To make this question of broader applicability to everyone, what apps also allow free calling to other countries? Any smartphone platform (iPhone, Android, Blackberry, Windows Phone) could be useful. Note: I'm talking only about apps that allow completely free calling - the Apple app stores at least are full of apps that allow "cheap" calling. Suspicious apps that require credit card numbers upfront, etc., aren't as interesting.

• nginx caching per user agent

  - by Tuinslak

  I'm currently using nginx as reverse proxy with caching enabled. However, the main site has two different layouts, depending on the user-agent (mobile or not). I've tried something similar to this: # mobile users if ($http_user_agent ~* '(iPhone|iPod|mobile|Android|2.0\ MMP|240x320|AvantGo|BlackBerry|Blazer|Cellphone|Danger|DoCoMo|Elaine/3.0|EudoraWeb|hiptop|IEMobile)') { set $iphone_request '1'; } if ($iphone_request = '1') { proxy_cache mobile; } if ($iphone_request = '') { proxy_cache site; } proxy_cache_key "$scheme://$host$request_uri"; proxy_pass http://real-site.tld; However, nginx gives an error, stating proxy_cache can't be used in an if-structure. Any other way to serve from a different cache depending on the browser? Thanks, Tuinslak

• Is there a Google Authenticator desktop client?

  - by cwd

  I am using Google Authenticator for 2-step authentication. I like how I can use a code and verify my account using my phone: I realize that the app was designed to run on a device other than a computer to increase security for the computer (in case that it is lost or stolen), but I would like to know if there is a way I can run Google Authenticator on my Macbook. Now, per the Google Authenticator Page it will not run on a desktop: What devices does Google Authenticator work on? Android version 2.1 or later BlackBerry OS 4.5 - 6.0 iPhone iOS 3.1.3 or later However there are several emulators for developers and so I wonder if it is possible to run one of these emulators and then run Google Authenticator with that. I do realize this is not a best practice - but I'm less worried about my laptop getting stolen and more worried about someone just hacking the account. So my question is this: Is it possible to run it on the desktop, even though it is not meant to be / not recommended?

• Java jasper report NullPointerException

  - by William Welch

  I am new to Java and I am running into this issue that I can't figure out. I inherited this project and I have the following code in one of my scriptlets: DefaultLogger.logMessage("DEBUG path: "+ reportFile.getPath()); DefaultLogger.logMessage("DEBUG parameters: "+ parameters); DefaultLogger.logMessage("DEBUG jr: "+ jr); bytes = JasperRunManager.runReportToPdf(reportFile.getPath(), parameters, jr); And I am getting the following results (the fourth line there is line 287 in FootwearReportsServlet.doGet): DEBUG path: C:\Development\JavaWorkspaces\Workspace1\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\RSLDevelopmentStandard\reports\templates\footwear\RslFootwearReport.jasper DEBUG parameters: {class_list_subreport=net.sf.jasperreports.engine.JasperReport@b07af1, signature_path=images/logo_reports.jpg, submission_id=20070213154168780, test_results_subreport=net.sf.jasperreports.engine.JasperReport@5795ce, logo_path=images/logos_3.gif, report_connection_secondary=com.mysql.jdbc.JDBC4Connection@2c39d2, testing_packages_subreport=net.sf.jasperreports.engine.JasperReport@1883d5f, signature_path2=images/logo_reports.jpg, tpid_subreport=net.sf.jasperreports.engine.JasperReport@17531fd, first_page_subreport=net.sf.jasperreports.engine.JasperReport@12504e0} DEBUG jr: net.sf.jasperreports.engine.data.JRMapCollectionDataSource@1630eb6 Apr 29, 2010 4:15:13 PM org.apache.catalina.core.StandardWrapperValve invoke SEVERE: Servlet.service() for servlet FootwearReportsServlet threw exception java.lang.NullPointerException at net.sf.jasperreports.engine.fill.JRFiller.fillReport(JRFiller.java:89) at net.sf.jasperreports.engine.JasperFillManager.fillReport(JasperFillManager.java:601) at net.sf.jasperreports.engine.JasperFillManager.fillReport(JasperFillManager.java:517) at net.sf.jasperreports.engine.JasperRunManager.runReportToPdf(JasperRunManager.java:385) at com.rsl.reports.FootwearReportsServlet.doGet(FootwearReportsServlet.java:287) at javax.servlet.http.HttpServlet.service(HttpServlet.java:617) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:852) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:588) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) at java.lang.Thread.run(Unknown Source) What I can't figure out is where the null reference is. From the debug lines I can see that each parameter has a value. Could it be referring to a bad path to one of the images? Any ideas? For some reason my server won't start in debug mode in Eclipse so I am having trouble figuring this out.

• Solr DataImportHandler configuration

  - by talo

  I want to get data from mysql database with the help of DataImportHandler so i can create indexes. Now I've configured my Solr instance so that it works on Tomcat (the example admin page), but if I try to change the sorlconfig.xml file i'll get the error message. I'm working with Solr 3.6 So my configuration is: In solrconfig.xml i added: <dataDir>${solr.data.dir:/usr/share/tomcat7/solr2}</dataDir> to specify my working directory and then <requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler"> <lst name="defaults"> <str name="config">/usr/share/tomcat7/solr2/conf/data-config.xml</str> </lst> </requestHandler> to specify new request handler. Theese two are my lib directives for DIH. Do i need to change them? <lib dir="../../dist/" regex="apache-solr-dataimporthandler-\d.*\.jar" /> <lib dir="../../contrib/dataimporthandler/lib/" regex=".*\.jar" /> I also created data-config.xml file and added following: <?xml version="1.0" encoding="UTF-8"?> <dataConfig> <dataSource type="JdbcDataSource" driver="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost:3306/ethicsweb_experts" user="root" password=""/> <document> <entity name="experts" datasource="mysql" pk="mainid" query="SELECT experts.mainid as mainid FROM experts WHERE validRec = 'y'"> <field column="mainid" name="mainid"/> <field column="validRec" name="validRec"/> </entity> </document> I've coppied following jars to tomcat/lib folder (DIH jar files and mysql JDBC connector jar file) apache-solr-dataimporthandler-3.6.0.jar apache-solr-dataimporthandler-extras-3.6.0.jar mysql-connector-java-5.1.20-bin.jar Also in the schema.xml file i added folowing fields: <field name="mainid" type="int" indexed="true" stored="true" /> <field name="validRec" type="string" indexed="true" stored="true" /> <field name="recSource" type="string" indexed="true" stored="true" /> <uniqueKey>mainid</uniqueKey> But now when i try to acces: http://localhost:8080/solr2/ I get following output: HTTP Status 500 - Severe errors in solr configuration. Check your log files for more detailed information on what may be wrong.

• Managing a file-based public maven repository

  - by Roland Ewald

  I am looking for an easy way to manage a public file-based Maven repository. While we are using the open-source version of Artifactory internally, we now want to put a file-based repository of our published artifacts (and their dependencies) on a separate machine that is publicly available. There are several ways how to do this, but none of them seems ideal: Use Maven Dependency plugin: if it is configured correctly and executed with the goal dependency:copy-dependencies for the release-module of our project, it creates a local repository structure that is fine, but this structure does not contain the meta-data.xml files, nor the hash-sums. Use Artifactory to export repo: AFAIK Artifactory only allows to export a repository as a whole. This would include the non-published modules from our project (which would then need to be deleted manually). Also, all dependencies are sitting in another repository, so this needs to be done twice, and many dependencies are not even required by a published artifact (only by artifacts that are still for internal use only). Nevertheless, this method would also include the meta-data.xml files and the hash-sums for all files. To set up an initial version of the repository, I used a mixture of both methods: I first created the Maven repository for all required dependencies via dependency:copy-dependencies and then wrote a script to cherry-pick the meta-data.xml files (etc.) from Artifactory. This is terribly cumbersome, isn't there a better way to solve this? Maybe there is another Maven 3 - plugin that I am unaware of, or some other command-line tool that does the job? I basically just need a simple way to create a Maven repository that contains all artifacts a given artifact depends on (and no more), and also contains all meta-data expected in a remote repository. Any ideas?

• jQuery autocomplete - update options on dynamically created elements

  - by Ian Robinson

  Background The user enters values into multiple inputs on the page. Think of entering a list of widgets for sale. The user would select the type of a widget from a drop down. Then enter the name of the Widget vendor, and then the actual name of the widget. These UI elements would all appear as one row. The user is able to click an "add another widget" link and a new row is created. The two input elements have autocomplete functionality attached to them using the DevBridge jQuery plugin. It suggests the name of the vendor and the name of the widget. I have recently wired up the logic to filter the name of the widget based on the name of the vendor you entered. This means setting the (custom) vendorName parameter when attaching the autocomplete plugin so it can be passed to the server side to retrieve the widget names for that vendor that match the name the user entered. To achieve this functionality I'm dynamically attaching the autocomplete functionality to the second element (the widget name text box) when it receives focus. Here is an example: $('.autocomplete-widget').live('focus', function () { $(this).autocomplete({ serviceUrl: '/something.ashx', params: { type: 'widget', vendorName: $(this).parent().prev().find('.autocomplete-vendor').val()} }); }); Problem At first glance, this looks to function quite well. However I started noticing some inconsistencies, and upon inspection, I found out that the call to the server is actually happening several times in some cases. Each time the widget name input element receives focus the autocomplete functionality is attached. And what I'm seeing is that the call to the server is made in proportion to how many times the input element has gained focus. I'd like to avoid making the call more than once, but retain the ability to attach (or update) the autocomplete functionality "on focus". I've tried to use the autocomplete 'setOptions' method but have only been able to get it to work with the static elements, not the dynamically created elements. Question Is there a way I can clear out the autocomplete functionality before I attach another one?

• How to populate Java (web) application with initial data using Spring/JPA/Hibernate

  - by Tuukka Mustonen

  I want to setup my database with initial data programmatically. I want to populate my database for development runs, not for testing runs (it's easy). The product is built on top of Spring and JPA/Hibernate. Developer checks out the project Developer runs command/script to setup database with initial data Developer starts application (server) and begins developing/testing then: Developer runs command/script to flush the database and set it up with new initial data because database structures or the initial data bundle were changed What I want is to setup my environment by required parts in order to call my DAOs and insert new objects into database. I do not want to create initial data sets in raw SQL, XML, take dumps of database or whatever. I want to programmatically create objects and persist them in database as I would in normal application logic. One way to accomplish this would be to start up my application normally and run a special servlet that does the initialization. But is that really the way to go? I would love to execute the initial data setup as Maven task and I don't know how to do that if I take the servlet approach. There is somewhat similar question. I took a quick glance at the suggested DBUnit and Unitils. But they seem to be heavily focused in setting up testing environments, which is not what I want here. DBUnit does initial data population, but only using xml/csv fixtures, which is not what I'm after here. Then, Maven has SQL plugin, but I don't want to handle raw SQL. Maven also has Hibernate plugin, but it seems to help only in Hibernate configuration and table schema creation (not in populating db with data). How to do this?

• Android: Create spinner programmatically from array

  - by Select0r

  Hi, I'm all new to Android and I'm trying to create a spinner programmatically and feeding it with data from an array, but Eclipse gives me a warning that I can't handle. Here's what I got: This ArrayList holds the elements that should be in the spinner (gets filled from a file later on): ArrayList<String> spinnerArray = new ArrayList<String>(); This is code I found on a site which should create the spinner: Spinner spinner = new Spinner(this); ArrayAdapter spinnerArrayAdapter = new ArrayAdapter(this, android.R.layout.simple_spinner_dropdown_item, spinnerArray); spinner.setAdapter(spinnerArrayAdapter); Now the second line (ArrayAdapter...) gives me a warning in Eclipse saying "ArrayAdapter is a raw type... References to generic type ArrayAdapter<T> should be parameterized", I have no idea how to fix this (or what that means in the first place :) ). It's just a warning and the App seems to run alright, but I'd still like to understand what's wrong and fix it. Any hint is appreciated. Greetings, Select0r

• WSDLs generated by Axis2 services can't be read by SoapUI or WSDL2Java

  - by RJCantrell

  I'm converting some services from Apache SOAP to Axis2, so the Java service classes already exist. I created a new project in Eclipse, imported the source, made sure that the Axis2 project facets were installed, and Axis2 emitter properties are correct. Then, in Eclipse, I selected the service class and chose "Create Web Service," choosing the Axis2 runtime. The service is up and running on my PC, and when I append "?wsdl" to the service's path, I do indeed get a WSDL that I save locally. Attempting to import this into SoapUI to build a client gives the error: ERROR:org.apache.xmlbeans.XmlException: C:\projects\soapUI\Axis2\DALService.wsdl:0: error: src-resolve: type 'SOAPException@http://www.w3.org/2001/XMLSchema' not found. The type it's referring to (SOAPException) is a holdover from the Apache SOAP services, and in the service code, I changed all "import" references in the service code (not the WSDL) from org.apache.soap.SOAPException (the old Apache SOAP package name) to javax.xml.soap.SOAPException (the Axis2 location). The code compiles and works, once I can access it, but I can't access it without generating a client. Any thoughts as to why changing the namespace of an object would keep the generated WSDLs from having the proper namespace references?

• Spring Test / JUnit problem - unable to load application context

  - by HDave

  I am using Spring for the first time and must be doing something wrong. I have a project with several Bean implementations and now I am trying to create a test class with Spring Test and JUnit. I am trying to use Spring Test to inject a customized bean into the test class. Here is my test-applicationContext.xml: <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="............."> <bean id="MyUuidFactory" class="com.myapp.UuidFactory" scope="singleton" > <property name="typeIdentifier" value="CLS" /> </bean> <bean id="ThingyImplTest" class="com.myapp.ThingyImplTest" scope="singleton"> <property name="uuidFactory"> <idref local="MyUuidFactory" /> </property> </bean> </beans> The injection of MyUuidFactory instance goes along with the following code from within the test class: private UuidFactory uuidFactory; public void setUuidFactory(UuidFactory uuidFactory) { this.uuidFactory = uuidFactory; } However, when I go to run the test (in Eclipse or command line) I get the following error (stack trace omitted for brevity): Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'MyImplTest' defined in class path resource [test-applicationContext.xml]: Initialization of bean failed; nested exception is org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'java.lang.String' to required type 'com.myapp.UuidFactory' for property 'uuidFactory'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [java.lang.String] to required type [com.myapp.UuidFactory] for property 'uuidFactory': no matching editors or conversion strategy found Funny thing is, the Eclipse/Spring XML editor shows errors of I misspell any of the types or idrefs. If I leave the bean in, but comment out the dependency injection, everything work until I get a NullPointerException while running the test...which makes sense.

• "Pretty" Continuous Integration for Python

  - by dbr

  This is a slightly.. vain question, but BuildBot's output isn't particularly nice to look at.. For example, compared to.. phpUnderControl Hudson CruiseControl.rb ..and others, BuildBot looks rather.. archaic I'm currently playing with Hudson, but it is very Java-centric (although with this guide, I found it easier to setup than BuildBot, and produced more info) Basically: is there any Continuous Integration systems aimed at python, that produce lots of shiney graphs and the likes? Update: After trying a few alternatives, I think I'll stick with Hudson. Integrity was nice and simple, but quite limited. I think Buildbot is better suited to having numerous build-slaves, rather than everything running on a single machine like I was using it. Setting Hudson up for a Python project was pretty simple: Download Hudson from https://hudson.dev.java.net/ Run it with java -jar hudson.war Open the web interface on the default address of http://localhost:8080 Go to Manage Hudson, Plugins, click "Update" or similar Install the Git plugin (I had to set the git path in the Hudson global preferences) Create a new project, enter the repository, SCM polling intervals and so on Install nosetests via easy_install if it's not already In the a build step, add nosetests --with-xunit --verbose Check "Publish JUnit test result report" and set "Test report XMLs" to **/nosetests.xml That's all that's required. You can setup email notifications, and the plugins are worth a look. A few I'm currently using for Python projects: SLOCCount plugin to count lines of code (and graph it!) - you need to install sloccount separately Violations to parse the PyLint output (you can setup warning thresholds, graph the number of violations over each build) Cobertura can parse the coverage.py output. Nosetest can gather coverage while running your tests, using nosetests --with-coverage (this writes the output to **/coverage.xml)

• REST tools support for development and testing

  - by nzpcmad

  There is a similar question here but it only covers some of the issues below. We have a client who requires web services using REST. We have tons of experience using SOAP and over time have gathered together a really good set of tools for SOAP development and testing e.g. soapUI Eclipse plugins wsdl2java WSStudio By "tools" I mean a product "out of the box" that we can start using. I'm not talking about cutting code to "roll our own" using Ajax or whatever. The tool set for REST doesn't seem to be nearly as mature? What tools are out there (we use C# and Java mainly) ? Do the tools handle GET, POST, PUT, and DELETE? Is there a decent Eclipse plugin? Is there a decent client testing application like WSStudio where you point the tool to the WSDL and it generates a proxy on the fly with the appropriate methods and inputs and you simple type the data in? Are there any good package monitoring tools that allow you to look at the data? (I'm not thinking about sniffers like Wireshark here but rather things like soapUI that allow you to see the request / response) ?

• Modify Wordpress SQL Query to pull from within a category

  - by Levi

  Hi I am using a wordpress plugin called "kf most read" which stores a count of how many times a post was read, and lets you output a list of most read posts. This works well. The issue is, I am trying to pull the most read posts, but only the most read posts within the current category you are viewing. I am close to clueless when it comes to sql. Here us what the plugin is currently using to pull the most read posts: $sql = "SELECT count(mr.post_ID) as totHits, p.ID, p.post_title from $wpdb-posts p JOIN {$wpdb-prefix}kf_most_read mr on mr.post_ID = p.ID where mr.hit_ts = '".(time() - ( 86400 * $period))."' GROUP BY mr.post_ID order by totHits desc, ID ASC LIMIT $limit"; How could I incorporate the below query which pulls from a specific category into the above? $sql .= "LEFT JOIN $wpdb-term_taxonomy ON($wpdb-term_relationships.term_taxonomy_id = $wpdb-term_taxonomy.term_taxonomy_id)" ; $sql .= "WHERE $wpdb-term_taxonomy.term_id IN ($currentcat)" ; $sql .= "AND $wpdb-term_taxonomy.taxonomy = 'category'" ; Any Help on this would be much appreciated.

• NoSuchMethod exception thrown in GWT

  - by eb1

  I'm starting to get my feet wet in the latest Google Web Toolkit using the Eclipse plugin on OS X 10.5.8. So far I've been able to get the client up and running, which is great. The server, though, is a different matter. I'm trying to link to a .jar file that has some classes I want to use in a server ServiceImpl class, but it seems to have glommed onto a previous iteration of the .jar - I've added a method, rebuilt the jar, removed the jar from the libraries tab on the GWT project's build path (as well as on the exports) and reincluded the jar. No luck - I'm still getting: [WARN] Exception while dispatching incoming RPC call com.google.gwt.user.server.rpc.UnexpectedException: Service method 'public abstract org.gwtapplication.client.LWDocument org.gwtapplication.client.DocumentService.getDocument()' threw an unexpected exception: java.lang.NoSuchMethodError: org.externalmodel.MyReallyValidClass.toSomething()Ljava/lang/String; at com.google.gwt.user.server.rpc.RPC.encodeResponseForFailure(RPC.java:378) at com.google.gwt.user.server.rpc.RPC.invokeAndEncodeResponse(RPC.java:581) ...
