• Is gchart safe to use?

  - by Paul Tomblin

  The home page for gchart, a client side charting add-in for Google Web Toolkit (GWT), has a long screed about how the project's only maintainer thinks his Google account has been hacked and because of that he will be "disavowing/abandoning my own project and Google account". Does that mean the project is an orphan? Is somebody taking it over? There is always a risk on basing your project on somebody else's code because they may stop supporting it or abandon it during your project's life time, but it seems to me that with the fast evolution of Java and GWT, using gchart in a new project may be a big mistake. Am I right?

• Why isn't Google Web Toolkit more popular?

  - by gerdemb

  I've recently become intrigued with Google Web Toolkit and have started playing with it on some personal projects. I've noticed though that it doesn't seem to be very popular. For example, two major freelancing job boards (www.elance.com and www.odesk.com) list no jobs for GWT and the list of projects using it on Google's official site is pretty slim http://code.google.com/webtoolkit/app_gallery.html (compare to Django projects for example http://www.djangosites.org/). This seems odd to me as GWT has been around since 2006 and is supported by the Google brand name. It also neatly solves the problem of creating cross-browser completely dynamic websites that I haven't seen possible with any other tool. So, why the lack of acceptance?

• Unknown runtime error number: -2146827687

  - by Simone Vellei

  I have an error in my GXT code on Internet Explorer (both Development Mode and not) when i try to attach a label to a panel. The error is "Unknown runtime error number: -2146827687" but this error in a GWT module is throws always, in other gwt modules with a label attached to the panel the error there isn't. The layout of panel is a GridFormLayout developed by me. The error is thrown when the renderComponentInCell is called (the method is called on doLayout) and the component is not rendered (else condition). private void renderComponentInCell(Component component, Element cell) { if (component.isRendered()) { cell.appendChild(component.getElement()); } else { component.render(cell); } } What can I do?

• Get UiBinder widget to display inline instead of block

  - by Steve Armstrong

  I'm trying to get my UiBinder-defined widget to display inline, but I can't. My current code is: <ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder' xmlns:g='urn:import:com.google.gwt.user.client.ui'> <ui:style> .section { border: 1px solid #000000; width: 330px; padding: 5px; display: run-in; } </ui:style> <g:HTMLPanel> <div class="{style.section}"> <div ui:field="titleSpan" class="{style.title}" /> <div class="{style.contents}"> <g:VerticalPanel ui:field="messagesPanel" /> </div> </div> </g:HTMLPanel> </ui:UiBinder> This works fine in terms of how the widget looks internally, but I want to throw a bunch of these widgets into a FlowPanel and have them flow when the window is resized. The HTMLPanel is a div, but I can't get the display attribute to assign. I can't force the style name, since the following throws an error: <g:HTMLPanel styleNames="{style.section}"> And I can assign an additional style, but it doesn't apply the display setting. <g:HTMLPanel addStyleNames="{style.section}"> This displays the border and sets the size, as expected, but it doesn't flow. Firebug shows the styles on the div are border, width, and padding, but no display. Is there a way to make a widget in UiBinder so that it'll display inline instead of block? And if so, can I make it compatible with having a VerticalPanel inside (can I do it without making the entire widget pure HTML without any GWT widgets)? PS: I saw question 2257924 but it hasn't had any answers lately, and he seems to be focused on getting a tag, not specifically getting inline layout. I don't care directly about , if I can just get the top-level tag for my widget to flow inline, I'm happy.

• How to superpose two GwtCanvas ?

  - by Jeep314

  Hi, I'm trying to superpose two GwtCanvas (which use an Html5 canvas). I am able to get this effect by using an absolute panel. But by doing this, I can't get my object to fill my panel. I would like to this so I can do a whiteboard in GWT. So far, I'm pretty advance but I would like to have multiple canvas overlay to support undo or preview. For example, if we draw a rectangle, it would be good to preview it as we move the mouse. I have found a javascript tutorial to do this : ex: http://dev.opera.com/articles/view/html5-canvas-painting/ There is a javascript example, but I'm not sure how to do the bridge between GWT and JavaScript. Any ideas ?

• SmartGWT Widgets not displaying properly

  - by Holograham

  I have a basic GWT Maven project going. I added SmartGWT and started playing around with some widgets and nothing displays correctly. The ListGrid seems to somewhat render but things are off and even data isnt showing up (though the rows respond to indicate there is data within the row). Sorting arrows dont appear but are clickable, and filters are wildy off. Whats causing this. I deleted everything in the .css file. GWT newbie here.

• Learning JavaScript... Should I skip straight to the good stuff (the frameworks)?

  - by Grogs

  I learnt HTML/CSS a good few years back, then PHP a little later. I've recently become interesting in web development again, just started playing with frameworks like Django and RoR. I'm curious as to how much time/effort I should spend learning straight JS before looking at frameworks. I've been reading through a let of articles called Mastering AJAX by Brett McLaughlin which seems quite good, but I'm seeing a lot of stuff (such as cross browser compatibility - even for things like XMLHttpRequest) coming up which look like they would be non-issues if using a framework. So, should I keep reading through these articles and try to build stuff using basic JS, or should I just start looking into jQuery and the like? Also, I've been watching a few videos regarding GWT from Google I/O. I've been learning Java over the last year, built a few medium sized apps in it. I'm wondering if GWT is something that's worth going straight to, along with gQuery?

• Devising a test strategy

  - by Simon Callan

  As part of a new job, I have to devise and implement a complete test strategy for the companies new product. So far, all I really know about it is that it is written in C++, uses an SQL database and has a web API which is used by a browser client written using GWT. As far as I know, there isn't much of an existing strategy, except for using Python scripts to test the web API. I need to develop and implement a suitable strategy for unit, system, regression and release testing, preferably a fully automated one. I'm looking for good references for : Devising the complete test strategy. Testing the web API. Testing the GWT based application. Unit testing C++ code. In addition, any suitable tools would be appreciate

• popup panel that docks to the bottom of the screen

  - by Michael Wiles

  How do I create a pop panel that docks to the bottom of the screen... The way that I'm doing this is by setting the styling as such: bottom: 10px; position: absolute; This will always set the panel to 10 px from the bottom of the browser window. The problem is that gwt (or gwtp for that matter) is insisting on setting the right and the top of the panel and thus overriding my styling. If I use chrome's element explorer and disable the right and top style rules I get the correct behaviour so one way of doing it is somehow disabling gwt setting of the location of the panel on the screen...?

• Client or server side invocation to google API?

  - by Raffo

  I'm writing a web application with GWT and I've to call google calendar's API to retrieve some information. I now have this dilemma: Is it better to use a client side invocation (using javascript or gwt-gdata library) or using the standard google library for java to call the service at server side and then passing all the data to the client via an async call?? I'm not able to understand pros and cons of the two approaches... In particular, I need to call several time the calendar API to retrieve events and let users add new ones, etc. Can you help me?

• Entry points on different urls possible?

  - by user246114

  Hi, I've got a typical gwt project, but am using some url rewriting techniques such that urls entered like: www.mysite.com/johndoe www.mysite.com/janedoe all get served by my main entrypoint project.jsp file. This works great when deployed. When I'm running in hosted mode, it's a total bummer because changing the url in the browser breaks the link with the hosted-mode debugging, such that when I make changes to the source in eclipse and refresh, those changes are not immediately shown. I need to recompile the app and relaunch, and we all know how long that takes. Is there any way to somehow get the hosted-mode environment to recognize that the same webapp is being served on these different urls, and just reconnect the debugging connection? We basically get: http://localhost:8888/myproject.jsp?gwt.codesvr=192.168.1.2:9997 when launching hosted mode, I'd like: http://localhost:8888/johndoe to just reconnect to the debugger, if possible. Thanks

• When and why does an EventHandler require objects to be final?

  - by Michiel Borkent

  I have the following code from a GWT Project that is part of the onModuleLoad() method (similar to Java's main method, if you don't know GWT): final TextBox t1 = new TextBox(); final Label lt1 = new Label(); t1.addKeyUpHandler(new KeyUpHandler() { @Override public void onKeyUp(KeyUpEvent event) { // TODO Auto-generated method stub if (!(t1.getText().matches("\\w{2}-\\w{2}-\\w{2}"))) lt1.setText("Invalid."); else lt1.setText("OK."); } }); Why do the two local variables have to be final here?

• RHEL - NFS4: Mounted/Exported as rw, user write permission denied

  - by brendanmac

  Hello, I have nfs4 configured between a RHEL 5.3 server (charlie) and a RHEL 5.4 client (simcom1). The machines are configured to authenticate users via kerberos by a Windows Server 2008 active directory machine called "alpha." Alpha also serves as a dns and dhcp machine for the local network. I notice that when a user logs in to a RHEL machine for the first time they are issued a unique uid to that machine; The first user to log on gets 10001. So, what I see is that users between simcom1 and charlie have different UIDs. When a user does an 'ls -la' command from within an nfs4 mount I would have thought that the usernames in the owner column would indicate 'nobody' or at least the wrong user name - since UIDs are different between the machines for each user, and not all users have logged into each machine. However, the simcom1 is able to resolve usernames in an 'ls -la' executed on files residing on charlie via nfs4 correctly. Most troubling is that users are unable to write to files across the nfs mount. The server, charlie, has the root directory exported as rw. The client, simcom1, mounts the export as rw. My configurations are shown below. My question is, how do I configure the RHEL machines to allow users to write files across nfs4 that is already mounted as read/write?

• Setup for mounting kerberized nfs home directory - gssd not finding valid kerberos ticket

  - by janm

  Our home directories are exported via kerberized nfs, so the user needs a valid kerberos ticket to be able to mount its home. This setup works fine with our existing clients & server. Now we want to add some 11.10 client and thus set up ldap & kerberos together with pam_mount. The ldap authentication works and users can login via ssh, however their homes can not be mounted. When pam_mount is configured to mount as root, gssd does not find a valid kerberos ticket and the mount fails.

• Ajax, Lizard Brain Web Design, JSF, Struts, JavaScript, Mobile Web, Flash, jQuery, GWT, Harmony at I

  - by Kim Won

  Great Indian Developer Summit 2010 – India's Biggest Polyglot Conference and Workshops for IT Software Professionals Bangalore, April 9, 2010: The GIDS.Web Conference and Workshops has announced the complete program of over 30 sessions on how browser and rich web technologies such as AJAX, DHTML, Mashups, Web 2.0, Enterprise 2.0 technologies, and Rich UI technologies are making money and gaining market-share for some of the leading businesses in the world. The GIDS.Web track at Great Indian Developer Summit takes place 21 and 23 April 2010, at the Indian Institute of Science in Bangalore. As one of the longest running independent developer conferences in India, GIDS.Web at the Great Indian Developer Summit 2010 is uniquely positioned to provide a blend of practical, pragmatic and immediately applicable knowledge and a glimpse of the future of technology. During 21 and 23 April 2010, GIDS.Web offers a multi-track conference, workshops, expo show floor, and networking opportunities. The first keynote at GIDS.Web is led by the leading Java EE and Ajax developer, speaker, and author Marty Hall. The best of India's Java and RIA programmers have learnt the subject from Marty's seminal books Core Servlets and JavaServer Pages (first and second editions), More Servlets and JavaServer Pages, and Core Web Programming (first and second editions) from Prentice Hall and Sun Microsystems Press. Marty's keynote address is a comparison of approaches to building rich Internet applications with Ajax. Marty says Ajax development is difficult, and there are several fundamentally different strategies to building Ajaxified Web applications. The keynote address will survey the three most important of these approaches: using an Ajax-enabled JavaScript library such as jQuery, Prototype, Scriptaculous, Dojo, or Ext/JS; using a Web framework such as JSF 2.0 or Struts 2 that has integrated Ajax support; using the Google Web Toolkit (GWT) to build "pure Java" Ajax applications. The talk will compare and contrast these three approaches, discussing the types of applications that fit best for each option. Over the course of the summit Marty will conduct several more sessions on "Choosing an Ajax/JavaScript Toolkit: A Comparison of the Most Popular JavaScript Libraries", "Pure Java Ajax: An Overview of GWT 2.0", "Integrated Ajax Support in JSF 2.0" and "Ajax Support in the Prototype JavaScript Library". The second keynote by the head of Adobe's Flash initiative in India, Ramesh Srinivasaraghavan, explores the state of art in web application development and identify trends that could transform the way we create and use web applications. The talk explains how the Adobe Flash Platform has fuelled this revolution with an integrated set of technologies for delivering the most compelling applications, content and video to the widest possible audience. The Director of Forum Nokia will explain how cloud computing coupled with mobile applications enable consumers to have access to powerful services and improved user experiences never before thought possible.

• R12.0 Cash Management Consolidated Patch Collection (CPC) And R12.1 Cash Management Recommended Patch Collection (RPC)

  - by user793553

  If you have Oracle E-Business Suite's Cash Management (CE) application installed, you'll want to be sure to install the latest CPC (Consolidated Patch Collection) if you are using a R12.0 version of the apps, or the latest RPC (Recommended Patch Collection) for the R12.1 version of the apps. These collections give you all the fixes currently available for known issues in the specified versions of the application, including all of the latest Root Cause Analysis Fixes (RCAs)! What is an "RPC" (for R12.1 users)? Since the release of 12.1, a number of recommended patches for Oracle Cash Management have been made available as standalone patches to help address important business process issues. Adoption of these patches was highly recommended at the time, but not always implemented, so to further facilitate adoption of these patches, Oracle consolidated them into product-specific Recommended Patch Collections (RPCs) - a collection of recommended patches. They were created by Oracle Development with the following goals in mind: Stability: To address data integrity issues that have been identified by Oracle Development and Oracle Software Support as having the potential to interfere with the normal completion of important business processes (such as, period close, etc.). Root Cause Fixes (RCAs): To make available root cause fixes for known data integrity issues. Compact: To keep the file footprint as small as possible to help facilitate the install process and minimize testing. Granular: To compile the collection of patches based on functional areas, allowing a customer to apply multiple RPCs at once, or in phases (based on individual needs and goals). Where to start ALL R12 Cash Management users (R12.0 and R12.1 users) should start with the following Note on My Oracle Support (MOS): Doc ID 1367845.1: R12: Cash Management Recommended Patch Collections It's a great place for important implementation information about both sets of critical patch collections! For R12.1x users R12.1 users should also take a look at the documents below for even more information about the RPC for the R12.1.x versions of the Cash Management application, and other related available RPCs: Note Number  Title                                                                                                      1489997.1 Master Troubleshooting Guide for CE: Reconciliation & Clearing [VIDEO] 954704.1 EBS: R12.1 Oracle Financials Recommended Patch Collections (RPCs) 1316506.1 R12: Oracle CE: Upgrading from R11i to R12.1: Latest Recommended Patches Patch Wizard Utility While a patch may contain several hundred files, the impact on your system may actually be minimal. Patches contain hard prerequisites that are intended to make a patch work on a very low code baseline. The Patch Wizard Utility will give you a detailed analysis of the patch’s impact on your instance BEFORE it’s applied, so you’ll know exactly what to expect from the application. Please refer to Doc ID 976188.1 for more information on this important utility

• .LazyInitializationException when adding to a list that is held within a entity class using hibernat

  - by molleman

  Right so i am working with hibernate gilead and gwt to persist my data on users and files of a website. my users have a list of file locations. i am using annotations to map my classes to the database. i am getting a org.hibernate.LazyInitializationException when i try to add file locations to the list that is held in the user class. this is a method below that is overridden from a external file upload servlet class that i am using. when the file uploads it calls this method. the user1 is loaded from the database elsewhere. the exception occurs at user1.getFileLocations().add(fileLocation); . i dont understand it really at all.! any help would be great. the stack trace of the error is below public String executeAction(HttpServletRequest request, List<FileItem> sessionFiles) throws UploadActionException { for (FileItem item : sessionFiles) { if (false == item.isFormField()) { try { YFUser user1 = (YFUser)getSession().getAttribute(SESSION_USER);

// this is where the file is written to disk item.write(file); // the FileLocation object is then created FileLocation fileLocation = new FileLocation(); fileLocation.setLocation(fileLocationString); //test System.out.println("file path = "+file.getPath()); user1.getFileLocations().add(fileLocation); //the line above is where the exception occurs } catch (Exception e) { throw new UploadActionException(e.getMessage());

• Throttle connections to web service if load gets too high?

  - by Joseph Turian

  I have a web site that communicates via XMLRPC with an XMLRPC server web service. (The web service is written in Python using xmlrpclib.) I believe that xmlrpclib will block while it is handling one request. So if there are three users with an xmlrpclib request ahead of you, your response takes four times as long. How do I handle it if I receive too many XMLRPC requests and the web service gets bogged down and has slow response time? If I am getting slashdotted, my preferred behavior is that the first users get good response times and everyone else is told to come back later. I think this is superior to giving everyone terrible response times. How do I create this behavior? Is this called load-balancing? I am not actually balancing though, until I have multiple servers.

From remote machine i can check my mails in owa (https://mycompany.dyndns.org/exchange) But i can't set up outlook 2013 to remote connect. I installed server.mycompany.local to remote machine trusted cert container, but i got error message: "There is a problem with the proxy server's security certificate. The name on the security certificate is invalid or does not match the name of the target site. Outlook is unable to connect to the proxy server.
