• Maven: Multiple class with the same path implemented in different jar

  - by Phuong Nguyen de ManCity fan

  I'm running into trouble with having multiple class with the same path (i.e. same name, same package!!!). For some reason, gwt-dev comes with its own version of org.apache.xerces.jaxp.DocumentBuilderFactoryImpl and javax.xml.parsers.DocumentBuilderFactory. At the same time, spring also depends on these classes but from different jar. I don't know what should be, but look like xalan & xml-api are the two dependencies that spring depends on (these dependency are optional) Funny thing is that eclipse can run the same code (it's a unit test) without problem, but surefire cannot. So I guess the problem is due to the way each runner consider the priority of each jar. Now come to the question: How can I setup my POM so that I can sure that when ever any code running inside my app, then class from a jar will be selected over class from other jar? Thanks.

• XmlSerializer.Deserialize method appends timezone to a time and datetime field

  - by G33kKahuna

  Have a small script in Microsoft.NET 2.0 that deserializes a XML back to a typed object, connects dyanimcally to a web service using ServiceDescription and binds the deserialized typed object to the WebMethod inbound. The XML prior to serialization looks like below <completion_time>12:19:38</completion_time> on the wire when communicating to the web service looks like below <completion_time>12:19:38.0000000-04:00</completion_time> with the timezone appended to the end. This is causing the time to be read differently when communicating to a web service at a different timezone. is there anyway to let XmlSerializer skip the timezone? Or any other known workarounds?

• JSF 2.0 Problem (faces-config)

  - by Sarang

  Hello everybody, We have faces-config.xml in JSF 1.0 where we entry about managed-beans, dependencies & navigations etc. I was developing a sample project using JSF 2.0. But, as I don't know annotation, I need to include face-config.xml externally. Please, provide the solution for it, as in JSF 2.0 we don't need to include it. What is reason behind it ? How do we set a bean as managed-bean. What is annotation ? How is it used ? Thanking you.

• Fixing IP Renewal After Laptop Suspend

  - by Cerin

  I have a laptop running Ubuntu 10.04, and I've noticed that with some wifi networks, but not all, I'm unable to reconnect after coming out of suspension. I've tried both Network Manager and Wicd management daemons, and both get through validation, but get hung up on "Acquiring IP address...". The only solution I've found is to reboot the machine, after which it acquires an IP address very quickly. What's the underlying issue here? What would be a more efficient way to resolve the problem? EDIT: I've noticed that if I open Wicd and manually press "Connect", it fails to acquire an IP. However, if I do nothing and let it automatically try and connect, it acquires an IP and connects just fine...

• Async call Objective C iphone

  - by Sam

  Hi guys, I'm trying to get data from a website- xml. Everything works fine. But the UIButton remains pressed until the xml data is returned and thus if theres a problem with the internet service, it cant be corrected and the app is virtually unusable. here are the calls: { AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate]; if(!appDelegate.XMLdataArray.count > 0){ [UIApplication sharedApplication].networkActivityIndicatorVisible = YES; [appDelegate GetApps]; //function that retrieves data from Website and puts into the array - XMLdataArray. } XMLViewController *controller = [[XMLViewController alloc] initWithNibName:@"MedGearsApps" bundle:nil]; [self.navigationController pushViewController:controller animated:YES]; [controller release]; } It works fine, but how can I make the view buttons functional with getting stuck. In other words, I just want the UIButton and other UIButtons to be functional whiles the thing works in the background. I heard about performSelectorInMainThread but i cant put it to practice correctly any help is appreciated :)

• Passing a 'var' into another method

  - by Danny

  Hi, I am probably totally missing the point here but.... How can I pass a 'var' into another method? (I am using linq to load XML into an Enumerable list of objects). I have differernt object types (with different fields), but the final step of my process is the same regardless of which object is being used. XNamespace xmlns = ScehmaName; var result = from e in XElement.Load(XMLDocumentLocation).Elements(xmlns + ElementName) select new Object1 { Field1 = (string)e.Element(xmlns + "field1"), Field2 = (string)e.Element(xmlns + "field2") }; var result2 = Enumerable.Distinct(result); This code will vary for the different type of XML files that will be processed. But I then want to iterate though the code to check for various issues: foreach (var w in result2) { if (w.CheckIT()) { //do something } } What I would love is the final step to be in a method in the base class, and I can pass the 'var' varible into it from each child class.

• Android: Send arbitrary objects within Activities?

  - by Sebastian

  I have read some question here but I didn't find a solution. I have read about Parcelable, Intents, and sharing specific data within Activities from the android dev docs (both dev guide and reference). Here's the scenario: I have one ListActivity that fills in an object parsing an xml file, it shows a list of values, and when clicked I want to return the object that represents the item clicked to the activity that has called it, for then, call another activity with this object. I read on how to implement Parcelable but seems not being the way. Implementing Parcelable receives a Parcel for the constructor and then reads the values from it (or at least that was what I understood). This makes no sense for me and I can't see how to implement basing on that issue. I build the object parsing the xml file, not having a Parcel. I appreciate some clarifications on this, regards.

• Changing the style attribute of a button according to its state

  - by LambergaR

  I know you can change buttons background by creating a simple XML file, like this: <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android" > <item android:state_window_focused="false" android:state_enabled="true" android:drawable="@drawable/button_normal" /> <!-- ... --> </selection> I was wondering if it is possible to use a similar approach to change the style attribute of an element using the same (or similar) technique. Or, if that is not possible, how can the style attribute be changed during runtime (there is no such thing as button.setStyle(R.style.button)).

• R.java file not updating with UI element's id

  - by Mohit Deshpande

  I added some UI elements to the main.xml file in the res\layout folder and when I try to access them through the call, R.layout.my_uielement, the UI element that I created is not there. Even when I add a new xml file with UI elements, it still doesn't show up in the R.layout class. I have made checked the ids on them and they have the correct format (I think): android:id="@+id/my_button". What could be the problem? Do I need to compile the code first?

• Handle all authentication logic in database or code?

  - by Snuffleupagus

  We're starting a new(ish) project at work that has been handed off to me. A lot of the database sided stuff has been fleshed out, including some stored procedures. One of the stored procedures, for example, handles creation of a new user. All of the data is validated in the stored procedure (for example, password must be at least 8 characters long, must contain numbers, etc) and other things, such as hashing the password, is done in the database as well. Is it normal/right for everything to be handled in the stored procedure instead of the application itself? It's nice that any application can use the stored procedure and have the same validation, but the application should have a standard framework/API function that solves the same problem. I also feel like it takes away the data from the application and is going to be harder to maintain/add new features to.

• Alignment of View Elements within a LinearLayout

  - by Adam

  I hate to ask this question; for some reason I can't figure it out on my own. I have a vertical LinearLayout that contains a custom View that I've defined in my app and and a TextView. I'd like my custom View to be aligned on the top of the screen and the TextView to be aligned at the bottom of the screen. Unfortunately, no matter what changes I make to the attributes of the XML file, my custom View always seems to be centered vertically when I run the emulator. The xml is like the following: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="top"> <CustomView android:id="@+id/customID" android:layout_width="wrap_content" android:layout_height="wrap_content" tileSize="24" android:focusableInTouchMode="true" android:layout_gravity="top"/> <TextView android:id="@+id/text" android:text="@string/droidtactoe_layout_text" android:visibility="visible" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_horizontal" android:textSize="24sp" android:textColor="#00000000" android:layout_gravity="bottom"/> </LinearLayout>

• Why does Java force user-agent through simple Socket IO?

  - by Zombies

  I am using nothing but raw Socket IO. There isn't one HttpURLConnection nor any http client libs in my project. When I run it through wireshark I see somethign very revealing: GET / HTTP/1.1 User-Agent: Java/1.6.0_15 Host: www.google.com Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2 Connection: keep-alive Here is the crazy part, I never put ANY of that in my original request.

How do I redirect to my gwt project entry index.html ? Thanks.

• XSLT: How to remove the self-closed elment

  - by Daoming Yang

  I have a large xml file which contents a lot of self-closed tags. How could remove all them by using XSLT. eg. <?xml version="1.0" encoding="utf-8" ?> <Persons> <Person> <Name>user1</Name> <Tel /> <Mobile>123</Mobile> </Person> <Person> <Name>user2</Name> <Tel>456</Tel> <Mobile /> </Person> <Person> <Name /> <Tel>123</Tel> <Mobile /> </Person> <Person> <Name>user4</Name> <Tel /> <Mobile /> </Person> </Persons> I'm expecting the result: <?xml version="1.0" encoding="utf-8" ?> <Persons> <Person> <Name>user1</Name> <Mobile>123</Mobile> </Person> <Person> <Name>user2</Name> <Tel>456</Tel> </Person> <Person> <Tel>123</Tel> </Person> <Person> <Name>user4</Name> </Person> </Persons> Note: there are thousands of different elements, how can I programmatically remove all the self-closed tags. Another question is how to remove the empty element such as <name></name> as well. Can anyone help me on this? Many thanks.

• SBT equivalent of Ant target

  - by adelbertc

  What is the SBT equivalent (if any) of Ant targets? For example, a snippet in a build.xml file for Ant would be: <target name="runClient" description="run client"> <java classname="client.Client" fork="true"> <jvmarg value="-Djava.rmi.server.codebase=${client_web_codebase}"/> <jvmarg value="-Djava.security.policy=policy"/> <arg value="localhost"/> <classpath> <pathelement location="dist/client.jar"/> </classpath> </java> </target> And then I would do something like ant runClient to launch the application "client.Client" with the jvmargs specified in the XML.. is there an SBT equivalent, or a way for SBT to hook into Ant to do this?

• Using 'Copy as cURL' from Chrome in windows command line

  - by user2029890

  So, Google Chrome as this great 'copy as cURL' option under 'Network' of the Chrome DevTools. Works great in command lines for linux but not in windows. Apparently it has something to do with the single quotes as the error I get is protocol 'http not supported In other words its reading that single quote. Is there a simple way to make this formatable for windows? I tried replacing all the single quotes with double quotes but then nothing happens at all. The command is: curl 'http://www.test.com/login/' -H 'Cookie: PHPSESSID=7dvb25maaaaaa9d7bbbbbc3f6' -H 'Origin: http://www.test.com' -H 'Accept-Encoding: gzip,deflate,sdch' -H 'Host: www.test.com' -H 'Accept-Language: en-US,en;q=0.8' -H 'User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.95 Safari/537.36' -H 'Content-Type: application/x-www-form-urlencoded' -H 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8' -H 'Cache-Control: max-age=0' -H 'Referer: http://www.test.com/login/' -H 'Connection: keep-alive' --data 'loc=&login=user%40test.com&password=password&submit1=Sign+In' --compressed Thank you

• Saving contents of ApplicationState in ASP.Net (MVC)

  - by Saqib

  I have an internal app used to edit XML files on disk. The XML files are loaded into an object model which is stored in ApplicationState. I need to save this data. The one option is to do this every time the user changes some data. However, this seems a bit inefficient - writing the data out to disk each time a change is made. Instead, is it possible to be notified whenever the user closes their browser, plus just before the web server exits? Thus, the data would be saved each time a session ends, plus when the computer shuts down, etc. I thought that Application_End(), Application_Error() and Session_End() in Global.asax would provide this, but these methods don't seem to be called.

• clarification on the concept of "web service"

  - by udit

  Im a little confused on the varying definitions and implementations of web services available as implementations. Need some clarification please. Ones I have used till now: If a vendor gives me a specific format of XML that I can send populated with data to request and I make a simple HTTP POST over the internet passing in the XML String as the payload, is this a web service call ? If so, is there a specific name to it, this kind of web service ? Because obviously, it does not use anything like Axis, WSDL or SOAP to establish this connection. A variant of this is If the vendor gives me an XSD, I use JAXB to make a java class out of it and pass in the serialized version of the object, which eventually works out to be the same as option 1. RESTful web service: Vendor gives me a URL like http://restfulservice/products and I can make HTTP Requests to the URL and depending on what HTTP verb I use, the appropropriate action is called and the response sent over the wire. Ones I have only read about\ have a vague idea about SOAP. How does this work?.. Ive read the W3Schools tutorial and I undertsand that there is a very specific form of XML that is standardized according to W3C standards that we use to pass the same kind of messages as we did in option 1. But how does this work in real life? Vendor sends me what? Do I generate classes? Do I serialize some objects and http post them over to an address? Or do the generated objects themselves have connection methods that will do them for me? What about WSDL? When does a vendor send me WSDL and what do I do with it ? I guess I can generate classes from it. If yes, then what do I do with the generated classes ? When do I need that axis jar to generate classes from something that the vendor sends ? As you can see, I have some clear and other mostly vague ideas about the different kinds of web services available. would help if someone ould clarify and\or point to more real-world resources. I've looked a little bit into Java Web Services on the internet and the numerous four letter acronyms that get thrown at me make me dizzy. Thanks

• MVC 2 in 2 Minutes!

  - by Steve Michelotti

  In a couple of recent Code Camps, I’ve given my presentation: Top 10 Ways MVC 2 Will Boost Your Productivity. In the presentation, I cover all major new features introduced in MVC 2 with a focus on productivity enhancements. To drive the point home, I conclude with a final demo where I build a couple of screens from scratch highlighting many (but not all) of the features previously covered in the talk. A couple of weeks ago, I was asked to make it available online so here it is. In 2 minutes the demo builds a couple screens from scratch that provide a goal setting tracker for a user. MVC 2 features included in the video are: Template Helpers / Editor Templates Server-side/Client-side Validation Model Metadata for View Model HTML Encoding Syntax Dependency Injection Abstract Controllers Custom T4 Templates Custom MVC Visual Studio 2010 Code Snippets The complete code samples and slide deck can be downloaded here: Top 10 Ways MVC 2 Will Boost Your Productivity.
