  • How do I migrate a ManyToOne to a ManyToMany relationship in Hibernate?

    - by spderosso
    I have a instance field of a class X that is mapped using Hibernate as a Many to One relationship. E.g: public class X{ ... @ManyToOne(optional=false) private Y iField; ... } That is correctly working with a particular schema. I know want to change this instance field iField to a List and a Many to Many relationship. public class X{ ... @ManyToMany(optional=false) private List<Y> iField; ... } What steps should I follow? Do I have to change the schema? in which way? In case you need more info let me know. Thanks!

    - by Troy
    I am getting a string from the user and then doing some checking to make sure it is valid, here is the code I have been using; char digit= userInput.charAt(0) - '0'; This had been working fine until I did some work on another method, I went to compile and have been receiving a 'possible loss of precision' error since then. What am I doing wrong?

  • Proper use of HttpRequestInterceptor and CredentialsProvider in doing preemptive authentication with

    - by Preston
    I'm writing an application in Android that consumes some REST services I've created. These web services aren't issuing a standard Apache Basic challenge / response. Instead in the server-side code I'm wanting to interrogate the username and password from the HTTP(S) request and compare it against a database user to make sure they can run that service. I'm using HttpClient to do this and I have the credentials stored on the client after the initial login (at least that's how I see this working). So here is where I'm stuck. Preemptive authenticate under HttpClient requires you to setup an interceptor as a static member. This is the example Apache Components uses. HttpRequestInterceptor preemptiveAuth = new HttpRequestInterceptor() { @Override public void process( final HttpRequest request, final HttpContext context) throws HttpException, IOException { AuthState authState = (AuthState) context.getAttribute(ClientContext.TARGET_AUTH_STATE); CredentialsProvider credsProvider = (CredentialsProvider) context.getAttribute( ClientContext.CREDS_PROVIDER); HttpHost targetHost = (HttpHost) context.getAttribute(ExecutionContext.HTTP_TARGET_HOST); if (authState.getAuthScheme() == null) { AuthScope authScope = new AuthScope(targetHost.getHostName(), targetHost.getPort()); Credentials creds = credsProvider.getCredentials(authScope); if (creds != null) { authState.setAuthScheme(new BasicScheme()); authState.setCredentials(creds); } } } }; So the question would be this. What would the proper use of this be? Would I spin this up as part of the application when the application starts? Pulling the username and password out of memory and then using them to create this CredentialsProvider which is then utilized by the HttpRequestInterceptor? Or is there a way to do this more dynamically?

  • Incremental build with NetBeans and Maven for jetty hot deployment

    - by deamon
    After my unsuccessful attempt to run Tomcat with hot deployment from NetBeans with Maven, I've tried jetty. The jetty-maven-plugin doc gave me an important hint: The plugin will automatically ensure the classes are rebuilt and up-to-date before deployment. If you change the source of a class and your IDE automatically compiles it in the background, the plug-in will pick up the changed class. If I look at $myproject/target/classes/... in the projects directory, I can see that NetBeans doesn't compile and refresh the class file on saving. I need to build the project explicitly to update the file and than jetty picks up the change. (The plug-in param "scanIntervalSeconds" is set to 1.) How can I tell NetBeans to compile on save and update the class file so that jetty can pick up the change?

  • Best way to access database from android

    - by Brandon Delany
    I am working on a Android app and I have a dilemma. I have a list of Objects. I have to update each of these objects with a database. I have 2 methods: Method 1: I can loop through the Objects. For each object I can connect to the server, update it, and then move on to the next Object, and so forth. Method 2: I can store the Objects in a list, send the whole list to the server, update it on the server side, then return a list of updated objects. My questions are: Which method is faster? Which method is easier on the phone's battery? By the way, Method 1 is easier for me to code :). Thank you.

  • How to sett up hibernate to use Glassfish connection pool?

    - by jschoen
    I have set up a connection pool in Glassfish with a jndi resource for it also setup. I am stumped on how to configure hibernate to go get it. I have come across alot of write ups to configure it to use C3P0 connection pool. Well I am lost. I found that I need to set: hibernate.connection.datasource hibernate.jndi.url hibernate.jndi.class hibernate.connection.username hibernate.connection.password Would datasource be the same as the hibernate.connection.datasource set in the connection pool? What would hibernate.jndi.class be? Are hibernate.connection.username and hibernate.connection.password for the connection to the database or to the appserver? I assume this is to the database, but why do I need them since that is all set in the appserver?

  • Oauth callback problem

    - by yogsma
    I am using OAuth with google data api. We have a portal only for authorized users. So when users are logged in and if they are accessing calendar page, they will be asked if they want to sync their calendars with google calendar. If yes, they will be redirected for authentication. Once user has granted access, google appends OAuth_Token to the callback URL. the callback URL was that of the page of calendar in portal. This url has its query string options encrypted. But when the redirection happens , it takes back to login page of url. url is like http://aaa.xyz.com/(encrypted part of query string) and after oauth_token is authorized, this url becomes http://aaa.xyz.com/(encrypted part of query string)&oauth_token. So the user sees the login page after redirection instead of original page. How should I handle this in code.

  • Jetty 7 Continuations: How to *not* redispatch the request?

    - by Don Werve
    I'm using Jetty 7 continuations to implement some asynchronous processing. What I'm trying to do is start off the continuation (via .suspend()), and then hand the continuation off to some other object that will compose the response, which works fine. But Jetty keeps redispatching the response (with isInitial = false) to the servlet, and I don't want or need that, because the response is being dealt with by some other object. So, I'd like to find a way to explicitly not redispatch the request on timeout or expire, because I'm using an event-driven series of callbacks to actually produce the response.

  • Android - Making an activity display different things depending on what is clicked

    - by user3682017
    I have a listview that is populated by an arraylist of classes. public void populateThingsList(){ listExample.add(new Example("Example name", 1, "Example detail 1", "Example detail 2", R.drawable.1_icon, "Example detail 3")); listExample.add(new Example("Example name1", 2, "Example detail 1", "Example detail 2", R.drawable.2_icon, "Example detail 3")); listExample.add(new Example("Example name2", 3, "Example detail 1", "Example detail 2", R.drawable.3_icon, "Example detail 3")); listExample.add(new Example("Example name3", 4, "Example detail 1", "Example detail 2", R.drawable.4_icon, "Example detail 3")); listExample.add(new Example("Example name4", 5, "Example detail 1", "Example detail 2", R.drawable.5_icon, "Example detail 3")); listExample.add(new Example("Example name5", 6, "Example detail 1", "Example detail 2", R.drawable.6_icon, "Example detail 3")); listExample.add(new Example("Example name6", 7, "Example detail 1", "Example detail 2", R.drawable.7_icon, "Example detail 3")); listExample.add(new Example("Example name7", 8, "Example detail 1", "Example detail 2", R.drawable.8_icon, "Example detail 3")); listExample.add(new Example("Example name8", 9, "Example detail 1", "Example detail 2", R.drawable.9_icon, "Example detail 3")); listExample.add(new Example("Example name9", 10, "Example detail 1", "Example detail 2", R.drawable.10_icon, "Example detail 3")); } This is the code for the clicklistener. ListView list = (ListView) findViewById(R.id.exampleListView); list.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Example clickedexample = listExample.get(position); startActivity(new Intent("com.example.app.EXAMPLEACTIVITY")); } } Is there any way I can get the information from clickedExample and set the textViews and imageView in ExampleActivity depending on which one was clicked?

  • Using Session Bean provided data on JSF welcome page

    - by takachgeza
    I use JSF managed beans calling EJB methods that are provide data from database. I want to use some data already on the welcome page of the application. What is the best solution for it? EJBs are injected into JSF managed beans and it looks like the injection is done after executing the constructor. So I am not able to call EJB methods in the constructor. The normal place for EJB call is in the JSF action methods but how to call such a method prior to loding the first page of the application? A possible solution would be to call the EJB method conditionally in a getter that is used on the welcome page, for example: public List getProductList(){ if (this.productList == null) this.productList = myEJB.getProductList(); return this.productList; } Is there any better solution? For example, in some config file?

  • How to generate an ear file from a maven-archetype-webapp artifact?

    - by Mike
    I currently have a project built with maven-archetype-webapp artifact. The default packaging for this project is war. Is it possible for me to insert the maven-ear-plugin in this webapp pom.xml generate an ear file that contains this project war? I tried that, but the war file doesn't get embedded in the generated ear file. It has everything except the war file. I read many Maven related articles, and perhaps I could use maven-archetype-j2ee-simple artifact. However, I'm reluctant to this use for 2 reasons:- This artifact handles ejbs and all the extra features that I don't use. It makes my project looks bloated. Second, it seems like it requires me to install the web module into the repository first before I can create the ear file. Is this the preferred way to create an ear file? How do I create an ear file that contains the war file using maven-ear-plugin from my webapp's pom.xml? If this way is not possible, what's the preferred way? I'm sorry if my questions sound a little novice, I realized I have whole lot more to learn about Maven. Thanks much.

  • How to get error text in controller from BindingResult

    - by Mike
    I have an controller that returns JSON. It takes a form, which validates itself via spring annotations. I can get FieldError list from BindingResult, but they don't contain the text that a JSP would display in the tag. How can I get the error text to send back in JSON? @RequestMapping(method = RequestMethod.POST) public @ResponseBody JSONResponse submit(@Valid AnswerForm answerForm, BindingResult result, Model model, HttpServletRequest request, HttpServletResponse response) { if (result.hasErrors()) { response.setStatus(HttpServletResponse.SC_BAD_REQUEST); JSONResponse r = new JSONResponse(); r.setStatus(JSONResponseStatus.ERROR); //HOW DO I GET ERROR MESSAGES OUT OF BindingResult??? } else { JSONResponse r = new JSONResponse(); r.setStatus(JSONResponseStatus.OK); return r; } } JSONREsponse class is just a POJO public class JSONResponse implements Serializable { private JSONResponseStatus status; private String error; private Map<String,String> errors; private Map<String,Object> data; ...getters and setters... } Calling BindingResult.getAllErrors() returns an array of FieldError objects, but it doesn't have the actual errors.

  • Hierarchical object model with property inheritance and event bubbling?

    - by Winston Fassett
    I'm writing a document-based client application and I need a DOM or WPF-like, but non-visual model that: Is a tree composed of elements Can accept an unlimited number of custom properties that get/set any CLR type, including collections. Can inherit their values from their parent Can inherit their default values from an ancestor Can be derived/calculated from other properties, ancestors, or descendants Support event bubbling / tunneling There will be a core set of properties but other plugins may add their own or even create custom documents Supports full inspection by the owning document in order to persist the tree and attributes in an XML format. I realize that's a tall order but I was really hoping there would be something out there to help me get started. Unfortunately WPF DependencyObjects are too closed, proprietary, and coupled to WPF to be of any use as a document model. My needs also have a strong resemblance to the HTML DOM but I haven't been able to find any clean DOM implementations that could be decoupled from HTML or ported to .NET. My current platform is .NET/C# but if anyone knows of anything that might be useful for inspiration or embedding, regardless of the platform, I'd love to know.

  • How to set JtextArea to keep fixed no of rows?

    - by Hippo
    How can i keep no of rows constant in text area. I need to create a console window for my application. If rows exceeds predefined no of rows first rows must get disposed. As if first written row will be destroyed first when i append anything which exceeds no of rows set. One more thing , i need to keep vertical scroll bar. That means no of rows must not be the whatever rows are visible when text area it opened. For example : - no of visible rows on view port are 30. It should keep 120 rows information, which will can be seen with the help of scroll bar.

  • Draw a JButton to look like a JLabel (or at least without the button edge?)

    - by Electrons_Ahoy
    I've got a JButton that for various reasons I want to act like a button, but look like a JLabel. It doesn't actually have to be a JLabel under the hood, I just don't want the raised button edge to show up. Is there an easy way to turn off the "button look" for JButtons but keep all the button functionality? I could build some kind of composed subclass hyperbutton that delegated to a jlabel for display purposes, but I'm really hoping there's something along the lines of button.lookLikeAButton(false).
