  • Servlet Security question about j_security_check, j_username and j_password

    - by Nitesh Panchal
    Hello, I used jdbcRealm in my web application and it's working fine. I defined all constraints also in my web.xml. Like all pages of url pattern /Admin/* should be accessed by only admin. I have a login form with uses standard j_security_check, j_username and j_password. Now, when i type Admin/home.jsf it rightly redirects me login.jsf and there when i type the password i am redirected to home.jsf. This works alright but problem comes i directly go to login.jsf and then type password and username. This time it again redirects me to login.jsf. Is there any way through which i can specify which page to go when successful login is there? I need to specify different different pages for different roles. For Admin, it is /Admin/home.jsf for general users it is /General/home.jsf because login form is shared between different type of users. Where do i specify all these things? Secondly, i want to have a remember me checkbox at the end of login form. How do i do this? By default, it is submitted to j_security_check servlet and i have no control over its execution. Please help. This doesn't seem so hard but looks like i am missing something.

  • How do you use FastInfoset with JAXWS?

    - by Chris Kessel
    I've got code that looks like it should be correct based on what I can find, but the spewed output doesn't indicate that it's using FastInfoset. My understanding is the Accept should indicate it can accept Fastinfoset and the response would actually use it, meaning it's not text/xml as the response type. Any idea what I'm doing wrong? I've scoured with Google and I'm having a hard time finding much detail on how to use FastInfoset at all. JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean(); factory.getInInterceptors().add(new LoggingInInterceptor()); factory.getOutInterceptors().add(new LoggingOutInterceptor()); factory.setServiceClass( C360Server.class); factory.setAddress("http://localhost:8501/cxfcontroller/cl_v5"); C360Server client = (C360Server)factory.create(); ((BindingProvider)client).getRequestContext().put( "com.sun.xml.ws.client.ContentNegotiation", "optimistic"); C360Request requestTrans = new C360Request(); ... code to fill in the request ... C360Response response = client.findContacts( requestTrans ); The logging doesn't seem to indicate FastInfoset is even attempted though: INFO: Outbound Message --------------------------- ID: 1 Address: http://localhost:8501/cxfcontroller/cl_v5 Encoding: UTF-8 Content-Type: text/xml Headers: {SOAPAction=[""], Authorization=[Basic cWFfc3VwZXI6cWFfc3VwZXI=], Accept=[*/*]} Payload: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><ns1:findContacts>...bunch of xml deleted for brevity...</ns1:findContacts></soap:Body></soap:Envelope> -------------------------------------- May 17, 2010 3:23:45 PM org.apache.cxf.interceptor.LoggingInInterceptor logging INFO: Inbound Message ---------------------------- ID: 1 Response-Code: 200 Encoding: UTF-8 Content-Type: text/xml; charset=utf-8 Headers: {content-type=[text/xml; charset=utf-8], Content-Length=[611], Server=[Jetty(6.1.x)]} Payload: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><ns1:findContactsResponse>...bunch of xml spew deleted for brevity...</ns1:findContactsResponse></soap:Body></soap:Envelope> -------------------------------------- Any ideas what I'm doing wrong? Even if the server wasn't supporting FastInfoset, I still should see the attempted negotiation in the request, right?

  • Which use cases make temporary JMS queues a better choice than persistent queues?

    - by Stephen Harmon
    When you are designing a JMS application, which use cases make you pick temporary queues over persistent queues? We use temporary queues for response messages. We're having some issues maintaining connections to the temp queues, though, so I am testing persistent response queues, instead. One clear disadvantage of persistent queues is that your application has to "know" about them beforehand. If that's not a big deal, though, are there use cases where temp queues are the obvious choice?

  • How can I serve static content with Glassfish embedded?

    - by Andy Fiedler
    I'm trying to setup Glassfish embedded with a WAR project that implements a REST API and then some static Javascript content that calls it. I got the WAR to deploy and the REST API is available with a context root of "/Users". How can I use Glassfish to serve static content with a context root of "/". So for example, if the user requests http://myserver.com/Users/some-REST-call it routes to the WAR application and http://myserver.com/somefile.js serves a static file from some directory? Here's my Main class file so far: public class Main{ public static void main(String[] args) throws Exception { String port = System.getenv("PORT"); port = port != null ? port : "8080"; GlassFishProperties gfProps = new GlassFishProperties(); gfProps.setPort("http-listener", Integer.parseInt(port)); GlassFish glassfish = GlassFishRuntime.bootstrap().newGlassFish(gfProps); glassfish.start(); Deployer deployer = glassfish.getDeployer(); deployer.deploy(new File("target/Users-Rest.war")); } } Thanks a ton for your help!

  • Long running method causing race condition

    - by keeleyt83
    Hi, I'm relatively new with hibernate so please be gentle. I'm having an issue with a long running method (~2 min long) and changing the value of a status field on an object stored in the DB. The pseudo-code below should help explain my issue. public foo(thing) { if (thing.getStatus() == "ready") { thing.setStatus("finished"); doSomethingAndTakeALongTime(); } else { // Thing already has a status of finished. Send the user back a message. } } The pseudo-code shouldn't take much explanation. I want doSomethingAndTakeALongTime() to run, but only if it has a status of "ready". My issue arises whenever it takes 2 minutes for doSomethingAndTakeALongTime() to finish and the change to thing's status field doesn't get persisted to the database until it leaves foo(). So another user can put in a request during those 2 minutes and the if statement will evaluate to true. I've already tried updating the field and flushing the session manually, but it didn't seem to work. I'm not sure what to do from here and would appreciate any help. PS: My hibernate session is managed by spring.

  • Using enums or a set of classes when I know I have a finite set of different options?

    - by devoured elysium
    Let's say I have defined the following class: public abstract class Event { public DateTime Time { get; protected set; } protected Event(DateTime time) { Time = time; } } What would you prefer between this: public class AsleepEvent : Event { public AsleepEvent(DateTime time) : base(time) { } } public class AwakeEvent : Event { public AwakeEvent(DateTime time) : base(time) { } } and this: public enum StateEventType { NowAwake, NowAsleep } public class StateEvent : Event { protected StateEventType stateType; public MealEvent(DateTime time, StateEventType stateType) : base(time) { stateType = stateType; } } and why? I am generally more inclined to the first option, but I can't explain why. Is it totally the same or are any advantages in using one instead of the other? Maybe with the first method its easier to add more "states", altough in this case I am 100% sure I will only want two states: now awake, and now asleep (they signal the moments when one awakes and one falls asleep).

  • Grails query not using GORM

    - by Tihom
    What is the best way to query for something without using GORM in grails? I have query that doesn't seem to fit in the GORM model, the query has a subquery and a computed field. I posted on stackoverflow already with no response so I decided to take a different approach. I want to query for something not using GORM within a grails application. Is there an easy way to get the connection and go through the result set?

  • Performance implications of finalizers on JVM

    - by Alexey Romanov
    According to this post, in .Net, Finalizers are actually even worse than that. Besides that they run late (which is indeed a serious problem for many kinds of resources), they are also less powerful because they can only perform a subset of the operations allowed in a destructor (e.g., a finalizer cannot reliably use other objects, whereas a destructor can), and even when writing in that subset finalizers are extremely difficult to write correctly. And collecting finalizable objects is expensive: Each finalizable object, and the potentially huge graph of objects reachable from it, is promoted to the next GC generation, which makes it more expensive to collect by some large multiple. Does this also apply to JVMs in general and to HotSpot in particular?

  • http_access.log on WebSphere 6.1.0.29

    - by DavidG
    I am running WebSphere 6.1.0.29 and I need to track the requests being made to an Enterprise Application. Previously I did this by routing the requests through a proxy server, but I need to repeat the exercise and I figure there must be a simpler way. Does anyone know how to enable HTTP access logging? I have been through the console an thought I had enabled http_access.log and http_error.log via: Application servers server1 HTTP error and NCSA access logging (where 'server1' is the application server) I've enabled the service at startup, and ticked the boxes to enable access logging and error logging - however... nothing has happened. I have restarted the server, restarted the Enterprise apps and even did a "find . -name" for the log files - but they don't seem to be anywhere on the system. I saw on a JavaRanch thread someone suggested writing a custom filter for requests in an application, but this seems like wild overkill - plus I am doing the logs to test a pre-built binary, so I don't want to mess with the code. Anyone have any ideas/suggestions? Help! :-)

  • How to specify schema location in an xsd file?

    - by Manoj
    I have an xsd file Foo.xsd. I tried following ways to refer it in a WSDL file but it doesnt work. 1) placed the xsd file in local file system and imported it as <xsd:import namespace="http://ws.test.com/" schemaLocation="file:///D:/wsdl/Foo.xsd"></xsd:import> 2) Placed the xsd file in web root folder and imported as <xsd:import namespace="http://ws.test.com/" schemaLocation="http://localhost:8080/Xfire/Foo.xsd"></xsd:import> When I run the client I get null for the fields of response object. But this works when I embed the type definition inside the WSDL itself. How do we specify the path to external xsds? I am using xFire 1.2.6 for generating webservices. Client is generated using xFire WSGen ant task.

  • How to sort an array or ArrayList<Point> ASC first by x and then by y?

    - by newba
    Hi everyone, I just want to use Collections.sort or Arrays.sort to sort a list of points (class Point) by x first and then by y. I have a class Ponto that implements Comparable like this: public int compareTo(Ponto obj) { Ponto tmp = obj; if (this.x < tmp.x) { return -1; } else if (this.x > tmp.x) { return 1; } return 0; } but now I want to sort by y too after x. How can I do that by modifying the above code? Or is that a better and "clean" way to do this? I also use to pass this code to C++, in which I've created a structure called Point with a equivalent comparable method.

  • JSF: attach rich:toggleControl to radio buttons or select items.

    - by arw
    Has anyone had any success attaching a rich:toggleControl component to a radio button component (h:selectOneRadio) or alternatively any of its children select items (in this case s:enumItem). Basic code example: <h:selectOneRadio value="#{backingValue}"> <s:enumItem enumValue="VAL_1" itemLabel="Value One" /> <s:enumItem enumValue="VAL_2" itemLabel="Value Two" /> <s:convertEnum /> </h:selectOneRadio> The ideal thing would be to attach the toggle control to the enumItems so I could have it switch to a particular state. However at this point I'd be happy if the toggle control can just be attached to the selectOneRadio. I've tried the toggle control as a child of the selectOneRadio and enumItems; neither works. I've also tried wrapping the toggleControl around the selectOneRadio, the toggle control works in this case but the radio buttons don't :(

  • Creating custom Android project templates in Eclipse?

    - by Rich
    Every app I make starts out with a number of common base classes, interfaces, utility classes and a basic package structure that has been working for me. Is there a way for me to set up a project template in Eclipse that will give me all of the basic Android project stuff PLUS a bunch of custom packages, classes and interfaces? I guess I could just put all of this stuff into one or more libraries as opposed to creating a whole project template, so if you have a preferred approach or information/links/etc on how to do any of the above, please share (I'm relatively inexperienced with Eclipse, so the more detail the better). Thanks.

  • Use ObjectOutputStream and FileOutputStream with FileWriter

    - by wishi
    Hi! Is there any way to use ObjectOutputStream like this: <tag>output of the ObjectOutputStream</tag> If I try: FileOutputStream fos = new FileOutputStream(filename); ObjectOutputStream oos = new ObjectOutputStream(fos); FileWriter fw = new FileWriter(fos); And for example: fw.write("<tag>"); oos.write(cool_object); fw.wrote("</tag>"); I don't get that result. It seems the ObjectOutputStream overwrites the file completly each and every time.

  • h:graphicimage not working in c:foreach

    - by Muneeswaran Balasubramanian
    I have used c:forEach loop for display the list of images using h:graphicImage. But I can't display the images. I have the h:commandLink also in my page. The image have to be displayed at the time of form inititalization. But its not working. But after click the h:commandlink, the images are displayed properly. Before that it shows the image not found text (alt message). I have used h:graphicImage tag like below <c:forEach items="#{Sample.imageList}" var="images" varstatus="imageStatus"> <h:graphicimage id="image" url="#{images}" alt="Image Not Found"/> </c:forEach> What I do wrong in that and how can I achieve that?

  • Primary reasons why programming language runtimes use stacks?

    - by manuel aldana
    Many programming language runtime environments use stacks as their primary storage structure (e.g. see JVM bytecode to runtime example). Quickly recalling I see following advantages: Simple structure (pop/push), trivial to implement Most processors are anyway optimized for stack operations, so it is very fast Less problems with memory fragmentation, it is always about moving memory-pointer up and down for allocation and freeing complete blocks of memory by resetting the pointer to the last entry offset. Is the list complete or did I miss something? Are there programming language runtime environments which are not using stacks for storage at all?

  • Passing session between jsf backing bean and model

    - by Rachel
    Background : I am having backing bean which has upload method that listen when file is uploaded. Now I pass this file to parser and in parser am doing validation check for row present in csv file. If validation fails, I have to log information and saving in logging table in database. My end goal : Is to get session information in logging bean so that I can get initialContext and make call to ejb to save data to database. What is happening : In my upload backing bean, am getting session but when i call parser, I do not pass session information as I do not want parser to be dependent on session as I want to unit test parser individually. So in my parser, I do not have session information, from parser am making call to logging bean(just a bean with some ejb methods) but in this logging bean, i need session because i need to get initial context. Question Is there a way in JSF, that I can get the session in my logging bean that I have in my upload backing bean? I tried doing: FacesContext ctx = FacesContext.getCurrentInstance(); HttpSession session = (HttpSession) ctx.getExternalContext().getSession(false); but session value was null, more generic question would be : How can I get session information in model bean or other beans that are referenced from backing beans in which we have session? Do we have generic method in jsf using which we can access session information throughout JSF Application?
