  • Unable to connect on socket across different networks.

    - by maleki
    I am having trouble connecting my online application to others across another network. I am able to give them the hostAddress to connect when we are on the same network but when we are doing it across the internet the generated host address doesn't allow a connection, nor does using the ip address gotten from online sites such as whatismyip.com My biggest issue isn't debugging this code, because it works over intra-network but The server doesn't see attempts when we try to move to different networks. Also, the test ip I am using is 2222. InetAddress addr = InetAddress.getLocalHost(); String hostname = addr.getHostName(); System.out.println("Hostname: " + hostname); System.out.println("IP: " + addr.getHostAddress()); I display the host to the server when it is starting if (isClient) { System.out.println("Client Starting.."); clientSocket = new Socket(host, port_number); } else { System.out.println("Server Starting.."); echoServer = new ServerSocket(port_number); clientSocket = echoServer.accept(); System.out.println("Warning, Incoming Game.."); }

  • What's in an Eclipse .classpath/.project file?

    - by totalEclipse
    We recently had an issue with an Eclipse project for one of our team members. Tomcat was not deploying JARs of the application. We eventually noticed the .classpath Eclipse file was not the same as for the team members where the project was OK. We replaced the .classpath file with one from a project that was OK and the Tomcat deploy was complete. Just out of curiosity and to know at what to look in the future if something is wrong, what is inside the .classpath and .project files. What can I add in there, what does it all mean?

  • DataSource for Tomcat web app, Spring and Hibernate

    - by EugeneP
    Web app runs on Tomcat. Datasource is configured with Spring configuration, and is used by Hibernate. If we cannot use JNDI, what would you suggest to use as a DataSource? org.springframework.jdbc.datasource.DriverManagerDataSource will be ok? It's not very good, but sincerely speaking, it can be used on production server, right? Just a bit of headache with too frequent connection reopening. Also, we can use BasicDataSource from Apache. It's much better of course, but here's the question. IF WE DON'T USE JNDI, THEN: If every instance of an app will create its own copy of a DataSource, and every DataSource can have 5 open connections, what do we get? Num_of_running_apps * Num_of_max_active_connections = max active open connection on a DB for this user? Second question: from the perspective of Hibernate, is there any difference about what datasource implementation is used? Will it work with no matter what datasource perfectly and in a stable way?

  • Just curious, in NetBeans IDE 6.1 how can i get icons for my custom GUI components in the GUI editor

    - by Coder
    This is by no means really important, i was just wondering if the community knows how to put icons for my custom GUI components that show up in the NetBeans GUI designer. What i did was make several Swing components and then i use the menu options to add them to the GUI pallete, but they show up with "?" icons. It would be nice if they showed up with icons similar to swing components such as JButtons, especially for components which are subclassed for Swing components. Thanks!

  • Using AWT components inside a JInnerFrame (for JDesktopPane)

    - by Jack
    Hello, is there a way to hack bugs related to adding an AWT component (in my case a PApplet, so a processing language sketch) inside a JInternalFrame? It works but not as intended, since it flickers and dragging the frame causes repaint issues.. reading around it seems that, althrough it's possible to mix heavyweight (AWT) and lightweight (Swing) components some problems seem to be unavoidable.. is it true? Thanks!

  • Problem locating file in a classpath

    - by Gandalf StormCrow
    I'm trying to read in file content, ex : public void myMethod(){ FileInputStream fstream = new FileInputStream(fileLocation); // Get the object of DataInputStream DataInputStream in = new DataInputStream(fstream); BufferedReader br = new BufferedReader(new InputStreamReader(in)); String strLine; while ((strLine = br.readLine()) != null) { .... .... ..... end while end method And I have at the begining of the class body private String fileLocation; and at the end of a class I have a getter and setter for it. Now I'm trying inject this file location from spring inside bean from this class and I specify the init-method of this class. But I get error cannot find the specified file as if its not on a classpath but it is inside war file? I'm building the project with maven and I put file in src/main/resources This is the error I get when trying to read file : Error: src\main\resources\ids.txt (The system cannot find the path specified) That is when I tried this : FileInputStream fstream = new FileInputStream("src\\main\\resources\\ids.txt"); how to reference the properly from the classpath? EDIT When I edit my code according to @BalusC solution , here is how it looks but I still get null error : ClassLoader classLoader = Thread.currentThread().getContextClassLoader(); InputStream input = classLoader.getResourceAsStream("src/main/resources/ids.txt"); // Get the object of DataInputStream BufferedReader br = new BufferedReader(new InputStreamReader(input)); String strLine; while ((strLine = br.readLine()) != null) { .... .... ..... end while end method

  • eclEmma - full code coverage on class header?

    - by Fork
    Hi, I have a class that starts with: public class GeneralID implements WritableComparable<GeneralID>{ ... } And another that is: public class LineValuesMapper<KI, VI, KO, VO> extends Mapper<LongWritable, Text, Text, IntWritable>{ ... } All methods in these classes are covered. But not their header. The header of both classes gets painted as yellow with EclEmma. Is there anything I can do to fully cover the class header?

  • Memory dump much smaller than available memory

    - by Daniel
    I have a Tomcat Application Server that is configured to create a memory dump on OOM, and it is started with -Xmx1024M, so a Gigabyte should be available to him. Now I found one such dump and it contains only 260MB of unretained memory. How is it possible that the dump is so much smaller than the size he should have available?

  • Is there a way to change the map data for the Android Google Map API?

    - by Mannaz
    I need to use a different datasource inside a map in Android than the google provided data. Is there a way to change the datasource to a tile based service (openstreetmap.org for example)? Or are there other Android map APIs which are OpenSource and can be adapted (except Ericcson Mobile Maps - this doesn't work for me because of the licence)? It doesent have to have a server side part - a rich function library would be enough.

  • Spring Weblfow 2 - Double Submit

    - by John W.
    Hello All, I am investigating a possible issue with double submits and I am looking at the possibilty of a double submit from a webflow execution. I have read many times that webflow will handle double submits, there are plenty references here. However I then came across I a forum response on the spring source forums contradicting what I read saying, SWF synchronizes on the conversation. Only one request will be processed at a time per conversation. Take note that if you're using snapshots, then it's possible repeatedly clicking on the submit button will generate a second request. I would recommend setting history to invalidate or discard in the transition from your view-state. We do have snapshots enabled but the book notes that using snapshots actually allows to solve the double submits. Does anyone have any insight on this? Thanks.

  • The "Why" behind PMD's rules.

    - by James Kingsbery
    Is there a good resource which describes the "why" behind PMD rule sets? PMD's site has the "what" - what each rule does - but it doesn't describe why PMD has that rule and why ignoring that rule can get you in trouble in the real world. In particular, I'm interested in knowing why PMD has the AvoidInstantiatingObjectsInLoops and OnlyOneReturn rules (the first seems necessary if you need to create a new object corresponding to each object in a collection, the second seems like it is a necessity in many cases that return a value based on some criteria). Just to be clear, I know that I can disable these and how to do that, I'm just wondering why they are there in the first place. Sorry if there's something obvious I missed out there, but I did a Google search and SO search before posting this.

  • GWT: Change padding of tree rows?

    - by Epaga
    A GWT tree looks roughly like this: <div class="gwt-Tree"> <div style="padding-top: 3px; padding-right: 3px; padding-bottom: 3px; margin-left: 0px; padding-left: 23px;"> <div style="display:inline;" class="gwt-TreeItem"> <table> ... </table> </div> </div> <div ...> </div> ... </div> My question is: how should I change the padding of the individual tree rows? I suppose I could do something along the lines of setting CSS rules for .gwt-Tree > div but that seems hacky. Is there a more elegant way?

  • How to avoid serializing zero values with Simple Xml

    - by Bram Vandenbussche
    I'm trying to serialise an object using simple xml (http://simple.sourceforge.net/). The object setup is pretty simple: @Root(name = "order_history") public class OrderHistory { @Element(name = "id", required = false) public int ID; @Element(name = "id_order_state") public int StateID; @Element(name = "id_order") public int OrderID; } The problem is when I create a new instance of this class without an ID: OrderHistory newhistory = new OrderHistory(); newhistory.OrderID = _orderid; newhistory.StateID = _stateid; and I serialize it via simple xml: StringWriter xml = new StringWriter(); Serializer serializer = new Persister(); serializer.write(newhistory, xml); it still reads 0 in the resulting xml: <?xml version='1.0' encoding='UTF-8'?> <order_history> <id>0</id> <id_order>2</id_order> <id_order_state>8</id_order_state> </order_history> I'm guessing the reason for this is that the ID property is not null, since integers can't be null. But I really need to get rid of this node, and I'd rather not remove it manually. Any clues anyone?

  • Persistence with Vaadin

    - by palto
    Hi I'm trying to learn vaadin. I'm really confused how to do any kind of application development with persistence because if I have a reference to my service layer objects, they get stored in session and I really don't want that. Persistence stuff just isn't serializable. My case is that I have an already made application that uses Spring and I'm creating a new UI for it with Vaadin. I can inject the spring stuff to my Vaadin application but that gets stored in the session. Any tips? By the way how do you post in the Vaadin forums? I can't find a post button or way to register :)

  • Iterating over a HashMap with JSTL, always getting last Object

    - by hkansal
    Hello, I have a Map, which I tried to iterate over with JSTL. Somehow I could not accomplish even this basic task. I also referred the questions here and here, but that is what I am already doing, still no success. What I tried to do was: <c:forEach items="${myMap}" var="myEntry"> ${myEntry.key} + ${myEntry.value} </c:forEach> But I always get the last object. Maybe I am missing something trivial, please advise. Thank You

  • "org.json.JSONArray implements Serializable": What's the best option to achieve this?

    - by Daxon
    I am using Grails Webflow, what ever object I pass to a view, it must be Serialized. My domain models "implement Serializable", so they work. The problem is when I get a response from a WebService. It is of the org.json.JSONArray class. I just want to pass the whole Array over to the view yet it doesn't implement Serializable, so it fails, Any thoughts on how I can pass this, or my best option? Can I just edit the source of the org.json library and make every class "imp Serializable"? Or process the result into Domain objects that do "imp Serializable"

  • Android OutOfMemoryError - Loading JSON File

    - by jeremynealbrown
    The app I am working on needs to read a JSON file that may be anywhere from 1.5 to 3 MB in size. It seems to have no problem opening the file and converting the data to a string, but when it attempts to convert the string to a JSONArray, OutOfMemoryErrors are thrown. The exceptions look something like this: E/dalvikvm-heap( 5307): Out of memory on a 280-byte allocation. W/dalvikvm( 5307): Exception thrown (Ljava/lang/OutOfMemoryError;) while throwing internal exception (Ljava/lang/OutOfMemoryError;) One strange thing about this is that the crash only occurs every 2nd or 3rd time the app is run, leaving me to believe that the memory consumed by the app is not being garbage collected each time the app closes. Any insight into how I might get around this issue would be greatly appreciated. I am open to the idea of loading the file in chunks, but I'm not quite sure what the best approach is for such a task. Thank you

  • What Does OSGi Solve?

    - by Pablo Fernandez
    I've read on wikipedia and other sites about OSGi, but I don't really see the big picture. It says that it's a component based platform, and that you can reload modules at runtime. Also the "practical example" given everywhere is the Eclipse Plugin Framework. My questions are: 1) What is the CLEAR and SIMPLE definition of OSGi? 2) What COMMON PROBLEMS does it solve? By "common problems" I mean problems we face everyday, like "what can OSGi do for making our jobs more efficient/fun/simple" Thanks.
