  • Suggestion To Stackoverflow [closed]

    - by Eddy Freeman
    Hello Stackoverflow Team, This is just a suggestion to you. In the first place i must say that you guys are doing a great job. I suggest that you build into the forum system a mail notifier(to notify users whenever there is a move/deletion of a post with the reason of the move/deletion) so that whenever you move or removed someone's post then he can be notified about the move, so that we don't spend time looking for posts that are removed. I think by so doing the number of duplicate posts and mistakes from users can be minimized. The reason is i spent hours searching through the posts to locate my posts that you have re/moved. That is why i was a little bit upset. Sorry if here is the wrong place to post my suggestion. Point me to the right place. Thanks for your work.

  • Will this be garbage collected in JVM?

    - by stjowa
    I am running the following code every two minutes via a Timer: object = new Object(this); Potentially, this is a lot of objects being created and a lot of objects being overwritten. Do the overwritten objects get garbage collected, even with a reference to itself being used in the newly created object? I am using JDK 1.6.0_13. Thanks for the help.

  • log file not generated while accessing a jar having log4j support.

    - by naveen garimella
    I have a x.jar which is being used by some client y.jar. Both x.jar and y.jar are at the same package level. i have put the log4j.xml at the same package level. But the log file is never generated. Can i know why? I have tried few other options as well but no luck till now. i have added log4j-1.2.16.jar to ClassPath: variable in manifest files of both x.jar and y.jar. Put log4j.xml at the class level of y.jar which actually calls the x.jar classes. package structure is as follows: x.jar --manifest.mf has a entry ClassPath:log4j-1.2.16.jar y.jar --manifest.mf has a entry ClassPath:log4j-1.2.16.jar log4j-1.2.16.jar log4j.xml --has a RollingFileAppender. Can any one suggest whether i am missing anything?

  • Commons VFS and IBM MVS System

    - by Liming
    Hello All, I'm using Apache Commons VFS / SFTP, we are trying to download files from the IBM MVS system. The download part is all good, however, we can not open up the zipped files after downloading. Seems like the zip file was compressed using a different algorithm or something Anyone has any pointers? *Note, the same function works fine if we connect to a regular unix/linux SFTP server. Below is an example of what we did String defaultHost = "[my sftp ip address]"; String host = defaultHost; String defaultRemotePath = "//__root.dir1.dir2."; String remotePath = defaultRemotePath; String user = "test"; String password = "test"; String remoteFileName = "Blah.ZIP.BLAH"; log.info("FtpPojo() begin instantiation"); FileObject localFileObject = fsManager.resolveFile("C:/Work/Blah.ZIP.BLAH"); log.debug("local file name is :"+localFileObject.getName().getBaseName()); log.debug("FtpPojo() instantiated and fsManager created"); String uri = createSftpUri(host, user, password) + ":322"+remotePath+remoteFileName; remoteRepo = fsManager.resolveFile(uri, fsOptions); remoteRepo.copyFrom(localFileObject, Selectors.SELECT_ALL);

  • Aggregation, Association and Composition (examples of code given)

    - by Bukocen
    I have such a simple example: public class Order { private ArrayList<Product> orders = new ArrayList<Product>(); public void add(Product p) { orders.add(p); } } Is it aggregation or composition? I guess it's composition, because orders will be delated after delete of Order, right? Unfortunately it was a task and answer was different;/ Do you know why? second problem: public class Client extends Person { String adress = ""; Orders orders = new Orders(); public Client(String n, String sn) { name = n; surName = sn; } public String getAddress() { return adress; } public Orders getOrders() { return this.orders; } } Is it Association between Client and Orders? My teacher told me that this is association, but I was wondering why it's not a aggregation/composition - he told me that aggregation or composition occur only when one class contains few instances of different class - is that right? I guess not, because e.g. car contains ONE wheel and it's aggregation I guess? What type of relation is that and why? Greetings

  • Backing Bean not getting values sent by javascript

    - by Developer106
    I have three drop down lists whose values are been copied to <h:inputHidden> components by the following JavaScript function: function getBirthDate() { var months = document.getElementById("months") var hidden1 = document.getElementById("formsignup:monthField"); hidden1.value = months.options[months.selectedIndex].text; var days = document.getElementById("days"); var hidden2 = document.getElementById("formsignup:dayField"); hidden2.value = days.options[days.selectedIndex].value; var years = document.getElementById("years"); var hidden3 = document.getElementById("formsignup:yearField"); hidden3.value = years.options[years.selectedIndex].value; } Here are the three <h:inputHidden> components: <h:inputHidden value="#{signupBean.month}" id="monthField"/> <h:inputHidden value="#{signupBean.day}" id="dayField"/> <h:inputHidden value="#{signupBean.year}" id="yearField"/> This is the command button that is supposed to invoke the function that copies the values to the inputs and then submits them to the backing bean. <h:commandButton image="images/images/signup1.png" styleClass="joinnow" id="joinus" action="#{signupBean.save}" onclick="getBirthDate()" /> But they arrive as null in the backing bean. How is this caused and how can I solve it?

  • Can a plain servlet be configured to as a seam component?

    - by stacker
    I created a plain servlet within a seam-gen (2.1.2) application, now I would like to use injection. Thus I annotated it with @Name and it's recognized as component: INFO [Component] Component: ConfigReport, scope: EVENT, type: JAVA_BEAN, class: com.mycompany.servlet.ConfigReport Unfortunatly the injection of the logger doesn't work NullPointerException in init() import org.jboss.seam.annotations.Logger; import org.jboss.seam.annotations.Name; import org.jboss.seam.log.Log; @Name("ConfigReport") public class ConfigReport extends HttpServlet { @Logger private Log log; public void init(ServletConfig config) throws ServletException { log.info( "BOOM" ); } } Is my approach abusive? What would be the alternatives (the client sending requests to the servlet is curl, not a browser)?

  • What would a compress method do in a hash table?

    - by Bradley Oesch
    For an assignment I have to write the code for a generic Hash Table. In an example Put method, there are two lines: int hash = key.hashCode(); // get the hashcode of the key int index = compress(hash); // compress it to an index I was of the understanding that the hashCode method used the key to return an index, and you would place the key/value pair in the array at that index. But here we "compress" the hash code to get the index. What does this method do? How does it "compress" the hash code? Is it necessary and/or preferred?

    - by yrajabi
    I want to enter string " -< " in strings.xml file, the string has character < and I couldn't add it to xml file without error! I even tried to escaping by \ character: <string name="search_target_arrow"> -\< </string> or enclosing it between "" as below: <string name="search_target_arrow">" -< "</string> but none worked. Maybe I'm very amateur at this and the answer is not hard for you. so please tell me how you add such special chars in strings.xml?

  • How to code the set method of a Map with another Map as value?

    - by Nazgulled
    I normally do this to set a new Map to a private variable: public static void setListaClausulas(Map<String, Clausula> nvLista) { listaClausulas = new TreeMap<String, Clausula>(nvLista); } I suppose this is ok to set a new copy of the nvLista and all it's members and not a reference, is it? But now I have a Map inside another Map and I'm doing this: public static void setListaClausulas(Map<String, Map<String, Clausula>> nvLista) { listaClausulas = new TreeMap<String, Map<String, Clausula>>(nvLista); } Is this the correct way to do it or do you recommend something else? What I want is to set a new copy of nvLista (and all it's elements) and not copy just the reference.

  • What is the common way to program action listeners?

    - by Roman
    I just started to learn how to use action listeners. To my understanding it works in the following way: There are some classes which contains "addActionListener" method by default (for example classes for buttons). Using this method we add an action listener to an object. For example: listenedObject.addActionListener(listeningObject). When an action with the "listenedObject" is performed, the "actionPerformed" method of the "listeningObject" will be called. So, it means that when we program a class for the listeningObject, we need to put there "actionPerformed" method. What is not clear to me, should we create a new class for every object that we want to listen. It does not seem to me as an elegant solution. On the other hand, if we have one action listener class for all (or at least many) object, than we have a problem since a instance of this class will not know which object is calling the "actionPerformed" method (and we need to know that since actions performed by the actionPerformed differs depending on who is called for this method). In my opinion, for every listened object we need to create are "personal" action listener and we can do it by setting a specific value to the corresponding field of the action listener. But I am not sure that it is a standard way to go? How do usually people do it?

  • Php security question

    - by Camran
    I have a linux server, and I am about to upload a classifieds website to it. The website is php based. That means php code adds/removes classifieds, with the help of the users offcourse. The php-code then adds/removes a classified to a database index called Solr (like MySql). Problem is that anybody can currently access the database, but I only want the website to access the database (solr). Solr is on port 8983 as standard btw. My Q is, if I add a rule in my firewall (iptables), to only allow connections coming from the servers IP to the Solr port nr, would this solve my issue? Thanks
