  • Generating JavaDoc style documentation

    - by Walter White
    Hi all, I would like to generate a report similar to JavaDoc so that you can real easily click on a test, result, and source. I am running HtmlUnit tests so I will have the result (html), source (request, headers, parameters, etc.), stack trace all visible so a developer or qa can go back later to review this to see what went awry. So, in the left frame, the tests will be listed along with the group they were a part of (similar to packages in javadoc). In the right frame, the results will be presented along with the source and stack trace. How can I achieve this? The HtmlUnit tests are part of the project and not a stand-alone plugin if that matters. Thanks, Walter

  • Plugin or module for filtering/sorting a large amount of data?

    - by prometheus
    I have a rather large amount of data (100 MB or so), that I would like to present to a user. The format of the data is similar to the following... Date              Location      Log File          Link 03/21/2010   San Diego   some_log.txt   http://somelink.com etc My problem is that I would like to have some nice/slick way for the user to filter the information. Unfortunately, because there is so much of it, the jQuery Table Filter plugin does not work (crashes the browser). I was wondering if there is a nice solution or if I have to simply do the filtering on the server end and have a bland pull-down menu / select-box interface for the client to use.

  • How convince other developers not to ignore Exceptions?

    - by Mnementh
    Recently I encountered a bug in an application I took over from another developer. I debugged for the reason and over an hour later I realized, that the problem wasn't the code producing the exception, but some code executed before this returning wrong data. If I dived into this, I encountered the following: try { ... } catch (XYException e){} If the Exception would have been propagated (a change I did), I would have found the reason for the bugs in a few minutes, as the stacktrace had pointed me to the problem. So how can I convince other developers to never catch and ignore exceptions in this way?

  • Deploying spring message driven pojo on weblogic 8.1

    - by Igman
    Hello, I am trying to deploy a spring message message driven POJO on weblogic 8.1. It is a simple POJO, and it works fine being run outside of an application server, but the messages do not seem to be picked up at all. I have created empty home and remote interfaces, as well as a container bean class that contains an instance of the pojo which it gets from the application context. I then added this container bean class to the ejb-jar.xml as a . I have not been able to get the messages pick up. Does anyone have any suggestions as to what I am doing wrong? Could anyone point me to a tutorial on how to deploy a MDP? Thanks.

  • Dynamic Typed Table/Model in J2EE?

    - by Viele
    Hi, Usually with J2EE when we create Model, we define the fields and types of fields through XML or annotation before compilation time. Is there a way to change those in runtime? or better, is it possible to create a new Model based on the user's input during the runtime? such that the number of columns and types of fields are dynamic (determined at runtime)? Help is much appreciated. Thank you.

  • Variable 'app' in url-pattern for servlet mapping

    - by Brian
    I'm learning Spring MVC (and servlets in general) and following springsource's mvc-ajax example, which uses annotated controller methods. It appears that there is only one url-pattern (in web.xml) mapped to a servlet in that example: /app/* I've deployed the app as a WAR file, and the actual, ugly URL I'm requesting is http://127.0.0.1:8080/org.springframework.samples.mvc.ajax-1.0.0-20100407.233245-1/account. So, it appears that 'app' in '/app/*' is a variable corresponding to 'org.springframework.samples.mvc.ajax-1.0.0-20100407.233245-1', however, it isn't universal because it isn't usable in my own app, and it contradicts my understanding that url-pattern contains the portion of the URL after the app name. So, what is 'app'? Where is it configured?

  • Help regarding composite pattern with hibernate

    - by molleman
    Hello, So i am stuck, i am creating a gwt web application, i will be using a tree(gwt Tree and TreeItems) structure to show a list of folders(class Folder) and files(class FileLocation), the folder and filelocation class will all implement a Hierarchy interface basing the classes on the composite pattern. but i am using hibernate to store my data , and i am using annotations for the mapping of the data to the database. my trouble is i do not know how to annotate my interface. have any of you guys used the composite pattern while persisting the data with hibernate public interface Hierarchy(){ // a few abstract methods that will be implemented by the sub classes } @Entity @Table() public class Folder extends Hierarchy implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "folder_id", updatable = false, nullable = false) private int id; @OneToMany(cascade = CascadeType.ALL,fetch = FetchType.EAGER) @JoinTable(name = "FOLDER_FILELOCATION", joinColumns = { @JoinColumn(name = "folder_id") }, inverseJoinColumns = { @JoinColumn(name = "file_information_id") }) private List<Hierarchy> children = new ArrayList<Hierarchy>() ; @Column(name = "folder_name") private String folderName; @Column(name = "tree_item") private TreeItem item; @Column (name = "parent") private Hierarchy parent; @Entity @Table(name = "FILE_INFORMATION_TABLE") public class FileInformation extends Hierarchy implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "file_information_id", updatable = false, nullable = false) private int fiId; @Column (name = "location") private String location; @Column(name = "tree_item") private TreeItem item; @Column (name = "parent") private Hierarchy parent;

  • Issue with multipart upload in servlet on seam

    - by stacker
    I created a servlet wich works fine when deployed in a separate war file, but I intend to use it as part of a seam application. I use commons-fileupload but the iterator (see snippet) returns false (only when included in the seam-app). Any ideas? protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { try { String action = request.getParameter( "action" ); if ( ServletFileUpload.isMultipartContent( request ) ) { log.info( "MULTIPART" ); } ServletFileUpload upload = new ServletFileUpload(); FileItemIterator iter = upload.getItemIterator( request ); // --------- hasNext() returns false, only in seam ----------- while ( iter.hasNext() ) { ...... } Additional Info: I don't want to use the technique described here since the uploading client is curl. The HttpServletRequest is wrapped by org.jboss.seam.web.IdentityRequestWrapper Using the seam

  • how to settle JSF combobox with values depending on another combobox if both are set to required

    - by mykola
    Hi, everybody! Can anyone tell me how to automatically set <h:selectOneMenu (or any other component) with values depending on another <h:selectOneMenu if there empty elements with 'required' set to 'true' on the form? If to set <a4j:support event="onchange" reRender="anotherElement" immediate="true"/ then nothing is changed because changed value isn't set. But without immediate i always have message that this or that element cannot be empty. Here's code example that doesn't work :) <h:outputLabel value="* #{msg.someField}: "/> <h:panelGrid cellpadding="0" cellspacing="0"> <h:selectOneMenu id="someSelect" value="#{MyBean.someObj.someId}" required="true" label="#{msg.someField}" > <a4j:support event="onchange" reRender="anotherSelect" limitToList="true" immediate="true"/> <f:selectItem itemValue=""/> <f:selectItems value="#{MyBean.someList}"/> </h:selectOneMenu> <rich:message for="someSelect" styleClass="redOne"/> </h:panelGrid> <h:outputLabel value="* #{msg.anotherField}: "/> <h:panelGrid cellpadding="0" cellspacing="0"> <h:selectOneMenu id="anotherSelect" value="#{MyBean.someObj.anotherId}" required="true" label="#{msg.anotherField}" > <f:selectItem itemValue=""/> <f:selectItems value="#{MyBean.anotherList}"/> </h:selectOneMenu> <rich:message for="anotherSelect" styleClass="redOne"/> </h:panelGrid> <h:outputLabel value="* #{msg.name}: "/> <h:panelGrid cellpadding="0" cellspacing="0"> <h:inputText id="myName" value="#{MyBean.someObj.myName}" required="true" label="#{msg.name}"/> <rich:message for="myName" styleClass="redOne"/> </h:panelGrid> So, here (i repeat), if i try to change 'someSelect' then 'anotherSelect' should update its values but it doesn't because either when it tries to get value of 'someSelect' it gets null (if immediate set to 'true') or form validation fails on empty elements. How can i skip validation but get this changed value from 'someSelect'?

  • Mocking an object that uses jni using EasyMock

    - by Visage
    So my class under test has code that looks braodly like this public void doSomething(int param) { Report report = new Report() ...do some calculations report.someMethod(someData) } my intention was to extract the construction of report into a protected method and override it to use a mock object that I could then test to ensure that someMethod had been called with the right data. So far so good. But Report isnt under my control, and to mkae things worse it uses JNI to load a library at runtime. If I do Report report = EasyMock.createMock(Report.class) then EasyMock attempts to use reflection to find out the class members, but this causes an attempt to load the JNI library, which fails (the JNI libraries are only available on UNIX). Im considering two things: a) Introduce a ReportWrapper interface with two implementations, one of which will delegate calls to an real Report (so basically a Proxy), and a second which will basically use a mock object. or b) instead of calling someMethod, call a protected method which will in turn call someMethod that I can override in a testing subclass. Either way it seems nasty. Any better ways?

  • GridView: How can I get rid of extra space from my GirdView object?

    - by Lajos Arpad
    Hello, I'm writing an application for Android phones for Human vs. Human chess play over the internet. I was looking at some tutorials, to learn how to develop Android applications and found a very nice example of making galleries (it was a GridView usage example for making a gallery about dogs) and the idea came to draw the chess table using a GridView, because the example project also handled the point & click event and I intended to use the same event in the same way, but for a different purpose. The game works well (currently it's a hotseat version), however, I'm really frustrated by the fact that whenever I rotate the screen of the phone, my GridView gets hysterical and puts some empty space in my chess table between the columns. I realized that the cause of this is that the GridView's width is the same as its parent's and the GridView tries to fill its parent in with, but there should (and probably is) be a simple solution to get rid of this problem. However, after a full day of researching, I haven't found any clue to help me to make a perfect drawing about my chess table without a negative side effect in functionality. The chess table looks fine if the phone is in Portrait mode, but in Landscape mode it's far from nice. This is how I can decide whether we are in Portrait or Landscape mode: ((((MainActivity)mContext).getWindow().getWindowManager().getDefaultDisplay().getWidth()) < ((MainActivity)mContext).getWindow().getWindowManager().getDefaultDisplay().getHeight()) In the main.xml file the GridView is defined in the following way: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <GridView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/gridview" android:layout_width="wrap_content" android:layout_height="wrap_content" android:numColumns="8" android:verticalSpacing="0dp" android:horizontalSpacing="0dp" android:stretchMode="columnWidth" android:gravity="center" > </GridView> ... </LinearLayout> I appreciate any help with the problem and thank you for reading this.

  • Amount of data stored in session

    - by srinannapa
    What technique should we use to make the httpsession object not loaded heavily with data. Example : Request 1 ---- httpSession loaded with an arraylist of 50,000 different objects. session.setAttribute("data",arraylist); Request 2 ---- httpSession loaded with an arraylist of 40,000 different objects. session.setAttribute("data",arraylist); Assume the server is loaded heavily with multiple sessions and huge data in them. Let us say from my above example request1..1000 at a time. Which means 1000 session objects with huge data. What is the alternate way to solve instead storing them in session like this?

  • Prevent SQL injection from form-generated SQL.

    - by Markos Fragkakis
    Hi all, I have a search table where user will be able to filter results with a filter of the type: Field [Name], Value [John], Remove Rule Field [Surname], Value [Blake], Remove Rule Field [Has Children], Value [Yes], Remove Rule Add Rule So the user will be able to set an arbitrary set of filters, which will result essentially in a completely dynamic WHERE clause. In the future I will also have to implement more complicated logical expressions, like Where (name=John OR name=Nick) AND (surname=Blake OR surname=Bourne), Of all 10 fields the user may or may not filter by, I don't know how many and which filters the user will set. So, I cannot use a prepared statement (which assumes that at least we know the fields in the WHERE clause). This is why prepared statements are unfortunately out of the question, I have to do it with plain old, generated SQL. What measures can I take to protect the application from SQL Injection (REGEX-wise or any other way)?

  • JAXB, marshalling sub-class that has the same rootNode name as the superclass

    - by SCdF
    Let's say I have this: public class Foo { private String value; // <snip> getters and setters, constructors etc } And I also have this: public class Bar extends Foo { private String anotherValue; // <snip> getters and setters, constructors etc } I want to be able to marshall this to a Bar object: <foo> <value>smang</value> <anotherValue>wratz</anotherValue> </foo> I'm not in a position to check right now, but if I change the @XmlRootNode name of Bar to 'foo' will that work? Do I have to do anything more clever than that?

  • How to manually query LDAP through Acegi's beans?

    - by Veggen Skrikk
    I have an application using Acegi (earlier version of Spring Security) and LDAP for logins. Now, a specific scenario requires me to discover user's LDAP groups at arbitrary time (not at login time). Is it possible to use already set up Acegi to handle this situation? I'm thinking of using the configured LdapAuthProvider (or LdapAuthPopulator or whatever's appropriate) to get all the groups associated with a given username. Is this possible? If yes, please, please, give some hints how it should be done...

  • How do I share a Hibernate SessionFactory across web applications?

    - by Jer
    I have two web applications that are running on a single Tomcat server and are connected to the same database with Hibernate. I am concerned that having two SessionFactory instances running around might cause some issues. Also, since both web applications share much of the same application logic, I thought it would be a good idea to centralize as much as I could. And since I use Spring for DI and Hibernate configuration it would make sense to have a single ApplicationContext as well. How would I go about doing something like this? Do I need to deploy a headless WAR that creates an ApplicationContext and thus a SessionFactory and allow each application access to it? Is this even a good idea?
