• Sorting a text file by date - Date looks like DD/MM/YYYY

  - by John N

  I am trying to sort the dates from the earliest to the latest. I was thinking about using the bufferedreader and do a try searching the first 2 characters of the string and then the 4th and 5th characters and finally the 7th and 8th characters, ignoring the slashes. The following is an example of the text file I have: 04/24/2010 - 2000.0 (Deposit) 09/05/2010 - 20.0 (Fees) 02/30/2007 - 600.0 (Deposit) 06/15/2009 - 200.0 (Fees) 08/23/2010 - 300.0 (Deposit) 06/05/2006 - 500.0 (Fees)

• Setting JMX attribute on VM as command line paramater

  - by 117440226733149663383

  I've done some searching, but can't seem to find a way to do this. We'd like to proactively monitor our permgen space via JMX. It seems the best way to do this is through the UsageThreshold attribute on the "PS Perm Gen" MemoryPool. By default, this is set to 0. Is there a way to specify this, or any JMX attribute, as a -D parameter to VM so this can be set automatically at startup? Or is there another mechanism to load JMX attributes automatically? Thanks.

• Cross field validation in jsf h:datatable using p:calendar

  - by Matt Broekhuis

  I noticed this question was asked, but it has not been answered correctly. I have a datatable that has two columns start date and end date. Both contain primefaces p:calendar controls in them. I need to ensure that for each row that the date in column1 is not after the date in column2. I would like to tie this into the JSF validation framework, but I'm having trouble. i've tried marking the datatable rowStatePreserved="true" , this allows me to get the values, but something is still wrong as when it fails, all the values in the first row overwrite all the other values. What am I doing wrong, or should I be using a completely different strategy? xhtml code <h:form> <f:event type="postValidate" listener="#{bean.doCrossFieldValidation}"/> <p:dataTable id="eventDaysTable" value="#{course.courseSchedules}" var="_eventDay" styleClass="compactDataTable" > <p:column id="eventDayStartColumn"> <f:facet name="header"> Start </f:facet> <p:calendar id="startDate" required="true" value="#{_eventDay.startTime}" pattern="MM/dd/yyyy hh:mm a"/> </p:column> <p:column id="eventDayEndColumn"> <f:facet name="header"> End </f:facet> <p:calendar id="endDate" required="true" value="#{_eventDay.endTime}" pattern="MM/dd/yyyy hh:mm a"/> </p:column> </p:dataTable> </h:form> validationCode public void doCrossFieldValidation(ComponentSystemEvent cse) { UIData eventsDaysStable = (UIData) cse.getComponent().findComponent("eventDaysTable"); if (null != eventsDaysStable && eventsDaysStable.isRendered()) { Iterator<UIComponent> startDateCalendarIterator = eventsDaysStable.findComponent("eventDayStartColumn").getChildren().iterator(); Iterator<UIComponent> endDateCalendarIterator = eventsDaysStable.findComponent("eventDayEndColumn").getChildren().iterator(); while (startDateCalendarIterator.hasNext() && endDateCalendarIterator.hasNext()) { org.primefaces.component.calendar.Calendar startDateComponent = (org.primefaces.component.calendar.Calendar) startDateCalendarIterator.next(); org.primefaces.component.calendar.Calendar endDateComponent = (org.primefaces.component.calendar.Calendar) endDateCalendarIterator.next(); Date startDate = (Date) startDateComponent.getValue(); Date endDate = (Date) endDateComponent.getValue(); if (null != startDate && null != endDate && startDate.after(endDate)) { eventScheduleChronologyOk = false; startDateComponent.setValid(false); endDateComponent.setValid(false); } } if (!eventScheduleChronologyOk) { showErrorMessage(ProductManagementMessage.PRODUCT_SCHEDULE_OUT_OF_ORDER); } } }

• How to create an aspect on class, that is not a bean using Spring AOP?

  - by Ula Krukar

  Hello, I work on an legacy application, where Spring AOP (namely ProxyFactoryBean) is used. I need to add an aspect around a method of a certain class. This class is not a bean however. The AspecjJ pointcut expression would be like this: execution(* xyz.package.Class.method()) I created a MethodInterceptor and AspectJExpressionPointcut, but I don't know how make those two work together. EDIT: I do not have source code for this class, it is a 3rd party library. The instances of this class are not created by me, neither in source code, nor in spring configuration as beans. It is used internally by the library. Any help appreciated.

• GridLayout with single column

  - by Albinoswordfish

  Right now I'm trying to use a GridLayout with only a single column. However I'm having a problem where I don't want the object, in this case a JButton, to be stretched the entire width of the JPanel that it's on. Is there a way to decrease the width of the JButton so that it does not stretch the entire width of the JPanel. I've tried using setPreferredSize and setSize with no results. Is this just the way GridLayout works or is there something I'm missing?

• Strange Exception on getGeneratedKeys() with JDBC for MySQL 5.1

  - by sweeney

  Hello, I'm using JDBC to insert a row into a MYSQL database. I build a parameterized command, execute it and attempt to retrieve the auto generated keys as follows: String sql = "INSERT IGNORE INTO `users` (`email`, `pass-hash`) VALUES (?, ?)"; Connection conn = SQLAccess.getConnection(); PreparedStatement ps = conn.prepareStatement(sql); ps.setString(1, login); ps.setString(2, passHash); int count = ps.executeUpdate(); if (count == 1) { ResultSet rs = ps.getGeneratedKeys(); rs.next(); //some more stuff... } For some reason, I get the following SQLException on the line containing ResultSet rs = ps.getGeneratedKeys();: !Statement.Generated Keys Not Requested! Any thoughts? When I run the same query, as generated by running the app through the debugger, in a MySQL browser it executes without incident. Thanks, brian

• fitnesse test framework, arbitrary properties for test and queries/test runs based on them?

  - by Marcel

  hi, our testers have the requirement to store multiple properties for a test that are not present in the "properties". e.g. they want to store priority, a description(not in the wiki page itself) and so on. they don't want to use the tagging mechanism. is there a way to store any kind of new xml node in the properties.xml for a test? these properties should then be used to: query the fields via the search screen run tests based on the "SuiteResponder" ?suite=xxx&TAGx=abc&TAGy=cde they should be returned by "?properties" responder. they should appear in the test history of the test run in essence they want to store any kind of "meta" information in the properties.xml and work with them in all kinds of ways, search, run etc. does anybody here know if there is already something available in that direction? if not i think we have to "pimp" these features into fitnesse to make our testers happy. thanks a lot any help appreciated marcel ps: i've also posted the question in the yahoo fitnesse group

• 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?

• How do Tomcat examples work?

  - by Bialecki

  Alright, this is a very simple question. I just installed Tomcat 6 on my Mac to play around with it, and every tutorial I look at says the first thing to do to create a new web application is to add a line to the server.xml file with defines a new Context. Fair enough. However, my question is, I don't see a line in there for the example web applications, so how do those work?

• Why empty String is treated as null in oracle?

  - by GK

  We are using empty string in DB2 database for some business logic. but when the same record tried to insert into the Oracle it throws some not null property references to null value error. that is oracle treats empty string as null. So i am wondering why it is like that. and if there is a requirement of storing empty string how to do that on oracle?

• Advantages/disadvantages of Glassfish v3 Prelude vs Springsource dm server for Web applications?

  - by cletus

  Both of these appservers are at least in part OSGI based. One (Glassfish) is obviously J2EE while the other isn't. Now I'm at the stage of choosing a platform for a new project and the natural choice is Glassfish v3 Prelude. This does raise the issue of perhaps we should be using S2AP instead. The question then is this: does the springsource dm server offer any compelling reason to use it over Glassfish? And vice versa.

• 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?

• Are JSF 2.x ViewScoped Beans Thread Safe?

  - by Mark

  I've been googling for a couple hours on this issue to no eval. WELD docs and the CDI spec are pretty clear regarding thread safety of the scopes provided. For example: Application Scope - not safe Session Scope - not safe Request Scope - safe, always bound to a single thread Conversation Scope - safe (due to the WELD proxy serializing access from multiple request threads) I can't find anything on the View Scope defined by JSF 2.x. It is in roughly the same bucket as the Conversation Scope in that it is very possible for multiple requests to hit the scope concurrently despite it being bound to a single view / user. What I don't know is if the JSF implementation serializes access to the bean from multiple requests. Anyone have knowledge of the spec or of the Morraja/MyFaces implementations that could clear this up?

• Why a "private static" is not seen in a method?

  - by Roman

  I have a class with the following declaration of the fields: public class Game { private static String outputFileName; .... } I set the value of the outputFileName in the main method of the class. I also have a write method in the class which use the outputFileName. I always call write after main sets value for outputFileName. But write still does not see the value of the outputFileName. It say that it's equal to null. Could anybody, pleas, tell me what I am doing wrong? ADDED As it is requested I post more code: In the main: String outputFileName = userName + "_" + year + "_" + month + "_" + day + "_" + hour + "_" + minute + "_" + second + "_" + millis + ".txt"; f=new File(outputFileName); if(!f.exists()){ try { f.createNewFile(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } System.out.println("IN THE MAIN!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"); System.out.println("------>" + outputFileName + "<------"); This line outputs me the name of the file. Than in the write I have: public static void write(String output) { // Open a file for appending. System.out.println("==========>" + outputFileName + "<============"); ...... } And it outputs null.

• Problem consuming Exchange Web Service 2010 with jax-ws metro

  - by Johan Karlberg

  I am trying to consume the Exchange 2010 Web Service interface using JAX-WS. I'm using JAX-WS 2.2 RI (Metro 2.0). 2.1 exhibited the same problem. I am running into trouble with Exchange, which returns "HTTP/1.1 415 Cannot process the message because the content type 'text/xml;charset=utf-8' was not the expected type 'text/xml; charset=utf-8'." as a reponse (2.1 quoted the charset value, otherwise same response). Apparently I need to dictate the exact Content-type header for Exchange to be happy. Is there a way for me to do this without forcing me to manually rebuild the dependency? I currently rely on published maven artifacts, and would like to continue doing this if at all possible. The consuming process is a regular J2SE app, with no containers in sight. I have control of the application and can add pretty much anything required to the applications scope, but can not add out-of-process items like proxy servers. The client classes were generated from local WSDL, but the charset specification is derived from constants declared in the jaxws RI implementation, not the generated code. The resulting HTTP transport is thus handled by the standard http/https client from Sun JRE5 or JRE6.

• The fastest way to do a collection subtraction

  - by Tony

  I have two Sets. Set<B> b is the subset of Set<A> a. they're both very huge Sets. I want to subtract b from a , what's the best practice to do this common operation ? I've written to many codes like this , and I don't think it's efficient. what's your idea ? for(int i = 0 ; i < a.size(); i++) { for (int j=0 ; j < b.size() ;j++) { // do comparison , if found equals ,remove from a break; } } And I want to find an algorithm , not only applies to Sets, also works for Array.

• Spring @Autowired and WebApplicationContext in Tomcat

  - by EugeneP

  @Autowired works only once. What to do to make it wire the bean every time the Servlet is recreated? My web-app (Tomcat6 container) consists of 2 Servlets. Every servlet has private fields. Their setters are marked with @Autowired In the init method I use WebApplicationContextUtils ... autowireBean(this); It autowires the properties marked with @Autowired once - during the initialization of the Servlet. Any other session will see these fields values, they will not be rewired after the previous session is destroyed. What to do to make them rewire them each time a Servlet constructor is called? a) Put the autowiring into the constructor? Or better 2) get a web app context and extract a bean from there?

• Should services include logged in user as a parameter?

  - by Asaf Mesika

  Hi, When using the Service design pattern, do you usually place the logged in user, or user scope, as a parameter to the methods of the service interface, or do you call AutheticationService.getLoggedInUser() in the service implementation. What advantages/disadvantages do you find for each option?

• 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?

• How to make Spring accept fluent (non-void) setters?

  - by Chris

  Hi, I have an API which I am turning into an internal DSL. As such, most methods in my PoJos return a reference to this so that I can chain methods together declaratively as such (syntactic sugar). myComponent .setID("MyId") .setProperty("One") .setProperty2("Two") .setAssociation(anotherComponent) .execute(); My API does not depend on Spring but I wish to make it 'Spring-Friendly' by being PoJo friendly with zero argument constructors, getters and setters. The problem is that Spring seems to not detect my setter methods when I have a non-void return type. The return type of this is very convenient when chaining together my commands so I don't want to destroy my programmatic API just be to compatible with Spring injection. Is there a setting in Spring to allow me to use non-void setters? Chris
