  • Java - JDBC alternatives

    - by Mike
    Hello, this is just teorethical question. I use JDBC with my Java applications for using database (select, insert, update, delete or whatever). I make "manually" Java classes which will contain data from DB tables (attribute = db column). Than I make querys (ResultSet) and fill those classes with data. I am not sure, if this is the right way. But I've read lot of about JDO and another persistence solutions. Can you please recommend some? Which are modern? Will be used in the future? Some advantages of JDO over JDBC (in simple words). I've been able to google lot of this stuff, but opinions from the "first hand" are always best. Thank you for responses, Mike

  • Which Java modules get Spring Security

    - by HDave
    I have a classic Java SOA application, with a web UI module, web services module, a service module (Java API), a domain module and a persistence module. In a sense, each of these modules has their own public API. My understanding of Spring Security is that I can use web filters to handle the security of the web gui and web services, and method level security (via annotations) for the service module. My question is this: should I bother to add method level security to the domain module and the persistence module or is that considered overkill?

  • How to auto create a JMS topic/queue on JBoss in a portable and per-application way?

    - by Bozho
    It's simple: I have an MDB and an EJB that sends messages to a topic (or queue). JBoss complains that the topic is not bound to the JNDI context. I want to have the topic/queue to be automatically created at best, or at least to have a standard way to define it, per application (say, in ejb-jar/META-INF) this question and this blogpost show us how to do it in an application server specific way. This surely works, but: I want to use the @MessageDriven annotation I want the setting not to be global for the application server I want the setting to be portable

    - by Helpme
    Hi! I'm purposely targeting Java OS 1.4.2 I'm trying to use an iterator combined with apache's POI to read an excel spreadsheet. The code runs perfectly in java 1.5, but in the 1.4.2 version I get the error listed in the question subject. the code is: Iterator myIter = null; it breaks on that line of code, which is clearly at the beginning of the application. I dont understand what needs to be done to correct this issue. Please let me know if you have any insight!

  • How to access USB ports in java

    - by Petezah
    Hi I'm trying to write a java application that accesses the usb ports to some read and writes to a device connected through usb. The problem I face is that I don't know what exactly to use in java to do such a thing. I searched online a found something called jusb but all the post seem fairly old. Currently I'm using the RXTX libraries but I sometimes run into some sync error. When I use C# to do the equivalent it requires far less code and I don't face any of the same sync error. My question is there anything built into the latest version of the JRE I can use to access the usb ports that is just as easy as the equivalent C# code? Sorry if the question isn't too clear, I'm fairly noob with coding usb IO.

    Is it possible to add a folder which contains java source code as a classpath element. I have tried a few things and it seems that the classloadr is not picking up java soruce files?

  • Creating managed file transfer software in java

    - by Shekhar
    Hello, I have been asked to do some POC on how we can provide a software solution which will be able to manage files. Manage files means it will be able to move files from source to destination servers. The client gave us 4 page document detailing what sort of software they are looking for. They dont want to use existing commercial softwares. They want to build their own customizable software. Has anybody worked on this type of project? Please provide your inputs on how should i approach this project. The software should be platform independent and should be built in java.

  • How to know start and kill processes within Java code (or C or Python) on *nix

    - by recipriversexclusion
    I need to write a process controller module on Linux that handles tasks, which are each made up of multiple executables. The input to the controller is an XML file that contains the path to each executable and list of command line parameters to be passed to each. I need to implement the following functionality: Start each executable as an independent Be able to kill any of the created processes independent of the others In order to do (2), I think I need to capture the pid when I create a process, to issue a system kill command. I tried to get access to pid in Java but saw no easy way to do it. All my other logic (putting info about the tasks in DB, etc) is done in Java so I'd like to stick with that, but if there are solutions you can suggest in C, C++, or Python I'd appreciate those, too.

  • How the hell do you get clients to use your bug tracking system?

    - by louism
    on larger projects i use a simple bug tracking system thats designed to be used by clients i have a lot of trouble convincing clients to use it (they send bug reports via email) does anyone have any strategies they can suggested? also, i have been playing around with a theory as to why this is the case; it goes like this: asking a client to log a bug is like taking your car to a mechanic for a service, and the mechanic hands you the engine oil and says "here, pop that in". basically, the client has paid you to do the work, logging a bug sounds too much like work, so they want you to do it thoughts? -- LM

  • Direct comparator in Java out of the box

    - by KARASZI István
    I have a method which needs a Comparator for one of its parameters. I would like to pass a Comparator which does a normal comparison and a reverse comparator which does in reverse. java.util.Collections provides a reverseOrder() this is good for the reverse comparison, but I could not find any normal Comparator. The only solution what came into my mind is Collections.reverseOrder(Collections.reverseOrder()). but I don't like it because the double method calling inside. Of course I could write a NormalComparator like this: public class NormalComparator<T extends Comparable> implements Comparator<T> { public int compare(T o1, T o2) { return o1.compareTo(o2); } } But I'm really surprised that Java doesn't have a solution for this out of the box.
