  • Handling newline character in input between Windows and Linux

    - by Fazal
    I think this is a standard problem which may have been asked before but I could not get the exact answer so posting the issue. The issue is that our server is running on a linux box. We access the server over the browser on a window box to enter data into field which is supposed to contain multiple lines which user can enter by pressing the enter key after each line Abc Def GHI When this input field (this is a text area),is read on the linux machine, we want to split the data based on new line character. I had three question on this. Does the incoming data contain "\r\n" or "\n" If incoming data does contain "\r\n", the linux line.separator property (vm property) would not work for me as it would say "\n" and therefore may leave "\r" in the data. If "\r" is left in the data, if I open the file on a windows machine, will this mean a newline character? Finally can anyone tell me the standard way to deal with this issue?

  • Looking for detailed explanation of Hibernate UserType methods for mutable objects

    - by Tom
    I am creating a custom UserType class in Hibernate. The specific case is for an HL7v3 clinical document (I work in health IT). It is a mutable object and most of the documentation around the Hibernate UserType interface seems to center around immutable types. I want a better understanding of how and when the interface methods are used, specifically: assemble - why two parameters (one Serializable, one Object)? What is the use case for this method? disassemble - should I just implement this method to return a serializable form (e.g. String representation)? When and how is this method invoked? equals - is this for update? read? contention? dirty reads? What are the consequences of simply returning false in most cases? replace - I really don't understand where the three Object parameters come from, when this method is invoked, and what Hibernate expects to return, or how that return value is used. Any pointers would be appreciated. I've searched and read all I can find on the subject, but have not found much documentation at all explaining how these methods are used for mutable objects.

  • Question concerning SCJP-6 exam

    - by abatishchev
    While preparing for the SCJP-6 exam I faced with a difficult issue. I can’t find answer by myself. Please, answer for the question and give short comments: abstract class A<K> extends Number> { // insert code here } public abstract <K> A<? extends Number> useMe(A<? super K> k); public abstract <K> A<? super Number> useMe(A<? extends K> k); public abstract <K> A<K> useMe(A<K> k); public abstract <V extends K> A<V> useMe(A<V> k); public abstract <V super K> A<V> useMe(A<V> k); public abstract <V extends Character> A<? super V> useMe(A<K> k); public abstract <V super Character> A<? super V> useMe(A<K> k); Which method can be inserted in a placeholder above? P.S. I tried to look on the specification. Those one was not helpful for me.

  • Accessing property file through batch script

    - by Farid
    Hi everyone, I'm trying to write a batch script, this script is responsible to launch a jar with one parameters. This parameter indicate to my jar wich property file to use in order to setup some configuration. Then the script will zip the results produced by the jar and send them to a location. But in order to set the name of the zip file I would need to be able to read the property file directly from the batch, is there a way to do so ? Thanks and regards, F

  • System.out.println() does not operate in Akka actor

    - by faisal abdulai
    I am kind of baffled by this encointer. I am working an akka project that was created as a maven projecct and imported into eclipse using the mvn eclipse:eclipse command. the akka actor has the system println method just to make it easy to do read the functions and methods invoked. However any time I run the akka system, the println command does not print any thing to the eclipse console but I do not get any error messages. does any one have any idea about this. below is a code snippet. public class MasterActor extends UntypedActor { /** * */ ActorSystem system = ActorSystem.create("container"); ActorRef worker1; //public MasterActor(){} @Override public void onReceive(Object message) throws Exception { System.out.println(" Master Actor 5"); if(message instanceof GesturePoints) { //GesturePoints gp = (GesturePoints) message; System.out.println(" Master Actor 1"); try { worker1.tell(message, getSelf()); System.out.println(" Master Actor 2"); } catch (Exception e) { getSender().tell(new akka.actor.Status.Failure(e), getSelf()); throw e; } } else{ unhandled(message);} } public void preStart() { worker1 = getContext().actorFor("akka://[email protected]:2553/user/workerActor"); } } don't know whether it is a bug in eclipse. thank you.

  • commons-exec: Executing a program on the system PATH?

    - by Stefan Kendall
    I'm trying to execute a program (convert from ImageMagick, to be specific) whose parent folder exists on the path. Ergo, when I run convert from the command line, it runs the command. The following, however, fails: String command = "convert" CommandLine commandLine = CommandLine.parse(command); commandLine.addArgument(...) ... int exitValue = executor.execute(commandLine); If I specify the full path of the convert executable (C:\Program files\...) then this code works. If I don't do this, I get an exception thrown with exit value 4. How do I get commons-exec to recognize the system path?

  • ivy dependency on external JAR

    - by Misha Koshelev
    Dear All: I am battling with Ivy (I tried maven but had an event more difficult time setting up the JBoss repository for Hibernate). Quick question - I am using this wonderful package: http://ooweb.sourceforge.net/index.html Unfortunately, the JAR is only available through Sourceforge: http://sourceforge.net/projects/ooweb/files/ooweb/0.8.0/ooweb-0.8.0-bin.tar.gz/download Is there a way to get Ivy to download a specific JAR? For that matter, is it possible to do with Maven? Thank you! Misha

  • Colouring JTree's TreeNodes

    - by Amadan
    I have a JTree which I give objects that implement the TreeNode interface, and a custom TreeModel to display them (not using DefaultMutableTreeNode). I would like to change the text colour of some nodes. I can't find anything in the docs, except javax.swing.tree.DefaultTreeCellRenderer.setTextNonSelectionColor(Color newColor), but it will change everything indiscriminately, and I only need it for some nodes (specifically, broken links, i.e. nodes whose corresponding files can't be found on the disk, should be greyed out, the rest should be default). Can it be done, and how?

  • GAE/J: unable to register a custom ELResolver

    - by dfa
    I need to register a custom ELResolver for a Google App Engine project. Since it must be registered before any request is received, as specified by the Javadoc: It is illegal to register an ELResolver after the application has received any request from the client. If an attempt is made to register an ELResolver after that time, an IllegalStateException is thrown. I'm using a ServletContextListener: public class RegisterCustomELResolver implements ServletContextListener { @Override public void contextInitialized(ServletContextEvent sce) { ServletContext context = sce.getServletContext(); JspApplicationContext jspContext = JspFactory.getDefaultFactory().getJspApplicationContext(context); jspContext.addELResolver(new MyELResolver()); } ... } The problem is that JspFactory.getDefaultFactory() returns always null. I've alreay filled a bug report. Any idea for a workaround?

  • Hibernate orm for a view

    - by EugeneP
    How do you ORM a view? Is there any difference with a table in terms of reverse engineering? In my case, I have a whole pile of joined tables that will be read-only in an application. So, if I need sort of a 1 Object with all collections in proper order, instead of long chains of relationships - collection with another etc, it'll be simpler. What do you think and how do you accomplish this?

  • String.substring(index) has stoped my thread in debug mode.

    - by Arkaha
    Hello! I work with j2me polish 2.0.7, in eclipse 3.4.2, with wtk2.5.2_01. I create control which draws text: normal, bold, and italic. The code below is parsing raw text, and search for * and _ symbols, if found than add to draw vector the text and the drawer, and it's just stops after getting second time to the line 58: String test = new String(raw_text_buff.substring(iter)); it stops in raw_text_buff.substring(iter), ONLY in debug mode.. raw text is: bla bla bla *1000* bla bla Full code: private String raw_text = "bla bla bla *1000* bla bla"; Vector draw_items = null; private void prepareText() { char open_char = 0; int open_pos = 0; Object []param = null; StringBuffer sb = new StringBuffer(); String raw_text_buff = new String(raw_text); int iter = 0; boolean was_reset = false; while(true) { char c = raw_text_buff.charAt(iter); if(iter == raw_text_buff.length() || c == '*' || c == '_') { if(sb.length() > 0) { BmFont viewer = null; String str = sb.toString(); if(open_char == '*' && null != bm_strong) { viewer = bm_strong.getViewer(str); }else if(open_char == '_' && null != bm_italic) { viewer = bm_italic.getViewer(str); }else if(null != bm_normal) { viewer = bm_normal.getViewer(str); }else { } param = new Object[2]; param[0] = str; param[1] = viewer; if(null == draw_items) draw_items = new Vector(); draw_items.addElement(param); sb = new StringBuffer(); if(open_char == 0 && (c == '*' || c=='_')) open_char = c; else open_char = 0; String test = new String(raw_text_buff.substring(iter)); // stucks here. raw_text_buff = test; iter = 0; was_reset = true; }else { open_char = c; } if(iter == raw_text_buff.length()) break; }else { sb.append(c); } ++iter; } } What I'm doing wrong?

  • Problem making ant compile my classes present in different Eclipse projects into single destination

    - by KCore
    I have close to about 20 projects in my Eclipse workspace. They are interdependent. Now I want to build all of them in a single war file. The thing is eclipse does it nicely... if I create a Dynamic Web Project and link sources of all the 20 projects. But I want to automate the entire process and want to be able to run a script (ant maybe..) and deploy a war in my app server. My approach: I started with a simple approach. I tried to sequentially build each project (javac task) with destination directory as web-inf of my war. But it is giving me weird errors like : package " ** " not found,when it shows the same all the required classes in classpath (I used verbose) Do you think, a continous integration engine will be better for my case (20 projects..) I saw Team City, but didnt get it the first time...

  • Get highest frequency terms from Lucene index

    - by Julia
    Hello! i need to extract terms with highest frequencies from several lucene indexes, to use them for some semantic analysis. So, I want to get maybe top 30 most occuring terms(still did not decide on threshold, i will analyze results) and their per-index counts. I am aware that I might lose some precision because of potentionally dropped duplicates, but for now, lets say i am ok with that. So for the proposed solutions, (needless to say maybe) speed is not important, since I would do static analysis, I would put accent on simplicity of implementation because im not so skilled with Lucene (not the programming guru too :/ ) and cant wrap my mind around many concepts of it.. I can not find any code samples from something similar, so all concrete advices (code, pseudocode, links to code samples...) I will apretiate very much!!! Thank you!

  • How can I use Hibernate Criteria's to query nested tables?

    - by cbmeeks
    I've looked all over SO and Google but I guess I'm not using the right search terms or something. Anyway, say I have three tables: Companies ----------------------------------------- id name user_id Users ----------------------------------------- id username usertype_id UserTypes ----------------------------------------- id typeofuser So ACME would be a company, it would have a user Moe and Moe would be a usertype of Stooge. In SQL, I would do something like: select * from companies c join users u on (u.id = c.user_id) join usertypes ut on (ut.id = u.usertype_id) where ut.typeofuser = 'Stooge' But I can't seem to figure out how to do that in a Criteria. I have tried: Criteria crit = io.getSession().createCriteria(Company.class); List<Company> list = crit.createCriteria("users") .createCriteria("usertypes") .add(Restriction.eq("typeofuser", "Stooge").list(); But I get back way too many records. And the results don't even come close to being accurate. I've also tried: Criteria crit = io.getSession().createCriteria(Company.class); List<Company> list = crit.createAlias("users", "u") .createAlias("u.usertypes", "ut") .add(Restriction.eq("ut.typeofuser", "Stooge").list(); Seems to bring back the exact same result set. I actually have read the user manual. And when I nest only one level deep (ie, searching by users is fine) but when I get two layers deep, I can't quite get it. And the manual is no help. I just can't relate cats and kittens to business objects. Maybe they should use cats, kittens and fleas? :-/ Thanks for any suggestions.

  • Spring 3 MVC - how to turn a form into a query string?

    - by caerphilly
    I have a simple Spring form that gets bound to a form object on post. The http POST handler does some work, and then needs to redirect to a new URL, passing the form data as querystring parameters. So, assuming I have a form backing object with properties "param1" and "param2", I want to build a string that looks something like this: redirect:/app/new/page?param1=value;param2=value Now, Spring will automatically bind values FROM a querystring or a form post into my form object, but I want to GENERATE a querystring with values taken from the form object. Obviously it's trivial to do this manually but since I'm going to have lots of different form backing objects, is there some built-in facility in Spring to generate a query string from a form object, suitable for building into a URL? Thanks.

  • How to run red5 apps on a remote server?

    - by domi
    I've got a really nasty problem... I wrote a red5 app and so on and it is running perfectly on my local computer. Now the problem occurs = How can I make this program work on a remote server? Local : OSX 10.5 - red5 0.63 Server: CentOS 5 - red5 0.90 Maybe its because of the version difference... but I can't test red5 0.90 locally becaus it won't start up -.-' and I can't install the 0.63 on the server because of missing dependencies (and broken links to them...)

  • Eclipse and Cassandra

    - by H2oNinja
    I've searched various websites for instructions on how to link 'Cassandra' and 'Eclipse' and followed directions to the last detail in several sites. For some reason, while using Git Bash, I cant get through the 'ant build', via instruction in said mentioned locations across the web. In some location's its easy, just make sure you have; 1. Apache Cassandra source 2. Apache Ant 3. Git So, yeah I've downloaded all the above, tried the same directory, different directories, etc., although still unable to get past the middle step of 'ant build'. Here are a few websites I've used to muddle through setting up the Src code for both utilities, 'Eclipse' and 'Cassandra'. http://uisurumadushanka89.blogspot.com/2012/02/apache-cassandra-how-to-setup-source.html and http://wiki.apache.org/cassandra/RunningCassandraInEclipse both resulting in an immediate halt at the 'ant build'. any insights are information is greatly appreciated. Thank-you, Ryan
