  • Method may fail to close stream on exception

    - by 01
    I get the critical error with finbugs The method creates an IO stream object, does not assign it to any fields, pass it to other methods, or return it, and does not appear to close it on all possible exception paths out of the method. This may result in a file descriptor leak. It is generally a good idea to use a finally block to ensure that streams are closed. try { ... stdError = new BufferedReader(new InputStreamReader(p.getErrorStream())); ... } catch (IOException e) { throw new RuntimeException(e); } finally { try { if (stdInput != null) { stdInput.close(); } if (stdError != null) { stdError.close(); } } catch (IOException e) { throw new RuntimeException(e); } } do i need to close also InputStreamReader or p.getErrorStream(it returns InputStream) ??

  • HQL to get elements that possess all items in a set

    - by Tauren
    Currently, I have an HQL query that returns all Members who possess ANY Award from a set of specified Awards: from Member m left join m.awards as a where a.name in ("Trophy","Ribbon"); What I now need is HQL that will return all Members who possess ALL Awards specified in the set of Awards. So, assuming this data: Joe has Trophy, Medal Sue has Trophy, Ribbon Tom has Trophy, Ribbon, Medal The query above would return Joe, Sue, and Tom because all three possess at least one of Trophy or Ribbon. But I need to return only Sue and Tom, because they are the only ones who possess all of the specified awards (Trophy and Ribbon). Here's the class structure (simplified): class Member { private String name; private Set<Award> awards; } class Award { private String name; }

    - by Gabriele
    How can I get an existent Class from an Ontology with owlAPI? This is a fragment of my ontology: ... <owl:Class rdf:ID="StringDocu"> <owl:equivalentClass> <owl:Restriction> <owl:someValuesFrom rdf:resource="http://www.w3.org/2001/XMLSchema#string"/> <owl:onProperty rdf:resource="#hasContent"/> </owl:Restriction> </owl:equivalentClass> <rdfs:label rdf:datatype="http://www.w3.org/2001/XMLSchema#string" >String Docu</rdfs:label> <rdfs:subClassOf rdf:resource="#Docu"/> <owl:disjointWith rdf:resource="#URIDocu"/> <rdfs:comment rdf:datatype="http://www.w3.org/2001/XMLSchema#string" >This class concerns a docu with the content specified as common text.</rdfs:comment> </owl:Class> ...

  • PreparedStatement

    - by Steel Plume
    Hello, in the case of using PreparedStatement with a single common connection without any pool, can I recreate an instance for every dml/sql operation mantaining the power of prepared statements? I mean: for (int i=0; i<1000; i++) { PreparedStatement preparedStatement = connection.prepareStatement(sql); preparedStatement.setObject(1, someValue); preparedStatement.executeQuery(); preparedStatement.close(); } instead of: PreparedStatement preparedStatement = connection.prepareStatement(sql); for (int i=0; i<1000; i++) { preparedStatement.clearParameters(); preparedStatement.setObject(1, someValue); preparedStatement.executeQuery(); } preparedStatement.close(); my question arises by the fact that I want to put this code into a multithreaded environment, can you give me some advice? thanks

  • File Format DOS/Unix/MAC code sample

    - by mac
    I have written the following method to detemine whether file in question is formatted with DOS/ MAC, or UNIX line endings. I see at least 1 obvious issue: 1. i am hoping that i will get the EOL on the first run, say within first 1000 bytes. This may or may not happen. I ask you to review this and suggest improvements which will lead to hardening the code and making it more generic. THANK YOU. new FileFormat().discover(fileName, 0, 1000); and then public void discover(String fileName, int offset, int depth) throws IOException { BufferedInputStream in = new BufferedInputStream(new FileInputStream(fileName)); FileReader a = new FileReader(new File(fileName)); byte[] bytes = new byte[(int) depth]; in.read(bytes, offset, depth); a.close(); in.close(); int thisByte; int nextByte; boolean isDos = false; boolean isUnix = false; boolean isMac = false; for (int i = 0; i < (bytes.length - 1); i++) { thisByte = bytes[i]; nextByte = bytes[i + 1]; if (thisByte == 10 && nextByte != 13) { isDos = true; break; } else if (thisByte == 13) { isUnix = true; break; } else if (thisByte == 10) { isMac = true; break; } } if (!(isDos || isMac || isUnix)) { discover(fileName, offset + depth, depth + 1000); } else { // do something clever } }

  • Eclipselink read complex object model in an ordered way

    - by Raven
    Hi, I need to read a complex model in an ordered way with eclipselink. The order is mandantory because it is a huge database and I want to have an output of a small portion of the database in a jface tableview. Trying to reorder it in the loading/quering thread takes too long and ordering it in the LabelProvider blocks the UI thread too much time, so I thought if Eclipselink could be used that way, that the database will order it, it might give me the performance I need. Unfortunately the object model can not be changed :-( The model is something like: @SuppressWarnings("serial") @Entity public class Thing implements Serializable { @Id @GeneratedValue(strategy = GenerationType.TABLE) private int id; private String name; @OneToMany(cascade=CascadeType.ALL) @PrivateOwned private List<Property> properties = new ArrayList<Property>(); ... // getter and setter following here } public class Property implements Serializable { @Id @GeneratedValue(strategy = GenerationType.TABLE) private int id; @OneToOne private Item item; private String value; ... // getter and setter following here } public class Item implements Serializable { @Id @GeneratedValue(strategy = GenerationType.TABLE) private int id; private String name; .... // getter and setter following here } // Code end In the table view the y-axis is more or less created with the query Query q = em.createQuery("SELECT m FROM Thing m ORDER BY m.name ASC"); using the "name" attribute from the Thing objects as label. In the table view the x-axis is more or less created with the query Query q = em.createQuery("SELECT m FROM Item m ORDER BY m.name ASC"); using the "name" attribute from the Item objects as label. Each cell has the value Things.getProperties().get[x].getValue() Unfortunately the list "properties" is not ordered, so the combination of cell value and x-axis column number (x) is not necessarily correct. Therefore I need to order the list "properties" in the same way as I ordered the labeling of the x-axis. And exactly this is the thing I dont know how it is done. So querying for the Thing objects should return the list "properties" "ORDER BY name ASC" but of the "Item"s objects. My ideas are something like having a query with two JOINs. Joing Things with Property and with Item but somehow I was unable to get it to work yet. Thank you for your help and your ideas to solve this riddle.

  • Use HttpGet with illegal characters in the URL

    - by kaciula
    I am trying to use DefaultHttpClient and HttpGet to make a request to a web service. Unfortunately the web service URL contains illegal characters such as { (ex: domain.com/service/{username}). It's obvious that the web service naming isn't well written but I can't change it. When I do HttpGet(url), I get that I have an illegal character in the url (that is { and }). If I encode the URL before that, there is no error but the request goes to a different URL where there is nothing. The url, although has illegal characters, works from the browser but the HttpGet implementation doesn't let me use it. What should I do or use instead to avoid this problem?

  • J2ME Development: Netbeans vs Eclipse

    - by Andrea Zilio
    I have to develop a J2ME application that will take advantage of Bluetooth technology to communicate with other instances of itself on other mobile devices. I know that both NetBeans and Eclipse offer an integrated environment to develop J2ME applications. Which one is more mature and stable? Which one offers better tools? My application has to communicate to many more devices running the same app and so I need to test my application with multiple instances of emulators running it and allowing these emulator instances to see each other via the J2ME Bluetooth APIs. Will I be able to do this?

  • Collection.contains(Enum.Value) in HQL?

    - by Seth
    I'm a little confused about how to do something in HQL. So let's say I have a class Foo that I'm persisting in hibernate. It contains a set of enum values, like so: public class Foo { @CollectionOfElements private Set<Bar> barSet = new HashSet<Bar>(); //getters and setters here ... } and public enum Bar { A, B } Is there an HQL statement I can use to fetch only Foo instances who'se barSet containst Bar.B? List foos = session.createQuery("from Foo as foo " + "where foo.barSet.contains.Bar.B").list(); Or am I stuck fetching all Foo instances and filtering them out at the DAO level? List foos = session.createQuery("from Foo as foo").list(); List results = new ArrayList(); for(Foo f : foos) { if(f.barSet.contains(Bar.B)) results.add(f); } Thanks!

  • HttpURLConnection: What is the minimum best-practice implementation?

    - by stormin986
    I've come across a lot of HttpURLConnection examples that are nothing more than openConnection(), getInputStream(), and then they just read the buffer and are done. It's simple but seems like it's not the best implementation ... it handles no problems. I don't yet know much about http, so I keep thinking I have everything covered until a new problem arises. I'm currently experiencing a similar problem to this one. Most times I try to read the same resource a second time (from a different HttpURLConnection object, after I .disconnect()'ed the previous one), the response code returns as -1 (but no exception is thrown!!). Before I knew to check the response code, I was baffled since I was throwing no exceptions. So, is there a minimum 'best practice' HttpURLConnection implementation? What are notable exceptions to handle? Request code checking? Any other error checks? What connection parameters do and don't need to be set (like doInput / doOutput, are these even necessary? Some examples have em, some don't). Etc. I realize this is kind of a broad question but I think it has potential to be a very useful resource if many of the common use cases and FAQs are addressed in one central place. This seems like the kind of thing a community wiki would be good for...

  • Simple Xml list parsing problem

    - by Hubidubi
    I have this xml: <root> <fruitlist> <apple>4</apple> <apple>5</apple> <orange>2</orange> <orange>6</orange> </fruitlist> </root> I'm writing a parser class, although I can't figure out how to deal with multiple node types. I can easily parse a list that contains only one node type (eg. just apples, not oranges) @ElementList(name = "fruitlist") private List<Apple> exercises; with more than one node type it also wants so parse non Apple nodes which doesn't work. I also tried to make another list for oranges, but it doen't work, I can't use fruitlist name more than once. @ElementList(name = "fruitlist", entry = "orange") private List<Orange> exercises; The ideal would be two seperate list for both node types. Hubi EDIT: After more searching & fiddling this question is a duplicate: Inheritance with Simple XML Framework

  • Unable to use JConsole with Tomcat running as windows service

    - by Kees de Kooter
    I am running tomcat 6.0.18 as a windows service. In the service applet the jvm is configured default, i.e. it is using jvm.dll of the JRE. I am trying to monitor this application with JConsole but cannot connect to it locally. I added the parameter -Dcom.sun.management.jmxremote (which works when starting tomcat with the start.bat script). But the jvm does not seem to pick up the parameter.
