  • hibernate show real sql

    - by tommaso
    Hi all, if I set <property name="show_sql">true</property> in my hibernate.cfg.xml configuration file in the console I can see the sql. But it's not REAL sql... Can I see the SQL code that will be passed directly to database? Example: I see select this_.code from true.employee this_ where this_.code=? Can I see select employee.code from employee where employee.code=12 the real sql? thanks!

  • CORBA Naming Service returns incorrect location of a registered object

    - by dave-keiture
    Hi experts, I have a simple setup with several objects registered at orbd. Remote client initializes connection to the ORB and tries to resolve a reference to the Naming Serice (IDL:omg.org/CosNaming/NamingContextExt:1.0). So far it's all fine - ORB returns giop.iiop.host/giop.iiop.port pair. When reference to the Naming Service is resolved, client tries to resolve_str() one of the registered objects. This time, Naming Service returns completely different pair giop.iiop.host/giop.iiop.port for the object (not the host/port of a Naming Service) - I don't know anything about them. When client tries to call a method on a resolved object, it fails, as the host/port pair is not configured in the firewall. Could you please explain, why it's happening? Thanks in advance!

  • OpenCMS - Best approach for showing rotating references

    - by user197127
    Hi, I would like to add on the right column of my site a rotating references section. Each reference would have some text + name of person + company name. It does not need to be structured (open text is also ok). I would then want opencms to rotate between 20 difference references each time a page is displayed. I can keep a session scope counter holding which reference we last showed. I need a way to manage the references (users not programmers) over time. My question is which would be the best way to do so? Thanks

  • How to store some of the entity's values in another table using hibernate?

    - by nimcap
    Hi guys, is there a simple way to persist some of the fields in another class and table using hibernate. For example, I have a Person class with name, surname, email, address1, address2, city, country fields. I want my classes to be: public class Person { private String name; private String surname; private String email; private Address address; // .. } public class Address { private Person person; // to whom this belongs private String address1; private String address2; private String city; private Address country; // .. } and I want to store Address in another table. What is the best way to achieve this? Edit: I am using annotations. It does not have to be the way I described, I am looking for best practices. PS. If there is a way to make Address immutable (to use as a value object) that is even better, or maybe not because I thought everything from wrong perspective :)

  • Regex take too long to match the result

    - by Joe Ijam
    Hi all I have this regex pattern <(\d+)>(\d+\.\d+|\d{4}\-\d+\-\d+\s+\d{2}:\d{2}:\d{2})(?:\..*?)*\s+(ALER|NOTI) and this is my input (will not matched at all) <150>2010-12-29 18:11:30.883 -0700 192.168.2.145 80 192.168.2.87 2795 "-" "-" GET HTTP 192.168.2.145 HTTP/1.1 200 36200 0 1038 544 192.168.2.221 80 540 SERVER DEFAULT PASSIVE VALID /joomla/ "-" http://192.168.2.145/joomla/index.php?option=com_content&view=a be4d44e8f3986183a87991398c1c212e=1; be4d44e8f3986183a87991398c1c212e=1 This will return not matched result but it takes too long to output the result. Since i have a thousand of logs/inputs in a second, it should finish very fast for every single log/input. Sometime it reaches CPU 100%. Can anyone help me to solve this regex problem? Thanks

  • How to replace a regexp group with a post proceed value?

    - by Pentium10
    I have this code to public static String ProcessTemplateInput(String input, int count) { Pattern pattern = Pattern.compile("\\{([^\\}]+)\\}"); Matcher matcher = pattern.matcher(input); while (matcher.find()) { String newelem=SelectRandomFromTemplate(matcher.group(1), count); } return input; } Input is: String s1 = "planets {Sun|Mercury|Venus|Earth|Mars|Jupiter|Saturn|Uranus|Neptune}{?|!|.} Is this ok?

  • How do I prevent JAXB from binding superclass methods of the @XmlRootElement when marshalling?

    - by Matt Fisher
    I have a class that is annotated as the @XmlRootElement with @XmlAccessorType(XmlAccessType.NONE). The problem that I am having is that the superclass's methods are being bound, when I do not want them to be bound, and cannot update the class. I am hoping there is an annotation that I can put on the root element class to prevent this from happening. Example: @XmlRootElement @XmlAccessorType(XmlAccessType.NONE) public class Person extends NamedObject { @XmlElement public String getId() { ... } } I would expect that only the methods annotated @XmlElement on Person would be bound and marshalled, but the superclass's methods are all being bound, as well. The resulting XML then has too much information. How do I prevent the superclass's methods from being bound without having to annotate the superclass, itself?

  • Junit Parameterized tests together with Powermock - how!?

    - by Subtwo
    Hi! I've been trying to figure out how to run parameterized tests in Junit4 together with PowerMock. The problem is that to use PowerMock you need to decorate your test class with @RunWith(PowerMock.class) and to use parameterized tests you have to decorate with @RunWith(Parameterized.class) From what I can see they seem mutually excluded!? Is this true? Is there any way around this? I've tried to create a parameterized class within a class running with PowerMock; something like this: @RunWith(PowerMock.class) class MyTestClass { @RunWith(Parameterized.class) class ParamTestClass { // Yadayada } } But unfortunately this doesn't do much good... The ParamTestClass still doesn't run with PowerMock support (not that surprisingly maybe)... And I've kind of run out of ideas so any help is greatly appreciated!

  • Android app works on emulator but not on phone ("Can't dispatch DDM chunk XXXX: no handler defined")

    - by JR_vv2
    Hey all, I made a very simple application to start playing around with Android development. It works fine on the emulator, but it gives me the following error when I try to install it on my HTC Hero (v1.5): Sorry! The application Simple Dial (process com.foo.simpledial) has stopped unexpectedly. Please try again. (Force Close button) and on in the Eclipse console, I get the following message: [2010-06-14 23:10:52 - Simple Dial] Uploading Simple Dial.apk onto device 'HT9BSHF00222' [2010-06-14 23:10:53 - Simple Dial] Installing Simple Dial.apk...

  • Using injected EntityManager in class hierarchies

    - by Emre Sahin
    The following code works: @Stateless @LocalBean public class MyClass { @PersistenceContext(name = "MyPU") EntityManager em; public void myBusinessMethod(MyEntity e) { em.persist(e); } } But the following hierarchy gives a TransactionRequiredException in Glassfish 3.0 (and standard JPA annotations with EclipseLink.) at the line of persist. @Stateless @LocalBean public class MyClass extends MyBaseClass { public void myBusinessMethod(MyEntity e) { super.update(e); } } public abstract class MyBaseClass { @PersistenceContext(name = "MyPU") EntityManager em; public void update(Object e) { em.persist(e); } } For my EJB's I collected common code in an abstract class for cleaner code. (update also saves who did the operation and when, all my entities implement an interface.) This problem is not fatal, I can simply copy update and sister methods to subclasses but I would like to keep all of them together in a single place. I didn't try but this may be because my base class is abstract, but I would like to learn a proper method for such a (IMHO common) use case.

  • 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?

  • do I need to close an audio Clip?

    - by Michael
    have an application that processes real-time data and is supposed to beep when a certain event occurs. The triggering event can occur multiple times per second, and if the beep is already playing when another event triggers the code is just supposed to ignore it (as opposed to interrupting the current beep and starting a new one). Here is the basic code: Clip clickClip public void prepareProcess() { super.prepareProcess(); clickClip = null; try { clipFile = new File("C:/WINDOWS/Media/CHIMES.wav"); ais = AudioSystem.getAudioInputStream(clipFile); clickClip = AudioSystem.getClip(); clickClip.open(ais); fileIsLoaded = true; } catch (Exception ex) { clickClip = null; fileIsLoaded = false; } } public void playSound() { if (fileIsLoaded) { if ((clickClip==null) || (!clickClip.isRunning())) { try { clickClip.setFramePosition(0); clickClip.start(); } catch (Exception ex) { System.out.println("Cannot play click noise"); ex.printStackTrace(); } } } The prepareProcess method gets run once in the beginning, and the playSound method is called every time a triggering event occurs. My question is: do I need to close the clickClip object? I know I could add an actionListener to monitor for a Stop event, but since the event occurs so frequently I'm worried the extra processing is going to slow down the real-time data collection. The code seems to run fine, but my worry is memory leaks. The code above is based on an example I found while searching the net, but the example used an actionListener to close the Clip specifically "to eliminate memory leaks that would occur when the stop method wasn't implemented". My program is intended to run for hours so any memory leaks I have will cause problems. I'll be honest: I have no idea how to verify whether or not I've got a problem. I'm using Netbeans, and running the memory profiler just gave me a huge list of things that I don't know how to read. This is supposed to be the simple part of the program, and I'm spending hours on it. Any help would be greatly appreciated! Michael

  • Best practice for storage and retrieval of error messages.

    - by ferrari fan
    What is a best practice for storing user messages in a configuration file and then retrieving them for certain events throughout an application? I was thinking of having 1 single configuration file with entries such as REQUIRED_FIELD = {0} is a required field INVALID_FORMAT = The format for {0} is {1} etc. and then calling them from a class that would be something like this public class UIMessages { public static final String REQUIRED_FIELD = "REQUIRED_FIELD"; public static final String INVALID_FORMAT = "INVALID_FORMAT"; static { // load configuration file into a "Properties" object } public static String getMessage(String messageKey) { // return properties.getProperty(messageKey); } } Is this the right way to approach this problem or is there some de-facto standard already in place?

  • Multi Process Configuration

    - by user200937
    Hi, I have a product built out of multiple processes. Each process uses internally commons configuration. Does anyone have an idea how to manage the config? I.e. we do not want to duplicate variables so each process will be able to read them. Additionally, DB solution is no good, as we do not want to be dependent on DB for something like configuration. Thanks Yair

  • Check if there are any repeated elements in a array recursively

    - by devoured elysium
    I have to find recursively if there is any repeated element in an integer array v. The method must have the following signature: boolean hasRepeatedElements(int[] v) I can't see any way of doing that recursively without having to define another method or at least another overload to this method (one that takes for example the element to go after or something). At first I thought about checking for the current v if there is some element equal to the first element, then creating a new array with L-1 elements etc but that seems rather inefficient. Is it the only way? Am I missing here something?

  • Axis webservice calls fail sometimes, access.log shows content!

    - by epischel
    Hi, our app is a webservice client (axis 1) to a third party webservice (also axis 1). We use it for some years now. Since a few weeks, we (as a client) get sometimes HTTP status 400 (bad request) or read timeouts when calling the webservice. Strangely, the access.log of the service shows part of the request or the response instead of the URL. It looks like this (looks like the end of the request string) x.x.x.x -> y.y.y.y:8080 - - [timestamp] "POST /webservice HTTP/1.0" 200 16127 0 x.x.x.x -> y.y.y.y:8080 - - [timestamp] "POST /webservice HTTP/1.0" 200 22511 1 x.x.x.x -> y.y.y.y:8080 - - [timestamp] "il=\"true\"/><nsl:text xsi:type=\"xsd:string\" xsi:nil=\"true\"/></SOAPSomeOperation></soapenv:Body></soapenv:Envelope> Axis/1.4" 400 299 0 or (some string out of the what looks like the request) x.x.x.x -> y.y.y.y:8080 - - [timestamp] ":string\">some text</sometag><othertag>moretext" 400 299 0 or in some other cases it looks like two requests thrown together (... means xml string left out): x.x.x.x -> y.y.y.y:8080 - - [timestamp] "...</someop></soapenv:Body></soapenv:Envelope>:xsd=\"http://www.w3.org/2001/XMLSchema\"...</soapenv:Body></soapenv:Envelope>" 400 299 0 Application log does not give any hints. Frequency of such call is 1% of all calls to that service. The only discriminator I know of so far is that it happens since operations informed us that the service url changed because of "server migration". Has anyone experienced such phenomenon yet? Has somebody got an idea whats wrong and how to fix? Thanks,

  • String Manipulation: Splitting Delimitted Data

    - by Milli Szabo
    I need to split some info from a asterisk delimitted data. Data Format: NAME*ADRESS LINE1*ADDRESS LINE2 Rules: 1. Name should be always present 2. Address Line 1 and 2 might not be 3. There should be always three asterisks. Samples: MR JONES A ORTEGA*ADDRESS 1*ADDRESS2* Name: MR JONES A ORTEGA Address Line1: ADDRESS 1 Address Line2: ADDRESS 2 A PAUL*ADDR1** Name: A PAUL Address Line1: ADDR1 Address Line2: Not Given My algo is: 1. Iterate through the characters in the line 2. Store all chars in a temp variables until first * is found. Reject the data if no char is found before first occurence of asterisk. If some chars found, use it as the name. 3. Same as step 2 for finding address line 1 and 2 except that this won't reject the data if no char is found My algo looks ugly. The code looks uglier. Spliting using //* doesn't work either since name can be replaced with address line 1 if the data was *Address 1*Address2. Any suggestion?
