  • Error using maven profiles

    - by user3127896
    I've added two profiles to my application and that how it looks: <profiles> <profile> <id>dev</id> <properties> <db.username>root</db.username> <db.password>root</db.password> <db.connectionURL>localhost:3306</db.connectionURL> <db.driverClass>com.mysql.jdbc.Driver</db.driverClass> </properties> </profile> <profile> <id>prod</id> <properties> <db.username>prodroot</db.username> <db.password>prodpass</db.password> <db.connectionURL>localhost:3306</db.connectionURL> <db.driverClass>com.mysql.jdbc.Driver</db.driverClass> </properties> </profile> </profiles> In my jdbc.properties file i changed values like this: jdbc.driverClassName=${db.driverClass} jdbc.dialect=org.hibernate.dialect.MySQLDialect jdbc.databaseurl=jdbc:mysql://${db.connectionURL}/dbname jdbc.username=${db.username} jdbc.password=${db.password} And here's bean from spring-container.xml <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close" p:driverClassName="${jdbc.driverClassName}" p:url="${jdbc.databaseurl}" p:username="${jdbc.username}" p:password="${jdbc.password}" /> When i try to deploy my application i got following error: SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener org.springframework.beans.factory.BeanDefinitionStoreException: Invalid bean definition with name 'dataSource' defined in ServletContext resource [/WEB-INF/spring-servlet.xml]: Could not resolve placeholder 'db.driverClass' Structure of project: Any ideas what i'm doing wrong?

  • Can't access a property with <html:checkbox property="..."> when iterating a list

    - by Bernhard V
    Hi. In my Struts form I've got a list. In a JSP I iterate over it like this: <c:forEach items="${MyForm.auspraegungen}" var="auspraegung"> <tr> <td>${auspraegung.name}</td> <td>${auspraegung.forced}</td> <td>${auspraegung.cbx_uebernehmen}</td> <html:checkbox property="auspraegung.cbx_uebernehmen" /> </tr> </c:forEach> Now the <html:checkbox isn't working. I'm always getting the following error: Caused by: javax.servlet.jsp.JspException: No getter method for property auspraegung.cbx_uebernehmen of bean org.apache.struts.taglib.html.BEAN But actually there is a getter for this property in my form class. It's written like this: public Boolean getCbx_uebernehmen() { return cbx_uebernehmen; } When I remove the checkbox it's also possible to display the property as in the <td>-tag above so I don't know where the problem is. Maybe I'm accessing it in the wrong way?

  • How do I change the number of thumbnails seen in the Android sample Home application?

    - by Todd
    I am working with the sample Home application project on http://developer.android.com/resources/samples/Home/index.html I've added another value to the THUMBS_IDS and IMAGE_IDS Integer arrays in the Wallpaper class for a total of four wallpaper options. When I run the application with Device API version 7, Skin: HVGA, hw.lcd.density: 160, in portrait layout, the fourth wallpaper option is not shown. I need to use the directional keys in the emulator to see the 4th wallpaper option, because the first option is centered. I have modified only the wallpaper.xml file with a variety of android:layout_* options with no success at this point. How do I show all four of my wallpaper options?

  • After a few same hql query the application freezes

    - by Oktay
    I am calling below function with the same batchNumber and it is working without problem 15 times and takes the records fromm database without problem but at 16. time the application freezes when the query.list() row is called. It just loses debug focus and not give any exception. This problem probably is not about the hql because I've seen this problem before and I used criteria instead of hql and I got pass this problem. But for this when I use "group by" in criteria(setrojection....) it doesn't return the result as hibernate model(object) just returns a list. But I need the results as model. Note: about 15 times it is just for test. This is a web aplication and user may click the button many times that calls this funtion to see the taken records from database. public List<SiteAddressModel> getSitesByBatch(String batchNumber) { try{ List<SiteAddressModel> siteList; MigrationPlanDao migrationPlanDao = ServiceFactory.getO2SiteService().getMigrationPlanDao(); Query query = this.getSession().createQuery("from " + persistentClass.getName() + " where " + "siteType =:" + "type and siteName in " + "(select distinct exchange from " + migrationPlanDao.getPersistentClass().getName() + " where migrationBatchNumber =:" + "batchNumber" + ")" ); query.setString("batchNumber", batchNumber); query.setString("type", "LLU/ASN"); System.out.println("before query"); siteList = query.list(); System.out.println("after query"); return siteList; }catch (Exception e) { e.printStackTrace(); } Hibernate version 3.2.0.ga

  • Merge object from list by comparing one value

    - by Bala
    I have two List of Objects (one is master list and other is error list) and if there is a match of one value when compared two lists then merge all other error list values into mast list value (only one object). Other than iterating is there any other way to compare a value and then merge that object. Object is a Value object with some setters and getters. Appreciate your help. List<OrderVO> masterList; List<OrderVO> errorList; If errorList.OrderVO.getOrderID = masterList.OrderVO.getOrderID then masterList.OrderVO.merge(errorList.OrderVO) or copy all values of masterList.OrderVO.copy(errorList.OrderVO). Hoper this is clear

  • Polymorphic behavior not being implemented

    - by Garrett A. Hughes
    The last two lines of this code illustrate the problem: the compiler works when I use the reference to the object, but not when I assign the reference to an array element. The rest of the code is in the same package in separate files. BioStudent and ChemStudent are separate classes, as well as Student. package pkgPoly; public class Poly { public static void main(String[] arg) { Student[] stud = new Student[3]; // create a biology student BioStudent s1 = new BioStudent("Tom"); // create a chemistry student ChemStudent s2 = new ChemStudent("Dick"); // fill the student body with studs stud[0] = s0; stud[1] = s1; // compiler complains that it can't find symbol getMajor on next line System.out.println("major: " + stud[0].getMajor() ); // doesn't compile; System.out.println("major: " + s0.getMajor() ); // works: compiles and runs correctly } }

  • Getting Frequency Components with FFT

    - by ruhig brauner
    so I was able to solv my last problem but i stubmled upon the next already. So I want to make a simple spectrogram but in oder to do so I want to understand how FFT-libaries work and what they actually calculate and return. (FFT and Signal Processing is the number 1 topic I will get into as soon as I have time but right now, I only have time for some programming exercises in the evening. ;) ) Here I just summarized the most important parts: int framesPerSecond; int samplesPerSecond; int samplesPerCycle; // right now i want to refresh the spectogram every DoubleFFT_1D fft; WAVReader audioIn; double audioL[], audioR[]; double fftL[], fftR[]; ..... framesPerSecond = 30; audioIn= new WAVReader("Strobe.wav"); int samplesPerSecond = (int)audioIn.GetSampleRate(); samplesPerCycle = (int)(audioIn.GetSampleRate()/framesPerSecond); audioL = new double[samplesPerCycle*2]; audioR = new double[samplesPerCycle*2]; fftL = new double[samplesPerCycle]; fftR = new double[samplesPerCycle]; for(int i = 0; i < samplesPerCycle; i++) { // don't even know why,... fftL[i] = 0; fftR[i] = 0; } fft = new DoubleFFT_1D(samplesPerCycle); ..... for(int i = 0; i < samplesPerCycle; i++) { audioIn.GetStereoSamples(temp); audioL[i]=temp[0]; audioR[i]=temp[1]; } fft.realForwardFull(audioL); //still stereo fft.realForwardFull(audioR); System.out.println("Check"); for(int i = 0; i < samplesPerCycle; i++) { //storing the magnitude in the fftL/R arrays fftL[i] = Math.sqrt(audioL[2*i]*audioL[2*i] + audioL[2*i+1]*audioL[2*i+1]); fftR[i] = Math.sqrt(audioR[2*i]*audioR[2*i] + audioR[2*i+1]*audioR[2*i+1]); } So the question is, if I want to know, what frequencys are in the sampled signal, how do I calculate them? (When I want to print the fftL / fftR arrays, I get some exponential formes at both ends of the array.) Thx :)

  • Not reaction to pressing button

    I have a ring in primefaces: <h:form> <p:ring id="ring" value="#{ringBean.images}" var="image" styleClass="image-ring" easing="easeInOutBack"> <p:graphicImage value="./../../images/#{image.image}" width="150" height="150"/> <p:commandButton value="#{image.name}" action="#{image.action}" /> </p:ring> </h:form> My RingBean: @ManagedBean @RequestScoped public class RingBean implements Serializable{ private List<PersonImage> images; private PersonImage selectedPerson; public RingBean() { images = new ArrayList<PersonImage>(); images.add(new PersonImage("person3.png", "Pacjent", "patientList")); images.add(new PersonImage("person4.png", "Admin", "adminList")); images.add(new PersonImage("person5.png", "Lekarz", "doctorList")); images.add(new PersonImage("person6.png", "Sekretarka", "secretaryList")); images.add(new PersonImage("person7.png", "Nieaktywni", "inactiveList")); } public List<PersonImage> getImages() { return images; } public PersonImage getSelectedPerson() { return selectedPerson; } public void setSelectedPerson(PersonImage selectedPerson) { this.selectedPerson = selectedPerson; } } PersonImage class: public class PersonImage { String image; String name; String action; public PersonImage() { } public PersonImage(String image, String name, String action) { this.image = image; this.name = name; this.action = action; } public String getImage() { return image; } public void setImage(String image) { this.image = image; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getAction() { return action; } public void setAction(String action) { this.action = action; } } faces-config: <navigation-case> <from-outcome>adminList</from-outcome> <to-view-id>/protected/admin/adminList.xhtml</to-view-id> <redirect/> </navigation-case> <navigation-case> <from-outcome>doctorList</from-outcome> <to-view-id>/protected/admin/doctorList.xhtml</to-view-id> <redirect/> </navigation-case> <navigation-case> <from-outcome>patientList</from-outcome> <to-view-id>/protected/admin/patientList.xhtml</to-view-id> <redirect/> </navigation-case> <navigation-case> <from-outcome>secretaryList</from-outcome> <to-view-id>/protected/admin/secretaryList.xhtml</to-view-id> <redirect/> </navigation-case> When i pressed my button, not reaction. Why? I added the action in button: And in Ring I add: images.add(new PersonImage("person4.png", "Admin", "adminList")); action is adminList. Why this not work? When i changed in button: <p:commandButton value="#{image.name}" action="adminList" /> all work. Why? Both construction returned identical string.

  • comma in regex in String.replaceAll() method?

    - by kknight
    My code tries to replace "," with "/" in a string. Should I escape "," in the regex string? Both of the two code snippets generated the same results, so I am confused. Code snippet 1: String test = "a,bc,def"; System.out.println(test.replaceAll("\\,", "/")); Code snippet 2: String test = "a,bc,def"; System.out.println(test.replaceAll(",", "/")); Should I use "," or "\,"? Which is safer? Thanks.

    - by user558019
    Dear All i have very strange problem we are using jpa 2.0 with hibernate and spring 3.0 mvc annotations based Database generated through JPA DDL is true and MySQL as Database; i will provide some refference classes and then my porblem. public abstract class Common implements serializable{ @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "id", updatable = false) private Long id; @ManyToOne @JoinColumn private Address address; //with all getter and setters //as well equal and hashCode } public class Parent extends Common{ private String name; @OneToMany(cascade = {CascadeType.MERGE,CascadeType.PERSIST}, mappedBy = "parent") private List<Child> child; //setters and rest of class } public class child extends Common{ //some properties with getter/setters } public class Address implements Serializable{ @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "id", updatable = false) private Long id; private String street; //rest of class with get/setter } as in code you can see that parents and child classes extends Common class so both have address property and id , the problem occurs when change the address refference in parent class it reflect same change in all child objects in list and if change address refference in child class then on merge it will change address refference of parent as well i am not able to figure out is it is problem of jpa or hibernate or spring thanks in advance

  • Handling a binary operation that makes sense only for part of a hierarchy.

    - by usersmarvin_
    I have a hierarchy, which I'll simplify greatly, of implementations of interface Value. Assume that I have two implementations, NumberValue, and StringValue. There is an average operation which only makes sense for NumberValue, with the signature NumberValue average(NumberValue numberValue){ ... } At some point after creating such variables and using them in various collections, I need to average a collection which I know is only of type NumberValue, there are three possible ways of doing this I think: Very complicated generic signatures which preserve the type info in compile time (what I'm doing now, and results in hard to maintain code) Moving the operation to the Value level, and: throwing an unsupportedOperationException for StringValue, and casting for NumberValue. Casting at the point where I know for sure that I have a NumberValue, using slightly less complicated generics to insure this. Does anybody have any better ideas, or a recommendation on oop best practices?

  • Junit test that creates other tests

    - by Benju
    Normally I would have one junit test that shows up in my integration server of choice as one test that passes or fails (in this case I use teamcity). What I need for this specific test is the ability to loop through a directory structure testing that our data files can all be parsed without throwing an exception. Because we have 30,000+ files that that 1-5 seconds each to parse this test will be run in its own suite. The problem is that I need a way to have one piece of code run as one junit test per file so that if 12 files out of 30,000 files fail I can see which 12 failed not just that one failed, threw a runtimeexception and stopped the test. I realize that this is not a true "unit" test way of doing things but this simulation is very important to make sure that our content providers are kept in check and do not check in invalid files. Any suggestions?

    I've an h:dataTable to display my item information (in my case a customer support request) and for each row I'd like to put an h:inputText and h:commandButton to add a comment to the desired item. I've no problem with action, but my question is about the correct way to manage many h:inputText and related value on backbean. I'm not sure that is correct to make all h:inputText set the value to the same backbean property. Any suggestions? Thanks all.

  • Volatile keyword

    - by Tiyoal
    Say I have two threads and an object. One thread assigns the object: public void assign(MyObject o) { myObject = o; } Another thread uses the object: public void use() { myObject.use(); } Does the variable myObject have to be declared as volatile? I am trying to understand when to use volatile and when not, and this is puzzling me. Is it possible that the second thread keeps a reference to an old object in its local memory cache? If not, why not? Thanks a lot.

  • Unable to use JAR in Eclipse

    Hi guys, I have just created my first JAR in Eclipse, just a simple program with a single class Database.class. It is not in a package. public class Database { public Database() { int dbInit = 1; } } I have added it as an external JAR to the build path libraries for another project in Eclipse, but for some reason I cannot get Database db = new Database(), the default constructor, to work - it's as if the contents of the JAR are not being recognised. Could anyone please offer any advice on this? Thanks very much, M
