  • 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

  • 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

  • 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?

  • 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.

  • does anyone see any issues with this thread pattern?

    - by prmatta
    Here is a simple thread pattern that I use when writing a class that needs just one thread, and needs to a specific task. The usual requirements for such a class are that it should be startable, stopable and restartable. Does anyone see any issues with this pattern that I use? public class MyThread implements Runnable { private boolean _exit = false; private Thread _thread = null; public void start () { if (_thread == null) { _thread = new Thread(this, "MyThread"); _thread.start(); } } public void run () { while (_exit) { //do something } } public void stop () { _exit = true; if (_thread != null) { _thread.interrupt(); _thread = null; } } } I am looking for comments around if I am missing something, or if there is a better way to write this.

  • How do I ensure my abstract class's function can only operate on extenders of the same type as the c

    - by incrediman
    For example, let's say this is my abstract class: abstract class A{ int x; int y; void foo(A fooMe); } ...and B and C are two classes which extend A. What I want is for B to only be able to call foo() on other Bs, and for C to only be able to call foo() on other Cs. But I want this to be out of the hands of the programmer who's extending my A class - that is, I want a way to ensure this functionality within As code alone. What can I do? (If possible) I'd like to avoid any hack or generics solution that's too messy - I still want foo to be able to be called like this, for example: B b=new B(); B bb=new B(); bb.foo(b);

  • LRU LinkedHashMap that limits size based on available memory

    - by sanity
    I want to create a LinkedHashMap which will limit its size based on available memory (ie. when freeMemory + (maxMemory - allocatedMemory) gets below a certain threshold). This will be used as a form of cache, probably using "least recently used" as a caching strategy. My concern though is that allocatedMemory also includes (I assume) un-garbage collected data, and thus will over-estimate the amount of used memory. I'm concerned about the unintended consequences this might have. For example, the LinkedHashMap may keep deleting items because it thinks there isn't enough free memory, but the free memory doesn't increase because these deleted items aren't being garbage collected immediately. Does anyone have any experience with this type of thing? Is my concern warranted? If so, can anyone suggest a good approach? I should add that I also want to be able to "lock" the cache, basically saying "ok, from now on don't delete anything because of memory usage issues".

  • How do I check that an entity is unreferenced in JPA?

    - by Martin
    I have the following model @Entity class Element { @Id int id; @Version int version; @ManyToOne Type type; } @Entity class Type { @Id int id; @Version int version; @OneToMany(mappedBy="type") Collection<Element> elements; @Basic(optional=false) boolean disabled; } and would like to allow Type.disabled = true only if Type.elements is empty. Is there a way to do it atomically? I would like to prevent an insertion of an Element in a transaction while the corresponding Type is being disabled by an other transaction.

  • Specifiy classpath for maven

    - by Zombies
    Quite new to maven here so let me explain first what I am trying to do: We have certain JAR files which will not be added to the repo. This is because they are specific to Oracle ADF and are already placed on our application server. There is only 1 version to be used for all apps at anyone time. In order to compile though, we need to have these on the class path. There are a LOT of these JARS, so if we were to upgrade to a newer version of ADF, we would have to go into every application and redefine some pretty redundant dependencies. So again, my goal is to just add these JARs to the classpath, since we will control what version is actually used elsewhere. So basically, I want to just add every JAR in a given directory to maven's classpath for when it compiles. And without putting any of these JAR files in a repository. And of course, these JARs are not to be packaged into any EAR/WAR.

  • Commons VFS and IBM MVS System

    - by Liming
    Hello All, I'm using Apache Commons VFS / SFTP, we are trying to download files from the IBM MVS system. The download part is all good, however, we can not open up the zipped files after downloading. Seems like the zip file was compressed using a different algorithm or something Anyone has any pointers? *Note, the same function works fine if we connect to a regular unix/linux SFTP server. Below is an example of what we did String defaultHost = "[my sftp ip address]"; String host = defaultHost; String defaultRemotePath = "//__root.dir1.dir2."; String remotePath = defaultRemotePath; String user = "test"; String password = "test"; String remoteFileName = "Blah.ZIP.BLAH"; log.info("FtpPojo() begin instantiation"); FileObject localFileObject = fsManager.resolveFile("C:/Work/Blah.ZIP.BLAH"); log.debug("local file name is :"+localFileObject.getName().getBaseName()); log.debug("FtpPojo() instantiated and fsManager created"); String uri = createSftpUri(host, user, password) + ":322"+remotePath+remoteFileName; remoteRepo = fsManager.resolveFile(uri, fsOptions); remoteRepo.copyFrom(localFileObject, Selectors.SELECT_ALL);

  • Thread help with Android game

    - by Ciph3rzer0
    I need some help dealing with three Threads in Android One thread is the main thread, the other is the GLThread, and the other is a WorkerThread I created to update the game state. The problem I have is they all need to access the same LinkedList of game objects. Both the GLThread and my WorkerThread only read from the LinkedList, so no problem there, but occasionally I have the main thread adding in another game object to the list. How can I manage this? I tried using synchronized in front of the functions involved but it really slows down the application. For some reason, just catching the errors and not rendering or updating the game state that frame, causes it to start lagging permanently. Anyone have any great ideas?

  • 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?
