  • netbeans custom jax-ws stubs..

    - by Sam
    Hi, I am using netbeans 6.9. I have made a JAX-WS service that returns a complex type, I have also made a JAX-WS client to consume it. The JAX-WS system automaticly creates a class for the client, inferred from the WSDl spec. I want to make my own class for this using JAXB annotations, so that I can add some extra functions to it. How do I go about replacing the autogenerated file with my own one? Could I also use the same class in the service to control how it is transmitted? Thanks!

  • Correct use of Classloader (especially in Android)

    - by Sebi
    I read some documentations about classloaders, but im still not sure where and why they are needed. The Android API says: Loads classes and resources from a repository. One or more class loaders are installed at runtime. These are consulted whenever the runtime system needs a specific class that is not yet available in-memory. So if i understand this correct, there can be many classlaoders which are responsible for loading new classes. But how the system decides which to use? And in which situation should a developer instantiate a new classloader? In the Android API for Intent there is a method public void setExtrasClassLoader (ClassLoader loader) The description says: Sets the ClassLoader that will be used when unmarshalling any Parcelable values from the extras of this Intent. So can i define there a special classloader so that i can pass object with an Intent which are not defined in the receiving activity? An example: If activity A which is located in Project A (in Eclipse) defines an object which i want to send to Activity B in Project B using putExtra of the Intent object. If this object which is send over the Intent is not defined (source code in project B), then there is a NoClassDefFoundException. So can i use the method setExtraClassloader to avoid this exception? If yes, how can i decide which classloader object i have to pass? And how do I instantiate it correctly?

  • Correct way to persist Quartz triggers

    - by davioooh
    I'm quite new to Quartz and now I need to schedule some jobs in Spring Web App. I know about Spring + Quartz integration (I'm using Spring v 3.1.1) but I'm wondering if it's the right way to follow. In particular I need to persist my scheduled tasks in a DB so I can re-initialize them when application is restarted. Are there some utilities provided by Spring scheduling wrapper to do this? Can you suggest me some "well known" approach to follow?

  • What is jasper report's algorithm for using a data source?

    - by spderosso
    Hi, I have created my custom data source by implementing the interface JRDataSource. This interface looks like this: public interface JRDataSource { /** * Tries to position the cursor on the next element in the data source. * @return true if there is a next record, false otherwise * @throws JRException if any error occurs while trying to move to the next element */ public boolean next() throws JRException; /** * Gets the field value for the current position. * @return an object containing the field value. The object type must be the field object type. */ public Object getFieldValue(JRField jrField) throws JRException; } My question is the following: In what way does jasper report call this functions for obtaining the fields in the .jrxml. E.g: if( next() )){ call getFieldValue for every field present in the page header while( next() ){ call getFieldValue for every field present in detail part } call getFieldValue for every field present the footer } The previous is just an example, experimentally in fact I found out that it is actually not like that. So my question arised. Thanks!

  • Possible to split one JAX-WS service across multiple source files?

    - by Rob S.
    Hi everyone, Is it possible to split a web service in to multiple classes and still provide a single path to the web service? I know this isn't possible because of the duplicate url-pattern values. It sort of illustrates where we're wanting to go :) <endpoint name="OneBigService" implementation="SmallImpl1" url-pattern="/OneBigService"/> <endpoint name="OneBigService" implementation="SmallImpl2" url-pattern="/OneBigService"/> Basically, how do avoid having one monolithic @WebService class? Thanks! Rob

  • 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

  • Do you have examples of un-helpful/Obscure error messages

    - by Wiretap
    Yesterday I got this error The processing instruction target matching "[xX][mM][lL]" is not allowed when I investigated, it was caused by whitespace at the very start of my XML document. Not difficult to solve, but I was struck with how unhelpful that particular error message was to identifying the actual problem. So what other examples of obscure errors do people have, and are you willing to admit to some of your own making.

  • How do I write a analyzable thread dump format

    - by gamue
    I'm creating a global exception handling which collects some information before shutting down in some cases. One of this information is the current thread dump. i do this with following code: ManagementFactory.getThreadMXBean().dumpAllThreads(true, true); The problem is to write the information into a analyzable format for TDA. Is there a "simple" way to format the information instead of writing the format on my own?

  • Max Daily Budget exceeded and Billing Status "Changing Daily Budget"

    - by draftpik
    We've exceeded the Max Daily Budget for our app, but we can't increase the budget due to a serious flaw in Google's billing system. Google App Engine and Google Wallet do not have very capable support for multiple sign-in. As a result, I went to change the budget, but it used the wrong Google Wallet account (a different Google Account I was signed in as). I had to go back and try again, but now our GAE app shows the following status: Billing Status: Changing Daily Budget Your account has been locked while we process your budget changes. If you were redirected to Google Checkout but did not complete the process, your settings will remain unchanged. (You will be able to make changes to your budget settings again once the outstanding payment is processed.) Now I'm completely prevented from making any billing changes, our app is shut off (over quota), and I have NOTHING I can do to fix it. This is a seriously fundamental flaw in App Engine's billing system and Google Wallet integration. Has anyone run into this before? Is there a workaround anyone is aware of? Right now, our production app is completely down thanks to this issue. Any help you can offer would be greatly appreciated? If you're from Google and you might be able to help on the backend, our app id is "nhldraftpik". Thanks! Brian

  • The system cannot find the path specified with FileWriter

    - by Nazgulled
    Hi, I have this code: private static void saveMetricsToCSV(String fileName, double[] metrics) { try { FileWriter fWriter = new FileWriter( System.getProperty("user.dir") + "\\output\\" + fileTimestamp + "_" + fileDBSize + "-" + fileName + ".csv" ); BufferedWriter csvFile = new BufferedWriter(fWriter); for(int i = 0; i < 4; i++) { for(int j = 0; j < 5; j++) { csvFile.write(String.format("%,10f;", metrics[i+j])); } csvFile.write(System.getProperty("line.separator")); } csvFile.close(); } catch(IOException e) { System.out.println(e.getMessage()); } } But I get this error: C:\Users\Nazgulled\Documents\Workspace\Só Amigos\output\1274715228419_5000-List-ImportDatabase.csv (The system cannot find the path specified) Any idea why? I'm using NetBeans on Windows 7 if it matters...

  • How would you code a washing machine?

    - by Dan
    Imagine I have a class that represents a simple washing machine. It can perform following operations in the following order: turn on - wash - centrifuge - turn off. I see two basic alternatives: A) I can have a class WashingMachine with methods turnOn(), wash(int minutes), centrifuge(int revs), turnOff(). The problem with this is that the interface says nothing about the correct order of operations. I can at best throw InvalidOprationException if the client tries to centrifuge before machine was turned on. B) I can let the class itself take care of correct transitions and have the single method nextOperation(). The problem with this on the other hand, is that the semantics is poor. Client will not know what will happen when he calls the nextOperation(). Imagine you implement the centrifuge button’s click event so it calls nextOperation(). User presses the centrifuge button after machine was turned on and ups! machine starts to wash. I will probably need a few properties on my class to parameterize operations, or maybe a separate Program class with washLength and centrifugeRevs fields, but that is not really the problem. Which alternative is better? Or maybe there are some other, better alternatives that I missed to describe?

  • 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?

  • Netbeans 7.2 won't open on OS X

    - by Mark van Wyk
    I installed Netbeans on OSX Mountain Lion running JDK 7. Everything was working fine. Then my machine for no reason crashed. After this I could no longer open Netbeans anymore. If I try to start Netbeans from the commandline: /Applications/NetBeans/NetBeans 7.2.app/Contents/MacOS/netbeans Then it works fine. From there I can select Netbeans About and confirm that my userdir and cachedir is: User directory: /Users/<user>/Library/Application Support/NetBeans/7.2 Cache directory: /Users/<user>/Library/Caches/NetBeans/7.2 So, I deleted these directories and tried again, but alas, I can only start netbeans via the commandline. Ideas appreciated...

  • Logging a specific package in log4j programmatically

    - by VinTem
    Hi there, here is the thing, I have to deploy a web app and the the log4j.properties file is created by the client so I dont have control over it. Their properties file is like this: log4j.rootCategory= FILE !-----------FILE--------------! log4j.category.FILE=DEBUG log4j.appender.FILE=org.apache.log4j.RollingFileAppender log4j.appender.FILE.File=${catalina.base}/logs/rcweb.log log4j.appender.FILE.MaxFileSize=1024KB log4j.appender.FILE.MaxBackupIndex=10 log4j.appender.FILE.layout=org.apache.log4j.PatternLayout log4j.appender.FILE.layout.ConversionPattern=%-2d{dd/MM/yyyy HH:mm:ss} [%t] %5p %c:%L - %m%n And in my classes I do something like this: private static final Logger LOG = Logger.getLogger(MaterialController.class); LOG.info("my log"); But the log file has never been created. I did the test and changed the log4j.properties file and deployed in my computer adding the following line: log4j.logger.br.com.golive.requisicaoCompras=DEBUG This works, but I cant use the file like this. Is there any ideas? Thanks

  • How to include NetBeans Platform Source code into module dependencies

    - by Ben Hammond
    I am debugging a NetBeans Platform application. I have downloaded the NetBeans Platform source code .zip file. I would really really like to attach the source code to the debugger so that I can seamlessly jump to internal NB source code. Normally I would edit the Library configuration to tell NB where to find the source code, and it would just work. However this is not possible for NetBeans Modules; when I look at the Utilities API module dependency it does not look like a normal NB library and there is nowhere to add in the source code. I suspect that if I were to rebuild my project using Maven this would work automatically. But thats a terrible reason to switch to maven. How can I get the NB Platform Source code included into my Module Dependencies ?
