  • Generics in custom configuration sections

    - by Jonn
    I tried making a custom configuration class that went on like this: WatcherServiceInfoSection<TWatcherServiceDetailElement> where TWatcherServiceDetailElement is a ConfigurationElement inside it. Now when I call the type in the ConfigSections area of AppConfig I get the error: An error occurred creating the configuration section handler for WatcherServiceInfo: Could not load type 'Library.Common.Utilities.ConfigurationHandler.WatcherServiceInfoSection<ASNDPService.Configuration.WatcherServiceDetailElement>' from assembly Is what I'm doing possible? Can I have generic types in the type attribute for a custom section element? EDIT Additionally, how about ConfigurationElementCollection objects? Like in the above example, how could I do a [ConfigurationProperty("WatcherServiceDetails", IsRequired = true, IsDefaultCollection = true)] [ConfigurationCollection(typeof(TWatcherServiceDetailElement), AddItemName = "WatcherServiceDetail")] public WatcherServiceDetailCollection<TWatcherServiceDetailElement> WatcherServiceDetails I'm aware that type parameters aren't allowed for attributes and that's what I want to know how to do.

  • Frequent occurence of FULL GC.

    - by Viji
    Hi, There is a frequent occurence of FULL GC in our system. We are using Java application running on Tomcat server. Our application is running using internal load balancer setup. We are seeing lot of Full GC's in the server logs due to which the application is hung and Proxy errors are occured. The Java parameter values we are using are: Webapp wrapper: wrapper.java.additional.4=-Xms382M wrapper.java.additional.5=-Xmx1024M Backapp wrapper: wrapper.java.additional.4=-Xms382M wrapper.java.additional.5=-Xmx1024M The error found in webapp wrapper logs: INFO | jvm 1 | 2010/11/26 09:33:19 | [PSYoungGen: 1398460K-140291K(1514624K)] 4623364K-3491394K(5009920K), 0.7285303 secs] [Times: user=1.42 sys=0.00, real=0.72 secs] INFO | jvm 1 | 2010/11/26 09:33:19 | 68539.126: [Full GC DEBUG | wrapperp | 2010/11/26 09:33:19 | send a packet PING : ping Tried to change the JVM values to increase the heap size. But of no use. I suspect that there could be some other reason other than these parameters which is causing the issue. Can anyone please help me on this?

  • Structuremap Configuration with generics

    - by DarthVader
    I have IRepository interface with which i want to use NHibernateRepository. How do i configure it with structure map? protected void ConfigureDependencies() { ObjectFactory.Initialize( x => { x.For<ILogger>().Use<Logger>(); x.For<IRepository<T>>().Use<NHibernateRepository<T>>(); } ); } I m getting an error on T. Another question I have is if it s OK to make an ApplicationContext static class, configure it with structure map and provide instances with it? I have read that static classes are bad, but I dont want to initialize the ApplicationContext class that I have the injections everywhere. What s the best practice for this? Thanks.

  • Difference between methods with and without generics

    - by isakavis
    Can someone help me understand advantages and disadvantages (if any) between the following methods which do the same function of storing away the entity to azure (in my case)? public bool Save<T>(string tableName, T entity) where T : TableEntityBase, new() { throw new NotImplementedException(); } vs public bool Save(string tableName, TableEntityBase entity) { throw new NotImplementedException(); }

  • JAX-WS MarshalException with custom JAX-B bindings: Unable to marshal type "java.lang.String" as an

    - by MoneyMark
    I seem to be having an issue with Jax-WS and Jax-b playing nicely together. I need to consume a web-service, which has a predefined WSDL. When executing the generated client I am receiving the following error: javax.xml.ws.WebServiceException: javax.xml.bind.MarshalException - with linked exception: [com.sun.istack.SAXException2: unable to marshal type "java.lang.String" as an element because it is missing an @XmlRootElement annotation] This started occurring when I used an external custom binding file to map needlessly complex types to java.lang.string. Here is an excerpt from my binding file: <?xml version="1.0" encoding="UTF-8"?> <bindings xmlns="http://java.sun.com/xml/ns/jaxb" version="2.0" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"> <bindings schemaLocation="http://localhost:7777/GESOR/services/RegistryUpdatePort?wsdl#types?schema1" node="/xs:schema"> <bindings node="//xs:element[@name='StwrdCompany']//xs:complexType//xs:sequence//xs:element[@name='company_name']"> <property> <baseType name="java.lang.String" /> </property> </bindings> <bindings node="//xs:element[@name='StwrdCompany']//xs:complexType//xs:sequence//xs:element[@name='address1']"> <property> <baseType name="java.lang.String" /> </property> </bindings> <bindings node="//xs:element[@name='StwrdCompany']//xs:complexType//xs:sequence//xs:element[@name='address2']"> <property> <baseType name="java.lang.String" /> </property> </bindings> ...more fields </bindings> </bindings> When executing wsimport against the provided WSDL, StwrdCompany is generated with the following variables declared: @XmlRootElement(name = "StwrdCompany") public class StwrdCompany { @XmlElementRef(name = "company_name", type = JAXBElement.class) protected String companyName; @XmlElementRef(name = "address1", type = JAXBElement.class) protected String address1; @XmlElementRef(name = "address2", type = JAXBElement.class) ... more fields ... getters/setters @XmlAccessorType(XmlAccessType.FIELD) @XmlType(name = "", propOrder = { "value" }) public static class CompanyName { @XmlValue protected String value; @XmlAttribute protected Boolean updateToNULL; /** * Gets the value of the value property. * * @return * possible object is * {@link String } * */ public String getValue() { return value; } /** * Sets the value of the value property. * * @param value * allowed object is * {@link String } * */ public void setValue(String value) { this.value = value; } /** * Gets the value of the updateToNULL property. * * @return * possible object is * {@link Boolean } * */ public boolean isUpdateToNULL() { if (updateToNULL == null) { return false; } else { return updateToNULL; } } /** * Sets the value of the updateToNULL property. * * @param value * allowed object is * {@link Boolean } * */ public void setUpdateToNULL(Boolean value) { this.updateToNULL = value; } ... more inner classes } } Finally, here is the associated snippet from the WSDL that seems to be causing such grief. <xs:element name="StwrdCompany"> <xs:complexType> <xs:sequence> <xs:element maxOccurs="1" minOccurs="0" name="company_name" nillable="true"> <xs:complexType> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute default="false" name="updateToNULL" type="xs:boolean"/> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:element> <xs:element maxOccurs="1" minOccurs="0" name="address1" nillable="true"> <xs:complexType> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute default="false" name="updateToNULL" type="xs:boolean"/> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:element> ... more fields in the same format <xs:element maxOccurs="1" minOccurs="0" name="p_source_timestamp" nillable="false" type="xs:string"/> </xs:sequence> <xs:attribute name="company_xid" type="xs:string"/> </xs:complexType> </xs:element> The reason for the custom binding is so I can map user input from a pojo into the StwrdCompany object more easily, whether it be direct instantiation or through the use of Dozer for bean mapping. I was unable to successfully map between the objects without the custom binding. Finally, one other thing I tried was setting a globalBinding definition: <globalBindings generateValueClass="false"></globalBindings> This caused the server to through an argument mismatch exception since the Soap Message was using xs:string xml types instead of passing the defined complex types, so I abandoned that idea. Any insight into what is causing the MarshalException or how to go about solving the issue of calling the webservice and mapping these objects more easily, is greatly appreciated. I've been searching for days and I sadly think I am stumped.

  • Android: Strange out of memory issue

    - by Chrispix
    I am not sure where to start to explain this one. I have a list view with a couple image buttons on each row. When you click the list row, it launches a new activity. If you review some of my other posts, I have had to build my own tabs because of an issue w/ the camera layout. The activity that gets launched for result is a map. If I click on my button to launch the image preview (load an image off the sd card) the application returns from the activity back to the listview activity to the result handler to relaunch my new activity which is nothing more than an image widget. So here is the issue, the image preview on the list view is being done w/ the cursor & listadapter. This makes it pretty simple, but I am not sure how I can put a resized (i.e. smaller bit size not pixel) image as the src for the imgbutton on the fly. So I just resized the image that came off the phone camera. The issue is that I get an out of memory error when it tries to go back and re-launch the 2nd activity. ** My question : is there a way I can build the list adapter easily row by row, where I can resize on the fly (bit wise)? - this would be preferable as I also need to make some changes to the properties of the widgets/elements in each row as I am unable to select a row w/ touch screen b/c of focus issue. (I can use roller ball). ** I know I can do an out of band resize and save of my image, but that is not really what I want to do, but some sample code for that would be nice if that is your suggestion. As soon as I disabled the image on the listview it worked fine again. FYI : This is how I was doing it : String[] from = new String[] { DBHelper.KEY_BUSINESSNAME, DBHelper.KEY_ADDRESS, DBHelper.KEY_CITY, DBHelper.KEY_GPSLONG, DBHelper.KEY_GPSLAT, DBHelper.KEY_IMAGEFILENAME + ""}; to = new int[] { R.id.businessname, R.id.address, R.id.city, R.id.gpslong, R.id.gpslat, R.id.imagefilename }; notes = new SimpleCursorAdapter(this, R.layout.notes_row, c, from, to); setListAdapter(notes); Where R.id.imagefilename is a ButtonImage Here is my LogCat 01-25 05:05:49.877: ERROR/dalvikvm-heap(3896): 6291456-byte external allocation too

  • Calling Grep inside Java gives incorrect results while calling grep in shell gives correct results.

    - by futureelite7
    I've got a problem where calling grep from inside java gives incorrect results, as compared to the results from calling grep on the same file in the shell. My grep command (called both in Java and in bash. I escaped the slash in Java accordingly): /bin/grep -vP --regexp='^[0-9]+\t.*' /usr/local/apache-tomcat-6.0.18/work/Catalina/localhost/saccitic/237482319867147879_1271411421 Java Code: String filepath = "/path/to/file"; String options = "P"; String grepparams = "^[0-9]+\\t.*"; String greppath = "/bin/"; String[] localeArray = new String[] { "LANG=", "LC_COLLATE=C", "LC_CTYPE=UTF-8", "LC_MESSAGES=C", "LC_MONETARY=C", "LC_NUMERIC=C", "LC_TIME=C", "LC_ALL=" }; options = "v"+options; //Assign optional params if (options.contains("P")) { grepparams = "\'"+grepparams+"\'"; //Quote the regex expression if -P flag is used } else { options = "E"+options; //equivalent to calling egrep } proc = sysRuntime.exec(greppath+"/grep -"+options+" --regexp="+grepparams+" "+filepath, localeArray); System.out.println(greppath+"/grep -"+options+" --regexp="+grepparams+" "+filepath); inStream = proc.getInputStream(); The command is supposed to match and discard strings like these: 85295371616 Hi Mr Lee, please be informed that...

I tried passing local information via the environment string array in runtime.exec, but nothing seems to change. Am I passing in the locale information incorrectly, or is the problem something else entirely?

I make histogram of black and white or gray scale image.Is this method of making histogram correct? iif it is correct then how can i do normalization and Equalization of histogram in my App in java using JAI library?my code is below. in my code i make BufferedImage object and then make and plot histogram of that image . enter code here import java.awt.Color; import java.awt.Graphics; import java.awt.image.BufferedImage; import java.io.IOException; import javax.media.jai.JAI; import javax.media.jai.PlanarImage; import javax.swing.*; public class FinalHistogram extends JPanel { static int[] bins = new int[256]; static int[] newBins = new int[256]; static int x1 = 0, y1 = 0; static PlanarImage image = JAI.create("fileload", "alp_finger.tiff"); static BufferedImage bi = image.getAsBufferedImage(); FinalHistogram(int[] pbins) { for (int i = 0; i < 256; i++) { bins[i] = pbins[i]; newBins[i] = 0; } repaint(); } @Override protected void paintComponent(Graphics g) { for (int i = 0; i < 256; i++) { g.drawLine(150 + i, 300, 150 + i, 300 - (bins[i] / 300)); if (i == 0 || i == 255) { String sr = new Integer((i)).toString(); g.drawString(sr, 150 + i, 305); } System.out.println("bin[" + i + "]===" + bins[i]); } } public static void main(String[] args) throws IOException { int[] sbins = new int[256]; int pixel = 0; int k = 0; for (int x = 0; x < bi.getWidth(); x++) { for (int y = 0; y < bi.getHeight(); y++) { pixel = bi.getRaster().getSample(x, y, 0); k = (int) (pixel / 256); sbins[k]++; //pixel = bi.getRGB(x, y) & 0x000000ff; //k=pixel; //int[] pixels = m_image.getRGB(0, 0, m_image.getWidth(), m_image.getHeight(), null, 0, m_image.getWidth()); //short currentValue = 0; //int red,green,blue; //for(int i = 0; i<pixels.length; i++){ //red = (pixels[i] >> 16) & 0x000000FF; //green = (pixels[i] >>8 ) & 0x000000FF; //blue = pixels[i] & 0x000000FF; //currentValue = (short)((red + green + blue) / 3); //Current value gives the average //Disregard the alpha //assert(currentValue >= 0 && currentValue <= 255); //Something is awfully wrong if this goes off... //m_histogramArray[currentValue] += 1; //Increment the specific value of the array //} } } JTabbedPane jtp = new JTabbedPane(); jtp.addTab("Histogram", new JScrollPane(new FinalHistogram(sbins))); JFrame frame = new JFrame(); frame.setSize(500, 500); frame.add(new JScrollPane(jtp)); frame.setVisible(true); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } }

  • How Can I List a TDictionary in Alphabetical Order by Key in Delphi 2009?

    - by lkessler
    How can I use a TEnumerator to go through my TDictionary in sorted order by key? I've got something like this: var Dic: TDictionary<string, string>; begin Dic := TDictionary<string, string>.create; Dic.Add('Tired', 'I have been working on this too long'); Dic.Add('Early', 'It is too early in the morning to be working on this'); Dic.Add('HelpMe', 'I need some help'); Dic.Add('Dumb', 'Yes I know this example is dumb'); { The following is what I don't know how to do } for each string1 (ordered by string1) in Dic do some processing with the current Dic element Dic.Free; end; So I would like to process my dictionary in the order: Dumb, Early, HelpMe, Tired. Unfortunately the Delphi help is very minimal in describing how TEnumerator works and gives no examples that I can find. There is also very little written on the web about using Enumerators with Generics in Delphi.

  • REG GENERIC METHOD

    - by googler1
    Hi buddies, I had a thought on using the generic method in c# as like we do in c++. Normally a method looks like this: public static (void/int/string) methodname((datatype) partameter) { return ...; } I had a thought whether can we implement the generics to this method like this: public static <T> methodname(<T> partameter) { return ...; } Using as a generic to define the datatype. Can anyone pls suggest whether the above declaration is correct and can be used in c#? Thanks in advance.

  • Activator.CreateInstance(string) and Activator.CreateInstance<T>() difference

    - by Juan Manuel Formoso
    No, this is not a question about generics. I have a Factory pattern with several classes with internal constructors (I don't want them being instantiated if not through the factory). My problem is that CreateInstance fails with a "No parameterless constructor defined for this object" error unless I pass "true" on the non-public parameter. Example // Fails Activator.CreateInstance(type); // Works Activator.CreateInstance(type, true); I wanted to make the factory generic to make it a little simpler, like this: public class GenericFactory<T> where T : MyAbstractType { public static T GetInstance() { return Activator.CreateInstance<T>(); } } However, I was unable to find how to pass that "true" parameter for it to accept non-public constructors (internal). Did I miss something or it isn't possible?

  • Scala: "Parameter type in structural refinement may not refer to an abstract type defined outside th

    - by raichoo
    Hi, I'm having a problem with scala generics. While the first function I defined here seems to be perfectly ok, the compiler complains about the second definition with: error: Parameter type in structural refinement may not refer to an abstract type defined outside that refinement def >>[B](a: C[B])(implicit m: Monad[C]): C[B] = { ^ What am I doing wrong here? trait Lifter[C[_]] { implicit def liftToMonad[A](c: C[A]) = new { def >>=[B](f: A => C[B])(implicit m: Monad[C]): C[B] = { m >>= (c, f) } def >>[B](a: C[B])(implicit m: Monad[C]): C[B] = { m >> a } } } IMPORTANT: This is NOT a question about Monads, it's a question about scala polymorphism in general.

  • Why does this Java code not utilize all CPU cores?

    - by ReneS
    The attached simple Java code should load all available cpu core when starting it with the right parameters. So for instance, you start it with java VMTest 8 int 0 and it will start 8 threads that do nothing else than looping and adding 2 to an integer. Something that runs in registers and not even allocates new memory. The problem we are facing now is, that we do not get a 24 core machine loaded (AMD 2 sockets with 12 cores each), when running this simple program (with 24 threads of course). Similar things happen with 2 programs each 12 threads or smaller machines. So our suspicion is that the JVM (Sun JDK 6u20 on Linux x64) does not scale well. Did anyone see similar things or has the ability to run it and report whether or not it runs well on his/her machine (= 8 cores only please)? Ideas? I tried that on Amazon EC2 with 8 cores too, but the virtual machine seems to run different from a real box, so the loading behaves totally strange. package com.test; import java.util.concurrent.ExecutorService; import java.util.concurrent.Executors; import java.util.concurrent.Future; import java.util.concurrent.TimeUnit; public class VMTest { public class IntTask implements Runnable { @Override public void run() { int i = 0; while (true) { i = i + 2; } } } public class StringTask implements Runnable { @Override public void run() { int i = 0; String s; while (true) { i++; s = "s" + Integer.valueOf(i); } } } public class ArrayTask implements Runnable { private final int size; public ArrayTask(int size) { this.size = size; } @Override public void run() { int i = 0; String[] s; while (true) { i++; s = new String[size]; } } } public void doIt(String[] args) throws InterruptedException { final String command = args[1].trim(); ExecutorService executor = Executors.newFixedThreadPool(Integer.valueOf(args[0])); for (int i = 0; i < Integer.valueOf(args[0]); i++) { Runnable runnable = null; if (command.equalsIgnoreCase("int")) { runnable = new IntTask(); } else if (command.equalsIgnoreCase("string")) { runnable = new StringTask(); } Future<?> submit = executor.submit(runnable); } executor.awaitTermination(1, TimeUnit.HOURS); } public static void main(String[] args) throws InterruptedException { if (args.length < 3) { System.err.println("Usage: VMTest threadCount taskDef size"); System.err.println("threadCount: Number 1..n"); System.err.println("taskDef: int string array"); System.err.println("size: size of memory allocation for array, "); System.exit(-1); } new VMTest().doIt(args); } }

  • C# Reflection - How can I tell if object o is of type KeyValuePair and then cast it?

    - by Logan
    Hi All I'm currently trying to write a Dump() method from LinqPad equivalent iin C# for my own amusment. I'm moving from Java to C# and this is an exercise rather than a business requirement. I've got almost everything working except for Dumping a Dictionary. The problem is that KeyValuePair is a Value type. For most other Value types I simply call the ToString method but this is insufficient as the KeyValuePair may contain Enumerables and other objects with undesirable ToString methods. So I need to work out if it's a KeyValuePair and then cast it. In Java I could use wildcard generics for this but I don't know the equivalent in C#. Your quest, given an object o, determine if it's a KeyValuePair and call Print on its key and value. Print(object o) { ... } Thanks!

  • what's a good way to implement something that looks like Dictionary<string, string, Dictionary<strin

    - by jcollum
    I've got a data structure that is Key, Value, OtherValues(key, Value). So the OtherValues are attached to the first Key and aren't always there. I can do this as Dictionary<Key, ValueAndListOfOptionalValues> where ValueAndListOfOptionalValues is a class with a string and a Dictionary<string, string>. I'm wondering if that's really the best way to do it? Sometimes I think that I'm missing some important classes in the Generics namespace, maybe there are better classes out there that I'm not aware of.

  • Using generic type from other generic parameter

    - by DEHAAS
    Hi, I have a question about .net generics. Consider the following code: public class Test<TKey> { TKey Key { get; set; } } public class Wrapper<TValue, TKey> where TValue : Test<TKey> { public TValue Value { get; set; } } Now, when using this code, I could do something like this: Wrapper<Test<int>, int> wrapper = new Wrapper<Test<int>, int>(); The int type parameter has to be provided twice. Is it possible to modify the Wrapper definition, to require TValue to be a generic type, and use this 'nested' generic type parameter insted of the TKey type parameter?

  • Is it normal for Java /Tomcat to keep checking for java_pid<nnnn>.hprof?

    - by Chris
    I was monitoring my JVM running Apache Tomcat 6, running on Windows, and I noticed that every 3 seconds or so the JVM process (C:\Tomcat\bin\tomcat6.exe) is polling to see whether or not C:\Tomcatcat\java_pid3748.hprof exists, where 3748 is the Windows process ID. I haven't seen write to the hprof file, just test for existence. (I'm using Sysinternals Process Monitor (procmon.exe) for this monitoring. In procmon the polling shows up as a QueryDirectory operation, which always returns Result "NO SUCH FILE".) Is this normal, or is this a potential red flag? I gather that these hprof files are generated, perhaps among other times, when you enable the -XX:+HeapDumpOnOutOfMemoryError Java flag. I haven't enabled it myself, though I guess it could be enabled somehow in the Tomcat startup scripts.

  • Where to set java heap options (e.g. -Xmx) for Tomcat 6 under Ubuntu 9.04?

    - by Chris
    I'm running Tomcat using the tomcat6 package from Ubuntu 9.04, which makes a daemon out of Tomcat using jsvc. I'd like to know the proper way to set Java heap options like -Xmx for Tomcat. I'd like to put the configuration wherever is most stylistically correct, and wherever is least likely to be overwritten by Ubuntu package updates. The options I see right now: Hard-code them somewhere in /etc/init.d/tomcat6. Hard-code them somewhere in /usr/share/tomcat6/bin/catalina.sh. Create a line in /usr/share/tomcat6/bin/startup.sh to set CATALINA_OPTS to have the desired flags, and then export CATALINA_OPTS as an environment variable. (This looks like it will get picked up by catalina.sh.) The last option sounds like the best one, and it's advocated (without explanation of why) at http://serverfault.com/questions/121038/increasing-javas-heapspace-in-tomcat-startup-script. But I wanted to get a second opinion. Anyone want to confirm that there isn't a better way?
