  • form:select items problem in spring mvc portlet

    - by dhaval
    I have a set of drop-down control which I want to render with my custom tag library. The following is the code of the tag lib: <spring:bind path="${path}"> <c:choose> <c:when test="${readOnly}"> <span class="readOnly">${status.value}</span> </c:when> <c:otherwise> <form:select path="${path }" itemLabel="${label }" itemValue="${value }" items="${itemList}"> </form:select> </c:otherwise> </c:choose> And this is the code I have written in the JSP file: <tag:conditionalListControl path="model.selectedCountry" readOnly="false" label="name" value="id" listItems="model.countryList" className="simple" /> Upon execution the paring returns the following error: [jsp:165] javax.servlet.jsp.JspException: Type [java.lang.String] is not valid for option items But if i change the items="${itemList}" to items="${model.countryList}" which is the list I want to display, it works fine without any problem and also bind to required variables on form submit. But i don't want to hard code any variables in the tag lib. Any suggestions???

  • [Netbeans 6.9] Java MethodOverloading error with double values

  • iBatis not populating object when there are no rows found.

    - by Omnipresent
    I am running a stored procedure that returns 2 cursors and none of them have any data. I have the following mapping xml: <resultMap id="resultMap1" class="HashMap"> <result property="firstName" columnIndex="2"/> </resultMap> <resultMap id="resultMap2" class="com.somePackage.MyBean"> <result property="unitStreetName" column="street_name"/> </resultMap> <parameterMap id="parmmap" class="map"> <parameter property="id" jdbcType="String" javaType="java.lang.String" mode="IN"/> <parameter property="Result0" jdbcType="ORACLECURSOR" javaType="java.sql.ResultSet" mode="OUT" resultMap="resultMap1"/> <parameter property="Result1" jdbcType="ORACLECURSOR" javaType="java.sql.ResultSet" mode="OUT" resultMap="resultMap2"/> </parameterMap> <procedure id="proc" parameterMap="parmmap"> { call my_sp (?,?,?) } </procedure> First result set is being put in a HashMap...second resultSet is being put in a MyBean class. code in my DAO follows: HashMap map = new HashMap() map.put("id", "1234"); getSqlMapClientTemplate().queryForList("mymap.proc", map); HashMap result1 = (HashMap)((List)parmMap.get("Result0")).get(0); MyBean myObject = (MyBean)((List)parmMap.get("Result1")).get(0);//code fails here in the last line above..my code fails. It fails because second cursor has no rows and thats why nothing is put into the list. However, first cursor returns nothing as well but since results are being put into a HashMap the list for first cursor atleast has HashMap object inside it.. Why this difference? is there a way to make iBatis put an object of MyBean inside the list even if there are no rows returned? Or should I be handling this in my DAO...I want to avoid handling it in the DAO because I have whole bunch of DAO's like these.

  • Maven + AspectJ - all steps to configure it

    - by Alice
    I have a problem with applying aspects to my maven project. Probably I am missing something, so I've made a list of steps. Could you please check if it is correct? Let say in projectA is an aspect class and in projectB classes, which should be changed by aspects. Create maven project ProjectA with AspectJ class add Aspectj plugin and dependency Add ProjectA as a dependency to projectB pom.xml Add to projectB pom.xml plugin " <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>aspectj-maven-plugin</artifactId> <version>1.4</version> <executions> <execution> <goals> <goal>compile</goal> <goal>test-compile</goal> </goals> </execution> </executions> <configuration> <source>${maven.compiler.source}</source> <target>${maven.compiler.target}</target> <aspectLibraries> <aspectLibrary> <groupId>ProjectA</groupId> <artifactId>ProjectA</artifactId> </aspectLibrary> </aspectLibraries> </configuration> </plugin> Add aspectj dependency After all these steps my problem is, that during compilation I get: [WARNING] advice defined in AspectE has not been applied [Xlint:adviceDidNotMatch] And then when I run my program: Exception in thread "FeatureExcutionThread" java.lang.NoClassDefFoundError: AspectE

  • Jersey, JAXB and getting an objectextending an abstract class as a parameter

    - by krajol
    I want to get an object as a parameter of a POST request. I got an abstract superclass that is called Promotion and subclasses Product and Percent. Here's how I try to get a request: @POST @Consumes(MediaType.APPLICATION_XML) @Produces(MediaType.APPLICATION_XML) @Path("promotion/") public Promotion createPromotion(Promotion promotion) { Product p = (Product) promotion; System.out.println(p.getPriceAfter()); return promotion; } and here's how I use JAXB in classes' definitions: @XmlRootElement(name="promotion") @XmlSeeAlso({Product.class,Percent.class}) public abstract class Promotion { //body } @XmlRootElement(name="promotion") public class Product extends Promotion { //body } @XmlRootElement(name="promotion") public class Percent extends Promotion { //body } So the problem now is when I send a POST request with a body like this: <promotion> <priceBefore>34.5</priceBefore> <marked>false</marked> <distance>44</distance> </promotion> and I try to cast it to Product (as in this case, fields 'marked' and 'distance' are from Promotion class and 'priceBefore' is from Product class) I get an Exception: java.lang.ClassCastException: Percent cannot be cast to Product. It seems like Percent is chosen as a 'default' subclass. Why is that and how can I get an object that is a Product?

  • Android - BitmapFactory.decodeByteArray - OutOfMemoryError (OOM)

    - by Bob Keathley
    I have read 100s of article about the OOM problem. Most are in regard to large bitmaps. I am doing a mapping application where we download 256x256 weather overlay tiles. Most are totally transparent and very small. I just got a crash on a bitmap stream that was 442 Bytes long while calling BitmapFactory.decodeByteArray(....). The Exception states: java.lang.OutOfMemoryError: bitmap size exceeds VM budget(Heap Size=9415KB, Allocated=5192KB, Bitmap Size=23671KB) The code is: protected Bitmap retrieveImageData() throws IOException { URL url = new URL(imageUrl); InputStream in = null; OutputStream out = null; HttpURLConnection connection = (HttpURLConnection) url.openConnection(); // determine the image size and allocate a buffer int fileSize = connection.getContentLength(); if (fileSize < 0) { return null; } byte[] imageData = new byte[fileSize]; // download the file //Log.d(LOG_TAG, "fetching image " + imageUrl + " (" + fileSize + ")"); BufferedInputStream istream = new BufferedInputStream(connection.getInputStream()); int bytesRead = 0; int offset = 0; while (bytesRead != -1 && offset < fileSize) { bytesRead = istream.read(imageData, offset, fileSize - offset); offset += bytesRead; } // clean up istream.close(); connection.disconnect(); Bitmap bitmap = null; try { bitmap = BitmapFactory.decodeByteArray(imageData, 0, bytesRead); } catch (OutOfMemoryError e) { Log.e("Map", "Tile Loader (241) Out Of Memory Error " + e.getLocalizedMessage()); System.gc(); } return bitmap; } Here is what I see in the debugger: bytesRead = 442 So the Bitmap data is 442 Bytes. Why would it be trying to create a 23671KB Bitmap and running out of memory?

  • Are Thread.stop and friends ever safe in Java?

    - by Stephen C
    The stop(), suspend(), and resume() in java.lang.Thread are deprecated because they are unsafe. The Sun recommended work around is to use Thread.interrupt(), but that approach doesn't work in all cases. For example, if you are call a library method that doesn't explicitly or implicitly check the interrupted flag, you have no choice but to wait for the call to finish. So, I'm wondering if it is possible to characterize situations where it is (provably) safe to call stop() on a Thread. For example, would it be safe to stop() a thread that did nothing but call find(...) or match(...) on a java.util.regex.Matcher? (If there are any Sun engineers reading this ... a definitive answer would be really appreciated.) EDIT: Answers that simply restate the mantra that you should not call stop() because it is deprecated, unsafe, whatever are missing the point of this question. I know that that it is genuinely unsafe in the majority of cases, and that if there is a viable alternative you should always use that instead. This question is about the subset cases where it is safe. Specifically, what is that subset?

  • Is private method in spring service implement class thread safe

    - by Roger Ray
    I got a service in an project using Spring framework. public class MyServiceImpl implements IMyService { public MyObject foo(SomeObject obj) { MyObject myobj = this.mapToMyObject(obj); myobj.setLastUpdatedDate(new Date()); return myobj; } private MyObject mapToMyObject(SomeObject obj){ MyObject myojb = new MyObject(); ConvertUtils.register(new MyNullConvertor(), String.class); ConvertUtils.register(new StringConvertorForDateType(), Date.class); BeanUtils.copyProperties(myojb , obj); ConvertUtils.deregister(Date.class); return myojb; } } Then I got a class to call foo() in multi-thread; There goes the problem. In some of the threads, I got error when calling BeanUtils.copyProperties(myojb , obj); saying Cannot invoke com.my.MyObject.setStartDate - java.lang.ClassCastException@2da93171 obviously, this is caused by ConvertUtils.deregister(Date.class) which is supposed to be called after BeanUtils.copyProperties(myojb , obj);. It looks like one of the threads deregistered the Date class out while another thread was just about to call BeanUtils.copyProperties(myojb , obj);. So My question is how do I make the private method mapToMyObject() thread safe? Or simply make the BeanUtils thread safe when it's used in a private method. And will the problem still be there if I keep the code this way but instead I call this foo() method in sevlet? If many sevlets call at the same time, would this be a multi-thread case as well?

  • Best practice for managing changes to 3rd party open source libraries?

    - by Jeff Knecht
    On a recent project, I had to modify an open source library to address a functional deficiency. I followed the SVN best practice of creating a "vendor source" repository and made my changes there. I also submitted the patch to the mailing list of that project. Unfortunately, the project only has a couple of maintainers and they are very slow to commit updates. At some point, I expect the library to be updated, and I expect that my project will want to use the upgraded library. But now I have a potential problem... I don't know whether my patch will have been applied to this future release of the 3rd party library. I also don't know whether my patch will even still be compatible with the internal implementation of the upgraded components. And in all likelihood, someone else will be maintaining my project by that point. Should I name the library in a special way so it is clear that we made special modifications (eg. commons-lang-2.x-for-my-project.jar)? Should I just document the patch and reference the SVN location and a link to the mailing list item in a README? No option that I can think of seems to be fool-proof in an upgrade scenario. What is the best practice for this?

  • Need help extrapolating Java code

    - by Berlioz
    If anyone familiar with Rebecca Wirfs-Brock, she has a piece of Java code found in her book titled, Object Design: Roles, Responsibilities, and Collaborations. Here is the quote Applying Double Dispatch to a Specific Problem To implement the game Rock, Paper, Scissors we need to write code that determines whether one object “beats” another. The game has nine possible outcomes based on the three kinds of objects. The number of interactions is the cross product of the kinds of objects. Case or switch statements are often governed by the type of data that is being operated on. The object-oriented language equivalent is to base its actions on the class of some other object. In Java, it looks like this Here is the piece of Java code on page 16 ' import java.util.*; import java.lang.*; public class Rock { public static void main(String args[]) { } public static boolean beats(GameObject object) { if (object.getClass.getName().equals("Rock")) { result = false; } else if (object.getClass.getName().equals("Paper")) { result = false; } else if(object.getClass.getName().equals("Scissors")) { result = true; } return result; } }' ===This is not a very good solution. First, the receiver needs to know too much about the argument. Second, there is one of these nested conditional statements in each of the three classes. If new kinds of objects could be added to the game, each of the three classes would have to be modified. Can anyone share with me how to get this "less than optimal" piece of code to work in order to see it 'working'. She proceeds to demonstrate a better way, but I will spare you. Thanks

  • How to convert a list object to bigdecimal in prepared statement?

    - by user1103504
    I am using prepared statement for bulk insertion of records. Iam iterating a list which contains values and their dataTypes differ. One of the data type is BigDecimal and when i try to set calling preparedstatement, it is throwing null pointer exception. My code int count = 1; for (int j = 0; j < list.size(); j++) { if(list.get(j) instanceof Timestamp) { ps.setTimestamp(count, (Timestamp) list.get(j)); } else if(list.get(j) instanceof java.lang.Character) { ps.setString(count, String.valueOf(list.get(j))); } else if(list.get(j) instanceof java.math.BigDecimal) { ps.setBigDecimal(count, (java.math.BigDecimal)list.get(j)); } else { ps.setObject(count, list.get(j)); } count++; } I tried 2 ways to convert, casting the object and tried to create a new object of type BigDecimal ps.setBigDecimal(count, new BigDecimal(list.get(j).toString)); both donot solve my problem. It is throwing null pointer exception. help is appreciated. Thanks

  • Javascript memory leak/ performance issue?

    - by Tom
    I just cannot for the life of me figure out this memory leak in Internet Explorer. insertTags simple takes string str and places each word within start and end tags for HTML (usually anchor tags). transliterate is for arabic numbers, and replaces normal numbers 0-9 with a &#..n; XML identity for their arabic counterparts. fragment = document.createDocumentFragment(); for (i = 0, e = response.verses.length; i < e; i++) { fragment.appendChild((function(){ p = document.createElement('p'); p.setAttribute('lang', (response.unicode) ? 'ar' : 'en'); p.innerHTML = ((response.unicode) ? (response.surah + ':' + (i+1)).transliterate() : response.surah + ':' + (i+1)) + ' ' + insertTags(response.verses[i], '<a href="#" onclick="window.popup(this);return false;" class="match">', '</a>'); try { return p } finally { p = null; } })()); } params[0].appendChild( fragment ); fragment = null; I would love some links other than MSDN and about.com, because neither of them have sufficiently explained to me why my script leaks memory. I am sure this is the problem, because without it everything runs fast (but nothing displays). I've read that doing a lot of DOM manipulations can be dangerous, but the for loops a max of 286 times (# of verses in surah 2, the longest surah in the Qur'an).

  • Compiling scalafx for Java 7u7 (that contains JavaFX 2.2) on OS X

    - by akauppi
    The compilation instructions of scalafx says to do: export JAVAFX_HOME=/Path/To/javafx-sdk2.1.0-beta sbt clean compile package make-pom package-src However, with the new packaging of JavaFX as part of the Java JDK itself (i.e. 7u7 for OS X) there no longer seems to be such a 'javafx-sdkx.x.x' folder. The Oracle docs say that JavaFX JDK is placed alongside the main Java JDK (in same folders). So I do: $ export JAVAFX_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_07.jdk $ sbt clean [warn] Using project/plugins/ (/Users/asko/Sources/scalafx/project/plugins) for plugin configuration is deprecated. [warn] Put .sbt plugin definitions directly in project/, [warn] .scala plugin definitions in project/project/, [warn] and remove the project/plugins/ directory. [info] Loading project definition from /Users/asko/Sources/scalafx/project/plugins/project [info] Loading project definition from /Users/asko/Sources/scalafx/project/plugins [error] java.lang.NullPointerException [error] Use 'last' for the full log. Project loading failed: (r)etry, (q)uit, (l)ast, or (i)gnore? Am I doing something wrong or is scalafx not yet compatible with the latest Java release (7u7, JavaFX 2.2). What can I do? http://code.google.com/p/scalafx/ Addendum ..and finally (following Igor's solution below) sbt run launches the colorful circles demo easily (well, if one has a supported GPU that is). Oracle claims that "JavaFX supports graphic hardware acceleration on any Mac OS X system that is Lion or later" but I am inclined to think the NVidia powered Mac Mini I'm using does software rendering. A recent MacBook Air (core i7) is a complete different beast! :)

  • Javascript style variables with "-" in their name aren't able to be changed?

    - by William
    Okay, so this bug has cost me quite a bit of time and embarrassment. It seems that any style variable with a - in it's name can't be modified by javascript. As seen here: <!DOCTYPE html> <html lang="en"> <head> <title>Class Test</title> <meta charset="utf-8" /> <style> body { text-align: center; background-color: #ffffff;} #box { position: absolute; left: 610px; top: 80px; height: 50px; width: 50px; background-color: #ff0000; color: #000000;} </style> <script type="text/javascript"> var box = 0; </script> </head> <body> <div id="box" ></div> <script type="text/javascript"> box = document.getElementById('box'); box.style.background-color = "#0000ff"; </script> </body> </html> The box in said example will just remain red. So how do I change a style variable with a - in it's name?

    I can't get my messages in messages.properties to be used during Spring validation of my form backing objects. app-config.xml: <bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource"> <property name="basename" value="messages" /> </bean> WEB-INF/classes/messages.properties: NotEmpty=This field should not be empty. Form Backing Object: ... @NotEmpty @Size(min=6, max=25) private String password; ... When I loop through all errors in the BindingResult and output the ObjectError's toString I get this: Field error in object 'settingsForm' on field 'password': rejected value []; codes [NotEmpty.settingsForm.password,NotEmpty.password,NotEmpty.java.lang.String,NotEmpty]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [settingsForm.password,password]; arguments []; default message [password]]; default message [may not be empty] As you can see the default message is "may not be empty" instead of my message "This field should not be empty". I do get my correct message if I inject the messageSource into a controller and output this: messageSource.getMessage("NotEmpty", new Object [] {"password"}, "default empty message", null); So why isn't the validation using my messages.properties? I'm running Spring 3.1.1. Thanks!

  • ADO.NET Data Services Media type requires a ';' character before a parameter definition.

    - by idahosaedokpayi
    I am experimenting with ADO.NET and I am seeing this error on the second attempt to browse the service: <?xml version="1.0" encoding="utf-8" standalone="yes" ?> <error xmlns="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"> <code /> <message xml:lang="en-US">Media type requires a ';' character before a parameter definition.</message> </error> The first attempt is normal. I am working with an exactly identical service on an internal development network and it is fine. I am including my connection string: <add name="J4Entities" connectionString="metadata=res://*;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=MNSTSQL01N;Initial Catalog=J4;Integrated Security=True;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient"/> and my Data service class: using System; using System.Data.Services; using System.Collections.Generic; using System.Linq; using System.ServiceModel.Web; public class Data : DataService< J4Model.J4Entities > { // This method is called only once to initialize service-wide policies. public static void InitializeService(IDataServiceConfiguration config) { // TODO: set rules to indicate which entity sets and service operations are visible, updatable, etc. // Examples: config.SetEntitySetAccessRule("*", EntitySetRights.AllRead); // config.SetServiceOperationAccessRule("MyServiceOperation", ServiceOperationRights.All); } } Is there something obvious I am not doing?

  • Can't get my Jscrollpane working in my Jtextarea

    - by Bobski
    I've looked around quite a lot on google and followed several examples however I can't seem to get my JScrollPane working on a textarea in a JPanel. import javax.swing.*; import java.awt.*; import java.awt.event.*; import java.lang.*; import javax.swing.event.*; class main { public static void main(String Args[]) { frame f1 = new frame(); } } class frame extends JFrame { JButton B = new JButton("B"); JButton button = new JButton("A"); JTextArea E = new JTextArea("some lines", 10, 20); JScrollPane scrollBar = new JScrollPane(E); JPanel grid = new JPanel (); frame() { setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setSize(500,800); setTitle("Mobile Phone App"); setLocationRelativeTo(null); E.setLineWrap(true); E.setEditable(false); grid.add(button); button.addActionListener(new action()); grid.add(B); B.addActionListener(new action()); //grid.add(E); grid.getContentPane().add(scrollBar); add(grid); setVisible(true); } class action implements ActionListener { public void actionPerformed(ActionEvent e) { String V = E.getText(); if(e.getSource() == button) { E.setText(V + "A is pressed"); } if(e.getSource() == B) { E.setText(V + "B is pressed"); } } } } Would be great if someone can see where I am going wrong. I added JscrollPane in which I added the text area "e" in it.

  • initWithContentsOfURL seems to have issues with "long" URLs

    - by samsam
    Hi there I'm facing a rather strange Issue when trying to load data from an XML-Webservice. The webservice allows me to pass separated identifiers within the URL-Request. It is therefore possible for the URL to become rather long (240 characters). If I open said URL in firefox the response arrives as planned, if I execute the following code xmlData remains empty. NSString *baseUrl = [[NSString alloc] initWithString:[[[[kSearchDateTimeRequestTV stringByReplacingOccurrencesOfString:@"{LANG}" withString:appLanguageCode] stringByReplacingOccurrencesOfString:@"{IDENTIFIERS}" withString:myIdentifiers] stringByReplacingOccurrencesOfString:@"{STARTTICKS}" withString:[NSString stringWithFormat:@"%@", [[startTime getTicks] descriptionWithLocale:nil]]] stringByReplacingOccurrencesOfString:@"{ENDTICKS}" withString:[NSString stringWithFormat:@"%@", [[endTime getTicks] descriptionWithLocale:nil]]]]; NSLog(baseUrl); //looks good, if openend in browser, returnvalue is ok urlRequest = [NSURL URLWithString:baseUrl]; NSString *xmlData = [NSString stringWithContentsOfURL:urlRequest encoding:NSUTF8StringEncoding error:&err]; //err is nil, therefore i guess everything must be ok... :( NSLog(xmlData); //nothing... is there any sort of URL-Length restriction, does the same problem happened to anyone of you as well? whats a good workaround? thanks for your help sam

  • CSS 100 percent height body and element

    - by Tim
    I am having an issue making one of my elements 100% within an overall layout that is 100%. I have tried different positioning solutions and I either end up with hidden content the floats behind the footer at the bottom, or the content ends up going behind the footer, and carrys on after the footer. Here is what I have for the page layout. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" lang="en-US"> <head> <style> *{margin:0} html,body{margin:0; padding:0; height:100%} .wrapper{position:relative; margin:0 auto -200px; height:auto !important; height:100%; min-height:100%} .container{width:930px; margin:0 auto; text-align:left} .right{float:right; width:680px; background:#FFF; margin:60px 10px 0 0; padding:0} .left{float:left; width:240px} .content{padding:10px} .footer{position:absolute; width:100%} .footer,.push{height:200px} </style> </head> <body> <div class="wrapper"> left content footer </div> </body> </html> The layout for the page being 100% height and footer at the bottom works it just the div with the class name content that I would like to be 100% as well and push the footer further down if the content reaches the footer and not disappear. Any help most appreciated. http://img686.imageshack.us/img686/7725/screenshotbj.png
