  • How to hide some nodes in Richfaces Tree (do not render nodes by condition)?

    - by VestniK
    I have a tree of categories and courses in my SEAM application. Courses may be active and inactive. I want to be able to show only active or all courses in my tree. I've decided to always build complete tree in my PAGE scope component since building this tree is quite expensive operation. I have boolean flag courseActive in the data wrapped by TreeNode<T>. Now I can't find the way to show courses node only if this flag is true. The best result I've achieved with the following code: <h:outputLabel for="showInactiveCheckbox" value="show all courses: "/> <h:selectBooleanCheckbox id="showInactiveCheckbox" value="#{categoryTreeEditorModel.showAllCoursesInTree}"> <a4j:support event="onchange" reRender="categoryTree"/> </h:selectBooleanCheckbox> <rich:tree id="categoryTree" value="#{categoryTree}" var="item" switchType="ajax" ajaxSubmitSelection="true" reRender="categoryTree,controls" adviseNodeOpened="#{categoryTreeActions.adviseRootOpened}" nodeSelectListener="#{categoryTreeActions.processSelection}" nodeFace="#{item.typeName}"> <rich:treeNode type="Category" icon="..." iconLeaf="..."> <h:outputText value="#{item.title}"/> </rich:treeNode> <rich:treeNode type="Course" icon="..." iconLeaf="..." rendered="#{item.courseActive or categoryTreeEditorModel.showAllCoursesInTree}"> <h:outputText rendered="#{item.courseActive}" value="#{item.title}"/> <h:outputText rendered="#{not item.courseActive}" value="#{item.title}" style="color:#{a4jSkin.inactiveTextColor}"/> </rich:treeNode> </rich:tree> the only problem is if some node is not listed in any rich:treeNode it just still shown with title obtained by Object.toString() method insted of being hidden. Does anybody know how to not show some nodes in the Richfases tree according to some condition?

  • Strange behaviour with GregorianCalendar

    - by Spark
    I just encountered a strange behaviour with the GregorianCalendar class, and I was wondering if I really was doing something bad. This only appends when the initialization date's month has an actualMaximum bigger than the month I'm going to set the calendar to. Here is the example code : // today is 2010/05/31 GregorianCalendar cal = new GregorianCalendar(); cal.set(Calendar.YEAR, 2010); cal.set(Calendar.MONTH, 1); // FEBRUARY cal.set(Calendar.DAY_OF_MONTH, cal.getActualMaximum(Calendar.DAY_OF_MONTH)); cal.set(Calendar.HOUR_OF_DAY, cal.getActualMaximum(Calendar.HOUR_OF_DAY)); cal.set(Calendar.MINUTE, cal.getActualMaximum(Calendar.MINUTE)); cal.set(Calendar.SECOND, cal.getActualMaximum(Calendar.SECOND)); cal.set(Calendar.MILLISECOND, cal.getActualMaximum(Calendar.MILLISECOND)); return cal.getTime(); // => 2010/03/03, wtf I know the problem is caused by the fact that the calendar initialization date is a 31 day month ( may ), which mess with the month set to february (28 days). The fix is easy ( just set day_of_month to 1 before setting year and month ), but I was wondering is this really was the wanted behaviour. Any thoughts ?

  • optimistic locking batch update

    - by Priit
    How to use optimistic locking with batch updates? I am using SimpleJdbcTemplate and for single row I can build update sql that increments version column value and includes version in WHERE clause. Unfortunately te result int[] updated = simpleJdbcTemplate.batchUpdate does not contain rowcounts when using oracle driver. All elements are -2 indicating unknown rowcount. Is there some other, more performant way of doing this than executing all updates individually? These batches contain an average of 5 items (only) but may be up to 250.

  • Deploying CXF web service in weblogic 10.

    - by Rig Veda
    Earlier I used to create a war file out of web service and manually deploy it in weblogic. But now (somehow) weblogic doesn't recognize the web-service. Though the earlier jars continue to work. The WSDL's in both the cases are same. Any help would be welcome. But my question is how does weblogic find the web-service. Is it the WSDL or soemthing else?

  • Is it OK to reference 'this' when initializing a field?

    - by parxier
    Is it OK to reference this when initializing a field? public class MainClass { private SomeFieldClass field = new SomeFieldClass(this); public MainClass() {} } Or is it better to do that in constructor? public class MainClass { private SomeFieldClass field; public MainClass() { this.field = new SomeFieldClass(this); } } What is the best practice? I believe first option is better for unit testing and dependency injection. Are there any problems with it?

  • Spring bean creation via deserialization

    - by mdma
    Spring has many different ways of creating beans, but is it possible to create a bean by deserializing a resource? My application has a number of Components, and each manipulates a certain type of data. During test, the data object is instantiated directly and set directly on the component, e.g. component.setData(someDataObject). At runtime, the data is available as a serialized object and read in from the serialized stream by the component. Rather than having each component explicitly deserialize it's data from the stream, it would be more consistent and flexible to have Spring deserialize the data object from a resource. Is there a DeserializerBeanFactory or something similar?

  • Replacing ORM schema without dropping the entire data

    - by Udi
    Hey, I'm using OpenJPA as a JPA provider. Is there a way in which I can recreate the database tables (When an entity changes) without dropping the entire data? When an entity changes, I drop and create every table in the store, and obviously lose the data within. Is there a tool or product to keep the data somehow? Thanks, Udi

  • XSL-stylesheet URI using JAX-WS and Glassfish v3.

    - by Tony
    Hi there. I'm trying to use XSL-stylesheets in order to transform some generated XML-data to HTML-output. The architecture that I'm using is as follows: [Client Side] Web-Browser = [Server Side: Glassfish v3] JSP-pages - Web-Services. My web service generates some XML-data, then I want to format it with XSL-stylesheet, pass the result to JSP-page and show to user. I'm using JAXP for XSL-transformations and I want to create a javax.xml.transform.stream.StreamSource object with XSL-file stream for the javax.xml.transform.Transformer object, but I'm having a difficulty with specifying the path/URL for the XSL-file. So the question is: where should I put my XSL-stylesheets in a project and how should I access them from code? I'm using Glassfish v3 and NetBeans 6.8. Thanks.

  • Printing with an Eclipse RCP program

    - by Raven
    Hi, I am looking for a good, standard way to generate "output" in my RCP programm and print it. This should work as it works on Windows, Mac OS and Linux with the standard print dialog. I am aware of the Birt project, but I could not find any hints about how to implement it within a RCP programm and how to invoke the standard print dialog and how to pass the Birt generated report to the printer. Happy for all hints.

  • What happens to my PriorityQueue if my Comparator throws an exception while it's busy bubbling up or

    - by nieldw
    Hi, I'm trying order pairs of integers ascendantly where a pair is considered less than another pair if both its entries are strictly less than those of the other pair, and larger than the other pair if both its entries are strictly larger than those of the other pair. All other cases are considered incomparable. They way I want to solve this is by defining a Comparator that implements the above, but will throw an exception for incomparable cases, and provide that to a PriorityQueue. Of course, while inserting a pair the priority queue does several comparisons while bubbling the new entry up to its correct position in the heap, and many of these will be comparable. But it may happen during the bubbling process that a pair is encountered with which this new pair is incomparable, and an exception will be thrown. If this happens, what will be the state of the PriorityQueue? Will the pair I was trying to insert sit in the heap at the last position it was in before the exception was thrown? If I use the PriorityQueue's remove(Object o) method, will the PriorityQueue be restored to a consistent state? Thanks

  • Spring 3 MVC - how to turn a form into a query string?

    - by caerphilly
    I have a simple Spring form that gets bound to a form object on post. The http POST handler does some work, and then needs to redirect to a new URL, passing the form data as querystring parameters. So, assuming I have a form backing object with properties "param1" and "param2", I want to build a string that looks something like this: redirect:/app/new/page?param1=value;param2=value Now, Spring will automatically bind values FROM a querystring or a form post into my form object, but I want to GENERATE a querystring with values taken from the form object. Obviously it's trivial to do this manually but since I'm going to have lots of different form backing objects, is there some built-in facility in Spring to generate a query string from a form object, suitable for building into a URL? Thanks.

  • Get Criteria by associationPath

    - by niklassaers
    Hi guys, Every so often, I get a "org.hibernate.QueryException: duplicate association path: myAssociation". This is because the complex criteria I'm working with can define the same path in many places. I'd love to do something like Criteria association = myCriteria.getAssociation("wax"); if(association == null) association = myCriteria.createCriteria("wax"); Is there any such way that I can check if an association is already in place? Cheers Nik

  • how do call a polymorphic function from an agnostic function?

    - by sds
    I have a method foo void foo (String x) { ... } void foo (Integer x) { ... } and I want to call it from a method which does not care about the argument: void bar (Iterable i) { ... for (Object x : i) foo(x); // this is the only time i is used ... } the code above complains that that foo(Object) is not defined and when I add void foo (Object x) { throw new Exception; } then bar(Iterable<String>) calls that instead of foo(String) and throws the exception. How do I avoid having two textually identical definitions of bar(Iterable<String>) and bar(Iterable<Integer>)? I thought I would be able to get away with something like <T> void bar (Iterable<T> i) { ... for (T x : i) foo(x); // this is the only time i is used ... } but then I get cannot find foo(T) error.

    I've got a really nasty problem... I wrote a red5 app and so on and it is running perfectly on my local computer. Now the problem occurs = How can I make this program work on a remote server? Local : OSX 10.5 - red5 0.63 Server: CentOS 5 - red5 0.90 Maybe its because of the version difference... but I can't test red5 0.90 locally becaus it won't start up -.-' and I can't install the 0.63 on the server because of missing dependencies (and broken links to them...)
