  • Displaytag export option is not working

    - by Nirmal
    Hello All, I am using Displaytag framework for pagination & exporting purpose. In that i am also using Strut2Tiles Integration. Whenever i am calling any action class it will returning me a list & through Displaytag i am successfully displaying record on my page. For that my jsp page's code looks like : <s:set name="selectedPageSize" value="selectedPageSize" scope="request"/> <s:set value="accountList" scope="request" name="accountList"/> <display:table name="accountList" export="true" class="table" requestURI="" id="accountList" pagesize="${selectedPageSize}" > <display:setProperty name="export.pdf" value="true" /> <display:column property="id" sortable="true" class="sort-title"/> <display:column property="name" sortable="true"/> <display:column property="contactPerson" sortable="true"/> <display:column property="phone1" sortable="true"/> <display:column property="phone2" sortable="true"/> <display:column property="fax" sortable="true"/> <display:column property="email" sortable="true"/> <display:column property="webSite" sortable="true"/> <display:column property="address1" sortable="true"/> <display:column property="address2" sortable="true"/> <display:column property="countryId.name" title="Country" sortable="true"/> <display:column property="stateId.name" title="State" sortable="true"/> <display:column property="countryId.name" title="City" sortable="true"/> <display:column property="isDeleted" sortable="true"/> <display:column title="Delete"> <s:url id="removeUrl" action="finance/deleteAccount.action"> <s:param name="id" value="#attr.accountList.id" /> </s:url> <s:a href="%{removeUrl}" theme="ajax" targets="accountList">Remove</s:a> </display:column> <display:column title="Update"> <s:url id="updateUrl" action="finance/updateAccount.action"> <s:param value="#attr.accountList.id" name="id"/> </s:url> <s:a href="%{updateUrl}&action=update" targets="accountlist">Update</s:a> </display:column> Actually this page is displaying through tiles configuration. Here i have enabled the export option, so it is showing me the exporting options like CSV, EXCEL, XML. But whenver i am clicking on that CSV link, my web browser hanged, means nothing is displayed on it For that exporting solution i have also added filter in my web.xml. My web.xml looks like: <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <filter> <filter-name>ResponseOverrideFilter</filter-name> <filter-class>org.displaytag.filter.ResponseOverrideFilter</filter-class> </filter> <filter-mapping> <filter-name>ResponseOverrideFilter</filter-name> <url-pattern>*.action</url-pattern> </filter-mapping> <filter-mapping> <filter-name>ResponseOverrideFilter</filter-name> <url-pattern>*.jsp</url-pattern> </filter-mapping> <listener> <listener-class>org.apache.struts2.tiles.StrutsTilesListener</listener-class> </listener> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/classes/webApplicationContext.xml</param-value> </context-param> <welcome-file-list> <welcome-file>jsp/welcome.jsp</welcome-file> </welcome-file-list> I have also included following list of libraries of displaytag : 1) displaytag-1.2.jar 2) displaytag-export-poi-1.2.jar 3) displaytag-portlet-1.2.jar The exception that i am getting is : 2009-05-09 12:02:38,234 DEBUG (org.displaytag.tags.TableTag:1524) - Exportfilter NOT enabled 2009-05-09 12:02:38,312 WARN (org.displaytag.tags.TableTag:63) - Exception: [.TableTag] Unable to reset response before returning exported data.

  • What is the best IDE?

    - by venom
    Hello. As a not so experienced man in programming, I start to use netbeans PLATFORM. And I am really impressed by its power (for rich desktop app). I have been learning the programming in another way on university. I have never thought that something as powerful as nb Platform exists. My idea was that 30 people work on some rich desktop app for more than year to make it "beta". Now I know, that it is much more easier. But, I have never be satisfied with my own opinions about "something is best". I am still looking for better mouse trap. So the question is: What is most powerful IDE you know? (it does not strongly depends on language, it means if some combination of language/IDE is really powerful, feel free to answer.)

  • PulpCore music playback - loop sound and animate volume

    - by Peter Perhác
    I have been experimenting with PulpCore, trying to create my own tower defence game (not-playable yet), and I am enjoying it very much I ran into a problem that I can't quite figure out. I extended PulpCore with the JOrbis thing to allow OGG files to be played. Works fine. However, pulpCore seems to have a problem with looping the sound WHILE animating the volume level. I tried this with wav file too, to make sure it isn't jOrbis that breaks it. The code is like this: Sound bgMusic = Sound.load("music/music.ogg"); Playback musicPlayback; ... musicVolume = new Fixed(0.75); musicPlayback = bgMusic.loop(musicVolume); //TODO figure out why it's NOT looping when volume is animated // musicVolume.animate(0, musicVolume.get(), FADE_IN_TIME); This code, for as long as the last line is commented out, plays the music.ogg again and again in an endless loop (which I can stop by calling stop on the Playback object returned from loop(). However, I would like the music to fade in smoothly, so following the advice of the PulpCore API docs, I added the last line which will create the fade-in but the music will only play once and then stop. I wonder why is that? Here is a bit of the documentation: Playback pulpcore.sound.Sound.loop(Fixed level) Loops this sound clip with the specified volume level (0.0 to 1.0). The level may have a property animation attached. Parameters: level Returns: a Playback object for this unique sound playback (one Sound can have many simultaneous Playback objects) or null if the sound could not be played. So what could be the problem? I repeat, with the last line, the sound fades in but doesn't loop, without it it loops but starts with the specified 0.75 volume level. Why can't I animate the volume of the looped music playback? What am I doing wrong? Anyone has any experience with pulpCore and has come across this problem? Anyone could please download PulpCore and try to loop music which fades-in (out)? note: I need to keep a reference to the Playback object returned so I can kill music later.

  • Background settings for a JDesktopPane

    - by EricR
    I'm using a self-made DesktopPaneUI for a JDesktopPane, I've written the proper methods for the class, and I'm running into trouble. When I resize the JDesktopPane, the background image doesn't resize with the frame. The image appears to be clipped at the size it was when the window initially opened. I'm giving it an image larger than the window, and I'm still having this problem. Here's my method call inside the constructor of my desktopUI class. super(); this.background = javax.imageio.ImageIO.read(new File(fileName)); Is there a way I can change my main class where I set the UI, or the myDesktopPaneUI class such that the background still fills the window when the JDesktopPane changes size? setUI(new myDesktopPaneUI("media/bg.jpg"));

  • XStream or Simple

    - by Adeel Ansari
    I need to decide on which one to use. My case is pretty simple. I need to convert a simple POJO/Bean to XML, and then back. Nothing special. One thing I am looking for is it should include the parent properties as well. Best would be if it can work on super type, which can be just a marker interface. If anyone can compare these two with cons and pros, and which thing is missing in which one. I know that XStream supports JSON too, thats a plus. But Simple looked simpler in a glance, if we set JSON aside. Whats the future of Simple in terms of development and community? XStream is quite popular I believe, even the word, "XStream", hit many threads on SO. Thanks.

  • How to manage a large dataset using Spring MySQL and RowCallbackHandler

    - by rmarimon
    I'm trying to go over each row of a table in MySQL using Spring and a JdbcTemplate. If I'm not mistaken this should be as simple as: JdbcTemplate template = new JdbcTemplate(datasource); template.setFetchSize(1); // template.setFetchSize(Integer.MIN_VALUE) does not work either template.query("SELECT * FROM cdr", new RowCallbackHandler() { public void processRow(ResultSet rs) throws SQLException { System.out.println(rs.getString("src")); } }); I get an OutOfMemoryError because it is trying to read the whole thing. Any ideas?

  • DataSource for Tomcat web app, Spring and Hibernate

    - by EugeneP
    Web app runs on Tomcat. Datasource is configured with Spring configuration, and is used by Hibernate. If we cannot use JNDI, what would you suggest to use as a DataSource? org.springframework.jdbc.datasource.DriverManagerDataSource will be ok? It's not very good, but sincerely speaking, it can be used on production server, right? Just a bit of headache with too frequent connection reopening. Also, we can use BasicDataSource from Apache. It's much better of course, but here's the question. IF WE DON'T USE JNDI, THEN: If every instance of an app will create its own copy of a DataSource, and every DataSource can have 5 open connections, what do we get? Num_of_running_apps * Num_of_max_active_connections = max active open connection on a DB for this user? Second question: from the perspective of Hibernate, is there any difference about what datasource implementation is used? Will it work with no matter what datasource perfectly and in a stable way?

  • Android popup style activity which sits on top of any other apps

    - by RenegadeAndy
    What I want to create is a popup style application. I have a service in the background - something arrives on the queue and i want an activity to start to inform the user - very very similar to the functionality of SMSPopup app. So I have the code where something arrives on the queue and it calls my activity. However for some reason the activity always shows on top of the originally started activity instead of just appearing on the main desktop of the android device. As an example: I have the main activity which is shown when the application is run I have the service which checks queue I have a popup activity. When i start the main activity it starts the service - I can now close this. I then have something on the queue and it creates the popup activity which launches the main activity with the popup on top of it :S How do I stop this and have it behave as i want... The popup class is : package com.andy.tabletsms.work; import com.andy.tabletsms.tablet.R; import android.app.Activity; import android.content.Context; import android.content.Intent; import android.os.Bundle; import android.view.Gravity; import android.view.LayoutInflater; import android.view.View; import android.view.View.OnClickListener; import android.view.ViewGroup; import android.widget.Button; import android.widget.PopupWindow; import android.widget.TextView; import android.widget.Toast; public class SMSPopup extends Activity implements OnClickListener{ public static String msg; @Override public void onCreate(Bundle bundle){ super.onCreate(bundle); // Toast.makeText(getApplicationContext(), msg, Toast.LENGTH_LONG).show(); this.setContentView(R.layout.popup); TextView tv = (TextView)findViewById(R.id.txtLbl); Intent intent = getIntent(); if (intent != null){ Bundle bb = intent.getExtras(); if (bb != null){ msg = bb.getString("com.andy.tabletsms.message"); } } if(msg == null){ msg = "LOLOLOL"; } tv.setText(msg); Button b = (Button)findViewById(R.id.closeBtn); b.setOnClickListener(this); } @Override public void onClick(View v) { this.finish(); } } and I call the activity from a broadcast receiver which checks the queue every 30 seconds or so : if(main.msgs.size()0){ Intent testActivityIntent = new Intent(context.getApplicationContext(), com.andy.tabletsms.work.SMSPopup.class); testActivityIntent.putExtra("com.andy.tabletsms.message", main.msgs.get(0)); testActivityIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startActivity(testActivityIntent); } The layout is here : http://pastebin.com/F25u6wdM

  • JAXB - representing element as boolean?

    - by Marcus
    We have this XML: <Summary> <ValueA>xxx</ValueA> <ValueB/> </Summary> <ValueB/> will never have any attributes or inner elements. It's a boolean type element - it exists (true) or it doesn't (false). JAXB generated a Summary class with a String valueA member, which is good. But for ValueB, JAXB generated a ValueB inner class and a corresponding member: @XmlElement(name = "ValueB") protected Summary.ValueB valueB; But what I'd like is a boolean member and no inner class: @XmlElement(name = "ValueB") protected boolean valueB; How can you do this? I'm not looking to regenerate the classes, I'd like to just make the code change manually.

  • Does JAXWS client make difference between an empty collection and a null collection value as returne

    - by snowflake
    Since JAX-WS rely on JAXB, and since I observed the code that unpack the XML bean in JAX-B Reference Implementation, I guess the difference is not made and that a JAXWS client always return an empty collection, even the webservice result was a null element: public T startPacking(BeanT bean, Accessor<BeanT, T> acc) throws AccessorException { T collection = acc.get(bean); if(collection==null) { collection = ClassFactory.create(implClass); if(!acc.isAdapted()) acc.set(bean,collection); } collection.clear(); return collection; } I agree that for best interoperability service contracts should be non ambiguous and avoid such differences, but it seems that the JAX-WS service I'm invoking (hosted on a Jboss server with Jbossws implementation) is returning as expected either null either empty collection (tested with SoapUI). I used for my test code generated by wsimport. Return element is defined as: @XmlElement(name = "return", nillable = true) protected List<String> _return; I even tested to change the Response class getReturn method from : public List<String> getReturn() { if (_return == null) { _return = new ArrayList<String>(); } return this._return; } to public List<String> getReturn() { return this._return; } but without success. Any helpful information/comment regarding this problem is welcome !

  • How to pass get-parameter to backing bean in jsf?

    - by Roman
    I have get parameter with name controller. When I try to pass it (with propertyChangeListener) to my backing bean I get null instead of the real value of the parameter: <h:commandButton value="#{msg['mail.send']}" styleClass="mailbutton" action="#{mailSender.sendMail}"> <f:setPropertyActionListener target="#{mailSender.controllerName}" value="{#param.controller}"/> </h:commandButton> So, I have two questions: What is the proper way to set bean property with a get-parameter value? Actually, I've already get the value from ExternalContext#getRequestParam but maybe there are some other solutions. More interesting question: why propertyActionListener didn't work here? What does it do actually? (again I have some thoughts about it but it would be nice to read more comprehensive explanations).

  • Configure WebLogic MDB to listen to Foreing AMQ Server

    - by eliel.lobo
    I'm trying to create an MDB(EJB 3.0) on WebLogic 10.3.5. to listen to a Queue in an external AMQ server. but after much work and combination of tutorials i get the followin error when deployin on WwebLogic. [EJB:015027]The Message-Driven EJB is transactional but JMS connection factory referenced by the JNDI name: ActiveMQXAConnectionFactory is not a JMS XA connection factory. Here is a brief of the work i have done: I have added the corresponding libraries to my WLS classpath (following thos tuturial http://amadei.com.br/blog/index.php/connecting-weblogic-and-activemq) and I have created the corresponding JMS Modules as indicated in the tutorial. As connection factory I have used ActiveMQConnectionFactory initially and ActiveMQXAConnectionFactory later, I also ignome the jms. notation an just put plain names as testQueue. Then create a simple MDB whit the following structure. I explicitly defined "connectionFactoryJndiName" property because otherwise it assumes a WebLogic connection factory which is not found an then raises an error. @MessageDriven( activationConfig = { @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"), @ActivationConfigProperty(propertyName = "destination", propertyValue = "testQueue"), @ActivationConfigProperty(propertyName = "connectionFactoryJndiName", propertyValue = "ActiveMQXAConnectionFactory") }, mappedName = "testQueue") public class ROMELReceiver implements MessageListener { /** * Default constructor. */ public ROMELReceiver() { // TODO Auto-generated constructor stub } /** * @see MessageListener#onMessage(Message) */ public void onMessage(Message message) { System.out.println("Message received"); } } At this point I'm stuck with the error mentioned above. Even though I use ActiveMQXAConnectionFactory instead of simply ActiveMQConnectionFactory, JNDI resources tree in web logic server shows org.apache.activemq.ActiveMQConnectionFactory as class for my configured connection factory. am i missing something? or is this just a completely wrong way to connect WebLogic whith AMQ? Thanks in advance.

  • Eclipse RCP: Making use of configuration directory

    - by Dot
    Hello, My Eclipse RCP application requires a configuration file that contains some information to connect to a remote database. Where is the best location to store this configuration file? Can I use the default configuration directory (where 'config.ini' is usually stored) for this purpose? If so, how can I get a File instance to this location programmatically? I also note that this directory does not exist in my Eclipse IDE. Thanks.

  • Eclipse RCP: Actions vs Commands - would like an update

    - by nEm
    I know this question has been asked before but it was in 2009 and I haven't found anything more recent either on the web. I was wondering if the answer in that still holds or can it be updated? I am just starting work on an RCP and I haven't been able to decide between actions and commands for my menu items. I will be using a lot of the ones provided by Eclipse such as the Edit, File and some of their sub menu items as well. Since it has been nearly two years for the answer provided in the '09 question, I just wanted to make sure there is nothing else that could sway my decision in either direction or maybe if there have been some new developments that I am not aware of.
