  • Can I inject a SessionBean into a JEE AroundInvoke-Interceptor?

    - by Michael Locher
    I have an EAR with modules: foo-api.jar foo-impl.jar interceptor.jar In foo-api there is: @Local FooService // (interface of a local stateless session bean) In foo-impl there is: @Stateless FooServiceImpl implements FooService //(implementation of the foo service) In interceptor.jar I want public class BazInterceptor { @EJB private FooService foo; @AroundInvoke public Object intercept( final InvocationContext i) throws Exception { // do someting with foo service return i.proceed(); } The question is: Will a Java EE 5 compliant application server (e.g. JBoss 5) inject into the interceptor? If no, what is good strategy for accessing the session bean? To consider: Deployment ordering / race conditions

  • Deploying spring message driven pojo on weblogic 8.1

    - by Igman
    Hello, I am trying to deploy a spring message message driven POJO on weblogic 8.1. It is a simple POJO, and it works fine being run outside of an application server, but the messages do not seem to be picked up at all. I have created empty home and remote interfaces, as well as a container bean class that contains an instance of the pojo which it gets from the application context. I then added this container bean class to the ejb-jar.xml as a . I have not been able to get the messages pick up. Does anyone have any suggestions as to what I am doing wrong? Could anyone point me to a tutorial on how to deploy a MDP? Thanks.

  • Most Efficient Way of calling an external webservice in Java?

    - by Sudheer
    In one of our applications we need to call the Yahoo Soap Webservice to Get Weather and other related info. I used the wsdl2java tool from axis1.4 and generated th required stubs and wrote a client. I use jsp's use bean to include the client bean and call methods defined in the client which call the yahoo webservice inturn. Now the problem: When users make calls to the jsp the response time of the webservice differs greatly, like for one user it took less then 10 seconds and the other in the same network took more than a minute. I was just wondering if Axis1.4 queues the requests even though the jsps are multithreaded. And finally is there an efficient way of calling the webservice(Yahoo weather). Typically i get around 200 simultaneous requests from my users.

  • Spring webflow 1.0 - Downloading a file

    - by Dave
    I am using spring webflow 1.0. I am uploading a csv file, parsing it, and displying results before proceeding. The user has an option to download a csv file that contains the records that did not pass validation. When I click the link in a JSP to download this file, webflow invokes a form Action. The form action writes out a file via getting the output stream off the response: HttpServletResponse response = ((ServletExternalContext) context.getExternalContext()).getResponse(); I do not want to leave the jsp I'm currently on. I just want to download the file. In other words, I do not want to transition to another state. I just want to serve the dynamically rendered file. Everything works (I don't leave the page, and I download the file), but I'm getting the following error in my console: _pEncydKfggPHJo8=org.springframework.webflow.engine.NoMatchingTransitionException: No transition was matched on the event(s) signaled by the [1] action(s) that executed in this action state 'downloadErrorReportAction' of flow 'myFlow'; transitions must be defined to handle action result outcomes -- possible flow configuration error?

  • Richfaces a4j achtionparam set null value

    - by Jurgen H
    I am trying to reset some values in a form using the a4j:actionParam tag. But it seams that null values never arrive in the target bean. The converter receives it correctly, returns null, but it is never set in the bean. The target is to fill in the start and endDate for different predefined values (last week, last month etc). For the "This week" value, the endDate must be reset to null. <rich:menuItem value="Last week"> <a4j:support event="onclick" reRender="criteriaStartCalendar,criteriaEndCalendar"> <a4j:actionparam name="startDate" value="#{dateBean.lastWeekStart}" assignTo="#{targetBean.startDate}" /> <a4j:actionparam name="endDate" value="#{dateBean.lastWeekEnd}" assignTo="#{targetBean.endDate}" /> </a4j:support> </rich:menuItem>

  • Accessing the value of a Richfaces calendar during validation.

    - by JBristow
    I am trying to validate a field based on another field's value. <h:form id="item"> <s:validateAll/> <h:selectBooleanCheckbox id="selected" value="#{bean.selected}" validator="selectedValidator"/> <rich:calendar id="startDate" value="#{bean.startDate}"/> </h:form> However, inside my validator. public void validate(FacesContext context, UIComponent component, Object value) throws ValidatorException { UIInput startComp = (UIInput) context.getViewRoot().findComponent("item:startDate"); if(value != null && value) { // Check value of startComp and throw exception if null or empty. } } The component startComp resolves, but has no value. Where is the value that appears in the text box of the richfaces calendar component?

  • JSF hiding exceptions?

    - by bshacklett
    I have a managed bean for a JSF page which is doing JPA calls in the constructor to populate fields in the bean. I'm having a bit of trouble with another call to persist an entity (to populate data for testing). I'm expecting it to throw some sort of exception since it's not working, but I'm not getting anything. Just of the heck of it I tried the following: Query newQuery = em.createQuery("Bad Syntax"); List newList = newQuery.getResultList(); I'd expect an IllegalArgumentException here since the query string is completely invalid, but the page still loads and I don't see any exceptions anywhere. Am I right in expecting this exception? If so, why am I not seeing it?

  • Spring struts and forms

    - by Kiva
    Hi guy, I need to integrate struts with spring for a project. I read the doc to ingrate struts and it's ok for classic beans but I have a problem for my forms. I have a form like this in my struts-config.xml: <form-beans> <form-bean name="creationForm" type="org.apache.struts.validator.DynaValidatorActionForm" > <form-property name="libelle" type="java.lang.String" /> <form-property name="quantite" type="java.lang.String" /> <form-property name="prix" type="java.lang.String" initial="10" /> </form-bean> But it's strange for me to have a "type" in struts-config because it's spring which manages beans. I don't found anything in the doc to manage forms by spring and the attribute "type" is mandatory for form in struts-config. Someone can help me please ?

  • JSR-303 dependency injection and Hibernate

    - by Jam
    Spring 3.0.2, Hibernate 3.5.0, Hibernate-Validator 4.0.2.GA I am trying to inject Spring dependencies into a ConstraintValidator using: @PersistenceContext private EntityManager entityManager; I have configured the application context with: <bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean"/> Which, according to the Spring documentation, should allow “custom ConstraintValidators to benefit from dependency injection like any other Spring bean” Within the debugger I can see Spring calling getBean to create the ConstraintValidator. Later when flush triggers the preInsert, a different ConstraintValidator is created and called. The problem is the EntityManager is null within this new ConstraintValidator. I’ve tried injecting other dependencies within the ConstraintValidator and these are always null. Does anyone know if it is possible to inject dependencies into a ConstraintValidator?

  • a4j:support within a rich:modalPanel

    - by Andy Deighton
    Hi all, I've hit a wall. I know the a4j and rich tags pretty well (I use Seam 2.2.0 and Richfaces 3.3.1). However, I'm trying to do something quite simple, but in a rich:modalPanel. It seems that rich:modalPanels do not allow Ajax events to be fired. Here's a simple breakdown: I have a h:selectOneMenu with some items in it and whose value is attached to a backing bean. Attached to that h:selectOneMenu is a a4j:support tag so that whenever the change event is fired, the backing bean should get updated. Truly simple stuff eh? However, when this h:selectOneMenu is in a rich:modalPanel the onchange event doesn't update the backing bean until the rich:modalPanel closes. I can confirm this because I'm running it in Eclipse debug mode and I have a breakpoint on the setter of the property that's hooked up to the h:selectOneMenu. This is driving me mad! This is vanilla stuff for Ajax, but rich:modalPanels don't seem to allow it. So, the question is: can I do Ajax stuff within a rich:modalPanel? I'm basically trying to use the rich:modalPanel as a form (I've tried a4j:form and h:form to no avail) that reacts to changes to the drop down (e.g. when the user changes the drop down, a certain part of the form should get reRendered). Am I trying to do something that's not possible? Here's a simplified version of the modalPanel: <rich:modalPanel id="quickAddPanel"> <div> <a4j:form id="quickAddPaymentForm" ajaxSubmit="true"> <s:decorate id="paymentTypeDecorator"> <a4j:region> <h:selectOneMenu id="paymentType" required="true" value="#{backingBean.paymentType}" tabindex="1"> <s:selectItems label="#{type.description}" noSelectionLabel="Please select..." value="#{incomingPaymentTypes}" var="type"/> <s:convertEnum/> <a4j:support ajaxSingle="true" event="onchange" eventsQueue="paymentQueue" immediate="true" limitToList="true" reRender="paymentTypeDecorator, paymentDetailsOutputPanel, quickAddPaymentForm"/> </h:selectOneMenu> </a4j:region> </s:decorate> </fieldset> <fieldset class="standard-form"> <div class="form-title">Payment details</div> <a4j:outputPanel id="paymentDetailsOutputPanel"> <h:outputText value="This should change whenever dropdown changes: #{backingBean.paymentType}"/> </a4j:outputPanel> </fieldset> </a4j:form> </div> </rich:modalPanel> Regards, Andy

  • What is a right way to use servlets?

    - by vikp
    Hi, I'm studying EJB3. I have a session bean which provides services to create/update customer accounts. This session bean offers services on the lines of: public void addCustomer(Customer c); public void updateCustomer(Customer c); Ideally I'd like to have a single servlet: CustomerServlet and it would invoke the session beans that I have listed above. Problem is that I have two JSPs: UpdateAccount.jsp and CreateAccount.jsp. Both of these JSPs have a form with a method POST and action "CustomerServlet". How can I distinguish in a customer servlet which operation I should carry out: createAccount or updateAccount? I guess the alternative is to have a separate servlet for each operation... Thank you

  • Deploying Multiple Environments in Spring-MVC

    - by jboyd
    Currently all web apps are deployed using seperate config files: <!-- <import bean.... production/> --> <import bean... development/> This has disadvantages, even if you only need to swap out one config file, that I'm sure everyone is familiar with (wondering what just deployed without searching through XML is one of them) I want to add Logging to my application that basically says 'RUNNING IN PRODUCTION MODE', with a description of the services deployed and what mode they are working in. RUNNING IN PRODUCTION MODE Client Service - Production Messaging Service - Local and so on... Is this possible in Spring using a conventional deployment (putting a war on a server)? What other things do people do to manage deployments and software configurations? If not, what other ways could you achieve something similar?

  • hasErrors with indexed property

    I am having hard time getting hasErrors to work with indexed properties. For example class Order { String prop1 String prop2 static hasMany = [items: Item] } class Item { String name static constraints = { name(blank:false) } } Validation works properly and on item.name being blank I do get an error with <g:renderErrors bean="${orderInstance}"/> However, I am trying to have input box highlighted using hasErrors : <g:each in="${orderIntsance.items}" status="i" var="item"> <span class="field ${hasErrors(bean: orderInstance, field: ????????? , 'errors')}"> <g:textField name="items[${i}].name" value="${item?.name}"/> </span> </g:each> Not sure how to get to it with a field: property, any ideas? Thanks

  • EJB3.1 Remote invocation - is it distributed automatically? is it expensive?

    - by Hank
    I'm building a JEE6 application with performance and scalability in the forefront of my mind. Business logic and JPA2-facade is held in stateless session beans (EJB3.1). As of right now, the SLSBs implement only @Remote-interfaces. When a bean needs to access another bean, it does so via RMI. My reasoning behind this is the assumption that, once the application runs on a bunch of clustered application servers, the RMI-part allows the execution to be distributed across the whole cluster automagically. Is that a correct assumption? I'm fine with dealing with the downsides of that (objects lose entityManager session, pass-by-value), at least I think so. But I am wondering if constant remote invocation isn't adding more load then necessary.

  • JSF actionListener is called multiple times from within HtmlTable

    - by Rose
    I have a mix of columns in my htmltable: 1 column is an actionlistener, 2 columns are actions and other columns are simple output. <h:dataTable styleClass="table" id="orderTable" value="#{table.dataModel}" var="anOrder" binding="#{table.dataTable}" rows="#{table.rows}" <an:listenerColumn backingBean="${orderEntry}" entity="${anOrder}" actionListener="closeOrder"/ <an:column label="#{msg.hdr_orderStatus}" entity="#{anOrder}" propertyName="orderStatus" / <an:actionColumn backingBean="${orderEntry}" entity="${anOrder}" action="editOrder" / <an:actionColumn backingBean="${orderEntry}" entity="${anOrder}" action="viewOrder"/ .... I'm using custom tags, but it's the same behavior if I use the default column tags. I've noticed a very strange effect: when clicking the actionlistenercolumn, the actionevent is handled 3 times. If I remove the 2 action columns then the actionevent is handled only once. The managed bean has sessionscope, bean method: public void closeOrder(ActionEvent event) { OrdersDto order; if ((order = orderRow()) == null) { return; } System.out.println("closeOrder() 1 "); orderManager.closeOrder(); System.out.println("closeOrder() 2 "); } the console prints the'debug' text 3 times.

  • How to Generate Edifact message from a xml ?

    - by Clem
    Hello, I'm currently dealing with customs messages Beans in Java. After filling in the Beans with different values, I want to produce an EDIFACT CUSDEC message corresponding to each message. For each attribute of a message Bean, I have the information to put the attribute in the right place in EDIFACT CUSEDC format. Thus, I am looking for a free tool (a Java API) which could ideally convert my full-filled Bean into an EDIFACT CUSDEC message. I found a commercial solution (not free) there : http://www.datadirect.com/products/edifact-grid/index.ssp And a quick tutorial here : http://biemond.blogspot.com/2008/09/generate-edifact-message-from-xml.html But ... unfortunately it is not free.. Thanks in advance for your help!

  • simple EJB jar deployed in jboss with its own log4j configuration

    - by user309281
    Hi All I have a simple EJB jar with a stateless session bean, deployed in JBOSS AS 4.2.2, unde r/server/default/deploy. The bean is registered under JNDI tree as viewed from jboss jmx console and I am able to access it through a remote java client outside JBOSS. Inside EJB jar, I have added some logging to be written to a separate log file, using apache log4j jar and log4j.xml. But I am not able to view any of the logs. Also I do not wish to use jboss-log4j.xml, since there will be many other EJBs to be deployed and wish to have separate log4j for each EJB application. Here is my one of the EJB-jar contents: EJB_DS.jar: log4j.xml classes apache log4j jar is added to /server/default/lib path. Kindly highlight if i have missed any points for enabling log4j configuration With Regards, Krishna
