由 心不动则不痛 提交于 2019-12-14 03:46:21
问题 Please I would like to know the major difference between a Jave EE project and a Java Web project in netbeans IDE with respect to the EJB . In fact you can create a web application based on EJB , JPA and JavaServer Faces in Netbeans IDE if you choose the Java Web category . On the other hand you choose the project category as Jave EE project , NetBeans IDE will create 3 sub-projects, e.g: StoreApp (Enterprise Application project), StoreApp-ejb (EJB project), and StoreApp-war (Web project).

问题 I'm looking for any kind of software which allows me to generate, in an automatically way, the MVC files (a bean and a xhtml view) of any CRUD of any entity using Java Server Faces 2 and Richfaces 4 technologies.

I search but I didn't find any documentation about it. Do you know which is the best solution for

Conditional invocation of rich:popup panel

由 扶醉桌前 提交于 2019-12-14 03:19:52
问题 Hello Everyone I would like to open a rich:popupPanel inside a conditional expression, actually what I'm trying is something like this: onclick="#{searchBackingBean.showLoginPanel==true ? #{rich:component('loginPopup')}.show();':''}" However I'm getting errors related to EL, how should I write this correctly?.

Export to Excel using JSF 2 and XSLT

由 為{幸葍}努か 提交于 2019-12-14 03:03:31
问题 We used Java 5, Tomcat 5, Xalan, and JSF 1 to build an application that used XSLT, XML, and a Tomcat Filter to enable users to export their data in Excel format. We recently upgraded to Java 1.7.0_07, Tomcat 7.022 and JSF 2.1 (jsf-api-2.1.0-b03.jar). Due to the effort involved we have not yet upgraded to facelets; we still use jsp's. We use an tag to display the Excel report in its own popup window. The problem is that after the upgrade the popup is now displaying raw xml in IE, rather than
