These functions are usually saved in utility or helper classes so they can be reused. JVx also uses various utility classes, which can be found in the package com.sibvisions.util. text/html 2020-06-15T12:59:34+00:00 http://doc.sibvisions.com/jvx/common/util/csv_export?rev=1592225974&do=diff If you need a CSV export of a databook, there's already a built-in solution in JVx. Of course, it depends on your databook implementation, whether it's a RemoteDataBook or a MemDataBook, or completely different. But usually, the following snippet will help: text/html 2018-02-02T09:44:18+00:00 http://doc.sibvisions.com/jvx/common/util/httpcontext?rev=1517564658&do=diff The com.sibvisions.rad.server.http.HttpContext is useful for application server deployments. It allows accessing the original request and response from the http connection. If you need access to the HttpRequest, HttpResponse, PortletReqeust or PortletResponse, simply use the HttpContext. text/html 2020-06-15T14:40:43+00:00 http://doc.sibvisions.com/jvx/common/util/log4j?rev=1592232043&do=diff If you want to use log4j or log4j2 instead of standard Java logging API for your application, simply add the logger factory configuration to your classpath. First, create a file with the name loggerfactory.properties in one of your source/resource directories. Don't use a package name! text/html 2024-11-18T10:35:28+00:00 http://doc.sibvisions.com/jvx/common/util/loggerfactory?rev=1731926128&do=diff Without log mechanisms, software development is a lot more arduous than it needs to be. For this reason, a log mechanism is included in JVx. The following methods are provided via UIComponent: public void info(Object... pInfo) public void debug(Object... pInfo) public void error(Object... pInfo) text/html 2020-06-29T13:44:22+00:00 http://doc.sibvisions.com/jvx/common/util/os_detection?rev=1593438262&do=diff If you want to know the current operating system, simply use a utility method: com.sibvisions.rad.ui.ApplicationUtil.isMacOS(); com.sibvisions.rad.ui.ApplicationUtil.isLinux(); com.sibvisions.rad.ui.ApplicationUtil.isWindows(); text/html 2020-07-28T09:52:30+00:00 http://doc.sibvisions.com/jvx/common/util/reflective?rev=1595929950&do=diff JVx's reflective class allows you to create class instances or call methods via reflection but without directly using java.lang.reflect. How does it work? We have a short example for you. Our class: package com.sibvisions.app; public class MyClient { public Result doUpload(String pKey, String pValue) { ... } public Result doDownload(String pPath) { ... } public Result doDownload(File pFile) { ... } } text/html 2022-11-17T11:13:11+00:00 http://doc.sibvisions.com/jvx/common/util/rest?rev=1668683591&do=diff We define the business logic with life cycle objects on the server side. The access authorization of an application is checked by a security manager. The business logic is usually available via master- or subconnections from the client. In order to complete the technology independence, the complete business logic of an application is also available via REST. text/html 2020-06-15T14:38:47+00:00 http://doc.sibvisions.com/jvx/common/util/servercontext?rev=1592231927&do=diff The ServerContext is a special context for server-side objects. If you create your own plugins or extend the server, session manager, object provider or a server class, it can useful to have access to the affected session.

Firstly, you have to start a Vert.x server (HttpServer or NetServer). We provide a simple class that starts a server and automatically uses JVx: Simply execute (use ; instead of : on windows): text/html 2020-06-29T14:52:24+00:00 http://doc.sibvisions.com/jvx/common/util/xml?rev=1593442344&do=diff If you work with XML files, it's not too easy to use the right parser because there are many of them and, if you want a simple parser without writing a lot of source code, you need some luck. We added two classes to JVx that solves simple XML handling.
