从 CodeNameOne 访问网页

Question

我正在尝试从 CodeNameOne 应用程序访问网页。奇怪的是，模拟器抛出错误，而应用程序在安卓手机中运行良好。

代码片段：

表单 loginForm = new Form("LoginNew"); loginForm.setLayout（新 边框布局（））； WebBrowser 浏览器 = 新的 WebBrowser() browser.setURL("http://mobile.apps-tek.com:8081/apps-webservices"); loginForm.addComponent(BorderLayout.CENTER,browser); loginForm.show();

在模拟器中运行时出错。

您似乎正在使用配置为不支持 Java FX 的 Java 6 或 Java 7。在没有 Java FX Codename One 的情况下运行时，默认使用功能手机 Web 浏览器组件，这非常有限且存在问题。

确保用于运行 Codename One 的 VM 是 Java SE 7，并且其中包含其他 Java FX 库。
