从Java调用SSJS? [英] Calling SSJS from Java?

问题描述

我创建了一个xPages应用程序，该应用程序使用位于服务器端javascript库中的许多服务器端javascript代码功能.

I have created an xPages application which uses a lot of server side javascript code functions located in a server side javascript library.

现在，我有一些Java代码位于java设计元素中，我想使用它们来调用javascript函数.

Now I have some java code located in the java design element which I would like to use to call the javascript functions.

我确实知道从Java调用javascript是不合逻辑的，但是我想所有服务器端javascript都已编译为Java，因此我认为可能可以获取已编译Java类的句柄.生成.

I do understand that it is not logical to call javascript from java, but I guess that all server side javascript is compiled to java, so I was thinking that it might be possible to get a handle to the compiled java class that was generated.

有什么想法吗?

推荐答案

您可以创建值绑定，

ValueBinding vb = FacesContext.getCurrentInstance().getApplication().createValueBinding("#{javascript:getData()}");
System.out.println(vb.getValue(FacesContext.getCurrentInstance()).toString());

这将从您的SSJS库中调用 getData()方法.

This would call the getData() method from your SSJS library.
