作为Web服务运行的Java应用程序与Glassfish上的Java EE应用程序进行通信

[英]Java Application running as web service communicating with Java EE app on Glassfish

原文 2013-07-10 22:36:24 2 2 java/ web-services/ glassfish/ glassfish-3

I have a stand alone Java application that needs to get information (string data) from a Java EE application, running on a Glassfish 3.1 Application server. 我有一个独立的Java应用程序，需要从运行在Glassfish 3.1 Application服务器上的Java EE应用程序获取信息（字符串数据）。 I have created a web service for my Java app, but I'm wondering how I could achieve communication with the Java EE glass fish app (using servlet?). 我已经为我的Java应用程序创建了一个Web服务，但是我想知道如何实现与Java EE glass fish应用程序的通信（使用servlet？）。

I hope to have a method on my app that can be called from, for example, a client running on glassfish (and vice-versa). 我希望在我的应用程序中有一个方法，可以从运行在glassfish上的客户端调用该方法（反之亦然）。 This method would have something like a String array as parameter, so that I would be able to pass the data between the apps. 此方法将具有类似String数组的参数，这样我就可以在应用程序之间传递数据。

Note : I am unable to deploy my app on Glassfish, since we are trying to achieve separation till we are sure the application I am developing will not cause Glassfish to crash ( we currently have other critical apps running on Glassfish). 注意：我无法在Glassfish上部署我的应用程序，因为我们试图实现分离，直到我们确定正在开发的应用程序不会导致Glassfish崩溃（我们目前在Glassfish上运行其他重要的应用程序）。 Also note that this is all taking place on the same machine. 另请注意，这都是在同一台计算机上进行的。

You should develop a web service and deploy it on Glassfish within your existing application. 您应该开发一个Web服务并将其部署在现有应用程序中的Glassfish上。 You can do this via a Servlet based web service, or a Session Bean web service, whichever is more appropriate for you. 您可以通过基于Servlet的Web服务或Session Bean Web服务（两者中最合适的一个）来执行此操作。

You will then create a web service client against that web service for your Java app, and integrate it appropriately with calls to the servers via the web service. 然后，您将针对Java应用程序针对该Web服务创建一个Web服务客户端，并将其与通过Web服务对服务器的调用适当地集成。

Of course, this should all be done against development servers, not your production servers. 当然，所有这些操作都应针对开发服务器而不是生产服务器。 Glassfish can be deployed pretty much anywhere: your machine, another machine, a VM, in "the cloud". Glassfish几乎可以部署在任何地方：“云”中的计算机，另一台计算机，VM。 Not having a development server available for, well, development is unacceptable . 没有开发服务器可用于开发，这是不可接受的 。 There is no way you can determine if your app will "crash Glassfish" unless you can test it. 除非您可以对其进行测试，否则无法确定您的应用程序是否会使“ Glassfish”崩溃。
