RFC目标不存在

我尝试使用Neo Cloud SDK 3.54.23配置在Tomcat 8.5中运行的应用程序，以连接到RFC目标并运行以下代码：

String destinationName = "RFCQueryEndpoint";
ErpConfigContext erpConfigContext = new ErpConfigContext(destinationName);
ErpEndpoint endpoint = new ErpEndpoint(erpConfigContext);
response.getWriter().write(new Gson().toJson(new
             DefaultFinancialTransactionService().getList()
             .execute(endpoint).getListOfSelectedTransactions()));

我尝试了多种配置RFC目标的方法，但都没有。

我尝试使用以下内容设置destinations环境变量

[{name: "RFCQueryEndpoint", type: "RFC", jco.client.ashost: "host-here", jco.client.client: "100", jco.client.lang: "EN", jco.client.passwd: "pass-here", jco.client.sysnr: "01", jco.client.user: "user-here"}]

我已尝试在服务器配置中配置目标，如https://help.sap.com/viewer/cca91383641e40ffbe03bdc78f00f681/Cloud/en-US/7fa92ffa007346f58491999361928303.html

中所述

我尝试创建一个.jcoDestination结尾的文件，并设置属性-Djco.destinations.dir=/home/cassio/jco-destinations，但没有一个工作。

我总是得到：

如何使用SAP SAP工具在本地正确配置RFC目标，以使用Neo Cloud SDK + Tomcat连接到S / 4 Hana On-Prem系统？

1 个答案:

答案 0 :(得分：7)

我发现我认为是一种解决方法。

如果我只是在Eclipse中的服务器配置上设置目标，则SDK会找到目标名称，但无法找到配置。

我必须在服务器配置页面中设置目的地，如下所述：https://help.sap.com/viewer/cca91383641e40ffbe03bdc78f00f681/Cloud/en-US/7fa92ffa007346f58491999361928303.html

我还必须创建RFCendpoint.jcoDestination文件，如下所示：

Name=RFCendpoint
Type=RFC
jco.client.client=100
jco.client.lang=EN
jco.client.user=User-here
jco.client.passwd=Password-here
jco.client.ashost=Host-here
jco.client.sysnr=00
jco.destination.pool_capacity=5
jco.destination.peak_limit=10

并通过Eclipse中-Djco.destinations.dir=/home/cassio/jco-destinations的参数部分中的Run configuration标志传递文件所在的目录。

通过这两种配置，我能够获得SDK来重新定义端点名称及其配置。然后我就可以使用该服务以及通过BapiQuery调用其他BAPI。
