RFC 目标不存在

RFC Destination does not exist

我正在尝试使用 Neo Cloud SDK 3.54.23 在 Tomcat 8.5 中配置应用程序 运行ning 以连接到 RFC 目标和 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,但其中 none 行得通。

我试过设置 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

我尝试创建一个以 .jcoDestination 结尾的文件并设置 属性 -Djco.destinations.dir=/home/cassio/jco-destinations 但其中 none 有效。

我总是得到:

如何使用适用于 Eclipse 的 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?

我发现了我认为的解决方法。

如果我只是在 Eclipse 中的服务器配置上设置目标,SDK 会找到目标名称但找不到配置。

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

而且我还必须创建 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

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

通过这两个配置,我能够让 SDK 识别端点名称及其配置。然后我能够使用该服务以及通过 BapiQuery.

调用其他 BAPI
