External Web Service Proxy Configuration for Visual Composer

[Former Member]

Introduction

To use external web services within the SAP NetWeaver 2004s platform, you will need to setup the http proxy to be able to access these web services. This blog will show you how to setup the web service proxies. Keep in mind this has changed between SP8 and SP9 within SAP NetWeaver 2004s.

How do I set it up within SPS8 and lower?

Within SPS8 and lower, the proxy configuration for web services that are used in Visual Composer are specified through "System Administration -> System Configuration -> Service Configuration -> Applications -> com.sap.portal.ivs.httpservice -> Services -> Proxy". For details on this see the online help at: Configuring Proxy Settings.

Figure 1.2 - Specify HTTP(s) proxy configuration

How do I set it up within SPS9 and higher?

Within SPS9 and higher, proxy configuration for web services has been moved to the Visual Administrator. Within the Visual Administrator, navigate to "Server # -> Services -> Web Services Container -> Runtime -> Settings". Set the proxy information here. This is described in the online help here: Configuring Proxy Settings.

What types of web services are currently supported?

Web Services are handled differently between SPS8 and SPS9 within the NetWeaver stack.

Within SPS8, see OSS Note 936768 for an explanation of the supported structure types.

As of SPS9, Visual Composer supports Web services that are compliant with the Basic Profile 1 standard of the Web Services Interoperability (WS-I) Organization. Consistent use of WS-I compliant Web services will ensure technology-independent operability across platforms, operating systems and programming languages. This is mentioned in the release notes for Visual Composer in SPS9 here: http://help.sap.com/saphelp_nw2004s/helpdata/en/77/3f89af68304e2090d34f60506fd90c/frameset.htm. This is also mentioned in OSS Note 969418.

Summary

The reason I put this together was due to the numerous questions around web service consumption within Visual Composer. Hope this helps!
