Issue/Introduction

We have a standalone APM 10.7 SP3 environment. When starting the WebView, we get an error:

APM WebView could not be started

We have tried to clear the cache on both EM and WV, also checked ownership and permissions and all seem to be good. This issue started after applying the SP3. We tested before the SP3 (10.7 0000) all was working fine.

Based on our investigation, we see that a possible cause could be related to the webview-jetty-config.xml file. We are using HTTPS. HTTPS was works good before the SP3.

We see following error in IntroscopeWebViewConsole.log:

[ERROR] [WebServer] Error loading ./config/webview-jetty-config.xml

Environment

Release : 10.7.0

Component : APMISP

Resolution

It appears that the webview-jetty-config.xml file in this environment may be corrupt. We upgraded an environment from APM 10.7 0000 to APM 10.7 SP3, and we did not observe this issue. HTTPS is working good in both environments (APM 10.7 0000 and APM 10.7 SP3). Please use the attached webview-jetty-config.xml file which is from APM 10.7 SP3 environment (This is a default webview-jetty-config.xml file with no changes).
