Unable to login to WebView after applying 10.8 SP2

Products

• CA Application Performance Management (APM / Wily / Introscope)

Issue/Introduction

I could not get to WebView, received connection refused. Although the WebView JVM had started up, and had appeared to start properly.

I was able to login via the Workstation client and perform an environment health check.

 

IntroscopeWebView.log contain something like the following

2026-01-08 16:20:20.551  INFO 8992 --- [WrapperSimpleAppMain] WebServer : Configuring the Jetty web server from configuration file: C:\Program Files\CA APM\Introscope10.8.0.27\.\config\webview-jetty-config.xml

org.xml.sax.SAXParseException: cvc-elt.1.a: Cannot find the declaration of element 'Configure'.

Resolution

The webview-jetty-config.xml is missing the declaration line

<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure_9_3.dtd">

 

To resolve the issue:

1) Edit APM-HOME\config\webview-jetty-config.xml

2) Add the declaration line after version line 

<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure_9_3.dtd">

<!-- =============================================================== -->
<!-- Configure the embedded Jetty Server in the Webview              -->
<!-- =============================================================== -->

 

3) Restart WebView service
