Servlet container

VirtualViewer HTML5 for Java requires a J2SE or J2EE servlet container to run. We recommended the Apache Tomcat and IBM Websphere application servers.

Other servlet containers such as Weblogic or Jboss may be optionally supported. Please contact Snowbound for detailed support information for these and any other special-case systems.

Server Java version

VirtualViewer HTML5 for Java JRE of 1.8 or higher is highly recommended, though JRE 1.7 will be supported through 2019.

NOTE: We have upgraded to JDK11 starting with VirtualViewer 5.3.0.

Client browser versions

We recommend Firefox, Google Chrome, Microsoft Edge, and Safari for client browser use.

Internet Explorer 11 can be used in most circumstances, but due to age, incompatibility and lower performance, it is not recommended. VirtualViewer may also work with other browsers (such as Opera), but no testing is done to ensure compatibility or performance.

Note If you are using Internet Explorer 11, VirtualViewer will look, perform, and behave better if it is running outside of compatibility mode. For best performance, please configure Internet Explorer to use normal mode when using VirtualViewer. Quirks mode in Internet Explorer is not supported.

Exceptions to Supported File Formats and Platforms

We do our best to support product and document specifications and to work in common platform environments, however there are always exceptions.

If you discover an exception or issue, please contact Snowbound Support at support.snowbound.com to let us know about it.
