[wildfly-dev] question 2 sec boot time of WISE

[Brian Stansberry]

What you are doing in wise-sandbox is different from what would be involved with adding a context to the management interface. It’s integrating using the WebHost concept, which then brings in EE related APIs (servlets etc.)

For what you’re doing to be proper, undertow would need to agree to expose WebHost as a proper capability and agree to support the entire API as a reliable contract.

To integrate with the management interface we’d need to develop a different contract.
