JAX-WS: Async client outbound max connection settings

[BerksanAtes]

In traditional WebSphere Application Server (tWAS), the com.ibm.websphere.webservices.http.maxConnection property limits client outbound connections. Apache CXF provides equivalent functionality through the following properties:

• org.apache.cxf.transport.http.async.MAX_CONNECTIONS - Maximum total connections across all hosts
• org.apache.cxf.transport.http.async.MAX_PER_HOST_CONNECTIONS - Maximum connections per individual host

or asynchronous connections, the org.apache.cxf.transport.http.async.usePolicy property is not required because CXF defaults to ASYNC mode. Simply configure the connection limits in your jvm.options file:

-Dorg.apache.cxf.transport.http.async.MAX_CONNECTIONS=<Number of connections>
-Dorg.apache.cxf.transport.http.async.MAX_PER_HOST_CONNECTIONS=<Number of connections>

For synchronous connections, you must explicitly set the usePolicy property to ALWAYS in addition to the connection limits:

-Dorg.apache.cxf.transport.http.async.usePolicy=ALWAYS
-Dorg.apache.cxf.transport.http.async.MAX_CONNECTIONS=<Number of connections>
-Dorg.apache.cxf.transport.http.async.MAX_PER_HOST_CONNECTIONS=<Number of connections>
