Can you debug into Synapse and see why the API context does not get removed
from the path in the first case? That's how it's supposed to work. From the
API class:
if (restURLPostfix.startsWith(context)) {
restURLPostfix = restURLPostfix.substring(context.length());
if (versionStrategy instanceof URLBasedVersionStrategy) {
String version = versionStrategy.getVersion();
if (restURLPostfix.startsWith(version)) {
restURLPostfix =
restURLPostfix.substring(version.length());
} else if (restURLPostfix.startsWith("/" + version)) {
restURLPostfix =
restURLPostfix.substring(version.length() + 1);
}
}
((Axis2MessageContext)
synCtx).getAxis2MessageContext().setProperty(
NhttpConstants.REST_URL_POSTFIX, restURLPostfix);
}
Thanks,
Hiranya
