Since we're on the topic of WOAdaptors, if anyone knows how to properly handle streaming multipart requests in a WOAdaptor, I'll be a very happy man.
I wrote an experimental Jetty-based WOAdaptor a while back (I also want WebSockets) — but I wasn't able to get it to handle streaming mulitpart uploads. When handling those, WONoCopyPushbackInputStream.read() complains about "Amount read didn't match content-length". Pretty sure I'm passing in a proper data stream and length since I can read the data and consume other streaming requests just fine — just won't work when multipart parsing is involved. https://github.com/undur/wo-jetty-adaptor/blob/048928a4878d3db8c2d7014fe47afcc39887e3b6/src/main/java/com/webobjects/appserver/WOAdaptorJetty.java#L203-L214 Unfortunately it seems the Netty adaptor loads the entire request data into memory before handling the request, if I'm understanding this correctly, so no help there :-/ https://github.com/wocommunity/wonder/blob/53e84729120a3a6cdf4bf793a963c670da2d8493/Frameworks/WOAdaptors/ERWOAdaptor/Sources/er/woadaptor/ERWOAdaptorUtilities.java#L45 -- Unrelated; if you're thinking of writing an adaptor I wrote a an adaptor using Java's built in HTTP server to ensure the multipart thing wasn't a Jetty problem. It's a nice way to see the very basics of writing a WOAdaptor I think (with the caveat that I'm really no WOAdaptor expert :). It has the same problem with streaming multiparts though. https://github.com/undur/wonder-slim/blob/9cc6a793555d55f4465d45b33ce8f7be9c432799/ERExtensions/src/main/java/com/webobjects/appserver/WOAdaptorPlain.java#L35 Cheers, - hugi > On 11 Nov 2025, at 09:12, Ramsey Gurley <[email protected]> wrote: > > I would not be surprised if that WOAdaptor needs a lot of work.
