Hi Short question: How can I prevent tomcat to receive the complete post data? Stop sending the data before it's all been sent. Sorry, I don't understand what you mean. If you mean to send only small parts and only those that are wanted, that's nothing I can do. I need to support the

WebSockets and HTTPS problems

Hi We have a web application that makes more and more use of websockets. (In fact we emulate websockets with comet servlets for older browsers and want to use real websockets for current ones.) We implemented our websocket support using tomcat 7.0.30 and a servlet extending

AW: AW: WebSockets and HTTPS problems

Hi I just took a look at this. The examples work out of the box for HTTPS with BIO but not with NIO. This looks like a Tomcat bug at this point. I'll take a look. What would I need to do to switch to BIO for now? And does Comet work with BIO? Regards, Steffen smime.p7s Description:

Sending through WebSockets

Configure connectors while running tomcat from webapp

Hi Currently I need to find a way to replace the ssl certificate used by a (nio) connector at runtime. It also needs to be done by the (only) webapp. Is there a way to do this? Soon we will need a way to change the ip address a connector is listening on. Both could be solved by removing a

Small bug in Tomcat and interest in wildcard patch

Hi I looked into the source of tomcat 7 (7.0.x trunk) to extend it to support wildcard aliases (such as *.example.com). I found the class org.apache.tomcat.util.http.mapper.Mapper. Looking at it, I found a small bug (lines 210-213): if (pos 0) { log.error(No host found: +

AW: Adding Connectors

Hi I think this should be discussed on the users' list. I'm cross-posting this message one time for that purpose. See below. Sorry, as I assumed that in a state where tomcat does not start connectors defined in server.xml it should also not start other connectors, I regarded this as a bug.

Choosing provider to load pkcs12 keystore for ssl

Hi I am using tomcat with the NIO connector, so I load the ssl certificate and private key from a keystore in pkcs12 format. This works fine using RSA. Now I want to switch to a certificate using ECC and that EC is not supported by the JRE. It IS however supported by bouncycastle. In my own

AW: Choosing provider to load pkcs12 keystore for ssl

Hi Okay, I must have overlooked the keystoreProvider attribute completely. Sorry for that and thanks a lot for the hint. However that only solved the loading part of the problem. The certificate is still unusable. When I try to connect, the browser reports an error. I set javax.net.debug=all

Forcing SSL Renotiation

Hi My tomcat installation offers pages through https only. So when accessing these pages, an ssl connection is established. Later on, a user may decide to log in, hence hitting a page, that requires client certificates, and the browser pops up a selection dialog for a certificate. Once

How to configure a TrustManager in code?

URI Templates

Hi I have several servlets with mappings such as /a/* /b/* /c/* And so on. One of these mappings was for the old Tomcat 7.0.27 websocket implementation: /ws/* That worked. Now, with the new JSR version in Tomcat 8, I cannot get this to work. The problem is, that all of the following

Connection resets without timeout
