RE: Using QPID behind HTTP proxy

Thanks for the reply ;) I have read into the AMQP over WebSockets specs. However it seems that it only supports AMQP 1.0 right? I am using the c++ messaging API which (I think) only supports 0-9? Anyhow, it would require me to manually send the AMQP commands using websockets right? I was

Using QPID behind HTTP proxy

Hello, in my c++ application several computations are performed on a remote server. I have implemented this using QPID and everything works fine if a direct internet connection is available. However, some of my clients use a HTTP proxy to access the internet. Is there any possibility to tell QPID

Re: Max Frame Size for Java Broker

>From my point of view for a solution it should have been enough for the clients to connect with max-frame-size accordingly set to 16K without modifying the broker. However, this is not working (the client hangs if sending messages larger than 16K). Meanwhile I got it working: Solution was: 1.)

Re: SSL maximum message size?

Meanwhile I got it working: Solution was: 1.) No need to modify the client c++ api 2.) Don't set max-frame-size in the client (i.e. in connection options) 3.) Modify the java broker to have a max-frame-size of 0x3FFF instead of 0X in

Re: Max Frame Size for Java Broker

Hi, thanks for your feedback. This already helps me a lot. Appearantly I was doing the changes at the wrong positions (ServerDelegate.java instead of ServerConnectionDelegate.java of the 0-10 protocol). I'll redo my experminents. If it's not working I'll generate the corresponding client /

Max Frame Size for Java Broker

Is there any option to set the max frame size of the java broker? Appearantly there was an option qpid.broker_frame_size (see https://qpid.apache.org/releases/qpid-0.32/java-broker/book/Java-Broker-Appendix-System-Properties.html) but it does not seem to be implemented (anymore?). Background of

Re: SSL maximum message size?

True, for the trace I have left the maxFrameSize to its default value(appearantly 64). After this I tested with other frame size options in the connection (max-frame-size:16384 or 8192) I attached a new trace with the 16K setting, the effect is the same (endless loop) Trace16K.txt

Re: SSL maximum message size?

I also tried with max-frame-size 16K or 8K but this does not seem to fix the problem. I also attached a protocol trace as well as a minimum example to reproduce the error. Maybe this is of help to someone. I also tried to understand what exactly is happening within qpid but it is very hard for me

RE: SSL maximum message size?

Yes, fixing the bug would of course make the most sense. Just one more question: In a comment on https://issues.apache.org/jira/browse/QPID-2410 you wrote "In a debugger session I forced the AMQP tune max frame size to 16K and things went swimmingly from there." Maybe I could first try if this

RE: SSL maximum message size?

Hm, this is really getting me into trouble because I need to send encrypted messages of larger sizes than 16k. Is there really no other option, e.g. to link qpid with alternative SSL implementations like OpenSSL or NSS? Could I split up messages into smaller parts and send somehow guarantee that

Re: SSL maximum message size?

Sure, I'll do that asap. Meanwhile, I found a bug report that seems to be very related (its from 2010 but appearantly still unfixed) https://issues.apache.org/jira/browse/QPID-2410 Even the 16K message size seems to be consistent with my tests. I did not fully understand the comments in the bug

Re: SSL maximum message size?

Both c++ client and server are running on Windows 10 64 bit. AMQP version is 0-10. The qpid java message broker is running on Ubuntu, but I suspect that the bug is already on the c++ client / server side. Any hints how to resove this issue? Thx for your help... -- View this message in context:

By the way, I'm using the Java Broker version 6.0.1 together with the qpid c++ messaging api. -- View this message in context: http://qpid.2158936.n2.nabble.com/SSL-maximum-message-size-tp7641114p7641115.html Sent from the Apache Qpid users mailing list archive at Nabble.com.

SSL maximum message size?

Hi, I have noticed that there seems to be a maximum message size if connecting via ssl. I have a request-reply pattern where the client sends a text and the server answers with the identical text. When connecting via "amqp:tcp:servername:5672" I can increase the message length as much as I want.

Re: Several issues with the Java Broker

Ok, I was able to produce a protocol trace with trace+ The situation is as follows: First the client is started. The broker is not active and thus the client is trying to reconnect. Then, after a while, I start the broker. When the broker is almost booted completely, the client receives the

Heartbeating - Java broker

Hi, I'm having a problem to find out how heartbeating exactly works for the java broker (or how to enable it). Via the http management I configured the broker to have a "heartbeat delay" of 5s (this was the only option I could find to somehow enable heartbeating). My test client connects also

Re: Several issues with the Java Broker

Thx for the answer. Im using the newest qpid messaging api (c++), v0.34 together with the newest Java broker (6.0.0). The protocol is AMQP 0-10. I'm afraid that I can't generate a protocol trace with the c++ api, right? But indeed the startup phase of the broker seems to be the problem. If it's

How is it possible to add a user dynamically without having to restart the broker? Probably the REST API could help me here. However, I cannot find any information how such a call would look like. Would be glad if anyone could point me to the right direction. -- View this message in context:
