Re: Pure Master Slave not working

Hi Joe, I am getting the same 'out of sync' exception while using pure master/slave (5.0.0). Were you able to fix the problem in your case? The problem begins at relatively heavy load (> 50 clients). The performance keeeps degrading & finally the system hangs. Any ideas would be appreciated. Tha

Thank you for the response. I got over the problem when I set false for JMX connection and providing connector URL. Now my messaging is working fine. Any idea what can be the impact of this? -Manoj ttmdev wrote: > > You typically get a BindException when you try and bind to a port that has

I followed the directions and got the libactivemq-cppd.lib file to build. However, I get a lot of linker errors when I try to compile the example. Does anyone have a working project or solution file that I can use to get the example to compile? I copied the settings straight from the VS2005 pro

Re: ActiveMQ 5.0 & JAAS: SecurityException: User name or password is invalid on Startup

Are the files users.properties, login.config, and groups.properties in $ACTIVEMQ_HOME/conf? I noticed that you have both the jaas and simple authentication plugins enabled in your broker's xml cfg file. Try commenting out the simple plugin. Can you clients connect to the broker? Joe navnetk

Re: ActiveMQ 5.0 & JAAS: SecurityException: User name or password is invalid on Startup

Couple of things to keep in mind. a. Any broker wishing to connect to this broker (i.e., the one you've enabled security for) will need to provide the proper credentials via the networkConnector element's userName and password attributes. b. Any networkConnector elements given to this broker m

ActiveMQ 5.0 & JAAS: SecurityException: User name or password is invalid on Startup

Hi, I configured JAAS & ActiveMQ 5.0. On ActiveMQ startup, I get the User name or password is invalid exception. (stacktrace mentioned in the end of this post). I've been through all the related posts & have tried the suggestions, even then this doesn't work ! Attached are the configuration f

setting a MessageListener on a consumer?

I'm using the method below to create a Topic and Consumer and register my MessageListener. I'm worried that with a retroactive consumer I'm missing messages between the .createConsumer() method and when the MessageListener is actually registered with the MessageConsumer. Shouldn't there be some w

Found it :) The message was sent as a JMS BytesMessage (instead of a TextMessage) and the object property names have to be in lowercase. I am more than happy now =) Kind Regards Michael Justin mjustin wrote: > > The Delphi-generated version does not show up as SamplePojo object in the > admin

Re: jms-json transformation: missing library

Hi Dejan, meanwhile I found out how a JSON-encoded java object encodes the class name. Now I can see that I can generate JSON-encoded objects with Java and Delphi, the differences are very small. Only the order of the fields changes: Generated by the Java producer: {"SamplePojo":{"name":"myname

Hello Dejan, many thanks - it works like a charm now. Now I am stuck just at the next corner and could have know before: I wrote a SamplePojo class and send it from a Java producer tool, and it successfully shows up in the web admin console. It appears in the typical Java notation in the 'Mess

Hi, I am facing the same issue with 5.0.0. Has something been done about it? The Master/Slave topology seeems to work fine for a small number of clients (around 20-30) but fails after that. This might turn out to be a showstopper for us. Thanks, Ramit TBuckel wrote: > > Raised a JIRE ticket. At

Re: running ActiveMQ in a load balanced tomcat

You typically get a BindException when you try and bind to a port that has already been taken by another process or thread. So it looks like you have more than one embedded broker, in your load balanced cluster, trying to bind to the same port on the same machine. Joe Goto www.ttmsolutions.com f

Re: jms-json transformation: missing library

Hi Michael, you are right, XStream is an optional dependency, so you have to put it manually into the lib/ folder. Additionally, you have to include jettison (http://jettison.codehaus.org) into broker's classpath if you plan to use JSON. I've just updated docs with this info (http://cwiki.apache.o

Hi Ramit, you can take a look at how this functionality is implemented in PHP client (http://stomp.codehaus.org/PHP+Connectivity). Basically, you can detect that broker is down when you try to read/write from a socket and implement reconnection logic in those cases. BTW. error frames are sent to t
