Re: [xmlblaster] Problem with Receive

[Marcel Ruff <mr at marcelruff.info>]

Hi Chris,

this is indeed buggy.

I have add a small command line client HelloWorld9 (please use current svn):

java -jar lib/xmlBlaster.jar
java javaclients.HelloWorldPublish -oid hello -numPublish 10 
-destroyDelay 10000000
java HelloWorld9

by hitting enter on HelloWorld9 you enter a receive call.

I have fixed some issues with your receive() already, one
synchronize issue with coming/going topics during a blocking receive()
remains open.
We hope to address this before release 1.3,

regards
Marcel
