Problems with Message selectors

[oberon]

Hi,

yesterday i tested jms with jboss, everything worked fine, till i tried a message selector

i want to send TextMessages and i set a StringProperty "user" and i set a message selector:
selector = "user != 'someString'";

But when the Client runs on server side the following exception is thrown:

[JBossMQ] javax.jms.JMSException: PARSER ERROR: syntax error
[JBossMQ] at javax.jms.JMSException.(JMSException.java:62)
[JBossMQ] at org.jbossmq.selectors.Selector.(Selector.java:40)
[JBossMQ] at org.jbossmq.Subscription.accepts(Subscription.java:51)
[JBossMQ] at org.jbossmq.server.ClientConsumer.addMessage(ClientConsumer.java:116)
[JBossMQ] at org.jbossmq.server.SharedQueue.run(SharedQueue.java:41)
[JBossMQ] at org.jbossmq.server.JMSServer.run(JMSServer.java:119)
[JBossMQ] at java.lang.Thread.run(Thread.java:481)

Has anybody an idea what i am doing wrong? seems that i have a syntax error in my selector..?!?

Thank you for your help.

It sounds like your selector syntax is incorrect. There is quite a bit of documentation about the selector syntax in the JavaDoc for Message. In short the syntax is a subset of SQL92.

Try <> instead of != for 'not equals'.
