I have to admit, I have only a basic knowledge of Java. And I wouldn't ever touch it. For some reason, when writing in Java, I feel like swimming in tar - possible, but hardly enjoyable. There may be some hidden beauty beyond my knowledge, but I simply don't want to spend time on getting deep into it, so deep that that beauty-of-possibility is revealed. And frankly, I don't believe there is one.

But then "industrial standard" kind of arguments bite, and all of a sudden there is a significant development around in Java. It's totally beyond me why solutions have to be adapted to technologies, not the other way around, but hey, it's real world.

And so, here comes another industrial standard - JMS. But, if you ask me, JMS is no industrial standard. It's a standard way of implementing messaging in Java world. In other words, JMS is a perfect example of a platform-specific technology, created with one thing in mind - to lock the developers to that platform. Many of the J-things are such, don't you think ?

See, JMS is Java Messaging Service, which asserts right from the start that anything non-Java is out. Should its designers have cared about interoperability and ease of integration, they would have standardized an open network protocol. How much easier life would have been if there was simply generic Message Queueing Protocol, say MQP based on TCP, optionally UDP, with very simple and clear semantics for swapping plaintext (i.e. XML) messages. By now we would have had tons of implementations in different languages, of better quality too. Not the case. Not only JMS transport is based on RMI, Java-specific thing by definition, it's also focused on transferring instances of Java classes for messages and/or using messages for object-to-object communications. A perfect lock on Java. Pity.
