Roy once pointed out why he things the LGPL is more or less identical to the GPL when it comes to Java[1]. If he's correct, the only option really would be a layer in between as Noel says, something that completely abstracts away the library (like JDBC) or maybe a layer purely based on JMX. While ASL and LGPL may or may not be compatible (or could be made compatible with layers in between), this is not really the main issue for Apache releases IIUC. If your release requires a LGPL library and doesn't work without it, it means that all your users have to accept the LGPL in addition to the Apache Software license. This is true for any other other license as well, that's why mixing licenses should be avoided anyway. Let's assume for a moment that ASL and LGPL would be compatible. We could release a combined work, no problem. A pure end-user would pick up the release and has to accept both licenses, probably no problem either. But if a company wants to build a product on top of our release - something the ASF encourages strongly - they probably will have a problem with accepting the LGPL.

As I understand it, we do not want to link to LGPL code directly, but can use it under another interface, e.g., we cannot import an LGPL package, but if we have an LGPL service provider for JDBC, JNDI, etc., that is OK. > if there is anything that Hibernate does that OJB doesn't, let > us know and we'll fix that problem =) The only major feature > Hibernate has that OJB does not is a marketing budget, to my knowledge. Oh that is rediculous, if true! I hear about Hiberate all the time, but I never hear about OJB, and I had no idea it was in the same domain. We really need to help promote our own dogfood, at least to each other. And, we need to improve inter-project collaboration so that when there are issues, people find out about them so that they can fix them. --- Noel - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
