Imagine Lucene being usd in an Applet with some LGPL licenced language handler. If said Applet was something customers would use, you'd be in murky water I imagine. I'm not even sure what the legalities are if all you do is 'distribute' said Applet or Webstart application to a sibling company, or maybe the company who just bought your company. Maybe FUD, maybe legal nightmare. A couple of times reading this thread I felt like suggesting that the ASF have an official Apache LGPL components site, which could depend on Apache ASL components but not vice versa, rather than having lots of unofficial sites, but it quickly becomes obvious that this just isn't a kettle of fish the ASF would want to get into. Maybe the best would be for apache-legal-nightmare.sourceforge.net to exist where we can put all our stuff together. Community driven rather than legally driven. agpl.sourceforge.net.

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.

Hibernate in Apache projects
The Jetspeed team would like to use the Hibernate open source project in our project. http://www.hibernate.org/ I've been reading through the licensing and Im not entirely sure if its compatible with the Apache license. I think I've seen where Turbine now works with Hibernate. Could some one clearly tell us: can we use Hibernate in Apache projects?

This is a good subject w.r.t. Tapestry and HiveMind as well. The previous restriction (ASL 1.1) was that we could not even code against their packages.

RE: Hibernate in Apache projects
As far as I know nothing has changed in regards to linking to LGPL code in ASL code that we host. 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]
Re: Hibernate in Apache projects
I wasn't trying to put you in a bad light -- truly I wasn't. I apologize for coming across that way. I regret that you had a bad experience with OJB and lost development time and effort as a result -- and I want to make OJB better. OJB has definite rough spots, I certainly cannot claim otherwise. It does do a lot of things very well though, and I intend to do what I can to help it get even better (and clean up the rough spots). Release management is something we have done very poorly thus far. I wasn't asking you why were looking at Hibernate (it is a great project), I was offering to try to help make OJB work for you in order to help solve your problem (O/R mapping compatible with the restrictions on what we can put in ASF cvs) as Hibernate, unfortunately, cannot to my knowledge be linked in ASF codebases. I don't have any investment in whether you use OJB, Hibernate, TJDO, Cayenne, Speedo, EJB-CMP, iBatis, Spring-DAO, or Fazoogle Data Objects. -Brian On Apr 20, 2004, at 4:28 PM, David Sean Taylor wrote: On Apr 20, 2004, at 12:59 PM, Brian McCallister wrote: I'm sorry to hear that, I am also sorry to see that I cannot find any posts from you ojb-users or ojb-dev list archives about this =( OJB can be a bear, but the problems you seem to have had (based on the bile in the last email) sound like there was a misunderstanding on how something works.

Release management is something we have done very poorly thus far. We have a lot of code invested in OJB. We'd like to resolve our issues by moving to the latest release candidate (or final release) if possible, if we can pass all unit tests. I for one would like to see Jetspeed-2 continue to support OJB as a persistence back-end, so we can concentrate on other features. Writing a new Hibernate persistence back-end will take up valuable developer time which could be better spent on needed portal features.

I'd like to say that I have used OJB in one project, but I didn't use any of the advanced features. I saw the problems we were having in Jetspeed-2, and steered clear of any complex object-relationship management provided by OJB. This project has now had months of production usage and OJB has performed very well. We don't have one bug logged against OJB. Since you are offering your help, I invite you to join the jetspeed-dev list where we can discuss our issues in more detail. Let me know when you have joined and I will start a thread there.
