(This thread is marginally off-topic, but I can see the value) I can't get any blackdown VM to run on a 2-processor PentiumPro server I have - the vm seg faults on simple Java classes if I'm running the SMP kernel. At my job I have the fortune to identify the required EJB services first, and then pick a corresponding platform that will run it best. Sorry you're not in the same situation.

Please refer to the "$AdditionalHeaders" item for the complete headers. Hi, I would like to ask the list people for experience using an EJB server on linux in a production situation. As linux is our development and deployment platform no 1, we are currently faced with the problem of deciding for an (maybe even more than one) EJB platform for deploying a number of projects. Here are some of our thoughts which I would like people to comment on. Some of the things may be a little off-topic but this is the only place where I can target fellow EJB developers, consultants (and vendors, of course) etc. , so I hope it's OK. One of the main problems of linux in this context is the availability of a good VM. blackdown jdk1.1.7 is stable (at least with green threads) but is significantly slower than other VMs on other platforms even with the tya JIT. the ibm jdk is considered alpha software but I have to admit, that we haven't tried it yet. blackdown jdk1.2 is much faster but far from being a stable server platform as far as our experience is concerned. that leaves us with a stable but slow jdk.1.1.7 for deploying an EJB server. weblogic works fine but is too expensive for some small projects (once you know EJB it seems only natural to use it even in small servlet based web apps where it's hard to convince customers to pay an extra 25000$ because their website resides on a 2-cpu machine, <TO_BEA_SALESPEOPLE> maybe a little more flexibility in your licensing model for an otherwise great product would help here </TO_BEA_SALESPEOPLE>). ejipt (another hot contender) looks very promising but requires jdk1.2 which in our experience is too unstable on linux at the moment. jonas (bullsofts open source ejb server) looks OK but is definitely too slow for applications with a high granularity in their design because it has not been optimized for performance in it's current state of development (especially entity bean handling seems quite inefficient). Are we missing something or does linux really have a problem as far as using it as a platform for EJB deployment? I would like to hear from people who are using linux for EJB in a production situation or are considering to do so. what are your experiences? what combinations of VM, JIT and EJB server (maybe some I have not mentioned like pramati, rickard's free ejb server etc.) are you using and what are the problems associated with that? what trade-offs did you have to make? I hope this is not too far off-topic but I don't know which other list would be more suitable. regards, robert -- (-) Robert Kr
