Daniel, THANKS! Works like a charm. Ciao MarkS Daniel Wroblewski wrote: I had a similar problem with OJB in Resin.

It runs fine in Tomcat, and we've had it going in Websphere too. I've got a hunch that it may have something to do with a XML parser/classpath issue, but I could be speaking complete rubbish. So, I don't think you've missed anything obvious. I can't offer anything more concrete than that, I'm afraid, and as my knowledge of Resin is rather less than nothing, I'm not sure I can spend alot of time investigating it right now. Has anyone else using OJB + Resin got any hints for us ?

Re: Problems with OJB in a servlet container
Maybe you use xalan lib different from OJB original version? it can't parse URL to repository.xml file. OJB don't put XMLreader.parse method in try/catch block so you will not be able to see real situation in the log files :(. -- Best regards, Alexandermailto:[EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Problems with OJB in a servlet container
I have seen this first hand - if you have other XML parser versions that are loading in your JVM, it can and will often keep your repository from being properly parsed. In particular, I saw that it often would be unable to resolve the location of the repository.dtd, even when it was clearly in the classpath. Make sure nothing else is in your jre/lib/ext first, then make sure your parses versions match those released with OJB. -Rob -Original Message- From: Alexander Prozor [mailto:[EMAIL PROTECTED] Sent: Friday, June 20, 2003 6:14 AM To: OJB Users List Subject: Re: Problems with OJB in a servlet container Maybe you use xalan lib different from OJB original version? it can't parse URL to repository.xml file.

RE: Problems with OJB in a servlet container
Hi We are using OJB in WebLogic and Tomcat without problems, and we use always the java sdk/vm 1.4.1 for including the default XML parser of the standard 1.4.1 API. Can you verify what version of JVM you use ? Regards, Cristian -Original Message- From: Charles Anthony [mailto:[EMAIL PROTECTED] Sent: Freitag, 20.
