On Mon, 23 Feb 2004, marc salvetti wrote: i use the latest ojb version (rc5) See the answer from armin, this message seems not to be related with the current pb, it is apparently for sequence generation From what I gather, it seems as if there was a problem with the Resin build-in xml parser and xslt processor (at least in versions 2.1.6/7, but may still be present). These did not resolve entities correctly. Even if that is not your actual problem, you might want to try the solution: replace the xml parser (and xslt processor) that resin uses. Somewhere in the resin config (webapp config ?), you specify these system-properties: system-property javax.xml.transform.TransformerFactory= org.apache.xalan.processor.TransformerFactoryImpl/ system-property javax.xml.parsers.DocumentBuilderFactory= org.apache.xerces.jaxp.DocumentBuilderFactoryImpl/ system-property javax.xml.parsers.SAXParserFactory= org.apache.xerces.jaxp.SAXParserFactoryImpl/ (these are for xerces/xalan). You also have to put the corresponding libraries into the lib folder of your webapp. Tom - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

From what you posted it seems more like a problem with the XML parser, as the isolation-level (which you probably didn't specify at first) wasn't read. If you don't specify an attribute value, the XML parser is supposed to fetch the default value from the DTD (if it exists), and if there is no default value (because e.g. it's CDATA) then a null is returned.

Re: FW: deploy OJB with web application
Armin. Thanks for your reply. We found the problem. It is because resin has it's own XML parser which is not exactly the same as apache's. And when resin starts, it loads its own library before loading from WEB-INF/lib. The problem can be solved by explicitly putting xerces.jar in the classpath.

I don't think there is any document saying that we need to change repository_internal.xml. I am wondering whether anybody has ever had the same problem and what's the real cause and the soultion for it. Thanks in advance.

Re: FW: deploy OJB with web application
Armin, Thanks for your reply. Here is a portion of my repository.xml. I am not sure whether the missing attribute for proxy-prefetching-limit causes the problem? descriptor-repository version=1.0 isolation-level=read-uncommitted !-- include all used database connections -- database; !-- include ojb internal mappings here -- internal; Thanks, Zhe -Original Message- From: Armin Waibel [mailto:[EMAIL PROTECTED] Sent: Thursday, January 22, 2004 3:28 AM To: OJB Users List Subject: Re: deploy OJB with web application Hi, ZZZ Liu wrote: I am using OJB rc5. Everything is fine when I use it for stand alone program. But when I try to use it in a web application (applciation server is resin 2.1.10), I got following error. From the log, we can see that there is a NullPointerException at org.apache.ojb.broker.metadata.RepositoryXmlHandler.getIsoLevel(Unknown Source) and from the debug message we can see that isolation-level: null. hmm, think something wrong with your file:/D:/gsnx/builds/hourly/dist/gsnx/conf/repository.xml file. Should be something like that: descriptor-repository version=1.0 isolation-level=read-uncommitted proxy-prefetching-limit=50 !-- include all used database connections -- database; !-- include ojb internal mappings here -- internal; !-- include user defined mappings here -- user; /descriptor-repository regards, Armin If I manually add isolation-level attribute to each class descriptor element in repository_internal.xml and all included repository_user.xml's, then it works. I don't think there is any document saying that we need to change repository_internal.xml. I am wondering whether anybody has ever had the same problem and what's the real cause and the soultion for it. Thanks in advance.
