I don't know if this will help but later versions of xerces implement JAXP so I deleted the parser.jar that comes with Orion and replaced the xerces jar with the one that comes with the latest xalan and things are working. Let us know if that helps. -----Original Message----- From: Arno Grbac [mailto:[EMAIL PROTECTED]] Sent: Wednesday, March 21, 2001 12:13 PM To: Orion-Interest Subject: Is there a solution to JAXP 1.1? ORION WON'T START!!! I searched the list, and people have experienced this problem (like myself), but no word from Orion. Ideas? If you try to get Orion working with this latest release from Sun, Orion won't start: G:\orion>java -jar orion.jar java.lang.NoSuchMethodError at org.apache.crimson.tree.AttributeSet.<init>(AttributeSet.java:139) at org.apache.crimson.tree.XmlDocumentBuilder.startElement(XmlDocumentBuild er.j ava:463) at org.apache.crimson.parser.Parser2.maybeElement(Parser2.java:1449) at org.apache.crimson.parser.Parser2.parseInternal(Parser2.java:499) at org.apache.crimson.parser.Parser2.parse(Parser2.java:304) at org.apache.crimson.parser.XMLReaderImpl.parse(XMLReaderImpl.java:433) at org.apache.crimson.jaxp.DocumentBuilderImpl.parse(DocumentBuilderImpl.ja va:1 79) at com.evermind.xml.e.getJavaxDocument(JAX) at com.evermind.xml.XMLUtils.getDocument(JAX) at com.evermind.xml.XMLConfig.ay(JAX) at com.evermind.xml.XMLConfig.ay(JAX) at com.evermind.server.g6.run(JAX) at java.lang.Thread.run(Unknown Source) at com.evermind.util.f.run(JAX) I don't think it's a hard thing to fix and it is a critical bug if you need the latest stuff. Did anybody figure this out? Regards, -arnox
