org.jboss.net.protocol.file.FileURLConnection does not handle opening InputStreams to UNC paths properly -------------------------------------------------------------------------------------------------------- Key: JBAS-3775 URL: http://jira.jboss.com/jira/browse/JBAS-3775 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: Other Affects Versions: JBossAS-4.0.2 Final Environment: Microsoft Windows XP [Version 5.1.2600] java version "1.5.0_07" Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_07-b03) Java HotSpot(TM) Client VM (build 1.5.0_07-b03, mixed mode) Xerces-J 2.6.2 Reporter: David Kilzer Assigned To: Dimitris Andreadis Fix For: JBossAS-5.0.0.CR1 Attempting to parse a document using Xerces-J 2.6.2 by passing in a java.io.File object containing a UNC path fails when run under JBossAS 4.0.2 Final, but works fine when run outside of JBoss. The particular code run under JBoss was started through a Spring-1.2.8-controlled Quartz-1.4.5 job (all deployed within a WAR within an EAR), but the stack trace clearly shows that org.jboss.net.protocol.file.FileURLConnection is the culprit (file path changed to protect the innocent): java.io.FileNotFoundException: \c$\path\to\file.xml at org.jboss.net.protocol.file.FileURLConnection.connect(FileURLConnection.java:80) at org.jboss.net.protocol.file.FileURLConnection.getInputStream(FileURLConnection.java:89) at java.net.URL.openStream(URL.java:1007) at org.apache.xerces.impl.XMLEntityManager.setupCurrentEntity(Unknown Source) at org.apache.xerces.impl.XMLVersionDetector.determineDocVersion(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.DTDConfiguration.parse(Unknown Source) at org.apache.xerces.parsers.XMLParser.parse(Unknown Source) at org.apache.xerces.parsers.DOMParser.parse(Unknown Source) at org.apache.xerces.jaxp.DocumentBuilderImpl.parse(Unknown Source) at javax.xml.parsers.DocumentBuilder.parse(DocumentBuilder.java:172) [...] Here is some sample code that should reproduce the issue. Note the path used to create the java.io.File object. File xmlFile = new File("\\\\127.0.0.1\\c$\\path\\to\\file.xml"): DocumentBuilderFactory factory = new org.apache.xerces.jaxp.DocumentBuilderFactoryImpl(); factory.setNamespaceAware(false); factory.setValidating(false); DocumentBuilder builder = factory.newDocumentBuilder(); Document document = builder.parse(xmlFile); // exception thrown under JBossAS The FileURLConnection class is loaded from jboss-4.0.2/client/jboss-common-client.jar.
