[jboss-jira] [JBoss JIRA] Commented: (JBAS-3775) org.jboss.net.protocol.file.FileURLConnection does not handle opening InputStreams to UNC paths properly

[David Kilzer (JIRA)]

David Kilzer commented on JBAS-3775:
------------------------------------

The simple workaround is to open a java.io.FileInputStream to the java.io.File object containing the UNC path and use javax.xml.parsers.DocumentBuilder.parse(InputStream) instead.

> 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 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.
