ServletContext.getResource() doesn't work correctly for files containing hash characters ---------------------------------------------------------------------------------------- Key: WFLY-937 URL: https://issues.jboss.org/browse/WFLY-937 Project: WildFly Issue Type: Bug Security Level: Public(Everyone can see) Components: Web (Undertow) Affects Versions: JBoss AS7 7.2.0.Final, 8.0.0.CR1 Environment: Linux 3.2.0-30-generic Ubuntu SMP x86_64 GNU/Linux Reporter: Christian Kaltepoth Assignee: Stuart Douglas Fix For: 8.0.1.Final Attachments: as7-url-bug.zip {{ServletContext.getResource()}} returns an invalid URL if the file name contains {{#}} characters. Example: {code:java} URL url = servletContext.getResource("/file#1.txt"); {code} The resulting URL object will be spitted at the {{#}} character like this: {code} url.toString(): jndi:/default-host/tomcat-url-bug/file#1.txt url.getPath(): /default-host/tomcat-url-bug/file url.getRef(): 1.txt {code} Calling {{url.openStream()}} will throw a {{FileNotFoundException}}. This is a known Tomcat issue fixed in 7.0.28. References: https://issues.apache.org/bugzilla/show_bug.cgi?id=53257 https://issues.apache.org/bugzilla/show_bug.cgi?id=51584 According to the discussion on the Tomcat issue tracker, there are also problems for other characters which have special meaning in URLs.
