http://issues.apache.org/bugzilla/show_bug.cgi?id=27520 NullPointerException when using JspC on webapp tree containing unreadable dir Summary: NullPointerException when using JspC on webapp tree containing unreadable dir Product: Tomcat 5 Version: 5.0.16 Platform: PC OS/Version: Linux Status: NEW Severity: Normal Priority: Other Component: Jasper AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] When using JspC, it is possible to get a null pointer exception if the webapp tree you are attempting to compile contains an unreadable directory. Here are the lines that cause the stack trace from JspC.java, CVS version 1.61: 806 if (f.exists() && f.isDirectory()) { 807 String[] files = f.list(); 808 String ext; 809 for (int i = 0; i < files.length; i++) { 810 File f2 = new File(s, files[i]); There is no check before line 809 to see if File.list() returned a null value. Therefore, we get the following stack trace from the jspc Ant task: [jasper2] java.lang.NullPointerException [jasper2] at org.apache.jasper.JspC.scanFiles(JspC.java:809) [jasper2] at org.apache.jasper.JspC.execute(JspC.java:856) [jasper2] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) [jasper2] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) [jasper2] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) [jasper2] at java.lang.reflect.Method.invoke(Method.java:324) [jasper2] at org.apache.tools.ant.TaskAdapter.execute(TaskAdapter.java:157) [jasper2] at org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:306) [jasper2] at org.apache.tools.ant.Task.perform(Task.java:401) [jasper2] at org.apache.tools.ant.taskdefs.Sequential.execute(Sequential.java:102) [jasper2] at org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:306) [jasper2] at org.apache.tools.ant.Task.perform(Task.java:401) [jasper2] at org.apache.tools.ant.taskdefs.Parallel$TaskRunnable.run(Parallel.java:457) [jasper2] at java.lang.Thread.run(Thread.java:536) It would be much nicer if the task simply logged a warning or ignored the unreadable directory. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
