http://issues.apache.org/bugzilla/show_bug.cgi?id=40817 Summary: servlet-cgi throws index out of bounds exception on certain cgi Product: Tomcat 5 Version: 5.5.20 Platform: PC OS/Version: Linux Status: NEW Severity: major Priority: P2 Component: Servlets:CGI AssignedTo: tomcat-dev@jakarta.apache.org ReportedBy: [EMAIL PROTECTED] First, servlets-cgi.jar needs to exist and the servlet must be mapped: for example: <servlet-mapping> <servlet-name>cgi</servlet-name> <url-pattern>*.pl</url-pattern> </servlet-mapping> Test perl cgi script: #!/usr/bin/perl print "Content-type: text/plain", "\n\n"; print "Hello world, from Perl\n"; One perl script is placed in www-root ("/test.pl") and the other in any subfolder ("/test/test.pl" or "/cgi-bin/test.pl", etc.) The cgi script in the subfolder will run fine. The cgi script in the www-root will generate an exception: java.lang.StringIndexOutOfBoundsException: String index out of range: -1 java.lang.String.substring(String.java:1768) java.lang.String.substring(String.java:1735) org.apache.catalina.servlets.CGIServlet$CGIEnvironment.findCGI(CGIServlet.java:948) org.apache.catalina.servlets.CGIServlet$CGIEnvironment.setCGIEnvironment(CGIServlet.java:1015) org.apache.catalina.servlets.CGIServlet$CGIEnvironment.<init>(CGIServlet.java:766) org.apache.catalina.servlets.CGIServlet.doGet(CGIServlet.java:584) javax.servlet.http.HttpServlet.service(HttpServlet.java:689) javax.servlet.http.HttpServlet.service(HttpServlet.java:802) The problem is this line (line 948 in CGIServlet.java): cginame = currentLocation.getParent().substring(webAppRootDir.length())+ File.separator + name; The problem is that webAppRootDir is 1 char longer than currentLocation.getParent() because webAppRootDir ends with a File.separator (in this case, a "/"). And removing the extra File.separator from webAppRootDir will result in a different String related exception elsewhere. And here's a fix that works: cginame = (currentLocation.getParent() + File.separator).substring(webAppRootDir.length()) + name; (If necessary, the fix can be made more adaptive by checking to see if it really does have a File.separator at the end and if not...add it...otherwise, let it be, etc.) (on a side note, I have one more bug to fix; the ENV_VAR "SCRIPT_FILENAME" isn't defined as it should be [required for PHP4/5] but I'll submit a different bug/fix for that.) -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
