You get "permission denied" error from Apache HTTPD for a page. And you checked file/directory permissions (the whole directory path, not just the file) and everything in httpd.conf . If everything seemed right, then SELinux may be blocking the access. Open /var/log/httpd/error_log , you may see a line like this: [Wed Apr 13 15:50:35 2011] [notice] SELinux poli... These are the steps to fix: If the directory resides in a user home directory: # setsebool -P httpd_read_user_content 1 Create a policy package from the audit log: # grep httpd /var/log/audit/audit.log | audit2allo... Apply the policy package just created # semodule -i mypol.pp Restart apache httpd: # apachectl restart

A task that a Java developer does so frequently is to find out where a certain class can be found - to resolve compilation errors, classpath issues, or version conflicts of the same class introduced by multiple class loaders. A long while back I wrote a simple Perl script to perform the task. Later I was informed that there are Swing based Jar Browser and Jars Browser . Then, there are a couple of shell one-liners: # one liner 1 find -name "*.jar" -print0 | xarg... But all of them share the same problem: if a class is in a jar nested in another jar, it cannot be found. Such is the case for a class inside a jar under the WEB-INF/lib directory of a...

The JBoss Microcontainer provides three StructureDeployer implementations out-of-the-box, with relativeOrder values defined for each: DeclaredStructure: relativeOrder 0 JARStructure: relativeOrder 10000 FileStructure: relativeOrder Integer.MAX_VALUE At deployment time, the StructureDeployer with lower relativeOrder will be consulted first to determine the structure of a deployment. This means that DeclaredStructure is always called first followed by JARStructure and finally FileStructure . DeclaredStructure allows you to specify the structure of a deployment, including any nested deployments, using an XML file named jboss-structure.xml placed in the deployment's META-INF directory. For example, the following is jboss-structure.xml for jbossweb.sar , the JBoss Tomcat service: <?xml version="1.0" encoding="UTF-8"?> <structu...

os.mkdir - Create a directory. Returns None. os.mkdir(path [, mode=0777]) os.makedirs - reate a leaf directory and all intermediate ones. Returns None. os.makedirs(path [, mode=0777]) This works like mkdir, except that any intermediate path segment will be created if it does not exist.
