Steps to configure SSL for Apache HTTPD server on Windows: In Apache2.2/conf/httpd.conf , load mod_ssl and include httpd-ssl.conf : LoadModule ssl_module modules/mod_ssl.so ... In Apache2.2/conf/extra/httpd-ssl.conf , make sure the paths for the cert files point to the cert and key you want to use: # Server Certificate: # Point SSLCertificat... Start up Apache. If it fails, use the command line to see what the error is. There won't be any log in error.log if there are errors in the conf files: C:\Program Files (x86)\Apache Software Foundation\... I corrected the previous error by using the alternative line for SSLSessionCache : # Inter-Process Session Cache: # Configure ...

Tomcat 7.0 failed with a SEVERE error without printing a stack trace: Dec 30, 2011 1:21:09 PM org.apache.catalina.core.S... Now it's hard to figure out what's wrong without knowing where things went wrong. Why is Tomcat not logging anything? Tomcat logging is configured by class loader. Logging behaves differently depending on which class loader loaded the logger. You'll need to look at both $CATALINA_BASE/conf/logging.properties and WEB-INF/classes/logging.properties to figure out why the stack trace is not logged. In my case, the web app specific WEB-INF/classes/logging.properties overshadowed the system $CATALINA_BASE/conf/logging.properties and suppressed the stack trace.

My problem is simple: in my XML data, a timestamp is provided as a long integer (number of milliseconds since the "the epoch"). When I do XSLT, I want to display it as a readable string, such as "Mon Nov 01 18:08:48 CDT 2010". After hours of struggle, I found: It's not so easy to get the job done with JDK 1.6 There are tons of garbage on the web in this space (suggestions, code snippets that simply don't work) Simple Xalan extension functions was the only resource that's somewhat informative. Even there some of the examples don't work. Below is a list of what worked and what didn't. This works: <xsl:stylesheet version="1.0" xmlns:xsl="h... This does not (providing long value to Date constructor): <xsl:stylesheet version="1.0" xmlns:xsl="h......

By default, alfresco.log is located in the current working directory (where you started Tomcat from). But you can override the default location with a custom lo4g.properties file: Create file $TOMCAT_HOME/shared/classes/alfresco/extension/custom-log4j.properties with contents: log4j.rootLogger=error, File log4j.appender... The Alfresco log will be relocated to /home/alfresco/logs (but somehow s small portion remains in the CWD). This works only when the shared.loader property in conf/catalina.properties includes ${catalina.home}/shared/classes .

The stack trace is like this: java.lang.IllegalArgumentException: Component prop... You get this error because you are using the class attribute with a JSF UI component, for which the class attribute cannot be altered. Of course you meant CSS class, not Java class! You can use the styleClass attribute instead of the class attribute. The styleClass attribute becomes the class attribute when the component is rendered. If you can add a tag handler to the UI component, you can alias class to styleClass , which will allow you to use the class attribute on the UI component: import javax.faces.view.facelets.*; pub...

This error happened when I loaded a JSF page, using Apache MyFaces. From the stack trace it looked like the XML parser failed, but in reality the runtime was not able to load the class specified in the handler-class element - a typo in the class name! That's the price you pay for wiring together components with XML! This was the stack trace: Caused by: org.xml.sax.SAXException: Error Handlin...

I built a very basic JSF application and deployed to Tomcat 7.0.22, but it failed with this error: Caused by: java.lang.ClassFormatError: Absent Code... That looks weird and I wasn't able to find a sensible explanation! So I copied the jsf-api-2.1.jar , which was downloaded from the java.net Maven repository by Maven, into a temp folder. And tested it with this simple program: public class ClassFormatErrorTest { public ... I also copied servlet-api.jar from Tomcat's lib folder to the temp folder. Sure enough it failed with the same error: C:\tmp>java -cp .;jsf-api-2.1.jar;servlet-api.jar ... But when I replaced the javax.faces.webapp.FacesServlet class with one I compiled from source, the error disappears! Conclusions: The jar file jsf-api-2.1.jar from java.net Maven repository is good for compilation only (cannot be used...

From Fedora Project wiki : A security context , or security label , is the mechanism used by SELinux to classify resources, such as processes and files, on a SELinux-enabled system. This context allows SELinux to enforce rules for how and by whom a given resource should be accessed. A security context is typically shown as a string consisting of three or four words. Each word specifies a different component of the security context, namely, the user , role , type , and level of that file or process . Each word is separated by a colon. Use the -Z switch to display security context info. Display security context for Apache files: $ ls -Z /var/www/ drwxr-xr-x. root root system_... Display security for files under...
