A simple JSF facelets taglib example The simplest taglib I can think of. Using EL expression with a custom tag Make tag attributes dynamic. Mixing custom tag with facelet ui taglibs Discover things you might run into when you get into more details. Which EL context to use? Using the wrong EL context can lead to subtle bugs.

By default SELinux blocks execstack permission. According to Ulrich Drepper : "As the name suggests, this error is raised if a program tries to make its stack (or parts thereof) executable with an mprotect call. This should never, ever be necessary. Stack memory is not executable on most OSes these days and this won't change. Executable stack memory is one of the biggest security problems. An execstack error might in fact be most likely raised by malicious code." You can check if a library/application requires execstack by using the execstack utility:
execstack -q PATHTOPROGRAMYou can try to clean the flag and see if the application still runs:
execstack -c PATHTOPROGRAMTo allow execstack for cc1 :
# grep cc1 /var/log/audit/audit.log | audit2allow ...

These are the steps to diagnose the "javax.jms.Destination found at the specified destination-location" error an MDB in the Oracle application server (oc4j) environment. The data source is correctly configured and connection can be successfully established. Test this from the Oracle AS em console. The destination queue exists and is started. If you are using PL/SQL Developer, you can check this by right clicking on the queue name and make sure that "Enqueue Enabled" and "Dequeue Enabled" are checked. Deployment descriptors are correctly set up. The database user used for the JDBC connection pool has the proper privileges to enqueue and dequeue. Usually this means that the database user is assigned the AQ_USER_ROLE . The ultimate test is to run some PL/SQL code in the oc4j...
