This was the error message:
[ERROR] sun.security.validator.ValidatorExceptio...The certificate was actually signed by Verisign, but somehow failed to pass Java cert validation. To resolve the problem: Download the cert from the server (with RetrieveSSLCert , for example) Import the certificate into the keystore:
$ keytool -import -trustcacerts -alias myserver -f...Define MAVEN_OPTS :
$ export MAVEN_OPTS='-Djavax.net.ssl.trustStore=/h...The quotes must exist for the value of MAVEN_OPTS , and the path must be absolute ( ~/etc/mavenKeyStore.jks does not work).

Suddenly my Windows XP failed to boot with this error message on a blank screen:
missing or corrupt <windows root>\system32\hal.dllI took out the hard drive, put it in a USB enclosure and attached it to another PC. Then I ran CHKDSK and it fixed some file system errors. But I did find that hal.dll was intact, so hal.dll was not missing or corrupt . It turned out that the file that was really missing was C:\boot.ini . It is a hidden file, so you have to use attrib boot.ini to see it. The file is missing if attrib boot.ini returns nothing (run in the root folder C:\). In my case I reconstructed the boot.ini file:
[boot loader] timeout=30 default=multi(0)dis...and changed the attributes back...

This is a script to tail a log file through the web browser. It uses AJAX, apache web server, mod_python, UNIX utilities tail (requires the --lines switch) and wc . The log file may reside on the web server or any other host accessible from the web server through SSH. Although it's written in python, it should be easy to port to other languages such as Perl. Apache httpd.conf :
