Licensing

Sun Web Stack is a set of many components from third party open source projects. Each of these components has its own license, as chosen by the third party which owns the component. The following table lists various licenses used in Sun Web Stack.

The Sun-owned source code which includes Installer and Registration tool is under CDDL (http://www.sun.com/cddl/) .

Known Issues

This section contains information on known bugs and problems in this release and instructions on fixing, avoiding or working around them.

• Sun Web Stack install may fail due to the unavailable dependent packages which are not part of the default Operating System installation. See Additional Package Dependencies.
• Apache Tomcat Server on RHEL depends upon Sun-supplied JDK rpm. This is satisfied by installing the Sun JDK RPM package. Non-rpm distributions of the JDK will not allow the Apache Tomcat Server to install without using the rpm command to bypass dependencies. Download and install the latest Sun JDK RPM package available at http://java.sun.com/javase/downloads/index.jsp. Verify that JAVA_HOME is pointing to the newly installed SDK.
• mod_perl on Solaris 10 and OpenSolaris platforms use system Perl which is not thread-safe. Therefore mod_perl cannot be used with the threaded MPM (worker) on Solaris 10 and OpenSolaris platforms. If mod_perl is loaded, it will cause Apache HTTP Server to fail initialization and the following message will appear on the Apache HTTP Server error log:

  [error] cannot use threaded MPM without ithreads enabled Perl
  

• On RHEL x64 based platforms, Java-based installers (such as GlassFish) bundled with Sun Web Stack fails with an error. This is because the default installer uses the JAVA_HOME environment variable which points to 64-bit JRE. The recommended fix is to install a 32-bit JRE (Sun JRE is recommended) and set JAVA_HOME to a 32-bit JRE directory.

• Apache Tomcat Server, by default runs in the development mode. To turn off the development mode, edit <tomcat>/config/web.xml to include development parameter in the JSP servlet.
