If you have installed product components but are having problems and cannot reinstall or uninstall, check the installed component packages using the Solaris pkginfo command, the Linux rpm command, or the HP-UX swlist command. Compare the results with the Java ES packages listed in Chapter 5, List of Installable Packages, in Sun Java Enterprise System 5 Installation Reference for UNIX. Additional troubleshooting information is in Installation Fails Due to Files Left Behind During an Uninstallation.
On Solaris 9 and Solaris 10, you can also use the product registry (prodreg tool) which provides a graphical interfaces that indexes components and their packages, superseding the pkg utilities. To invoke the product registry, type prodreg at the command prompt. For more information, refer to the prodreg(1) man page.
