I found j2sdk1_5_0* and J2RE1_5_0* many places in the
installation document from the following doc URL:

http://webwork.sfbay/j2se/1.5.0/install-solaris.html

Example: chmod +x j2sdk-1_5_0_<version>-solaris-sparc.sh

it should be chmod +x jdk-1_5_0_<version>-solaris-sparc.sh


Steps to get the installation doc:

1. http://webwork.sfbay/j2se/1.5.0/download.jsp
    click VIEW from SDK Installation Instructions
2. http://webwork.sfbay/j2se/1.5.0/install.html
    click "J2SDK for Solaris"
3. http://webwork.sfbay/j2se/1.5.0/install-solaris.html
