Try quoting each parameter as shown.

Well there's no class name to call in your command. 
I think you mixed up the -classpath option with the class you're trying to call. 
Could it be that it should read (note the space right after $CLASSPATH): 
 
 

<pre><code class="code-1 nolinks" id="code-123352">source /home/xdev/scripts/iicemaker/documents.env

Unix shellscript problem Usage: java [-options] class [args...]

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.
