What version of Tomcat are you using? I'm familiar with 4.x, hope these
answers apply if you are using 5.x. First, Tomcat needs the JDK, not the
JRE, since it uses the Java compiler to compile JSP files into classes.
Second, either 1.4 or 1.5 will work, Tomcat can deal with either. And
lastly, yes it is possible to have 2 versions of Java installed. Tomcat
will uses whichever one the JAVA_HOME environment is pointing to. 

Hope this helps.
