That seems like a lot of work. Why instantiate java?
<cfscript>
dna = "actg";
newdna = dna;
newdna = replace(newdna,"a","z");
newdna = replace(newdna,"t","a");
newdna = replace(newdna,"z","t");
newdna = replace(newdna,"c","z");
newdna = replace(newdna,"g","c");
newdna = replace(newdna,"z","g");
</cfscript>

<cfset dna = "actg" />

<cfset t.a = "t" />
<cfset t.t = "a" />

<cfoutput>#result.toString()#</cfoutput>
