How can I get only frame 1 when translating DNA to protein.

I am using the following code to translate to protein but output is a little different from http://translate-protein.com/ (Frame 1) and http://web.expasy.org/translate/ (Frame 1).

SymbolList symL = DNATools.createDNA(input); 

//transcribe to RNA (after biojava 1.4 use this method instead)
symL = DNATools.toRNA(symL);
//translate to protein
symL = RNATools.translate(symL);

out1 = symL.seqString();

I am using BioJava 1.7.1 in Taverna
