Re: which 4gl compiler
42r are Four J's extension (www.4js.com). Version specified (3.54) means a pre-genero version called BDS. Unfortunatly, if you do not have *.per and *.4gl, you are doomed: there is no known way to decompile 4js code. Depending on the complexity of the application and specially as it is a web application, I would recommend you investigate Java or PHP. You have an intro on PHP & IDS there: http://tinyurl.com/fx2eu, if you log into the membership area of IIUG.org, you'll have downloadable presentations on Java.
