I’m doing some research for an article I’m writing for Macromedia Devnet (hopefully to be published in May or June). I won’t go into the details of the article, but part of it deals (tangentially<\/a>) with CFMX and Java integration. Specifically, I’m using CFMX to call a relatively simple Java API that consists of a couple methods, ie:<\/p>\n

doSomething(javax.servlet.http.HttpServletRequest req, javax.servlet.http.HttpServletResponse res, long someObject) <\/p>\n

Looks pretty imposing doesn’t it? It’s actually pretty easy to call using CFMX. <\/p>\n

<cfscript>
\n myObject = CreateObject(“java”, “com.thirdpartyApp.OtherClass”);
\n \/\/ retrieve the long value from the third party class
\n t = CreateObject(“java”, “com.thirdpartyApp.Class”);
\n longValue = t.SOME_CONSTANT;<\/p>\n

\/\/ get a javax.servlet.http.HttpServletRequest object from CFMX
\n req = getPageContext().getRequest(); <\/p>\n

\/\/ get a javax.servlet.http.HttpServletResponse object from CFMX
\n res = getPageContext().getResponse(); <\/p>\n

myObject.doSomething(req, res, longValue);
\n<\/cfscript><\/p>\n

One interesting to note is that if you do getClass() on the req and res objects like this:<\/p>\n

<cfoutput>#req.getClass()#<\/cfoutput>
\n<cfoutput>#res.getClass()#<\/cfoutput><\/p>\n

above you get the following class names:<\/p>\n

req = jrun.servlet.ForwardRequest
\nres = coldfusion.jsp.JspWriterIncludeResponse<\/p>\n

and although they don’t look like javax.servlet.http.HttpServletResponse and javax.servlet.http.HttpServletRequest objects, they actually extend the javax.servlet.ServletRequestWrapper<\/a> and javax.servlet.ServletResponseWrapper<\/a> classes, which are wrappers (as their names imply) for the javax.servlet.ServletRequest<\/a> and javax.servlet.ServetResponse<\/a> interfaces. <\/p>\n

Anyway, interesting journey.. great help from Sean Corfield<\/a> for his post<\/a> about the getClass() method you can use to find out the type of an object and to Charlie Arehart<\/a> for his comprehensive Java\/CFMX archive<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
