replace

I want to replace the first context of

web/style/clients.html

with the java String.replaceFirst method so I can get:

${pageContext.request.contextPath}/style/clients.html

I tried

String test =  "web/style/clients.html".replaceFirst("^.*?/", "hello/");

And this give me:

hello/style/clients.html

but when I do

 String test =  "web/style/clients.html".replaceFirst("^.*?/", "${pageContext.request.contextPath}/");

gives me

java.lang.IllegalArgumentException: Illegal group reference
