Question

I have a simple application which renders a jsp file into the browser after getting some data from a servlet.Now I want to add some data in the form of some HTML Tag into the response object coming out of the jsp.

I have made a filter and response wrapper which overrides the getWriter method by returning a custom PrintWriter as:

StringWriter sw = new StringWriter();
public PrintWriter getWriter() {
  return new PrintWriter(sw);
}

Now I am able to retrieve the string from this response object using getString function

public getString(){
   return sw.toString();
}

And I am able to add the content in the string using

str.split("<tag where I have to add>");

But now I want to render this string into my Browser.

Will I have to create some other Wrapper object? Or please suggest any other way to achieve this.Any help will be appreciated.

Thanks.

Answer 1

You are overruling the existing writer of the response object. You should keep a reference to that one and in the end write the final/modified content to that writer.
