I have this inside my DAO

      public String CSNSurvey() {

        StringBuilder mailstr = new StringBuilder("<html><head>");

        mailstr.append("some text");
        mailstr.append("some text");
        mailstr.append("some text");

        return mailstr.toString();
}

I can make it to work in myservlet but the question is.. How can I include a parameter inside the stringbuilder…

example mailstr.append(“some “+parameter+”text”);

please let me know you need more info to make it clearer.

    Yes I need more information…

    You gave the answer in your question:

    mailstr.append("some "+parameter+" text");

    This code is correct to include a dynamic parameter, even if this syntax is better: 

    mailstr.append("some ").append(parameter).append(" text");

    “parameter” only needs to be a valid java variable. It can be a method parameter, a class field, or a variable declared in the method. Here are two examples:

    public String CSNSurvey(String parameter) {

    StringBuilder mailstr = new StringBuilder("<html><head>");
    mailstr.append("some ").append(parameter).append(" text");

    return mailstr.toString();
}


public String CSNSurvey() {

    String parameter = getDynamicParameterFromAnotherMethod();

    StringBuilder mailstr = new StringBuilder("<html><head>");
    mailstr.append("some ").append(parameter).append(" text");

    return mailstr.toString();
}
