StringBuffer going to append path for every method call

Question

i am setting contextPath dynamically by using StringBuffer in java file. Here for every call the path is appending to StringBuffer Object based on number of calls. How can i run below code properly.

StringBuffer blankDeposit = new StringBuffer();
                blankDeposit.setLength(0);
                String rcp = request.getContextPath();
                String create = "Create";
                blankDeposit.append("<a href="+rcp+"/deposit/showBlankDepositSheet.do>"+create+"</a>"+"a blank Deposit Sheet.");

                ActionHelper.formatInfoMessage(
                    mapping,
                    request,blankDeposit.toString());

Here blankDeposit should have the contextPath(/myapp)with the String. But i am getting a blank space instead of this. How can i do for this.

And the blankDeposit is appending the string by number of times i run. if i call five times then the above variable blankDeposit containing five times the appended string.

Answer 1

This works as expected. Check the contextPath. if that's fine, check any other code block works on blankDeposit.

StringBuffer blankDeposit = new StringBuffer();
blankDeposit.setLength(0);
String rcp = "/myapp";
String create = "Create";
blankDeposit.append("<a href="+rcp+"/deposit/showBlankDepositSheet.do>"+create+"</a>"+"a blank Deposit Sheet.");
System.out.println(blankDeposit.toString());

Output:

<a href=/myapp/deposit/showBlankDepositSheet.do>Create</a>a blank Deposit Sheet.

Answer 2

i got the answer. Here i am passing parameter to the function

ActionHelper.formatInfoMessage(mapping, request,blankDeposit.toString()); 

But instead of that blankDeposit.toString() i am taking as

String rcp = request.getContextPath();

then i am sending this string as an argument to formatInfoMessage method.

ActionHelper.formatInfoMessage(mapping,request,"create.a.blank.deposit.sheet",rcp);

this rcp variable setting to Application.properties file. there it is set as

info.create.deposit.sheet=<a href="{0}/deposit/showBlankSheet.do">Create</a> a blank Sheet.
