Break line in message thrown by custom Exception in Java

Question

I need to break line between my message thrown by custom Exception .

I'm using Struts 2 addActionError() and the error message will be displayed on JSP.

So here is my Java code:

if (result_Of_Scan.equals("ERROR")) {
    throw new AdserverException("We are getting problem with connecting our " 
                    + "Antivirus Server! Please try  again after some time");
}

So I need to show "We are getting problem with connecting our Antivirus Server" on first line and "Please try again after some time" on next line on the browser.

I have tried \\n , <br> and &ltbr&gt but they are not working.

To display the message on the new line in JSP you should use <br> . It didn't display on the new line when you have tried it because <s:actionerror> by default escapes html. You should use escape="false" attribute to change the output to allow rendering html.

<s:if test="hasActionErrors()"> <div class="alert_msg alert"> <s:actionerror escape="false"/> </div> </s:if>
