Catching Web Service Error in JSP

[Former Member]

I have a JSP page that consumes a webservice. The JSP page mostly consist of HTML tags and some java codes (for consuming web service). If my web service fails for some reason, I want the page to still show an page that still works (without the error report). That page will not contain my code for consuming web service. Can I do this using just try catch block?

e.g.

<% try{
//connection to web service
%>
<h1>
<%
String var1 = getMethod("1","1");
out.write(var1); //will output Hello
%>
</h1>

<%
}catch (Exception e){
<h1>Hello</h1> <!--my original html page-->
}
%>

This will not work right? Cause you need to have a pure java code inside try catch block. Is there any other way to catch the web service error and still output my original page? Thanks

Looks like I can somehow catch some errors using try catch. I just need to print all my HTML tags in the try catch. My problem know is I can only catch errors in web service lookup. Still can't catch 500 internal server error (Error compiling) and 500 internal server error (error parsing). Is there a way to catch these errors and print a custom error message?
