In jsp editor,codes like out.print("abc"); will be marked as
errors and tipped with "unhandled exception IOException",
I think this is very boring!!

Boring?

The out parameter of the service method is required to be an
instance of javax.servlet.jsp.JspWriter and its print(String) method
is defined to throw an IOException. In a pure .java file this would
cause a compiler warning or error. Is there a reason it shouldn't?

When a jsp file is turned into servlet class,all jsp scriptlets are
put in a try{...}catch(Throwable t){..} block,
So we need not put codes like "out.print(...)" in try catch block!

Will you write jsp like this?
<code>
<%
try{
out.println("abc");
}catch(IOException ioe){
....
}
%>
</code>

Heh, I was referring to your "boring" comment as amusing.

so what's the conclusion to the problem? Though I can ignore, them same
behaviour with my jsp's. Is it possible to turn the marker off?

The error only applies to the JSP editor's built-in error detection
and Content Assist. In no way does it affect how your runtime
translates the .jsp file into a servlet.

You can't turn the marker off (it's not technically a marker), but
reexamination of the 1.2 and 2.0 specifications as well as Tomcat
5.0.x's output is causing us to change the setup we use for JSP Java
Content Assist. The uncatched IOException error specifically is
tracked in https://bugs.eclipse.org/bugs/show_bug.cgi?id=82919,
which will be fixed in the next integration build.
