Handling java.io.IOException ?

Question

Hi !
Keep getting the following error :
"Unreported Exception java.io.IOException; must be caught or declared to be thrown"
Using a throw as in "public void doGet(HttpServletResuest svreq, HttpServletResponse svresp) throws IOException" works well but
I want to catch it along with SQLException and Exception :
... (fragment code follows) ...
public class LstEmpHandle extends HttpServlet
public void doGet(HttpServletRequest svreq, HttpServletResponse svresp)
{ ... some declarations ...
try { ... more code...
} catch (IOException exc ) {"IOException: "+ exc.getErrorCode() + " : " + exc.getMessage();}
catch (SQLException exc) {..;.;}
catch (Exception exc){...}
finally (...)
That is the only complain the compiler has got !

Hi !
I do have "System.out.println" which I did not include in my fragment code.
If I do this, there are no compile-time errors
public void doGet(HttpServletRequest svreq, HttpServletResponse svresp) throws IOException
{  ResultSet rs = null;
Connection myconn = null;
Statement mystmt = null;
int rowCnt = 0;
PrintWriter out =svresp.getWriter() ;
svresp.ContentType("text/html");
try { ... code code code ...
} catch ( SQLException exc)
{ System.out.println("error code : " + exc.getErrorCode() + " :: " +                  exc.getErrorMessage());}
catch (Exception exc)
{System.out.println("Exception :" + exc.getErrorMessage());}
finally { try ... etc ...}
However, if I want to trap the IOException along with other exceptions I get the aforementioned error:
public void doGet(HttpServletRequest svreq, HttpServletResponse svresp)
{ ResultSet rs = null;
Connection myconn = null;
Statement mystmt = null;
int rowCnt = 0;
PrintWriter out =svresp.getWriter() ; //javac throws compile time error here
svresp.ContentType("text/html");
try { ... code code code ...
} catch (IOException exc)
{ System.out.println(IOException occurred :" + exc.getMessage());}
catch ( SQLException exc) // here is where error is at compile time
{ System.out.println("error code : " + exc.getErrorCode() + " :: " +                  exc.getErrorMessage());}
catch (Exception exc)
{System.out.println("Exception :" + exc.getErrorMessage());}
finally { try ... etc ...}
