Re: [Htmlparser-user] why the propram stop sometimes?

[JeffJie <Je...@bo...>]

thank you.I have add the code to my main program.it seems work.but in fact the code doesn't work for the right place.

another block of my code:
Page page = new Page(manager.openConnection(url));
            page.setEncoding(Global.PAGE_ENCODING);
            ps = new Parser(new Lexer(page));
after adding the timeout,when connection timeout occur.a ParserException was throwed :
Exception getting input stream from http://localhost:8081/test/count

then look back the code last time I paste here:

fb.setParser(ps);

the program still stop here sometimes.seems the time out doesn't work.
could you please help me find out the answer.thank you!
