Or Other possibilities, it should be difficult to say, but I don't recommend it to write it yourself in WIN. Otherwise, I feel that Win often has something to give me empty. No one is using him, I don't know if I feel true. Well, standing platform Linux or freebsd to play eight good luckkoji

[Re: mousetail] Copy to clipboardPosted by: mousetailposted on: 2003-07-09 08:31 Hello, I found that this parameter becomes system Data does not release string st = ""; stringbuffer sb = new stringbuffer (); try {java.net.URL U; string thisline; try {// getting the content U = new java.net.URL (URLLLINK); Try {java.io.inputstream is = u.openStream (); int size = is.available (); while (true) {byte [] ch = new byte [size]; is.read (ch); string string string Strin NEW STRING (CH, "BIG5"); sb.append (STR); if (is.available () <= 0) Break;} is.close ();} catch (exception e) {system.err.println e);}}} catch (java.net.malformedurlexception e) {system.err.println (e);}} catch (exception e) {Out.println ("Exception Caught:" E.getMessage ());} ST = sb.toString (); as long as you will rush to 90% of Tomact, you can't release it for a long time ~~ Is I should implement a completely close? But I'm sb.close () has a mistake without this CLOSE this Method, how can I release it? Thank you 7.Re: Tomcat system resource accounts for 90% ..

[Re: mousetail] Copy to clipboardposted by: mousetailposted on: 2003-07-10 11:17 Thank you for each other, it is still changed to this, but still can't be the first Supreme query is normal, and then respond quickly, it starts to rush to 98% of Code: string st = ""; stringbuffer sb = new stringbuffer (); try {java.net.URL u; string thisline; Try {// Get the content of the web page u = new java.net.URL (urllink); java.io.inputstream is = u.Openstream (); try {int size = is.available (); while (true) { BYTE [] ch = new byte [size]; is.read (ch); string str = new string (ch, "big5"); sb.append (str); // if (is.available () <= 0 IF (is.read (ch) == -1) Break;} is.close ();} catch (exception e) {system.err.println (e);} finally {is.close ();}} Catch (java.net.malformedurlexception e) {system.err.println (e);}} catch (exception e) {Out.println ("Exception Caught:" E.getMessage ());} st = sb.tostring (); SB = NULL; Re-advice, Thank you 10.re: Tomcat system resource accounts for 90% .. [Re: mousetail] Copy to ClipboardPosted by: MouseTailposted on: 2003 -07-10 13:03 Sorry, ask again, it is the reason for the rebound, IF (is.available () <= 0) // if (is.read (ch) == -1) Break; regardless of Which one will not break because I have tried running 10,000 times, I can jump out of the ring. I will ask this question how to solve it. Thank you.

Set 512 is fear IS.available will first catch 0 ... Question I don't know. Question: I can't compile ... so there is no way to solve.> _ <

[Re: mousetail] Copy to clipboardPosted by: mousetailposted on: 2003-07-10 15:51 What is it is really caught 0 but this is Why, then I will change the 512 to a little bit 1024, but if the value of the return in one day is big, is it not enough? Thank you! !

Because the just connection is possible not to pass it to the client end, available () is very likely = 0.available () is the information that is read in the client side. If the value is large, you will read, save a point. Eg Read (CH); append (ch, off, len); good, I have limited capacity (I asked me to bald it), wait for you to ask Home, he can give you the most careful and most standard answer. 16 .Re: Tomcat system resource occupies 90% .. [Re: mousetail] Copy to clipboardPosted by: mousetailposted on: 2003-07-10 17:40 I have to find a file append (char [] str, int offset, INT LEN) OFFSET is the index of the first character to append. It is the first index of the back of the biography string? Isn't it fixed? How do this value take .... Thank you for your enthusiasm! !
17.RE: Tomcat system resource occupies 90% .. [Re: mousetail] Copy to clipboardPosted by: snpshuposted on: 2003-07-11 01: 05biolog has given the right direction .. Next, you will see you .. Previously, I have been successfully repaired, read Mail letters, because the letters are very large, it is easy because of the need to deal with Mine Type many times, but this time the memory is easy to violent ... light is the temporary variable Scary, based on your program demand should be appropriate to adjust variables to handle the efficiency of the modified process, often written with usa ----------------- Tune It's also quite fun ... PS: try catch does not need that multiple layers ...
