Martin, please have a look at this example: http://cvs.apache.org/viewcvs.cgi/jakarta-commons/httpclient/src/examples/ChunkEncodedPost.java?rev=1.4.2.1only_with_tag=HTTPCLIENT_2_0_BRANCHview=auto (link may be wrapped) Kind regards Ortwin Glück martin hilpert wrote: Hello, i using the HttpClient in a Java Applet but if i transfer a file larger then 32MB i get a OutOfMemory. does some others has the same bug? greetz from Germany Martin -- _ NOSE applied intelligence ag ortwin glück [www] http://www.nose.ch software engineer [email] [EMAIL PROTECTED] hardturmstrasse 171 [pgp id] 0x81CF3416 8005 zürich [office] +41-1-277 57 35 switzerland [fax] +41-1-277 57 12 - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Hallo Ortwin so schnell findet man sich wieder, du hast in der einen Java NG geantwortet http://cvs.apache.org/viewcvs.cgi/jakarta-commons/httpclient/src/examples/Ch unkEncodedPost.java?rev=1.4.2.1only_with_tag=HTTPCLIENT_2_0_BRANCHview=aut o gruß martin - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: OutOfMemory if using PUT
Martin, The problem is most likely caused by the PUT method buffering the request body in order to determine its length You can avoid this problem by (1) using chunk-encoding http://cvs.apache.org/viewcvs.cgi/jakarta-commons/httpclient/src/examples/ChunkEncodedPost.java?rev=1.4.2.1only_with_tag=HTTPCLIENT_2_0_BRANCHview=markup (2) explicitly specifying the content length http://cvs.apache.org/viewcvs.cgi/jakarta-commons/httpclient/src/examples/UnbufferedPost.java?rev=1.2.2.1only_with_tag=HTTPCLIENT_2_0_BRANCHview=markup Oleg -Original Message- From: martin hilpert [mailto:[EMAIL PROTECTED] Sent: Wednesday, March 17, 2004 11:09 To: [EMAIL PROTECTED] Subject: OutOfMemory if using PUT Hello, i using the HttpClient in a Java Applet but if i transfer a file larger then 32MB i get a OutOfMemory. does some others has the same bug? greetz from Germany Martin *** The information in this email is confidential and may be legally privileged.

Re: OutOfMemory if using PUT
Hello Oleg, The problem is most likely caused by the PUT method buffering the request body in order to determine its length that means there is no work around WITH PUT ? You can avoid this problem by (1) using chunk-encoding http://cvs.apache.org/viewcvs.cgi/jakarta-commons/httpclient/src/examples/Ch unkEncodedPost.java?rev=1.4.2.1only_with_tag=HTTPCLIENT_2_0_BRANCHview=mar kup (2) explicitly specifying the content length http://cvs.apache.org/viewcvs.cgi/jakarta-commons/httpclient/src/examples/Un bufferedPost.java?rev=1.2.2.1only_with_tag=HTTPCLIENT_2_0_BRANCHview=marku p that are both POST requests? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

The same applies to PUT methods as well as PUT basically works the same as POST. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: OutOfMemory if using PUT
ok first thank it work now with files larger 32mb, but there is still a another problem. if the user transfer a large file like 32MB over a normal DSL connection (128kbit up / 796 kbit down) how could i find out how many bytes are send? is there anyway? martin - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: OutOfMemory if using PUT
Hi Ortwin, Not from within HttpClient directly. You can however simply wrap your stream and count the bytes read through the respective methods. how can i wrap it? any sampel code? thx martin - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

It is intended to be a base class for such a thing linke you need. If you are using Swing you can just use javax.swing.ProgressMonitorInputStream.

Re: OutOfMemory if using PUT
Hi, yes i heard about that class. no i dont use any swing control, i use awt. Errm... Ever heard of the java.io.FilterInputStream class? It is intended to be a base class for such a thing linke you need. If you are using Swing you can just use javax.swing.ProgressMonitorInputStream. i dont understand how i can monitor the stream. HttpClient client = new HttpClient(); PutMethod put = new PutMethod(zielurl); FileInputStream fin =new FileInputStream(C:\test.jpg); put.setRequestBody(fin); put.setRequestContentLength(PutMethod.CONTENT_LENGTH_CHUNKED); client.executeMethod(put); System.out.print(put.getResponseBodyAsString()); put.releaseConnection(); - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
