Subject RE: HttpRecoverableException when using httpClient only in certai n situation
Date Wed, 05 May 2004 16:41:56 GMT
Hi Michael,

Thanks for your reply.  I was mistakenly submit the request twice - which
means that I am using the single instance for multiple thread!

There is another question about the log, I have setProperty for the log as
follows, but I don't see any output for httpClient ...  Why?

System.setProperty("org.apache.commons.logging.Log",
"org.apache.commons.logging.impl.SimpleLog");

System.setProperty("org.apache.commons.logging.simplelog.showdatetime",
"true");

System.setProperty("org.apache.commons.logging.simplelog.log.httpclient.wire
", "debug");

System.setProperty("org.apache.commons.logging.simplelog.log.org.apache.comm
ons.httpclient", "debug");

 
System.setProperty("org.apache.commons.logging.simplelog.log.org.apache.comm
ons.httpclient.Authenticator", "trace");
    System.setProperty("org.apache.commons.logging.simplelog.defaultlog",
"debug");

Hi Jing,

Are you using one instance of HttpClient from multiple threads?  If so, 
makes sure you have a look at 
<http://jakarta.apache.org/commons/httpclient/threading.html>.  If the 
problems continue please post some sample code and a wire log 
<http://jakarta.apache.org/commons/httpclient/logging.html>.

Mike
