HttpException: Already used, but not recycled.

[charu latha]

I am trying to execute a WebService. My method looks as below :

  

public String callService(Hashtable<Object, Object> hash, URL url, Document doc, Envelope msgEnv, String serviceName) throws ServiceException
	{
		StringBuffer buf = new StringBuffer(1000);
		HttpClient client = getClient();
		String timeOutValue = "36000";
	    String connectionTimeOutValue = "60000";
	   	
    	client.setTimeout(Integer.parseInt(timeOutValue));
    	client.setConnectionTimeout(Integer.parseInt(connectionTimeOutValue));
    	client.setHttpConnectionFactoryTimeout(Integer.parseInt(timeOutValue));
	
    	String urlString =url.toString();
     	PostMethod post = new PostMethod(urlString);
     	String response = null;
		InputStream is = null;
		BufferedReader br = null;
	 	
	    try
		{
	    	post.setRequestHeader("Content-type", "text/xml; charset=UTF-8");
	        post.setRequestHeader("SOAPAction", "SOAP_ACTION");
	     
	        StringWriter stringWriter = new StringWriter();
		    SOAPMappingRegistry smr = new SOAPMappingRegistry();
		    msgEnv.marshall(stringWriter, smr);
	        post.setRequestBody(stringWriter.toString());
	        LogUtil.logError(this.logMessage, stringWriter.toString());
			post.setDoAuthentication(true);
			client.executeMethod(post);
is = post.getResponseBodyAsStream();
br = new BufferedReader(new InputStreamReader(is));
	        String line;        
	        while ((line = br.readLine()) != null )
	        {       
	        	buf.append(line);
	        }
	        br.close(); 
	        is.close();
	      
 
		}
	    catch(HttpException e)
	    {
	    	LogUtil.logError(this.logMessage, e);
	    	throw new ServiceException(HTTP_EXCEPTION, e.getMessage());
		}
	    catch (IOException ioe) 
	    {
		
	    	if(ioe instanceof UnknownHostException)
			{
	    		LogUtil.logError(this.logMessage, ioe);
	    		throw new ServiceException(UNKNOWN_HOST_EXCEPTION, ioe.getMessage());
			}
			else if (ioe instanceof ConnectionTimeoutException)
			{
				LogUtil.logError(this.logMessage, ioe);
				throw new ServiceException(CONNECTION_TIMEOUT_EXCEPTION,ioe.getMessage());
			}
			else
			{
				LogUtil.logError(this.logMessage, ioe);
     			throw new ServiceException(HTTP_EXCEPTION,ioe.getMessage());
			}
		}
	    finally
	    {
	    	post.releaseConnection();
	    	if (br != null)
	    	{
	    		try 
	    		{
	    			br.close();
	    		}
	    		catch (IOException ioe)
	    		{
	    			LogUtil.logError(this.logMessage, ioe);
	    		}
	    		
	    	}
	    	if (is != null)
	    	{
	    		try
	    		{
	    			is.close();
	    		}
	    		catch (IOException ioe)
	    		{
	    			LogUtil.logError(this.logMessage, ioe);
	    		}
	    	}
	    }
        response = buf.toString();

When i execute the above method it keeps giving me :

   org.apache.commons.httpclient.HttpException: Already used, but not recycled.
	at org.apache.commons.httpclient.HttpMethodBase.checkExecuteConditions(HttpMethodBase.java:1007)
	at org.apache.commons.httpclient.HttpMethodBase.execute(HttpMethodBase.java:1052)
	at org.apache.commons.httpclient.HttpClient.executeMethod(HttpClient.java:675)
	at org.apache.commons.httpclient.HttpClient.executeMethod(HttpClient.java:529)
 

I've been using this code for a while without any issues. Just today it started giving me this error.

Any suggestions?

Hi. Which statement in your code throws the exception? Were you able to find a solution? If not, please see if this helps. If it does not, then please post enough code in a small program that can be run to duplicate the error.

In HttpMethodBase.java, if you search for "Already used, but not recycled", and then trace the code, that gives an idea of how it works. Of course, you may have already seen all of this ...

client.executeMethod throws the http exception and yes i did look up the answer provided there before i started a thread here for my issue.

Thanks!

I'd be glad to try it if you can post a small sample program that reproduces the error. Or if you find an answer, please do post it.
