Christian H. updated AXIS2-5809:
--------------------------------
Description:
When using HTTP Client 4 with a generated WSDL-Client the HTTP connections are
not returned properly to underlying connection pool. The HTTP connections are
still allocated, when new requests are made. This ends up in waiting for HTTP
connections from pool, but no connections are available anymore.
The connections should be returned to pool as stated in the Apache HTTP Client
4 documentation (2.3.1):
https://hc.apache.org/httpcomponents-client-ga/tutorial/html/connmgmt.html
Here is some example code to reproduce the problem. The BLZServiceStub is a
generated WSDL client (wsdl2java) of the following service:
http://www.thomas-bayer.com/axis2/services/BLZService?wsdl . But the problem is
independent of the used service.
{code:title=TestRunner.java}
package com.thomas_bayer.blz;

import org.apache.http.client.HttpClient;

import org.apache.http.impl.conn.PoolingClientConnectionManager;
import org.apache.http.params.BasicHttpParams;
import org.apache.http.params.CoreConnectionPNames;
import org.apache.http.params.HttpParams;
public class TestRunner {
private static final int timeoutMillis = 5000;
private static final int maxConnections = 2;
private static final String[] BLZs = new String[] {
"12030000", "12070000"
};
public static void main(String[] args) throws RemoteException {
BLZServiceStub blzService = new BLZServiceStub();
blzService._getServiceClient().getServiceContext().getConfigurationContext().setProperty(HTTPConstants.CACHED_HTTP_CLIENT,
buildHttpClient());
for(int i = 0; i <= maxConnections; i++) {
BLZServiceStub.GetBankType getBankType = new BLZServiceStub.GetBankType();
getBankType.setBlz(BLZs[i % BLZs.length]);
BLZServiceStub.GetBank getBank = new BLZServiceStub.GetBank();
getBank.setGetBank(getBankType);
System.out.println("Querying for bank (iteration: " + i + ")");
BLZServiceStub.GetBankResponse response = blzService.getBank(getBank);
System.out.println("Bank queried");
System.out.println("Result: " +
response.getGetBankResponse().getDetails().getBezeichnung());
}
}
protected static HttpClient buildHttpClient() {
final PoolingClientConnectionManager conmgr = new
PoolingClientConnectionManager();
conmgr.setDefaultMaxPerRoute(maxConnections);
conmgr.setMaxTotal(maxConnections);
final HttpParams params = new BasicHttpParams();
params.setLongParameter(CoreConnectionPNames.CONNECTION_TIMEOUT,
timeoutMillis);
params.setLongParameter(CoreConnectionPNames.SO_TIMEOUT, timeoutMillis);
return new DefaultHttpClient(conmgr, params);
}
}
{code}
Running this code will produce the following output:
{noformat}
Querying for bank (iteration: 0)
Bank queried
Result: Deutsche Kreditbank Berlin
Querying for bank (iteration: 1)
Bank queried
Result: Deutsche Bank Ld Brandenburg

The exception is thrown after some timeout waiting for the connection manager
to return a connection. The problem even arised, when i do not set any cached
http client. In that case the problem will arise after 200 requests (default
number of pooled connections within axis2)
