Hi,
I am running a junit test case, where the test methods would submit http
client requests to the target application server (WebSphere 8) which hosts
the serving application.
While running the test case, I randomly run into the following error, where
in first run, say testA() would fail, and in a successive test run testA()
would pass but some other test method, say testB() would fail with the same
error message as listed below.
I am not sure what is happening as it not a constant error occurring for
the same method.
What's more confusing is, the Servlet listening to the HTTP requests is not
at all called when this error occurred. And also, I do not see any error
messages at the server side.
Following is the code which is used to construct the httpclient.
DefaultHttpClient httpClient = new DefaultHttpClient(_connectionManager,
null);
HttpParams params = new BasicHttpParams();
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, "UTF-8");
// HttpProtocolParams.setUseExpectContinue(params, true);
HttpProtocolParams.setUseExpectContinue(params, false);
HttpConnectionParams.setTcpNoDelay(params, true);
HttpConnectionParams.setSocketBufferSize(params, 128000);
HttpConnectionParams.setStaleCheckingEnabled(params, true);
// determine the release version from packaged version info
final VersionInfo vi = VersionInfo.loadVersionInfo
("org.apache.http.client", JavaHttpServiceCreator.class.getClassLoader());
final String release = (vi != null) ? vi.getRelease() :
VersionInfo.UNAVAILABLE;
HttpProtocolParams.setUserAgent(params, "Apache-HttpClient/IIS " + release
+ " (java 1.5)");
AuthParams.setCredentialCharset(params, "UTF-8");
httpClient.setParams(params);
java.rmi.RemoteException: null; nested exception is:
