Dzung Tran updated AXIS2-4823:
------------------------------
Description:
We generate a proxy client using wsdl2Java. We do not have any proxy server
enabled in our system. However, after the system is in use for some time (a few
hours), something sets the system variable http.proxyHost to "" (blank) instead
of null. That is, the call to System.getProperty(HTTP_PROXY_HOST) returns ""
instead of null. We have yet to figure out why this happens.
That causes the following if block in
org.apache.axis2.transport.http.AbstractHTTPSender to evaluate to true and
execute,
// proxy configuration
if (ProxyConfiguration.isProxyEnabled(msgCtx,targetURL)) {
log.debug("ProxyConfiguration");
ProxyConfiguration proxyConfiguration = new ProxyConfiguration();
proxyConfiguration.configure(msgCtx,client,config);
}
Because of this, the program thinks a proxy connection with proxy host = "" is
enabled and it tries to use it. See below
(org.apache.commons.httpclient.HttpConnection)
public void open() throws IOException {
LOG.trace("enter HttpConnection.open()");
final String host = (proxyHostName == null) ? hostName : proxyHostName;
final int port = (proxyHostName == null) ? portNumber : proxyPortNumber;
assertNotOpen();
And because the host is "', we get the error "Address is invalid on local
machine, or port is not valid on remote machine".
This prevents all transactions from being sent to the server, and requires a
restart of our services.
Question:
What is setting the http.proxyHost to blank?
Should blank http.proxyHost be treated the same way as null? (If blanks were
treated like nulls in this case, we wouldn't have this issue.)
