-----------------------------
Resolution: Not A Problem
This was due to another software that was setting the proxy variables
incorrectly, which affected all threads in the connection.
> Error "Address is invalid on local machine..." occurs when http.proxyHost is
> "" (blank) instead of null.

> Key: AXIS2-4823
> URL: https://issues.apache.org/jira/browse/AXIS2-4823
> Project: Axis2
> Issue Type: Bug
> Components: transports
> Affects Versions: 1.5
> Environment: Windows Sever 2003
> Reporter: Dzung Tran
>
> 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.)
