Subject: Axis2: Unable to make the http connection.
From: [email protected]
To: [email protected]
Hi,
I have an environment where we have multiple 3pp nodes using different
protocol (SOAP and telnet). For each 3pp node we have different packages
developed in java for communication.
There are four services which are using SOAP protocol and 3 are using axis/jax
rpc and one is developed using axis2 framework.
All application is working fine till the time 2 other application are executed
(using axis/jax rpc and xml/rpc) executes the commands.
One single command from any application makes the application (developed in
axis2 framework) unreable .
I have check the connectivity between and the environment, it remains reachable
but application is unable to get the connection. However the restarting the
whole environment makes that (axis2 developed) application reachable till the
time these 2 conflicting application are not executed.
once they executes any command it this axis2 developed application causes the
same pb.
Below is the exception I am getting
java.lang.NumberFormatException: For input string: "" at
java.lang.NumberFormatException.forInputString(NumberFormatException.java:48)

MG>stop right here because you have a misconfiguration
public void configure(MessageContext messageContext,
HttpClient httpClient,
HostConfiguration config) throws AxisFault {
// <parameter name="Proxy">
// <Configuration>
// <ProxyHost>example.org</ProxyHost>
// <ProxyPort>5678</ProxyPort>
// <ProxyUser>EXAMPLE\saminda</ProxyUser>
// <ProxyPassword>ppp</ProxyPassword>
// </Configuration>
// </parameter>
Credentials proxyCred = null;
//Getting configuration values from Axis2.xml
Parameter param =
messageContext.getConfigurationContext().getAxisConfiguration()
.getParameter(ATTR_PROXY);
MG>are you SURE you have a valid numeric value in <ProxyPort>5678</ProxyPort>
in axis2.xml or did you leave it as ""?
MG>3 solutions straight from axis documentation:
Prior shown configuration has been deprecated after Axis2 1.2 release and we
strongly recommend using the new
proxy configuration as below.
New proxy configuration would require the user to add a TOP level parameter
in the axis2.xml named "Proxy".
<parameter name="Proxy">
<Configuration>
<ProxyHost>example.org</ProxyHost>
<ProxyPort>5678</ProxyPort>
<ProxyUser>EXAMPLE\saminda</ProxyUser>
<ProxyPassword>ppp</ProxyPassword>
</Configuration>
</parameter>
Thus, if its a open proxy, user can ignore ProxyUser and ProxyPassword
elements.
In addition to this, if you don't want to go through writing the above
parameter you could use Java Networking Properties for open proxies,
-Dhttp.proxyHost=10.150.112.254 -Dhttp.proxyPort=8080
At runtime, the user can override the PROXY settings using the
HttpTransportProperties.ProxyProperties object. Within your client stub,
create an instance of this object, configure proxy values for it,
and then set it to the MessageContext's property bag via options.setProperty().
For example:
Options options = new Options();
...
HttpTransportProperties.ProxyProperties proxyProperties = new
HttpTransportProperties.new ProxyProperties();
proxyProperties.setProxyHostName(....);
proxyProperties.setProxyPort(...);
...
options.setProperty(HttpConstants.PROXY, proxyProperties);
MG>so you can set proxyPort via axis2.xml OR SpecifyAtCommmandLine OR supply
proxyPort to HttpTransportProperties and then set Options in code
MG>your choice
