Re: Test Post to Servlet Doesn't Work.
Thank you for your suggestion.
I just tried it but it doesn't perform a connection either. The only difference
between what Hunter is doing in his code and mine is he is using a
DataOutputStream and I am using a PrintWriter which shouldn't make any
difference. He is also using the URLEncoder.encode method for both the name and
value. All the URLEncoder.encode method does is scan the string for reserved and
unsafe characters and replaces them with their URL encodings. This is equivalent
to my line:
out.println( cmd= + URLEncoder.encode( xml ) );
I don't bother to encode cmd because it doesn't have any reserved or unsafe
characters in it. It is producing the same string value as Hunter's
toEncodedString() method.
I am beginning to think I don't have Orion configured properly or my application
deployed properly because all the code examples I see all have the same structure
and others seem to be able to make them work.
Thank you for taking the time to look at my problem.

It looks like you are not properly supplying arguments for POST method
The right order based on Jason Hunter book example is below:
To use it in your case just put your xml string into Properties object
as a value against cmd as a name
public static final InputStream sendPostMessage(Properties args, URL
destination)
throws IOException
{
String argString = ;
if (args != null)
{
argString = toEncodedString(args);
}
URLConnection con = destination.openConnection();
// Prepare for both input and output
con.setDoInput(true);
con.setDoOutput(true);
// Turn off caching
con.setUseCaches(false);
// Work around a Netscape bug
con.setRequestProperty(Content-Type,
application/x-www-form-urlencoded);
// Write the arguments as post data
DataOutputStream out = new DataOutputStream(con.getOutputStream());
out.writeBytes(argString);
out.flush();
out.close();
return (con.getInputStream());
}
/sendPostMessage
private static final String toEncodedString(Properties args)
{
StringBuffer buf = new StringBuffer();
Enumeration names = args.propertyNames();
while (names.hasMoreElements())
{
String name = (String) names.nextElement();
String value = args.getProperty(name);
buf.append(URLEncoder.encode(name) + = + URLEncoder.encode(value));
if (names.hasMoreElements())
buf.append();
}
return buf.toString();
}
toEncodedString
Hope it helps

I have System.out.println's in my servlet code to notify the open

Thank you for your help.

Orion hangs when connections exhausted.
Has anyone experienced Orion hanging when all of the available connections from the pool are exhausted? I noticed a similar question posted by Joel Shellman back in August of 2000 but there was no response to his question. I can re-issue the same URL from a browser multiple times and once the application has taken the last pooled connection it hangs and never returns. Orion never lets go of the connection even after waiting for over an hour. Only way to get Orion working again is to boot. Connections are not being made in an EJB but in regular java classes that are called from a stateless session bean. My application is to be deployed on an Intranet and I expect the traffic to be minimal so a work around is to set up the connection pool with a large enough number of connections so that they are never used up, but Orion shouldn't be hanging. Is this an Orion problem or am I missing something in the data-sources.xml file? Thanks for any help. Milton S. I am running Orion 1.5.2 on NT 2000 Professional against an Oracle 8i database on NT 4.0 server using the Oracle Thin JDBC driver.

And the obvious answer is yes.

Re: Dynamic Loading of a Data Source
I have tried it and it does not seem to work or at least how I am doing it. To test it I have a functioning Oracle data source. I cut this data source out of the \config\data-source.xml descriptor file. I then restart Orion. Orion cannot find the data-source when I run my application. With Orion still running I paste the data source back into the \config\data-source.xml descriptor file and save it, Orion does not pick up the change. Is there some configuration setting that needs tweeking. Do I need to hook into the JNDI? Any advice on how to do this, if it is possible, would be greatly appreciated. Hani Suleiman wrote: Try it!
