Exception when running samples

[Christina]

Hi Raj,

I am new in mashups....
I am running Windows Server 2003. I downloaded and installed java 6
and tomcat 5.5.28 (both running ok) but when i am trying to run any of
the samples (based on the instructions provided) i get the following
error:
C:\Program Files (x86)\apache-tomcat-5.5.28\webapps\emml\WEB-INF
\classes>java emmlclient http://localhost:8080/emml/rssfilter
Invoking URL: http://localhost:8080/emml/rssfilter
Exception in thread "main" java.io.IOException: Server returned HTTP
response code: 500 for URL: http://localhost:8080/emml/rssfilter
at sun.net.www.protocol.http.HttpURLConnection.getInputStream
(HttpURLConnection.java:1313)
at emmlclient.main(emmlclient.java:24)

I would really appreciate any help on that.

Many thanks
Christina

Hi again,

I just remembered that I am using Proxy to connect to the internet...
So, i modified the emml.config file which now looks like this:

service.timeout=20000
httpProxy.enable=true
httpProxy.host=js000525
httpProxy.port=8080
httpProxy.user= 'my user name'
httpProxy.password= 'my password'
httpProxy.credentialsType=
httpProxy.ntDomain=
httpProxy.bypassIPList=127.0.0.1
httpProxy.bypassHostList=localhost
httpProxy.bypassDomainList=

So, now when i start tomcat i dont get the previous error and the log
is as follows:

Ok, I think I found what the problem is...
the emml.config file was not at the correct folder
So, now when i type 'http://localhost:8080/emml/twitter' on the
browser i get something like that:
<?xml version="1.0" encoding="UTF-8"?>

etc etc etc

</ul>

I guess this is not the expected output but at least I know what the
problem is....the proxy's authentication.
Am i correct?

However, the Tomcat's log still gets some errors probably due to
invalid authorisation:

i guess this is what i should expect..isn't it?

however i still get an error (tomcat's log) which is: 2009-10-26
14:27:56,293 ERROR [HttpProxyManager.class] - <Invalid server
URL...using given value as server host> (at least is only 1 line)

I would appreciate any feedback.

Regards,
Christina

Ya, cool - you are seeing the twitter search results in response.  

Regarding the specific error, please ignore that - it's spurious/ harmless.
