No stacktrace at all. Using the old-fashioned System.err.println()
method of debugging (I don't know of any other way to do it on the
test server) I was able to determine where one of my errors is coming
from. While, yes, the database connection was failing but it was
because an earlier call to a method is another class hung, crashed,
I'm not sure which. The entire class is very short so here's the
source (including my print statements):
package org.linfield.accountRequest.server.workers;
import java.io.IOException;
import java.net.URI;
import java.net.URISyntaxException;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.ParseException;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.client.utils.URIUtils;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.util.EntityUtils;
//import org.apache.xerces.util.URI;
//import org.apache.xerces.util.URI;
public class FerpaRetrieval {
public FerpaRetrieval() {
// TODO Auto-generated constructor stub
System.err.println("Instantiate FerpaRetrieval()");
}
public String getPolicy() {
try {
System.err.println("Trying FERPA"); <----
this statement
appears in catalina.out
HttpClient client = new DefaultHttpClient();
System.err.println("Made a client"); <----
this statement
does not
URI auth = URIUtils.createURI("https",
"www.linfield.edu",
-1, "its/ferpa/ferpatext.html", null,
null);
System.err.println("Got past URI");
HttpPost ap = new HttpPost(auth);
HttpResponse response = client.execute(ap);
String policy = "";
HttpEntity entity = response.getEntity();
System.err.println("Got past getEntity");
if (entity == null) {
System.err.println("entity is null");
} else {
policy = EntityUtils.toString(entity);
}
System.err.println("Ready to return FERPA");
return policy;
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return null;
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return null;
} catch (URISyntaxException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return null;
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return null;
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
return null;
}
}
}
The line "HttpClient client = new DefaultHttpClient()" appears to be
the culprit. You'll notice that I included the whole getPolicy()
method within a try/catch to try and catch the problem and get me a
stacktrace. Didn't get anything. Any ideas about this one?
