ESB Client API - unable to connect to ESB.

Question

Hi,
I am exploring ESB Client APIs. As a first step, I need to get the Console client. But I am not able to connect, and am instead getting 404 error. Here is the code
bq.      package esbclientapi; \\     import oracle.tip.esb.client.ConsoleClient; \\     import oracle.tip.esb.client.ConsoleClientFactory; \\     public class BasicTest { \\      private String _host = "localhost"; \\      private int _port = 80; \\      private String _username = "oc4jadmin"; \\      private String _password = "welcome1"; \\      private void load() throws Exception { \\      System.out.println("Try to connect"); \\      ConsoleClient client = \\      ConsoleClientFactory.getConsoleClient(_host, _port, _username, \\      _password); \\      System.out.println("DVMLoader.load(): Got client"); \\      } \\     public static void main(String[] args) { \\      try { \\      BasicTest ldvm = new BasicTest(); \\      ldvm.load(); \\      } catch (Exception e) { \\      e.printStackTrace(); \\      } \\     } \\     } \\
Here is the error \\bq.      Try to connect \\     oracle.tip.esb.client.ClientException: 404 : Not Found \\     at oracle.tip.esb.client.HttpClient.invoke(HttpClient.java:118) \\     at oracle.tip.esb.client.HttpClient.handleRedirectRequest(HttpClient.java:193) \\     at oracle.tip.esb.client.HttpClient.postAndReceive(HttpClient.java:147) \\     at oracle.tip.esb.client.HttpClient.invoke(HttpClient.java:114) \\     at oracle.tip.esb.client.impl.ConsoleClientImpl.authendicate(ConsoleClientImpl.java:102) \\     at oracle.tip.esb.client.impl.ConsoleClientImpl.<init>(ConsoleClientImpl.java:73) \\     at oracle.tip.esb.client.ConsoleClientFactory.getConsoleClient(ConsoleClientFactory.java:32) \\     at esbclientapi.BasicTest.load(BasicTest.java:15) \\     at esbclientapi.BasicTest.main(BasicTest.java:25) \\     Caused by: java.io.IOException: 404 : Not Found \\     at oracle.tip.esb.client.HttpClient.throwException(HttpClient.java:223) \\     at oracle.tip.esb.client.HttpClient.postAndReceive(HttpClient.java:150) \\     at oracle.tip.esb.client.HttpClient.invoke(HttpClient.java:114) \\     ... 8 more \\     Process exited with exit code 0. \\     
Env Info:\\ I am using SOA 10.1.3.4. which has been installed over the advanced installation of SOA 10.1.3.1. I am using Jdev 10.1.3.4 \\ So, to access the ESB console, I simply use [http://localhost/esb] \\ To compile this program, I added Oraesb_patch.jar and xmlparserv2.jar to Libraries in JDeveloper \\ I guess the issue is with the hostname. I tried using the actual hostname, but it didnt help. To figure out the actual hostname, I looked at wsdl of one of the services which looks like this: \\[http://xxxx.yyyy.local:80/orabpel/default/SetPollingFreqForDBAdapter/1.0/SetPollingFreqForDBAdapter?wsdl|http://esswsl020-w209.emrlab.local/orabpel/default/SetPollingFreqForDBAdapter/1.0/SetPollingFreqForDBAdapter?wsdl] \\ So I tried using xxxx.yyyy.local, but got same error. \\ However, I feel the issue is something else. I tried giving some dummy string as host, and got a different error \\bq.      private String _host = "ddd"; \\
error I got: \\bq.      Try to connect \\     oracle.tip.esb.client.ClientException: ddd \\     at oracle.tip.esb.client.HttpClient.invoke(HttpClient.java:118) \\     at oracle.tip.esb.client.impl.ConsoleClientImpl.perform(ConsoleClientImpl.java:148) \\     at oracle.tip.esb.client.impl.ConsoleClientImpl.<init>(ConsoleClientImpl.java:71) \\     at oracle.tip.esb.client.ConsoleClientFactory.getConsoleClient(ConsoleClientFactory.java:32) \\     at esbclientapi.BasicTest.load(BasicTest.java:17) \\     at esbclientapi.BasicTest.main(BasicTest.java:27) \\     Caused by: java.net.UnknownHostException: ddd \\     at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:177) \\     at java.net.Socket.connect(Socket.java:507) \\     I noticed that the error came in HttpClient.invoke \\     itself, a step which went off fine earlier (as per the earlier stack trace). \\     So my question is, how should I figure out the hostname.

Answer 1

I decompiled HttpClient and ConsoleClientImpl and this is what I found --- The following URL is what is constructed,
http://localhost:80/esb/j_security_check and these parameters are passed as POST - j_username=oc4jadmin&j_password=welcome1
I tried
http://localhost:80/esb/j_security_check?j_username=oc4jadmin&j_password=welcome1
and got 404 error.
However, this exercise confirmed that hostname=localhost and port=80 is just fine.. the problem seems to lie somewhere else
