Re: Strange Error after invoking a service the second time
Hi Deepal & others,
Thanks for your answer. Actually, i don't know what JIRA is. I looked at
their Webpage, but i need to install that software? I will try that later
and look how i can create a project, but it seems like i have to get
familiar to that before.
Meanwhile i found out more about my project. It seems like only one
Webservice is somehow faulty. (the one that is called by the other). That is
a web services which accesses the Pubmed web service. The Pubmed web service
is an AXIS 1.3 service, and mine, which accesses the Pubmed, is AXIS2 1.3.
Could there be a problem? I generated in my AXIS2 project java code (fot the
stub) by using AXIS1 wsdl2java utility. And copied the axis.jar (axis
1.3jar file) to the tomcat project axis2/WEB-INF/lib.
Now, this works. But after i access my web service the first time, it works.
It is although affecting the other web services. Version is not working any
more. Mine is although working. Strange...
The error i get is
[INFO] Unable to sendViaPost to url[
http://localhost:8080/axis2/services/Version]
org.apache.axis2.AxisFault: Transport error: 501 Error: Not Implemented
My service is then unavailable
Error: Service unavailable!
The server is temporarily unable to service your
request due to maintenance downtime or capacity
problems. Please try again later.
(503)Service Unavailable
at org.apache.axis.transport.http.HTTPSender.readFromSocket(HTTPSender.java
:744)
What could i do wrong?
It is obviously that the problem is from AXIS1 1.3, or?
My code acessing Pubmed Web service is the following:
package de.fraunhofer.isst.dortmund.burns.queryhandler.handlers.pubmed;
import gov.nih.nlm.ncbi.www.soap.eutils.EUtilsServiceLocator;
import gov.nih.nlm.ncbi.www.soap.eutils.EUtilsServiceSoap;
import gov.nih.nlm.ncbi.www.soap.eutils.esearch.ESearchRequest;
import gov.nih.nlm.ncbi.www.soap.eutils.esearch.ESearchResult;
import java.rmi.RemoteException;
import javax.xml.rpc.ServiceException;
public class ESearch {
public static String eSearch(String searchString) {
String antwort = "";
try {
EUtilsServiceLocator service = new EUtilsServiceLocator();
EUtilsServiceSoap utils = service.geteUtilsServiceSoap();
// call NCBI ESearch utility
// NOTE: search term should be URL encoded
ESearchRequest parameters = new ESearchRequest();
parameters.setDb("pubmed");
parameters.setTerm(searchString);
parameters.setRetMax("15");
ESearchResult res = utils.run_eSearch(parameters);
// results output
antwort+= "Database used: "parameters.getDb();
antwort+="Found: " + res.getCount()+ " results.";
} catch (RemoteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ServiceException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return antwort;
}
}
All other code is generated by AXIS1 1.3
Thanks again & if you think you can help me, i will create an JIRA project.
