I have created a job in talend studio to execute a query(query execution takes 5-10 minutes) and write the data into excel file.
I have build the job as
1. standalone job and
2. Axis webservice(WAR)
Standalone job works perfectly, creates excel file from query every time when run.
But, webservice(WAR) deployed in tomcat server sometimes work correctly but, sometimes it starts to create 0 KB file. This issue is intermittent and sometimes it gets resolved with server restart. When 0 KB file is created then all next runs create 0 KB file
I have placed components to log message before executing the query and after creating excel file.
Only log message before executing query is printed and 0 KB file is created.
Could you please indicate on which talend build version you got this issue?
Are you tomcat running well? Did your deploy your job war file successfully?
Yes war file is deployed successfully.
Before executing the query I have logged that 'query is getting executed' and it is getting printed successfully. But, after executing the query log message is 'Excel file has been generated successfully', and it is not getting printed in log file and 0 KB file is created.
Have you tried to choose 'Axis webservice(zip)' and place the relevant Class from the ZIP (or unzipped files) into the relevant location, of your Web application server to see if it works?
What's return code from the Web application? The return code from the Web application is 0 when there is no error and 1 if an error occurs.
