HO to catch runtime exceptions in Talend

[Anonymous]

Hi,

I need to capture run time exceptions and write into file.

More precisely I need to capture java exceptions, eg error given below,

Exception in component tSalesforceOutput_2
java.lang.Exception: unable to obtain exclusive access to this record

    at org.talend.salesforce.SforceManagementImpl.update(SforceManagementImpl.java:416)
    at talend_main.a_corporate_td_to_sfdc_0_1.a_corporate_td_to_sfdc.tMysqlInput_1Process(a_corporate_td_to_sfdc.java:8977)
    at talend_main.a_corporate_td_to_sfdc_0_1.a_corporate_td_to_sfdc.tSalesforceConnection_1Process(a_corporate_td_to_sfdc.java:9592)
    at talend_main.a_corporate_td_to_sfdc_0_1.a_corporate_td_to_sfdc.tWarn_6Process(a_corporate_td_to_sfdc.java:10081)
    at talend_main.a_corporate_td_to_sfdc_0_1.a_corporate_td_to_sfdc.runJobInTOS(a_corporate_td_to_sfdc.java:18737)

Add a subjob dedicated to catch exceptions, errors and warning:

Events are catched, you don't have to connect the subjob to anything.

In tLogCatcher, select the event type(s) to be catched.

Use tMap to arrange the output format as desired.

 Push the result to a tFileOutputDelimited.

Thanks for explaining. but its not quite clear to me. Could you please elaborate more

In fact, if you know Java, the tLogCatch is like :

try {

   ... your code from your Talend components ...

catch(java.lang.Exception e) {

    ... flow of the error catched. For example, you tMap it to put it into a log file

}

Hope it helps you.
