Pass connection object to Talend job from Java program

[Anonymous]

We gave a try to pass connection object form Java program to talend job and found a way to do the same.
Any talend job will have two hash map namely globalMap(private) and parentContextMap(public).
To pass the object we wrote a wrapper class which will inturn extend the original talend job.
Java wrapper class:
public class wrapper extends FetchCustomer_Mainjob{
public static void invokeJob(){
parentContextMap.put("conn_tOracleConnection_1",Util.getConnection());
String[] contextParam = {.....}
String[][]=runJob(contextParam);
}
}

FetchCustomer_Mainjob:
tJavaRow -->tOracleInput--->tMap--->tOracleOutput
Code in tJavaRow:
globalMap.put("conn_tOracleConnection_1",parentContextMap.get("conn_tOracleConnection_1")
com.common.ThreadLocalMap.put("conn_tOracleConnection_1",parentContextMap.get("conn_tOracleConnection_1"));

FetchCustomer_SubJob1:
tJavaRow -->tOracleInput --->tFileOutputExcel
Code in tJavaRow:
com.common.ThreadLocalMap.put("conn_tOracleConnection_1",parentContextMap.get("conn_tOracleConnection_1"));
globalMap.put("conn_tOracleConnection_1",com.common.ThreadLocalMap.get("conn_tOracleConnection_1"));
Clear the ThreadLocalMap values in main job success/error.
Committ the transaction in talend job or in java code based on your businesss conditions.
