How to capture nullpointerexception,ftp connection issues via a log/output file talend job

My talend job is working perfectly now,but i would like to induce some basic quality validation checks and put them in place to capture the error right away without any hassle.So inorder for that i am going to schedule the job to run hourly and if there is some failure due to disk space,FTP connection failure issues,errors due to file parsing name(by splitting the name i will load into db) -So if i run into java IOException****nullpointerexception or something like that.How do i capture the error from console onto the log file in the folder from the talend job which keeps running in the background.

This is the code i am using to write the console output to an file.however i cannot capture the erraneous cases,please advise how to do that:

java.io.File file = new java.io.File("C:/Users/hsivakumar/Desktop/tests/output.txt");

java.io.PrintStream ps = new java.io.PrintStream(new java.io.FileOutputStream(file));

//java.io.File outputFileErr = new java.io.File("C:/Users/hsivakumar/Desktop/tests/outputerr.txt");

System.setOut(ps);

System.setErr(outputFileErr);

I am getting an error when using setErr

You don't need to code in Talend to catch and log Exception. Just drop a tLogCatcher and link its output to a file component.

The tLogCatcher will catch the Exception and populate several fields.

The tFileOutputDelimited will create your log file.
