unable grab jsonmappingexception 6 answers

i new jackson, have written code , ide says @ grab block . dont understand . have included jar.

incompatible types required:java.lang.throwable found :org.codehaus.jackson.map.jsonmappingexception

this method

private void jacksontest() { seek { org.codehaus.jackson.map.objectmapper mapper = new org.codehaus.jackson.map.objectmapper(); mapper.writevalue(new file("c:\\user.json"), someobj); } grab (ioexception ex) { logger.getlogger(gr_xx.class.getname()).log(level.severe, null, ex); } grab (jsonmappingexception ex) { // incompatible types // required:java.lang.throwable // found :org.codehaus.jackson.map.jsonmappingexception } grab (exception ex) { logger.getlogger(gr_xx.class.getname()).log(level.severe, null, ex); } grab (throwable ex) { logger.getlogger(gr_xx.class.getname()).log(level.severe, null, ex); } }

as can see in documentation of jsonmappingexception, subclass of ioexception. means first catch handle jsonmappingexception. if want handle seperately, you'll have grab before ioexception.
