you cannot throw-catch between process boundaries. have use inter-process communication technique. there many of them choose depending on situation.

here list of options...

1. file: process writes log file process b listening to. easy implement.
2. named pipes or tcp/ip sockets: can link 2 processes named pipe or sockets , transmit data on wire 1 application another.
3. message queue: process can listen message queue process b pushing messages to.
4. database: process can write database while process b checks database. remote database or simple sqlite database.

using file or named pipe easiest way go trying solve. other options depend on environment , requirements.
