I learned that sar is great! ( but sars is bad )

How do I do that Java 101 task again?...

I find that every new Java project I'm on, I run into a situation where I want to translate an InputStream to a String or vice versa. This is frequently in a unit test where I've read an input file or expected output file in using getClass().getResourceAsStream() and need to convert to Strings for use in my test.

It's a simple boiler plate task, yet darned if I can remember the most an effecient way to do it every time. I always re-google and always tend to refer to this one to jog my memory..

Thought I'd link out to it this time.

POM Search Site

I know this is obvious, but adding it I can reference in the future...

Get dependency tags for dependencies.

Hibernate shows SQL to log4j too

Log hibernate queries and more without using the show_sql = true setting in your hibernate config. This way you can see them in your log4j configured log files, not just in your STDOUT log.

# Hibernate logging
# Log everything (a lot of information, but very useful for troubleshooting)
log4j.logger.org.hibernate=FATAL
# Log all SQL DML statements as they are executed
log4j.logger.org.hibernate.SQL=DEBUG
# Log all JDBC parameters
log4j.logger.org.hibernate.type=INHERITED
# Log all SQL DDL statements as they are executed
log4j.logger.org.hibernate.tool.hbm2ddl=INHERITED
# Log the state of all entities (max 20 entities) associated with the session at flush time
log4j.logger.org.hibernate.pretty=INHERITED
# Log all second-level cache activity
log4j.logger.org.hibernate.cache=INHERITED
# Log all OSCache activity - used by Hibernate
