jdb is the Java debugger that comes with the jdk.
When you start your java program, you tell the jvm to
give you a password so you can log into it once it's
already running. The client is jdb.
This is what I remember from the last time I did it:
1) Use
java_g -debug <class>
this prints your jdb password to stdout, e.g. 32d8y9
2) Use
jdb -host <hostname> -password <password>
Once you are inside the jvm it looks a lot like a C debugger.
To see where the threads are hanging, use the commands explained
in the document
<jdk>/docs/tooldocs/solaris/jdb.html
You will have to a) list the threads b) select one thread c) print
the stack trace.
3) If your are using native libraries you need to create a debug
copy of each library, e.g.
cp liboci7jdbc.so liboci7jdbc_g.so
This is explained in
<jdk>/docs/tooldocs/solaris/java_g.html
