Using DDD with JDB

There is no automatic data display in JDB. As a workaround, DDD uses the dump command to access data values. This means that variable names are interpreted according to the current frame; variables outside the current frame cannot be displayed.

In JDB 1.1, the dump and print commands do not support expression evaluation. Hence, you cannot display arbitrary expressions.

Parsing of JDB output is quite CPU-intensive, due to the recognition of asynchronous prompts (any thread may output anything at any time, including prompts). Hence, a program producing much console output is likely to slow down DDD considerably. In such a case, have the program run with -debug in a separate window and attach JDB to it using the -passwd option.
