You might have a look in the
sar output if your system uses
sar - which may or may not be the case.
Otherwise, you might have some performance monitoring tool running and might find information in its output.
Otherwise, i suppose you are out of luck: you can see the
current swapping - quite detailedly so - in the
vmstat output, but the figures from yesterday are not there (and to my knowledge anywhere saved). In this case you might set up something - log
vmstat to a file, start
sar, etc.. - and wait until the problem occurs again.
I hope this helps.

schemagen
schemagen(1) General Commands Manual schemagen(1)
NAME
schemagen - Java(TM) Architecture for XML Binding Schema Generator Specification Version: 2.0
Reference Implementation (RI) Version: 2.0 ea3
Launching schemagen
The schema generator can be launched using the appropriate schemagen shell script in the bin directory for your platform.
The current schema generator can process either Java source files or class files.
We also provide an Ant task to run the schema generator - see the instructions for using schemagen with Ant.
For Solaris/Linux
% path/to/jaxb/bin/schemagen.sh Foo.java Bar.java ...
Note: Writing schema1.xsd
For WindowsNT/2000/XP
> path ojaxbinschemagen.bat Foo.java Bar.java ...
Note: Writing schema1.xsd
If your java sources/classes reference other classes, they must be accessable on your system CLASSPATH environment variable, or they need
to be given to the tool by using the -classpath/-cp options. Otherwise you will see errors when generating your schema.
Command Line Options
Usage: schemagen [-options ...] <java files>
Options:
-d <path> : Specify where to place processor and javac generated class files
-cp <path> : Specify where to find user specified files
-classpath <path> : Specify where to find user specified files
-help : Display this usage message
Generated Resource Files
The current schema generator simply creates a schema file for each namespace referenced in your Java classes. There is no way to control
the name of the generated schema files at this time. For that purpose, use the schema generator ant task.
