Re: [Wala-wala] Fail to build call graph for JDBC driver code

[Stephen F. <sj...@us...>]

Try adding the following code to your program; this forces WALA to process 
the java.sql initialization sequence.  You can substitute whatever driver 
Derby provides for JdbcOdbcDriver().

        static {
                try {
                        java.sql.DriverManager.registerDriver(new 
JdbcOdbcDriver());
                } catch (SQLException e) {
                        e.printStackTrace();
                }
        }

[Wala-wala] Fail to build call graph for JDBC driver code






When we run WALA on derby, the call graph we got doesn't contains any
derby classes.  The harness program(JavaDBDemo.java in attachment) is
very simple, just load JDBC driver via Class.forName(), connect to
data base via DriverManager.getConnection(), perform some operations
and close the connection finally.

Seems WALA works well for reflection, but don't know WALA supports
such case.  Is it a bug in WALA or WALA doesn't support such case at
all?  If WALA doesn't support it, is there any workaround for this
problem?
