What you're doing is fine, and is probably working correctly. Modify
MyStartClass so that when it catches a JessException, it displays not
only the top-level exception, but any nested exception as well, as
shown in this clip from jess.Main:
catch (JessException re)
{
if (re.getNextException() != null)
{
m_rete.getErrStream().write(re.toString());
m_rete.getErrStream().write("\nNested exception is:\n");
m_rete.getErrStream().println(re.getNextException().getMessage());
re.getNextException().printStackTrace(m_rete.getErrStream());
}
else
re.printStackTrace(m_rete.getErrStream());
}
The nested exception may tell you why the IOException is occurring. It
can be anything that causes the batched file to not parse correctly,
including syntax errors, missing definitions, etc -- not just that the
file was not found.
