[Soot-list] using soot within an eclipse plugin

[Jennifer Lhotak]

Hi,

In your Approach #1:

Do you get a message from Soot saying something like: Exception in thread
"main" java.lang.RuntimeException: couldn't find class: ... (is
your soot-class-path set properly?) ? If so, then Soot is being invoked
with no problems, but it doesn't know where the class you want to load is.

It sounds as if you need to explicitly set the Soot classpath, before you
call loadClassAndSupport() so you could say something like

Options.v().set_soot_classpath(your_classpath)

where your_classpath is a
string and includes the path to your class in Eclipse. You should be able
to find the path to your class programmatically from within Eclipse using
the resources api.

Note that the string your_classpath will probably also need to include a
path to the java library, which can also be found programmatically from
within Eclipse.
