Ok this is what I'm going for -
I wrote a simple java applet framework. The applets need to be signed. So I
made an Ant file which handles signing the applet and combing all support
libraries for the end user. But I'd like a section at the top of my Ant
script where the user can list any additional jars they require, so I can
take that into account of my signing routine for them. So a comma delimited
string would be fine, something like:
// User gives me one string with paths to all jars they need.
<property extra_jars="C:/jarA.jar,C:/testing/jarB.jar,C:/help/jarC.jar">
// I have to tokenize it and sign each one for them:
for (extra_jars) {
sign(nextJar);
}
// I have to create an index.html file for them which houses the applet
// and points to each of those jars.
<filewrite="<applet archive="/>
for (extra_jars) {
<filewrite="${nextJar}"/>
}
// Now I'll copy each one into an export directory.
// ...
Yeah the above is all pseudo-code of course but it gives the idea of what I
want to do. Right now I've just hard-coded the jars being used. Everything
works, it's just that it'd be much nicer to let the user specify one comma
delimited string up top, I parse it and do the rest of the magic for them.
Thanks,
Mark
