1) revise war build process to force inclusion of libs
2) have a server lifecyclelistener that, before loading of a webapp,
copy the concerned classes to the WEB-INF/lib ?
Copy seems easier than play with classloader...
Here is my solution which I tested and it works pretty fine:
1/ in conf/context.xml I put:
<Listener className="foo.FooListener" extDir="${catalina.home}/ext-lib/"/>
2/ I put my foo.FooListener in jar and then in ./server/lib/
3/ source code:
/** FIXME polish, add logging, exception handling, etc */
public class FooListener implements LifecycleListener {
private String extDir;
public String getExtDir() {
return extDir;
}
public void lifecycleEvent(LifecycleEvent event) {
if (Lifecycle.START_EVENT.equals(event.getType())) {
if (event.getSource() != null) {
final StandardContext ctx = (StandardContext) event.getSource();
final File dir = new File(getExtDir());
File[] files = dir.listFiles();
for (int i = 0; i < files.length; i++) {
ctx.getLoader().addRepository("file://" + files[i].getAbsolutePath());
}
}
}
}
/**
* Required configuration parameter.
*
* @param extDir
*/
public void setExtDir(String extDir) {
this.extDir = extDir;
}
}
That's all, it works fine, it does not affect classloader hierarchy
and it is logically equal to copy-based solution.
Thanks for your help, now let's wait what customer say ;)
