classloader - Using JavaCompiler with Classpath referencing jars within ear -


i working on project in enterprise archive (ear) deployed on jboss server needs compile (and run) class dynamically. using javacompiler class - complication comes fact class being compiled has references of classes contained within ejb jar within ear.

this not problem when deployed ear 'exploded' on deployment, directory rather archive - in case able specify required jar in -classpath option of compiler, , compilation works fine. unfortunately due constraints of systems working with, not acceptable solution deploy these ears 'exploded', , compiler seems not able 'see' required jar when it's wrapped in archive.

given dynamic compilation taking place ear in question, , therefore system's class loader has access contents of required jar, there way can tell compiler use classes loaded system class loader?

i appreciate of wordy question, appreciated.

thanks

it seems there no simple way have javacompiler load dependencies of compiled code classloader. however, 1 implement javafilemanager directly , redirect operations standardlocation.class_path using resource lookups on context classloader (getresource(<class/resource name>)). withdraw limitation of standardjavafilemanager directly operating on files.

someone seems have prototypically implemented approch: http://atamur.blogspot.de/2009/10/using-built-in-javacompiler-with-custom.html

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
