I was wondering if running the java app inside a nested X server would
work as a hack to make it behave usably? I presume that the app would
see no window manager and therefore not activate the java WM-specific

I have installed Xephyr (called xserver-xephyr under Debian) to try this
out, but I've not had time to seriously play with it yet. The oddity I
have seen, though, is that dwm rules seem unable to match the xephyr
window when it appears - there seems to be no class:instance:title info
to match against (I patched tag.c to print this info to stderr (as shown
below) - it works fine for all my other clients so far, but prints
nothing for xephyr).

What am I missing? Is this likely to help with the java apps anyway?


settags(Client *c, Client *trans) {
        char prop[512];
        unsigned int i, j;
        regmatch_t tmp;
        Bool matched = trans != NULL;
        XClassHint ch;

        if(matched) {
                for(i = 0; i < ntags; i++)
                        c->tags[i] = trans->tags[i];
        else if(XGetClassHint(dpy, c->win, &ch)) {
                snprintf(prop, sizeof prop, "%s:%s:%s",
                                ch.res_class ? ch.res_class : "",
                                ch.res_name ? ch.res_name : "", c->name);
                fprintf(stderr, "%s\n", prop); // KMW: print new-client info to stderr
                for(i = 0; i < len; i++)
                        if(rreg[i].clregex && !regexec(rreg[i].clregex, prop, 1, &tmp, 0)) {
                                c->isfloat = rule[i].isfloat;
                                for(j = 0; rreg[i].tregex && j < ntags; j++) {
                                        if(!regexec(rreg[i].tregex, tags[j], 1, &tmp, 0)) {
                                                matched = True;
                                                c->tags[j] = True;
                for(i = 0; i < ntags; i++)
                        c->tags[i] = seltag[i];
