ale já vím, prostě musím udělat stránku, kde budou rámy.
je mi jasný proč to nejde. Je to kvůli tomu, že definovaná třída java.net.URL to jednoduše neumí, jako každá jiná třída v javě, ale přece to nějak musí jít, pokud máte nějaký nápady, tak mi dejte vědět. Jinak jsem zkoušel všemožně target v html, php funkcí, javascriptem i v css a nic prostě nefungovalo..
