I have NetBeans 7.01 from Debian repository - all works. But I have a problem with NetBeans 7.3 from the official site (installed on the same machine) - I can't compile anything:ERROR - Ant is misconfigured and cannot be run.  java.lang.ClassNotFoundException:  org.apache.tools.ant.module.bridge.impl.BridgeImpl at  java.net.URLClassLoader$1.run(URLClassLoader.java:366) at  java.net.URLClassLoader$1.run(URLClassLoader.java:355) at  java.security.AccessController.doPrivileged(Native Method) at  java.net.URLClassLoader.findClass(URLClassLoader.java:354) at  org.apache.tools.ant.module.bridge.AntBridge$MainClassLoader.findClass(AntBridge.java:647)  at java.lang.ClassLoader.loadClass(ClassLoader.java:423) at  java.lang.ClassLoader.loadClass(ClassLoader.java:356) at  org.apache.tools.ant.module.bridge.AntBridge.createAntInstance(AntBridge.java:299)  at  org.apache.tools.ant.module.bridge.AntBridge.getAntInstance(AntBridge.java:279)  at  org.apache.tools.ant.module.bridge.AntBridge.getInterface(AntBridge.java:268)  at  org.apache.tools.ant.module.run.TargetExecutor.run(TargetExecutor.java:541)  at  org.netbeans.core.execution.RunClassThread.run(RunClassThread.java:153)Lubuntu x32, all updates.
