connection broken error during installation

[cervisias]

hi all together

i have some troubles with the installation of activiti. i typed "ant demo.start" into the command prompt and it started working…but then the trouble began…

ant (apache-ant-1.8.2) and java (jdk1.6.0_25) versions are working correctly…

does somebody see the matter here?
