Scheduling a java program using another java program -

-

as part of automation want schedule java program after 12 hours using java program running. client machine windows. can't when first script start , once ends, has schedule second script should start after 12 hours. suggestions on how it?

i use java.util.timer.schedule(timertask task, long delay). task schedule can invoke second java program appropriately. example:

public void scheduletask() {     timer timer = new timer();     timer.schedule(new timertask() {         public void run() {             try {                 runtime.getruntime().exec("java secondprog.class &");             } catch (ioexception e) {                 // todo auto-generated catch block                 e.printstacktrace();             }         }     }, 12*1000*60*60);  }

-
i using tfs's team explorer manage visual studio projects. recently, i've created new java project (not in visual studio) manually added tfs using source control control explorer in visual studio. after added java project tfs, made changes , bug fixes. then, went visual studio , opened source control explorer check in changes, tfs thinks no changes made. it seems needed check out project before making changes. guess erroneously expected tfs track automatically, okay. so, using source control explorer in tfs, checked out project, , tried check in pending changes. when tried check in, got following message: all of changes either unmodified files or locks. changes have been undone server. is there way convince server indeed project has changed? how can check in changes have made? thank help.
