BlackBerry API - SMS - DatagramConnection.send() hangs/freezes

Problem:

public void SendSMS(String input){
   try {
      DatagramConnection dgConn;
      dgConn = (DatagramConnection)Connector.open("sms://15195555555");
      byte[] data = input.getBytes();
      Datagram dg = dgConn.newDatagram(dgConn.getMaximumLength());
      dg.setData(data, 0, data.length);
      dgConn.send(dg); <------  hangs right here!!!! and no Throwable was ever thrown!!!
   } catch (Throwable t) {
       t.printStackTrace();
   }
}

Solution:
Check the length of the message, in my case, it hangs when the message is >160 in length.

Server Tomcat v6.0 Server at localhost was unable to start within 45 seconds. What if the server requires more time?

Problem: Debugging a web app on Tomcat within Eclipse that takes more than 45 seconds to start-up, which prompts the following message:

Server Tomcat v6.0 Server at localhost was unable to start within 45 seconds. If the server requires more time, try increasing the timeout in the server editor.

Solution: I'm not sure where the server editor is located, but changing the start-timeout="45" in workspace\.metadata\.plugins\org.eclipse.wst.server.core\server.xml would help, make sure restart eclipse after the change.

VMWare connects at 10Mbps

Problem: After the weekend, my VMWare's XP(AMD PCNET Family PCI Ethernet Adapter) connects to the network at 10Mbps, while it was connecting at 1Gbps before the weekend.


Solution: Check the VMWare's MAC address, let your administrator know if the address has been updated. Secondly, reinstall/repair VMWare Tools.

Disabling hotmail ads

Problem; Hotmail's ads on the side sometimes has the semi-porn like graphics, which isn't very appropriate at work, especially when the supervisor just walked by and thought the employee is surfing porn sites.

Solution: edit the \windows\system32\drivers\etc\hosts file, add the following lines(or whatever domains that host the ads)

127.0.0.1 ads1.live.com
127.0.0.1 rad.live.com
127.0.0.1 live.rads.live.com
127.0.0.1 ads1.msn.com
127.0.0.1 rad.msn.com
127.0.0.1 live.rads.msn.com
127.0.0.1 view.atdmt.com

Caused by: java.util.MissingResourceException: Can't find resource for bundle java.util.PropertyResourceBundle

Problem: keeps getting exception of a missing key from ResouceBundle

Caused by: java.util.MissingResourceException: Can't find resource for bundle java.util.PropertyResourceBundle, key low_battery_notification

Solution: Check the spelling and make sure the key is case-sensitive.
Turns out that low_battery_notification wasn't there, but low_Battery_notification was.
