Look in your AndroidManifest.xml and make sure that your main activity is registered (in your case MyHTTPD). Heres a very basic manifest file, take a look at the tag. I put in your class as an entry.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.epstest"
android:versionCode="1"
android:versionName="1.0" >
....
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >

<activity
android:name="dolphin.developers.com.MyHTTPD"
android:label="@string/title"
android:configChanges="orientation" >
