我想在Talend中写入DB时执行事务,但不知道如何.我从调色板尝试了各种组件,但无法设法执行.我将不胜感激任何帮助,甚至更好的任何与此主题相关的教程.
谢谢!

如何将java字符串转换为Date对象
在我的Java代码中,我输入了String 05.10.2011,我需要将其转换为毫秒.
所以:
String someDate = "05.10.2011";
我必须转换为匹配毫秒格式.
我正在尝试从我的应用程序打开网页这么简单.我认为代码应该看起来像下面的东西,但我在执行代码时不断收到错误"找不到任何活动":
public class MainActivity extends Activity {
public static final String MY_STRING = "com..example.MY_STRING";
Button button1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(clickListener);
}
public OnClickListener clickListener = new OnClickListener(){
@Override
public void onClick(View arg0) {
Intent launchBrowser = new Intent(Intent.ACTION_VIEW, Uri.parse("www.example.com"));
startActivity(launchBrowser);
}
};
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
这是日志:
