Hi,everyone.could you tell me how to make this performance below?

I hope a good idear.

Hardik，thank you for you reply. but I had made it by another method.

I use webView.loadDataWithBaseUrl("",data,"text/html","utf-8",null) to display a html code,
but there is nothing to display,just a white background.
are there any body know what happen?
html code like "<p>hello world..</p>"

You may have a look at this:http://developer.android.com/guide/topics/providers/content-providers.html

There are some codes below:(just for test)
String username = 'Tom'; // variable，not always Tom session.setAttribute('name',username); session.setAttribute(username+'abc','value');
How can i get 'value' in another page to use EL?

I test your expression ,it's ok. what's wrong?

you can use map like this:
public static void main(String[] args) { ArrayList<String> al = new ArrayList<String>(); //init first,just for test al.add("aaa"); al.add("bbb"); al.add("ccc"); al.add("aaa"); al.add("ccc"); Map<String,Integer> map = new HashMap<String, Integer>(); for(int i=0;i<al.size();i++){ Integer count = map.get(al.get(i)); map.put(al.get(i), count==null?1:count+1); //auto boxing and count } System.out.println(map); }

Thanks .
I have made it.
just like
String[] codes = {..........} String sql = "select ....... where code=?" Preparestatement pst = cn.prepareStatement(sql4); for(int i=0;i<codes.length;i++){ pst.setString(1, codes[i]); pst.addBatch(); } pst.executeBatch();

String sql[] = {sql1,sql2,sql3,sql4}; for(int i= 0;i <sql.length;i++) { ps = conn.prepareStatement(sql[i]); ps.addBatch(sql[i]); } ps.execute();
can i use it like this codes?
how to use it . please help me?

you can't. you can't get an Instantce of a abstract class or method. abstract methods are only declared but not implmented.
if you use static key word, can you call a method like:" public void method(); " without Methods body?
so you can do nothing like "ClassName.method()"

thanks . I make it .

just print a message to test whether your code have executed or use debug.
check the value of "n_id" and session.getAttribute("new_notice") after you set Attribute

thanks to Sudhakar Sharma .
now ,it,s works well as my thought

I defined my own filter to do something, but I can't touch off it.
I test agian and again ,finally I find when I use forward jump I can't access the filter, but redirect is normal.
how to solve it. help!

thanks. It's hard to read a so long English artical. and I think it's a little complex. I'll keep to finish it.
thanks again.
