This seems the problem in version of commons validator jar. Could you please give me the version of the struts that you are using.

What is the value for parameter author you are passing. Author is not having any space so author.indexOf(' ') is returning -1. So it is giving IndexOutOfBoundException in next line.

Value for the 'isELIngnored' is false only from Servlet 2.4. I believe you are using Servlet 2.3 DTD in your web.xml. Change it to '2_4' then it will take false as default value.

Please send me full question..

See this link http://docs.codehaus.org/display/AW/Tutorials. It will guide you to write a simple aspect oriented code in Java using Aspectwerkz.

Add the following bolded line in your code. If you get "Values: true" in your JSP then you are getting data from table else you are not.

Class.forName ("com.mysql.jdbc.Driver").newInstance(); Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/conference", "meetme", "meetme"); Statement st = conn.createStatement(); ResultSet rs=st.executeQuery("select * from meetme"); [B]out.println("Values:" + rs.next());[/B] while(rs.next())

I think you are getting some exception and suppressing the same.Please add the following code inside the catch block in your JSP and confirm there is no any exception in executing the query.

e.printStackTrace(new PrintWriter(out));

String encodedURL = URLEncoder.encode("ClientQuerySearchAction.do?modulePer=92.7%&clientCode=111" , "UTF-8");

Use encodedURL. Then it should work..

It is not a special functionality of IOException.

IOException is an Checked Exception.
ArithmethicException, NullPointerException etc are Unchecked Exception.

You cannot put the catch block for Checked Exception unless some method calls of try block or try block throws the same exception.

In your code try block contains only myref.test() but it is not throwing IOException, So it fails..

Yes it is valid method and it will return you the scope where the attribute has been set with that particular name.

It is available in PageContext.

Can you give us some more details. What is your question ?

Congrats..

Great Score

"varstatus" attribute in forEach will give you an index of the element in iterating List.


For first iteration its value will be 1
For second iteration its value will be 2..

Variable sb is not yet initialized, default value will be null. So you are getting null pointer exception. Replace the sb declaration with following code.Then it should work
private static StringBuffer sb = new StringBuffer();

What is the output that you are expecting from the above code ?

It is working fine.

int[] arr = {1,2,3,4,5,6,7,8}; for (int i : arr){ // Here i is not an index. It is the value in the particular location arr[i] = 0; }
So for

First Iteration

i = 1

a[1] = 0

array = {1,0,3,4,5,6,7,8}

Second Iteration

i=0

a[0] = 0

array = {0,0,3,4,5,6,7,8}

Third Iteration

i=3

a[3]=0

array = {0,0,3,0,5,6,7,8}

...
..
...

After completing the eight iteration value in the array will be
{0,0,3,0,5,0,7,0}
