But Boss

The data is saving properly in the database. The issue is with JTable. I have an updateTable Function, even if i am calling the function, it is not refreshing the data. That is my issue. Infact i have tried also repaint(), but still failing.

I have described the functioanlity such that, you might be able to assume the path/parent frame where the JDialog is opening.

Thanks/Regards

Dear Ranchers

I am preparing a small solution. Below is how the functionality works.

1. Login Screen
2. Successful Login will take to a MDI Form
3. Click the menu, a JInternalFrame will open in the JDestopPane.
4. JInternalFrame has a JTable.
5. JInternalFrame has a JButton available for adding new data.
6. When JButton is clicked, a new JInternalFrame is popped up with some JTextField and JButton to save the data.
7. After saving the data (after insert query), a JDialog is opened to upload Logo (update query for BLOB), There are two buttons in the JDialog, one is for uploading the image, another one is uploading it later.
8. The logo is displayed in the JDialog and if the JButton, for upload is pressed, update the database and reload the JTable in the JInternalFrame is called.

My challenge is in point 8. The function is called properly, but the table is not getting refreshed.

Below provided my code, can you please help to understand where i went wrong.

Dear Ranchers

Happy New year!!

I am in the process of developing a JSP Web application, with frame sets and iframes. The purpose of using the frame set and iframe is the page remains same throughout the application (egs: Header, left panel menu, footer) and the content part will the only one changing.

Now, I have in my web.xml, I have the session time out set to 10 minutes.



My challenge, if I left the web page idle for more than 10 minutes, the session is getting invalidate and when I come back and click any link in the left menu/content page, the iframe or content frameset is only giving the session time out message and not the whole page.

Please give me an idea to resolve this.

Thanks/Regards

Hi Ramesh

I am calling this function from another class.

When i run this, i can see the values are actually passing in System.out.println.

But the actual JTextField (countryName) is not displaying any field.

Dear Ranchers

I am trying to send a value from one class to another class in Java Swing.

I wanted to display a string value in the JTextField and unfortunately I am failing to do that. But the getText() is displaying the answer well.

Below is the code and kindly help me understand where the problem is.



The function test() is the one giving the problem.

public void test(String ctryName)
{ System.out.println("I have reached here" + ctryName);
System.out.println("Before Updating: "+ countryName.getText());
String abc = ctryName;
countryName.setText(abc);
jTextField3.setText(abc);
System.out.println("Text is: "+ countryName.getText());
}


Awaiting your usual prompt support.

It is not actually sending the html tag. May be a limitation in the webpage.

I am sending the screen shot of the same.

Dear seetharaman

Thanks for the feedback.

I tried no-wrap before and if i put, the information is streatching the table and it is becoming un-tidy. The only option is to display few characters.

The solution in my mind is

1. get the value in the string.
2. make substring
3. display the sub-string.

I am not sure whether the above login is correct or is there any easier way to sort this out.

Thanks/Regards

Dear Ranchers

I have to provide a tabluar view of the data retreiving from the database table. One column has a long description of the data where by i have provided 50% width for it. Once it is exceeding the 50% width, the information is going to the next line (like WRAP Text) which is making my display un-tidy.

I would like display only the information with 40 characters, so that all the table rows will look perfectly.



Attached here with the sample output of the table. Please look at line number 37

Please let me have a solution for this.

Thanks/Regards
