Thank you Michael for the response.

Michael Angstadt wrote:javac doesn't use the JAVA_HOME variable, but I'm pretty sure Maven does.


So one can conclude that if any program uses JAVA_HOME, There is two way to avoid above error-
1. If java is insatlled in "Program Files", then kindly put JAVA_HOME value in ""(quotes).
2. Otherwise, java should be installed in such directory, which doesn't have spaces in their name.

Am i right Michael?

Thanks Michael for the response.
Yes you are correct if i will put quotes on Java_Home's value, it will work.

But the same question again, why this is needed in case of running mvn command.
Its not needed when using other commands like javac on command prompt etc.

Thank you Rob for the response.

What you said, is perfect.
But getting this error while running mvn command, not for others like running ant command or
running simple javac command.

What special in the case maven?
Is it kind of bug in maven or something else?

I've not heard of "AbstractDataModel" but perhaps you're referring to "AbstractTableModel".


Thank you for coreting me Pete.

Well, some people say that it would be better, if model class extends AbstractTableModel instead of DefaultTableModel.
Let me tell you my need. I need to fire a query, every ten minutes, to database for table "T",having column of type Date,Integer and String.
Now need to show this data on UI using JTable up to maximum 10 rows.
Now let me know your advice, whether it will good to follow DefaultTableModel or need to extend AbstractTableModel?

Thanks,
Tanzy.

Hi Maneesh,

I tried to implement the JTable. Created my own model by extending "AbstractDataModel" and defined essential method like getValueAt etc. Some methods i want to show :



and to populate data i used this :


And in main method calling in this way :


Now just only one data is being shown in JTable. Where am i doing mistake? Please point it out.

Hi,

How to insert a new row into JTable at every interval of 5 minutes?
Also how to fix the maximum number of rows in the table? Let it be 50 as maximum number of rows are allowed. At the time of 51st row insertion, it should look for the row which was inserted earliest.

Scenario :

There is a table, "mytable" in database, with columns {createdTime, name, address}.
Now i want to display these data on swing UI based on JTable, which gets refreshed at interval of 5 minutes, i.e if there is insertion of any new in "mytable" during the 5 minute interval, then it should insert the same data into JTable.

Thanks.

Thank you Ulf.
I added this to above piece of code


Now the formatting is under control. But still the core problem is not fulfilled, i.e. how to start the x-axis value with one hour back time from the current time. For example if current time is 11:30 PM, the xaxis should start with 10:30 PM.

Thank you Ulf for the reply.
Well i used this for the the demonstration.

In this example, what i saw that x axis value is not fixed. Its getting changed as per value of minute given in data.
For example --

1. Use the sample program with nothing changed.
X axis --> 20:02, 20:04,20:06.......

2. commented these four value --


x axis value --> 21:01:00, 21:01:30, 21:02:00,....

And so on.
I am not getting, how to control these value?

Hi,

The program is creating time chart using

In the program, take the current sysdate. Now chart should start with one hour back date form current sysdate,
And it must be of ten minutes of interval.
How to achieve this?
