Dynamically show or hide table in jasper report

Question

I am facing problem to show or hide the table in Jasper Report.

When no data are available then it's show a horizontal line.

I want to hide the static text field and table from report when the query retrieves no data.

Can anyone help me?

Here I have attached my output.

You could try setting a Print When expression for the static text and also for each column of the table.

Here's an example of how it could look:

// determine somewhere whether the received table data is empty or not.
// save the result as a boolean and add it to report parameters
boolean ifTableEmpty = false;  // for example
parameters.put("ifTableEmpty", ifTableEmpty);

// create a Print When expression
JRDesignExpression whenToPrintTheTable = new JRDesignExpression();
whenToPrintTheTable.setText("$P{ifTableEmpty}");    

// add the expression to your static text and similarly for each column
staticText.setPrintWhenExpression(whenToPrintTheTable);
