How to display one group per page using Jasper Reports? - jasper-reports

I'm using iReport to create a Jasper Report template, and I need to display one group per page:
Group 1: (Page One)
-Field1 Field2 Field3
Group 2: (Page Two)
-Field1 Field2 Field3
And so on.
I tried setting the Maximize Band Height property to true in the "Group Footer" band using iReport, but some empty pages are added when I try to review.

You can use isStartNewPage attribute of group.
You can add Group Header band and
1) set "Start on a new page" attribute as true
2) set band height as 0 (if you don't need it).

Why does only my first subreport display?

When I switch sub reports the first of them displays correctly, and the other one disappears. In JasperSoft Studio everything is fine, the problem starts when I export them to pdf/xls.
Actually, only one of them (the first) is displayed.. When I switch sub reports the first of them displays correctly, and the other one disappears
You are declaring:
<parameter name="DS1" class="net.sf.jasperreports.engine.data.JsonDataSource"/>
<parameter name="DS2" class="net.sf.jasperreports.engine.data.JsonDataSource"/>
The JRDatasource is consumable, which means that if you use it to fill one report it will be consumed hence for next report calling next() on same datasource will return false.
What you are experiencing is what happens if you pass same (same Object) datasource for DS1 and DS2, DS1 will be consumed filling first subreport and then since DS1 == DS2 DS2 will already be consumed when filling second subreport, second report will have no records (empty).
Solution
You need to make a clone DS1, create a new Object and pass that as DS2. The JsonDataSource is theoretically also a JRRewindableDataSource, so you could call moveFirst() before filling second subreport, but this is not very easy from the jrxml file so I don't suggest trying to use this method.

Sum columns based on custom group (Jasper Reports) [duplicate]

First of all, the records are shown in the table by table component but not in the report one.
The results looks like this:

The sumquarter column shows the sum of each quarter in year.
They are not printed when it repeated the value of the field.
The question is how to group the column of sumquarter, so that the first printed repeated value in each row to join the next repeated value to become a single cell until it meets the non-repeated value?
You can simply see it in an image.
Below is the image that the table shows and the solution that I preferred is to group those 3 months of sum into a single cell.
Here is the image:

The result will be (in pdf format):
In this sample I've used two elements in the Detail band for the Year column:
one textField with only vertical borders and with printWhenExpression: "$V{yearGroup_COUNT} == 1" property (I'm show it only once for the whole yearGroup) and one staticText without any text and with only vertical borders.
I've used three elements in the Detail band for the Quarter Sum column:
one textField with only vertical borders and with printWhenExpression: "$V{quaterGroup_COUNT} == 1" property (I'm show it only once for the whole quaterGroup), one staticText without any text and with only vertical borders and the line element for drawing horizontal border with printWhenExpression: "$V{quaterGroup_COUNT} == 1" property.

Table with additional record repeating for each row with condition if and only if additional detail does not null

My problem is much similar like as iReport table with additional record repeating for each row
But there should be condition in printing that if and only if additional detail does not null.
If additional detail were null then start printing the next row in the place of otherdetails.
In below photo row0 have no any details so "Detail about row0" is not print and next row "row1" take place.

How to avoid using a lots of ternary operators for translation of value to text

I am using JasperReports to create some reports of a Django web application.
Let's say that I have a model that has an id and a value. This value is a Django choice so I end up in my database with only the keys and not the values (the values are in my code). To make it more clear for people that don't use Django, I end up with something like that in my database:
id value
1 'GD'
2 'VG'
3 'VG'
4 'VG'
5 'GD'
6 'AV'
7 'GD'
8 'AV'
I want to display Good instead of 'GD', Average instead of 'AV' and Very Good instead of VG in my report. I know that this can be done with two equally not desirable to me options:
Create a new table in my database that has key - value and join that in the JR query. I really hate this because I'd need to create around 10 such tables.
Use the ternary operator to display the correct value:
field.equals("GD")?"Good":(field.equals("AV")?"Average":(field.equals("VG")?"Very good":"-"))
I also hate this because it would be very complicated if I had, for instance, 10 key-value pairs.
My ideal solution would be to define a dictionary (HashMap) variable in my report that would contain all the key value pairs and then just do a DICTIONARY.get(field) to represent the field value. Can this be done ? Can you possibly propose another, better solution?
Please don't tell me to alter my database design, I know that some people won't like but it perfect for my needs.
You can solve this issue with help of Java. For example, the Guava library can help us in solving this task.
Using report's parameter
We can add the parameter of java.util.Map type and use it for extracting the value by the key (it can be the value field from your sample)

In this sample we use ImmutableMap.Builder class for creating and filling the Map.
The result will be (via iReport preview):
As you can see that the third columns contains null value for values that are not in Map.
Note: Don't forget to add Guava library to classpath.
Using scriptlet
You can do the same with help of Scriptlets.
You can write the simple Java class with static method, for example for getting value from the Map.
Using internationalization mechanism
May be the simplest way is to use report's internationalization support.
You can attach the properties file with values to your report.

Conditional Horizontal line in jasperreport between results

I'm using jasperreport 4.7.0
I have a query where I order by name then date .
Now the clients wants that when the name changes that we add an horizontal line (see attached img - red line)
Is there a way to accomplish this without duplicating the query and the fields ?
Result :
For solving your task you can use Data Grouping.
The possible steps (there are a lot of way to reach your target) for adding line are:
Create the report Group (via context menu Add Report Group in iReport) on field
Add Group Footer Band
Add Rectangle element to the Group Footer Band
Set Height, Forecolor and Backcolor for this Rectangle - drawing "red pencil line"
