# Jaspersoft Studio Installation

Download the Jaspersoft Studio software package. To do that follow the link below and choose an installer suitable for your operating system. http://community.jaspersoft.com/project/jaspersoft-studio/releases

# Report Template. Bands Description

Let us create a report corresponding to the properties page of the started process example.

Jr en1.png

The report will contain general information about the process (definition name, example number, version, when started, status), section of active tasks, swimlanes and variables.

Open the installed Jaspersoft Studio and create a new report.

Jr en2.png

Select “Blank A4” template and press Next.

Jr en3.png

Enter the report name, for instance, “processVariables”, and press Finish.

Jr en4.png

A Jaspersoft Studio workspace will open.

Jr en5.png

The selected “Blank A4” template consists of the following bands:

  • “Title” - report title, displayed only on the first page
  • “Page Header” - section displayed on each page
  • “Column Header” - displayed at the beginning of a report column. We won’t use this band, so left-click it with your mouse and press “Delete”.
  • “Detail” - displayed for each entry in the dataset.
  • “Column Footer” - a band to display data at the end of a report column. We won’t use it, so, delete it.
  • “Page Footer” - a band to display data at the end of each page.

Add two more “Detail” bands to the report. To do that right-click the Detail band and select the option “Add detail band”.

Jr en6.png

Jr en7.png

Save the report (use the Ctrl+s key combination or the corresponding icon on the tools panel).

# Working on the Report Title

As an input value for report formation an Id of a BP example will be used.

Go to the “Parameters” section and create a new parameter.

Jr en8.png

In “Properties” enter the parameter name - “ProcessId”

A BP example Id is an integer value, so set “java.lang.Long” as a class.

Jr en9.png

Go to the element palette and drag “Text field” into the Title band.

Jr en10.png

“Text field” is an element for displaying a dynamically generated string.

# Dataset

Let us display in the title: Process example Id and name of its definition.

To acquire this information you should configure a dataset.

Click the root element “processVariables” on the “Outline” panel, a settings panel will open on the right.

Press “Edit query, filter and sort” .

Jr en11.png

An SQL-query to obtain a process definition name by BP example Id looks like this:

    "BPM_PROCESS"."ID"= $P{ProcessId}

Add this query to the “Texts” window.

Jr en12.png

The query returns a BP definition name. Press “Add” to add a new field. Enter the name – NAME, class type - “java.lang.String”

Jr en13.png

Go to the Parameters tab and define the ProcessId input value type as java.lang.Long.

Jr en14.png

Press OK.

# Expression for the Title

Now we can use the Name field we obtained as a result of the query in the “Text field” element we’ve added to the Title band.

Double click it with your mouse, an expression editor window will open.

In Fields and Parameters the Name field and the ProcessId parameter we’ve added earlier should be present. We can use them in the expression.

Jr en15.png

Enter the following expression:

"Report on the process '"+ $F{NAME} + "' (id=" + $P{ProcessId}.toString() + ")"

To add a field or a parameter into the expression, mark it in the corresponding list and double click it.

To transform the ProcessId parameter (type Long) into a string form, use the toString() method.

Thus, a dynamically generated string, containing the ProcessId and its definition name will be displayed in the report title.

Jr en16.png

Jr en17.png

# Configuration of the Title Display Style

Highlight the title “Text field” and go to the Properties panel. Here you can set an element’s appearance or apply a style.

In the Color section set the text color (Forecolor) and the background color (Backcolor).

Jr en18.png

Use the “DejaVu Sans” font. It allows to display Cyrillic letters correctly in pdf reports.

Set the text alignment and its size.

Jr en19.png

Save the report.

# Band of Detailed Information on the Process Example

In the Detail1 band let us display the id, the name, the start date, the termination date, the version and the status of the process.

# Dataset

To obtain these values you should create a new dataset.

Go to the “Outline” window, open the context menu on the root element and select “Create DataSet”.

Jr en20.png

Give the dataset a name - “ProcessInfo”, create an empty dataset (an empty dataset option).

Go to the ProcessInfo settings and press “Edit query, filter and sort options”.

Add the following SQL query to the “Texts” section to obtain the process information by its Id.


       "BPM_PROCESS"."ID"= $P{ProcessId}

Add the returned fields and set their class types as shown on the screenshot below.

Jr en21.png

# List Element

Let us display the process information by means of a List element.

To do that go to the graphic elements palette, mark List and drag it to the Detail1 band.

You will be offered to select a dataset.

Select ProcessInfo you have created.

Jr en22.png

Jr en23.png

Double click the added List, a form for edition will open.

Place the already known “Static text” and “Text field” elements on the form as shown on the screenshot below.

Jr en24.png

Double click each added “Static text” and enter the names of process parameters.

Jr en25.png

Jr en26.png

Add fields corresponding to the returned fields of the “ProcessInfo” query to the “Text field” elements.

Jr en27.png

Pay attention to phrases like:


In the example above status (EXECUTION_STATUS) verification is carried out, if the value is not assigned (equals NULL), then an empty string will be displayed“”, otherwise it will be status value.

Use such phrases in fields, that may be left unfilled. In this case these are “Status” and “Date of process termination”.

In the ProcessInfo query there is an output parameter “ProcessId”. You should change it into a List element.

Highlight the List, enter its properties, go to the Dataset tab and press Parameters.

Jr en28.png

In the appeared window press Add and select the ProcessId parameter from the list.

For this parameter set an expression like:

Jr en29.png

# Display Style Configuration

Click the Styles element of the “Outline” window and select “Create Style”

Jr en30.png

Create two styles:

1). PropertyName – for elements with names of properties

2). PropertyValue – for elements displaying values of properties

Jr en31.png

Highlight the created style and enter the Properties window.

Set background color, select a font (use DejaVu Sans) and its size.

Jr en32.png

Jr en33.png

Also you can set indents, text alignment, element borders, etc.

Next you should apply the created style to the elements responsible for output of a property’s name and its value in the List.

Mark the element, go to its properties, and on the “Appearance” tab select the corresponding style in a dropdown list.

Jr en34.png

The List element will be displayed as follows:

Jr en35.png

# Active Tasks

Let us display the information on active tasks of the process in the form of a table with columns:

  • State
  • Swimlane
  • Executor
  • Date of creation
  • Date of deadline
  • Actual duration
  • Time until deadline
  • Time to take up for execution

# Dataset

Create a new dataset “ProcessTasks”.

Jr en36.png

Use the following SQL query to obtain data on active tasks:

       FROM (
      "BPM_TASK"."PROCESS_ID"= $P{ProcessId}

Add return fields "TASK_NAME" , "CREATE_DATE", "DEADLINE_DATE", "EXECUTOR_NAME", "SWIMLANE_NAME", "ASSIGNMENT_DATE" and also “ProcessId” parameter.

Jr en37.png

Jr en38.png

As you can see from the query and from the structure of the return fields, kinds of data like actual duration or time until deadline are absent here. These kinds of data are calculated from current time and values of the “Date of creation”, (CREATE_DATE) and “Time until deadline” (DEADLINE_DATE) fields.

“Actual duration” = CREATE_DATE - “Current time”
“Time until deadline = “Current time” - DEADLINE_DATE

Create a new parameter DTNow, which will contain current time.

Use the “java.util.Date” class.

Click the icon opposite to “Default Value Expression” string.

Jr en39.png

Enter the following code:

new Date()

Option “Is For Prompting” shouldn’t be selected because such a parameter can not be used as an input parameter of a query.

Jr en40.png

Besides, to calculate intervals between dates and also to bring dates to a common (displayable in RunaWFE) format, you should use one more parameter – DataFormatter. Its class is ru.runa.wfe.report.ReportFormatter.

To use the ReportFormatter class you should add the following library into the project: File:Wfe-core-4.3.0-SNAPSHOT.jar

Open the project’s properties.

Jr en41.png

Highlight “Java Build Path”, then go to the Libraries tab.

Jr en42.png

Press “Add External JARs” and select a jar file.

Jr en43.png

Jr en44.png

Jr en45.png

Now create a new parameter, name it DataFormatter and give it the ru.runa.wfe.report.ReportFormatter class.

Jr en46.png

Set the default value expression in the form of the following string:

new ru.runa.wfe.report.ReportFormatterImpl()

Return to the ProcessTasks dataset, open the parameters tab, add DTNow and DataFormatter.

Jr en47.png

# “Active Tasks” Table

From the graphic elements palette add a table (Table element)

Jr en48.png

Use the “ProcessTasks” dataset you have created.

Jr en49.png

Double click the table to edit it.

Jr en50.png

Highlight and delete “Column Footer” and “Table Footer” one after another.

Jr en51.png

Create 8 columns

Jr en52.png

Group the columns in the heading and expand the acquired table over the whole area.

Jr en53.png

Position the “Static text” elements and enter the columns’ names.

Jr en54.png

In the value columns position the “Text Field” elements.

Jr en55.png

Use the following expressions for the fields:

  • State
  • Swimlane
  • Executor
  • Date of creation
  • Date of deadline
  • Actual duration
  • Time until deadline
  • Assignment date

Jr en56.png

For Timestamp format fields the Data Formatter is used. It allows to convert the value into a display format common with RunaWFE. By means of interval method (StartDate, EndDate) an interval between the two specified dates is calculated.

The DTNow, DataFormatter and ProcessId parameters should be sent to the dataset of the "Active tasks" table.

Jr en57.png

# Table Styles

Along with a table styles are created automatically.

Jr en58.png

Edit them and apply to the title, cells with names of parameters, value cells.

Jr en59.png

# Swimlanes Information Section

Create a new dataset “processExecutors”.

To obtain the swimlanes of a BP example use the following SQL query:

       "BPM_SWIMLANE"."PROCESS_ID"= $P{ProcessId}

Jr en60.png

In the Detail2 band position the table to display swimlanes of the BP example, use processExecutors as a dataset.

Add the following expressions for the Swimlane and Executor fields:


Apply styles to the table.

Jr en61.png

# Table of Process Variables

Create a new dataset to obtain values of variables of the BP example.

        PROCESS_ID= $P{ProcessId}

Jr en62.png

Create a table to display values of variables of the BP example in a similar way to the swimlanes table and position it in the Detail3 band.

Jr en63.png

Use the following expressions for the "Variable Name" and "Value" fields:


# Page Footer Band

In the footer of the report position two “Text Field” elements with expressions like:

"Page " + $V{PAGE_NUMBER}
" of " + $V{PAGE_COUNT}


  • PAGE_NUMBER – number of the current page
  • PAGE_COUNT – number of pages in the report

Jr en64.png

# Report Compilation

Select the report file (.jrxml extension), open the context menu and select “Compile Report”

Jr en65.png

If there are no errors in the report, a file with .jasper extension will be generated. You will be able to upload it to RunaWFE server.

# Report Deployment and Execution

Open “Reports” and press Deploy.

Select a report file (.jasper extension) and fill in the required fields.

Press “Analyse”.

Jr en66.png

Enter visible to user name for the ProcessId parameter.

Jr en67.png

Select the Integer type, set the parameter as required.

Press “Deploy”, the report will appear in the list.

Jr en68.png

Execute the report:

Jr en69.png

Enter the id of the BP example you want to obtain the data on in the report and select the report type.

Press “Build”.

Below you can see the examples of built reports.
