Yes. There are several ways.
First is to use use Text Field and have if conidtion to choose what to display.
e.g.
$P{Parameter1}.equals("a")?"all":$P{Parameter1}.equals("f")?"few":"None"[/code]Second is just to create layered Static Text components and use Print When Expression to choose which Static Text to display.
Third is to use scriplet to replace the value. If there are many reports requiring the same substitution, this may be the easiest to maintain.

JasperReports and Jaspersoft Studio just specifies the report layout. How it is viewed is controlled by the application such as JasperReports Server or other applications using JasperReports to display reports.
Unfortunately, JasperReports Server does not have a feature to auto-refresh reports. However, it is possible to schedule a report so it would generate a report periodically. ("Recurring" in the following page)
https://community.jaspersoft.com/documentation/tibco-jasperreports-server-user-guide/v71/creating-schedule
 

You probably have to upgrade to JasperReports Server 7.1.x because JasperReports aren't 100% compatible between versions so it probably isn't about just replacing the jar file.
https://community.jaspersoft.com/documentation/tibco-jasperreports-server-community-project-upgrade-guide/v640/upgrading-63-64

Try
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { String parameter = request.getParameter("BOOKING_ID"); JasperPrint jasPrint = null; try { jasPrint = generateJasperReprotPrint(); System.out.println("jasPrint +jasPrint" + jasPrint); String file = "TEST.pdf"; ServletOutputStream sos = response.getOutputStream(); response.setContentType("application/pdf"); JasperExportManager.exportReportToPdfStream(jasPrint, sos); -- I am getting exception here in dev server but in local server it is working fine . } catch (JRException e | SQLException e) { System.out.println(e.getMessage()); e.printStackTrace(); } }[/code] 

There is a following line in build.xml file. Since target and source still points to "1.8", it implies 1.8 is still supported. In fact, when I'm creating pull requests on JasperReports, I'm using 1.8  because of this.
<javac destdir="./build/classes" debug="true" optimize="false" target="1.8" source="1.8"

1. Download the TIB_js-jrs-cp_7.1.1_bin.zip file.
https://sourceforge.net/projects/jasperserver/files/JasperServer/JasperReports%20Server%20Community%20Edition%207.1.1/TIB_js-jrs-cp_7.1.1_bin.zip/download
2. Extract the file.
3. There is a "samples" directory. Move to this directory.
4. There is a "externalAuth-sample-config" directory. Move to this directory.

Yes. Further info on itext licensing.
https://community.jaspersoft.com/wiki/issue-concerning-itext-licensing-tibco-jaspersoft
Jaspersoft in earlier 6.x version had a license agreement with iText to bundle itext 5.x, but it ended when Jaspersoft were bought out. So they reverted back to itext 2.1.7 based customized version. iText changed some package and class names in 5.x when they became corporate.

Instead of setting Stretch with Overflow, set the following property in the text field to "true"
net.sf.jasperreports.print.keep.full.text 
 
Select the text field. Select "Advanced" tab in the Properties. Expand "Misc" and select "[Properties: 0]" Search for the above property and set it to "true"

Was able to display the chart after following changes.
Changed the data as below:
{"Data": [ { "x":1, "y":2 }, { "x":2, "y":3 } ]}[/code]And moved the chart to ehe Summary band and deleted all other bands to make it clearer.

Unfortunately no. However, it's possible to write servlets that uses JasperReports Server's REST APIs to integrate systems.
https://community.jaspersoft.com/documentation/tibco-jasperreports-server-rest-api-reference/v710/rest-api-overview

This is resolved in jasperreports-6.8.0

This is resolved in jasperreports v6.8.0

Not sure what you're trying to do. Are you trying to exclude *.jasper files from the java build path?
If you just want to hide *.jasper file from showing on in Project Explorer, just click on the down-ward pointing triangle icon in the Project Explorer's top right side and select "Filter and Customization" and then check "*.jasper compiled reports".
 

>Also, when I created the third report in detail band, the report was shown 13 times(My report had 13 rows). How can I solve that problem?
Move it to the title or a summary band.

You'll need to break it up into separate fields
OR
make your text include the '<a href=' and then set Markup to 'html'
<textField> <reportElement x="400" y="0" width="100" height="30" uuid="24d2d9fb-41ea-44b1-bece-83c0eeb97f91"/> <textElement markup="html"/> <textFieldExpression><![CDATA["Text <a href=http://www.google.com'>Field</a&gt]]></textFieldExpression> </textField>[/code] 

>de.cimt.talendcomp.jasperscheduler.ReportStarter
This is a component in Talend Open Studio developed by Talend community user. It's still using SOAP instead of REST API.
Just seems like the component hasn't been updated for the new versions of JasperReports Server.

Assigning privlleges to a report per user or using a role should prevent user from accessing a report.
https://community.jaspersoft.com/documentation/tibco-jasperreports-server-community-project-administrator-guide/v71/managing-roles
 

Dynamically updating subreports is not supported by JasperReports. You'll probably have to create different reports and link them by hyperlinks.

Use regular text field instead of static text component. *static* means you can't change it with value from a database.
Also, Print When Expression is used to put an expression that is used to determine whether to display the text or not.
What you want to do is use a regular text component and put your expression in the regular expression field.

Have you tried changing the "Layout" to be "Horizontal"?
https://community.jaspersoft.com/wiki/jaspersoft-studio-layouts

Have you tried suggestion in the following page?
https://community.jaspersoft.com/wiki/unusual-error-no-row-given-identifier-exists

Domain is only available in commercial version of JasperReports Server. If you are using the community version, there's no Domain and Adhoc Reports.

Just tried it and the text is centered even in pdf.
Select the text filed, select "Properties" tab and select center icon in the "Text Alignment".

Shouldn't edit the generated zip file directly. Change the jasperreports server and generate the zip file.
Instructions are provided in the following page.

Yes. You can use Jaspersoft Studio to design your reports and use JasperReports Server to view reports from web browser.
