Seems you're using a non-default font in your report. You'll need to create an custom font jar file and add it to JasperReports Server's jasperserver-pro/WEB-INF/lib folder. Check the following page for steps on creating custom font jar file
http://community.jaspersoft.com/wiki/custom-font-font-extension

Seems like you're out of memory. Try increasing the jvm memory. Under your tomcatbin, create setenv.bat if it doesn't exist already and add the following to increase memory to 4GB. JasperReports Server needs at least 4GB memory.
set JAVA_OPTS=%JAVA_OPTS% -Xms4g -Xmx4g

That's the specs. Theme can be set per organization whlle the login page is common to all. That's why overrides_custom.css is not used in the login page.

JasperReports Server 6.0.1 doesn't  support JDK1.8. You'll have to use Oracle JDK1.7 or Oracle JDK1.6.

You'll need to send PCL instructions to your printer. Check your printer documentation on how to do this. There's is a direct printing example in the JasperReports library that you may want to look at to get those instructions to the printer.

I'm using JasperReports Server 6.1.0J, which contains bug fixes and added features.

I think you mean Apache httpd server. Unfortunately, you need Java Application container and httpd servers are not application containers. You can front the tomcat with a httpd server so users would have to pass through httpd server.

Select the "Source" tab in Jaspersoft Studio. In line 2, there should be a line like "Create with Jaspersoft Studio version 6.1.0.final using JasperReports Library version 6.1.0"

My bad on this. The report size changes OK when I change actual_size.510.jrxml.

Visualize.js is just a report displaying tool. You can just use the JasperReports Server REST v2 API to schedule a report.
http://community.jaspersoft.com/documentation/tibco-jasperreports-server-web-services-guide/v610/scheduling-report-1

You can add the ?theme=xxx url to regular users logging in - I think this will be easier to do.
Anyways, it's actually a bad idea to use iframe. If you just want to display a report, it's better to use REST v2 API to fetch the report in html format. If you have a commercial version, it's better to use Visualize.js. If you're a community version user, you can try node.js (https://github.com/agmoyano/node-jasper)

You'll need to edit Adhoc View and save it again as Adhoc Report. Adhoc Report does not support report design editing. If should have the original Adhoc

In the Properties View, select "HTML" and expand "Hyperlink". Set Return target to "Blank".

Use Conditional Style.
http://community.jaspersoft.com/wiki/how-apply-conditional-formatting-your-text-fields

Just set the values in Text Field component expression. Text Fields are used to display field values. If you want to use the values else where, use Varialbles instead.

You can just put 4 text fields in 2 columns and 4 rows

Have you checked the following page?

You may also use Custom Visualization component and use something like D3.js
http://community.jaspersoft.com/wiki/creating-your-custom-visualization-components-v60x

This is a bug. I'll just report it in to get it fixed.

I don't think iReport is supported on Ubuntu 15.04. As has been stated several times already, iReport development has stopped last year and is due to be retired at the end of this year. Jaspersoft strongly urges users to use Jaspersoft Studio instead.

Yes. If you're going to upgrade to 5.6.0, better to think about using Jaspersoft Studio because iReport support is going to terminate at the end of this year.

Seems to be working.

I think the sample database is using hsql database. Use something like squirrel sql client.
OR
Just look at my page for the ddl I've converted to use in MySQL database.

Seems to be a problem with sourceforge site.

You should be using compareTo instead of equals
($V{GroupTotalAccrualBasis}.compareTo(new BigDecimal("0.0"))) == 0 ? newBigDecimal("0.0") :($V{GroupTotalAccrualBasis}.multiply($V{bill_payAmount}).divide($V{GroupTotalAccrualBasis}))[/code] 

JasperReports Server stores information necessary to run the server in the database. Such information includes user/password and themes.
As such, you won't be able to setup JasperReports Server without a database.
JasperReports Server officially only supports MySQL, Oracle, PostfreSQL, DB2, and SQL Server as a database to use to store server information.
