This seems to suggest there's a problem with connecting to your postgresql from JasperReports Server. Have you tried testing the data source from JasperReports Server to make sure the connection is good. In the Data Source page, select "Test Connection".

If you are looking on using community version, your option is to use Jaspersoft Studio to design reports and to upload the design file to JasperReports Server to view the report on the web.
If you have looking on using the commercial version, JasperReports Server offers a tool to design simple reports from web browsers.
Both options have permission features.
Whether to let customers design and upload reports or not depends on your policy rather than on feature of the software.

If you really mean Jaspersoft Studio, the no.
If you are generating a report from JasperReports Server, then it is possible to display the logged in user name of the person generating the report.

Go through Jaspersoft Studio documentation on how to create reports with JasperReports.

What are you doing with while(rs.next())?
Instead of trying to read result set in your program, your jrxml should have "name" and "yourad" fields (not parameters but fields).
Delete the following lines.
while(rs.next()) { parameters.put("name",rs.getString("name")); parameters.put("youad",rs.getString("youad"));[/code] 
 

Jaspersoft Studio comes in 2 versions; commercial and community. Commercial version is under a proprietary license but the community version is under EPL. There's some other projects bundling and distributing the community version already.

No unless you create different reports from the beginning.

Including html page with jquery scripts in JasperReports is not possible.

It's because HTML skips all leading spaces. Instead of uisng Idents use Borders - Padding

Jaspersoft Studio defaults to using the last parameter values. To get the Input Parameter prompt back, click on the show input parameter icon at the top right corner.

Finished customizing JasperReports library to support PostScript exporter.

Just place Text Fields for each fields into the Detail band as you want them (with 3 rows). Just want "Item-Item Long Description" and "Inco Term Location" fields to span several columns in the first row.
Then, place borders on each field.

Not by default. I had the same requirement because I needed to print out to a postscript printer.

JasperReports is using commons-digester v2.1 instead of version 3
<dependency org="commons-digester" name="commons-digester" rev="2.1"/>

https://stackoverflow.com/questions/12688778/increase-tomcat-memory-settingsJasperReports only output 1 pdf per report. You'll have to create your own program that uses JasperReports library to do that.
I've done what you've asked before several times so I'm definitely sure that it's possible if you build your own program.

Instead of moving the bands for the first page, set the content of the title band to have the content of the page header.
Title band is only printed once.

Check that the subreport isn't placed in the detail band.

I think that's against the license so NO.

There's some .properties files under webappsjasperserverWEB-INFbundles
Just copy files without the language (e.g. AttributeBundle.properties) and change the file name to end with "_fi.txt".
You'll need to translate text after "=" in each row
You'll then need to convert the text file you just translated to use unicode escape sequence.
Check the following documentation:
https://community.jaspersoft.com/documentation/tibco-jasperreports-server-administrator-guide/v60/localization

Try setting the following property to "false" in your report.
net.sf.jasperreports.export.xls.collapse.row.span
 

I think Highcharts is only available in commercial versions of JasperReports. Check if you are using commercial versions of both Jaspersoft Studio. Note that Jaspersoft Studio will automatically switch to disable commercial features if license is not entered within 30 days after installation.

Take a look at this question. You need to export your custom function as jar file and uploading the jar file to JasperReports Server.

Don't know what the problem is. Can't you just create a method to generate csv file and call it twice in 1 submit action?

Jasperserver 3.5.1 is too old. Try versioning it up to at least 6.2.x
