Integration between alfresco and java application

I have a Java Application and I need to get a Jasper report located in Alfresco. Once I have the report I need to add some parameters and then compile it and generate a PDF.
I know this is possible, using alfresco API and Jasper Report API. I have searched in Java-backed Web Scripts Samples but I don't understand the examples, because i'm new in Alfresco and Java, so any clue would be appreciated.

You might be interested in Benjamin Rodriguez' Jasper Reports Dashlet which he submitted as part of last year's Dashlet Challenge. The dashlet makes it possible to configure and run Jasper reports from within the Share UI. This isn't exactly what you are trying to do but it may be a good source of example code.

Java library which can generate charts from sql

I have weblogic where I can deploy this java application and database where I have data. Can you recommend me some free java library which can generate charts from my data ?
I found http://oreports.com/ but their forum seems to be inactive for a long time so when I want to advice I have problem

Try out Jasper Reports.

List of open source options for generating reports in java.
I personally recommend JasperReports.

I found this: http://art.sourceforge.net/ which is exactly what I need

Assuming nothing like presenting charts from data directly without any java app. (So no informatica like tools) jfreechart is an option. have a lookt at fusion-charts too

How can I generate reports containing charts with Pentaho and Java?

We have a Java EE based web application and we want to integrate Pentaho reporting API into this application.
So, I'm trying to learn how Pentaho can automatically generate reports containing charts. I have downloaded Pentaho BI server and played with it for a few days. But I'm still clueless about the following issues:
How to generate reports dynamically at runtime without loading those *.prpt files.
Where I can get a simple tutorial about dynamic report generation
What the difference is between Community Dashboard Framework, charting tools and reporting tools.
The documentation on the Community Dashboard Framework site is not properly organized, and there is not a single tutorial about getting started.
If anyone can help me find the answers to some of my questions, it will be great!

You can define reports purely via the API of the reporting engine. Samrat is right on that the preferred way of defining reports is the report designer - as code changes are harder to maintain than changes of a GUI-editable external report definition.
I think the best way to go forward is to grab Will Gorman's book about "Pentaho Reporting 3.5 for Java Developers" which gives you a deep insight into the inner workings of the reporting engine and also how to define reports dynamically.
CDF vs Reporting: CDF is a javascript toolkit for creating interactive dashboards. Dashboards are aimed to provide a high-level overview over the state of your company with the ability to drill down or even customize them. Reports produced by the reporting engine are predefined/"canned" reports that we expect to be run frequently to answer specific business questions. Charts components are just components that produce a given chart for dashboards based on a set of input parameters.
CDF uses reports and charts as content in dashboards.

Without prpt files there is no pentaho reporting. To achieve dynamically, run the pentaho BI server and pass the parameters to the report. Load the report in iframe.

Alternative to subreports in JasperReports

I am using JasperReports in my project. During the generation of reports, I am forced to retrieve data from different tables in the database. I have used subreports, but this solution is not satisfactory for me. Main reason for this is fact that for each report I have to prepare two jrxml files. For the assumptions of my project this is not effective.
Is there an alternative to subreports? If it is important I use Hibernate.

Mateusz, you can prepare data source manually in java code and pass is to the report.
Sometimes the good subreport's alternative is using group(s) in report.

At a higher level what are you trying to achieve ?
If the reason you're using subreports is to embed mulitple graphs/chart widgets that display different but related data, then an alternative way to doing this is using subdatasets
Innformation on using subdatasets can be found in iReport Ultimate Guide, but basically they are extra sub queries you can run in addition to the main report query, whose results can be access by Charts/Charts Pro widgets (see the chart data tab in these widget properties)

Best way of printing simple reports in java

I have developed a Java application and now i want to give some simple printing support. Something like printing invoices , some reports etc.
Right now I'm creating that stuff in html, showing it on JEditorPane. but html support is quite poor and I'm really fade up of that thing. Is there any better way of doing such thing?
Any better browser component, or better tool to create such simple reports? (JDK 1.6)

I love JasperReports for that. In combination with iReport (a GUI for creating the reports) is the best I could find for free in Java to do reporting.
You can also generate PDFs files with iText for printing. Although I think it will be easier to use iReports.

JasperReports is a pretty nice reporting tool for Java. It could be a bit heavy weight for what you want.

Another solution is BIRT which is very simple to use : it is an Eclipse project with a visual editor for your reports. The report is built in 3 steps :
create a DataSource
create a DataSet on this DataSource
create your report, based on the DataSet

DynamicReports is an open source reporting tool. You can create reports quickly without needing to use a visual designer. See the examples.

When printing invoices and reports, no doubt you want them to look more than basic - hence your problem. If your swing application has a server-side component, then look at libraries like Jasper and Docmosis to produce decent reports from the server (since heavy-weight server side is typically aok). If you really need a library just for a client app, there's an old library called JViewPro which is pretty yuk to code with, but can let you layout reports in code for displaying and printing and is a single jar (just be careful about memory usage).
