[jasperreports-questions] Defining one style for different fields, how should the constraint look like?

[psentosa <psentosa@ya...>]

Hi all,

I just started using JR for an application, and I'd like to define one style
for different fields, that contains constraints.
As far as I know, I have to write down the field name as part of the
constraint; 
e.g new Boolean($F{h4p1}.equals("I"))  --> than use background colour green

but that means, if I'd like to use the same style for all fields, I have to
create style for each field, with constraints that vary basically only in
the name of field using as constraint, and I have a lot of this fields
Is it possible to use kind of wildcards in the constraint?

Many thanks in advance for any help

[jasperreports-questions] The last entry in The PDF format is not getting dispalyed properly.

[jasper_Q <siddarthaprasad@gm...>]

In my Jasper Report I have the cloumn property set at stretch key and I am
dispalying some key value in that.

The problem I am facing is the last entry in the coloumn in an page
overflows to the next page evn though there is space in the current page for
the value to be dispalyed.

eg.. This value   1234566789900 

for other entries in the page it is getting  displayed as 1234566789900 
for the last entry in the page is getting displayed as 12345667899  
.......Current page
                                                                       00                
....... Next page

Re: [jasperreports-questions] Custom xml Creation ??

[jasper_newbie <mails2tpillai@gm...>]

Hi,

Did you try the option of using "XML DataSource" via IReport ?
I think you would need to use "XML DataSource".
Need to use XPath to identify your dataset ie XPath expression for the nodes
selection.
The XPath specifics are available at the web page
http://www.w3.org/TR/xpath.

I'm sending you a part of my code:

my web.xml contains:
 <servlet>
                <servlet-name>ImageServlet</servlet-name>
                <servlet-class>
                        net.sf.jasperreports.j2ee.servlets.ImageServlet
                </servlet-class>
        </servlet>
<servlet-mapping>
                <servlet-name>ImageServlet</servlet-name>
                <url-pattern>/reportImage</url-pattern>
        </servlet-mapping>
-----------------------------------
and my code is as following:
JasperReport jasperReport = getCompiledReport(reportPath);
                        JasperPrint jPrint =
JasperFillManager.fillReport(jasperReport, getGraphParameters(), ds);
                        request.getSession()

.setAttribute(ImageServlet.DEFAULT_JASPER_PRINT_SESSION_ATTRIBUTE, jPrint);
                        ByteArrayOutputStream out = new
ByteArrayOutputStream();
                        String imgExtension =
String.valueOf(randomImageExtensionGenerator.nextInt());
                        exporter = new JRHtmlExporter();

exporter.setParameter(JRExporterParameter.JASPER_PRINT, jPrint);

exporter.setParameter(JRExporterParameter.OUTPUT_STREAM, out);

exporter.setParameter(JRHtmlExporterParameter.IMAGES_URI,
request.getContextPath()
                                        + "/reportImage?rnd=" + imgExtension
+ "&image=");
                        exporter.exportReport();

i add random parameters to the end of the image path in order to renew the
browser cache for every request.
I hope this helps.

Regards

[jasperreports-questions] HEP: I don't see the image!!

[Esaú Castillo Contreras <esaucastilloc@gm...>]

Hi!!

I generated a file jrxml using the iReport 3.0.0 and when I try to print the
report in a servlet the html doesn't show the images of a 3D Chart,

This is the code in my servlet

         JasperReport jasperReport =
JasperCompileManager.compileReport(jrxmlPath);
         JasperPrint jasperPrint =
JasperFillManager.fillReport(jasperReport, parameters, getConnection());
         JRHtmlExporter exporter = new JRHtmlExporter();

request.getSession().setAttribute(ImageServlet.DEFAULT_JASPER_PRINT_SESSION_ATTRIBUTE,
jasperPrint);
         exporter.setParameter(JRExporterParameter.JASPER_PRINT,
jasperPrint);
         exporter.setParameter(JRExporterParameter.OUTPUT_WRITER, out);

exporter.setParameter(JRHtmlExporterParameter.IS_OUTPUT_IMAGES_TO_DIR,Boolean.FALSE);
         exporter.exportReport();


My project uses the library 3.1.3

Thanks
