Hi

We applied this fix to our local version of Jasper Server Community Edition:
(It corrects the naming issue and also allows direct opening or saving of the pdf rather than opening in a browser window.

In ReportPdfExporter.java, setAdditionalResponseHeaders()

remove:

response.setHeader("Content-Disposition", "inline; filename=\"" + getFilename(context, "pdf") + "\"");

replace with:

// allow the download dialog box to open:
response.setHeader("Content-Disposition", "attachment; filename=\"" + getFilename(context, "pdf") + "\"");

// fix for opening PDF in IE6:
response.setHeader("Cache-Control", "must-revalidate, post-check=0, pre-check=0");

In view-report.js, exportReport()

comment out or remove these lines so that a blank html window doesn't open:

setBlankFormTarget();
setTimeout('setSelfFormTarget()', 500);

I noticed that grouping is missing in netbeans:

1. in classic, you can select items that you want to group, right click and then select 'Group selected element(s)'

2. if you add elementGroup tags in the code and then go to Report Inspector, the label 'Element group' is missing next to document structure item

Hi Sherman,

I have 2 reports on JasperServer (Community edition) which both use the same query - one is a summary report and it has drill down 'report execution' hyperlinks to the other report which is a detail report. The detail report also has links back to the summary report.

Rather than execute the query everytime a link is clicked (which effectively loads/re-loads the linked report), is there any way that I can pass the cached query results from one report to the other? Perhaps via a report scriptlet?

Regards,

Richard

Thanks Lucian!

The custom classloader works fine.

Hi,

I am trying to compile a report using JasperCompileManager.compileReport(...). As I use my own classes I have to set the classpath using: JRProperties.setProperty(JRProperties.COMPILER_CLASSPATH, "..."). This seems to work ok as long as I have the classes in the WEB-INF/lib directory. However, if I have a class outside of WEB-INF/lib and add it to the classpath using JRProperties.setProperty(JRProperties.COMPILER_CLASSPATH, "..."), I get the following exception:

net.sf.jasperreports.engine.design.JRValidationException: Report design not valid :
1. java.lang.ClassNotFoundException: com.verticali.vap.reporting.scriptlets.ReportScriptletUtils
at net.sf.jasperreports.engine.design.JRAbstractCompiler.verifyDesign(JRAbstractCompiler.java:260)

at net.sf.jasperreports.engine.JasperCompileManager.compileReport(JasperCompileManager.java:220)
at net.sf.jasperreports.engine.JasperCompileManager.compileReport(JasperCompileManager.java:206)

This looks like the same bug as reported in:

http://jasperforge.org/plugins/espforum/view.php?group_id=102&forumid=103&topicid=18750

In that bug, Andrey Shuvikov wrote: "Looking in the code I noticed that JRAbstractCompiler calls verifyDesign() _before_ dealing with classpath. But JRVerifier tries to load classes to verify their type, and classpath is not yet set at this point. Is it a bug or did I misunderstood the code?"

There is mention of a patch in that bug and I also found a related patch: http://jasperforge.org/tracker/index.php?func=detail&aid=246&group_id=102&atid=369&action=edit

I tried using the latest version of jasper reports: jasperreports-3.0.0-javaflow.jar, but this did not fix the problem.

Is there a patch available to fix this?

Hi Teodor,

Can you please let me know where the formulas are being stored for iReport 2.0.2?

Hi,

I noticed that the file expressions.xml, which used to contain the formulas used in iReport is no longer in the user home > .ireport directory for iReport 2.0.2.

I would like to modify the file with methods that I have in the Report Scriptlet class so that they can become available to use in iReport.

Can you please let me know where the formulas are now being stored?

Hi,

This is a duplicate of a previous entry:

see

http://www.jasperforge.org/index.php?option=com_joomlaboard&Itemid=&func=view&catid=8&id=28509#28509)

Basically, the rows in Excel don't stretch enough to display all of the text in cells when exporting reports to Excel. It works ok when there is no text overflow, but when there is text overflow, only a proportion of the text is visible in excel.

Is there a way to add Excel macro detail in a report template to get the spreadsheet to auto-fit the text?

Currently users need to manually auto fit text in Excel by: selecting the rows in excel and then from the menu: Format->Row->AutoFit. However, using this can cause the page height to extend beyond the printable height for the page.

Regards,

Richard

Hi,

Is there anyway to do the following:

(1) Styles

Is it possible to have a single styles file which would be included included in the main report and all associated subreports?

This would be very useful as I have a complex report with several subreports and have had to copy and paste the styles into every template.

(2) Includes

Is it possible to include sections of code into the templates? I have several subreports which have similar code and only differ by filter expression, heading text and color, so again this would be very useful here.

Please let me know if any of the above are possible or are in the pipeline.

Hi,

I would like to have some text rotated at 90 degrees. This works fine when I output to PDF but doesn't work at all when outputting to WORD.

Is this likely to be fixed soon?

August 20, 2007

Hi,

I have a main report consisting of dynamic text fields which are required to stretch when the data overflows. This works fine for fields which belong to the main report. However, I also have variables which are returned from a subreport to the main report - when I display these as dynamic text fields, they do not stretch.

Is this because the stretch positioning is determined before any subreport values are returned? If yes, is there any way to make the stretching be evaluated later, i.e. after the values have been returned from the subreport?

See:

http://www.jasperforge.org/index.php?option=com_joomlaboard&Itemid=215&func=view&catid=9&id=28789#28789

It's possible to add a list of methods to the file expressions.xml in:

userhome > .ireport

These methods are then available in the formulas list.

Ok, so no replies to this post so far, but in the meantime I have discovered that there is a file in userhome >.ireport called expressions.xml.

I can add all of my ReportScriptlet methods to the expressions.xml file and then they become available in the formulas list when using iReport.

Note: you need to restart iReport after updating expressions.xml

Hi,

I would like to import a text file containing a list of methods into the formulas list of iReport.

However, when I import several methods, they are all listed on a single line in the formulas window.

How can I add a new line character to separate each method?

For more detail:

I have a text file called ReportScriptletMethods.txt which contains methods such as:

$P{REPORT_SCRIPTLET}.getCurrentYear()

$P{REPORT_SCRIPTLET}.getCurrentMonth()

$P{REPORT_SCRIPTLET}.getCurrentDay()

I go to: Options > Formulas, click the 'New' Button, and then click the 'Import' Button and then navigate to my file 'ReportScriptletMethods.txt' file and then click 'Apply' and save.

However, all of the methods are saved to a single line in the formulas window.

Then, if I work on a variable expression and open the formulas window and select one of the imported methods, the entire list of imported methods gets selected.

Is there a special new line character that I can use to separate the methods in my import list?

Thank you.

Cheers,

Richard

Hi,

I would like to view custom methods from my ReportScriptlet class from within iReport - Is it possible to load in the methods so that they can be seen and selected from the User Interface?

If it is possible, please describe the steps involved.

Thank you,

Hi Teodor,

Here's more detail and findings.

From some searching on google:

Most browsers can't print partially transparent PNG images. (ref: http://www.econym.demon.co.uk/googlemaps/custom.htm)

Firefox 1,0 won't print any PNG files that have transparency (ref: http://groups.google.com/group/Google-Maps-API/browse_thread/thread/c06c9736455921b3)

Need to find out if either of the following are possible:

(1) how to render the entire chart - particularly the surrounding chart axis areas without any transparent regions at all

or

(2) how to render the chart as a gif instead of png in Firefox

I am using Firefox version 1.5.0.11

Here is more complete code that I am using:

Code:

public abstract class Chart
{
    protected JasperDesign design = null;
    protected JRDesignBand band = null;
    protected JRChartDataset dataset = null;
    protected JRDesignChart chart = null;
    private int pageHeight = 577;
    private int pageWidth = 630;
    private int chartHeight = pageHeight;

    public Chart(byte chartType, boolean small)
        throws JRException
    {
        if(small) {
            pageHeight = 385;
            pageWidth = 420;
            chartHeight = pageHeight;
        }

        design = new JasperDesign();
        design.setName("DataSourceReport");
        design.setLanguage("java");
        design.setPageWidth(pageWidth);
        design.setPageHeight(pageHeight);
        design.setColumnWidth(pageWidth);
        design.setLeftMargin(0);
        design.setRightMargin(0);
        design.setBottomMargin(0);
        design.setTopMargin(0);

        JRDesignField name = new JRDesignField();
        name.setName("OID");
        name.setValueClass(String.class);
        design.addField(name);

        band = new JRDesignBand();
        band.setHeight(pageHeight);
        design.setTitle(band);

        chart = new JRDesignChart(null, chartType);
        chart.setEvaluationTime(JRExpression.EVALUATION_TIME_REPORT);
        chart.setPositionType(JRDesignChart.POSITION_TYPE_FIX_RELATIVE_TO_TOP);
        chart.setX(0);
        chart.setY(0);
        chart.setWidth(pageWidth);
        chart.setHeight(chartHeight);
        chart.setBorder(JRGraphicElement.PEN_THIN);
        chart.setBorderColor(Color.BLACK);
        chart.setBackcolor(Color.WHITE);
        chart.setForecolor(Color.BLACK);

        chart.getPlot().setLabelRotation(30);

        chart.getPlot().setBackcolor(Color.WHITE);
        chart.getPlot().setBackgroundAlpha(1.0f);
        chart.setShowLegend(!small);

        band.addElement(chart);
    }

    public void add(Object o)
        throws JRException
    {
        if(JRDesignVariable.class.isInstance(o)) {
            design.addVariable((JRDesignVariable)o);
        } else if(JRDesignGroup.class.isInstance(o)) {
            design.addGroup((JRDesignGroup)o);
        } else if(JRDesignField.class.isInstance(o)) {
            design.addField((JRDesignField)o);
        } else {
            throw new JRException("This type of object is not supported with this method.");
        }
    }

    public void compile(ByteArrayOutputStream stream)
        throws JRException
    {
        JRProperties.setProperty(JRProperties.COMPILER_CLASSPATH, "lib/core/jasperreports-1.3.0.jar");
        JasperCompileManager.compileReportToStream(design, stream);
    }

    public String getXML()
        throws JRException
    {
        JRProperties.setProperty(JRProperties.COMPILER_CLASSPATH, "lib/core/jasperreports-1.3.0.jar");

        return JasperCompileManager.writeReportToXml(JasperCompileManager.compileReport(design));
    }
}

and

Hi Teodor,

Thank you for looking into this issue.

For me also, the Firefox Print Preview looks ok - with no black background regions. The issue of black backgrounds actually occurs after pressing 'Print' in Firefox: the page prints with black background regions around the charts and similarly my printer's 'print preview' window displays the black backround regions.

Would it be possible for you to test printing out the sample pie chart you referred to using the Firefox print button?

Thanks again.

I have jfreecharts which are displayed in HTML and can be printed via the browser's print button.

The problem is in Mozilla Firefox, when a chart is printed, the key area below the chart prints with a black background. Please see the attached screenshot.

I have the following code snippets below (shown in red font) which make the main part of the report background print as white in Firefox. Is there someway to specify that the key area should be white also?

JRDesignChart chart = new JRDesignChart(null, chartType);

chart.setBackcolor(Color.WHITE);

...

JRHtmlExporter exporter = new JRHtmlExporter();

exporter.setParameter(JRHtmlExporterParameter.JASPER_PRINT_LIST, listOfPrints);

exporter.setParameter(JRHtmlExporterParameter.IMAGES_URI, request.getContextPath()+"/ctx/auth/dashboardimage?image=");

exporter.setParameter(JRHtmlExporterParameter.IS_WHITE_PAGE_BACKGROUND, Boolean.TRUE);

...

[file name=chart_print_preview_from_firefox.jpg size=44100]http://www.jasperforge.org/components/com_joomlaboard/uploaded/files/chart_print_preview_from_firefox.jpg[/file]

I also tried:

chart.getPlot().setBackcolor(Color.WHITE);

chart.getPlot().setBackgroundAlpha(1.0f);

But still no luck when printing from Firefox!

The area's outside the plots are still black, so for bar charts, the axis detail can't be seen in the print; for pie charts, the key area under the chart can't be seen in the print.

One thing I noticed: in IE browser, the chart image is rendered as a bitmap (this prints ok) - in the Firefox browser, the chart image is rendered as a .png image with transparent regions to the left and underneath chart area - these print as black regions.

Any ideas anyone? Teodor?

How can I implement a dialog window for users to be prompted to enter in data before a report is run?

I have the following code snippets:

(1) java code for the parameter(s):

Code:

Map map = new HashMap();
map.put("START_DATE", new Date());
...

(2) parameters in template:

Code:

[code]<parameter name="START_DATE" isForPrompting="true" class="java.util.Date" >
<parameterDescription><![CDATA["Please enter a Start Date (mm/dd/yyyy)"]]></parameterDescription>
</parameter>

When I run the report, no dialog window appears. Can you please give details on how to implement a simple dialog window for this?
