report templates

[sgolestane]

To eliminate duplication and provide consistance look and feel across all reports i've decided to  remove style defenitions from .jrxml files and define them in java and pass them to JasperPrint at run time as JRParameter.REPORT_TEMPLATES parameter.

reports can include sub reports.

I've bean successfull to do this for the main report but havn't found a way pass these templates to sub reports.

any suggestion?

OK i found a solution for this:

1. Create a calss that implements net.sf.jasperreports.engine.JRTemplate and setup styles in that class. (see ACMETemplate)
2. include this class as a template element in your jrxml file :<template class="net.sf.jasperreports.engine.JRTemplate"><![CDATA[new acme.jasper.ACMETemplate()]]></template>

doing this you can control style of all your reports in a single defenition class.

Code:

package acme.jasper;import java.awt.Color;import net.sf.jasperreports.engine.JRAlignment;import net.sf.jasperreports.engine.JRElement;import net.sf.jasperreports.engine.JRException;import net.sf.jasperreports.engine.JRSimpleTemplate;import net.sf.jasperreports.engine.design.JRDesignStyle;public class ACMETemplate extends JRSimpleTemplate{    public MarchexTemplate() throws JRException    {        super();        Color blue = new Color(123, 177, 208);        JRDesignStyle defultStyle = new JRDesignStyle();        defultStyle.setName("defult");        defultStyle.setDefault(true);        defultStyle.setFontName("Arial");        defultStyle.setFontSize(12);        defultStyle.setVerticalAlignment(JRAlignment.VERTICAL_ALIGN_MIDDLE);        defultStyle.setMode(JRElement.MODE_OPAQUE);        addStyle(defultStyle);        JRDesignStyle tableTitleStyle = new JRDesignStyle();        tableTitleStyle.setParentStyle(defultStyle);        tableTitleStyle.setName("tableTitle");        tableTitleStyle.setBold(true);        addStyle(tableTitleStyle);        JRDesignStyle topHeaderStyle = new JRDesignStyle();        topHeaderStyle.setParentStyle(defultStyle);        topHeaderStyle.setName("topHeader");        topHeaderStyle.setBold(true);        topHeaderStyle.setBackcolor(blue);        topHeaderStyle.getLineBox().setLeftPadding(5);        topHeaderStyle.getLineBox().setRightPadding(5);        addStyle(topHeaderStyle);        JRDesignStyle cellStyle = new JRDesignStyle();        cellStyle.setParentStyle(defultStyle);        cellStyle.setName("cell");        cellStyle.setHorizontalAlignment(JRAlignment.HORIZONTAL_ALIGN_RIGHT);        cellStyle.getLineBox().setLeftPadding(5);        cellStyle.getLineBox().setRightPadding(5);        cellStyle.getLineBox().getTopPen().setLineColor(blue);        cellStyle.getLineBox().getTopPen().setLineWidth(0);        cellStyle.getLineBox().getLeftPen().setLineColor(blue);        cellStyle.getLineBox().getLeftPen().setLineWidth(0.25F);        cellStyle.getLineBox().getBottomPen().setLineColor(blue);        cellStyle.getLineBox().getBottomPen().setLineWidth(0.25F);        cellStyle.getLineBox().getRightPen().setLineColor(blue);        cellStyle.getLineBox().getRightPen().setLineWidth(0.25F);        addStyle(cellStyle);        JRDesignStyle leftHeaderStyle = new JRDesignStyle();        leftHeaderStyle.setParentStyle(defultStyle);        leftHeaderStyle.setName("leftHeader");        leftHeaderStyle.setHorizontalAlignment(JRAlignment.HORIZONTAL_ALIGN_LEFT);        leftHeaderStyle.setBackcolor(Color.LIGHT_GRAY);        leftHeaderStyle.getLineBox().setLeftPadding(5);        addStyle(leftHeaderStyle);        JRDesignStyle leftAlignCellStyle = new JRDesignStyle();        leftAlignCellStyle.setParentStyle(defultStyle);        leftAlignCellStyle.setName("leftAlignCell");        leftAlignCellStyle.setHorizontalAlignment(JRAlignment.HORIZONTAL_ALIGN_LEFT);        addStyle(leftAlignCellStyle);    }}
