Merge several reports / have several report chapters -

how can merge or concatenate several jrxml jasperreports 1 report unit,

without using java code?

i can upload jrxml files , generate report units rest api / webservice only.

or there other solution element layout?

--header-- * group of countries     england     australia     croatia * pie chart countries --footer--  --new page--  --header-- * group of else     1     else 2     .... * chart of else --footer-- 

i think of having array variable iterate on <group> element , print sub report each element. like:

<variable name="chapters" class="java.util.list" resettype="none" resetgroup="chaptergroup" incrementtype="group" incrementgroup="browsergroup">     <variableexpression>         <![cdata[java.util.arrays.aslist("browser", "country")]]>                </variableexpression>     <initialvalueexpression>         <![cdata[new java.util.arraylist()]]>     </initialvalueexpression> </variable>  <group name="chaptergroup" isstartnewpage="true" keeptogether="true">     <groupexpression><![cdata[$v{chapters}]]></groupexpression>     <groupheader>         <band height="20" splittype="stretch"/>     </groupheader>     <groupfooter>         <band height="20" splittype="stretch">   <subreport>     <reportelement isprintrepeatedvalues="false" x="5" y="25" width="325" height="20" isremovelinewhenblank="true" backcolor="#ffcc99"/>     <subreportparameter name="<![cdata[$v{chapters}]]>">         <subreportparameterexpression><![cdata[$v{chapters}]]></subreportparameterexpression>     </subreportparameter>     <connectionexpression><![cdata[$p{report_connection}]]></connectionexpression>     <subreportexpression class="net.sf.jasperreports.engine.jasperreport"><![cdata["repo:/reports/" + $v{chapters}]]></subreportexpression>   </subreport> 

but can't work..

using jasper report server 5, (i code jrxml myself, , use ireports preview). same datasource everything, 2 queries 2 grouping sections charts.

this can done adding report groups, can add many report groups want per chart , keep header , footer in same report group every chart , every report group have sub dataset. have combined 5 report different header , footer.

you can see sample report provided jaspersoft name " standard chart report" under reports directory.

to :- 1:- add dataset 2:- add report group 3:- drag chart palette

here code sample, in code sample combining bar chart , stacked bar chart in 2 pages 2 different sub dataset :-

    <group name="bar">     <groupexpression><![cdata[null]]></groupexpression>     <groupheader>         <band height="400">             <barchart>                 <chart evaluationtime="report">                     <reportelement x="0" y="0" width="555" height="300"/>                     <charttitle>                         <titleexpression><![cdata["bar chart"]]></titleexpression>                     </charttitle>                     <chartsubtitle>                         <subtitleexpression><![cdata["chart displaying bars"]]></subtitleexpression>                     </chartsubtitle>                     <chartlegend/>                     <hyperlinktooltipexpression><![cdata["bar chart"]]></hyperlinktooltipexpression>                 </chart>                 <categorydataset>                     <dataset incrementtype="group" incrementgroup="salesstate">                         <datasetrun subdataset="categorydataset"/>                     </dataset>                     <categoryseries>                         <seriesexpression><![cdata[$f{sales_state}]]></seriesexpression>                         <categoryexpression><![cdata[$f{full_name}]]></categoryexpression>                         <valueexpression><![cdata[$v{personamount}]]></valueexpression>                     </categoryseries>                 </categorydataset>                 <barplot>                     <plot/>                     <itemlabel/>                     <categoryaxislabelexpression><![cdata["name"]]></categoryaxislabelexpression>                     <valueaxislabelexpression><![cdata["amount"]]></valueaxislabelexpression>                 </barplot>             </barchart>         </band>     </groupheader> </group> <group name="stackedbar">     <groupexpression><![cdata[null]]></groupexpression>     <groupheader>         <band height="400">             <stackedbarchart>                 <chart evaluationtime="report">                     <reportelement x="0" y="0" width="555" height="300"/>                     <charttitle>                         <titleexpression><![cdata["stacked bar chart"]]></titleexpression>                     </charttitle>                     <chartsubtitle>                         <subtitleexpression><![cdata["chart displaying stacked bars"]]></subtitleexpression>                     </chartsubtitle>                     <chartlegend/>                     <hyperlinktooltipexpression><![cdata["stacked bar chart"]]></hyperlinktooltipexpression>                 </chart>                 <categorydataset>                     <dataset incrementtype="group" incrementgroup="salesstate">                         <datasetrun subdataset="categorydataset"/>                     </dataset>                     <categoryseries>                         <seriesexpression><![cdata[$f{sales_state}]]></seriesexpression>                         <categoryexpression><![cdata[$f{full_name}]]></categoryexpression>                         <valueexpression><![cdata[$v{personamount}]]></valueexpression>                     </categoryseries>                 </categorydataset>                 <barplot>                     <plot/>                     <itemlabel/>                     <categoryaxislabelexpression><![cdata["name"]]></categoryaxislabelexpression>                     <valueaxislabelexpression><![cdata["amount"]]></valueaxislabelexpression>                 </barplot>             </stackedbarchart>         </band>     </groupheader> </group>
