        // Method required for reading the dataset.

Please, can someone tell me, how can we specify the class path on server ???

I did lot of reading and surfing but have not found anything.

Hello all,

I have a report with parameters using customized class. Report is working fine in i-report and jasper server reporsitory plugin too.

I have added my .jar file that contains the class in "Add resources" section of server. But when I am running its throwing me an error saying "Error evaluating expression $P{dateUtils}.getEndDate( $P{DateChoice}, $P{Time_Interval}, $P{InputDate})". In the parameter I have specified the class which is com.redhat.eng.JasperDateUtils.

I am wondering why is it not working in japser server. Most probably, it is not able to get the classpath.

Please help...

Hi everyone,

I have solved my problem. If anyone needs the code, feel free to aske me.

February 1, 2012

I want to have the stacked bar chart colors based upon their series values .

Like for "A" -- red

"B" --- yellow

"C" --- green

As I am a beginner in creating jasper class, I tried my best and came up with this code..

public class BarColors extends JRAbstractChartCustomizer implements JRChartCustomizer
{
     public class CustomBarRenderer extends BarRenderer {

public CustomBarRenderer()
{
    super();
}

public Paint getItemPaint(int row, int column)
{
    CategoryDataset cd = getPlot().getDataset();

        if (cd != null)
        { String l_rowKey = (String)cd.getRowKey(row);
           String l_colKey = (String)cd.getColumnKey(column);
      double result = cd.getValue(l_rowKey, l_colKey).doubleValue();
             String eg = Double.toString(result);

    if (eg.equals("A")) {
          new Color(0xE4, 0x1B, 0x1B); }
else if (eg.equals("B"))
        {new Color(0xF1, 0xAB, 0x10); }
else if (eg.equals("C"))
          { new Color(0xEF, 0xC3, 0x5A); }
else if (eg.equals("D"))
           {new Color(0x0B, 0x2E, 0xF0);}
else { }

   }

    return (Paint)cd;

}

}

public void customize(JFreeChart chart, JRChart jasperchart) {

       // get the "plot" from the JFreeChart

CategoryPlot categoryplot = (CategoryPlot)chart.getCategoryPlot();

       // get the dataset

CategoryDataset cd = (CategoryDataset)categoryplot.getDataset();

CustomBarRenderer renderer = new CustomBarRenderer();

chart.getCategoryPlot().setRenderer(renderer);

}

}

It build succesfully as .jar file but when I am executing in the report report is blank and showing error(though report is working fine without customize class).

I am sure that code has errors in it. Please, help me It's very urgent for me. Any suggestions/comments are appreciable.

Thanks

Hello all,

I have a date parameter in my report called Auto_Date:

Set curdate as default value when null or empty string. Report is working fine in i-report but when I am scheduling on Japser server by leaving visible Auto_Date parameter blank, report is empty. I know that if I will set parameter as "Read-only" on server I can schedule it. My limitation is that I cannot have two jrxml file one for random date and one for scheduling. It is driving me crazy, I have searched all the forum but did not find any answer. Can I schedule my report by using default value of parameter.

Please help, it' svery important for me.

Thanks

Hello All,

I got sucess in creating report having multiple input parameter on serevr. But I want that instead of running my report for all

multiple inputs at same time, it should run for each single input each time. For eg: I put three multiple inputs parameter---

A, B, C. Right now, Query and Report is running for A, B, and C together. Instead, I want query and report should execute first

for A, then B, and then C.

I don't have any way, how to do. All suggestions are highly appreciable.

I have attached my .jrxml file.

Please, help me ... its urgent for me

Thanks in advance..

Hello All,

I am wondering if someone can help me. I need to fix series colors according to the field values. Suppose i have four fields..

A - Black,

B- Red,

C-Green,

D - Yellow.

If all the fields are present then everything is fine. But, if one field is missing in between, then order is changing and that I don't wish to have. Like if B is not present then the results is :

A-Black,

C-Red,

D - Green.

How can I force them to have fields their specific colors. I read a lot study of old threads and forums but did not get an answer.

Please, help me. Any suggestions would be appreciable.

Thanks

Hello all,

I need help and guidance of experts in i-report for a newbie.

I need a variable (or text expression) having one maximum value from all the fileds.

For ex:

I have four fields. Let's say A , B, C , D . So the variable should get maximum value from all these fields. A > B> C > D. All these are an integer.

I am able to get the maximum value for a field like A . But I am not able to get the maximum value from all the fields. How can I get this? I tried various text expressions but no luck.

Please help, it's very urgent and important for me.

Thanks in advance

Hello all,

I need to create a parameter for my report to which I can give value either in days(1, 2, 3, ...30) or in months (like Jan(01), Feb(02), March(03)) or in years (2011, 2010). This means that I need to set parameter having multiple units so that user will have choice. Can we do it in single parameter,? If yes, then please tell me how?

Thanks in advance..
