Dividing Parameters and FIelds

2003-04-17 10:39

I am still fairly new to JAVA and Jasper. I have a report in which I am trying to compute a percentage. One value comes from a field and the other comes from a parameter. Both are class java.lang.Long. I want to divide them and display the result. But I get errors.

 

Here is my code:

 

<variableExpression>$F{COUNT}</variableExpression>

 

<initialValueExpression>$F{COUNT}==null?1:$F{COUNT}</initialValueExpression>

</variable>

<variable name="vPercent" class="java.lang.Long" resetType="None" calculation="Nothing">

<variableExpression>$F{COUNT}.toLong()/$P{TOTAL}.toLong()</variableExpression>

<initialValueExpression>$F{COUNT}.toLong()/$P{TOTAL}.toLong()</initialValueExpression>

</variable>

 

 

<group name="LocationGroup">

<groupExpression>$F{SHORT_DESCRIPTION}</groupExpression>

<groupHeader>

<band height="30">

<textField>

<reportElement positionType="Float" x="3" y="0" width="172" height="30"/>

<textElement textAlignment="Left">

</textElement>

<textFieldExpression class="java.lang.String"><![CDATA[$F{SHORT_DESCRIPTION}]]></textFieldExpression>

</textField>

<textField>

<reportElement positionType="Float" x="183" y="0" width="42" height="30"/>

<textElement textAlignment="Left">

</textElement>

<textFieldExpression class="java.lang.Long"><![CDATA[$F{COUNT}==null?new java.lang.Long(0):$F{COUNT}]]></textFieldExpression>

 

</textField>

 

<textField>

<reportElement positionType="Float" x="225" y="0" width="42" height="30"/>

<textElement textAlignment="Left">

</textElement>

<textFieldExpression class="java.lang.Long">($F{COUNT}==null)?new java.lang.Long(0):($F{COUNT}.longValue()/$P{TOTAL}.longValue())></textFieldExpression>

</textField>

 

.

.

.

 

 

 

Here are some errors:

Hi,

 

The result has to be an object, not a primitive type:

 

<variableExpression>

new Long(

$F{COUNT}.toLong() / $P{TOTAL}.toLong()

)

</variableExpression>

 

I hope this helps.

Teodor
