Error evaluating expression for Integer.valueOf($P{string})

[philipp.fresen]

hey folks,

i get an evaluation error for parsing a string to an int with "Integer.valueOf(<string-param>)".

<parameter name="s_incident" class="java.lang.String" isForPrompting="false">    <defaultValueExpression>        ![CDATA[new String("")]]    </defaultValueExpression></parameter><parameter name="q_incident" class="java.lang.Integer" isForPrompting="false">    <defaultValueExpression>        ![CDATA[iF($P{s_incident}.trim().length() > 0,Integer.valueOf($P{s_incident}),new java.lang.Integer(0))]]    </defaultValueExpression></parameter>[/code]

the string parameter is used as input control in the JasperReporting Server (i want the field to be blank at the beginning).

the int parameter is used in the sql query.

Hope someone can help me..

best regards, Philipp

The problem is based on the empty default value of the string parameter.

 

does anyone know how the default value for an integer is in Jasper?

I would use following as Default Expression for your Integer Parameter:

$P{s_incident} == null || "".equals($P{s_incident}.trim())? new Integer(0) : Integer.valueOf($P{s_incident})
