relativepath image Jasperreport

[Luis Parente]

Hello,

In an application I'm trying to make a report for each item in a list that I get from a BDD.

Each page must contain a logo .....

I tried to put the image in the beginning of all the pages .....
As in my jrxml the relative path is not appreciated. EX:

./logo.gif

After a little google I pass the image in the map like this:

parameterMap.put("logo", this.getClass().getResourceAsStream(jasperLogoPath));

then in the jrxml I reporting this parameter:

<parameter name="logo" class="java.io.InputStream"/>

then for display:

<image onErrorType="Blank">
				<reportElement uuid="9de2450b-68b7-4c44-a545-2d21c6f93f30" isPrintRepeatedValues="false" x="60" y="0" width="162" height="43"/>
				<imageExpression><![CDATA[$P{logo}]]></imageExpression>
			</image>

I don't know why, but <image> need to have onErrorType attribute set to "Blank", otherwise it does not work - throws exception


If I try to print multiple times this parameter (logo) does not work and I do not understand why? It is display only one time.

Thanks in advance.
