How to show an image on jasper report?

by

I do it this way – image is passed by path:

HashMap<String, Object> params = new HashMap<String, Object>();
params.put("logo", ClassLoader.getSystemResource("logo.jpg").getPath());

.jrxml

<parameter name="logo" class="java.lang.String"/>
...
<image>
    <reportElement x="0" y="1" width="100" height="37"/>
    <imageExpression><![CDATA[$P{logo}]]></imageExpression>
</image>

…or image is passed as InputStream (I don’t know why, but <image> need to have onErrorType attribute set to "Blank", otherwise it does not work – throws exception):

HashMap<String, Object> params = new HashMap<String, Object>();
params.put("logo", ClassLoader.getSystemResourceAsStream("logo.jpg"));

.jrxml

<parameter name="logo" class="java.io.InputStream"/>
...
<image onErrorType="Blank">
    <reportElement x="0" y="1" width="100" height="37"/>
    <imageExpression><![CDATA[$P{logo}]]></imageExpression>
</image>
