Hi all,
I have create a Jasper-Report with a lot of text fields and for the moment all works fine.

Now I have the necessity to integrate a SVG field to rappresent a drawing.
I define an image in the report and one parameter to transfer SVG data, but return to me un exception

In my report I define the parameter and the element in the follow way:

	<parameter name="ShapeImage" class="net.sf.jasperreports.engine.JRRenderable" isForPrompting="false">
		<parameterDescription><![CDATA[]]></parameterDescription>
	</parameter>

...
	<image hAlign="Center" vAlign="Middle">
		<reportElement x="2" y="106" width="551" height="186" uuid="0407b952-8088-4146-9dfc-b61f71e78201"/>
		<graphicElement/> 
		<imageExpression class="net.sf.jasperreports.engine.JRRenderable"><![CDATA[$P{ShapeImage}]]></imageExpression>
	</image>
...

I try with parameter with class="net.sf.jasperreports.engine.JRRenderable" or ="java.lang.String" or ="java.awt.Image", but everytime return to me an exception.

The SVG information is stored into a String that I pass at this parameter; below you find an example of this string

I work with Java with IDE Eclipse Juno 3.8 and Jasperstudio 5.5.2.

I think my mistake is in step as I pass the data to the parameter, but I cannot figure out exactly what and where. In my application the SVG data is defined as String, how can manage it with the corrisponding paramert in Jasper-Report?
I have also the following question : when I haven't this information to create SVG data, how can manage the corrisponding parameter in Jasper-Report?

Thanks in advance for any help and explanation

Hi,
I solved this problem.

An help is on this links:

https://www.linuxnet.ch/jasper-reports-inline-images-as-svg-for-better-scaling/

and

http://community.jaspersoft.com/questions/525861/how-use-svg-jasperreports

If you have/use a inline SVG string instead of SVG file, as showed in this links, it's necessary use this net.sf.jasperreports.renderers.BatikRenderer.getInstanceFromText in your report definition.

Example of my .jrxml:

...
	<parameter name="ShapeImage" class="java.lang.String" isForPrompting="false">
		<parameterDescription><![CDATA[]]></parameterDescription>
	</parameter>

...
	<image hAlign="Center" vAlign="Middle">
		<reportElement x="2" y="106" width="551" height="186" uuid="0407b952-8088-4146-9dfc-b61f71e78201"/>
		<imageExpression><![CDATA[net.sf.jasperreports.renderers.BatikRenderer.getInstanceFromText($P{ShapeImage})]]></imageExpression>
	</image>
</frame>
...
