display image in jasper report

[mathewrond]

Hi,

I have a XML file as Database and I am using xPath to read the xml file.

 

I am trying to display an image in the report and the xml file gives me a string value which I need to use and display the image.

 

The image is located in APP-INF/classes folder of .ear file.

 

Here is what I have tried and it doesn't display me the image.

 

Code:

				<image  evaluationTime="Now" hyperlinkType="None"  hyperlinkTarget="Self" >
					<reportElement
						x="7"
						y="6"
						width="140"
						height="40"
						key="image-1"/>
					<box topBorder="None" topBorderColor="#000000" leftBorder="None" leftBorderColor="#000000" rightBorder="None" rightBorderColor="#000000" bottomBorder="None" bottomBorderColor="#000000"/>
					<graphicElement stretchType="NoStretch"/>
					<imageExpression class="java.lang.String"><![CDATA[$F{Logo}]]></imageExpression>
				</image>

 

Is there a way to get the image displayed?

[mathewrond]

I have read in most of the forums that if the Image is in classpath then relative path should work.

 

 

In my case the image is in classpath i.e. in APP-INF/classes folder. But why is it not getting loaded?

 

 

Any ideas would be helpful.

Can you give a concrete example of an image location under APP-INF/classes and the image expression you are using?

Hi,

I read an XML file to get information so I use XPath to query the XML file.

 

 

<LOGO>logo.gif</LOGO> - tag in XML File

 

 

The value that I get from the XML file is

 

 

logo.gif

 

 

Below is my field and image tag in jrxml file

 

Code:

<field name="Logo" class="java.lang.String">
	<fieldDescription><![CDATA[//Logo]]></fieldDescription>
</field>

<image  evaluationTime="Now" hyperlinkType="None"  hyperlinkTarget="Self" >
	<reportElement
		x="7"
		y="6"
		width="140"
		height="40"
		key="image-1"/>
	<box topBorder="None" topBorderColor="#000000" leftBorder="None" leftBorderColor="#000000" rightBorder="None" rightBorderColor="#000000" bottomBorder="None" bottomBorderColor="#000000"/>
	<graphicElement stretchType="NoStretch"/>
	<imageExpression class="java.lang.String"><![CDATA[$F{Logo}]]></imageExpression>
</image>

 

 

My image is located in APP-INF/classes/logo.gif

 

 

I have placed all my .jasper files in the same APP-INF folder and I am able to load them in the java code.

 

 

But the image has to be loaded from .jasper file and I am not able to get it.

Are you able to load the image from your java code? If so, can you post the code you use to load it?

[mathewrond]

No, I am not loading the image from the java code but I am loading .jasper files from APP-INF/classes/jasper/*.. and here is the code that I used for it.

 

Code:

InputStream designFormatInputStream = null;
designFormatInputStream = this.getClass().getClassLoader()
	.getResourceAsStream("f1.jasper");
jasperReport = (JasperReport) JRLoader.loadObject(designFormatInputStream);

My query was whether you could try to load the image from java code and see whether it works or not, maybe this would have helped finding the cause of the problem..

 

Anyway, you could try doing

Code:

params.put(JRParameter.REPORT_CLASS_LOADER, this.getClass().getClassLoader());

when filling the report, maybe this will help..

Hi,

Thanks for the suggestion. I have tried by putting the extra parameter before fill but I still am not able to see the image.

 

I will try your other suggestion of loading the image from java code and see if it helps.

Hi,

         Please used the below mentioned code for Image Displaying. Please pass the argument with image name.

         Parameter name is "IMAGE_DIR".

 

HashMap<String,Object> jasperParameter = new HashMap<String,Object>();

jasperParameter.put("SUBREPORT_DIR",jrxmlSourceLocation);

jasperParameter.put("IMAGE_DIR",ImageDir);

if(reportFormat.equalsIgnoreCase(ReportConstansts.FORMAT_HTML) || reportFormat.equalsIgnoreCase(ReportConstansts.FORMAT_EXCEL)){

jasperParameter.put(JRParameter.IS_IGNORE_PAGINATION, Boolean.TRUE);

}

 

File fname = new File(destinationPath + FILE_SEPARATOR + filename+ReportConstansts.EXCEL_EXT);

JRXlsExporter jRXlsExporter = new JRXlsExporter(); 

jRXlsExporter.setParameter(JRXlsExporterParameter.IS_WHITE_PAGE_BACKGROUND, Boolean.FALSE); 

jRXlsExporter.setParameter(JRXlsExporterParameter.IS_IGNORE_CELL_BORDER,Boolean.TRUE); 

jRXlsExporter.setParameter(JRXlsExporterParameter.IS_ONE_PAGE_PER_SHEET,Boolean.FALSE); 

jRXlsExporter.setParameter(JRXlsExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS,Boolean.TRUE); 

jRXlsExporter.setParameter(JRXlsExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_COLUMNS,Boolean.TRUE);

jRXlsExporter.setParameter(JRXlsExporterParameter.IS_DETECT_CELL_TYPE,Boolean.TRUE);

jRXlsExporter.setParameter(JRXlsExporterParameter.OFFSET_X,0); 

jRXlsExporter.setParameter(JRXlsExporterParameter.OFFSET_Y,0); 

jRXlsExporter.setParameter(JRXlsExporterParameter.IS_DETECT_CELL_TYPE,Boolean.TRUE);

jRXlsExporter.setParameter(JRXlsExporterParameter.JASPER_PRINT_LIST, jprintlist);

jRXlsExporter.setParameter(JRXlsExporterParameter.SHEET_NAMES,ReportConstansts.TAB_NAMES);

jRXlsExporter.setParameter(JRXlsExporterParameter.OUTPUT_FILE_NAME,fname.toString());

try {

jRXlsExporter.exportReport();

} catch (JRException ex) {

logger.log(ILogger.LEVEL_SEVERE,"Exception occured while exporting the JasperReport:"+ex.getMessage(),null,ex);

          

   }

Thanks,
