Hi,
I am trying to do a simple prototype of generating an image on the server and displaying it on a listgrid using DMI. I adapted what I found on the forum as follows:
ds.xml:
<DataSource
ID="testDMI"
serverType="generic"
>
<fields>
<field name="imageTest" title="Test image" type="imageFile" required="false" showFileInline="true">
</field>
</fields>
<serverObject lookupStyle="new" className="com.smartgwt.sample.server.TestDMI"/>
<!-- You can define an operationBindings section to bind operation names to server method
(potentially additionally discriminated by the operationId).
In the absense of this section, the server will look for a server method named after
the operationType.
-->
<serverObject lookupStyle="new" className="com.smartgwt.sample.server.TestDMI" />
<operationBindings>
<binding operationType="viewFile" serverMethod="viewFile">
<serverObject lookupStyle="new" className="com.smartgwt.sample.server.TestDMI" />
</binding>
</operationBindings>
<operationBindings>
<binding operationType="fetch" serverMethod="fetch">
<serverObject lookupStyle="new" className="com.smartgwt.sample.server.TestDMI"/>
</binding>
</operationBindings>
</DataSource>
TestDMI:
public class TestDMI {
List<Map<String,Object>> imageData = new ArrayList<Map<String, Object>>();
InputStream imageStream = null;
public DSResponse fetch(DSRequest dsRequest)
throws Exception
{
Logger log = new Logger(TestDMI.class.getName());
File file = new File(dsRequest.getServletContext().getRealPath("/images/pdda1.png"));
imageStream = new BufferedInputStream( new FileInputStream(file) );
HashMap<String, Object> hm = new HashMap<String, Object>();
//hm.put("image", imageStream);
hm.put("imageTest_filename", file.getName());
hm.put("imageTest_filesize", file.length());
imageData.add(hm);
DSResponse response = new DSResponse();
response.setDataSource(dsRequest.getDataSource());
response.setSuccess();
response.setTotalRows(1);
response.setData(imageData);
response.setStartRow(0);
response.setEndRow(1);
response.setData(imageData);
return response;
}
public DSResponse viewFile(DSRequest dsRequest, RPCManager rpcManager) throws Exception {
File file = new File(dsRequest.getServletContext().getRealPath("/images/pdda1.png"));
imageStream = new BufferedInputStream( new FileInputStream(file) );
HashMap<String, Object> hm = new HashMap<String, Object>();
hm.put("imageTest", imageStream);
hm.put("imageTest_filename", file.getName());
hm.put("imageTest_filesize", file.length());
imageData.add(hm);
DSResponse response = new DSResponse();
response.setDataSource(dsRequest.getDataSource());
response.setSuccess();
response.setTotalRows(1);
response.setStartRow(0);
response.setEndRow(1);
response.setData(imageData);
return response;
}
}
client:
@Override
public void onModuleLoad() {
DataSource dataSource = DataSource.get("testDMI");
VStack vStack = new VStack();
vStack.setLeft(175);
vStack.setTop(75);
vStack.setWidth("70%");
vStack.setMembersMargin(20);
final ListGrid boundList = new ListGrid();
boundList.setDataSource(dataSource);
boundList.setHeight(200);
boundList.setCanEdit(true);
boundList.fetchData();
vStack.addMember(boundList);
vStack.draw();
}
We get the following exception:
