Hi,

If you have a byte array, then create a resource from it then get the url of the resource and set this value with image UI's Resource Property. Some thing like this...

IWDResource webResource = null;

ByteArrayOutputStream bOut=new ByteArrayOutputStream();

now get the image into this bOut

webResource=rsf.createCachedResource(bOut.toByteArray(),"My Test",WDWebResourceType.JPG_IMAGE);

after this generate an URL for this resource and map it with image UI's Resource Property Say Va_Resouce

wdContext.CurrentContextElement().setVa_Resouce(webResource.getUrl(WDFileDownloadBehaviour.OPEN_INPLACE.ordinal()));

Thats it... you are done....

Hi,

Thanks for ur reply.

But i take that image in the form of byte [] from database.

byte[]	bOut=wdContext.currentWaElement().getEmp_Image();

		webResource=WDResourceFactory.createCachedResource(bOut,"My Test",WDWebResourceType.JPG_IMAGE);

		wdContext.currentResourcesElement().setUploadImgResource(webResource);
		wdContext.currentResourcesElement().setUploadImgURL(webResource.getUrl(WDFileDownloadBehaviour.OPEN_INPLACE.ordinal())	);

Hi,

find this below code...

byte[] imagebyte = null;

InputStream in=null;

try {

con=condb.getConnection (mgnr);

stmnt=con.createStatement();

rs=stmnt.executeQuery("select * from VMS_Image");

//Pass_No,name,Image

while(rs.next())

{

mgnr.reportSuccess("Name :"+rs.getString("name"));

imagebyte=rs.getBytes("Image");

in=rs.getBinaryStream("Image");

mgnr.reportSuccess("Image>>"+imagebyte);

ByteArrayOutputStream bOut=new ByteArrayOutputStream();

int lenght=0;

byte part[]=new byte[10*1024];

while((lenght=in.read(part))!=-1)

{

bOut.write(part,0,lenght);

}

in.close();

after this use the code which i gave earlier...
