Help in Create PJC to get image from Scanner

Question

Help
I'm tring to use JTwain java library to scan an image directly to the form ,
i got the DLL and the java files and use it to run and test the Demo program from dos
It works , then i tried to make a PJC to use that class
the PJC Bean Extends the VImage class With 2 properties
a SET Property SELECT_SOURCE
a GET Property ACQUIRE
I'm trying to run those property's function from 2 Buttons in the form , not in the initialization
and create a Bean Area in my Form to use that class,
the classes compiled and made a JAR file in <DEVSUITE_HOME>/forms/java directory
After the compilation of the PJC , deployment and add the JAR file to formsweb.cfg.
when i'm tried to run my form
the form give me that error "FRM-92100" before it's load.
my Bean Code as Follow
package net.javajeff.jtwain;
import java.awt.Image;
import oracle.forms.handler.IHandler;
import oracle.forms.ui.CustomEvent;
import oracle.forms.properties.ID;
import oracle.forms.ui.VImage;
public class MYVImage extends VImage
static IHandler mHandler;
// SET
protected static final ID SELECT_SOURCE = ID.registerProperty("SELECT_SOURCE");
// GET
protected static final ID ACQUIRE = ID.registerProperty("ACQUIRE");
public MYVImage()
try
jbInit();
catch(Exception e)
e.printStackTrace();
public boolean setProperty(ID property, Object value) {
if(property == SELECT_SOURCE) {
JTwain JT =new JTwain();
try{JT.selectSourceAsDefault();}
catch(Exception e){}
return true;}
return true;
public Object getProperty(ID property) {
JTwain JT =new JTwain();
if (property == ACQUIRE)
try{
this.setImage(JT.acquire());
catch(Exception e){}
} else
return super.getProperty(property);
return null;
private void jbInit() throws Exception
The Jtwain Code is working in dos ,it returns Java.awt.image from The ACQUIRE function
i used it in the bean to set it's image
the Twain class code
package net.javajeff.jtwain;
import java.awt.Image;
* This class provides the "glue" to connect the Java side of JTWAIN to the
* C++ side. Methods exist to initialize JTwain and interact with TWAIN.
* @author Jeff Friesen
public class JTwain
* Initialize JTwain. Initialization succeeds if System.loadLibrary() is
* able to find the jtwain library, if the jtwain library is able to find
* TWAIN_32.DLL, and if TWAIN_32.DLL contains the DSM_Entry() function. A
* messagebox is displayed if either TWAIN_32.DLL or DSM_Entry() can't be
* found.
* IMPORTANT: This method must be called before any other method. If this
* method returns false, do NOT call any other method.
* @return true if JTwain successfully initialized, otherwise false
public static boolean init ()
try
System.loadLibrary ("jtwain");
return true;
catch (UnsatisfiedLinkError e)
return false;
* Display the default source's dialog box to let the user configure that
* source. If the user clicks the Scan button, acquire one image from the
* default source.
* @return Image that describes the acquired image, otherwise null if the
* user clicked the Cancel button on the default source's dialog box
* @throws JTwainException if something goes wrong
public static native Image acquire () throws JTwainException;
* Select a source name from the source manager's dialog box. If the user
* clicks the Ok button, the highlighted source name becomes the new
* default source.
* @throws JTwainException if something goes wrong
public static native void selectSourceAsDefault () throws JTwainException;
Please help, i need to scan an image directly to the form image item
if there is another way somebody heeeelp

here's a snippet of code
-- create your type in Oracle via sqlplus
     CREATE OR REPLACE TYPE STRING_ARRAY         AS VARRAY(999) OF VARCHAR2(128);
// in your java code
String[] arParam = { "FOO", "BAR" };
oracle.sql.ArrayDescriptor arDesc = ArrayDescriptor.createDescriptor(
"<yourSchemaOwnerGoesHere>" + "." + "STRING_ARRAY",
<yourConnectionObject> );
ARRAY oracleArray = new ARRAY(arDesc, <yourConnectionObject>, arParam );
                            <yourPreparedOrCallableStatement>.setARRAY(1, oracleArray);
or use registerOut if you want to get a return value
