Hi I created a jni jar and i call the jar using applet in java script. I use the following applet tag to create a object to call jar functions through java script. when i call the function i got the following error Object doesn't support this method or property.
Here is my code.
document.write('<applet code="BiomAPI.Legend.class" width="0" height="0" archive="BiomAPI.jar" id="Obj"></applet>');
function GetTemplateAccurate (sUserID,iFingerID)
{
document.getElementsByName("Enroll")[0].value = "";
document.getElementsByName("Image")[0].value = "";
var lsFeature = null;
var lsImage = null;
Obj.EnableLog(0);
Obj.LocalFilePath("C:\\IMAGE\\");
Obj.EnableEncryption(0);
Obj.SaveImage(1);
Obj.SessionID("abcdeabcdeabcdeabcdeabcdeabcdeabcdeabcdeabcdeabcdeabcde");
Obj.GetFeatureAccrual(sUserID,iFingerID);
lsFeature = Obj.Feature();
lsImage = Obj.StringImage();
if (lsFeature != null && lsImage != null )
{
document.getElementsByName("Enroll")[0].value = lsFeature;
document.getElementsByName("Image")[0].value = lsImage;
alert("Scanner Working Properly");
}
else
{
alert("Fingerprint not captured");
}
}
function GetTemplate(sUserID,iFingerID)
{
document.getElementsByName("Verify")[0].value = "";
var lsFeature = null;
Obj.EnableLog(0);
Obj.LocalFilePath("C:\\IMAGE\\");
Obj.EnableEncryption(0);
Obj.SessionID("abcde");
Obj.SaveImage(1);
Obj.GetFeature(sUserID,iFingerID);
lsFeature = Obj.Feature();
lsImage = Obj.StringImage();
if (lsFeature != null)
{
document.getElementsByName("Verify")[0].value = lsFeature;
alert("Scanner Working Properly");
}
else
{
alert("Fingerprint not captured");
}
}
as exception itself is describing:
Object doesn't support this method or property error
the property or method you are trying to access with an object is not supported by that object. Please debug or see on error console the object throwing exception and find whether it support that property you are trying to access.

I have the following situation:
a JKS keystore file without password, containing a private key ALSO unprotected. I've tried to configure Rampart in order to use this keystore, but i keep getting the following error:
Caused by: org.apache.rampart.RampartException: No password supplied by the callback handler for the user : "username"
my password callback handler is as follows:
public class PWCBHandlerCertificate implements CallbackHandler {
public void handle( Callback[] callbacks ) throws IOException, UnsupportedCallbackException {
for ( int i = 0; i < callbacks.length; i++ ) {
WSPasswordCallback pwcb = (WSPasswordCallback) callbacks[i];
String id = pwcb.getIdentifer();
int usage = pwcb.getUsage();
if ( usage == WSPasswordCallback.DECRYPT || usage == WSPasswordCallback.SIGNATURE ) {
Element temp = pwcb.getCustomToken();
// used to retrieve password for private key
if ( "username".equals( id ) ) {
pwcb.setPassword( "" );
}
}
}
}
}
what am i missing?
Thanks in advance
It turned out that rampart 1.5.2 (i don't know about newer versions, i must keep this one...) forces the certificate to have a valid password (not null and not empty).
I downloaded the source for rampart 1.5.2, and i found the following code inside the class BindingBuilder.java (package org.apache.rampart.builder):
WSPasswordCallback[] cb = { new WSPasswordCallback(user,
WSPasswordCallback.SIGNATURE) };
try {
handler.handle(cb);
if(cb[0].getPassword() != null && !"".equals(cb[0].getPassword())) {
password = cb[0].getPassword();
log.debug("Password : " + password);
} else {
//If there's no password then throw an exception
throw new RampartException("noPasswordForUser",
new String[]{user});
}
}
The problem resides here:
if(cb[0].getPassword() != null && !"".equals(cb[0].getPassword()))
The exception is thrown if the password is received null or empty from the callback. In order to avoid this problem i had to comment out a part of the code like this:
if(cb[0].getPassword() != null /*&& !"".equals(cb[0].getPassword())*/)
I recompiled the class and replaced the resulting .class inside rampart-core-1.5.2.jar
The exception disappeared, i can now successfully use the passwordless certificate.
I hope it helps.
I imported an Android sample coded by Amazon involving AWS's DynamoDB which I got from here and was presumably written for Eclipse:
https://github.com/awslabs/aws-sdk-android-samples/tree/master/DynamoDBMapper_UserPreference
Since Android Studio (0.8.1) uses gradle instead of ant, naturally things got auto-moved around in terms of dir structure when importing so (part of) it looks like this:
PropertyLoader gets the TVM credential info it needs to connect to the database DynamoDB from AwsCredentials.properties. Relevant methods:
public class PropertyLoader {
private boolean hasCredentials = false;
private String tokenVendingMachineURL = null;
private boolean useSSL = false;
private String testTableName = null;
private static PropertyLoader instance = null;
public static PropertyLoader getInstance() {
if ( instance == null ) {
instance = new PropertyLoader();
}
return instance;
}
public PropertyLoader() {
try {
Properties properties = new Properties();
properties.load( this.getClass().getResourceAsStream( "AwsCredentials.properties" ) );
this.tokenVendingMachineURL = properties.getProperty( "tokenVendingMachineURL" );
this.useSSL = Boolean.parseBoolean( properties.getProperty( "useSSL" ) );
this.testTableName = properties.getProperty( "testTableName" );
if ( this.tokenVendingMachineURL == null || this.tokenVendingMachineURL.equals( "" ) || this.tokenVendingMachineURL.equals( "CHANGEME" ) || this.testTableName.equals( "" ) ) {
this.tokenVendingMachineURL = null;
this.useSSL = false;
this.hasCredentials = false;
this.testTableName = null;
}
else {
this.hasCredentials = true;
}
}
catch ( Exception exception ) {
Log.e( "PropertyLoader", "Unable to read property file." );
}
}
However the getResourceAsStream line properties.load( this.getClass().getResourceAsStream( "AwsCredentials.properties" ) ); returns null. As you can see in my screenshot, AwsCredentials.properties is in the same dir as PropertyLoader and matches the case, which is all that should be required based on my readings of the method:
http://mindprod.com/jgloss/getresourceasstream.html
getResourceAsStream() is always returning null
I have tried other things such as prefixing "\" (i.e. properties.load( this.getClass().getResourceAsStream( "\AwsCredentials.properties" ) ); and copying the credentials file and placing in the src folder (you can't see it in this screenshot because the explorer sorts by filetype(?) and places 'main' first, but it's there) as per this:
getResourceAsStream returning null
However, that hasn't fixed the issue either. Having tried these options and done research, I'm confused as to why it's returning null. How can I fix this?
Created a dir called resources under /src/main/ and placed AwsCredentials.properties there and used
properties.load( PropertyLoader.class.getClassLoader().getResourceAsStream( "AwsCredentials.properties" ) );
instead of
properties.load( this.getClass().getResourceAsStream("AwsCredentials.properties" ) );
Not as elegant as I would like, but it works.
For up to a day I was struggling with this as well. And finally I was able to resolve this very neatly. The problem is not in the JAVA but in the all project structure. E.g. in Android Studio the whole project is under src/main/java whereas main is a flavour of the project. So if you've file(-s) to read from in source's package (e.g.) com/my/example/app you have to edit the build.gradle file for read (clazz.getResourceAsStream(file)) to work properly. I.e. under android define sourceSets like this:
android {
/* ... Your stuff ... */
sourceSets {
// Lets have two flavours to make it more clear
main {
resources.srcDirs = ['src/main/java']
}
flavourFoo {
resources.srcDirs = ['src/flavourFoo/java']
}
}
}
Hope this helps!
i'm tring to get all required features of specific app. i wrote this code
mPackageInfo = getPackageManager().getPackageInfo(packageName, 0);
mFeatures = mPackageInfo.reqFeatures;
if(mFeatures != null) {
for(FeatureInfo feature : mFeatures) {
mString.append(feature.name);
}
}
else {
Log.d("test", "error");
}
mFeatures is FeatureInfo[] variable. mString is StringBuffer type variable. in my logcat i see error. why? how can i solve?
Replace 0 in your getPackageInfo() call with PackageManager.GET_CONFIGURATIONS.
I want to openOrCreate database in SDcard / Media Card. When i run the application in device (BlackBerry Curve 8900), i find only one root i.e "system/" and running application in simulator (9500), i find three roots as shown in comment in code. I am getting error at;
_db = DatabaseFactory.openOrCreate(_uri);
(error: Method "toString" with signature "()Ljava/lang/String;" is not applicable on this object)
And i am not able to understand what is this error about.
Here is the code.
public void getValues() throws Exception
{
boolean sdCardPresent = false;
String root = null;
Enumeration e = FileSystemRegistry.listRoots();
while (e.hasMoreElements())
{
root = (String)e.nextElement();
System.out.println("Value of root::" +root); // value of root = "system/" when run in device and
// value of root = "store/" "SDCard/" "system/" when run in simulator
if(root.equalsIgnoreCase("system/"))
{
sdCardPresent = true;
}
}
System.out.println("--------------------getValues()----------------------------------");
URI _uri = URI.create(Global.DB_PATH + Global.DB_Main);
System.out.println("Valud of uri::" +_uri);
_db = DatabaseFactory.openOrCreate(_uri); //getting error here.
System.out.println("Valud of _db::" +_db);
_db.close();
I tried these three paths, getting output with "/store"(when run in simulator) but error with rest two paths.Even using "/store" in device is showing the same error.
Global.DB_PATH = "/MediaCard/databases/";
Global.DB_PATH = "/SDCard/databases/";
Global.DB_PATH = "/store/databases/";
Is there any way how to get SDCard/Media Card as root so that i can copy the database in there?
My guess is when you are running your app on a real device you have USB cable plugged in to the device. If this is the case, try to unplug the cable and rerun the app. You may use Dialog.inform() to quickly check what roots you get this time.
private ObjectListField getFileList() {
if (fileList == null) {
fileList = new ObjectListField();
String[] roots = new String[3];
Enumeration enum = FileSystemRegistry.listRoots();
int x = 0;
while (enum.hasMoreElements()) {
if (x < 3) {
roots[x] = enum.nextElement().toString();
}
x++;
}
enum = FileSystemRegistry.listRoots();
fileList.set((roots[2] != null) ? roots : new String[]{"system/", "SDCard/", "store/"});
}
return fileList;
}
Try this code.
I'm new to Birt.
I'm trying to pass the connection to the report from my java application, but I get an error:
The following items have errors:
ReportDesign (id = 1):
+ There are errors evaluating script "importPackage(Packages.it.lfiammetta.birt); var conn = new

A BIRT exception occurred. See next exception for more information.
Error evaluating Javascript expression. Script engine error:

Script source:
/report/data-sources/oda-data-source[#id="43"]/method[#name="beforeOpen"],
line: 0, text:
__bm_beforeOpen(). (Element ID:1)
This is my java code that creates and launches report:
package it.lfiammetta.birt;
public class ReportRenderer {
public void executeReport() {
code...
Map<String, Object> appContext = task.getAppContext();
appContext.put("OdaJDBCDriverPassInConnection", myConnection);
appContext.put("OdaJDBCDriverPassInConnectionCloseAfterUse", false);
task.setAppContext(appContext);
task.run();
code...
}
}
This is the code I wrote in the script 'beforeOpen' the datasource:
importPackage(Packages.it.lfiammetta.birt);
var conn = new ReportRenderer();
reportContext.getAppContext().put("OdaJDBCDriverPassInConnection", conn);
I set the classpath.
Birt version I'm using is 4.2.1.
Thanks in advance for your help and I apologize for my English.
I'm doing that from Java code (IJDBCParameters - actually parameters for JDBC connections, I'm looking connection by name - OdaDataSourceHandle.getName()):
#SuppressWarnings("rawtypes")
private static void substituteJDBCConnections(IReportRunnable pReportRunnable) {
final Map<String, IJDBCParameters> jdbcConnections = reportParameters.getJdbcConnections();
if (jdbcConnections != null ){
for (Iterator iter = pReportRunnable.getDesignHandle().getModuleHandle().getDataSources().iterator(); iter.hasNext();){
// http://wiki.eclipse.org/Java_-_Execute_Modified_Report_(BIRT)
Object element = iter.next();
if (element instanceof OdaDataSourceHandle){
OdaDataSourceHandle dsHandle = (OdaDataSourceHandle) element;
String key = dsHandle.getName();
if (key == null){
continue;
}
IJDBCParameters jdbcParams = jdbcConnections.get(key);
if (jdbcParams == null){
continue;
}
try {
dsHandle.setProperty( "odaDriverClass", jdbcParams.getDriverName());
dsHandle.setProperty( "odaURL", jdbcParams.getConnectionString());
dsHandle.setProperty( "odaUser", jdbcParams.getUserName());
dsHandle.setProperty( "odaPassword", jdbcParams.getPassword());
} catch (SemanticException e) {
throw new UncheckedException(e);
}
}
}
}
Probably you fixed your issue already, but maybe someone will be looking for this in the future. First of all 4.2.x versions had problems with passed connections. I did not observed the same errors in 4.4.2.
Other thing, I do not get why you are trying to pass ReportRenderer as a connection in lines:
var conn = new ReportRenderer();
reportContext.getAppContext().put("OdaJDBCDriverPassInConnection", conn);
The passed object in here should be a java.sql.Connection object.
Therefore,
Map<String, Object> appContext = task.getAppContext();
appContext.put("OdaJDBCDriverPassInConnection", myConnection);
appContext.put("OdaJDBCDriverPassInConnectionCloseAfterUse", false);
task.setAppContext(appContext);
looks correct as long as myConnection is an implementation of java.sql.Connection
