Error in export to excel in oracle forms11g

I am using oracle forms 11g,weblogic 10.3.6 and java 1.7
I have tested webutil_demo, that worked successfully.
After that, I have implement a oracle form for export to excel functionality using webutil.
This form worked fine on server machine.
but other than server machine it gives an following Error:
oracle.forms.webutil.ole.OleFunctions bean not found.
CLIENT_OLE2.create_obj will not work
Note : on server machine, webutil_demo also worked fine.
I dont understand why this error.So please help me for solve this problem.

This error occurs when you have not imported webutil.pll and webutil.olb(do import "WEBUTILCONFIG" parameter and "WEBUTIL" Object group, webutil.pll and webutil.olb are available in Oracle installation directory say "C:\Oracle\Middleware\\forms") on your form.
If you dont want OLE functionality on your form, in that case import the object group of the name "WEBUTIL_NO_OLE".

Problems with jCifs authentication on oracle RDMS embedded jvm

I'm using jCifs 1.3.17 to connect and list files on remote windows share.
Everything works fine on my local JRE(5,6,7), but the same code executed on oracle 11g database (11.2.0.3.0) crashes with following stack:
jcifs.smb.SmbAuthException: Logon failure: unknown user name or bad
password. at
jcifs.smb.SmbTransport.checkStatus(SmbTransport.java:546) at
jcifs.smb.SmbTransport.send(SmbTransport.java) at

jcifs.smb.SmbFile.exists(SmbFile.java) at
pl.openlife.CifsConnect.listCIFSFiles(CifsConnect.java:49)
I found out, that user password lenght might cause the problem:
1. Windows env jdk1.5.0_22 -> works with long passwords
2. Oracle linux, RDMS embeded JVM -> works with short password only (8 characters)
3. Oracle linux, RDMS embeded JVM -> long password fails with error shown above.
Sample code:
NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication(domain,
username,
password);
SmbFile dir = new SmbFile(path,auth);
if(!dir.exists()){
// ABOVE CHECK FAILS
}
I heard somewhere about problems with oracle embedded jvm and bugs in JCE, but this shouldn't be the case, as jcifs have its own implementation of algorithms such as RC4 or DES. Does anyone have a clue what can be the case? Is there a way to walk this around?

Unfortunately I didn't find any answer to the issue mentioned above.
As a walkaround, I have used older version of jcifs (jcifs-1.2.25), which seems to work properly with oracle db embedded jvm.
UPDATE:
I have imported jcifs lib again (1.3.17) and it is working like a charm. I ended up with conclusion, that the java library was not imported properly. Reimport (loadjava) with option "-force" and manual compilation of invalid objects solves the problem always, but (I cant't figure why) in my case it must be loaded in following order :
1. Load my program lib (will cause errors)
2. Load jcifs lib with force option
3. compile and resolve
It seems that oracle jvm is unpredictable :)

Working with Php-Java Bridge

I am having trouble setting up the Php-Java Bridge setup properly.
I will explain what I have done.
My site is in pure php
For our payment transaction process we need to set up a php-java bridge
I followed this link to setup the bridge PHP-JAVA BRIDGE INSTALATION.
Here I learned that I need to have a private jvm to install the bridge.
So 1st i installed apache-tomcat-6.0.14 in Private JVM using my c-panel. After instalation it asked me to Map a domain to private JVM. So I mapped my domain example.com (which is the only option available) to it.
Then it asked to enable a traffic redirection from Apache web server to my Java application server (there was a check box and i clicked it)
Finally it asked me to deploy the WAR File (JavaBridge.WAR was my file) and everthing seems fine
Now when i go to http://example.com/JavaBridge/ I could see the javabridge examples and it works fine.
SO FAR SO GOOD
Now my problem starts here when I try to access a java class file from php. A sample test.php is what I create and put the following code into it.
<?php
require_once("http://example.com:portnumber/JavaBridge/java/Java.inc");
$System = java("java.lang.System");
echo $System->getProperties(); //This Part echo's correctly and shows the data so it means i can access Java.inc Correctly
$path_e24class = getcwd(). '/e24PaymentPipe.class'; //This part fails both test.php and java class file e24PaymentPipe.class are in the same directory in publich_html folder
java_require($path_e24class);
$pipe = new Java("e24PaymentPipe");
$pipe->setAction("1");
?>
My site contents reside in the public_html folder and the WAR file are deployed in private jvm.
These are the error message am getting.
1) Warning: java_require() not supported anymore. Please use tomcat or jee hot deployment instead
Fatal error: Uncaught [[o:Exception]:"java.lang.Exception: CreateInstance failed: new e24PaymentPipe. Cause: java.lang.ClassNotFoundException: e24PaymentPipe VM: 1.6.0_22#http://java.sun.com/" at: #-10

Finally I don't know much about the java. So am stuck here not knowing what to do.

Here is a great step by step tutorial you can follow, which shows everything required! It is a little old (2007) but helped me a while ago.
There is also another option. You can install Apache Tomcat and deploy your war there. You can have even multiple tomcat instances simultaneously with your httpd running at the same time on the same machine, as long as you respect the port settings. You can even front them with Apache httpd.

you can try this:
package your code to jar, and copy it to java.ext.dirs which you can found in JavaBridge.log
copy the related class libraries to java.ext.dirs
restart the service of JavaBridge
good luck!
<?php require_once("JavaBridge/java/Java.inc");
try {
$hd = new java("hdfs.HDFS");
$hd->get("hdfs://master:9000/user/hadoop/test-in/logo_cn.png", "/home/hadoop/1.png");
} catch (JavaException $ex) { echo "An exception occured: "; echo $ex; echo "<br>\n";}
?>

You can use this php implementation on github that works with php 5.3.
See credits on the git readme for more information.

You can try this; put the JavaBridge.jar in tomcat's lib folder e.g. apache-tomcat-7.0.12/lib.
Restart tomcat server and then,
$pipe = new java("com.aciworldwide.commerce.gateway.plugins.e24PaymentPipe");
$pipe->setAction("1");
This way I created the php version of the object.

Why don't you put the e24PaymentPipe class in your Java application's classpath and skip the two lines below:
// $path_e24class = getcwd(). '/e24PaymentPipe.class';
// java_require($path_e24class);
$pipe = new java("fully.qualified.classpath.e24PaymentPipe");
You are mixing PHP side and Java side operations. in theory the java_require (which is deprecated) was designed to work on the Java side. You are specifying a PHP side path.

You can save yourself a lot of grief by using a pure PHP implementation of the e24PaymentPipe library.
Disclaimer
The link is to my github repo of the library, but I did not write it. See the readme in for original credits.

Trying to install Sean Corfield's scripting for ColdFusion project, getting class not found errors

Hi I'm trying to install this tool 'Sean Corfield's scripting for ColdFusion project.' on my server - problem is I am getting "Class not found: com.caucho.quercus.script.QuercusScriptEngineFactory " errors, I have java 1.6 installed.... I'm not sure how where to get these extra classes ... any help?
[opensuse 11 system, CF8 java 1.6]
-thanks
-sean

Did you follow the installation instructions for the cfphp, as per the "example.cfm" page:
Installation:
1. Copy lib/quercus.jar and lib/resin-util.jar to WEB-INF/cfusion/lib/
(multiserver) or coldfusion8/lib (standalone)
2. Restart ColdFusion 8.
3. Optionally copy customtags/php.cfm into your custom tags path.
The important thing is that the quercus.jar is accessible to the JVM. Your error message indicates that the JVM can't find the jar.

Windows Java thread affinity with OpenHFT AffinityLock

I'm trying to optimize an application by binding its threads to different cores. To begin with, I would like to bind the entire application to a single core using the Affinity-3.0.6 package from OpenHFT.
So far I've had no luck. At first I imported the package and tried the command
AffinityLock al = AffinityLock.acquireCore();
was warned about not having JNA access, so I downloaded the jna-4.2.2 package and imported it as well.
After the second import, the same command gives the following error:
WARN Affinity - Windows JNA-based affinity not usable because it
failed to load! Reason: java.lang.NoClassDefFoundError:
com/sun/jna/platform/win32/WinDef$DWORD
and the execution is not bound to the single core.
I'm blindly trying to give the software what it wants without understanding what it needs.

i suspect youve added jna.jar, but not jna-platform.jar to your project, and the class that fails to load ispart of platform.
see docs and download links here.
