Oracle.forms.engine.Main not found.java.lang.ClassNotFoundException error

Hi Members,
I am getting the oracle.forms.engine.Main not found.java.lang.ClassNotFoundException error when trying to access Oracle forms using APEX 2.2.1 and SSO.
load:class.oracle.forms.engine.Main not found
The forms have been compiled, forms path setup properly and the setup required to run forms seems to be right. Jinitiator has also been installed.
I have searched the forums and tried everything. I have checked jinitiator settings, cleared cache and even reinstalled it. Do you have any experience with this error? Appreciate any answers. Thanks.
Ravi.

Dear Friends,
I was also facing the same problem. to solve this, i have uninstalled Oracle Jinitiator. Cleared all the temporary internet files & cookies. Then while running the form, when it asks to install JInitiator, i have specified a different path for jinitiator, For Example, By default it asks for C:\programfiles, i have changed it to c:\manish directory.
This has solved my problem. Probably this also help you.

Error oracle.forms.engine.Main not found.java.lang.ClassNotFoundException

Hi all,
I tried to update oracle_logo.gif in forms jar which is in f90all_jinit jar. I placed my icon in forms\oracle\forms\icons and renamed it as oracle_logo.gif while removing the existing one. Then I did jar the forms and placed that in f90all_jinit and again did jar f90all_jinit. Then, I placed this in ORACLE-HOME/forms90/java. When I tried to run the form...the form could not open and the java console shows this..
Loading http://<MACHINE_NAME>:8888/forms90/java/f90all_jinit.jar from JAR cache
load: class oracle.forms.engine.Main not found.java.lang.ClassNotFoundException: java.io.IOException: open HTTP connection failed. at sun.applet.AppletClassLoader.getBytes(Unknown Source) at sun.applet.AppletClassLoader.access$100(Unknown Source) at sun.applet.AppletClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at sun.applet.AppletClassLoader.findClass(Unknown Source) at sun.plugin.security.PluginClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.applet.AppletClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.applet.AppletClassLoader.loadCode(Unknown Source) at sun.applet.AppletPanel.createApplet(Unknown Source) at sun.plugin.AppletViewer.createApplet(Unknown Source) at sun.applet.AppletPanel.runLoader(Unknown Source) at sun.applet.AppletPanel.run(Unknown Source) at java.lang.Thread.run(Unknown Source)
Can anyone guide me on how to get rid of this error ? Strange thing is that I've removed that f90all_jinit.jar and placed back the existing one (I took backup). But still it's showing the same error and not opening the form. I could and can not do anything without this error corrected.
Please suggest me as soon as possible...
thank you

Load: class oracle.forms.engine.Main not found Stuck at loading Java Applet

Hi there
I have recently installed App Server 10.1.2.0 on a new machine.
Copied all my forms to an appropriate directory. Set up formsweb.cfg to allow them to run and have attempted to run them.
Unfortunately I get stuck at the Loading Java Applet screen, and in the status bar at the bottom it says :
load: class oracle.forms.engine.Main not found
I have taken a look at the Java Console, and the 2 things that jump out at me are that it appears to be looking for a forms90 directory, which seems odd since I am using App Server 10.1.2.0.2 and Forms Builder 10.1.2.0.2 meaning it should be looking in a forms directory not forms90 directory shouldnt it ?
And also, it mentions class with no proxy, so on looking around the forums it has been suggested that put the proxy details into jinitiator, which I have done, but this has made no difference either.
Can anyone suggest anything else please ?
Java Console log follows.
Thanks a lot

In my case, on my machine, the codebase virtual directory name is defined as forms60java and is mapped to the Forms_Home\Forms60\Java directory, which is where the f60allxxx.jar files are stored.
Alias /forms60java/ "D:\Oracle\806\FORMS60\java/"
Look out for the 6iServer.conf file on the Oracle9iAs installation of Forms. In this file you see the value used in your configuration. Open the formsweb.cfg file (assuming you are using the Forms Servlet) in the forms60/server directory and search for the "codebase" parameter. The value should be the relative path mapping in the 6iServer.conf file.
You can test if the codebase value works in that you copy an image to the forms60/java directory and call it by
http:// ..../<forms_mapping>/gifname

Any ideas/suggestions?

Java.lang.ClassNotFoundException: oracle.forms.engine.Main

I got this error when opening my forms, in java console, it says the frmall.jar file cannot be downloaded.
I tried to get access the file with http://192.168.3.44:9001/forms/java/frmall.jar , it displays 404 page not found.
I think the virtual path defined in forms.conf is not working at all. Because I tried to put a html file under each of the directory, none of them are accessible.

Jre hangs/freeze at digital signature dialog (oracle.forms.engine.Main)

hi,
we are using webforms (application server 11).
when a client starts up a form in the browser the dialog for accepting the digital signature (oracle.forms.engine.Main) appears. in this dialog wether a button can be klicked nor the checkbox (always trust...) can be checked. still this dialog can be moved.
what's the reason for that?
we tried different jre versions (1.6 u12 - u20) and also patch 9553040 (jrefb-6u20-rev-b05-windows-i586.exe) doesn't work - the same problem appears.
regards,
matthias

It does!
I [read this paper|http://forms.pjc.bean.over-blog.com/ext/http://www.oracle.com/technology/products/forms/pdf/SigningJint13.pdf] before, years ago the first time. It's from *2002* and refers to JInitiator. And I read this paper again. But I stopped around page 13, reading
+"PROBLEMS WITH MULTIPLE SIGNING IDENTITIES+
+There is currently a restriction within Oracle9i Forms. If a Forms application is+
+started within JInitiator or the Sun Java Plug-in, which uses code signed with+
+multiple certificates ... This restriction will be lifted in a later release of Forms ...."+
Not one of my best ideas. Notice, Sun Plug-in is mentioned and +8 years+ might not be enough, obviously.
Reason behind the "re-appearance" of the problem with forms 11g is that the forms jars (including webutil) are now signed with an VeriSign certificate what was not the case with 10g. Downloading jacob.jar by your own, you get an unsigned jar file. Signing this, as you were used in 10g leads to the second signing identity and the freezing problem.
But let's see how we could solve the problem, for the moment, perhaps for the next 8 years. We
. took solution path 2 out of the aove cited paper (Register Your Custom Signing Certificate Separately).
. rename jacob.jar to jy_jacob.jar (we do not want to interfere with other forms application of other companies also using webutil)
. add the registration applet code as described in the paper to jy_jacob.jar
. sign jy_jacob.jar.
. [to be on the save side we repeated these steps for all our jar files, necessary for the application]
. rename webutiljpi.htm to webutiljpijy.htm
. modify webutiljpijy.htm by adding applet registration section before webutil registration. This reads like

<OBJECT classid="%jpi_classid%"
codebase="%jpi_codebase%"
WIDTH="0"
HEIGHT="0"
HSPACE="0"
VSPACE="0">
<PARAM NAME="TYPE" VALUE="%jpi_mimetype%">
<PARAM NAME="CODEBASE" VALUE="%codebase%">
<PARAM NAME="CODE" VALUE="com.joynit.forms.applet.RegisterCertificateApplet">
<PARAM NAME="ARCHIVE" VALUE="%archive%,%webUtilArchive%" >
<COMMENT>
<EMBED SRC="" PLUGINSPAGE="%jpi_download_page%"
TYPE="%jpi_mimetype%"
java_codebase="%codebase%"
java_code="com.joynit.forms.applet.RegisterCertificateApplet"
java_archive="%archive%,%webUtilArchive%"
WIDTH="1"
HEIGHT="1"
HSPACE="0"
VSPACE="0"
>
<NOEMBED>
</COMMENT>
</NOEMBED></EMBED>
</OBJECT>

. modify formsweb.cfg so that webutiljpijy.htm and jy_jacob.jar are used (original settings as comments below)
baseHTMLjpi=webutiljpijy.htm
#baseHTMLjpi=webutiljpi.htm
archive=frmall.jar,iText-5.0.3.jar,vzg_grafik.jar,vzg_images.jar,vzg_netz.jar,jy_pdfutil.jar
#archive=frmall.jar
WebUtilArchive=frmwebutil.jar,jy_jacob.jar
#WebUtilArchive=frmwebutil.jar,jacob.jar
And then, after flushing the jar cache, success! No freezing. It was possible to confirm the certifcates and to start the application.
Thnx to Mia Urman and the oracle forms communitiy on [http://oracleformsinfo.wordpress.com/] , who gave me the tip... There is another, easier solution.
Never set one of the original oracle jar-Files on pole position (1st position) in one auf the archive parameters. This leads to hanging.
Put one of your self-signed jar-Files in front and let the oracle jars follow. The forms application will start properly.
It work with 3 different signing authorities, also. What makes hope for 4, and so on.

I'm getting the java.lang.ClassNotFoundException error when running the WSCOMPILE utility. Here is my config.xml:
<?xml version="1.0" encoding="UTF-8"?>
<configuration xmlns="http://java.sun.com/xml/ns/jax-rpc/ri/config">
<service name="HelloService"
targetNamespace="http://echoservice.org/wsdl"
typeNamespace="http://hello.chap12.jboss.org"
packageName="mypackage">
<interface name="mypackage.HelloWorldWebServiceSEI"/>
</service>
</configuration>
and here's my interface:
package mypackage;
import java.rmi.RemoteException;
public interface HelloWorldWebServiceSEI extends java.rmi.Remote
public String sayhello(String Name) throws RemoteException;
I'm running the command:
wscompile -define -mapping mypackage/mapping.xml -d mypackage -nd mypackage -classpath mypackage config.xmlBut keep getting this error. Can someone help?
Many thanks,
Jon

Here is my information....I think I have included everything needed.

Could not find the main class. & java.lang.NoClassDefFound error:

sir / madam
I am facing problems with j2ksdk1.4.0 beta instalation on my windows 2000 advance server.
while installing pops up a message saying could not find the main class.
while using java or javac it says
Exception in thread main
java.lang.NoClassDefFound error:
com/sun/tools/javac/main
even when double clicking java plugin from the control panel
I get the Java virtual machine launcher saying could not find the main class.
I don't have any other java sdk installed.
And i have my environment variables (classpath, path and java_home) set correctly.
this same j2sdk1.4.0 version is installed in the windows 98 system and it's working fine.
Kindly do help me to solve this problem.
eagerly awaiting for your response.
Thanking you

you must check with the classpath
please see that you have not repeated %classpath%
at the end of the class path like you do in win98.
similiarly with %path%
in win2000 it is automatically taken care off.

Lookup form standalone client fails with java.lang.ClassNotFoundException

Hi,
I have an issue under Weblogic 11g when a standalone client tries to lookup for an ejb deployed in an ear.
The ear is correclty deployed without any errors and the EJB is correctly defined in the jndi tree (i see it using the jndi browser through the weblogic console).
When my client tries to lookup the EJB using its correct JNDI name, the client receives the following exception :

Yes it is in my classpath. You can take a look at my command line generated by my IDE :

Java.lang.ClassNotFoundException: error's

Hi i tried connecting to a digi chat site for 3 days now and all it has been giving me is errors (for example the one below):
java.lang.ClassNotFoundException: com.diginet.digichat.client.DigiChatApplet
Java will not load up the applet.
But i noticed one thing, when i used an Anonymizer Proxy software which enables you to surf the web hiding your real ip or given a fake one....(link below):
http://www.anonymizer.com/consumer/products/anonymous_surfing/
When i used this software it loaded the digi chat applet up fine but, then had connection issues connecting to digi chat room which in return an error applet window popped up saying :
DigiChat could not connect to the specified host.
Please verify that the DigiChat Server is running and
that you are using the correct host name.
java.net.ConnectException: Connection timed out:
connect
Note: I have 3 computers in my house hold and all of them access the same isp and all three have the same problem while connecting to this certain host.
If anyone has any ideas or regards to this malfunction or error please contact me.
Thank you so much!!!

you have to download the jdbc drivers for a perticular database. These are nothing but jar files. You have to then add these jar files to yor project library. An your problem will be solved
