Oracle Forms application is not loading

Hello all,
We have an internal forms application deployed on Oracle Application Server 10.1.2.3
It was working fine till I applied an oracle patch 8374931 today.
After patch application our forms application refuses to load.
I get the following errors in the java console.

Kindly help me to short out the problem.

Amit.Try with down grade of Mozilla firefox. may be version 6 to 8. not 9/10.
Firefox with 9 and higher doesn't support JRE version 1.6.XX.
Hopes this helps

  • 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

  • Calling Java screens from Oracle Forms application

    I am working with a client that has a large Oracle forms application. Since rewriting the entire application in Java is not an option at this time, the strategic direction is that any new modules that are to be created for the application are to be done in Java and called from the Forms menu. The decision as to what tool to use to develop the Java modules is still under debate. What is the best (most seamless) way to do this...calling a Java screen from a Forms application? If anyone has any experience in this, or can direct me to some literature on it, it would be greatly appreciated. Thanks.

    This is a web app in Forms/Reports 10g R2 running off Oracle AS and an Oracle db. The challenge for us is that the direction is that any new enhancements (screens) are to be built using Java (in either ADF Faces or Swing, another point for debate later) and then called from the Forms app. The business client is only paying for the enhancement. They don't care about moving off Forms to Java, so any extra work on the part of IT to do this, has to be fairly minimal and doable within the project budget. The movement to Java is an IT direction. Is there a way to do this without having to build a java framework for the entire Forms application (which I assume would take some time and involve retesting the entire app)?

  • 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.

    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

  • Integrate a Oracle Forms Application in SAP Enterprise Portal

    Hello togheter,
    i would like to integrate a Oracle Froms Application in our SAP Enterprise Portal. We use Oracle Froms AS 10g v10.0.2. I read that oracle forms supports single-sign-on, but i don't understand exactly how does it works? What steps i need to do? Has anybody experience in this topic? Supports oracle forms application SAP Logon Tickets?
    Many thanks in advance and greetz,

    Hello, thanks for your answer.
    I can't use the first option from you, because of the necessity to use SAP Logon Tickets.
    If i understand everthing right, it is possible to implemant the SAP-Logon-Ticket-Libary in the integrated application. By Oracle Forms is this not possible, because it is a framework application. The authentification to the Oracle Forms application is transferred over the Oracle Application Server. It is also no possiblity to implement the libary in the application server.
    Today i talked to the Oracle Support and they said that one solution is to use the Oracle Access Management as Middle-Software between SAP EP and Oracle Application Server.
    What do you think about this solution? It is really not possbile to integrate Oracle forms in SAP EP with SAP-Logon-Ticket without an extra software?
    Thanks in advance,

    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

    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.

  • Integrate a Oracle Forms Application in SAP EP

    Hello,
    i would like to integrate a oracle forms web application on my SAP Portal. But i have a problem with the single-sign on. What steps i need to do, to integrate the oracle application? Has anybody experience in this topic? Supports Oracle Forms SAP Logon Ticket?
    Many thanks in advance,

    Hello, thanks for your answer.
    I can't use the first option from you, because of the necessity to use SAP Logon Tickets.
    If i understand everthing right, it is possible to implemant the SAP-Logon-Ticket-Libary in the integrated application. By Oracle Forms is this not possible, because it is a framework application. The authentification to the Oracle Forms application is transferred over the Oracle Application Server. It is also no possiblity to implement the libary in the application server.
    Today i talked to the Oracle Support and they said that one solution is to use the Oracle Access Management as Middle-Software between SAP EP and Oracle Application Server.
    What do you think about this solution? It is really not possbile to integrate Oracle forms in SAP EP with SAP-Logon-Ticket without an extra software?
    Thanks in advance,

    I don't believe that Forms will be certified on WLS until 11g based on a ppt I saw at Oracle Open World. However, you'll need to get confirmation on that from someone with Forms knowledge. Their forum is here:
