Tag Archives: Forms Not Launching

load: class oracle/apps/fnd/formsClient/FormsLauncher.class not found

Problem:

After installing fresh Release 12 instance (12.1.3), attempted to log on to application from client PC (Windows XPSP3). Was able to log on to R12, but forms could not be launched. The following message was displayed on the Java console:

load: class oracle/apps/fnd/formsClient/FormsLauncher.class not found.
java.lang.ClassNotFoundException: oracle.apps.fnd.formsClient.FormsLauncher.class
	at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source)
	at sun.plugin2.applet.Plugin2ClassLoader.loadClass0(Unknown Source)
	at sun.plugin2.applet.Plugin2ClassLoader.loadClass(Unknown Source)
	at sun.plugin2.applet.Plugin2ClassLoader.loadClass(Unknown Source)
	at java.lang.ClassLoader.loadClass(Unknown Source)
	at sun.plugin2.applet.Plugin2ClassLoader.loadCode(Unknown Source)
	at sun.plugin2.applet.Plugin2Manager.createApplet(Unknown Source)
	at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source)
	at java.lang.Thread.run(Unknown Source)
Exception: java.lang.ClassNotFoundException: oracle.apps.fnd.formsClient.FormsLauncher.class

However, other client machines (Windows 7) were able to log on and launch the forms.

Solution:

After enabling logging (Control Panel > Java > Advanced tab > Debugging, check all options), the ‘java.net.SocketException: Connection reset’ error was seen in the Java console. This indicated a network issue rather than a Java or browser issue. The EBS server (192.168.63.49) was on a different network from the client PCs (200.65.1.x). Therefore, a network route was added to keep the connection alive:

route add 192.168.63.0 mask 255.255.255.0 200.65.1.1 -p

FRM-92050: Failed to connect to the Server: /forms/lservlet: -1

Problem:

After installing E-Business Suite R12.1.3 on Windows Server 2003 Standard Edition, logged into R12 on the server and launched forms.

The following error appeared:

FRM-92050: Failed to connect to the Server: /forms/lservlet: -1

Solution:

The security settings on the Internet Explorer browser on Windows Server 2003 is set higher by default.

Added the name of the server to the Local Intranet group in IE’s security settings.

Reset Local Intranet security level to Medium-Low.

Load: Class Oracle/Apps/Fnd/Formsclient/ Formslauncher.Class Not Found.

Problem: When accessing any menu that launches core forms, get this error:

load: class oracle/apps/fnd/formsClient/FormsLauncher.class not found

Solution: Check the proxy server settings in the browser and ensure that addresses to bypass are correct.

Use the ‘hostname*’ format in the proxy server settings.

From Metalink article Doc ID:  Note:291698 (Subject: FormsLauncher.class Not Found Error When Attempting to Access Forms in Applications)

Steps for resolution:

  1. Launch a browser window.
  2. Go to Connection Settings for the Browser
  3. Select the Proxy exception list, the list of sites you have specified, for which no proxy is required
  4. Verify / validate all entries in this list.
  5. For e.g., you will need to add an entry like *.oracle.com instead of oracle.com to exclude all sites having oracle.com in the domain name
  6. Save the changes.
  7. Login and access the Applications forms in a new browser window.
