The Forms<\/a> functionality on Oracle E-Business Suite<\/a> is an integral part of an organization\u2019s ERP<\/a> Solution. In situations where Forms need to be accessed from a machine running Oracle Linux 6, the default browser Konqueror<\/a> does not support it.
\nThrough the course of this blog, I will attempt to resolve this issue by using the Firefox browser.<\/p>\n

Detection<\/h1>\n

A current release of the Firefox browser (version 58) has dropped NPAPI<\/a> support which disables Forms to detect the JRE version installed on the machine.
\nFirefox Extended Support Release<\/a> continues to offer plug-in support. End-users who need to use Forms-based content in EBS must run the Firefox Extended Support Release.
\nThe latest version of Firefox Extended Support Release (version 52) needs the GTK 3<\/a> library which is not supported on Oracle Linux 6 (by default) to circumvent this, Firefox Extended Support Release version 49 can be installed (which uses GTK library 2).
\nFor all Linux distributions, a tarball<\/a> is offered as a download link which can be found on the official Mozilla website.<\/p>\n

Solution<\/h1>\n

Extract the tarball into the ~<\/strong> directory of the root user.
\nOnce it has been extracted, launch Firefox by entering
\n.\/firefox<\/strong><\/p>\n

The next step is to enable the libnpjp2.so<\/strong><\/a> plugin that allows EBS Forms to use JRE from the browser.
\nThe Forms functionality also needs JDK version 1.8.0_102<\/a> (or above)
\nGet the required JDK version by downloading the rpm package from the Oracle Archives Page
\nOnce the JDK is in place, navigate to the directory
\n\/usr\/java\/jdk1.8.0_120\/jre\/lib\/amd64\/libnpjp2.so (FOR 64 Bit Version)
\nAnd ensure that the libnpjp2.so file exists in that location.<\/p>\n

Create a Symbolic Link<\/a><\/h2>\n

Create symbolic links in 3 directories<\/p>\n

cd \/usr\/lib64\/mozilla\/plugins<\/em>
\ncd \/usr\/lib64\/mozilla\/plugins-wrapped<\/em>
\ncd \/etc\/skel\/.mozilla\/plugins<\/em><\/p>\n

by using the command<\/p>\n

ln -s \/usr\/java\/jdk1.8.0_102\/jre\/lib\/amd64\/libnpjp2.so<\/em>
\nwhile in each of the directory<\/p>\n

Bounce Firefox to view changes when about: plugins<\/strong> is entered in the address bar<\/p>\n

Java(TM) Plug-in 1.8.0_102<\/em>
\nFilename: libnpjp2.so The next generation Java plug-in for Mozilla browsers.<\/em><\/p>\n

Configuring Java to allow self-signed certificates<\/h2>\n

When EBS Forms is being used in a development environment, it is essential to configure Java to accept self-signed certificates.
\nDue to the default security settings, Java blocks requests from domains that have self-signed certificates.<\/p>\n

To allow a local domain to access Java, a Site Exception<\/a> can be added, to do so, Java Control Panel needs to be started.
\nTo start the control center, navigate to the \/bin folder of the installed JRE version; in case of a default install it would be :<\/p>\n

\/usr\/java\/jre1.8.0_102\/bin<\/em><\/strong><\/p>\n

And launch the Control Panel by issuing the<\/p>\n

.\/ControlPanel<\/strong><\/p>\n

command.<\/p>\n

Click on the Add an Exception<\/strong> button at the bottom and the local domain on which the EBS application is running.
\nSave changes and bounce the server to notice the effects.<\/p>\n","protected":false},"excerpt":{"rendered":"
