FireFox, IE crash with Forms 10g, Replace Jinitiator with JRE

Oracle Jinitiator is no longer compatible with oracle forms services. By default, Oracle Forms services 10g uses Jinitiator 1.3.1.22 to run Forms applications. Jinitiator was compatible with Internet Explorer 6 and Firefox version 2.0. But latest internet explorer like IE 8 and 9 crash with Jinitiator. Similar behavior is seen with Firfox version 3.0 and later.

To resolve this problem, you must configure JRE to work with forms services 10g. It is really easy and requires only very little work. Forms services 10g are by default configured to run with JRE 1.4.2_06. To get this working, locate following lines in your FORMSWEB.CFG file,

# System parameter: default base HTML file

baseHTML=base.htm

# System parameter: base HTML file for use with JInitiator client

baseHTMLjinitiator=basejini.htm

# System parameter: base HTML file for use with Sun’s Java Plug-In

baseHTMLjpi=basejpi.htm

Make changes as shown in bold face below.

# System parameter: default base HTML file

baseHTML=basejpi.htm

# System parameter: base HTML file for use with JInitiator client

baseHTMLjinitiator=basejpi.htm

# System parameter: base HTML file for use with Sun’s Java Plug-In

baseHTMLjpi=basejpi.htm

Make sue that following parmaments in FORMSWEB.CFG are as mentioned below.

jpi_download_page=http://java.sun.com/products/archive/j2se/1.4.2_06/index.html

jpi_classid=clsid:CAFEEFAC-0014-0002-0006-ABCDEFFEDCBA

jpi_codebase=http://java.sun.com/products/plugin/autodl/jinstall-1_4_2-windows-i586.cab#Version=1,4,2,06

jpi_mimetype=application/x-java-applet;jpi-version=1.4.2_06

Now install J2RE version 1.4.2_06  from following URL,

http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-javase14-419411.html#j2re-1.4.2_06-oth-JPR

OR

you can also omit version no from following line,

jpi_mimetype=application/x-java-applet;jpi-version=1.4.2_06

after ommiting version, above line will look like following

jpi_mimetype=application/x-java-applet

Now you can use any latest JRE version. (Thanks to S Shamji  and JoeAStudent for thier comments related to version change )

Remove Jinitiator from you computer and restart OC4J instance. Now your Forms application 10g will use Sun’s Java plug-in instead of Jinitiator.

Update:

Looks like Firefox 12 does not work by omitting version no from formsweb.cfg. Instead you need to provide correct installed version.

For example, If you have jre 1.6.x installed in your system then edit following line as under.

jpi_mimetype=application/x-java-applet;jpi-version=1.6

The above line covers JRE 6 with all update levels.

If still facing problem then provide the exact version of  JRE with update level as under.

jpi_mimetype=application/x-java-applet;jpi-version=1.6.0_24

In “formsweb.cfg”,  jpi_classid indicates the version of JRE. “clsid:CAFEEFAC-0014-0002-0006-ABCDEFFEDCBA” indicates that 1.4.2_06 or any later version can be used.
