Release 10.1A: OpenEdge Development:
Java Open Clients

Supporting both browsers with the same page

To support both Internet Explorer and Navigator with the same Web page, include code like this:

<OBJECT CLASSID="CLSID:E79DA910-15D0-11d2-B591-00C04FD4A860"         CODEBASE="/cabs/o4glrt.cab#Version=9,0,1066,0"> <applet code="AppletTest.class" codebase="/cabs" name="AppletTest" width="320" height="240" archive="apptest.jar,o4glrt.jar"> <PARAM NAME=cabbase VALUE=/cabs/apptest.cab> </applet>

When using the code in this example, be aware of the following issues that arise for the difference browsers:

Navigator ignores and does not support the OBJECT tag and the cabbase PARAM.
Internet Explorer supports the OBJECT tag and the cabbase PARAM and looks for classes in the .cab file specified in the cabbase PARAM of the OBJECT tag before using the .jar files specified in the applet tag's archive attribute.
Internet Explorer does not support Netscape's code signing technology, as a result, any code found in .jar files is untrusted and limits the servers to which the browser can connect.
Navigator does not support .cab files and, as a result, it ignores the cabbase PARAM; therefore, you need to specify both .cab and .jar files.
