Applet and Java Plug-in

843807Dec 5 2002 — edited Dec 11 2002
I am using Java Plug-in with an applet.
The applet is invoked from the JSP page.
When I resize the container frame I want to resize the applet frame so I have a resize() function in the JSP which invokes the setSize() function in the applet on resize and on Load.

I am getting an error "Object does not support this property or method" when the resize() invokes the "document.ViewerApplet.setSize(w_newWidth,w_newHeight);"

What might be the reason?
Here is my JSP code:

<SCRIPT LANGUAGE="JavaScript">
function resize()
{
var w_newWidth,w_newHeight;
.....
document.ViewerApplet.setSize(w_newWidth,w_newHeight);
window.scroll(0,0);
}
window.onResize = resize;
window.onLoad = resize;
</SCRIPT>
<BODY onResize="resize()" onLoad="resize()">
....
<OBJECT classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
NAME = "ViewerApplet" WIDTH = 400 HEIGHT = 500 codebase="http://java.sun.com/products/plugin/1.3/jinstall-13-win32.cab#Version=1,3,0,0">
<PARAM NAME = CODEBASE VALUE = "." >
<PARAM NAME = CODE VALUE = "com.plx.ifo.client.gui.imageViewer.imgViewerApplet.class" >
<PARAM NAME = ARCHIVE VALUE = "Viewer.jar" >
<PARAM NAME="type" VALUE="application/x-java-applet;version=1.3">
<PARAM NAME="scriptable" VALUE="false">
<PARAM NAME = "pagecount" VALUE ="<%=strPageCount%>">
<PARAM NAME = "url" VALUE ="<%=strURL%>">
</OBJECT>
</BODY>

Read the documentation: https://python-oracledb.readthedocs.io/en/latest/user_guide/connection_handling.html#connecting-to-oracle-cloud-autonomous-databases
The default 'Thin' mode of python-oracledb you are using needs the wallet in PEM file format. This is a requirement of the Python libraries now being used, since Thin mode doesn't use the Oracle Client libraries (which use a .sso file). Recent wallet.zip files include a .pem file. If you don't have one, then re-download the wallet.zip file. Or you can convert the .p12 file in your wallet.zip to a .pem file using the utility script in the documentation.
Pass the directory (not including the filename) containing the wallet when you connect. You also need to specify the wallet password:
connection = oracledb.connect(user='northwind', password=pw, dsn='db21cpresent_medium',
config_dir="c:\the\dir\containing\the\tnsnames\file",
wallet_location=r"c:\the\dir\containing\the\pem\file", wallet_password=wpw,
)
Alternatively, enable 'Thick' mode and you won't need the above.
A third option is to use 1-way TLS. That is also in the documentation

Great thanks, Christopher!
It works with the specification of the three parameters (Windows 10) now:
connection = oracledb.connect(user='northwind', password=pw, dsn='db21cpresent_medium',
config_dir="c:\\my\\wallet\\dir",
wallet_location="c:\\my\\wallet\\dir",
wallet_password=wpw
)
In my wallet-dir there are the tnsname.ora and ewallet.pem files after unzipping of the wallet.zip file.
Ciao, Friedhold
