Converting Java applet into <object>

Question

I recently updated my Java to the most up to date version and this caused an applet that I work with to not run correctly. I have changed the security parameters for Java through the Control Panel to the lowest possible settings but my applet still does not run. Here is what my applet looked like:

<HTML>
 <BODY BGCOLOR="#003333">

 <p>
 <APPLET name=IpixViewer code=IpixViewer.class archive="IpixViewer.jar" width=450      height=450>
<PARAM NAME="url" VALUE="209_a_CHEM.ipx">
 </APPLET>
 </p>

 </BODY>
 </HTML>

I tried to use the HTML tag as a work around but this also is failing. Here is that code:

<HTML>
<body>
<p>
<object type="application/x-java-applet;version=1.6" name="IpixViewer" id="ipixviewer"  style="width:450px;height:450px" >
<param name="code" value="IpixViewer.class" >
<param name="archive" value="IpixViewer.jar" >
<param name="codebase" value="Z:\filepath\">
<param name="url" value="205_a_CHEM.ipx" >

</object>
</p>
</body>
</HTML>

I think the issue is when I try to pass the url parameter into the applet but I am not sure. Any help would be appreciated.

The parameter CODEBASE is used to add a path to the jar file, e.g.:

CODEBASE="./my_path_to_jar"

So to draw a complete picture, this is a working example:

<HTML>
  <HEAD></HEAD>
  <BODY>
    <APPLET NAME="IpixViewer"
            CODE="IpixViewer.class" 
            CODEBASE="."
            ARCHIVE="IpixViewer.jar" 
            WIDTH="320" HEIGH="240" >
    <PARAM NAME="URL" VALUE="image.ipx">
  </APPLET>
</BODY>
</HTML>

This HTML file (ipix.html), the jar file IpixViewer.jar and the image image.ipx are all placed in the same folder.

As it is not easily possible to start an applet from a local hard disk, I used a tool called HFS to access the website. For this just start the program, drop the files on it and type http://127.0.0.1/ipix.html.

If this doesn't help you can open a Java console in order to retrieve further information.

This is what my Java console shows: \Java version: 1.7.0_25 JVM version: 23.25-b01 JVM vendor: Oracle Corporation Java specification name: Java Platform API Specification Java specification vendor: Oracle Corporation Java specification version: 1.7 OS architecture: x86 OS name: Windows 7 OS version: 6.1 Browser: Mozilla/4.0 (Windows 7 6.1) Loading IPIX: 'null'...

Ok, I was slightly on a wrong track. Just made a small test and it worked quite well. Note that it is not possible to start from a folder directly.

In particular, the codebase parameter needs to be a URI, not a file path. Z:\filepath\⁠ is not a valid URI, but file:///Z:/filepath/ is. A URI always contains forward slashes, on every operating system.

Give the java deployment toolkit a try. It will work great and handles cross browser compatibility.
