Hello There, I have been trying to get my java applet to working properly on my powerdnn host and was having a hard time with it. After conversing back and forth with their level1 and level 2 technitions tonight I finally got to the bottom of the problem and realized that in my specific case the cause had to do both with the hosting company and myself as their were many factors in this issue which weren't all factors in regards to host related tasks like setting up proper mimes but I wanted to share with you the letter I wrote to them about my solution as I thought it might help some folk here on creative magazine who might of run up against a wall when trying to implement java applets. --------------------------------------------- Hello There, I just wanted to let you know I finally cracked the case of the defunct java applet and what my investigation turned up was that there were multiple factors causing this not to work correctly for me and I thought I might list them here so in case someone else has an issue you may be able to look at it. 1. When creating the MIME for the java applet and jar file I failed to use correct extensions (i.e. .class and .jar) rather I interpreted extension as meaning the same as say label or how would you like the mime to be named opposed to what extension should be associated with perticular MIME Content. Thanks for creating the jar mime for me correctly by adding the .jar in the extension area that was what gave me the clue that my extension called javaapplet should have been called .class. 2. Apparently a signed JAR file has a rule that it can only be one directory deep from the root of your web application check out the following website for insight on this http://www.coderanch.com/t/259054/A...FoundError by attempting to put the class and jar files in what I considered the place where DNN would likely call the root of the application (i.e. /portals/0) was actually two folders deep from the real root (i.e. admin, desktopmodules, etc...) so hence broke the rule for signed jar extension and hence wouldn't work 3. While I did upload the class file that showed up in the code attribute of the applet tag apparently this compiled java code was calling for another class which I hadn't uploaded and I guess I just assumed when the java console at times gave me the message NoDefClass found instead of carefully reading the name of the .class file it was looking for I assumed it was looking for the one I had wired into the code attribute of the applet tag opposed to a class file that was being called from the compiled class that was wired into the applet tag. Once I fixed up issues with the mime on your server, uploaded all needed class files and assured all these files were only one directory deep from the root of the application all worked fine. By the way in order to do this I had to use the codebase attribute (which had to be an absolute link) to tell the applet tag that the jar and class files could be found in a folder one level deep from the root of the domain. the codebase tag would not allow me to use a relative link though. Now the only other hiccup I have to figure out (which isn't something you guys have to worry about) is how to get two submit buttons that initially came with this applet to post without using actual <form>> and </form> tags since this would be breaking the asp.net rules of form within a form. I know the javascript DOM is capable of allowing form components to post appropriately without the use of the FORM tag I just have to dig in and figure out how this could be done. Thanks ya'll for working with me on this though and hopefully this comment can be beneficial to all you level 1 and 2's out there if another customer like me runs against a wall in regards to these java applets in a DNN environment. Take Care, Bo --------------------------------------------------

Bo,

Thank you for this detailed posting. I too am attempting to get a java applet to work. Here is the structure as it is called in a simple .html page:

</style>





<script language="javascript" type="text/javascript" src="scripts/mycustomapp.js"></script> <br /> <script language="javascript" type="text/javascript"> <br /> //<![CDATA[ <br /> var applet = new MYApplet("applet", "applet/mycustomapp.isms", getCustomDefaultResources("applet/resources"), ""); <br /> //]]> <br /> </script> <br /> </html> <br /> <br /> My questions are: <br /> - where/how did you place your statements in your DNN page (in an ascx page?) <br /> - how is this best to load? Putting in my aspx skin doesn't allow me to add statements outside of <body> tag but before the closing </html> tag. <br /> - is this the best way to proceed? <br /> - where did you place your java and support files (under your \Portal\nn\ folder?) <br /> <br /> Thanks for your help! <br /> <br /> - where did you place your java and support files (under your \Portal\nn\ folder?) <br /> <br /> Thanks for your help! <br />
