Exception Messages When Running Applets

[Raechael]

When I go to run my applet in applet viewer in visual cafe, anytime I am passing runtime parameters I get the following message.<br><br>warning: running 1.1 version of SystemEventQueueUtilities<br><br>java.lang.NumberFormatException: null<br><br>&nbsp;&nbsp;&nbsp;&nbsp;at java.lang.Integer.parseInt(Integer.java:377)<br><br>&nbsp;&nbsp;&nbsp;&nbsp;at java.lang.Integer.parseInt(Integer.java:458)<br><br>&nbsp;&nbsp;&nbsp;&nbsp;at BtnMaker.init(BtnMaker.java:25)<br><br>&nbsp;&nbsp;&nbsp;&nbsp;at sun.applet.AppletPanel.run(AppletPanel.java:333)<br><br>&nbsp;&nbsp;&nbsp;&nbsp;at java.lang.Thread.run(Thread.java:479)<br><br>Does anyone know what is going on here.&nbsp;&nbsp;I can email you the code.&nbsp;&nbsp;Whats funny is I can see that the parameters are being passed correctly because they are working on the form designer.&nbsp;&nbsp;Any help or clue would be greatly appreciated.<br><br>Email me at <A HREF="mailto:raechael@snet.net">raechael@snet.net</A><br><br>

hi,<br><br>maybe the there was a typo in the parameter name , basically the exception means that the String parameter that you are trying to parse is null.<br><br>String s = null ; <br>Integer.parseInt(s); // will give this exception<br><br>Try verifying the parameter names that you are passing in to the applet via the html &lt;PARAM&gt; tag.<br><br>bye<br><br>venkatesh<br>

I think you are basically trying to modify this string before it is initailized.&nbsp;&nbsp;Make sure that before you use this string or int you assign it a value.&nbsp;&nbsp;It would probably be best to put it in the init() method since that is called once one the applets loading.<br><br>hope this helps<br><br>ackka <p>moses<br><a href=mailto:tmoses@iname.com>tmoses@iname.com</a><br><a href=
