(This message follows another message of Jurge Hallez.)
Hello,
Thanks for the replies. Hello to the one in Antwerp ! I live in Merksem.
The problem is that I don't know much about java and jsp programming, and that my program should be ready this thursday.
I am almost sure that the code is 99 % right. THe only question I have is whether the method to count for the average of the salaries is correct. In de code, this method is called bereken() (translated into english calculate()). The error I get is in the deloytool of the SDK J2EE 1.4. When I try to save the file, it says sax error, premature end of file. Then the application closes and I can not reopen the application.
Another error I got with another aplication is the following. I get this errot when I try to run the appliaction in the browser.
HTTP Status 500 -

SAX errors in deployment are errors related to your deployment descriptors, not your Java source files (though it is possible that the deployment descriptor is correct but the Java file doesn't properly reflect it).

[Bear Bibeault]

jurgen, please do not open multiple topics for the same question. Rather continue the discussion in the same topic until resoultion. .
Because the issue is now being discussed in this topic, I have closed your first so that multiple redundant conversations do not take place.
thanks,

Jurgen, the solution for one of your errors is already given in this message
No Java compiler was found to compile the generated source for the JSP.
This can usually be solved by copying manually $JAVA_HOME/lib/tools.jar from the JDK
to the common/lib directory of the Tomcat server, followed by a Tomcat restart.
If using an alternate Java compiler, please check its installation and access path.
So check for the tools.jar file to see whether it is in the common/lib directory of Tomcat.
If you have other questions, you can send me a personal message using the button of the enveloppe. And you can send them in Dutch.
But remember : I can only look at your questions after working hours (say after 19OO). But I suppose that won't be too much of a problem since we're living in the same time zone.
