Sometimes I stop using my application for 10 minutes or more, and when I am back and start using it, it stalls and a debug message "NO CONNECTION TO DATABASE" appears in the Tomcat window. Why is that so ? Do I need some keep-alive messages ? If yes how can they be implemented ?

What is the meaning/function of the following declaration of getInitData method ? There is no body whatsoever, so what does getInitData actually do (obviously it is not inherited)? import java.util.Vector; import javax.servlet.http.*; public interface DataSelectionServInterface { public...

symantec.itools.awt.shape.HorizontalLine horizontalLine1 = new symantec.itools.awt.shape.HorizontalLine(); This line of Java code produces the error below. Oddly enough, when I comment the line out or try to debug inserting a few printlns it still reports the error in the very SAME line (392)...

When loading an applet, using Tomcat, I receive the error above. The jar containing the mentioned class and many other symantec classes is available in any possible directory and of course %CATALINA_HOME%\common\lib and is in the CLASSPATH. How can I fix the problem ...

My program requires the above package, which seems does not come with JDK. I have on my box only javax.servlet which seems not to contain what is needed. Where can I download javax.servlet.http from or can someone send it to me ? Thanks

Is it possible to observe the class hierarchy for a package in Jbuilder? If not, how can the main class be determined in a large package (of more than 50 files? Why "make project" and "build project" in jbuilder do not build all the files? Would you suggest some other Java IDE freeware that...

My prog has 2 vertical panels, they both appear when appletviewer is used, but with browser, the panel1 when it has many entries, it doesn't show up: GridBagLayout gridbag = new GridBagLayout(); GridBagConstraints constraints = new GridBagConstraints(); constraints.fill =...

My applet shows a name list that can have from 5 to 100 entries. I would like that it streches as needed, possibly having the scrolling bar when there are many entries. On the contrary, at the moment I depend on HEIGHT in my .html file, which is often too small or too big, and obviously before...

You'll recognise my ignorance about www applications, but I need urgent help. The java program below connects to oracle and retrievs the data. Yet, same piece of code within an applet cannot connect to the same db. Instead it receives the access denied (java.net.SocketPermission demo resolve)...
