Configuring JBuilder JDK's

Question

Hello again,
Well my CLASSPATH is now perfectly set and I can Compile my
code of MySql in Java 1.4.1 but now the problem is with my JBuilder
I changed the configuration of my project from the JDK from 1.3 the
default JBuilder JDK to the Java 1.4.1 but when I make my project it
gives me the following error
Warning #: 910 : cannot check class java.awt.event.ItemEvent; class file has wrong version 48.0; assuming package java.awt.event is stable; use of -nomakestable is recommended
Warning #: 910 : cannot check class gsales.SalesFrm$1; problem with import: class file has wrong version 48.0; assuming package gsales is stable; use of -nomakestable is recommended
What's the problem?

Answer 1

I tried to compile my project with the command line Java tools but ended up in the following errors
SalesFrm.java:79: cannot resolve symbol
symbol  : class Login_Dialog
location: class gsales.SalesFrm
   Login_Dialog login = new Login_Dialog();
   ^
SalesFrm.java:79: cannot resolve symbol
symbol  : class Login_Dialog
location: class gsales.SalesFrm
   Login_Dialog login = new Login_Dialog();
                            ^
Note: SalesFrm.java uses or overrides a deprecated API.
Note: Recompile with -deprecation for details.
2 errorsThese are the two classes:
