downloaded sql developer and xe213 database, cant get it connect?

User_OLVNIJan 16 2022 — edited Jan 16 2022

hello, first time sql user here, i'm trying to practice some queries and was told to get familiar with the sql developer, i have the sql developer up and running, and installed 21c. they are both on the c drive using default installation settings.
right now i can't do anything as it won't connect to the database, is it because i didn't install the database in the correct directory? when i add a new connection, after input the same pw i made while installing the 21c express edition, and using sys for username, it cant connect and it failed testing.
also
No TNS entries found in {USER Home dir=C:\Users\kyle, ORACLE_HOME=C:\app\kyle\product\21c\dbhomeXE\network\admin}
under the TNS file load option

If you have to resort to GCJ, you are already on thin ice and should rethink your strategy. I'd say you don't need Java but you need a native C/C++ application. In any case, a Google search for "gcj java comm" resulted in this as the first hit:

Amazing what a simple Google query can tell you in under a second, huh?

GCJ is not a Java compiler, and it relies on a library called GNU CLASSPATH which isn't Java either. Don't use it, and don't ask about it here, this site is for Java as defined by the Sun/Oracle specifications.

Java classes are cross-platform. If there is a Java runtime for this Linux version then you can run them even if you compiled them on Windows. If there is no compatible Java runtime then you should have done your research before writing the code.

Download and install a JDK from Sun/Oracle for the platform and use the 'javac' command.
