SQL Developer load Java error

Question

Hello, I'm trying to load Java code to my Oracle SQL developer. On Load java, I choose Java source from my hdd (from NetBeans destination folder) and I get the below error. Any help?
error code:
    Error in Source Code 
    &Exception in Stack Trace 1 of 1 
    java.sql.SQLSyntaxErrorException: ORA-24344: success with compilation error 
    ORA-06512: at line 1

        at oracle.jdbc.driver.T4C8Oall.processError(T4C8Oall.java:879) 
          ......  here is the code. It works well in NetBeans and I'm trying to load it in SQL Developer in .java file

Answer 1

Hi,
This could be one of those cases where using Java 7 versus Java 6 makes a difference, or perhaps there is some conflict with the JDBC driver version. So, a few things to try...
1. Make sure your installation's SetJavaHome line in ...\sqldeveloper\sqldeveloper\bin\sqldeveloper.conf points to a Java 6 JDK.
2. If (1) does not work, also uncheck the Use OCI/Thick driver box in Tools -> Preferences -> Database -> Advanced.
3. If (1) and (2) do not work, also copy the ojdbc6.jar from any Oracle client you might have installed to your installation's ...\sqldeveloper\jdbc\lib directory
I would think doing just (1) should be sufficient. If on Mac OS, use sqldeveloper-Darwin.conf instead.
Hope this helps and please post back here and let us know, one way or the other,
