1. I'm new to Netbeans and Desktop App Development, but want to use the
Netbeans Platform to develop simple Desktop database applications; thus I ran
through this tutorial for the first time tonight. I'm using Netbeans IDE 8.2,
with JDK 1.8.
2. I'm almost positive this basic question has probably been asked before and
likely resolved, but I cannot find answers after trying to do so for some time.
Your recent migration over to Apache has removed a lot of the help/forum
archives and history. The link to full source code for the tutorial was broken
and sent me to a generic Oracle site. I cannot find a solution in
StackOverflow or anywhere else, and would appreciate knowing how to
troubleshoot the basic view step of the tutorial before moving on.
3. I submitted this email first from an online form, but haven't heard an
acknowledgement that it was received, so now I'm sending it directly via my
email. I apologize if this is therefore submitted twice - just like with the
broken Oracle links, it's difficult to tell in the transition to Apache just
how to submit help requests.
Now, for my specific issue:
For the very first view exercise, I tried to follow the tutorial exactly as
specified using Derby database, and all of the project/code base names exactly
as provided. I cannot get the CustomerViewerTopComponent.java module to
compile as specified after inserting the provided code snippet at the end.
Dependencies were registered as specified in both the CustomerLibrary and
CustomerViewer modules, and the "Fix Imports" command was run. All errors
cleared up but one, on the "for (Customer c : resultList) {" line. I went
ahead and tried to build, though, and the compiler error messages are as
follows:
---------------------------------------------------
C:\Users\Jeff\Documents\NetBeansProjects\DBManager\CustomerViewer\src\org\shop\viewer\CustomerViewerTopComponent.java:113:
error: illegal start of typefor (Customer c : resultList)
{C:\Users\Jeff\Documents\NetBeansProjects\DBManager\CustomerViewer\src\org\shop\viewer\CustomerViewerTopComponent.java:113:
error: ')' expectedfor (Customer c : resultList)
{C:\Users\Jeff\Documents\NetBeansProjects\DBManager\CustomerViewer\src\org\shop\viewer\CustomerViewerTopComponent.java:113:
error: <identifier> expectedfor (Customer c : resultList) {3 errors1
warningC:\Program Files\NetBeans 8.2\harness\suite.xml:187: The following error
occurred while executing this line:C:\Program Files\NetBeans
8.2\harness\common.xml:225: Compile failed; see the compiler error output for
details.BUILD FAILED (total time: 11 seconds)
----------------------------------------------------
For some reason, the compiler doesn't seem to be recognizing "resultList" from
its declaration in the line above: " List<Customer> resultList =
query.getResultList();" As far as the syntax highlighting, resultList displays
in green color on the "List<Customer>..." line but displays in black italics on
the following "for (Customer c : resultList) {" line. And this "for" line is
underlined red as well.
I thought I inserted the provided code snippet in the correct spot. Here is a
larger context of where I actually pasted it in the source code (after the
readProperties method):
--------------------------------------- void
readProperties(java.util.Properties p) { String version =
p.getProperty("version"); // TODO read your settings according to their
version }
EntityManager entityManager =
Persistence.createEntityManagerFactory("CustomerLibraryPU").createEntityManager();
Query query = entityManager.createNamedQuery("Customer.findAll");
List<Customer> resultList = query.getResultList(); for (Customer c :
resultList) { jTextArea1.append(c.getName() + " (" + c.getCity() + ")" +
"\n"); }}
<END OF FILE>-----------------------------------------
Any assistance provided would be greatly appreciated!
Thanks,Jeff
