ThanksThat code isn't where your error is. Here's the errors I get compiling your code:
H:\java>javac InventoryFinal.java
InventoryFinal.java:78: ')' expected
textArea.append("/nTotal value of Inventory "new java.text.DecimalFormat("$0.00").format(total)"\n\n
^
InventoryFinal.java:78: ';' expected
textArea.append("/nTotal value of Inventory "new java.text.DecimalFormat("$0.00").format(total)"\n\n
^
InventoryFinal.java:340: class, interface, or enum expected
import java.io.File;
^
InventoryFinal.java:341: class, interface, or enum expected
import java.io.IOException;
^
4 errorsThe last two errors are on your import statements, which can't be in the middle of a source file. The first two are on this line:
textArea.append("/nTotal value of Inventory "new java.text.DecimalFormat("$0.00").format(total)"\n\n");Which certainly isn't a legal line of Java code. If you want to connect multiple Strings you need to use the "+" operator. -
Class, interface, or enum expected?

C:\Users\Matthew\Documents\server.main.project12>pause
Press any key to continue . . .I really need help with this.This error is often caused by improper matching of braces { }.
Solution: Check the matching opening and closing braces.
Worse, the error could be totally invisible! Often, it is the first thing in the file, before package or import declarations
In that situation, it could be caused by a code edited / formatted using a text editor not designed for programming such as Word, which introduces invisible characters in the code.
Solution : In that case, cut and paste the code in a true code editor as Eclipse or NotePad which withdrawing the offending characters.
This error occurs most often in the console (command line), almost never in an IDE. -

}}Is that all a single source file? The import statement(s) need to be at the top, and each import has to be terminated by a semicolon.
Also this is wrong. Case matters.

It is the subclass of a class that has all the methods used here (it wouldn't allow me to add that too as it said it was too many characters, I will post it if need be)
Thanks in advance![http://www.greenfoot.org/|http://www.greenfoot.org/]
It's what we are supposed to use for class.
I've tried to get a more complete error message because then maybe I could figure out whats wrong but that's all that comes up. and it highlights the last bracket. At first I thought it meant the brackets were off but I've triple checked that and I added an extra one in to try that out too and it changed nothing. I've even tried removing certain chunks of code to see if I could isolate the problem and the same error came up no matter what I did.
add- using the compiler in greenfoot.

Class, interface, or emun expected.
When I compile to code I get 60 "class, interface, or emun expected errors. I know that this error usual means that there is a bracket out of place or missing. I went through and add line comments that link the opening and closing brackets together. Can anyone take a look and let me know what I am missing. Thanks.

Weblogic 10.3.2 EJB3 Local Interface in POJO/Helper classes
Hi,
I have a jar file containing all EJB's in application & some Helper classes. I want to access Local interfaces of EJBs in those helper classes. Is there any way I can do it? I've gone through Maxence Button & Jay SenSharma 's blogs about accessing Local interface. but it doesn't help. May be these two guys can help me more here.. My requirement is very simple. Just to access local interface in POJO/Helper classes that are in same JAR file as EJB's. I can't get reference with @EJB class level annotation as Helper classes are called independently from MBean services.. not from any EJB or Servlert.
Please if anyone can tell me how do I get reference of local interfaces, that would be really good.
my environment is
Weblogic 10.3.2

My application was designed based on MVC Architecture. But I made some changes to HMV base on my requirements. Servlet invoke helper classes, helper class uses EJBs to communicate with the database. Jsps also uses EJBs to backtrack the results.
I have two EJBs(Stateless), one Servlet, nearly 70 helperclasses, and nearly 800 jsps. Servlet acts as Controler and all database transactions done through EJBs only. Helper classes are having business logic. Based on the request relevant helper classed is invoked by the Servlet, and all database transactions are done through EJBs. Session scope is 'Page' only.
Now I am planning to use EJBs(for business logic) instead on Helper Classes. But before going to do that I need some clarification regarding Network traffic and for better usage of Container resources.
Please suggest me which method (is Helper classes or Using EJBs) is perferable
1) to get better performance and.
2) for less network traffic
3) for better container resource utilization
I thought if I use EJBs, then the network traffic will increase. Because every time it make a remote call to EJBs.
Please give detailed explanation.
thank you,
sudheer<i>Please suggest me which method (is Helper classes or Using EJBs) is perferable :
1) to get better performance</i>
EJB's have quite a lot of overhead associated with them to support transactions and remoteability. A non-EJB helper class will almost always outperform an EJB. Often considerably. If you plan on making your 70 helper classes EJB's you should expect to see a dramatic decrease in maximum throughput.
<i>2) for less network traffic</i>
There should be no difference. Both architectures will probably make the exact same JDBC calls from the RDBMS's perspective. And since the EJB's and JSP's are co-located there won't be any other additional overhead there either. (You are co-locating your JSP's and EJB's, aren't you?)
<i>3) for better container resource utilization</i>
Again, the EJB version will consume a lot more container resources. -
Error while transporting class interface
hi,
i have developed class interfaces where i'm using a z-structure(eg ZBMTBATCH) for type definition in public section.
The interface is activated and is working fine is development server.
when i transported it in quality, the transport req failed showing error " ZBMTBATCH not found".
This structure is a trans table and is activated.
Same type of error occured in transport req of all other class interface . only difference is the structure.
The class interface throwing this error has one common similarity, the error it is throwing is for the first declaration.
i mean in public section if declaration is of type :
tbatch type ZBMTBATCH
than in transport log its throwing error as "ZBMTBATCH not found"
please suggest some reasonsHello,
Are u transporting the Structure also together with the Class.
If not first add the Structure to a TR and move it to Quality system. Then Re transport the TR with Classes.
Hope this will helps you.

I know what a class is; I know what an interface is. Today I was looking at somebodies code, and in SE24 they have defined a "Class Interface", NOT a class or an interface.
Does anybody know:
1) What is the difference between this and an ordinary interface?
2) How do you create it in SE24 (When you create a new entity here it gives the option for "Class" or "Interface", but not "Class Interface"?What you may be seeing is the description next to the actual class name in SE24, where it says "Class Interface". Is this right? If so, just know that this is a class and the description here is a little misleading. There are only classes and interfaces in regard to obect types, there is not a third.

Urgent...Help Needed.1. Helper Class 2. Connection Pool
Hello,
1. There are few helper classes which has to be
shared b/w session and entity beans. But it
seems,state of the object is not transfered to entity
bean though the class has implemented Serializable
interface. I have archived all the helper class and
copied to j2ee\home\lib directory. The same jar file
is made accessible to server via updating <library-
path> in j2ee/home/config/application.xml file.
2. How can i utilise connection pooling in oc4j. In data-sources.xml, i am using
"OracleConnectionPoolDataSource" class. But i feel that connection pool is not utilised coz server hangs in the middle of the retrieval.
The value of max-connections is 50.
We are actually migrating from Weblogic 5.1.0 to Oracle 9i AS. In weblogic, we had given 10 max connections in weblogic.properties,it is working fine. But i dont understand why it is not working in 9i AS though the max-connections is 50.
Kindly let me know the solution at the earliest as it is very urgent to get the program running...
Thanx and Regards,

J2EE/home/lib dir, NOT specifying it in the application.xml. So everything works fine.
The only thing: never, again: never put these files within WEB-INF and the lib-dir.
With the HelperClasses in both we have only faced massive problems, mostly ClasCastExceptions.
We had once all the helperClasses within J2EE/home/applications/lib, but this requires to
specify this dir within the orion-application.xml within the appl dir in applications-deployment.
It also worked fine.
2. How can i utilise connection pooling in oc4j. In data-sources.xml, i am using ...I'm not sure of this, but I think, the container handles Connection Pooling, no matter what Factory you
specify. But I think, the Class hasn't to be OracleConnectionPool ... but I have to check this (right now

Reference EJB from servlet's action/helper classes
Hello
How to make a reference to stateless session bean from one of the helper classes of a servlet WITHOUT using any of these:
* dependency injection (like @EJB) - I think this is not supported in this kind of class, EJB references can be injected only to servlets themselves or some other things (but not objects of classes "accompanying" a servlet)
* home or local home interfaces (I would like to avoid writing them)
* using mappedName (either in @Stateless or in ejb-jar) - since meaning of this is application-server dependent and thus not portable.
By a "class accompanying a servlet" / "helper class" I mean utility or action classes, like MyActionClass, which would be instantiated and then used by a aforementioned servlet.
Thanks.The EJB dependency must be looked up via the java:comp/env namespace since as you point out
Java EE 5 environment annotations are not supported on POJOs. However, the dependency itself
can either be defined using @EJB on some other managed class in the .war or within the
web.xml. We have an entry in our EJB FAQ that has the details :
https://glassfish.dev.java.net/javaee5/ejb/EJB_FAQ.html#POJOLocalEJB
Also, whenever the client component resides in the same application as the target EJB (which is
required for Local access but not for Remote access) there is no need to use mappedName to
resolve the EJB dependency. It is either automatically resolved if the business interface type of
the EJB dependency is only exposed by a single EJB in the application, OR the beanName()
/ ejb-link attributes can be used to unambiguously identify the target EJB using ejb-name.
You can find more about this in the FAQ as well.
