Combination of support packages invalid.

I am getting the following error in RSPOR_SETUP, but according to note 1013369
this stack is supported. This system is a fresh SR2 install , then I applied
SPS12 , then finally applied SAPKW70014.
Is the error referring to the version 11 of the java classes? How did those even get there?
The Systeminfo shows all java components correctly at SPS12....

Import Java package in JSP

I hope this is an appropriate forum for this query.
I want to be able to access a user-created Java package in JSP.
I have this code:
<%@page import="TPClass.*" %>
<%
xxx = TPClass
session.setAttribute("response",xxx.GetTPResponse());
%>
The error display points to TPClass in the import statement with the message "TPClass not found".
TPClass files are in the same location as the other project files.
I have creatyed and compiled the TPClass package.
Is there more I need to do?
Brenton

I think you are very new to java....
anyway
<%@page import="class name with full qualified package name"%>
like
<%@page import="com.x1.x2.TPClass"%>
<%
TPClass cls =new TPClass();
//then do whatever you want...
%>
hope u understand now.....

JAVA PACKAGES and JSP

i Have two problems one is i am designing a website which consists of a form. I am trying to write the Connectiviy and all other insert statements in seperate java packages and include them in JSP files.
i Have two java packages one is DBUtil(having two java files both dealing with connectovity) and another one is StudentUtIl which has java files that open the connections with database connection and insert data into DB., I am having a big Problem here. How can i call the function in the other java package in the files in this java package. i have openDB()and Close() in the other Db and i want to call these functions in JAVA classes in the other package. How to include a package. Both these packages are in the same File system mounted on a Local directory

Thank you for the reply. I am giving the code i have given the full class name . and now it is giving the following error :
Cannot reference a non-static method connectDB() in a static context.
I am also giving the code. Please do help me on this. i am a beginner in java.

}catch(Exception excep){
The main error is occuring at the following lines connectDB() and closeDB() in the class student manager. The class dbutil is in an another package.with an another file called connectionManager which establishes the connection with DB. The dbutil has the openconnection and close connection methods. I have not yet written the insert statements in StudentManager. PLease do Help me

NoClassDefFound error when using custom Java package in scripting QPAC

Hi,
I compiled a little Java-package (.jar), which contains a class that uses
com.adobe.workflow.datatype.form.FormDataTypeInstanceImpl.
I put my library in the lib folder of JBoss (...\server\all\lib).
Then I'm was trying to invoke my custom class in the scripting QPAC. But I'm constantly getting the error message
NoClassDefFound com\adobe\workflow\datatype\form\FormDataTypeInstanceImpl. I already put
adobe-wkf.jar (and various others) in the lib folder of JBoss. Without ever succeeding. Unfortunately.
I'm going mad about this.
Is there a way to address a custom package in the scripting QPAC, which uses
FormDataTypeInstanceImpl?
Steve

Removing the LiceCycle jars from the lib folder did not work. I still get the same error message.
What I wanted to do is provide some basic utilities, without having to spend a lot of time designing QPAC user interfaces.
My utility class contains methods like this one:
@param
pFormData
@return
@throws
ParserConfigurationException
@throws
SAXException
@throws
IOException
public static
org.w3c.dom.Document formToXml
FormDataTypeInstanceImpl pFormData
throws
ParserConfigurationException, SAXException, IOException
byte
data = pFormData.getXFAData
InputStream objXMLInputStream =
new
ByteArrayInputStream
data
// create new Document object
DocumentBuilderFactory objFactory = DocumentBuilderFactory.newInstance
DocumentBuilder objBuilder = objFactory.newDocumentBuilder
org.w3c.dom.Document objDocument = objBuilder.parse
objXMLInputStream
return
objDocument;
Even without ever invoking the aforementioned method, I get the error
NoClassDefFound: FormDataTypeInstanceImpl. Which is pretty weird.
Do I have to write my own classloader?

How to find classes in a java package

i am writing a java IDE. i want to extract all class names from a java package eg. java.lang (through coding). how can i do that.
Thanks in advance

File file = new File("path to your jar file");
JarFile jf = new JarFile(file);
Enumeration e = jf.entries();
ZipEntry ze = null;
while(e.hasMoreElements()){
ze = (ZipEntry) e.nextElement();
ze.toString(); // gives you the file name
you have to understand java.util.jar java.util.zip packages for working with jar/zip files.
Hope this helps

Problem with Java-Packages in JavaFX-Scripts

Hello!
What I'm trying to do is using a class I've built in my project in a JavaFX-Script, my problem is that the compiler keeps telling me my package wouldn't exist.
My filestructure is basically the following:
src
|-com.foo.java
|-- MyClass.java
|-com.foo.javafx
|-- MyFXScript.fx
I've tried importing the package or just writing the fully qualified classname when trying to create an instance, the messages didn't differ. I'm not at home right now so I don't remember the exact compiler-message, but it was something like "Package does not exist: com.foo.java".
Any ideas? :-)
Kind regards,
Joshua
Edited by: gnrx on Jan 12, 2009 5:55 AM

It works on my system.
MyClass.java
package com.foo.java;
public class MyClass {
    @Override
    public String toString() {
        return "My Class";
MyFXScript.fx
package com.foo.javafx;
import com.foo.java.*;
var myClass = new MyClass();
println(myClass);standard-run:

Java packages and dependency

When java was being developed, what was the philosophy behind allowing packages to be mutually dependent?

Hello Steve,
The Acyclic Dependencies Principle tells us that no cycles should exit in a model depicting the dependencies between packages. From what I can gather this is useful when developing large software systems, as each package becomes a viable work unit for an engineer or small group of engineers to control as a series of releases. If the ADP is not complied with, cycles may exist in the dependencies between packages. If a change is made to one of those packages within a cycle, then an ugly situation develops as the repercussions of the change are looped through the cycle back to its source and so on.
The thing is though, during my readings I came across a statement that said Java packages were mutually dependent. I was just wanting to know why a language that utilises object oriented technology, left the practice of the ADP up to the descretion of the developer? Is the full implementation of ADP on a software system an ideal world scenario?

Java package and c++ header files

What is the difference between importing java package and including header files in c++?

I do not know .. have been away from C/C++ for a long time...
As much as I remember you can only import one header file each time... also when you import a header file you can just call methods from the header file automatically ...
However I could be very wrong on this .. really lost touch from C/C++ ...

Just Starting out with java packages

Hello,
I'm a beginner and I'm starting out with java packages.
I wrote two simple .java files, one test program and one containing a simple class.
Both files are compiling without errors but When I run the program I get an error NoClassDeffoundError.
I use the import <package> statement And I think I'm using the CLASSPATH variable correctly.
SET CLASSPATH=d:\nopol
path for the .java containing the test class is:
d:\nopol\utilities \myapp.
In the test file I use "import utilities.myapp.*.
I would be very happy if anyone could help me
Thanks beforehand
Nopol.

The test file should be in d:\nopol, if it's not a part of your package utilities.myapp. Everything should be compiled from d:\nopol, the test class with "javac ClassName.java" and the class in the package with "javac utilities/myapp/ClassName.java".
Your classpath seems fine for now, though. But yes, do add the period there, otherwise you could run into problems later.

Problem finding native methods in java packages

Hi,
I have a java class which uses some native methods written in OCamL. I wrote a C file which calls the OCamL code, and created the corresponding shared library using the jni. I then tested my java file and everything works fine, I can nicely call the OCamL functions. However, I need this java file to be included in a package, but whenever I add the line:
package somepackage;
on top of the java code, my java file simply doesn't seem to find the C and OCamL implementation anymore :
javac -cp :./path/of/somepackage
-Djava.library.path=/full/path/of/somepackage MyProgram args
Exception in thread "main" java.lang.UnsatisfiedLinkError:functionName
at somepackage.ClassName.functionName(NativeMethod)
I have of course put everything (java, C, .h , libsomelibrary.so, and OCamL files) in a directory called somepackage, and written another java file which creates an instance of the first one from outside the package, imports the package, and calls its methods in main(). It just doesn't work anymore.
I then added a simple hello-world function (not C nor OCamL code) to the java file inside the package. And when invoked from outside, it worked. Question is then... Am I forgetting something to be done, in order to get C and CamL files efectively included in the java package (same as "package somepackage;" in C or OCaml, perhaps)??? Why isn't the java file able to find them inside its very own directory (having into account that without the package definition it worked well)?
Thanks,
PS Im using jsdk 1.4.1 on lunyx redhat 8.0

Did you change the name of the function in the library, too?
If the function name was
"Java_YourClass_functionname",
it should be now
"Java_path_to_your_package_YourClass_functionname".

When should be package invalidated?

Hello guys,
I would need again some help...
My question is: When exactly should be package invalidated?
Consider following situation:
We have two packages, one contains constants (in its specification), the other is reading these constants. Package is reading these constants in package body and package spec as well. Now, when I add a new constant to the first package and recompile it, should this invalidate the other package??? The new added constant is not used in the other package.
In reality, we have a Constant package, containing all constants in its specification. One package (test_pkg) is reading some constant let say form line 100. Now we add new constant let say to line 50. When we recompile the constant package, planty of packages get invalidated because they are reading from it. We recompile all invalid packages. However test_pkg is not invalidated!!! Now if we run the code from test_pkg, it is still reading the constant from line 100, so it is reading it from wrong place and the constant has wrong value! The only thing what help is to recompile the test_pkg.
So it looks like the reference to Constant package wasn't updated.
Why isn't test_pkg invalidated???

From my standard library of responses...
Packages tend to fail because of their "package state". A package has a "state" when it contains package level variables/constants etc. and the package is called. Upon first calling the package, the "state" is created in memory to hold the values of those variables etc. If an object that the package depends upon e.g. a table is altered in some way e.g. dropped and recreated, then because of the database dependencies, the package takes on an INVALID status. When you next make a call to the package, Oracle looks at the status and sees that it is invalid, then determines that the package has a "state". Because something has altered that the package depended upon, the state is taken as being out of date and is discarded, thus causing the "Package state has been discarded" error message.
If a package does not have package level variables etc. i.e. the "state" then, taking the same example above, the package takes on an INVALID status, but when you next make a call to the package, Oracle sees it as Invalid, but knows that there is no "state" attached to it, and so is able to recompile the package automatically and then carry on execution without causing any error messages. The only exception here is if the thing that the package was dependant on has changes in such a way that the package cannot compile, in which case you'll get an Invalid package type of error.
And if you want to know how to prevent discarded package states....
Move all constants and variables into a stand-alone package spec and reference those from your initial package. Thus when the status of your original package is invlidated for whatever reason, it has no package state and can be recompiled automatically, however the package containing the vars/const will not become invalidated as it has no dependencies, so the state that is in memory for that package will remain and can continue to be used.
As for having package level cursors, you'll need to make these local to the procedures/functions using them as you won't be able to reference cursors across packages like that (not sure about using REF CURSORS though.... there's one for me to investigate!)
This first example shows the package state being invalided by the addition of a new column on the table, and causing it to give a "Package state discarded" error...

Use of Java packages in Java stored procedures? (Oracle 10.2)

Hi all-
Does Oracle's Java stored procedures support Java packages? In all the examples I've seen, packages are never used, and when I added one to a test file, it compiled it just fine, but referencing the class from the package itself resulted in a compiling error.
In other words, it seems to make absolutely no difference if I preface my Java class with
package com.mycompany.whatever;
and while I can "import com.mycompany.whatever.MyClass" in another Java file, it seems to not care at all whether I do so or not.
Thanks for any clarification,
Ilford

Hi Ilford:
Sure you can use fully package notation in your Java classes.
Look at this Java source code:
http://dbprism.cvs.sourceforge.net/dbprism/cms-2.1/src/com/prism/cms/core/
All of them are Java Stored procedures.
Best regards, Marcelo.
