Java Class Reference

Hi,
I am in a situation where I need to go through the code for a large application for debugging and obviously I didnt code it. The application is in Java.
OK, Here is what I want to know. Is there anyway to know where the control is being tranferred and from where?
e.g.
Control from Class A is transferred to Class B. Is there any way to find out in class B that the control is coming from class A. What should I do to know this.
Any help would be appreciated.
Thanks

Hai Dude,
thanks for the reply. I found out the solution.
The exact code I added was
Throwable stuff = new Throwable();
StackTraceElement [] stackElements = stuff.getStackTrace();
for (int lcv = 0; lcv < 5; lcv++)
System.out.println ("Filename: " + stackElements[lcv].getFileName());
System.out.println ("Classname: " + stackElements[lcv].getClassName());
It did the trick.
Thanks for your help dude.

Java class reference error in Portal Application

Hello,
I have created a Portal Application Project with the Class
"public class TEST extends AbstractTestComponent implements ITestable"
in order to test the application.
The test works fine with a simple code.
Instead, using the external class HSSFWorkbook in order to create an excel file, the Enterprise Portal Unit Test return the following error:
"java.lang.NoClassDefFoundError: org/apache/poi/hssf/usermodel/HSSFWorkbook"
I have tried to put the ZIP file of class into the folder "dist/PORTAL-INF/lib" and "dist/PORTAL-INF/exlib" but it doesn't work.
Can someone tell me what I have to do?
Thanks and best regards,
Matteo.

Hi,
note that a portal application has two classloaders. one for the public part (src.api) and one for the private one (src.core).
portal components reside in src.core by default. this means you need to load your jar file to the private class loader.
so instead of dist/PORTAL-INF/lib use dist/PORTAL-INF/private/lib

LOADJAVA이용시 JAVA CLASS OBJECT의 권한 문제

제품 : SQL*NET
작성날짜 : 2004-01-14
LOADJAVA이용시 JAVA CLASS OBJECT의 권한 문제
====================================
PURPOSE
Java Stored Procedure를 이용하기 위해 java class를 DB로 load할 때 loadjava를
이용할 수 있다. 이때 loadjava 수행시 권한 오류나, java stored procedure(JSP)의
owner와 다른 owner로 java class를 load하고 JSP에서 사용하는 경우의 권한
부여 방법 등을 확인해 본다.
Explanation & Example
1. loadjava와 dropjava의 간단한 실행 방법 및 관계된 objects들
loadjava command는 가장 간단하게 다음과 같이 지정할 수 있다.
-r option은 db에 load하고서 load된 java object를 compile하는 것이다.
os> loadjava -user scott/tiger -r LJTeset.class
이 문장을 수행하고 나면 다음과 같은 object가 생성된다.
즉, load되는 java class외에도 2개의 테이블과 2개의 index, 그리고 한개의
table이 생성된다.
loadjava를 수행하는 user는 이러한 object를 생성할 수 있는 권한이 있어야한다.
SQL> select object_name, object_type from user_objects;
OBJECT_NAME OBJECT_TYPE
CREATE$JAVA$LOB$TABLE TABLE
LJTest JAVA CLASS
JAVA$CLASS$MD5$TABLE TABLE
SYS_C002172 INDEX
SYS_C002173 INDEX
SYS_LOB0000029869C00002$$ LOB
loadjava후, 다시 dropjava문장을 다음과 같이 수행하는 경우, 이렇게 생성된
6개의 object가 모두 사라지는 것이 아니고 LJTest만 지워지고 나머지는
모두 그래도 남는다.
os>dropjava -user scott/tiger LJTest.class
즉, 일단 한번 loadjava를 수행하면 위에서 LJTest를 제외한 나머지 object는
항상 존재하게 된다.
2. loadjava시 다른 user가 java class이용할 수 있도록 하는 방법
loadjava시 load된 java class를 이용하여 JSP를 생성한 owner에게 다음과 같은
방법으로 권한을 부여할 수 있다.
os>loadjava -user scott/tiger -g public -s -r LJTest.class
os>loadjava -user scott/tiger -g eykim -s -r LJTest.class
이때 -g option이 권한을 부여하기 위한 option이며, -s를 지정하면 동일한
이름의 public synonym이 만들어져서 이 java class를 다른 schema에서도
이용가능하게 된다.
(NOTE) 이때, named PL/SQL에서 role을 통해 부여 받은 권한은 인식하지
못하는 제약사항이 loadjava시에도 그대로 적용된다.
즉, -g다음에 role명을 주는 경우 그 role을 가지고 있는 다른 user가
해당 java class를 이용하여 JSP를 만드는 경우 해당 java class를
인식하지 못하게 된다.
loadjava외에 직접적으로 SQL문장을 통해 권한을 부여하여도 된다.
SQL>grant execute on "LJTest" to scott;
여기서 주의할 점은 반드시 LJTest java class를 지정할 때 큰 따옴표(" ")를
표시하여야만 인식이 된다.
이것은 grant뿐 아니고 sql문장에서 java class를 reference할 때 항상 적용된다.
예를 들어 resolve시에 다음과 같이 하여야 한다.
SQL>alter java class "DBTrigger" resolve;
위의 loadjava 문장에서 -s option을 통해 public synonym을 생성하였는데,
이것은 sql문장을 통해 synonym을 생성하여도 같은 결과이다.
이때, user는 create public synonym권한을 가지고 있어야 한다.
이후 dropjava 수행이 필요한 경우, dropjava시 -s option없이 public synonym도
함께 drop되므로 drop public synonym도 필요하다.

How to reference JAR files in stored java class ?

I don't know if it's exactly the right place to post this, I hope it could be :-)
Here is the problem :
I developped a Java class with some public static functions.
To store this class in Oracle, I use the SQL below :
CREATE OR REPLACE AND COMPILE JAVA SOURCE NAMED "SYSTEM"."MYCLASS" AS
// ... (Java source code) ...
This works pretty well with simple functions, but we need to import specific class. Here is for MQSeries : import com.ibm.mq.*;
When using the SQL to put the Java class, we get an error message saying that the class wasn't correctly compiled. It seems it's about the import.
The question is : how to proceed to reference the JAR files needed so that my class can correctly import the needed packages ?
Thanks in advance,

Here is a simple example of code :
CREATE OR REPLACE AND COMPILE JAVA SOURCE NAMED "SYSTEM"."TEST" AS
import com.ibm.mq.*;
public class Test {
public Test() {
try{
MQQueueManager manager = new MQQueueManager("");
catch(Exception e){
In this way, I get message "Warning : Java create with compilation errors".
When I comment the line of the MQQueueManager object creation, it is well created.
Any ideas ?

What you suggest as a good summary of ADF Java classes? What about a detailed reference?

Hi everyone,
When I was a forms developer, I was quite familiar with the built-ins. Now that I am learning JDeveloper, I am trying to get acquainted with the various Java classes that support ADF development. A summary of classes for the model, controller, and view layers would be very helpful. One document that is good (which is included in the documentation below) can be found here: ADF Equivalents of Common Oracle Forms Triggers.
As far as reference materials, these two seem to be good:
Oracle Fusion Middleware User’s Guide for Oracle JDeveloper 11g Release 2 (11.1.2.2.0)
Oracle Fusion Middleware Fusion Developer’s Guide for Oracle Application Development Framework 11g Release 2 (11.1.2.1.0).
Any suggestions that might help me make the best use of my ADF study time would be appreciated!
Thanks.
James

Circular reference calling the ImportFileGeneratorTask java class

Hello,
I am facing an issue when I generate in my build.xml the import file with the ImportFileGeneratorTask java class:
Unable to sort files due to circular reference: ROLE-R_ALL_G_T_USER.xml -> ROLE-BR_ALL_G_T_USER.xml -> ROLE-R_ALL_G_T_USER.xmlIt occurs in the ObjectDependencySort java class because a Business Role contains an IT Role.
Here is an extract of my build.xml:

Thanks,

you can just get rid of the ParentRoles tag in every Role. This does make the circular reference to disappear and roles are still contained in each other correctly as far as I tested it.

Adobe, I think, are quite happy leaving the StageWebView as a highly efficient and low-level component accessing native functionality, so I wouldn't hold my breath on them extending it.
That said, I believe somebody did implement an ANE that gives much more access and, according to the docs, does allow Javascript access.

Java custom class reference xsd file

I have an java app that fails when loaded into Oracle(it works when not in Oracle), and the failure is related to the accessing of info in an xsd file...I have tried loading these into XDB and played with permissions etc...What is the easiest way for the java classes to see an *.xsd file...does it even need to be in the DB? Ive looked around quite a bit, but cannot find the applicable documentation. This link is perfect for java sp implementation...but there is no reference to any xml techniques in this link...http://www.cs.umb.edu/cs634/ora9idocs/java.920/a96659/toc.htm
Thanks in advance for any info

You won't see any file names for custom classes in the Editor (there may be fragments of it in places..but it's hard to describe in this format). Ultimately, you need to know how to Interface your Java Class; Instantiate a Reference of it's type (unless you use static methods..which I like to do a lot with custom common utilities I use)...
CustObject custObj = new CustObject(Constructor);String sCustDataFromObject = custObj.getCustData(params);
Let me know if this was helpful in anyway..
If you don't know how to use your Java Class..ask whomever packaged the code and/or use a Java Decompiler (I use JD-GUI on the Macintosh) to see how to use the Class..

Passing complex java class by reference to JNI

Hello all ,
I need to pass a java class (with primitive class members) to JNI and let the C++ update class member values so java would automatically get the new values.
I also would like to return such a class from JNI to java..
Is it possible ?
I would be happy to get some examples ...
thanks

1. Passing an object is trivial. Define the java class, instantiate an object, and pass it as a parameter of your native method.
2. Calling methods of that object is standard JNI. You must
o Look up the class.
o Look up the method.
o Call the method.
3. Returning a java object from C is trivial. Just make it a parameter of your return statement. However you might want to think about whether you really need to do that; if it was an object passed with the native method call, then the object already exists within java. Otherwise, you will have to consider using JNI to instantiate java objects.
Start with the tutorials. If this project gets extensive, then I recommend buying a book on JNI.

Is there a way to create a Java class based on what's defined in a schema?

I have a set of schemas that define what messages I will get as an XML stream (sent as UDP packets). Is there a way to parse the schemas into a set of java classes that match the fields in the schema? If so, next think would be to feed a string or byte array to instances of these objects and have a method that parses it and fills all the fields. But is the first part possible? Somebody linked http://www.cafeconleche.org/books/xmljava/chapters/ in another thread, but that seems to be for regular XML, not schema, unless I'm confused which is entirely possible, I'm new to XML and using it in Java in this way.

For future reference, [Java API for XML Binding|http://www.dummies.com/WileyCDA/DummiesArticle/Building-Custom-Code-with-Java-API-for-XML-Binding-JAXB-.id-1489,subcat-BUILDING.html] (JAXB) allows for [generation of Java classes|http://www.oracle.com/technology/pub/articles/marx-jse6.html] from XML Schema (or even DTD) using its xjc compiler.

Help me which JNDIFactory to use to access EJB from a java class of JAR

I am confused in understanding the different JNDI factories
RMIInitialContextFactory, ApplicationInitialContextFactory and ApplicationClientInitialContextFactory
And the different namespaces like global, container local and component local.
Especially is there any relationship between the JNDI factories and the namespaces?
Or are they related to the deployment descriptors.
Because in application specific deployment descriptors (orion-ejb-jar.xml), we just map the JNDI location with the object (or its reference from ejb-jar.xml). We dont specify it can be accessed from this factory or that.
Shall we access an EJB from using any JNDI factory?
Specifically, I am stuck with what Factory to use to access an EJB from a Java class in a library (jar). The JAR is packaged with the EAR which contains the EJB Jar that I am trying to access.
THANK YOU

Ed,
As Robin said, I think you need code similar to this:
Context c = new InitialContext();
Object o = c.lookup("java:comp/env/Name");where Name is the name of your EJB as it appears in the "ejb-jar.xml"
deployment descriptor XML file.
Good Luck,
Avi.

PI 7.1 Enhancement pack 8: still error when referencing java class in xslt

Hi
I am getting an error in PI 7.1 EP 8 Repository when I try to use an xslt in which I make a reference to a java class. The error is:
Transformer Configuration Exception occurred when loading XSLT XCBL_invoice_stylesheet.xsl; details: Could not compile stylesheet
I use this xslt:
<xsl:template match="/" xmlns:util="dk.dongenergy.pi.mapping.Utilities_datetime">
          <html>
<B><xsl:text>Received: </xsl:text><xsl:value-of select="util:getCurrentDateTimeFormatted()"/>
I have imported the java archive successfully and it is working in XI 3.0 and it is working if I comment out the reference to the java class in the xslt.
the java class looks like this:
package dk.dongenergy.pi.mapping;
import java.text.SimpleDateFormat;
import java.util.Date;
public class Utilities_datetime {
*     public static String getCurrentDateTimeFormatted() {*
*          Date now = new Date();*
*          SimpleDateFormat formatter = new SimpleDateFormat("dd MMM yyyy HH:mm:ss");*
*         return formatter.format(now);*
We have applied enhancement pack 8 on PI 7.1 as suggewsted in this note, but that has not done the trick:

Java stored proc from proxy Java classes generated from a web service?

Hi gurus,
I have searched "Java Stored Procedure" on this forum but could not find what I am looking for, so I have to post again.
I need to use a web service and my client app is written in PowerBuilder 11 (Sybase), which claims that it will create a datawindow from a web service. Well, it turned out that PB can only handle simple stuff (it works with a very simple wsdl from the internet) but can't handle more complex ones that we need to use. So I am thinking about using Oracle JDeveloper(JDev) to create the web service proxy for the web service and then load it into Oracle as a Java stored procedure so that PowerBuilder can call the procedure. JDev succsfully generated the proxy and a few Java classes. My question is, do I need to load all the classes into the database? If yes, will the reference to the package work? For example, in a JDev generated class (the soap client class), it has package MyJdev.proxy; at the top. Or, will it work if I load all the classes included in package /MyJdev/proxy into the database?
Thank you very much for any help.
Ben

For the java stored proc called from pl/sql, the example above that uses dynamic sql should word :
CREATE OR REPLACE PACKAGE MyPackage AS
TYPE Ref_Cursor_t IS REF CURSOR;
FUNCTION get_good_ids RETURN VARCHAR2 ;
FUNCTION get_plsql_table_A RETURN Ref_Cursor_t;
END MyPackage;
CREATE OR REPLACE PACKAGE BODY MyPackage AS
FUNCTION get_good_ids RETURN VARCHAR2
AS LANGUAGE JAVA
NAME 'MyServer.getGoodIds() return java.lang.String';
FUNCTION get_plsql_table_A RETURN Ref_Cursor_t
IS table_cursor Ref_Cursor_t;
good_ids VARCHAR2(100);
BEGIN
good_ids := get_good_ids();
OPEN table_cursor FOR 'SELECT id, name FROM TableA WHERE id IN ( ' | | good_ids | | ')';
RETURN table_cursor;
END;
END MyPackage;
public class MyServer{
public static String getGoodIds() throws SQLException {
return "1, 3, 6 ";
null

How to covert XSD to XmlBeans classes in a Java class

Hi,
I have a xsd and need to get getter and setter methods for the elements in the xsd in a Java Class. Please help.

We should set schema type and populate the data as necessary.

Creating an application module in a Java class

Hi everyone,
I'm trying to create an application module from a normal Java class where I don't have access to any HttpSession objects.
I tried to use the method in the documentation
appMod = Configuration.createRootApplicationModule(
                    "full.class.Name",
                    "ConfigurationName");
It's not working though, complaining that it can not find the configuration file which it's trying to locate at full/class/common/bc4j.xcfg.
This file exists at the same path in the BC4J project which this project has a dependency on in the Project Settings dialog.
Is this the right way to create an application module? Can someone please provide a reference to an example.
Thanks

Thanks Frank, but this example is about a stand-alone application, my problem occurs with an application hosted on the application server.
I did more experiments and came up with some ideas but unfortunately, I hit a dead end.
I thought that in order to work around the fact that I cannot set the class loader of the timer, I could change the class loader of the running thread before I create the timer as follows:
Thread.currentThread().setContextClassLoader(
          this.getClass().getClassLoader());
I thought this would give me a SecurityException for sure, but strangely enough it worked perfectly.
Now, all I needed was to move this code from the JSP to my listener. Unfortunately, it didn't work in the listener, also a test that I did in the JSP to make sure that the classloader before and after the above statment is different, showed that in the listener, the classloader of the thread is the same as the one used to load the listener class:
System.out.println(Thread.currentThread().getContextClassLoader()
          .equals(this.getClass().getClassLoader()));
I thought, maybe this is a listener thing, but if I do it in the init() method of a servlet that I could specify to load on startup, it could work, but still, it didn't.
I cannot understand, why is it that the only correct class loader is the one used to load the compiled JSP class?!
Does anyone have any other ideas?
Thanks
