Problems calling java classe using WSIF in BPEL 10.1.3.3

Hi,
I am working on a POC for a telecom gaint in Sweden. One of their requirement is to invoke java library.
Inorder to do it, I have followed the below steps:
1. Wrote a wrapper java code to a class in this library.(Attached with this mail)
2. Using JDEV 10.1.3.3 created a wsdl file of WSIF binding type for invoking this wrapper class.(Attached with this mail.)
3. Created the required fascade classes using the SCHEMAC option in command prompt.
4. Placed all the class files including the wrapper class file in %BPELHOME%\bpel\system\classes
5. Created a BPEL process to invoke the wsif wsdl.
However while Invoking the BPEL process I am getting the error"com.collaxa.cube.ws.wsif.providers.java.WSIFOperation_Java@9ecad : Could not invoke 'authenticate'; nested exception is:
org.collaxa.thirdparty.apache.wsif.WSIFException: No method named 'authenticate' found that match the parts specified"
Can someone tell me how to resolve this issue.
I have to do a presentation on this in 2 days.
Thanks for the help.

Gautham

Calling java classes using bpelx:exec (Java Embedding) Erorr

I try to add java embedding activity.
So, I add code in this activity:

Call java class by using servlet

i written simple servlet with doGet(0. I need call java class when i run servlet
my requirement is when i start the server i will call servlet it will redirect to another page.
but before that servlet will run java class. which i have written externally.
i need to run java class by using servlet then it will redirect to another page.
could you give the proper solution

You don't call classes - you call methods.
There's nothing special about servlets except the requirement that they implement HttpServlet. Servlets and other classes they interact with all get compiled into WEB-INF/classes on the server.
To forward a request to, say, "other.jsp" you do:
getServletContext().getRequestDispatcher("/other.jsp").forward(request,response);

Can not locate Java class using JNI within C++ DLL

I am using trying to use JNI to call a Java class from C++. The Java class uses JMS to send messages to a JMS message queue. At first I coded the C++ in a console application that created the JavaVM and used JNI to access the Java class. All worked fine. Then I called the Java class using JNI from threads and ran into the problem of the Java class not able to locate the JMS related classes. This was solved by placing the following line in the constructor of the Java class.
Thread.currentThread().setContextClassLoader(ClassLoader.getSystemClassLoader());
Then I moved the JNI code from a console application to a DLL in specific an extension DLL that is called by SQL Server or Oracle server. The DLL will use JNI to call the Java class and send messages to a JMS message queue.
The problem I am having now when the DLL code is called by SQL Server the call to
JNI_CreateJavaVM
appears to work correctly but the call to find the Java class using
jvmEnv->FindClass(pName)
fails. It appears the is a class loading problem which occurs due to the fact JNI is called from a DLL. When the VM is created I pass the class path information using the statement
-Djava.class.path=
And as I stated before it all works when running from a console application. I am new to JNI and really need help in the form of some sample code that will solve this problem. I believe I need to somehow load the classpath information from the DLL but I can not find examples on how to do this using JNI. I have tried several ways using URLClassLoader and getSystemClassLoader from JNI and either it does not work or it crashes very badly.
I used the following code to determine what the existing class path is and the string returns empty.
jcls = jvmEnv->FindClass("java/lang/System");
jmid = jvmEnv->GetStaticMethodID(jcls, "getProperty", "(Ljava/lang/String;)Ljava/lang/String;");
jstrClassPath = jvmEnv->NewStringUTF("java.class.path");
jstr = (jstring)jvmEnv->CallStaticObjectMethod(jcls, jmid, jstrClassPath);
m_jstr = (jstring)jvmEnv->NewGlobalRef(jstr);
pstr = jvmEnv->GetStringUTFChars(m_jstr, 0);
Can anyone please help with example code that will solve this problem. Thanks in advance for any help.
Charles�

I have determined the problem occurs when the application/component is compiled using VC 6.0. The test application was compiled using VC 7.1 and works correctly by locating the class path information. If the test application is compiled using VC 6.0 it has the same problem.
The jvm.dll I am using is version 1.4.2.80. Currently this is not an option to compile all the applications that use JNI using VC 7.1 so can someone please tell me how to solve this problem.

Problem calling AS3 class's methods from Flex Project

Sorry if this is a stupid question, but after 2 days of Web
searching and 2 books give up; I am a Java and c# programmer and am
having problems calling AS3 classes (in packages) from Flex Builder
2 Flex Projects; the AS3 classes work great as Flex Builder "AS3
Projects", but when I try to use the classes in a Flex Builder
"Flex Project" I am able to see and set their properties, but
cannot see (through "code completion") their methods (unless the
class extends another AS3 class; and in that case I can see the
base class's methods). Here is the code:
AS3 Example Class:
package asText {
public class CheckWord {
public var strData:String;
public var strAProperty:String;
public var intAProperty:int;
// Constructor
public function CheckWord() {
public function TestMethod():void {
trace("test...");
public function WordLength():int {
var intLength:int = 0;
trace(strData);
intLength = strData.length;
return intLength;
} // From Method WordLength
} // From Class CheckWord
} // From Package asText
The MXML code:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="absolute"
width="442" height="488" horizontalAlign="center"
verticalAlign="middle"
backgroundGradientColors="[#c0c0c0, #c0c0c0]"
xmlns:asTheText="asText.*"
>
<asTheText:CheckWord strData="Test words" />
<mx:Panel title="Welcome to ........" width="337"
height="393" horizontalAlign="center" verticalAlign="middle"
layout="absolute" y="15" x="50">
<mx:Text text="First Name" enabled="true" width="68"
fontWeight="bold" x="27.25" y="36"/>
<mx:TextInput id="txtFName" x="112.25" y="34"/>
<mx:Text text="Last Name" enabled="true" width="68"
fontWeight="bold" x="27.25" y="66"/>
<mx:TextInput x="112.25" y="64" id="txtLName"/>
<mx:Text text="email address" enabled="true" width="87"
fontWeight="bold" x="17.25" y="96"/>
<mx:TextInput width="189" id="txtEmail" left="112.25"
top="94"/>
<mx:Button id="butSubmit" label="Submit" x="95" y="194"
click="asTheText:TestMethod();"/>
..............and so on ............
All this does is give me an 1180 error:
1180: Call to a possibly undefined method TestMethod.
flexConveyMovie1.mxml

Thanks, I have it working; I was not assigning an "ID" to the
"MXML use of the class" (whatever the formal name for that is;
like: <asTheText:CheckWord id="MyText" strData="The Data" />
) and then I was not referencing that ID in what I am refering to
as calling methods for the Class; like:
<mx:Button id="butTest" label="Test Function" x="39"
y="208" click="MyText.TestMethod();"/>
Also, I did some tests on this, and I am shocked that
apparently neither of these two "uses"(?) of a custom AS3 class
actually "call" the Class's constructor. Does that make sense or is
that the result of how I am structuring this?

How to call java class from pl/sql procedure ?

Hello everyone,
My query is..
There is one pl/sql stored procedure which is doing some business logic and storing data in some columns of one table, suppose the table name is 'ABC' .. and the rest of columns of table ABC are getting updated using java class. Now my problem is whenever I insert data in ABC using store proc.. i have to call that java class so that it will update the rest columns ( why java class for updating the columns in ABC is ..because that logic cant be done from pl/sql proc.. it has to be done using java )
and the other thing is.. oracle is in one machine and java is in another .. :(
hope ..u can help me out !!
Thank in advance !!

but that updation have to be done from java code only.. we are using GIS tools .. have to create some shape files and update the column with that shape file.. so creation of shape file has to be done from java code only..
so how to call java class file which is on another machine and oracle in another..

Calling java classes from plsql procedures

I'm attempting to call java classes from plsql procedures which will create cmsdk users, folders, groups etc, however when I attempt to load a java class into the oracle schema using the command:
loadjava -user user/password@database -resolve classname.class
It generates error messages to the effect that classes (cmsdk classes) required by the class cannot be found. The class is loaded and marked with the status "invalid". Is it therefore necessary for me to load the cmsdk packages into the schema?
Cheers
David

Using CMSDK Java API within the database has never been supported
(see Problems loading IFS's java class into database
When we needed to invoke CMSDK code from our PL/SQL code, we used one of two approaches:
(1) use advanced queues to send requests to an external Java program (the CMSDK code, running outside the database) and receive the results back (asynchronous choice); or
(2) make an HTTP request to a Java servlet (the CMSDK code, running in some Java web container like iAS) and get the response back in some custom format (XML or something) (synchronous choice).
It seems to me that the CMSDK Java API was designed to be used only in middle-tier, not in database tier.

Daniel.

How to call java class file from jsp

hi
we need to call java classes (which are written separately in .java file )from jsp file. we need it for our project if anyone knows about please reply us.
bye
siva sankari

you can call the methods in a lot of ways. you could use scriptlets with the
<%@ page import="package.class"%> and then inside instantiate an object
<%
MyClass mc = new MyClass(parameters if any);
mc.theMethodYouWantToCall();
%>or as Madathil has stated,
or use the JSP tags
<jsp:useBean id="anyname" class="classname"/>and then use the getProperty tag
or even Custom Tags

BAD CLASS FILE ERROR WHEN TRYING TO CALL JAVA CLASS IN WEB-INF DIRECTORY

I AM NEW TO THIS FORUM. PLEASE HELP ME IDENTIFY/RESOLVE THIS ERROR - bad class file: /java/tomcat/webapps/ChoiceTel/WEB-INF/classes/XYZ/SMUA.class. OTHER JSP SCRIPTS THAT CALL JAVA CLASSES DO WORK WELL.
THE FUNNY THING ABOUT COMPILIING THIS JAVA CLASS WAS - I HAD TO A jar xvf OF activation.jar and mail.jar IN THE XYZ DIRECTORY BEFORE SUCCESSFULLY COMPILING SMUA.
THE CALL BEING MADE FROM THE JSP SCRIPT IS AS FOLLOWS:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<HTML>
<BODY>
<%@ page import="XYZ.*" %>
<%!
%>
<%
SMUA sndmail = new SMUA();
sndmail.postMail ("[email protected]","Test Subject","What Message","[email protected]");
%>
</BODY>
</HTML>

Dude. Please don't shout. If your keyboard is like mine, it can produce both upper and lower case letters. Please use them appropriately.
Do you have the activation.jar/mail.jar available in the WEB-INF/lib directory for this application?

B1if Call Java Class

I am attempting to call a java class using the Call Java Class atom.
Java Class Name: full name of the java class to be called (boldjar must be available in the B1i base pathbold)
Where is the B1i base path?
I have created a simple java class the implements Callable that simply returns 1.
The exception I get com.sap.b1i.xcellerator.XcelleratorException: XCE001 Nested exception: com.sap.b1i.bizprocessor.BizProcException: BPE027 Could not get an instance for 'Callable'-class
I have pasted the jar file in just about every path I can think of and still get this exception.
Does anyone have a simple example of what the class should look like? The callable interface only has a single function named call which does not take parameters. How do we create a class that accepts parameters?

Well I found this under Control Center -> Development -> BPC Reference
User defined Java-Classes for the Call-Atom via the 'Callable' interface
com.sap.b1i.bizprocessor.Callable
This interface must be implemented by classes intended to be called by the B1iBizProcessor via the Call-Atom. Instances of these classes are subject of internal pooling if they do not indicate after a usage that they should be destroyed. In order to be able to create them internally in a generic way, they have to implement a parameterless initializer !!!
I just searched the entire BizStore for com.sap.b1i.bizprocessor.Callable but was unable to find it.
I also searched Google for com.sap.b1i.bizprocessor.Callable and it only come up with my posts.
I also searched the SAP Partner Portal, and SAP SDN with no avail.
Is this functionality only for internal SAP use?

Call Java Class and Methods from ABAP

Hi
I install de JCo, But how i can call java class and methods from ABAP?. somebody has an example?
The tutorial say that's is possible, but don't explain how do that?
Thanks.
Angel G. Hurtado

If you need only simple java program, you do not need to install JCo. The following codes can call java class.
DATA: COMMAND TYPE STRING VALUE 'C:\j2sdk1.4.2_08\bin\java',
      DIR TYPE STRING VALUE D:\eclipse\workspace',
      PARAMETER TYPE STRING VALUE 'Helloworld'. "here the name of your java program
CALL METHOD CL_GUI_FRONTEND_SERVICES=>EXECUTE
   EXPORTING
     APPLICATION = COMMAND
     PARAMETER = PARAMETER
     DEFAULT_DIRECTORY = DIR
   MAXIMIZED =
     MINIMIZED = 'X'     "If you need the DOS window to be minimized
EXCEPTIONS
    CNTL_ERROR = 1
    ERROR_NO_GUI = 2
    BAD_PARAMETER = 3
    FILE_NOT_FOUND = 4
    PATH_NOT_FOUND = 5
    FILE_EXTENSION_UNKNOWN = 6
    ERROR_EXECUTE_FAILED = 7
    OTHERS = 8.
Tell me if it works.
