Embedded Java code with bpelx:exec

When I embed Java code with bpelx:exec, I would like use classes packaged in a jar file. How do I ensure that the jar file is deployed with the suitcase? I tried adding the library to the JDeveloper project (right-click project, choose properties, libraries), but that did not work.

Although the tooling does not expose this functionality yet, the bpel packaging and bpelc command line tool support the ability to put a library in BPEL-INF/lib and using it in the exec activity. You can also put classes in BPEL-INF/classes. Please look at:
[ORACLE_HOME]\integration\orabpel\samples\references\JavaExec for more information.

Embedding Java Code(URGENT)

Hello,
I'm trying to do the following, I'm trying to embed Java code into my BPEL process, I have read the tutorial that explains how to embed a java code into BPEL(http://www.oracle.com/technology/products/ias/bpel/pdf/orabpel-Training-Segment10.pdf) but unfortunately the tutorial discusses only how to call the Entity Bean but doesnt mention where in folders(directory) should the bean itself be placed, where are the imports.
I'm going to start with a simple example, a class called Multiplier that has function square, Here is the code for the class:
//Java Multiplier class
public class Multiplier{
public Multiplier(){}
public int square(int x){
return x*x; }
this is code that will be placed in the EXEC(Java code snippet):
//Java Code Snippet goes here...
try{
Object input= getVariableData
("input","payload","/JavaCode");
String parser= input.toString();
int in= Integer.parseInt(parser);
Multiplier obj1= new Multiplier();
int result= obj1.square(in);
addAuditTrailEntry("The square of the input is:"+result);
catch(Exception en){
addAuditTrailEntry(en);
Where should the multiplier class be located(in which folder in the ecplise)or how will the BPEL refer to it ?
Shouldnt I import the Multiplier class in the EXEC(snippet) where should that line go?
Thanks in advance

After going through the Forum I saw I question similar to mine, and I found out there's an example similar to what I am trying to do at C:\orabpel\samples\references\JavaExec
I tried to make an example almost exactly like JavaExec and I edited my build.xml to be similar to build.xml of the example but I keep getting this error:

Compiling Java code with Japanese characters

I have a Java code with some Japanese characters. My compiler doesn't recognise these characters and gives me error messages.
Please help me.

Obviously it's not the copmiler's fault. You need to fix your code.
Here is a link to the Java Language Specification.
The link is to section 3.8 - Identifiers.
It describes the acceptable naming:
http://java.sun.com/docs/books/jls/second_edition/html/lexical.doc.html#40625
Perhaps your editor is not saving the text file in an appropriate format.

Hi
some times this error comes if the Packages for using JAVA are not i mported into BPEL Weused to get same error but after importing the packages the error usually used to be solved please check whether if the class files which you are using are correctly imported or not
ex

<import location="java.io.*"
importType="http://schemas.oracle.com/bpel/extension/java"/>

Calling EJB with bpelx:exec lookup-methode

I created a EJB3.0 that I try to lookup in a BPEL Java Embedding activity with following code:
try {
Object homeObj = lookup("ejb/stateless/LoginDataBean#com.unisoa.logindata.LoginDataBeanRemote");
} catch (Exception ex) {
   addAuditTrailEntry(ex);
}I get Logged exception "NameNotFoundException" as result. Unfortunately I do not have a clue why this happens.
To prove the lookup-name I checked jndi-tree and it shows Binding-Name: ejb.stateless.LoginDataBean#com.unisoa.logindata.LoginDataBeanRemote. So jndi-name seems to be ok.
Also I generated a java client with JDeveloper that works well too.
Code Java Client:
Hashtable env = new Hashtable();
env.put( Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory"; );
env.put(Context.PROVIDER_URL, "t3://server:port");
InitialContext context = new InitialContext( env );
LoginDataBeanRemote loginDataBeanRemote = (LoginDataBeanRemote)context.lookup("ejb/stateless/LoginDataBean#com.unisoa.logindata.LoginDataBeanRemote";);The bean I try to call is following:
@Stateless(name = "LoginData", mappedName = "ejb/stateless/LoginDataBean")
@Local(LoginDataBeanLocal.class)
@Remote(LoginDataBeanRemote.class)
public class LoginDataBean implements LoginDataBeanLocal, LoginDataBeanRemote{
public LoginDataBean() {}
}I did online research but could not find any usefull information. Also I do not know if remote or local jndi-name is necessary for lookup-methode. I am using SOA Suite 11.1.1.3.0.
I would really appreciate some help.
Thx
Pascal

Have you resolved this? I'm struggling with the exact same problem; a standalone EJB Java client works and I can see the mapped name in the soa server JNDI tree etc

Format Java Code with jdeveloper

Hi Everybody,
Can anybody tell me How I can Indent Java Code Automatically using JDeveloper 9i.
It is a facility which is provided in almost all the editor and I believe it should be in jdeveloper also but the problem is I dont know how to go for it.
I will be very kind to anybody who will solve this problem as this will reduce my lot of unwanted work.
Regards,
Amit Jain

If you're looking for a code beautifier (a tool that can apply a coding style to your source code automatically), try the Jalopy extension. It's an open source code beautifier that is tightly integrated with JDeveloper:

Integrating Java code with pre-existing C application

My team has been tasked to develop wizards for a pre-existing C application on Unix. We don't own the C code so we can make only limited changes to the native code.
The challenge is to call the Java wizard from within the C code, and then to allow the Java code to use services and data in the C code. I can call Java from C, and then call C from Java. But the C code that gets called from Java doesn't seem to have access to the data known by the C code that called the Java.
The only way I've thought of to handle this is to pass function pointers as paramters to the Java program, which can then pass the pointers on to the C code that it calls. Is there a way to pass pointers into Java?

But the C code that gets called from Java doesn't seem to have access to the data known by the C code that called the Java.
I don't know exactly what you mean here, unless you're simply saying that the scope of your C data makes it inaccessible between functions.
Is there a way to pass pointers into Java?
Yep - Just treat the pointers as opaque types and wrap them in something large enough for the platform - for example a jlong. You need to be sure to be careful in managing the lifetime of the pointers with respect to the Java objects that hold onto them - for example, with function pointers that come from a dynamically loaded shared library or any data pointers that you might be passing around. You probably want to read the section on native peers in the JNI programmer's guide.

Embedded Java Code - How to retrieve multivalue payload value

I'm working in my SOA-Composite which is used with OIM and our approval process. Here is an example of the payload data:
>
<ns2:RequesterDetails>
<ns2:FirstName>System</ns2:FirstName>
<ns2:MiddleName/>
<ns2:LastName>Administrator</ns2:LastName>
<ns2:Login>XELSYSADM</ns2:Login>
<ns2:DisplayName>System Administrator</ns2:DisplayName>
<ns2:ManagerLogin/>
<ns2:OrganizationName>Xellerate Users</ns2:OrganizationName>
<ns2:Email>[email protected]</ns2:Email>
<ns2:StartDate/>
<ns2:EndDate/>
<ns2:Status>Active</ns2:Status>
<ns2:XellerateType>End-User Administrator</ns2:XellerateType>
<ns2:UserType>Full-Time</ns2:UserType>
<ns2:Role>SYSTEM ADMINISTRATORS</ns2:Role>
<ns2:Role>Test Role 1</ns2:Role>
<ns2:Role>Test Role 2</ns2:Role>
</ns2:RequesterDetails>
>
I am able to retrieve single values with code like this:
>
//Retrieve Requester Login
Object requesterXMLElem = getVariableData("inputVariable", "payload","/ns3:process/ns4:RequesterDetails/ns4:Login");
String requesterLogin = ((oracle.xml.parser.v2.XMLElement)requesterXMLElem).getText();
>
How do i retrieve the multivalue Role values and not just a single entry?
Thanks,
Kevin

I see what i missed with the doube slash, i thought you had a typo and assumed i used it. If i use the following:
//Retrieve Requester Roles
Object requesterRolesXMLElem = getVariableData("inputVariable", "payload","/ns3:process/ns4:RequesterDetails//ns4:Role");
System.out.println("Requester Roles Type[" + requesterRolesXMLElem.getClass() + "]");
int requesterRolesCount = ((oracle.xml.parser.v2.XMLElement)requesterRolesXMLElem).getAttributes().getLength();
System.out.println("Requester Roles Length[" + requesterRolesCount + "]");
String requesterRole = ((oracle.xml.parser.v2.XMLElement)requesterRolesXMLElem).getText();
System.out.println("Requester Roles[" + requesterRole + "]");
I get the following output:
Requester Roles Type[class oracle.xml.parser.v2.XMLElement]
Requester Roles Length[0]
Requester Roles[SYSTEM ADMINISTRATORS]
I am not seeing how to loop through each if the type is class oracle.xml.parser.v2.XMLElement
Thanks,
Kevin

Importing classes with embedded java

I have the following line of code:
Element input = (Element)getVariableData("sourceString");
I'm trying to get the value the the variable 'sourceString' from the bpel process. When I try and compile I get the error:
class bpel.testmq.Element not found.
testmq is the name of my bpel process.
I have tried using javax.lang.model.Element, and org.jdom.Element with no success.
cheers
James

Finally, I think I have figured out all my java issues.
to import java classes all you need to do is enter the following in the source code of your bpel process. This is places after the last line of the process and before the partner links.
<bpelx:exec import="java.util.*"/>
<bpelx:exec import="java.lang.*"/>
<bpelx:exec import="java.rmi.RemoteException"/>
<bpelx:exec import="javax.naming.NamingException"/>
<bpelx:exec import="org.w3c.dom.Element"/>
<bpelx:exec import="java.math.*"/>

Embedded Java in BPEL and exception handling

Hello everybody,
i want to use some embedded java code in my BPEL process (bpelx:exec). This code would sometimes throw exceptions. How can i deal with these exceptions to control my BPEL process? I would like, in a sense, to do some catching of java exceptions but at the BPEL level... for example, my java code would throw an exception, that my BPEL process would "catch" and react the way i want. Is it possible to do that?
Thanks for your help!

you need to throw a com.oracle.bpel.client.BPELFault ..
from the code
* This class represents a standard fault that may be thrown by the server
* during run-time. A BPEL fault has defined, minimally, a QName that
* corresponds to the fault name (there are several standard faults that
* are supported, please refer to Appendix A - Standard Faults in the BPEL
* 1.1 specification for a complete list).
* <p>
* This class can only be used from within a <code>bpelx:exec</code> activity;
* the <code>throw</code> activity can be used from BPEL code.
* <p>
* Additional information (such as a fault variable) can be passed through
* as a part. Currently, internal system errors populate error codes and
* summary messages via parts.
