How to call Java Objects from ESB?

I don't know whether its possible but if there is a way please let me know I'd really appreciate.
I'm sending message to the JMS queue and I've created JMS adapter that I expect to be triggered when message gets into the queue. The message is an xml file that I read and look up some values that are Java classes and methods that I want to call. So how do I configure ESB to call Java Classes. I tried to look at the routing rules.
Regards

You could create the wsdl yourself and instead of the soap:binding use the java:binding
not sure if this works...just a guess.

This depends on the version of your Netweaver Java AS. If you are running 7.0, you will have to use the Jco framework. The Jco framework is deprecated since 7.1 though. If you want to build a RFC server in 7.1 or higher, it is adviced that you set it up through JRA.
Implement an RFC server in 7.0:

How to call java method from workflow script?

Hi
I have a requirement of updating field value 'Document Status' based on review/approve of content from Workflow and hence need to update the version number. For that I need to call my java method from workflow during submit of review/approve condition. Please let me know how to call java method from workflow?
Is there any alternative better way to achive this requirement from workflow? Please suggest.
Thanks,
Sarang

OK. So, I think we can all conclude that you don't need to call any Java method, can't we? And, that wfUpdateMetadata is the command that will update your metadata.
Now, the question is what are its arguments. It has two - the first is the name of a custom metadata field to be updated (let's suppose that one field is called xMinorVersion, and the other xMajorVersion), the other is the new value, e.g. <$wfUpdateMetaData("xMinorVersion", "New value.")$>As for new value - do you insist on using strings? Since you want to increase the value, it would be more convenient to work with numbers. For instance, with integers you could go with <$wfUpdateMetaData("xMinorVersion", xMinorVersion + 1)$>With strings you will need to convert it to numbers and back to strings. Besides, what happens if you have more than 100 minor versions? (you mentioned you want to add 0.01, but that would finally increase the major version, wouldn't it?) So, I think these two numbers are independent (perhaps, with exception that increase on the major version set the minor version to .00).
If you want to present it, you can use profiles that will construct for you the representation 2.304 out of MajorVersion = 2, MinorVersion = 304
Solved?

How to call Java API from BSP?

I have a requirement to call Java API from BSP application.
I have checked the forum and found that it is possible by using some ABAP codes.
However there is no pointer on how this is done.
Can someone explain the details on how to call Java API from BSP is done?
I found class CL_EJB_JAVA_OBJECT_METHODS to call a method in EJB but can't find function or SAP class to call Java API.
Actually is there any BSP extention which can used to call Java API?
Thanks,
Hendri

check out these weblogs, it should give you an idea how to go about it.

Hi nuttynibbles,
Before the class declaration in partA.java, you must have an import statement like :
import someDirectory.partB;
public class partA {

How to call Java method from XSLT??

Hi All,
Jdev 11.1.1.3.0
I have a requirement to implement that, I have to call Java method from XSLT. Could anyone please suggest to implement that??
Thanks,

As pointed by others, you must expose your method as a custom function, registering with JDeveloper (for development time) as well as with SOA Suite (for runtime).
In the link below you will find a simple step by step example:

How to call java method from C ?

Hello,
I try to call a native method from java which calls java method from the same class. Exception (noSuchMethodError) is thrown. Any ideas?
Thanx in advance !
here is the source of the native method :
JNIEXPORT jint JNICALL Java_TestDll_Proc_1Mul_1Int_1Var_1Var_1Stdcall (JNIEnv * env, jclass jcl, jint jarg1, jint jarg2) {
int arg1;
int arg2;
int arg3;
jint res;
char * ch = "test";
jfieldID fid;
jmethodID mid;
int (* procedure) (int *, int * ,int *);
int mch;
arg1 = (int )jarg1;
arg2 = (int )jarg2;
procedure = GetProcAddress(libraryHandle,"Proc_Mul_Int_Var_Var_Stdcall");
procedure(&arg1,&arg2,&arg3);
res = (jint) arg3;
printf("(*env)->GetMethodID(env, jcl, \"test\", \"()V\");\n");
mid = (*env)->GetMethodID(env, jcl, "test", "()V");
printf("(*env)->CallVoidMethod(env, jcl, mid);\n");
(*env)->CallVoidMethod(env, jcl, mid);
return res;
here is the source of the java file:
public class TestDll {
static {
System.loadLibrary("testdllwrap");
System.out.println("java: Library testdllwrap.dll loaded");
public TestDll() {
public native int Proc_Mul_Int_Var_Var_Stdcall(int jarg1, int jarg2);
public void test() {
System.out.println("java: test()");
public static void main(String[] args) {
TestDll access = new TestDll();
int a = 5;
int b = 6;
int c = 0;
System.out.println("Calling Proc_Mul_Int_Var_Var_Stdcall");
c = access.Proc_Mul_Int_Var_Var_Stdcall(a,b);
System.out.println("Java Result = " + c);

Something is wrong with the code you posted here.
Since your native method is not static, it should have the jobject instance as a parameter in the function prototype, not a jclass. Also, you should be calling CallObjectMethod with a jobject, not jclass.
Check out Jace at http://jace.reyelts.com/jace.
To call the java method you would do:
JNIEXPORT jint JNICALL Java_TestDll_Proc_1Mul_1Int_1Var_1Var_1Stdcall
(JNIEnv * env, jobject jTestDll, jint jarg1, jint jarg2) {
TestDll testDll( jTestDll );
testDll.test();
}God bless,

Newbie question on how to return java objects from java stored procedures

Hi,
As you may guess, i'm new to this.
I have a stored procedure that does some calculations and creates a list of java objects as the result of the query.
How would I return the list from the database to the client application?
Would I have to create an Oracle type that maps to the java object?
Please help.
Jag

Hi Jag,
Your question is very vague (to me). Perhaps you could post what you have done so far? Have you tried looking through the Sample Code page of the Technet Web site, or tried searching the Ask tom Web site, or MetaLink?
Good Luck,

How to call Java Validations from MDM Workflow

We have some Java Validations which have to be triggerd from the Workflow.
We do <b>NOT</b> want to use the Enrichment Framework for doing this.
How can we call these Java Validations from the Workflow?

Hi Adhappan,
As I see, these kinds of validations are not possible as of now. I'm not very sure if VISIO internally can refer to the JAVA validations, but otherwise this is not possible with current version of the product.
