Input for java embedding

Hi,
Is it possible to pass inputs to the java embedding activity from the bpel process? If yes how do we do that?
Thanks,
Phani

Hi Phani,
There are getVariableData() and setVariableData() methods that you can use from within the embedded Java for accessing BPEL variables and updating these respectively.
There is a lot of information to be found in the BPEL documentation.
Happy programming, Sjoerd

Input for Java in the BEx Web Template Installer

Hello,
When you run the BEx Web Template Installer by choosing the "Complete BI PostInstallation" template and clicking Execute Template, you receive two input areas, one for ABAP and one for JAVA. Do the input values for the JAVA section apply to the BI system or the Portal system?
Thank you,
Janice

Hello,
Yes, these seetings apply to the Business Intelligence Java Components (BI Java), but I am wondering if this is the means to connect to our Portal system or whether the Portal connection is done a different way? When I call transaction RSPLAN -
> Hit on 'Start Modeler'. -->Log on to J2EE/PORTAL, I am directed to the "webdynpro" URL. I receive the following error message "The system is unable to interpret the SSO ticket received". We already have SSO configured between BI and the Enterprise Portal, so does it need to be configured for BI also and if so why?

Java Embedding for writing string into file

Hi ,
According to my requirement I need to create a file and write string data into file.
This string data I am getting as a output of the partner link. Their is 5 string variable which I need to write in file .
I want to use java Embedding activity .
So plz provide me any solution or any link.

Hi,
Why would you want to do this with java embeding? Why not just use the assign activity to create/concatenate the string and then write it to a file with the file adapter?

Problem with socket connection through Java Embedding...

We are trying to create a simple socket connection to a socket server through BPEL PM using the Java Embedding component.
BPEL Process : Client makes an asynchronous request. Passes an input variable. The input variable is sent to the Server Program through a socket connection through the Java embedding component.
Server: We are running a simple Socket Server program from command prompt.
The code below works fine as long as we do not try to receive a response from the server (Commented Code).
If we uncomment the code and try to receive a response, it refuses to create an instance for the BPEL Process. And sometimes restarts the BPEL Server.
Client Code:
String msg="NONE";
try{
org.w3c.dom.Element input = (org.w3c.dom.Element) getVariableData("inputVariable","payload","/client:clientProcessRequest/client:input");
msg = input.getNodeValue();
Socket clientsoc=new Socket("ServerIP",1000);
PrintWriter out1=new PrintWriter(clientsoc.getOutputStream());
out1.write(msg);
out1.flush();
BufferedReader cin1=new BufferedReader(new InputStreamReader(clientsoc.getInputStream()));
msg=cin1.readLine();
setVariableData("outputVariable","payload","/client:result",new String(msg));
clientsoc.close();
catch(UnknownHostException e)
System.err.println("Don't know about host: dev.");
System.exit(1);
catch (IOException e)
System.err.println("Couldn't get I/O for "+ "the connection to: dev.");
System.exit(1);
}

Java Embedding bug in SOA Suite 11g BPEL??

I am beginning to wonder if there is a 'bug' in the SOA Suite 11g, BPEL, Java Embedding activity? Need some help as soon as possible – does the Java Embedding activity work in SOA Suite 11g?
Have tried the following on Jdev 11.1.1.1 and Jdev 11.1.1.3 – get the same error message (see below for error message).
Thanks for any help - Casey
I created a simple composite app by:
1.     Created a Composite with BPEL Process
2.     Created a BPEL variable by the name of Variable and a Simple Type of string      ({http://www.w3.org/2001/XMLSchema}string)
3.     Added an Assign activity (Assign_1) and assigned the value of “Test Var” to the variable Variable using a Copy operation.
4.     Then, after the assign activity, added a Java Embedding activity (Java_Embedding_1) with Java Version set to 1.5 and the following code:
+try{+*
String var;*
var=(String)getVariableData(Variable);*
System.out.println(var);*
+} // end try+
+catch(Exception ex){+*
System.out.println(ex.getMessage());*
+}// end catch+
Compiled and got the following error message:

Ensure that the class path is set correctly. If this happens on the server side, verify that the custom classes or jars which this BPEL process is depending on are deployed correctly. Also verify that the run time is using the same release/version.*

You probably want to try the SOA Suite forum for OSB questions.

There is an excellent book also:

The documentation goes over the fundamentals, but the book will be better for step by step examples.

Getting error while calling external Jars in BPEL by using Java embedding activity in soa 12c

Hi,
I am trying to use an external Jars for the business logic implementation. Here I need to pass XML as input and
and I expect the "Password " field has to be return.
Following are the steps I have followed:
1) Created a java project with sample class and added the external jars into the project "Libraries &Classpath".
2) Created a jar file out of it.
3) Created a BPEL project with Java Embedding.
4)Wrote the java code in java embedding activity.
4) Added the above created jar file to the BPEL project's lib/jar and added in SCA-INF/lib project folder as well.
5) Imported the package with the class as in the jar (e.g <bpelx:exec
import="pkg.testInterface"/>)
6) Deploy the BPEL project.
while deploying the SOA build is sucessful but my depoyment is incomplete.
error:
advices will be great....
Regards,
Dilip

Hi,
Can you confirm if the BPEL Version is 1.1 or 2.0.
If you are using BPEL 2.0 you need to import the required jar/class file as:
<import importtype="http://schemas.oracle.com/bpel/extension/java" location="pkg.testInterface"/>
For BPEL 1.1 the syntax to import other jar/class file is:
<bpelx:exec import="pkg.testInterface"/>
If you import the classes in the correct format you will not face any deployment error.

Java Embedding BPEL activity connecting to UCM Stellent

Hi..
Im trying to connect UCM (Stellent) through Java embedding BPEL activity. The code as shown below.
****java embed in BPEL*******
SearchImpl searcont = new SearchImpl();
Element ssn = (Element)getVariableData("inputVariable","payload","/client:BPELContentProcessRequest/client:input");
int resultlen = searcont.StellentImpl(ssn.getFirstChild().getNodeValue());
addAuditTrailEntry("Result Count is : " + resultlen);
System.out.println("Executing SearchImpl in BPEL: result count is: " + resultlen);
setVariableData("outputVariable", "payload","/client:BPELContentProcessResponse/client:result", new Integer(resultlen));
****java embed in BPEL*******
We are using SOAP wsdls of Stellent to get content information. As such here we are using Search.wsdl and converted to web proxies and thereby import them in Java codes.
When we deploy the BPEL process in SOA server we get the follwoing error in the Audit trail.
2009/01/05 18:41:36 "{http://schemas.oracle.com/bpel/extension}runtimeFault" has been thrown.less

On checking the server logs it seems that its unable to instantiate the SearchSoapClient in the web proxy(Search.wsdl).

Is there any possible solution to resolve this issue. we have included all jar files. Do we have to any configuration in server.xml of SOA server to make the Stellent connections work..
Kindly assist regarding this issue. Thanks in advance.

I got the solution.

Java Embedding setVariableData not working - Urgent

Hi Guys,
I tried a simple HelloWord/Echo Kinda example, accessing input variable using getVariableData and assigning it to output variable using setVariable data in Java Embedding. It's throwing an error.

I am using Jdev 10.1.3.3 and SOA Suite 10.1.3.3
Thanks in adavance.

I gave up trying to reference elements, especially those that are accessed through the input and output messages and leave that up to BPEL Assigns. So my inline Java looks like this and it works in 10.1.3.3.
Hopefully the forum leaves enough of the formatting intact for you to get the idea.
/*Write your java code below e.g.
     System.out.println("Hello, World");
try{
String in = (String)getVariableData("Input_Value");
addAuditTrailEntry("You Entered: " + in);
int InvalidCharsFound = 0;
String ValidChars="0123456789.";
String FilteredChars="$ ,";
String TempChar="";
String Tempstring="";
int innum;
double inval;
innum=in.length();//get string length
for (int i=0;i<innum;i++){
TempChar = in.substring(i,i+1);
if (ValidChars.contains(TempChar)){
Tempstring+=TempChar;
else {
if (FilteredChars.contains(TempChar)){
//filtered char was found
addAuditTrailEntry("A filtered character was found such as: " + FilteredChars);
else{
//invalid chars
InvalidCharsFound = 1;
addAuditTrailEntry("An invalid character was found");
if (InvalidCharsFound == 0){
//clean number input was detected so proceed.
inval = Double.valueOf(Tempstring).doubleValue();
inval *= 100;//multiply by 100
addAuditTrailEntry("Times 100 is: " + inval);
double out = Math.rint(inval);
addAuditTrailEntry("Rounded is: " + out);
out /= 100;
addAuditTrailEntry("Divided by 100 is: " + out);
DecimalFormat myFormatter = new DecimalFormat("###.00");
String output = myFormatter.format(out);
addAuditTrailEntry("Formated is: " + output);
setVariableData("Output_Value",output);
else
// The number input was not a good clean number
setVariableData("Output_Value","ERROR the input was not a number");
catch(Exception e){
addAuditTrailEntry(e);
If you actually find this Java example that I made usefull keep in mind the Math.rint
function incorrectly rounds 100.5 to 100 instead of 101. Or in other words with this program if you try to round 100.245 it will produce 100.24. This is not a problem for what I'm using it for as I'm simply trying to correct small inaccuracies found when adding 2 currency numbers using BPEL see Bug No. 6451541
As far as the Math.rint "bug" I have found this same issue duscussed on the sun java forums and as far as I can tell someone who is mathematically brilliant (compared to me) decided that this was the correct way to round. I'm glad I'm not in school any more.
Oh the complete BPEL source looks like this (I probably should have included this instead)

BPEL: invalid namespace error with DB adapter polling and java embedding

Hello
I'm using bpel 10.1.3.1.0, and I'm experiencing the following problem: I'm am not able to use the SetTitle() function in a process which polls for records using the db adapter.
Steps to reproduce the problem:
- I create a very simple bpel process which poll for records in a table.
- I deploy it, write manually a record in the polled table and the process start.
- I can see the record picked up through the visual flow in the console
- everything looks ok and the process ends correctly
- now I add a java embedding activities just after the receive
- I set the instance title like this: setTitle("Go");
- redeploy, write a record in the polled table and the process start.
- but the process ends in error with the following message "XMLDOMException has been thrown. invalid namespace for prefix xmlns"
And there is no way to make it work. Consider:
If I put the same java embedding activity in another process, for example a simple asynchronous process which just copy the input to the output, and I run from the console, the instance title is set as I want ("Go")
If I remove the three lines from the polling process
<bpelx:exec name="Java_Embedding_1" language="java" version="1.3">
<![CDATA[setTitle("Go");]]>
</bpelx:exec>
then the process is executed correctly again. I add them again and then namespace error.
Whatever statement I put in the java embedding activity (for example a string concatenation or even just a comment I have the same result: invalid namespace for prefix xmlns.
Does anybody has a suggestion to evercome the problem? I need to set the title because its a mess to find out which instance processed a specific record.
Thanks by
Paolo

I made a lot of further tests, and I can say the problem is related only to the database adapter polling mechanism.
If I create an asynchronous process, with any kind of database activity (for example select) I can set the title normally.
If I create a process which start with database table polling, then I cannot use the java embedding.
try this:
- create BPEL empty project
- drop a database adapter service and follow the wizard:
- select a connection (I tried both oracle or sqlserver connection)
- select "poll for new or changed record"
- select any table empty or with few record inside (1 or 2)
- press next 4 times
- chose delete record after read (press next)
- chose order by "no ordering" in polling options (press next 2 times)
- now drop a receive activity on the process, and connect with the polling partner link
- drop a java embedding and write any valid java statement
- deploy; if the table is empty, write a recod in the table
- the process is instantiated, but the it fails in the --> receive <-- activity with "invalid namespace" error

Error in setDataVariable in Java Embedding

Hi All,
I am trying to write a simple java embedding----
Here is the code.
try{
String firstName = ((oracle.xml.parser.v2.XMLElement)getVariableData("inputVariable","payload","/client:JavaEmbeddingBpelProcessRequest/client:input")).getFirstChild().getNodeValue();
addAuditTrailEntry("Inputvalue is"+firstName);
String sConcatString ="Hello!!!"+firstName;
addAuditTrailEntry("OutputString is"+sConcatString);
setVariableData("outputVariable","payload","/client:JavaEmbeddingBpelProcessResponse/client:result",sConcatString);
addAuditTrailEntry("ENDING.....");
catch (Exception e)
e.printStackTrace();
All the Audit trails come in the screen except the last one, just before where i m trying to assign to the result variable.
I get some thing like this in the console:-
Error in <assign> expression :<to> value is empty at line"".The XPath expression:"" returns zero node,when applied to the document shown below.
oracle.xml.parser.v2.XMLElement@64d196
This is a simple code i was trying. This code i found in the threads only, but for me this isnt working.
Can anyone please help me to fix this prob.??
I appreciate all the time n help for this.

Here it comes:::

Java Embedding

Hi everybody,
i'm trying to use java embedding but i haven't understand a thing... for example, if i put a simple thing like
System.out.println("Hello, World");
where does i can see what i have written? there is something like a log file?
i explain what is my goal: i would like to create a very simple database on a file and i have thinked to use java embedding to write winth easy commands like println... in my database i will write 2 variables from my bpel projec like "name" "mark" .... there is an easiest way to do that?? thanks a lot

Alex,
which version of SOA Suite you are intending to use. If you very new to BPEL, I strongly recommend that you study Orderbooking demo which contains step by step information and explains bpel. If you have soa suite installed, you can find lots of samples at <soa-suite_home>/bpel/samples directory.
for you scenario, I understand, you have front-end page like JSP, and after that you want to call BPEL and then send the data to Database. Now If you are using JSP, you may need to have following steps.
1) Prepare the database table.
2) write JSP page,
3) prepare scripts to validate the pages
4) Create BPEL process which takes desired inputs. In BPEL process, create database adapter to insert the data into specific table.
5) send the control to java class which will invoke the BPEL process. You can search on "Invoke BPEL from JSP" and you will get a lot of help on that.
You may find the steps bit complex, but if you go through Orderbooking demo, that will help you to understand soa suite functionality.
