Java embedding code in BPEL 2.0 giving deployment errors

Hello,
I am using Jdeveloper and SOA 6 11.1.1.0.6 version. BPEL 2.0
When i use simple sysout in the java embedding it is deploying fine but when using XMLElement api in the java embedding it s giving deployment error.
Please suggest me how to make it work.
Please see the error message below:
Error deploying archive sca_FetchAttachments_rev1.1.jar to partition "default" on server soa_server1 [http://XXX.XXX.com:8001]
[01:04:09 PM] HTTP error code returned [500]
[01:04:09 PM] Error message from server:
There was an error deploying the composite on soa_server1: Error occurred during deployment of component: FetchAttachments to service engine: implementation.bpel, for composite: FetchAttachments: ORABPEL-05250

Hello Rolando Carrasco,
Thank for responding my question. I figure out the issue. It is because we need to import the java API's what we are using in the java embedding.
Thank you,
Raj

Coherence in SOA BPEL Java Embedding error

I am trying to use Coherence to cache message in SOA BPEL process.
The BPEL process is deployed into WebLogic 10.3.2 on SOA 11g platform.
Withing the BPEL, I use Java Embedding, try to cache a meesage on another coherence instance (Running as a server from
a different JVM). But I am getting "Storage is not configured" exception after the "Jave Embedding invoked" message.
Here is my code:
System.out.println("Jave Embedding invoked");
try{
//set localstorage to false, use remote Coherence server
System.setProperty("tangosol.coherence.distributed.localstorage", "false");
System.setProperty("tangosol.coherence.log.level", "3");
catch(Exception e) {
e.printStackTrace();
CacheFactory.ensureCluster();
NamedCache myCache = CacheFactory.getCache("mycache");
// put key, value pair into the cache.
myCache.put("Name","Test");
System.out.println("Value in cache is " + myCache.get("Name"));
I use the same code in JDeveloper, and see the message is put on the remote cache server. But when I invoke it through BPEL, I don't even see the new coherence member join the cluster.
I use the default cache-server.cmd from Coherence package to start the server.
Anyone has similar experience to share?
Thanks
George

Brian,
Thanks for the reply. For your questions:
1. A firewall between your process and the rest of the cluster.
I run Weblogic and Coherence server on the same development laptop, so no firewall here.
2. Mis/different configuration between your process and the cluster.
I did not use any customized configuration files, all configs are straight from coherence.jar.
3. A classloader issue leading to the wrong cache configuration being picked up.
Since I use the same jar in Coherence server and weblogic server, and confgurations are from the jar, so they are the same.
4. Using different and incompatible versions of Coherence between your process and the cluster.
See answer to 3.
I do not see the process from BPEL join the coherence server from the server console.
I am wondering if Weblogic server block coherence multicast messages, if that's the case, what other choices I can have to communicate to coherence server? is Coherence-extend the right direction to explore?
Thanks
George

XML Parser Error in bpel java exec code

hi,
When BPEL PM is loading processes from the deploy directory, the following exception is thrown. Any thoughts on why this XML error is being thrown ? Also, this problem is not consistently reproducible.
Thanks,
Ravikiran
bpel<Line 232, Column 72>: XML-24523: (Error) Invalid value 'NotifyFoo' for attribute: 'name'.

One more piece of information that may be relevant. There are 4 BPEL processes that are deployed (copied into deploy directory) that all have "NotifyFoo" java exec element. Is it that somehow some parser is seeing this "name" attribute "NotifyFoo" refered to in two processes as being used twice in the same process? Perhaps this is because the element is a Java code ?
Thanks,

Problem in Uploading Java mapping Code

Hi Guys,
I never work on Java mapping before, i got the code required for my progrmme in these forums.So i saved it as a text file. now i want to import that fileintomy programme as Java class. i think i have to use Netweaver Studio. what exactly i have o do it.
Thanks in advance.
Kartik

Hello Kartik,
If your code is handling the Required Mapping.Then what is you need to do is :
Create the Jar file using any Java IDE (or) use Netweaver developer studio.
Before creating the u201Cjaru201D file just make sure that the "path" of the class file in the imported archive. It should be the
same as your "package" path.
Once the class file is created, we have to create the jar file with all the necessary files. After creating the jar file, it
has to be deployed to XI.
Import the Jar file using Imported Archive in IR under Mapping Objects.
See this blog it explains how to load :
Java Mapping (Part III)
After doing the necessary setps you can test the Mapping.

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+

Java Embedding bug in SOA Suite 11g BPEL??

Java Embedding Weird XML Node Error

Ok, I am going crazy. I have a java embedding node that takes a date string in, changes it to a different format and creates another date that contains the current time. if I run this in java to code run ok and there are no issues. At the end of the java I print out the string and they are exactly what I want. The thing that is going on is when I set the 2 string BPEL variables in the java embedding, when I try to reference them the 2nd time,I get a weird node object error. I get through the first pass ok. when I try to reference Test1 or Test2 on the 2nd pass I get the error below. Its like when I set the variable currentDB2UpdateDate and currentDB2CurrTimeDate it does something to them. Instead of setting it to just the string it seems to set it to some kind of object.
I have 3 steps here. Assign -> Java Embedding -> Assign.
Assign 1 => Initialize 2 String variables to X.
<code>
<assign name="Assign_2">
<copy>
<from expression="string('X')"/>
<to variable="currentDB2UpdateDate"/>
</copy>
<copy>
<from expression="string('X')"/>
<to variable="currentDB2CurrTimeDate"/>
</copy>
</assign>
</code>
Java Embedding =>
<code>
String currentFileDate = (String)getVariableData("currentFileDate");
String currentDate = "";
try
SimpleDateFormat sdfSource = new SimpleDateFormat("MM/dd/yyyy");
Date date = sdfSource.parse(currentFileDate);
SimpleDateFormat sdfDestination = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
currentFileDate = sdfDestination.format(date);
catch(ParseException pe)
System.out.println("Parse Exception : " + pe);
try
Calendar cal = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
currentDate = sdf.format(cal.getTime());
catch(Exception pe)
System.out.println("Parse Exception : " + pe);
System.out.println("currentFileDate : " + currentFileDate.toString());
System.out.println("currentDate : " + currentDate.toString());
setVariableData("currentDB2UpdateDate",currentFileDate);
setVariableData("currentDB2CurrTimeDate",currentDate);
</code>
Assign 3 =>
<code>
<assign name="Assign_1">
<copy>
<from variable="currentDB2UpdateDate"/>
<to variable="Test1"/>
</copy>
<copy>
<from variable="currentDB2CurrTimeDate"/>
<to variable="Test2"/>
</copy>
</assign>
</code>
<code>
<bpelFault><faultType>0</faultType><selectionFailure xmlns="http://schemas.xmlsoap.org/ws/2003/03/business-process/"><part name="summary"><summary>Invalid to part type.
When performing the assign operation, the to node 2010-07-17 12:00:00 is invalid.
The node named in the error message was either null or an empty node set, and it was not an instance of org.w3c.Element.
Verify the node value at line number 819 is not null and is an instance of org.w3c.Element.
</summary></part></selectionFailure></bpelFault>
</code>
The 2nd pass to this throws the following error when trying to set Test1 and Test2 again... Its like it is setting the variable to an object and not just the string. I tried using toString() in the setVariable too and it didn't work. I don't get it.

I am also facing a similar issue.There is selection failure in assignment to local variable of BPEL .
PFB the logs :
parts: {{
summary=&lt;summary&gt;Invalid to part type.
When performing the assign operation, the to node false is invalid.
The node named in the error message was either null or an empty node set, and it was not an instance of org.w3c.Element.
Verify the node value at line number 3577 is not null and is an instance of org.w3c.Element.
&lt;/summary&gt;}
Here is the code:
<copy>
<from expression="xpath20:add-dayTimeDuration-to-dateTime($calculatednpexectime,'P200YT')"/>
<to variable="calculatednpexectime"/>
</copy>
It seems as if Oracle is not accepting the date format .
Is there some issue with local variables of new version of BPEL ??

Using Java Embedding Unzip Code and a Trigger File in a BPEL Process

Hello,
Thanks in advance to anyone that contributes with any insight. It is much appreciated. Having said that I will get to the crux of my problem.
I am currently using Oracle 11g. I have created a SOA composite application that incorporates BPEL and Java. I have the code needed to unzip and extract compressed folders. However, when this was first built out using BPEL it automatically created a web service in the "exposed service" lane and not a file adapter which I believe is needed in order to trigger the process via a start.txt file for example. Based on what I know ... this web service automatically connecting to the BPEL process was simply due to the order of operations, etc. So by creating a 'read' file adapter first and then creating the BPEL process and selecting the template "Define Service Later", it does not automatcially connect the web service to the BPEL process and it will allow me to connect a file adapter to this BPEL process instead ... great. When opening up the BPEL file I then connect a recieve component to this file adapter and configure appropriately.
Essentially, my objective in setting up a trigger to start this unzip process is due to the BPEL process before that outputs or writes the .zip folder to the same directory that I want to poll and/or trigger via a start.txt file. I can get this process to work with a webservice connecting to the BPEL process and by using a Java Embedded in BPEL file, which in turns calls the package/ class that has the java code needed to unzip.
For some reason whenever I try to use a file adapter instead of the native web service that gets created (as mentioned above) it doesn't work. It seems to build or compile just fine however, I am getting errors when I try to deploy.
Note: The Java code contains all the paths where the zip file is to be taken from and extracted to. So because this is in the code I don't need the file adapter to handle this. I just want to use the file adapter so that I can trigger the process via start.txt or something of that nature.
Thanks to anyone that has any suggestions.
Kind Regards,
Kevin

Adding a java class code in BPEL 11g

Hi Friends ,
i m doing one simple example of calling a java class from bpel ,
1. first i created a java class
2. After that in my project i imported the jar file of the same class , and i am using JavaEmbedding
for creating one object of that class and calling one method which return me the string result and finally i am setting the result in bpel variable.
the application is build successfull but when i am deploying it i am getting following error

please tell me what is the problem.

You have to use the below value there.
+2. After that in my project i imported the jar file of the same class ,+
There are 2 things, if you are not going to reuse the same code, its better to use Java Embedded component.
If you are going to reuse the same methods from the class then it make sense to import as jar file and use it.
Thanks,

How to include Java embedding in BPEL to connect with Siebel On Demand

Hi,
I am trying to integrate Siebel on Demand with BPEL using the instructions given in the Best practices page http://www.oracle.com/technology/tech/fmw4apps/siebel/ofm-siebel-blog-postings.html.
The code used in the Java embedding does not send a response back. I have increased the timeout period but still i get a time out error.
Please let me know if anyone is aware of a work aorund for this
Thanks.

There is a common approach to this problem which is a dependency repository. Various build tools address the dependency resolution problem. Most common are maven and greadle. Place your Jar file on a location you can reach from your various developement environments (eg. a share on a server in your network) Then configure your build tool to know about your repository.
A better solution that a naked net share is a nexus server, which will not only hanlde dependencies you namually placed on your share but also dependencies available on public repositories.
In your project you simply declare the (direct) dependencies of the Code you're writing. For maven you need an aditional file in your project: the pom.xml. maven (or greadle) will handle all the transient dependencies for you (as long as the pom.xml of the dependency also declares its own dependencies and those other dependencies are reachable for maven too).

Restricting actions in "Java Embedding" BPEL component

While playing around with BPEL processes in Oracle SOA Suite 11g, I found that a System.exit(1) in the Java Embedding component actually shuts down the weblogic server. Are there means to restrict similar code from executing (such as by assigning specific security policies)?
I'd assume that if the implementation of Java Embedding forks a new JVM to execute the embedded code, this problem wouldn't have occurred. Is there some way in SOA suite to specify this behavior?
Appreciate your response,
~Raman

What is the variable type of configData? if this is simple type string then you can assign the value directly else if the variable of type xsd element or message type the syntax looks as below
setVariableData("variablename","partname","xpath",data);
e.g
setVariableData("outputVariable","payload","/client:HelloJavaEmbedBPELProcessResponse/client:result",xmlData);

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);

How to encrypt file on linux using Gnupg command in Java Embedding in BPEL.

Hi All,
I am trying to invoke a command script using the java embedding in BPEL Process.I am using the below code to execute the particular command to encrypt the file :-
try {
        Runtime rt = Runtime.getRuntime();
Process pr = rt.exec(new String[] {"/bin/bash", "-c", "/u01/GnuPG/bin/gpg", "-e", "-r", "Developer","/u01/oracle/ConfigFiles/Adapter_controlDir/abc.csv"});
         int exitVal = pr.waitFor();
        String result = "SUCCESS: Process exit with " + exitVal;
        addAuditTrailEntry("result = "+result);
        setVariableData("outputVariable","payload","/client:processResponse/client:result",result);
} catch(Exception e) {
        e.printStackTrace();
String result = "FAILURE: Exception with " + e.toString();
        addAuditTrailEntry("result = "+result);
        setVariableData("outputVariable","payload","/client:processResponse/client:result",result);
The above statement does nothing. I am not sure what command i need to use to access to the command line.
When i try this particular statement from linux machine command prompt :- /u01/GnuPG/bin/gpg -e -r Developer /u01/oracle/ConfigFiles/Adapter_controlDir/abc.csv
It works absolutely fine and it creates the encrypted files also.
Please suggest , which command i need to use from the java embedding.
Please suggest!!
Regards,
Shah

I think, you can try, writing these commands into a separate shell script and call that shell script from bpel via Java embedding. However, you might not get a return response.. but you can still give a shot.
Hope it helps.

Throwing Exception in java embedding to BPEL

Hi,
My requirement is that all exceptions needs to be thrown to BPEL so that the BPEL exception handler can handle it.I am using some classes through BPEL's java embedding. So any exception in them, i wud like to be propagated to BPEL. The Exception is thrown to the java embedding activity but i am not able to throw it to BPEL after that. I have to catch and handle it there itself, else the BPEL gives a compilation error.
Can anybody please gimme a sol for this problem
Thanks
