Java activity - import

I've noticed the Java examples in the Developers guide uses class names that are not fully quailified with the package. That leads me to believe there is an equivalent of an import statement somewhere.
I have to fully qualify all class names with package info in order to compile. Am I missing something? The Developer's Guide doesn't cover this.

The answer is in the JavaExecSample.bpel that comes with BPEL.
In the header portion of your BPEL source code, put the following:
<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="com.otn.samples.javaexec.CreditCalculator"/>
This will have the affect of using import statements in your Java code.

Java Mail and Java Activator

I have problems to deploy the API's Java Mail and Java Activator
into Oracle 8.1.5 on a NT4 server.
When deploying the classes in the API's that has names beginning
with "com/sun/java..." everything works fine, but when trying to
deploy the classes starting with "javax..." I get error:
"ORA-01031 Unsufficient privileges."
The error occurs during the creation of the classes.
Does someone know why?
I have tried to unjar the jar-files, and rejar them again with
no compression, but this does not help.

Hi Mark
I wish to send email messages from stored procedure. I looked at
the "Java Stored Procedures Developer's Guide" but I am still
confused. I wrote a Java program (importing "javax.mail" package)
and then I called "loadjava": it did not work
I read this reply, but I do not understand exactly what you mean.
I am quite new to Oracle, and there are "tons" of things which I
do not understand.
Would you please explain me what I have to do to send email from
a stored procedure?
Thanks in advance, Carlo

Problem calling a EJB Java Client from Java Activity Agent

Hi,
We have a wrapper java class that calls to an EJB through a JNDI lookup. The wrapper class is called from a workflow. The problem is that the call fail with the following message error:
Error : getRemoteHome Lugar: ServiceLocator NamingException Mensaje Error: Receive timed out
Mon Jan 09 15:32:13 EST 2006 Enqueuing VIC/97513 com.tallion.tax.workflow.assessment.Update

The wrapper class has in their classpath a jndi.properties as follows:
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.provider.url=69.0.137.120:1099
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
The call just works fine when we restart the Java Activity Agent and then, after a while it fails again with the same error.
Any ideas/workaround?
Thanks.

I have a situation that is a bit similar. I have successfully used beans for storing methods used in JSPs and used by other methods in the same class as was suggested above. Now I would like to break some methods into another (utility) class since they are lower level and can be used by lots of things. They are for database operations (given a String query and String dbname, it queries and returns ResultSet for example). I want to have them in a separate class for reusability and OOP.
I am having problems calling those public static methods in the public class from my bean that communicates with the JSP. I can't compile the class that calls the method in the database ops class. I get an error like :
loginHelper.java:45: cannot find symbol
symbol : variable sqlHelper
location: class dbHelperBean.loginHelper
and when I include the package name in the call I get
loginHelper.java:45: cannot find symbol
symbol : class sqlHelper
location: package dbHelperBean
That's strange since the package of both classes is dbHelperBean and the class is indeed called sqlHelper. I tried to compile it in the same directory as sqlHelper as well. What am I doing wrong?
Thanks for any help.

Java field imported to ABAP RFC

Hello,
I'm using the following code in a User Defined Function within XI 3.0 and I'm having difficulty getting the correct "message id" imported into the RFC.
I've tried changing the data type of I_MESSAGEID. Using this message id and the following data types I get different results:
I_MESSAGEID should look like this: 4989D6DBCE5B4C85E10000000A5060AC
but when...
I_MESSAGEID is set to CHAR(32): Ó倃၏טℶ፝㓓
I_MESSAGEID is set to RAW(16): E3DF01DB7D03DB6E3ADF9E84135D34D3
I_MESSAGEID is set to String: ######n:ߞ##]4#
Here is my java code:
public String Create_ZTOR_Rec(String MsgID,String MsgDate,String MsgTime,String PONum,Container container){
String content = "";
MappingTrace importanttrace;
importanttrace = container.getTrace();
// filling the string with our RFC-XML (with values)
String m = "<?xml version="1.0" encoding="UTF-8"?><ns0:Z_UDF_CREATE_ZTOR_REC xmlns:ns0="urn:sap-com:document:sap:rfc:functions">";
m = m + "<I_MESSAGEID>" + MsgID + "</I_MESSAGEID>";
m = m + "<I_EBELN>" + PONum + "</I_EBELN>";
m = m + "<I_ERDAT>" + MsgDate + "</I_ERDAT>";
m = m + "<I_UZEIT>" + MsgTime + "</I_UZEIT>";
m = m + "</ns0:Z_UDF_CREATE_ZTOR_REC>";
RfcAccessor accessor = null;
ByteArrayOutputStream out = null;
try
// 1. Determine a channel (Business system, Communication channel)
Channel channel = LookupService.getChannel("XI","GeneratedReceiverChannel_RFC");
// 2. Get a RFC accessor for a channel.
accessor = LookupService.getRfcAccessor(channel);
Any Ideas how I can convert this message id in Java to import it properly?
Thanks,
Matt

It is a good document and I noticed the link to Help.sap.com explained why writing to/updating a table through java mapping is not a good idea but in this case I do not have an option.
I was unable to find anything to explain why all the other strings are processed in the RFC but the message id gets garbled.
When I test the RFC manually it works properly. When I attach the message id to the outgoing document it appears correctly. So the error appears to be happening here:
// 3. Create a xml input stream representing the function module request message.
InputStream inputStream = new ByteArrayInputStream(m.getBytes());
// 4. Create xml payload
XmlPayload payload = LookupService.getXmlPayload(inputStream);
// 5. Execute Record Create.
Payload result = accessor.call(payload);
InputStream in = result.getContent();
Does anyone know how I can get the correct message id into my RFC?
Thanks,
Matt

Hi ,
In your java project frm jdev..right click and choose general and then choose deployment profiles and then choose Jar ..and then give some appropriate name(abc) and then click ok.
Then under resources file u get a abc.deploy file right click and say deploy to jar ..u will find the jar in that director.Now include this jar in your prjct libraries.
have a look at the link http://niallcblogs.blogspot.com/search/label/embedded%20Java

Wait for Java Activity

Hi All,
I have a Java Activity inside the BPEL.
Now, this Java Activity gives a call to an external Web service using Apache Axis and it takes approximately around 30 seconds for the webservice to complete and return the response.
However, in the meantime by BPEL flow doesn't wait for the java response and goes ahead.
Any idea how can I make my BPEL flow wait until the java activity is completed and hence, return the response back to the BPEL.
TIA.

Hi,
Java Activity gives a call to an external Web service using Apache AxisAny particular reason to not use the regular BPEL web service call?
However, in the meantime by BPEL flow doesn't wait for the java response and goes ahead.AFAIK, this is not BPEL normal behaviour, so I imagine that this "fire-and-forget" behaviour is actually inside the java code...
If that's the case, you either should change the way Axis is calling this external WS into the java code, or use a BPEL external web service call.
Cheers,
Vlad

NWDI Activity Import fails to deploy to runtime portal environment

Recently, we have been having trouble migrating activities through our tracks and having the activities deploy into our runtime portal environments.
The activity imports complete, and the CBS does a successfuly build, but the changes fail to appear in the Portal Runtime Environment.
It varies across all activities, and tracks.
Also, sometimes we can go into the CBS and initiate a build on the desired development component, which will then deploy. Sometimes this works, sometimes it does not.
Anyone have any ideas?
Please feel free to contact me at my email address below. Thanks for the help.

Rajat,
   Thanks for replying.
   Unfortunately, the problem persists after we restart the SAP Services on both the DTR and CBS servers. Clearing out memory, etc... doesnt seem to do the trick anymore. Oncec the CBS comes back up, and we initiate a build on the DC, changes still are not reflected in the portal runtime.
   Are there any cache settings on the Portal itself that handle caching of JSPs, settings that handle when JSPs get recompiled, or any other settings you can think of?
Thanks.

But according to the user of my application ,im allowed to use only datasource to get the workflow database connection.
Can any one please let me whether there is option to run java activity listner using Workflow database as datasource.

Hi,
I am using integrated web logic server. Do I have to create JDBC connection in Integrated Weblogic Server? If yes, then how come it was working earlier and stopped working suddenly.
Just to try out, I have created JDBC with a name soademo (As mentioned in bc4j.xml) in Integrated Weblogic Server but didn't worked.
I will send you sample java class for your reference.
public class TestClient {
    public static void main(String[] args) {
        String amDef = "com.moj.model.AM.AppModule";
        String config = "AppModuleLocal";
        ApplicationModule am =
            Configuration.createRootApplicationModule(amDef, config);
        ViewObject emplist = am.findViewObject("EmployeesView1");
        emplist.setWhereClause("first_name = :p_firstname");
        emplist.defineNamedWhereClauseParam("p_firstname", null, null);
        emplist.setNamedWhereClauseParam("p_firstname", "Smith");
        emplist.executeQuery();

            System.out.println("Last Name " + emp.getAttribute("LastName"));

View Compilation Errors in Embedded Java Activity

Hi,
Is there any way to see the compilation errors in the Embedded Java Activity in the BPEL.
Thanks,
Ajay

Hi,
Exceptions are automatically converted to BPEL faults and thrown back in BPEL.
But to see some errors , one can use try catch block with audit trail entry in catch block like :
try {
catch (Exception e){
addAuditTrailEntry(e);
I have not used this so not sure if this will work.

Fast return from Java Activity Agent

Hello,
long ago I had defined some workflows using the Java Activity Agent. But now I have to create a new flow with a lot of very short activities, and I want to return control to the workflow engine as fast as possible when they complete, without waiting for the next call to background processing. Is there any known best practice to achieve this? I have tried to enqueue calls to the background engine in my java classes, but this doesn't seem a solution.
Thank you in advance,
Antonio

Hello,
I didn't post my solution because it's very hackish, though it has dramatically improved my execution time.
But to answer your curiosity...
I have added a listener to the inbound queue, thus replacing the loop to call the background engine with calls synchronized with inbound messages. Additionally I call the background engine every 30 seconds, just in case, and so that the loop exit condition is checked.
So, here's my basic listener/background handler:
DECLARE
        q_agent sys.aq$_agent;
        wf_agent sys.aq$_agent := sys.aq$_agent(NULL,'OWF_MGR.WF_INBOUND_QUEUE',0);
        v_tab_agents DBMS_AQ.aq$_agent_list_t;
BEGIN
        v_tab_agents(1) := wf_agent;
       WHILE( < ANY CONDITION TO STOP PROCESSING ... > ) LOOP
         dbms_aq.listen(
         agent_list => v_tab_agents,
         WAIT => 30, /* in seconds, may be   DBMS_AQ.FOREVER */
         agent => q_agent
         owf_mgr.wf_engine.background;
     --    DBMS_OUTPUT.PUT_LINE('Date: ' || TO_CHAR(SYSDATE,'yyyy/mm/dd hh24:mi:ss' );
          END LOOP;
END;
