Calling package from java using JNDI properties

Hi there,
I have created an interface to transfer data from oracle to JMS XML Queue. It is inside a package and have generated a scenario.
The scenario works well when executed from the ODI designer. When I execute it from java it throws an error. The error is
java.sql.SQLException: Cannot load connection class because of underlying exception: 'javax.jms.JMSException: Cannot create the initial JNDI context
Is there any ways to set the JNDI properties, (any set methods for ODIConnection object)
Cheers

Are you serious with that question? Did you try to build the web service client before? Because this is exactly the same. Try to find "building web service clients" instead "Calling BPEL from java". By default (probably) every BPEL process has both WSIF and SOAP end points, just use correct WSDL address.

Calling BRM from UDF using JNDI lookup with @EJB annotation

Hi Experts
I am trying to implement a UDF to invoke my BRM Rules set via JNDI Lookup instead of a SOAP Channel lookup.
I have had a look at the following links/docs:
Calling BRM from UDF using Public API
http://www.gleanster.com/system/resources/W1siZiIsIjIwMTIvMDgvMDcvMjAvNDcvNTAvNDMvVGhpbmdzX1lvdV9TaG91bGRfS25vd19hYm91dF9TQVBfTmV0V2VhdmVyX0JSTS5wZGYiXV0/Things%20You%20Should%20Know%20about%20SAP%20NetWeaver%20BRM.pdf
For item 1 above, the example looks really good, but it doesnt explain how I get access to the following required imports from my UDF:
import com.sap.brms.qrules.ejb.*;
import com.sap.brms.qrules.engine.AbstractProject;
import com.sap.brms.qrules.engine.RuleEngine;
import com.sap.brms.qrules.engine.RulesetContext;
import javax.ejb.EJB;
The second document is really good as well, but I could not figure out how to get it to work from my UDF.
So, can anyone help me to understand specifically what is required to get this to work?
Is is possible to invoke the rule set from my UDF?
How do I give my UDF access to all the required jars/imports?
I have manage to create a new DC (Development Component) with a public part and this enables me to get my code to compile on my local PC but I am not able to activate it due to the server not having access to the same java packages as my local copy.
Any help would be greatly appreciated.

You resolve the dependency by importing the required jars with using the dependency tab for the mapping program.
As stipulated before, I have managed to resolve the dependency issue but I have now getting the same error as in the forum: Calling BRM from UDF using Public API
The specific error is:
com.sap.engine.services.cross.PortableRemoteObjectContainer.narrow(PortableRemoteObjectContainer.java:238)
Has anyome manage to get invoke a BRM Ruleset using JNDI?

Calling C from Java. C takes in a command line input

Hello,
I have created some basic JNI programs, in which the java file calls the C files. The way I could do it was directly calling the functions in the C files, which I needed. Now I am trying to call a C file from Java, and the C files takes in a command line argument after being compiled.
Also after compiling the C file, it produces an exe. I cannot change the C file and also want to call it from Java using JNI (as I want to later put all this into a jar and jnlp file and put it on webstart).
If anyone can help me on how to call the compiled C file and how to send in the input as a command line argument I would greatly appreciate it.
Thanks
Nick

Now I know how to create a C wrapper file and a Java file in JNI format. Does this mean you want to run the exe files by calling the main() method through JNI. Yes you can do that BUT you will need to turn your exe file into a dll and then write a JNI wrapper to act as a bridge between the Java and the dll.Yes. Thats exactly what I want to do. I want to call the C files through JNI. But what I am asking is, how do I send in the input which is originally sent in as stdin? And also what are the steps to follow if I want to call a main method of the C files in the JNI.
Up till now I have been using JNI to call functions from the initial C files from the C wrapper file. But now I want to call the .exe file by sending it a command line input. Or if you can suggest a better method that would be great.
You can execute an exe file using ProcessBuilder then there is no need for a JNI wrapper. You must read the 4 sections of [http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html|http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html] and implement ALL the recommendations. Failure to do so will cause you much grief.
You could achieve the same result but using a lot more code and a hell of a lot more effort by invoking the exe executables from JNI code that invokes the 'C' exec() library. Just thinking about that approach makes my eyes water!
Well if I just use the exec() library I can do it, yes thats ture. But I wasnt sure if I did that, and then put this on Java Web Start, if non PC users can access it or not. If macs, and linux machines can access this even If i use exec, then my problem is solved.

Calling a PLSQL package from java

Hi All
I have a problem calling a package from java. I have to pass a Date to the package which is a String in java.
How can I typecast it to the PLSQL Date from a java String.
Here is my below code for reference. The below code does not works because of typecasting problem.I tried to_date() also in java, but it is not working.
cstmt=connDbConn.prepareCall("{call pkage.PACK1(?)}"); cstmt.setString(1,"01-JAN-2009");

How can I typecast it to the PLSQL Date from a java String.That datatype in Oracle contains a date and time component.
Thus you should consider exactly what storing the date only component means in terms of the timezone that the Oracle server is using.

Duration of an Abap Function call from Java using Jco3

Hi guys!
I would like to use this discussion to get some refernces of the duration Timespan of an RFC call from Java to SAP. At the moment, i need at last about 200ms to call the Abap function. I'm just using one simple import and export parameter (so no deep structures). I think that the reason for my poor performance is, that the Java Tool and the SAP instance are not in the same network. So, i hope some of you have some data, how fast an RFC call from Java using Jco can be executed.
greetings, Hannes

Hi Hannes,
I think you have already got the answer to your question - the network set-up you have is probably the bottleneck. Whenever I've worked with Java <-> ABAP and they are in the same network, I've had no performance problems at all.
Does your RFC contain any complex logic or business processes? Are you able to try and call something that does nothing, say it just accepts an input string and returns it straight away as an export. Do you have any scope for testing with your Java tool on the same network as the SAP system?
Cheers,
G.

Call ESB from java or unix

Dear All,
Due to project requirement, I have a customer who wants to call ESB from java/unix
i am aware of java calling BPEL but I have never seen a java calling ESB ?
does any body about it ?
Is it possible ?
Appreciate your response.
Best Regards
Arc

Hi, for BPEL there is a really good API to invoke processes externally. For ESB there is not (as far as I know). But each ESB process is just invokable like any other web service. So it would be an option to use javax.xml.rpc package and create Service and Call objects. You can then make use of DII (Dynamic invoking) and there is no need to specify parameters as long payload for the ESB process is valid XML for the Routing Service.

Using jndi.properties with weblogic 6.1

Apologies if this is a basic question - I am new to Weblogic.
I have successfully got a test EJB working with Weblogic 6.1 using a properties object to set up my JNDI InitialContext.
In the weblogic examples I've downloaded it says you can also use a jndi.properties file to do this. I have set up a jndi.properties file, which is in the classpath for my class calling the EJB. But when I do my jndi .lookup("ejbname") I get the error:
javax.naming.CommunicationException: Can't find SerialContextProvider
The weblogic documentation at:
http://e-docs.bea.com/wls/docs61///rmi_iiop/API_rmi_iiop.html
refers to using jndi.properties and says to look at:
http://edocs.bea.com/wls/docs61/jndi/jndi.html
But at this page there is no mention of the jndi.properties method.
I'd be grateful for any suggestions - in particular whether it is possible to use this method of configuring the JNDI setup.
I'm running wlserver6.1 on a Windows 2000 PC, using JDK 1.3.1
My jndi.properties file looks as follows:
java.naming.property.names=java.naming.factory.initial,java.naming.provider.url
java.naming.factory.initial=weblogic.jndi.WLInitialContextFactory
java.naming.provider.url=t3://localhost:7001

It is not WebLogic-specific. See
http://java.sun.com/j2se/1.3/docs/api/javax/naming/InitialContext.html

Calling Serializer from Java

Hi,
I am calling xsql from Java.
Can I set FOPserializer with help of oraclesql like i can set other attribute of xsql.
e.g
OracleXMLQuery ors = new OracleXMLQuery(conn, selectStmt);
ors.setRaiseNoRowsException(false);
ors.setSkipRows(skipRows);
ors.setMaxRows(maxRows);
an example would be helpful.
Thanks in advance
Raju

The FOPSerializer (and the concept of serializers in general) is a feature of the XSQL Pages Framework. Your code example here is using the XML SQL Utility's OracleXMLQuery class. To use XSQL programmatically, you should use the oracle.xml.xsql.XSQLRequest class, documented in the XSQL Online Documentation
hope this helps.

               // TODO: handle exception
I tried calling ant from java. But the problem is that, i am not sure how to get the handle of error & input stream from this.
I also need to know how do I kill the ant executable if there is some kind of exception like ConnectionTimeOut or is there any some kind of timeout mechanism.
Earlier i was calling ant as an external process like Process P = new Process(), where p.execute("ant.bat xxxxx"). I used to get the error & input stream from the process itself.
Please help!!!
thanks

A better approach would be to use the classes provided in Ant. The API documentation for Ant has all the necessary information.
The sample code would look like:
Project ant = new Project();
ProjectHelper helper = new ProjectHelperImpl();
ant.init();
helper.parse(ant, new File("build.xml"));
ant.executeTarget("clean");

Need help in retrieving attributes from LDAP using JNDI

I am trying to retrieve attributes from LDAP using JNDI, but I'm getting the following error when I try to run my Java program.
Exception in thread "main" java.lang.NoClassDefFoundError: javax/naming/NamingException
I have all the jar files in my classpath: j2ee.jar, fscontext.jar and providerutil.jar. The interesting thing is that it gets compiled just fine but gives an error at run-time.
Could anyone tell me why I'm getting this error? Thanks!
Here's my code:
import javax.naming.*;
import javax.naming.directory.*;
import java.util.*;
import java.io.*;
class Getattr {
public static void main(String[] args) {
// Identify service provider to use
Hashtable env = new Hashtable(11);
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
// user     info
String userName = "username";
String password = "password";
// LDAP server specific information
String host = "ldaphostname";
String port = "portnumber";
String basedn = "o=organization,c=country";
String userdn = "cn=" + userName + "," + basedn;
env.put(Context.PROVIDER_URL, "ldap://" + host + ":" + port + "/" + basedn);
env.put(Context.SECURITY_PRINCIPAL, userdn);
env.put(Context.SECURITY_CREDENTIALS, password);
try {
System.setErr(new PrintStream(new FileOutputStream(new File("data.txt"))));
// Create the initial directory context
DirContext ctx = new InitialDirContext(env);
// Ask for all attributes of the object
Attributes attrs = ctx.getAttributes("cn=" + userName);
NamingEnumeration ne = attrs.getAll();
while(ne.hasMore()){
Attribute attr = (Attribute) ne.next();
if(attr.size() > 1){
for(Enumeration e = attr.getAll(); e.hasMoreElements() ;) {
System.err.println(attr.getID() + ": " + e.nextElement());
} else {
     System.err.println(attr.getID() + ": " + attr.get());
// Close the context when we're done
ctx.close();
} catch(javax.naming.NamingException ne) {
     System.err.println("Naming Exception: " + ne);
} catch(IOException ioe) {
     System.err.println("IO Exception: " + ioe);

That doesn't work either. It seems its not finding the NamingException class in any of the jar files. I don't know why? Any clues?

How to call xml from java

Hi
I want to use xml for updating files in an existing jar . so i want to call xml from java code and then come back to java code and do the remaining work in java code, pl guide me how to do this . what APIs are helpful for this regard
Thanks

You can't update files in a jar. Even if you could, you wouldn't use XML for that. You don't call XML. XML is not a programming language. So, basically your entire question is misguided.
