Java or C# Connector

Hi,
is it possible to write a Connector to SAP without having NetWeaver installed, using C# oder Java as language?

just looking for an opinion as to whether java or c# is the best language
or put it another way where is the money making opportunitiesThese are completely different questions.
C# is probably the better language, but it doesn't have so many runtimes on different OSes, doesn't have as mature an implementation, as extensive a set of libraries and has some errors in its api wrt to operator overloading (eg (list + 5) + 5 != list + (5 + 5)).
As to making money, I'm an engineer not a banker.

what's the problem?
ok, i am using a mysql db und using the driver mysql-connector-java-5.1.8-bin.jar....
i improted this jar file like this run -> run configuration -> classpath -> add external jar....
pls help me

That looks like it might be a binary-distribution JAR that you should unjar. The actual JAR for the classpath is probably inside it.

Sun Java System Directory connector cloning on OIM 11g R2

Hi all,
we successfully installed the +"Sun Java System Directory (9.0.4)"+ connector on OIM 11g R2 and it is properly working.
We need to clone the LDAP Resource Object in order to execute provisioning to different ldap instances,
but under "Connector Management" web console is not possible clone this connector; it's possible for example for Active Directory resource object but not for LDAP.
How we can clone the connector for LDAP?
Thanks a lot,
Ettore F.

Hello Rajiv,
thank for your help.
I figured out how to clone a connector, even if the resource object is not shown under "Connector Management".
It's enough to click the "Clone" button and providing the original xml file, of the resource object then you can proceed with the cloning of the connector in 12 steps as the wizard shows.
Bye,
Ettore F.

Java Mysql Connector

Hi everyone,
I started to work on JDBC but i have a few questions about the mysql connector.
I downloaded the .zip file and unzipped it to my desktop. Now i have a .jar file , a few folders , a installation guide and a read me file. But i couldn't understand the exact installation.
First of all where do i have to place this files? In which directory? I have a mysql database installed. But only the guide say is "calling the class.forname() function!"
I have no idea , what to place inside the forname function and where to install the connector files!
If u could tell me step by step i'll be really appreciate. Thanks for your helps.
Waiting for your answers :)

Let's see...
C:\Java\AppServer\jdk\bin\javac.exe is "javac
1.5.0_06"
.... That's the complete Java EE 5 SDKNo, javac.exe is part of Java SE. You have to have it for Java EE, of course. This version should match that of java.exe. Why does it not?
C:\Java\bin\java.exe is java version "1.5.0_08"How is it that the versions of javac.exe and java.exe don't match? You're making a mess here.
c:\MySQL50\bin\mysqld.exe is Ver 5.0.22-community
for Win32 on ia32 (MySQL Community Edition (GPL))Very good. Can you connect to MySQL using its client?
I've got copies of mysql-connector-java-5.0.3-bin.jar
all over the shop including:This is wrong. Don't have them "all over the shop".
C:\Java\lib\mysql-connector-java-3.1.13Wrong. Remove it.
C:\Program Files\Java\jre1.5.0_08\lib\ext //how the
flock did that get there?Didn't you say that you put it there? Wrong. Remove it.
C:\Program Files\Apache\Tomcat5.5\common\libCorrect. Leave it there.
C:\Program Files\Apache\Tomcat5.5\shared\libWrong. Remove it.
C:\Program
Files\Apache\Tomcat5.5\webapps\krc\WEB-INF\libPossibly wrong. Remove it.
You should have that JAR in one place from the point of view of your web context.

.jarTomcat ignores that CLASSPATH. It does you no good at all. I don't have a system CLASSPATH on any machine I use.

my code is the same as yours above except for

corlettk: oh yeah.. and mysqld is installed as a
service, which is running. tomcat isn't running, it's
not required for this test.If you run this test on the command line, you'd better be using the -classpath option to tell the JVM where to find the MySQL connector JAR. The JVM ignores your system CLASSPATH, too.

Recommendation of plugin for Java Exchange (or IMAP) connector.

Hello,
We have been using Moyosoft as a Java to Exchange connector. We have been having issue with a few of our data feeds coming through this avenue. I was just wondering of anyone in this forum could recommend a different approach. At present we.
1. Have datafeeds come to an email box.
2. Moyosoft scans email box and extracts datafeed into our system.
Is there other solutions.
Thanks,

However far as I can tell that has nothing to do with JDBC - which is the point of this particular forum.
We have been having issue with a few of our data feeds coming through this avenue. I was just wondering of anyone in this forum could recommend a different approach. At present we. In terms of a forum that might provider alternatives one of the JEE forums or just the main Java one might suggest alternatives.
One alternative of course is to write your own interface either JNI or a server to which you use TCP to communicate in java (actually I am pretty sure exchange already has a TCP interface so all you need to do is implement that in java directly.)
Or maybe buy the source code from that company and figure out the problem.

Now my big problem. At the line doc.checkSyntax throws the Java-program the following error:

     at connector.SapOrderManager.sendSapOrders(SapOrderManager.java:46)
     at connector.SapOrderManager.main(SapOrderManager.java:55)
I think the reason is, that the segment "Z1KGSPOS" lies in the wrong HierarchyLevel. In the Metadata which i get from the Sap-Server, it has to be set in Level 2. But my Java-programm puts it always in Level 3.
I think the problem accrues at the marked position in top java code. But i don´t understand whats the reason for!!!
Why did the function root.addChild(...) put the segment in Level 2 and not as desired in Level 1.
I hope anyone of you could help me!!!
Thanks from Germany

Hi Stefan,
I'm not sure I understand your problem; since I have no clue about your IDoc definition, my answer is based on ORDERS05, which might not be appropriate in your case.
Segment E1EDK14 is level 2 and not level 1; check out the definition of your IDoc. From your coding I see, that you add your custom segment Z1KGSPOS after E1EDP01. E1EDP02 is on level 2, so your segment should end up on level 3. So far so good.
Where did you place your Z1KGSPOS segment? Natural choice would be below the E1EDP01 segment, as standard SAP defines all other item segments that way. If you did that then the syntax error is caused by first adding all E1EDP01 segments and then adding the Z1KGSPOS. I guess you might've just misplaced your closing brace for your while loop.
Hope this helps, harald

Thanks duff,
The driver seems to be found
when I run
public class t {
public static void main (String[] args) {
try
System.out.println("Hello, world!\n");
Class.forName("com.mysql.jdbc.Driver");
System.out.println("MySQL Driver Found");
catch (ClassNotFoundException e)
System.out.println("MySQL Driver NOT Found");
e.printStackTrace();
I feel somehow ive been focusing in the wrong side of the problem due to my ignorance in Java. Please help me to understand, the reson for which ithe runtime was telling me that there was an unhandled exception was because it is a requirement to handle all exceptions of this kind? why wouldnt it cmplain if I jst did the hello world without any exception handling, maybe because it is a requirement in the Class.forName...
the other question is, is the message I was obtaining completely independent of the fact that the class was or was not found?
Maybe, I should go with these questions to the newbies forum...
thanks

Why is Java startup so slow?

Does anyone know why Java startup is so slow? Compared to other interpreted languages like Javascript and Perl, they run much faster. And can someone get technical with me? (But without pointing me to the JVM specification, which I don't understand.) It use to take longer for me to load Mozilla0.9 than a Java applet, but now Mozilla1.3 loads faster than a Java applet.

"Connector" is a rather ill-defined way of describing
it, which is why I chose the word -- to easily deflect
further inquiries to quantify. ;>
In a slightly more specific way, on start-up JVM needs
to (not necessarily in order, 'cause I don't know the
exact order) at the very minimum:
1. Allocate memory.
2. Query OS for a minimal set of needed facilities.
3. Allocate memory. Allocate allocated memory
(internally, for use by itself and the application).
4. Map the OS facilities to Java facilities. (This is
what I meant by "connectors").
5. Allocate memory. Allocate allocated memory.
6. Set up the internal control -- security managers,
thread scheduler, gc, classloaders, calling stacks,
virtual lookup tables, etcetc.
Some of the above don't apply to applets.
Thanks for the tip on 1.4.2beta. I'll give it a try. I
assume you meant startup speed?All this is almost instant you realize. The real time it takes to start your program is that it takes much longer for Java classes to be loaded.
The startup time is proportional to the number of classes you need to load to get your program running. If you only are writing a simple, console based java program the startup time will be much less then if you load a Swing application. Swing by itself is a huge number of classes, and then you have to load your classes. So it can take awhile.
All the things you mention, every program has to do and the code that the JVM uses must be written in C or some other systems language.
One reason at least on my machine that java startup is slow is that I have a slow hard drive. On my home machine, java is much faster around twice as fast to startup, but the processor and ram are not twice as good. I think that it's because the hard drive is faster. Because most of the time it's waiting for data from the disk and the Java enviroment has the disadvantage that it's very large on disk.

Installing JAVA API

Hello MDM Experts,
We are implementing SAP Netweaver MDM 7.1 For our customer, I have installed MDM On Windows systems and connected to SQL Database. Now MDM Developer team wants JAVA API Needs to be installed and configured.
I dont see any documentation specific to this installation on portals. Can you please share your experience?
I have the below understanding
Since MDM JAVA API Needs to be integrated to J2EE Engine, I will install J2EE Engine and deploy JAVA API Libraries in to it. once that is done Install MDM Connector using JSPM and Install NWDI on Developer machines.
Am i correct? Can some one please suggest me how i can achive this? I Really appreciate your help
Thanks,
Ravi

Thats is correct. for more detailed info , please follow the steps
Deploying the Java API and Connector Using JSPM:
Use For deployment of the Java API and MDM Connector, use the SAP Java Support Package Manager (JSPM) tool.
Procedure
1. Copy the SCA file in the JSPM inbox folder.
2. Open and logon to the JSPM tool.
3. Deploy the Java API and Connector or apply the support package as follows:
Deployment of New Software:
First Step:Select Package Type
a. Select New Software Component.
b. Select No NWDI Control.
c. Click Next.
Second Step: Specify Queue
Select MDM_JAVA_API
Third Step: Check Queue
Fourth Step: Deploy Queue
When the deployment is complete, the deployment status is displayed in the status tab.
If the deployment was successful, the wizard advances to the Completed step.
Fifth Step: Completed
Apply Support Package:
First Step: Select Package Type
a. Select Single Support Packages.
b. Select No NWDI Control.
c. Click Next.
Second Step: Specify Queue
Select MDM_JAVA_API
Third Step: Check Queue
Fourth Step: Deploy Queue
When the deployment is complete, the deployment status is displayed in the status tab.
If the deployment was successful, the wizard advances to the Completed step.
Fifth Step: Completed
4. Exit the JSPM tool.

Calendar Built in Syncml support or Free Connector

Hello,
Since we are facing a lot of bugs with the Sun Java Com Sync Connector i'am looking for a (better) synchronization tool (too many duplicates events after sync, compatibility problems, etc.)
It seems only synchronica is providing a JES connector for SyncML synchronization.
Do you know if there is a Syn4J(funambol) connector or any other "gateway" or connector that works well with JES Calendar ?
Regards

mysql-connector-java-5.0.4-bin.jar is in C:\Program Files\Java\jdk1.5.0_04\jre\lib\ext\ and Classpath and Path are OK.
any idea how to resolve this?
ps: i also have a small class that was used to test driver installation and it works just fine

You have to put the driver in the right place for your Servlet engine. You haven't done that yet. And your outside program does not show you otherwise.

What is the difference between driver and connector?

Hi for me I am not able to distinguish the both. looks same. If same why two terms? if not what is the difference? Thanking you all in advance.

I am not expert at all, but here is what I found.
The JDBC (Java Database Connectivity) Connector is a program that enables various databases to be accessed by Java application servers that are run on the Java 2 Platform, Enterprise Edition (J2EE) from Sun Microsystems. The JDBC Connector connects an application server with a JDBC driver. The Connector allows driver vendors to package drivers so that they will be plug-and-play with J2EE applications and enables application server vendors to allow third-party JDBC drivers to be used with their products. From what I understand a driver sits between a specific database and an arbitrary application.
A connector sits between a driver and an application server. I am not knowledgeable enough to explain more,
but I am sure the use of the two terms is intentional and not a mistake.

Generic LDAP Connector

Hi,
do we have in OIM such as a Generic LDAP connector to connect
LDAPs like OpenLdap?
Thanks.

The traditional solution to your problem is to take the "Sun Java System Directory" connector and customize it. All the LDAP based connectors are based on JNDI so they will work fine with any LDAP v3 server.
I seem to remember that there was some talk of LDAP support in the generic technology connector framework but it doesn't look like the support is there in 9.1.
Best regards

Configure Java Message Service Resources from java.

Hi!
I need to create, edit and delete JMS Resources from java,- but I can't find any documentations about this issue.
I hope someone can point me to the right direction.
Regards,
Ixxi

Hi!
I'm attending to use Sun Application Server 8.1.
I need to be able to configure all the JMS Resources using java - all the JMS commands you can do through the asadmin application.
To minimize numbers of administrator interfaces to maintain our system, it would be best if we could access the Sun Application Server through java - and not using the asadmin command line / browser interface.
e.g. command to written in java :
asadmin> create-connector-connection-pool ...
