Hi,

it's very useful to know java in XI.

Some components run on java like Integration Repository and Integration Directory.

Most useful is java for writing mappings in java or you can write user defined functions in message mapping.

Here you will get a good overview about the components of XI:

Hi kasi rajesh ,

>> I need how java is useful in XI.

If u r a java developer , u may be having sound knowledge on JDBC,XML,XSLT..etc which u come across in XI. The messages will be in XML format which r exchanged b/w systems.

JDBC is one method thru which we can Xchange messages.

And also an important thing , we need UPLOAD JAVA CODE into XI to achieve certain functionality.

So, it is advantageous 2 u.

Check the following websites which will answer u'r question.

Java is very useful in XI.

Since you are having a background or Java you will better do coding for Java Mapping, Java Proxy.

Even UDF during the mapping.

Even you can participate in Adapter and Module development area.

Hi,

XI is majorly developed in the java language and few components developed in the ABAP.

We have some predefined functions in XI Graphical mapping, but some times it may not suit to our requirement on that time according to our requirement we can write the java code.

All the Converstion programs are written in Java Code.

JAVA PROXY

1. RFC/BAPI

2. IDoc

3. Proxy

By using these ways we can connect to the R/3

If there is no IDoc or RFC is suitable to our requirement then we go for Proxy,

Go to ABAP and execute the SPROXY T-code

select the msg interface --> right click --> java proxy generation.

Java proxy require 3 jar files that are

1. aii_proxy_xirt.jar

2. aii_utilxi_misc.jar

3. guidgenerator.jar

Mainly for writing the UDFs and in Proxies we can use the java,

Hi,

SAP XI is developed using both ABAP and Java.

Java is used in XI to work with User Defined Functions (UDF) and Java Mappings.

UDF is like a sub-routine which is used in mapping logic. Also Java Mapping is a kind of mapping used in XI, where the mapping logic is to be written in Java language.

Integration Directory and Integration Repository, SLD are developed in JAVA.

Java is useful in UDF, java mapping, adapter module, java proxy development.

runtime environments

String headerField;

java.util.Map map;

// get runtime constant map

map = container.getTransformationParameters();

// get value of header field by using variable key

headerField = (String) map.get(key);

For example, to read the message ID from the message header, the variable key must have the value MessageId and not MESSAGE_ID.

HI Rajesh,

In XI Java is very useful. There is Adapter Engine is exist its

run on Java Runtime Environment. Adapter Engine convert Different formats into XML Adapters are used in both sender and receiver side.

Adapter Engine is in J2EE stack

Integration Engine is in ABAP stack.

Some inputs-

All the Converstion programs are written in Java Code.

Whenever you are mapping source and target values you have to use java code. If you use Graphical mapping it internally convert to java code.

Thanks,

RamuV
