It's official! The Java Veterans envy the n00bies

The developer productivity features in the upcoming Java SE 7 release (object comparison, file system monitoring, and concurrency) are enough to make a Java veteran envy the Java newbies.*
Really?

How to get the java code of the message mapping

how to get the java code of the message mapping,
I mean to ask how to get the background java code of the message mapping(graphical mapping).
And where to view it?

Hi Satya,
The JAVA code for graphical msg mapping is in below folder:
\usr\sap\<SID>\<DVEBMGS10>\j2ee\cluster\server0\temp\classpath_resolver
Here all the mapping jars are there in this folder.
Just decompile these jars and you can see the code.
Thanks,

How to view the java code of the message mapping,

Hi Experts,
how to view the java code of the message mapping,
how to get the background java code of the message mapping(graphical mapping).
And where to view it?

Hi sowmya,
Open any Message mapping in IR. Press CtrlShift0(zero) to open a new menu.
There you will find an option "Is Java Source Code Available?"
There will be an export button nearby. Use it to get the code.
Open it in a zip , you will see the hide java code.
The JAVA code for graphical msg mapping is in below folder:
\usr\sap\<SID>\<DVEBMGS10>\j2ee\cluster\server0\temp\classpath_resolver
Here all the mapping jars are there in this folder.
Just decompile these jars and you can see the code.

How can we install the Java Plugin from the html page

Hi,
I am using java plugin 1.3.1_02 for my applet pages.
How can I install that plugin in the client machine without installing manually.
I used,
<OBJECT classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
width="600" height="400" align="middle"
codebase="http://java.sun.com/products/plugin/1.3/jinstall-13-win32.cab#Version=1,3,1,2">
<PARAM NAME="code" VALUE="SignedAppletDemo.class">
<PARAM NAME="archive" VALUE="SSignedApplet.jar">
<PARAM NAME="type" VALUE="application/x-java-applet;version=1.3">
</OBJECT>
But it is downloading java plugin 1.3.1_03.
Can anybody help me
Thanks & Regards
Raja

Using object tags is the correct way and only way to download the plugin and let the client decide whether he can download it r not. There is no way to install automatically
I dont think there is a way to install automatically without a user intervention coz, it can open the floodgates for potential hackers.
Can u cite an example about which programs can be installed automatically and why do u want the plugin to be installed automatically?

How to obtain the Java environment in the already loaded dll

Hi all!
I try to implement a client GUI in Java. I load the static (c++) dll from the Java code, this work fine. But, I want to call also from the loaded dll to the client GUI, make a two-directional communication. How can I obtain the valid environment pointer in the c++ code?
Can you please help me?
Thanks very much

There is a method that returns the environment.
But, I want to call also from the loaded dll to the client GUI,In response to what? If a thread then you have to also register the thread.

How to pass the java object into the spring controller

Hi Friends
When I hit the url at the first time my call goes to the spring controller and sets the userDetails objects in the modelAndView.addObject("userDetails", userDetails.getUserDetails()) and returns the userDetails.html page. if I click any link in the same page i want to pass same (userDetails) object thru javascript or jquery and calls the another(controller) method and returns the same (userDetails.html) page.
It means how can i pass the java object thru javascript or jquery and calls the controller. if i get the same object in my controller i can avoid calling the db again. please help me out to resolve this issue. i am tired of fixing this issue.
Regards
Sherin Pooja

If you want to avoid calling the database again then cache the data.
However before you do that make sure that calling the database, in the context of YOUR system, is going to be an actual problem.
For example there is absolutely no point in caching a User object when only one user an hour is actually using the system.

Provide the java code for the following scenario.

Hi Experts,
I have tried with all the combinations for this scenario. As per my understanding i require java code for the following scenario
so that it becomes easy........
I require a Message mapping for this Logic.
In the Source there are 4 fields and, the Target side, the fields should appear like this.
Source Structure- File
Record
|-> Header
Order_No
Date
|-> Item
Mat_No
Quantity
Target Structure-IDoc
IDoc
|-> Header
|-> Segment
Delivery_Order_No
Recv_Date
|-> Item
|-> Segment
Delivery_Order_No
Material_Num
Recv_Quantity.
The Logic is for every Order number an IDOC is generated.And if the Material num matches then the quantity should be added. and important note is that the material numbers are different for every order number. That means if a material number is 2 in the order number A. Then the material number can never be 2 in any of the order numbers.Here is the following with an example for the above scenario.
For example:-
we have
Source Structure- File
Order-no Date Mat_No Quantity
1 01/02/2011 A 10
1 01/02/2011 B 15
1 01/02/2011 A 10
2 01/02/2011 C 10
2 01/02/2011 C 10
3 01/02/2011 D 20
3 01/02/2011 D 10
3 01/02/2011 E 25
Target Structure-IDoc
Delivery_Order_No Recv_Date Material_Num Recv_Quantity
1 01/02/2011 A 20
1 01/02/2011 B 15
2 01/02/2011 C 20
3 01/02/2011 D 30
3 01/02/2011 E 25
So for this example total of 5-Idocs created. That means for this example if Order_No is 1 When the Mat_No is A the quantity gets added. For this Scenario 1 IDoc with four Fields 2 in Header(Delivery_Order_No, Recv_Date) and 2 in Item(Material_Num, Recv_Quantity) is generated by adding the quantity field in the Target Side. Similarly if Order_No is 1 when the Mat_No is B then separate IDoc is generated with four Fields 2 in Header(Delivery_Order_No, Recv_Date) and 2 in Item(Material_Num, Recv_Quantity) in the Target Side. Similarly, if Order_No is 2 when the Mat_No is C, an IDoc is generated with four Fields 2 in Header(Delivery_Order_No, Recv_Date) and 2 in Item(Material_Num, Recv_Quantity) by adding the quantity field in the Target Side. ike wise the process goes on upto 3.Kindly do the needy..
Kindly provide the java code.
Thanq very much in advance..

what i have understood from ur example is that u want to generate an idoc for unique combination of Order-no and Mat_No
if yes then chk the below mapping..
change the context of Order_No, Date, Mat_No and Quantity to Record (right click-> context)
1)
Order-no
----------------------concat[;]---sort----splitbyvalue(valuechanged)-----collapse context---IDoc
Mat_No
2)
Order-no
--------concat[;]---sort----splitbyvalue(value changed)---collapse context---UDF1--splitbyvalue(each value)--Delivery_Order_No
Mat_No
3)
Order-no
-----------concat[;]---sortbykey----------------------- \
Mat_No                       /                            \
Date--------------- /                                       \
----------------------------------------------------------FormatByExample-----collapsecontext---splitbyvalue(each value)----Recv_Date
Order-no                                                 /
-----------concat[;]---sort----splitbyvalue(value changed)
Mat_No
4)
Order-no
--------concat[;]---sort----splitbyvalue(value changed)---collapse context-UDF2--splitbyvalue(each value)--Material_Num
Mat_No
5)
Order-no
-----------concat[;]---sortbykey
Mat_No                       /
Quantity --------------- /
----------------------------------------------------------FormatByExample-----SUM(under statistic)----Recv_Quantity
Order-no
-----------concat[;]---sort----splitbyvalue(value changed)
Mat_No
UDF1:
String [] temp= a.split(";");
return temp[0];

Error while calling the java proxy with the ValueMapping repl scenario

Hi All
I am trying to upload values in the RWB for vaue mapping using the standard ValueMappingReplication interface . But I can see the following message in the Message Display Tool of the RWB .This scenario was working fine sometime back suddenly after some days we started to see this exception .
JPR could not process the message. Reason: No such method valueMappingReplication (for the asynchronous replication scenario) in proxy bean localejbs/sap.com/com.sap.xi.services/ValueMappingApplication
Delivery of the message to the application using connection JPR failed, due to: com.sap.aii.af.ra.ms.api.DeliveryException: No such method valueMappingReplication (for the asynchronous replication scenario) in proxy bean localejbs/sap.com/com.sap.xi.services/ValueMappingApplication: com.sap.aii.proxy.xiruntime.core.XmlInboundException: No such method valueMappingReplication (for the asynchronous replication scenario) in proxy bean localejbs/sap.com/com.sap.xi.services/ValueMappingApplication.
Can anyone please guide me what could be the done to resolve this .
Thanks.

This may happen when the java proxy is not registered. Use the following URL to do so

You've got me thinking, that might be part of the problem with computing today, not enough moving parts. No big tape drives spinning and oscillating. And few if any line printers anymore. Now there's an interesting piece of equipment.

Reaching the java file outside the package?

Hi how can i reach the java(or class) files outside the packge(i mean one top folder)
For example i have a java file in a folder named tech and i want to reach a java file in the folder named support which is under tech folder is something like that possible if it is how?

Then tech should also be in a package.
So it would be..

How to work around the java runtime bug -The indentation is overridden

Hello all,
I generate xml from a servlet and stream to client as the following code. It works fine in my local machine (The xml is indented nicely) but when the war file deployed on a geronimo server 2.0.2. (It uses java 1.5.0_16). The xml streamed out without indentation
               response.setContentType("application/xml");
               response.setHeader("Content-disposition","attachment; filename="+fileName);
               // set up a transformer
               TransformerFactory transfac = TransformerFactory.newInstance();
               Transformer trans = transfac.newTransformer();
               trans.setOutputProperty(OutputKeys.METHOD, "xml");
               trans.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
               trans.setOutputProperty(OutputKeys.STANDALONE, "yes");
               trans.setOutputProperty(OutputKeys.VERSION, "1.0");
               trans.setOutputProperty(OutputKeys.INDENT, "yes");
               trans.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "4");
               // create string from xml tree
               DOMSource source = new DOMSource(doc);
               ServletOutputStream os = response.getOutputStream();
               OutputStreamWriter w = new OutputStreamWriter(os, "UTF-8");
               StreamResult result = new StreamResult();
               result.setWriter(w);
               trans.transform(source, result);This is the bug: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6337981 (The indentation is overridden)
I tried the work around suggested there by using OutputStreamWriter, it doesn't help.
(I cannot change anything on the server. I have to accept whatever in the server)
Please help
Thank you
Edited by: mycoffee on Jun 10, 2011 8:16 AM

You have to set the indent level on the factory, see bug #6296446. This only affects 1.5; 1.6 allows you to set the indent level on the transformer, as you did (and for cross-version compatibility, setting it on both doesn't hurt).
transfac.setAttribute("indent-number", Integer.valueOf(4));
