Call transaction from java iView (link)

Hi,
I would like to call SAP R/3 transaction from a java iView. I know how to do it using the UrlGenerator service. Is there any other way of doing that ? (better way)
Thanks, Nir.

You can Use EPCM.doNavigate() to call R3 Transaction or something like this:
<hbj:link id="r3"
          text="R3 Transaction">
<% r3.setOnClientClick("OpenWindow('/irj/servlet/prt/portal/prtroot/com.sap.portal.appintegrator.sap.Transaction?System=SAP_R3&TCode=SE80&GuiType=WinGui');return false;"); %>
     </hbj:link>
Regards,
P.

Run SAP transaction from Java?

I'm looking for answers for two questions:
1) Can I run an SAP transaction from Java & capture the result either in a file or table.. or any such structure?
2) Can I run an ABAP report directly from Java? and then capture the result as well? I realise that I can use the JCO to run any RFC enabled function module..? But what about a report itself.? Can I run the report behind an SAP transaction directly from Java?
I need this information urgently, and would appreciate any help on this.

Hi Deepika,
I think the requirement you have asked is quite complex and there is no solution as far as i have know.
You can use BAPI to run SAP Transactions for example BAPI_MATERIAL_DISPLAY will take you to MM03 transaction when you pass a valid material number to it.
When i searched for the same i ended up with no solution,
but got a good link which gave some idea
http://expertanswercenter.techtarget.com/eac/knowledgebaseCategory/0,295197,sid63_tax296869_idx25_off25,00.html
Go through that link that might be helpful.

Call report from java with deployment of java web start

I need call report from java,the call function is:execURL ( String pURL )
pURL is a url link to call report from report services .
such as :http://10.20.1.43:8888/reports/rwservlet?destype=cache&desformat=PDF&report=test.rdf&user=scott/tiger@cims
public static void execURL ( String pURL )
String tempstr = new String();
int posIdx = 0;
if ( (System.getProperty("os.name").equals("Windows NT"))||
(System.getProperty("os.name").equals("Windows 2000")) )
posIdx = pURL.indexOf("&");
while ( posIdx > 0 )
tempstr = pURL.substring(0,posIdx)+"^"+pURL.substring(posIdx);
pURL = tempstr;
posIdx = pURL.indexOf("&",posIdx+2);
try
Runtime.getRuntime().exec("cmd /c start "+pURL);
catch (Exception e1) {System.out.println(e1.getMessage()); }
else
try
Runtime.getRuntime().exec("start "+pURL);
catch (Exception e2)
System.out.println(e2.getMessage());
It's run with no problem with deployment of simple jar.
But when i call report with deployment of java web start,it can not.
I think it's java secuity problem,so i add
Permission java.io.FilePermission "c://winnt//system32//cmd.exe", "execute";
in java.policy file in client(windows 20000).However ,it can not too.
Who can help me,Thanks in Advance!

David,
In your code, 'cmd' is invoked as Runtime.getRuntime().exec("cmd /c start "+pURL);
but in your policy file you specify
Permission java.io.FilePermission "c://winnt//system32//cmd.exe", "execute";
Before creating a new process, the security manager checks for FilePermission(cmd,"execute")
if cmd is an absolute path, otherwise it calls checkPermission with
FilePermission("<<ALL FILES>>","execute"). Try specifying
FilePermission("<<ALL FILES>>","execute") in your policy file.
But, I believe using exec, may not be the right solution as it may not work on
other platforms. Also you will have to expect the client m/c to relax security
permission.
Did you consider using java.net.HttpUrlConnection class instead to access the report
service URL?

Reading selection parameters of transaction from Java

Hi everyone,
I 'm trying to find a way to read the selection parameters of a transaction from Java code. For example, the transaction MM03 (Display Material) expects a parameter called RMMG1-MATNR. I would like to be able to get the parameter's name in Java code via some RFC using JCO.
Regards,
Yoav.

When the write end of the FIFO pipe is closedNamed pipes can be opened through several file desciptors. When all open file desriptors referring to a pipe are closed, only then is EOF indicated at the reading side. Named pipes "dwell" in the file system, and can be accessed as files through their names in the file system.

"ReferenceError: "myIpAddr" is not defined, when call JavaScript from java

Hi developers,
My java application was trying to issue a http request via proxy auto-config. So, I did below jobs
1. Read URL of *.pac from registry
2. Call FindProxyForURL from java, the code is like below
               ScriptEngineManager factory = new ScriptEngineManager();
               ScriptEngine engine = factory.getEngineByName("JavaScript");
               engine.eval(autoProxyScript);
               Invocable inv = (Invocable) engine;
               Object obj = inv.invokeFunction("FindProxyForURL",
                         "http://java.sun.com/",
                         "java.sun.com");
However, I got "ReferenceError: "myIpAddress" is not defined
I can not change the script on server to add a function like "myIpAddress", I am wordering why IE or mozilla can call it successfully and get proxy server, while Java failed to do that.
I got a ugly solution by calling "pacparser" by jni. But I really hope I can get a better solution.

A .pac file is a JavaScript, but it requires some functions to be defined in the executing context to work (i.e. you must define those).
From the example on the Wikipedia page there's at least "shExpMatch" and "isInNet". "myIpAddress" seems to be another such candidate.

Calling Transaction from other system using RFC

Hi ,
I have one button on screen(say Screen-A), in ECC. when its pressed the transaction '/SAPAPO/BOPIN' gets called from APO.
For calling transaction from APO I am using FM - 'ABAP4_CALL_TRANSACTION'.
I want the initial screen of that transaction to retain some values which I fill on the Screen-A(the screen which has that button).
When I call the transaction from ECC itself (ex. C006), the initial screen of C006 retains the value on Screen-A.
I want the same to happen in case of calling transaction from APO.
How to achieve this? Would it need the changes in IMG (SPRO)?
Please note that, Screen-A is initial screen of transaction 'md05' and I want to retain vaules of Material, MRP Area, Plant.
Thanks,
Sujeet

Builld a RFC enabled FM () that wrap the call of Smartforms (*) in the other system.
Regards,
Raymond

Calling BDC from Java using JCO

Hello Everyone,
Is it possible to call a BDC from Java program using JCO ?

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 Matlab from Java

Hi everybody,
I need to call Matlab from Java, run some programs in matlab and get the standard output.
I know I can start matlab with:
Process proc = Runtime.getRuntime().exec("matlab");
But then how do i run a program in matlab? (For example, if I have "myprogram.m", I would run it in matlab by typing "myprogram")
If I start a new process [Process proc2 = Runtime......exec("myprogram")], it does not start in matlab.
Any ideas?
thanx in advance.

Sounds like myprogram is just a parameter of a call to matlab.
Try some variations on
exec("matlab myprogram");
There is also - I believe - an exzec call that takes an array of parameters.

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.

Calling ant from java

               // 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");

As you can see, the delete operation goes well, but create fails. The NLS_LANG message seems to be shown no matter what the real error was though.
The funny thing is, that I have tried to take the EXACT command with the EXACT parameters my Java application calls, and call it manually, and then it works just fine. Any ideas on how to get this to work? Any ideas what these ORA-XXXXX errors is?
Thank you

Last night when I was somewhere between this world and dream world I scanned through my code in my mind and found the error, and it is my bad... I called the searchadminctl with my thesaurus file as argument, just before I closed my OutputStream to the file, which we all know is quite a bad idea.
So the answer is: it is absolutly no problem to call searchadminctl from Java :)

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.
