Read Java System Property from another program

I'm actually talking about the parameters you can set on the Java Control Panel when deploying applets.
I have to check if one parameter is passed (-Dsun.java2d.noddraw=true) from a C++ program I'm writing.
I can check the <%AppData%>\Sun\Java\Deployment\deployment.properties file for the entry sun.java2d.noddraw=true. But this doesn't guarantee anything, if it isn't there maybe is set in the console (which has to store settings somewhere).
Is there a way of checking if DirectDraw is disabled for an already running Applet?
Thanks

It'd be great if the Java Console stored everything in the registry, if it does, do you happen to know where?set the value and then use regedit to search for it.

But the property I have to check only has effect at startup of the VM, so it may have been set at startup and then "deleted from the registry", so i would go there and find nothing, but DirectDraw is disabled anyway.That of course is what I meant by restricting the space. What if there are two different browser types running? What if an update occurs after your C++ app has started?
Given that you are going to run a C++ app on the client anyways why not just make the applet tell you, via a socket, what it is set to?

Why can't change default cipersuits of JSSE by java system property?

I am using jdk1.5.0_17,Now I am trying to change default ciphersuits of JSSE by java system property,so all code can be kept unchanged.In JSSE Reference Guide I know default ciphersuits can be customized by https.cipherSuites system property.I run my program by java -Dhttps.cipherSuites=SSL_RSA_WITH_RC4_128_MD5 myProgram
but it doesn't work.the default ciphersuits of jre are always used.I am not able to change it.
any comments? your help will be appreciated.

Well that only works with HTTPS, i.e. with URLs and HttpsURLConnections. If you're using Sockets directly you have to use the API.

How to call an alv report from another program and return back

     Hello ,
I am calling one abap program (Prgm B) from another program (Prgrm A).
Here, Prgm B is an ALV report. I have fetch some data from Prgem B that gets stored in an internal table.
Now, I am using below code in Prgrm A,
SUBMIT Prgrm B VIA SELECTION-SCREEN
                      WITH SELECTION-TABLE rspar
                      EXPORTING LIST TO MEMORY
                      AND RETURN.
When Prgrm A executed, it lead me to selection screen of Prgrm B and when I click F8, it shows me the report output, In short, it doesnt return back to Prgrm A. It ends up showing me the alv report if Prgrm B even afetr using RETURN statement.
I want to get back to Prgrm A by fetching some data from Prgrm B.
Please let me know, if i am missing something.

CALL TRANSACTION 'ME33K from another program

Hi,
I ma trying to CALL TRANSACTION 'ME33K from another program, but it is not working. The transactions is opening, but it is not opening with the contract number (ls_ekpo-ebeln) i am passing.
ls_ekpo-ebeln does have a valued when CALL TRANSACTION 'ME33K is called.
In debug, I noticed the "value" is blank when step into CALL TRANSACTION 'ME33K .
   WHEN 'EBELN'. "Contract
      l_field = 'EVRTN'.
     IF ls_ekpo-ebeln <> ''.
        GET PARAMETER ID 'VRT' FIELD l_field. "EVRTN.
       SET PARAMETER ID 'VRT' FIELD ls_ekpo-ebeln.
       CALL TRANSACTION 'ME33K AND SKIP FIRST SCREEN.
        SET PARAMETER ID 'VRT' FIELD ls_ekpo-ebeln.
      ENDIF.
Any help or suggestions would be great.
Thanks,

Dear Naing,
I execute the same code
IF ls_ekpo IS INITIAL.
GET PARAMETER ID 'VRT' FIELD LS_EKPO.
SET PARAMETER ID 'VRT' FIELD ls_ekpo.
CALL TRANSACTION 'ME33K' AND SKIP FIRST SCREEN.
SET PARAMETER ID 'VRT' FIELD ls_ekpo.
ENDIF.
And it is working.
Try to do de simple sintax.
A program with one pararmeter to introduce the contract number.
The set parameter for this parameter and the call transaction.
I´m waiting your comments.

Java.system.property

I repost Craig Sandin's question, which was post on Feb 06th. I have the same problem
as him.
I have used java.system.property in my wls 5.1 weblogic.properties file, and it
set a system property I could get at runtime. Is there an equivalent in wls 7.0?
I haven't found anything in the documentation for config.xml. Obviously I can
pass -D options to the jvm, but I was looking for a way from the config file.
hongjie

We don't offer this anymore.. Sorry.
You could write your own very simple
wrapper class to start WLS:
Properties props = new Properties();
props.load(new FileInputStream("weblogic.properties");
System.setProperties(props);
weblogic.Server.main();
Cheers

Checking whether field-symbol from another program is assigned?

Hi all
I'm attempting to access a FS from another program.
As the FS can be assigned, or unassigned within that program, how do I checked for that in my calling program?
e.g. calling program;
FIELD-SYMBOLS: <fs> TYPE STANDARD TABLE.
DATA: lv_var(40) type c.
lv_var = '(ZTGT_PROG)<read_fs>'.
ASSIGN (lv_var) TO <fs>. " statement might dump...

Hi
Go through this doc and use accordingly
Field Symbols
Field symbols are placeholders or symbolic names for other fields. They do not physically reserve space for a field, but point to its contents. A field symbol cam point to any data object. The data object to which a field symbol points is assigned to it after it has been declared in the program.
Whenever you address a field symbol in a program, you are addressing the field that is assigned to the field symbol. After successful assignment, there is no difference in ABAP whether you reference the field symbol or the field itself. You must assign a field to each field symbol before you can address the latter in programs.
Field symbols are similar to dereferenced pointers in C (that is, pointers to which the content operator * is applied). However, the only real equivalent of pointers in ABAP, that is, variables that contain a memory address (reference) and that can be used without the contents operator, are reference variables in ABAP Objects.
All operations programmed with field symbols are applied to the field assigned to it. For example, a MOVE statement between two field symbols moves the contents of the field assigned to the first field symbol to the field assigned to the second field symbol. The field symbols themselves point to the same fields after the MOVE statement as they did before.
You can create field symbols either without or with type specifications. If you do not specify a type, the field symbol inherits all of the technical attributes of the field assigned to it. If you do specify a type, the system checks the compatibility of the field symbol and the field you are assigning to it during the ASSIGN statement.
Field symbols provide greater flexibility when you address data objects:
If you want to process sections of fields, you can specify the offset and length of the field dynamically.
You can assign one field symbol to another, which allows you to address parts of fields.
Assignments to field symbols may extend beyond field boundaries. This allows you to address regular sequences of fields in memory efficiently.
You can also force a field symbol to take different technical attributes from those of the field assigned to it.
The flexibility of field symbols provides elegant solutions to certain problems. On the other hand, it does mean that errors can easily occur. Since fields are not assigned to field symbols until runtime, the effectiveness of syntax and security checks is very limited for operations involving field symbols. This can lead to runtime errors or incorrect data assignments.
While runtime errors indicate an obvious problem, incorrect data assignments are dangerous because they can be very difficult to detect. For this reason, you should only use field symbols if you cannot achieve the same result using other ABAP statements.
For example, you may want to process part of a string where the offset and length depend on the contents of the field. You could use field symbols in this case. However, since the MOVE statement also supports variable offset and length specifications, you should use it instead. The MOVE statement (with your own auxiliary variables if required) is much safer than using field symbols, since it cannot address memory beyond the boundary of a field. However, field symbols may improve performance in some cases.

Syntax Diagram
FIELD-SYMBOLS
Basic form
FIELD-SYMBOLS <fs>.
Extras:
1. ... TYPE type
2. ... TYPE REF TO cif
3. ... TYPE REF TO DATA
4. ... TYPE LINE OF type
5. ... LIKE s
6. ... LIKE LINE OF s
7. ... TYPE tabkind
8. ... STRUCTURE s DEFAULT wa
The syntax check performed in an ABAP Objects context is stricter than in other ABAP areas. See Cannot Use Untyped Field Symbols ad Cannot Use Field Symbols as Components of Classes.
Effect
This statement declares a symbolic field called <fs>. At runtime, you can assign a concrete field to the field symbol using ASSIGN. All operations performed with the field symbol then directly affect the field assigned to it.
You can only use one of the additions.
Example
Output aircraft type from the table SFLIGHT using a field symbol:
FIELD-SYMBOLS <PT> TYPE ANY.
DATA SFLIGHT_WA TYPE SFLIGHT.
ASSIGN SFLIGHT_WA-PLANETYPE TO <PT>.
WRITE <PT>.
Addition 1
... TYPE type
Addition 2
... TYPE REF TO cif
Addition 3
... TYPE REF TO DATA
Addition 4
... TYPE LINE OF type
Addition 5
... LIKE s
Addition 6
... LIKE LINE OF s
Addition 7
... TYPE tabkind
Effect
You can define the type of the field symbol using additions 2 to 7 (just as you can for FORM parameters (compare Defining the Type of Subroutine Parameters). When you use the ASSIGN statement, the system carries out the same type checks as for USING parameters of FORMs.
This addition is not allowed in an ABAP Objects context. See Cannot Use Obsolete Casting for FIELD SYMBOLS.
In some cases, the syntax rules that apply to Unicode programs are different than those for non-Unicode programs. See Defining Types Using STRUCTURE.
Effect
Assigns any (internal) field string or structure to the field symbol from the ABAP Dictionary (s). All fields of the structure can be addressed by name: <fs>-fieldname. The structured field symbol points initially to the work area wa specified after DEFAULT.
The work area wa must be at least as long as the structure s. If s contains fields of the type I or F, wa should have the structure s or at least begin in that way, since otherwise alignment problems may occur.
Example
Address components of the flight bookings table SBOOK using a field symbol:
DATA SBOOK_WA LIKE SBOOK.
FIELD-SYMBOLS <SB> STRUCTURE SBOOK
DEFAULT SBOOK_WA.
WRITE: <SB>-BOOKID, <SB>-FLDATE.

How to create a variant to a report from another program at run time

Hi experts,
when i am using FM : /OSP/REPORT_CREATE_VARIANT to create a report variant from a program then i am getting an error 'For object /OSP/ERPNR , number range interval 01 does not exist ', how should i avoid it or can any one help me out to create a report variant from another program at run time with the results of the program.so that i can execute the report from here with this variant

If i understand you,
- You can use a FM like [RS_CREATE_VARIANT|https://www.sdn.sap.com/irj/sdn/advancedsearch?cat=sdn_all&query=rs_create_variant+&adv=false&sortby=cm_rnd_rankvalue] to create a variant and then use it in the [SUBMIT|http://help.sap.com/erp2005_ehp_03/helpdata/EN/fa/096d67543b11d1898e0000e8322d00/frameset.htm] statement USING SELECTION-SET.
- But you may also use SUBMIT with WITH parameters which doesnt require variant creation and with much less programming efforts.
- You can mix the two solutions also.
So what is you actual requirement, also look at some documentation like [ Scheduling a Job: Full-Control Method|http://help.sap.com/erp2005_ehp_03/helpdata/EN/fa/096ce5543b11d1898e0000e8322d00/frameset.htm]

Setting up java.system.property in WL 6.0

Hi all,
I just installed Web Logic 6.0. I would like to know if anyone knows how
to set java.system.property in Web Logic 6.0
In old Web Logic 5.1, I added this line in weblogic.properties file. Now
since we don't have weblogic.properties file anymore, I am assuming this
should go in config.xml. Documentation says I should use Admin Console
to modify config.xml and to convert old weblogic.properties file, but I
found Admin Console confusing.
My Web Logic 6.0 is installed on d:\bea\. I clicked on Convert
Weblogic.properties and I see directories on my system. I click on icon
to get the directory that has weblogic.properties file. Then I get page
that ask me to pick Clusters and Server and I have no idea what
directory I need to click on
If someone knows what to do next or how to edit Config.xml so that I can
add my java.system.property, please e-mail me
Thanks in advance
Qaiser

Did you see the directions on page 3-11 of the WLS 6.0 Administration Guide? I
followed these steps, and was able to create a new domain. I found them to be
clear.

How to open-up a pdf file to a particular page via java? (file and page number from another program)

I have created an Access 2003 Form. Data is entered. The data can be viewed once entered in the same form format, with one addition. The addition is a link to another program where we store files. The files stored are pdf documents. Each document is a scanned file (500+ pages). The link can open-up the pdf file. I want the link to open-up the pdf file to a particular page. I will supply the page number from the database.
I am aware of Adobe Acrobat 7.0 PDF Open Parameters using a URL that specifies the file to be opened plus actions to be performed once the file is openend (i.e. http://example.org/doc.pdf#page=3). However, the 3rd party program transfers a file from a server to the client via java. The file does not go via a web browser. The java code transfer the file directly from the file server to the the client.
Any idea how to accomplish the task of viewing a particular page with the process flow described?
I am using Adobe Acrobat 7.0 Professional.

So you are reading this file in a standalone version of Acrobat? If so then use the PDF Open Parameters /a option via the command line.
Sabian
Example:
C:\Program Files\Adobe\Acrobat 7.0\Acrobat>Acrobat.exe /A "zoom=1000=OpenActions" "C:\Program Files\Adobe\Acrobat 7.0\Acrobat\SimpleSubmit.pdf"
Where:
Path to Acrobat: C:\Program Files\Adobe\Acrobat 7.0\Acrobat>Acrobat.exe
Note: The example starts in the Acrobat application directory
Switch: /A
Parameter Syntax: "zoom=1000=OpenActions"
Path to file: "C:\Program Files\Adobe\Acrobat 7.0\Acrobat\SimpleSubmit.pdf"
Note: The quotes are very important for the syntax to work appropriately.
