Types of methods

What are class methods and instance methods? What are the differences between the two?

Question on using table types in methods

Hi
I have a simple question involving passing table types in method
I want to pass an internal table by reference - to a method and within the method populate the internal table (t1) using a select * into the internal table and then sort t1 by f1 and f2. t1 is an internal table based on a ABAP dictionary table ( at1 )
Question is : If I use a generic type TABLE declaration , it does not allow sort operation specifically by fields. If I use type at1 as in
the METHODS M1 exporting t1 type at1statement, syntax error is - t1 is not an internal table.
How do I achieve the above using the method implementation ?
Sample code that I try
CLASS C1 DEFINITION
PUBLIC SECTION
METHODS M1 exporting t1 type table
ENDMETHOD
ENDCLASS
CLASS C1 IMPLEMENTATION
METHOD M1
select * from at1 into t1.
sort t1 field f1 f2
ENDCLASS

You should define a TABLE TYPE based upon the data dictionary type (at1) either in the data dictionary using SE11 or in the TYPES section of the class.
Then define the parameter of this new type.

Trying to uderstand different types of methods.

Well, basically, I'm trying to uderstand the different types of methods there are.
I uderstand private static, public static, private void and public void. Public means the method can be called from another class, private means method can only be called from within its own class. Static - some value is going to be returned, Void - no values are returned.
These are the ones I don't understand for sure;
static {
try { ... }
catch(...) { ... }
} This method tries to do something and catches exception. But, it isn't public or private and it doesn't have a name, how does it fire?
A void someName() method with no public or private prefix. Who can fire this method?
final void someName(), static class someName(), and protected void someName() are other methods I don't understand.
All help appreciated.

Static - some
value is going to be returned, No. Static means the method is associated with the class as a whole, not with any particular instance of the class. It has nothing to do with what, if anything, it returns.
These are the ones I don't understand for sure;
static {
try { ... }
catch(...) { ... }
This method tries to do something and
catches exception. But, it isn't public or private
and it doesn't have a name, how does it fire?It's not a method. It's a static initializer. It runs when the class is loaded.
A void someName() method with no public or
private prefix. Who can fire this method?Without public, protected, or private, it's "default access" or "package access." It's only accessible within that class or to classes in the same package.
>
final void someName()[/i
], static class
someName(), and protected void someName()
are other methods I don't understand.
You should go through a tutorial or introductory text.

Cannot send complex type as method parameter

Cannot send complex type as method parameter
Hi!
I'm using a kSOAP 1.2 client and i'm having trouble executing a method that takes an object
of complex type as parameter:
method:
public void addSquareDetail(SquareDetail sd){/stuff}
-SquareDetail is a java bean class that implements KvmSerializable
- a mapping was added to classmap
-legacy namespace is not an issue (i AM able to execute the following methods successfully
over kSOAP):
-getting one SquareDetail object
-getting a vector of squareDetail objects
Here's how i'm trying to call the 'send' method:
ClassMap classMap = new ClassMap();
classMap.addMapping("urn:SquareWebService/types", "SquareDetail", (new
SquareDetail()).getClass());
System.out.println("add one SquareDetail");
request = new SoapObject(serviceURN, "addSquareDetail");
sd = new SquareDetail();
request.addProperty("SquareDetail_1", sd);
tx = new HttpTransport(this.endPointURL, "addSquareDetail");
tx.debug = true;
tx.setClassMap(classMap);
tx.call(request); //exception here
(above:)
private String endPointURL = "http://localhost:8080/SquareWebService/SquareWebService";
protected static final String serviceURN = "urn:SquareWebService/wsdl";

So, apparently, the request message is not understood by the server. what exactly is it
missing, and how can i add/correct that? (my guess in SquareDetail_1 xmlns="" should be
"urn:SquareWebService/types", although it's just a guess AND i don't know how to make kSOAP
get it in there)
I'm not sure what kind of SOAP parser my app server utilizes, but i'm guessing it's an
apache product (how can i tell?). I also have a WSDL file available, should anyone be
willing to look at it, please let me know
thanks
-nikita

Don't know if it will help but Can you check if the serializable object has a public empty no args constructor with an empty call to super()
Also make sure that a type mapping registry is added with a reference to the serializable object in it.
Please paste The WSDL as well

Object type component method name is not supported by object type BOR

Hi All,
Just want to get your help on the above error message in my workflow step.
The method is successfully created in the BO, no errors, status is released/implemented. This error only occurs when the workflow is triggered by a RFC call using SWE_EVENT_CREATE FM. But when using t.code SWUS or SWUE the workflow will run as expected, no error. And when the erroneous workitem is restarted using SWPR, it will run or continue successfully.
Another thing, this is newly created task and method inserted in the workflow. If i delete this task, the workflow will run successfully when triggered by the same RFC.
Hope you guys have already experienced this kind of error.
Thanks in advance.
Matt

Hi Matt,
I am trying to analyse the problem.
When you trigger the workflow using function module it gives error. But when you trigger using SWUE or restart workflow then you do not get error.
In both the cases ( SWUE or restart workflow ) event is getting called using system. But when you trigger it prgramatically it throws error. I hope you are triggering it correctly.
But as you are saying, when you delete the task and method it works fine. So that means it should not be triggering issue.
Just do consistency check for the business object. Check if there is any issue in method.

Instantiating anonymous Type as method argument...

hi,
trying to do this, i guess i have stumbled upon a noob's syntax error. any help please?
    private <T extends Dimension> void fillArray(T dim, ArrayList<T> arrayList) {
        for (int i=0; i<dim.getDim();i++) {
            arrayList.add(new <T>(i+1));
    }the error is spotted in the third line and the compiler says: <identifier> expected
thnx!

you cannot do this because of the way java has defined generics. you either need some factory instance which knows how to create new T instances or a class of type T from which you can reflectively call the relevant constructor.

Incompatible type for method

this is for school so you don't have to answer if you choose not to.
i have to have method signature that reads
public void BFEncrypt(String source, String target, byte code)throws IOException, FileNotFoundException{
but when i call the method
bfp.BFEncrypt("C:/WINDOWS/Desktop/ASSIGN3/test.txt","result.txt",12);
i'm told i have to convert an int to byte. it is defaulting the 12 at the end of the call to an int. i got the class, which is to read a file, encode it using the simple code passed in, and then re-write to work fine when making the signature int code. I was told that it had to be byte though and i can't get it to work.
thanks in advance

Well, then overload the method..
public void BFEncrypt(String source, String target, int code)throws IOException, FileNotFoundException {
//whatever goes here
public void BFEncrypt(String source, String target, byte code)throws IOException, FileNotFoundException {
BFEncrypt(source, target, (int) code);
}You could even test for values >127 <-128 and throw an exception. And you can use the same technique for short or long. (I did not try to compile this so no guarantees.)

Which types of methods cannot be traced?

Hi, all,
I met a very strange question. Assume in one class, there are 3 methods called methodA(), methodB(), and methodC(). methodA() will call methodB and methodC. I add methodA, methodB and methodC into method profiling. I can trace the running time on methodA and methodB, but cannot trace the running time of methodC. The running time of methodC always display "?". And the hint message is "Some of the methods might not be loaded by Jrockit". But in fact, if I can add it, it must be already loaded successfully.

OS: Win2003 English
WLS: weblogical 8.1
JROCKIT: jrockit81sp3_142_04
Today I found in the API, if we use Array as parameter, then this method cannot be traced by JRockit Management Console.
Here is an example:
public void testSync(String server) {..}
public void testSync(String[] servers {â€¦}
Above two methods, testSync(String[] servers) cannot be traced by JRockit Management Console.

Types of method calls in OO ABAP

Hai all,
Is there call by value and call by reference is there in OO ABAP or not.

Method parameters can be passed by either reference or value. In SE24 this is specified via a checkbox against the parameter.
The exception is RETURNING' parameters - these can only be passed by value.

What type of method is this

System.out.println("Enter a sentence:");
z = keyboard.hasNext();
while (z) {
x = keyboard.next();
System.out.println(x);

well what is it missing, im trying to create a program that will read a sentence and print each individual line of the sentence

Deep DDIC-Structure - Method to get the Comp.Type of a sub-structure

Dear colleagues,
thought the subsequent piece of coding might be helpful for the following problem:
In DDIC you have created a deep/nested Structure e.g. a complete Business Document representation like
s_doc_header type struct_doc_header
     (incl.) item type tab_item
        (incl) party type tab_party etc.
Now for some purpose you need to access somewhere a sub-part of this structure, e.g. the party-part. You only know (dynamically) the component name "party", but need for dynamic access also the Component Type ("tab_party") (in order to make use of a "CREATE DATA lr_reftodata TYPE (determined_comp_type)." )
The following piece of coding should help to query any start component type (here "struct_doc_header") for its embedded components.
Its a recursive use of features provided by the very nice class(set) of cl_abap_structdescr.
I implemented it as a static method.
When doing so, you need to ensure, that the TYPE-GROUP "ABAP" is linked to the class (class properties --> forward declarations),
Let me know if you find it useful.
And apologies in advance, if the same problem was already posted in the forum. I did only a rough search before due to a lag of ideas for appropriate search-strings ...
Best regards,
Rudy

Type parameter in 'add' method of 'ArrayList'

My little application utilizes an object of type 'ArrayList', especially because this class enables the size increment of the list by successive actions after its creation. http://java.sun.com/javase/6/docs/api/ shows that I can use the method '*add(E e)*' for this purpose.
The IDE I use is 'NetBeans IDE 6.5'.
My object of type 'ArrayList' is multi-dimensional and to build it up, I make use of a re-entering method. At the end of this last, one can thus see :
chaîneCible.add(descendant);
return (chaîneCible);In 'chaîneCible.add(...',
1) if I don't write the type E of the object e to append ('descendant')
- the pre-compiler doesn't grumble : It does not underline the statement in red
although the type of method parameter, own to 'descendant', is missing - e.g. 'String'.
- the debugger grumbles :
Note: C:\Documents and Settings\Me\My documents\ApplicPrograms\Application7\src\package\NoeudàCaseàCocher.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.2) if I add the type E of the object e to append - e.g. 'BigDecimal' - then
- the pre-compiler grumbles :
- It underlines the statement in red.
- "Missing ;" + "Cannot find symbol" + "Symbol : variable String" + "location : ..."
Confusion : It takes the type for an argument !
- although the API stipulates that it is mandatory to specify the type of the parameter in front of it.
3) I don't know when anymore, the compiler returned
Class 'ArrayList' - method 'add'
automatic casting of a 'String' into an 'Object' is refuted at compilationWhy cannot I specify the type E of the argument e, as the API requires ?
Thanks in advance.

Dear DrClap,
Here is an intermediate source code (121 lines) of my original code file (1145 lines) which is working well, except this arrayList.*add(E e)* issue.
You see here the declaration of the ArrayList, the code where I add entries to the ArrayList, the code where I try to "add the type E ...
By writing *add(E e)*, I am simply using the syntax mentioned in http://java.sun.com/javase/6/docs/api/
I guarantee that the code that I filtered out is not relevant to my arrayList.*add(E e)* issue.
It is going on a parser that inserts String data from an auxiliairy file at the time of parsing the principal source file (chaîneSource), to generate a target file (chaîneCible).

How to declare a param. of type RANGE OF in a method (or function module)?

Hello,
I've got a following problem.
I want to pass a value of type RANGE OF to a method declared in
an interface (the interface is built using Class Builder). I don't know
how to do that and I did not manage to find a solution using both
SAP help and google.
Did anybody have the same problem before?
Best regards
Pawel

Ok, I find a workaround. Maybe it will be useful for somebody in the future.
Declare the parameter type as ANY TABLE and then cast it to the expected type
in the body of the method.
So for example.
Parameter          Type        Typing Method        Associated Type
I_RNG_DATUM Importing Type                         ANY TABLE
In the body of the method.
TYPES:
    erdat_range TYPE RANGE OF erdat.
FIELD-SYMBOLS:
    <l_fs_rng_erdat> TYPE erdat_range.
DATA:
    l_ref_to_range TYPE REF TO data.
GET REFERENCE OF i_rng_datum INTO l_ref_to_range.
ASSIGN l_ref_to_range->* TO <l_fs_rng_erdat> CASTING.
However, if somebody know how to pass type RANGE OF
explicitely, the right answer is still welcome.
Best regards
Pawel

if think the problem is in /etc/dbus-1/system.conf
<deny send_type="method_call"/>
I'm tempted to change this to allow, but I won't as long as I don't understand why this deny-rule is implemented.

That deny rule is the default. Things in /etc/dbus-1/system.d override it. There's a ConsoleKit.conf file in there that describes what interaction ConsoleKit actually allows.
That said, ConsoleKit.conf also denies this access:
<deny send_destination="org.freedesktop.ConsoleKit"
send_interface="org.freedesktop.DBus.Properties" />
I don't know why this is denied - most likely it's to prevent private data from being stolen from console-kit-daemon in this way. I don't see any such private data stored in properties on ConsoleKit, though:

Note those properties at the end of that list, which are the same things you can learn by running ck-list-session.
If you want to change the deny to allow, you may as well do it in the ConsoleKit.conf line, so it's specific to this usage, rather than allowing any method call in the world called through dbus.
FWIW, I can reproduce this same error, trying to do it "by hand", though I don't use GNOME, as you do:
$ dbus-send --print-reply --system --type=method_call --dest=org.freedesktop.ConsoleKit /org/freedesktop/ConsoleKit/Session1 org.freedesktop.DBus.Properties.GetAll string:org.freedesktop.ConsoleKit.Session

Help: Connecting Tomcat to CA-IDMS Using JDBC Type 4 Drivers (JNDI)

Hi there,
I have a rather interesting / complex problem......creating a connection to CA-IDMS from Tomcat using JDBC type 4 drivers (CA provide the type 4 driver).
We have a zSeries 9 IBM mainframe running CA-IDMS r16.1, and I need to connect to the IDMS from Tomcat (running on Linux) using the JDBC Type 4 drivers provided by CA.
At this stage I am struggling with the actual setup and configuration of Tomcats server.xml and web.xml files. These are the files where the JDBC configuration is set (I think). I have to setup the CA-IDMS part of the configuration, but that is a different problem. Basically there is a TCP/IP listener on the IDMS, waiting for incoming connections from the JDBC type 4 driver.
I set up a Tomcat to MySQL connection using MySQL Connector / J, which is a similar kind of process to what I am trying to achieve with IDMS. MySQL connector / J came with a jar file which is placed in Tomcats lib folder, and then the JDBC setup for the web application is created in Tomcat's server.xml and web.xml files. You can then connect to the MySQL database using JSP and the configured JDBC driver / connection. The CA-IDMS Server comes with an idmsjdbc.jar file, which I think is the JDBC typr 4 driver. I think it needs to be placed in the Tomcat /lib folder, but I dont know how to set up the configuration.
There is a JDBC DriverManager which allows JDBC drivers to connect to CA-IDMS. The DriverManager recognises the following syntax:
jdbc:idms://hostname:port/database
This allows the JDBC driver running within Tomcat to connect to the IDMS which is running on the IDM mainframe. CA IDMS r16 supports direct connections from the Type 4 JDBC driver to the Central Version on IDMS. "hostname" is the DNS name or IP address of the machine where the CV is running, and "port" is the IP port that was specified for the listener PTERM (setup on the IDMS side).
There is a caidms.properties file for the JDBC driver, which is used to specify user ID, password, and optional accounting information. It can also be used to specify physical connection information, allowing an application to connect to a CA-IDMS database without requiring the definition of an ODBC style data source. However, I dont know where to place this file within the Tomcat setup.
There is also an IdmsDataSource class. I dont know where to configure this or how to set it up; the CA-IDMS Server manual states the following:
This class implements the JDBC DataSource interface. It is used with an application server (Tomcat) providing Java Naming and Directory Interface (JNDI) naming service to establish a connection to a CA IDMS database. IdmsDataSource properties conform to the Java Beans naming conventions and are implicitly defined by public setter and getter methods. For example, the description property, which is required for all DataSource implementations, is set using the setDescription(String) method. The application server may use the java.lang.reflection methods to discover DataSource properties and provide an interface to set them, or may simply require that they are defined in some configuration file. IdmsDataSource properties are used to specify the connection parameters. These properties are the equivalent of the DriverPropertyInfo attributes described in the previous section and can be used to completely define the parameters needed to connect to a database. Like a URL, an IdmsDataSource object can also reference an ODBC style data source name, where the connection parameters are defined in the configuration file on Linux.
Is there anyone that can try to point me in the right direction to setting up the JDBC connection? I am totally new to Java and so the instructions are not making much sense at the moment. Any help, hints, tips..anything will be greatly appreciated as I have just hit a brick wall here. I can't find much to do with setting up the CA-IDMS Server JDBC type 4 driver online either....if anyone can point me to some resources that would also be extremely useful.
Kind regards
Jp

You say you've managed to get the JDBC driver working
in an application but not in a JSP. You also say that
the error you get is
"com.microsoft.jdbc.sqlserver.SQLServerDriver".
I'd be willing to bet that the exception that you have
got is a ClassNotFoundException. I.E. your application
server hasn't found the JDBC driver classes. The
application server probably doesn't use your current
CLASSPATH to look for classes. It will be setup within
the application server in some way and you'll need to
check your app server documentation to see how it is
done.
Try replacing
e.printStackTrace();with
e.printStackTrace(out);to get a full stack trace of your error.
ColTried it. Got this error when I tried to run the JSP.
Incompatible type for method. Can't convert javax.servlet.jsp.JspWriter to java.io.PrintWriter.
e.printStackTrace(out);
I'm currently using Apache Tomcat 4.0.3 as my JSP/Servlet Container.
I'm also using Type 4 MS SQL Server 2000 JDBC driver version 2.0 on my NT4.0 Server.
Do I need to set my JDBC driver in my container? if so, how do I do that?
