Getting value type at runtime
Hello everyone,
I am using Scanner to get tokens from a buffer. I need to know the type (class) of the value returned. Instead of using "if" statement and hasNext?() for each possible type, is there a method that just return the type. Something like:
Class c = get(String s);So, if s is "Address", c would be set to String.class. If s is "true", c would be set to Boolean.class... etc
Thank you
Yeh, I just saw your other post:
http://forum.java.sun.com/thread.jspa?threadID=783200
The two topics are different but related. The topic, you refer to, are taking about getting a value. In that topic I need a method like:
Object o = String.toObject (String s, Class c);However, the topic "Getting value type at runtime" are taking about getting a type. In this topic I need a method like:
Class c = string.getClass();to return the type this string represents.

Getting value type 20 (plan) from 0CO_OM_OPA* extractor
Hi All,
I have 0CO_OM_OPA6 extractor which is for actuals so it extracts value type 10 to bw cube.
Now as per requirements i need to get value type (0VTYPE) 20 into the cube.
I know there is extractor 0CO_OM_OPA_3 extractor which is designed for plan. Which are the tables behind this extractor ? can some one give me the names of the tables ?
is there anyother way i can get value type for plan ?
Thanks,
KSPlease see note note 573962.
This note returns background information for the totals record and line item DataSources for costs in the area of overhead controlling.
These are DataSources for objects with an account assignment:
Cost center,
Process costs,
Requests,
WBS element,
Network,
Network activity and
Network activity element.
The following questions are answered in this note:
Why are there two different DataSources that extract costs for an object with an account assignment?
For which value types do the DataSources return data?
Which DataSources are delta-compatible?
When do the line item DataSources sometimes return values for the costs other than the totals records DataSources?
How do I avoid duplicate values for costs in the InfoCube?
Which selections should I use with the extraction?

Why are there two different DataSources that extract costs for an object with an account assignment?
For which value types do the DataSources return data?
Which DataSources are delta-compatible?
Answer
Totals record DataSources
There is one totals record DataSource for each of the objects with an account assignment.
These are specifically the following DataSources: 0CO_OM_CCA_1, 0CO_OM_ABC_1, 0CO_OM_OPA_1, 0CO_OM_WBS_1, CO_OM_NTW_1, 0CO_OM_NWA_1, 0CO_OM_NAE_1.
The DataSources extract data for the following BW value types, InfoObject
0VTYPE:
10 Actual,
40 Commitment,
20 Cost element planning values
at totals record level from the COSS and COSP database tables.
Furthermore, target costs are still calculated for cost centers from the cost element planning values if the BW value type
30 Target
is selected explicitly.
The totals record DataSources do not support a delta extraction.
Line item DataSources
There is also one line item DataSource for each object with an account assignment.
These are specifically the following DataSources: 0CO_OM_CCA_9, 0CO_OM_ABC_7, 0CO_OM_OPA_6, 0CO_OM_WBS_6, CO_OM_NTW_2, 0CO_OM_NWA_2, 0CO_OM_NAE_2.
These DataSources only return data for the BW value type
10 Actual.
These are actual line items that are read via the COVP view from the COBK and COEP tables.
The line item DataSources support the delta extraction of data.
When do the line item DataSources sometimes return values for the costs other than the totals records DataSources?
Answer
The actual line item DataSources do not deliver any data from R/3 for historical periods if the line item information for these periods were already archived in R/3. We recommend that you then load the actual data for the historical periods into BW through the totals record DataSources.
5. How do I avoid duplicate values for costs in the InfoCube?
6. Which selections should I use with the extraction?
Answer
During the extraction, make sure that actual data in a certain period is either read through the totals record DataSource or the line item DataSource.
You can guarantee this by making a corresponding selection for the selection criterion periods for the line items and the totals record DataSources and by restricting the value types for the totals record DataSource.
If the values of a period are read simultaneously via the totals record and the line item DataSource and these are updated in the InfoCube, this causes duplicate values.
For old periods, the actual data is usually read at totals record level,
since the line items are already reorganized or
because the line items information are no longer required for historical data and, thus, the dataset transferred during the delta initialization of the line items DataSource can reduce.
Typical example for the selections:
0CO_OM_CCA_1
Period : 1995 001 to 2001 016
Value types: Plan, commitment, target, actual
0CO_OM_CCA_1
Period : 2002 001 to 2050 016
Value types: Plan, commitment, target
0CO_OM_CCA_9 Delta procedure for actual values
Period : 2002 001 to 2050 016.

Getting generic type at runtime
Example:
public class GenericTest {
private List<String> list = new List<String>();
How can I get the type String at runtime?
Class c = GenericTest.class;
Field[] fiels = c.getFields();
for (Field f: fields) {
Class fc = f.getDeclaringClass();
// What are the next steps to to get String.class from fc?
}Generic types (ie. the ones inside the < >) get Erased at compile-time. All this type information is therefore not available at run-time
Google "Java Generics Erasure" to get some more info. (There's a Generics forum by the way!) -
Get the Type of a generic field at runtime, How to?
Hello,
As the topic already says, i need to get the Type of a particular field of a class. This field is declared private and generic. In C# there is a method
Type Object.getTypeIs there any specific way to do this in Java 1.5?
Please excuse my poor english.
Thanks in advance.

Type erasure refers to the fact that at runtime, there are not actually multiple class binaries depending on the generic arguments to a class. Therefore, an ArrayList<T> is actually just an ArrayList with no generics.
Frankly, I don't understand why you insist that the information on generic fields that the OP was asking about is lost at runtime.I wasn't trying to insist that. At the time, I was replying more to Saish and trying to reaffirm that most information about generics is lost at run-time. I mistakenly ignored how you qualified it with "field."
What you write about instances of generic classes losing their type information is of course correct, albeit not to the point of the original question.Nope, you're right. I was just trying to reconcile the fact that many people get confused that there's any information available at run-time, and so start down the path of thinking that type erasure doesn't exist. But it very much does.
The original question was about how to obtain the type of a generic field.And I did show in my example that even that is fairly limited, given that if the type is provided by the parameter of the class, it doesn't give you anything useful (I'm not trying to say you said it would!).
The compiler preservers this information in the class file, so it can be obtained at runtime. Frameworks like JPA put this to use extensively, proving that it is of real value.Definitely. However I don't see this having as much to do with generics as basic reflection functionality. If you can get the type of a field at run-time, you should be able to get the parameters as well! That should in no way belittle its value, though. But I would have guessed (knowing little about) that JPA wouldn't put that to use so much as the type parameters of an accessor return type or mutator argument type. Especially since I thought we'd shown that you would need your fields to be non-private for JPA to be able to gain information about their type.
Edit: getDeclaredField works fine with private members, and returns the expected "java.lang.String" from jschell's example above

I am trying to define table type on runtime. Please explain - it is not clear from the code what you are attempting.
Also note that PL/SQL is strong typed language. This mean that you cannot define a variable using a weak type and at runtime change that into a formal data type.
In Oracle, the abstract AnyData data type can be used for unknown data types - and methods exist that allows different data types to be stored and retrieved as AnyData types. Of course, there are overheads involved in using an abstract data type (implemented as an object class) like this.
Another method is to use DBMS_SQL to create dynamic code (SQL or PL/SQL) - and perform dynamic binding (the bind determines the data type of the bind variable in the code). If the dynamic code is a SQL select, the describe interface enables you to determine the content (columns and data types) of the SQL projection.
The final method that comes to mind is using a RTTI (Run Time Type Information) interface - something that is also supported by Oracle (and basically the backend implementation of answering a describe interface call). This is however a bit more complex and quite specialised and needs a very unique problem to justify it being used. -
How to get values from a stored package variable of type record ?
Sir,
In my JClient form, I need to get values from a database stored package variable of type record. And the values are retained in the JClient form for the whole session. The values are copied only once when the form is started.
What is the best way to do that ?
Thanks
StephenStephen,
not sure what your model is, but if it is Business Components, I think I would expose the properties as a client method on the application module. This way all JClient panels and frames will have access to it. You could use a HashMap to store the data in teh app module.
If JDBC supports the record type, then you should be able to call it via a prepared SQL statement. If not, you may consider writing a PLSQL accessor to your stored procedure that returns something that can be handled.

Transaction Type field not getting value in F-05 transaction
Hi All,
When ever we are doing a reverse posting for foreign currency valuation using F.05 Tcode it will create a BDC session where we can execute this batch Input session thru SM37.
This will use F-05 Tcode to post the the entries, but the problem is one of the field Transaction Type is not getting value for some of the GL account numbers range. This is totally SAP standard program take cares of it. Transaction type field value shuld be populated by '990' value for this GL account range, this is fixed. So is thr any User exit or Screen exit for this Tcode or how we can populate the value....

Edited by: Bala Chandar on Feb 12, 2009 1:33 PMHi Mr/Mrs Bala Chander,
I am having the same problem.
When running F.05 a BIM is created for GL account X. GL account X has a field status in which transaction type is defined as a required field because of BCS / ECCS. We have a substitution rule in place which should default the transaction type, based on several criteria. But when executing the BIM, I see that nothing is filled in field transaction type. Did you find a proper solution for your problem? Changing the field status is not an option in my opinion.

How works Get Property Value / Type Automatic?
Hi,
I need to get in Labview some variables from Teststand. The VI I wrote use "Get Property Value" from Teststand and works fine... when I specify the type of variable I whant from Teststand (Boolean, I32,...).
But I need a VI which retrieve the value of my variable independently of the variable type.
I tried to set the type option "Automatic" but the "Get Property Value" always give back an empty array of boolean....
How works the "Automatic" option by the "Get Property Value"?
Is there a possibility in Labview to get the type of a Teststand variable?
Cheers,
RisottoRisotto,
the "automatic" feature is no feature but an entry made because of the
polymorphic design of the "get property value" VI. if you would change
the order of the VIs contained in the polymorphic VI, you would
retrieve other kind of values.
therefore never use the automatic setting of this VI. the
simplest way to solve such thing is to pass the data in variant and an
additional numeric value for identifying the type of the value.

How to get value from ___.co.xml ???
Hi All,
I am trying to deveop a KM service that should be configurable(by the User) so that he/she can specify the folder on which the service should act on...
I have created a CM repository called "<b>test_Rep</b>" for my purpose and added my rep. service to it. Guess what! The uploaded documents are getting renamed .. HURRAY!!!!!!!!!
i changed the
___.co.xml
and
___.cc.xml
files by adding another parameter!
After editing the XML files, i have tried to read the properties in the received() method as follows :
String repositoryPath = this.properties.getProperty("myFolder");
<b>It works!</b>
Original value of myFolder (in co.xml file) = /test_Rep/folder1
<Configurable .....>
<property name="myFolder" value="/test_Rep/folder1" />
</Configurable>
But, in PORTAL when i change, System Admin >> System config >> Content management >> rep. services >> com.test.SampleService >> myFolder = <b>"/test_Rep/folder2"</b>, and try to check in that folder... it doesn't work ..
I even restarted the server .. but, doesn't help!
<b><u>Doubts:</u></b>
1) when the user changes the value of 'myFolder' (in content mgt >> rep. services >> com.test.SampleService), does it change the XML file inside the par file?????
2) How should i retrieve the value of this parameter at runtime (the latest value which the user entered in content mgt >> rep. services >> com.test.SampleService)
please see the below code of received(IEvent event) method:::::
private static final Location log = Location.getLocation(SampleService.class );
public void received(IEvent event) {
IResourceEvent myEvent = (IResourceEvent) event;
IResource resource = (IResource) myEvent.getParameter();
String repositoryPath = this.properties.getProperty( "myFolder"); //getting folder name at runtime!!!!!!!
String parentPath = "";
try {
parentPath = resource.getParentCollection().getRID().toString();
} catch (AccessDeniedException e1) {
e1.printStackTrace();
} catch (ResourceException e1) {
e1.printStackTrace();
if (resource != null && (!resource.isCollection()) ) {
try {
/* my business logic...
} catch (NotSupportedException e) {
log.errorT("Got exception: Not Supported Exception!" );
} catch (ResourceException e) {
log.errorT("Got exception: Resource Exception!" );

Any ideas on this scenario ..
Regards,
Krish.Hi,
you don't have to create a ConfigListener. But if you want it - you can. Have you noticed in another sections of CM configuration that you do not have to restart the J2EE to apply changes?
In your *.cc.xml you can define it by adding the <i>hotReload, hotLoad, hotUnload</i> attributes. See my example:
<ConfigClass
id="name"
name="NewDocuments"
hotReload="true"
hotUnload="true"
advanced="false"
hotLoad="true"
configurable="cz.sap.szif.newDocuments.handler.EventHandlerService" >
<attribute name="name" type="string" mandatory="true" visibleColumn="true"/>
<attribute name="replicator" type="boolean" mandatory="true" default="false"/>
</ConfigClass>
Now create an implementation of IConfigListener interface (something like this):
public class NewDocumentsServiceConfig implements IConfigEventListener {
// plugin definition
private static final String PLUGIN_NEW_DOCUMENTS = "/cm/customer";
private static final String CONFIGCLASS_NEW_DOCUMENTS = "NewDocuments";
private static final String readPlugins[] = { PLUGIN_NEW_DOCUMENTS };
// config data
private List configList = null;
* constructor
public NewDocumentsServiceConfig() {
try {
// read initial data
reconfigure();
// register event listener for my configuration
Configuration.getInstance().getConfigEventServiceInstance().addConfigEventListener(
this,
readPlugins);
} catch (Exception e) {
LogWriter.traceSevere(LogWrapper.trace, e, LogWriter.extractCallStack(e), true);
* call before object destroy
public void destroy() {
try {
// unregister listener
Configuration.getInstance().getConfigEventServiceInstance().removeConfigEventListener(this);
} catch (InitialConfigException e) {
LogWriter.traceSevere(LogWrapper.trace, e, LogWriter.extractCallStack(e), true);
} catch (Exception e) {
LogWriter.traceSevere(LogWrapper.trace, e, LogWriter.extractCallStack(e), true);

public void configEvent(ConfigEvent event) {

// ...you could catch which configuration was changed and only change the config for only this one
try {
if (event.getType() != ConfigEvent.CONFIGURABLE_LOADED
&& event.getType() != ConfigEvent.CONFIGMANAGER_TERMINATED)
reconfigure();
LogWriter.traceInfo(LogWrapper.trace, " event:" + event.getType());
} catch (Exception e) {
LogWriter.traceSevere(LogWrapper.trace, e, LogWriter.extractCallStack(e), true);
* Reload all the configurations
private void reconfigure() {
try {
IConfigClientContext context = IConfigClientContext.createContext(ConfigCrutch.getConfigServiceUser());
IConfigManager cfg = Configuration.getInstance().getConfigManager(context);
IConfigPlugin configPlugin = cfg.getConfigPlugin(PLUGIN_NEW_DOCUMENTS);
this.configList = new LinkedList();
if (configPlugin != null) {
LogWriter.traceInfo(LogWrapper.trace, " configPlugin:" + configPlugin.getName());
IMutableConfigurable[] configurables =
configPlugin.getConfigurables(CONFIGCLASS_NEW_DOCUMENTS, false);
for (int j = 0; j < configurables.length; j++) {
IMutableConfigurable configurable = configurables[j];
if (configurable.getConfigClass().getName().equals(CONFIGCLASS_NEW_DOCUMENTS)) {
// this is a simple object which holds the attribute values
// in a HashMap (hMap.put(PROP_NAME, configurable.getPropertyValue(PROP_NAME));...)
NewDocumentsConfigRecord record = new NewDocumentsConfigRecord(configurable);
this.configList.add(record);
} else {
LogWriter.traceWarning(
LogWrapper.trace,
" configPlugin == NULL for pluginName:" + PLUGIN_NEW_DOCUMENTS);
} catch (InitialConfigException e) {
LogWriter.traceSevere(LogWrapper.trace, e, LogWriter.extractCallStack(e), true);
} catch (Exception e) {
LogWriter.traceSevere(LogWrapper.trace, e, LogWriter.extractCallStack(e), true);
* @return all my configurations
public List getConfigList() {
return this.configList;
...and in your service:
public class EventHandlerService extends AbstractService implements IEventHandlerService {
private NewDocumentsServiceConfig config_listener;
public void afterInit() {
// setup config listener
config_listener = new NewDocumentsServiceConfig();
public void release() {
config_listener.destroy();
config_listener = null;
Now you should be able to catch the changes in the configuration.
Hope this helps,

Creating a simple type in runtime
Hi,
I'd like to know if it's possible to create a simple type in runtime, and set its constraints.
I need to do that because I generate UIElements at runtime, and I'd to parameter the type of the attribute bound to that UIElement at runtime.
I won't know the number of UIElements and their type definitions until I go get them from the backend.
Is it possible, or I'll have to resolve that through a workaround?
Thanks in advance.
Alexis TrudeauHi Alexis,
it's not possible to create a SimpleType at runtime, but it is possible to modify one. Everything can be changed except the builtin-type, which basically describes the Java class used to store values for this type.
So you can create your attributes using the predefined SimpleType for your desired class and then call
getModifiableSimpleType()
on that attribute. Then you can set the constraints as needed.

These exceptions probably refer to dataset (query) parameters rather than to report parameters because of their numbers and total amount.
The first exception "Cannot set preparedStatement null" seems to be thrown for all parameters that are initially nulls. The second exception "Cannot get parameter type" seems to be thrown for all parameters (twice for some).
The second one probably has something to do with this bug: https:\//bugs.eclipse.org/bugs/show_bug.cgi?format=multiple&id=384925 Although it is declared to be fixed in an earlier Birt runtime version (4.2.1) and I'm using a later one (4.4.2).
The first one gets critical if I change the Oracle jdbc driver to the new and the most appropriate one (ojdbc7.jar), which should be a better choice because I have Java 7. Older driver ojdbc6.jar renders the report but writes the exception to the logfile, the newer one produces the following in browser:

The exceptions raise even in such a simple case. Of course it doesn't take minutes to show, but concerning my report with several datasets taking more than 200 parameters in total, the response time drastically raised from about 30-40 seconds up to 3 minutes.
So I need help!Hello,
Were you able to solve this problem and how?
Thanks -
Getting values from a stored procedure with no parameters
Hi,
I'm trying to get values out of a stored procedure that I created on SQL server. I'm trying to get XML values out of the database, but I'm not sure how to get any data out of it written to a file if the procedure doesn't have any parameters.
So I'm just making a call:
CallableStatement cs = conn.prepareCall("{call myproc}");
cs.execute();How do I get values back from this stage?
Thank you very much,
LiorThe short form answer, which assumes that the stored procedure is returning the XML as an out parameter would go something like this.
public void build(String newUserID, String newPassword) throws SQLException {
String sql = "{ call GET_ITEM_DETAIL(?, ?, ?, ?, ?, ?) }" ;
try{
init(newUserID, newPassword) ;
setCallableStatement(getConnection().prepareCall(sql)) ;
getCallableStatement().setInt(1, getItemNumber()) ;
getCallableStatement().registerOutParameter(2, oracle.jdbc.driver.OracleTypes.CURSOR) ;
getCallableStatement().registerOutParameter(3, oracle.jdbc.driver.OracleTypes.INTEGER) ;
getCallableStatement().registerOutParameter(4, oracle.jdbc.driver.OracleTypes.VARCHAR);
getCallableStatement().registerOutParameter(5, oracle.jdbc.driver.OracleTypes.VARCHAR) ;
getCallableStatement().registerOutParameter(6, oracle.jdbc.driver.OracleTypes.VARCHAR) ;
getCallableStatement().execute() ;
setSqlResult(getCallableStatement().getInt(3)) ;
setSqlMessage(getCallableStatement().getString(4)) ;
if( getSqlResult() != 0 ){
throw new SQLException(getSqlMessage(), null, getSqlResult()) ;
setResultSet((java.sql.ResultSet) getCallableStatement().getObject(2)) ;
if( getResultSet() != null ){
while( getResultSet().next() ){
setItemType(getResultSet().getString("ITEM_TYPE")) ;
setItemValue(getResultSet().getString("ITEM_VAL")) ;
setDisplayType(getCallableStatement().getString(5)) ;
setDisplaySize(Integer.parseInt(getCallableStatement().getString(6))) ;
catch(SQLException e){
java.util.Date now = new java.util.Date() ;
java.text.DateFormat format = java.text.DateFormat.getInstance() ;
setSqlMessage( e.getClass().getName() + " : " + format.format(now) + " : " + e.getMessage() + " : IN " + getClass().getName() ) ;
System.err.println(getSqlMessage()) ;
throw e ;
finally{
closeResources() ;
}The GET_ITEM_DETAIL stored procedure returns several out parameters of various types. The code registers them as out parameters along with an anticipated type and then calls the getXXX(n) method that corresponds with that data type in the appropriate position.
As I mentioned in my other post, the onus of returning the XML is on the stored procedure, when you get it into Java it's going to be a java.lang.String that you can then parse by whatever means is appropriate to your situation.

Help: cant get values from a resultset
i have a class that contains all my MySQL statement and i am trying to use the results found from one of my select statements to pass on into another class which displays the results in a gui form. Here is my query:
public void profile(String user)
try
Class.forName(driver);
Connection con = DriverManager.getConnection( url,db_user, db_pass);
String username, name, email, dob, bio, gender, homepage, number;
//find username and select all details
String find = "SELECT Username, Full_name, Email, dob, Biography, Gender, Homepage, Contact_number FROM users WHERE Username = ? ";
PreparedStatement ps1 = con.prepareStatement(find);
ps1.setString(1, user);
ResultSet rs = ps1.executeQuery();
while(rs.next())
//retreive information from the server
username = rs.getString(1);
name = rs.getString(2);
email = rs.getString(3);
dob = rs.getString(4);
bio = rs.getString(5);
gender = rs.getString(6);
homepage = rs.getString(7);
number = rs.getString(8);
User_Profile profile = new User_Profile(username, name, email, dob, bio, gender, homepage, number);
JOptionPane.showMessageDialog(null, username + bio + email, null, JOptionPane.ERROR_MESSAGE);
con.close();
catch( Exception e )
e.printStackTrace();
JOptionPane.showMessageDialog(null, "error," + e.getMessage(), null, JOptionPane.ERROR_MESSAGE);
}As you can see, i am trying to pass on the variables username, name, etc to a new instance of my user_profile class but it doesnt for some reason. i dont get any comple errors so thats ok. i created messege dialog box from within the while statement above to see if a value is stored, and yes their is a value stored in my variables
below is the user profile class which shows my constructor that suppose to get the values from the query class in this code entered above User_Profile profile = new User_Profile(username, name, email, dob, bio, gender, homepage, number);
protected String username;
protected String FullName;
protected String Email;
protected String DOB;
protected String Biography;
protected String Gender;
protected String Homepage;
protected String Con_Number;
protected String crnt_user;
public User_Profile(String user, String name, String email, String dob,
String bio, String gender, String homepage, String number)
initComponents();
addWindowListener( this );
//get values from sql query and store them here.
this.username = user;
this.FullName = name;
this.Email = email;
this.DOB = dob;
this.Biography = bio;
this.Gender = gender;
this.Homepage = homepage;
this.Con_Number = number;
}the code below is used to display one of the values received from the query class, in this case returns null..
txt_name.setText(username)Does the user String match the database String
exactly?
Some databases are case sensative.Sorry posted before done.
Also, ensure you do not have trailing spaces in one or both. I remember Oracle had this problem a few years ago using the Type 4 driver but not through ODBC.
