Runtime Exception from WDP generated interface class

Hi,
I am having runtime class cast exceptions from the Internal component file. There is no errors in compiling/building. The application is trying to use another method in the component in another DC. I believe some generated files may have go corrupt but i am not sure how to fix this. Anyone have any suggests? Or maybe other ideas what might be causing this.
java.lang.ClassCastException
at com.xxx.yyy.component.wdp.InternalABCComp.wdGetTestInterface(InternalABCComp.java:694)

Hi,
If this DC is using is using other components then the problem may be with the UsedDCs. Check if any one of them or their models are changed. Then you have to reimport the models in that DCs. (Hint: Build and deploy those DCs if there have problems you can find)
REgards,

Runtime exceptions from listeners

          When a servlet context listener throws a runtime exception, does the container
          catch it? It seems that
          the container just ignores the exception and tries to go on with life as usual.
          It does not even log the
          exception trace in the server log. Out of desperation, I finally put my entire
          contextInitialized() method
          in a try-block, and created a catch-block for RuntimeException which prints the
          exception stack-trace to
          the console.

How to log exception from a struts action class

Hi guys,
I am recoding my application to use the strut framework. There's one small thing i wonder is that how i can log an exception arrise in an action class. In my original servlet, wherever an exception arise, i use:
catch(Exception e)
         getServletContext().log("User enter an invalid date");
         throw e;
      }However, when i move this servlet into a action class, the getServletContext method doesnt work anymore. I thought action is a child of httpServlet but since getServletContext is not available in action, then how can i log the error?
Hope to get some help

lnthai2002Action class is just a POJO and works a handler of your request. ActionServlet invoke your Action class based on the action you call in your URL. When you are usign the Struts why do you need your Original Servel, use the ActionServlet and if required you can extend it and create your own servlet

Throwing Runtime Exceptions from BPM. How?

Hi !
I want to make appear a red flag in the SXMB_MONI as a result of a custom condition inside a BPM. I tried with the control step, but it makes no "red flag".
Should I make a transform step between 2 dummy message types with a UDF that throws the runtime exception there?? is there another way ?? We want a red flag as a result of a expired deadline while waiting a file adapter transport acknowledgement.
Thanks !!
Matias.

Matias,
As you said before you want the BPM to be errored out if it reach the deadline, am I right. In control step if u say cancel process it equivalent to logically deleting the work items, so obviously you will get an succesfull message. What I suggest you to do is in Deadline branch - control branch select throw exception. The exception name has to be defined in Block level. So if you throw an exception it will look for the exception branch in the same block level if not the higher(super)block level, if it couldn't find the exception branch it will run out to error. Actually the exception branch is used to catch that exception and continue the rest of the process, so i think there is no need for defining the exception branch itself.
Hope it helps you!!!
Best regards,
raj.

Proxy class sometimes generate bean class by webmethod name

Hi,
I have designed a wrapper for my proxy classes for our project Web logic integration into Siebel
I found that during generation of proxy classes, the generated proxy class contain a bean class which is named same as the exposed web service method name, which I use to get the parameter name of method thru reflection from this generated bean class. But sometimes it doesn't generate this bean class at all, i don't know the reason why it does so.
Can any one let me know why this happens so,or is there any way that i can get this bean class in the name of exposed web service method name get generated always.
Also I want to know how to keep generated the webparam annotation for the for the exposed webemethods> Is that controlled by the web service provider?
Thanks

It depends on the service style used by the WSDL, the class wrapping the webservice operation is generated only for document literal wrapper style.

Can't fill ByteArray in EJB-Method with generated Model-Class from WD-Model

Hello everybody,
i try to call an ejb-method with data from an FileUpload-UI-Element in WD. The EJB-Method is receiving the byte-data to create a document in KM via a Web-Service.
The ebj-methid has the following signature:
public FObject putFileDataSimple (byte [] btContent, String fullFileName, String username, String password)
After importing the Model and creating a context node i have the following structure:
Request_X_putFileDataSimple
+---btContent (Node)
      +-- item
+ fullFileName
+ username
+ password
btContent is of the generated Type Byte_Item, which is itself a generated Model-Class of modelClassType ARRAY
item is of Type byte
But i simply have problems to fill the context node (or the binded model-object). i tried different ways and looked at thread [https://www.sdn.sap.com/irj/scn/thread?messageID=1954223] but i cant get it work.
So my Method in WD looks like this to fill the structure and start the ejb-method:
public boolean putKMDataSimple( com.sap.tc.webdynpro.services.sal.datatransport.api.IWDResource fin ) {
try
wdContext.currentRequest_X_putFileDataSimpleElement().setFullFileName("abc");
wdContext.currentRequest_X_putFileDataSimpleElement().setUsername("def");
wdContext.currentRequest_X_putFileDataSimpleElement().setPassword("xxx");
byte[] buffer = new byte[1];
InputStream in = fin.read(false);
int i = 1;
int j = 0;
while (i!=-1)
     i = in.read(buffer);
     if (i!=-1)
       Byte_Item bi = new Byte_Item(mAlf);     // mAlf ist global defined Model-Class-Instance
       bi.setItem(buffer[0]);
        wdContext.currentRequest_X_putFileDataSimpleElement().modelObject().addBtContent(bi);
wdContext.currentRequest_X_putFileDataSimpleElement().modelObject().execute();
Doing this results in Error-Messages like:
Model-Object is not a complex type for every byte added this way.
And finally an IllegalArgumentException at java.lang.reflect.Array.set(Native Method)
The second way i tried is:
public boolean putKMDataSimple( com.sap.tc.webdynpro.services.sal.datatransport.api.IWDResource fin ) {
try
wdContext.currentRequest_X_putFileDataSimpleElement().setFullFileName("abc");
wdContext.currentRequest_X_putFileDataSimpleElement().setUsername("def");
wdContext.currentRequest_X_putFileDataSimpleElement().setPassword("xxx");
byte[] buffer = new byte[1];
ArrayList<Byte> btlist = new ArrayList<Byte>();
InputStream in = fin.read(false);
int i = 1;
int j = 0;
while (i!=-1)
     i = in.read(buffer);
     if (i!=-1)
          btList.add(buffer[0]);
wdContext.currentRequest_X_putFileDataSimpleElement().modelObject().setBtContent(btList);
wdContext.currentRequest_X_putFileDataSimpleElement().modelObject().execute();
Trying so results in:
java.lang.ClassCastException: class java.lang.Byte:null incompatible with interface com.sap.tc.cmi.model.ICMIModelClass:library:com.sap.tc.cmi(at-sign)[email protected]@alive
whenn calling the setBtContent Method
I don't what to do now to fill the context/model-object the right way.
Any helpfull hints are very welcome

Ok Vesselin and thanx for your idea,
so i adapted the source in the way you told like the following:
                 ArrayList<Byte_Item> btlist = new ArrayList<Byte_Item>();
                 byte[] buffer = new byte[1];
                 InputStream in = fin.read(false);
                 int i = 1;
                 int j = 0;
                 while (i!=-1)
                      i = in.read(buffer);
                      if (i!=-1)
                           // Byte gelesen
                           Byte_Item bi = new Byte_Item(mAlf);
                           bi.setItem(buffer[0]);
                           btlist.add(bi);
                           j++;
                 wdContext.currentRequest_X_putFileDataSimpleElement().modelObject().setBtContent(btlist);
                 wdContext.currentRequest_X_putFileDataSimpleElement().modelObject().execute();
This results also in the following Exception when exceuting the WS-proxy:
execute

Hi Askok. This exception usually means that the weblogic server's environment
doesn't have all it needs to make the jdbc connection you want. You should
ensure that the OS environment variable PATH has all the libraries you need
for making a jdbc-odbc connection, and that it's classpath also contains the
driver you want.
What DBMS are you connecting to? The reason I ask is because if there is a
pure JDBC driver for it, that will be preferable, because the jdbc-odbc bridge
from Sun is not threadsafe, so it can corrupt Weblogic.

Runtime Exception in Creating DataSink from Applet

Hi All
I am capturing screen and recording audio using JMF utilities. The application is working fine in applet viewer but as soon as I run the application from browser, a runtime exception is thrown while creating the datasink. The exact exception is "*create the DataSink: java.lang.RuntimeException: No permission to write files from applets*".
Although I am able to create files and have set read/write permissions as well.
The jar file I am using is self signed.
Please suggest what should I do.
Thanks in advance.
Best Regards
Kuldeep

This post is made assuming that my earlier assertion is correct.

Can you please explain the root cause of this problem? Which part of my explanation are you having trouble with?

It might make it simpler if you abandon the applet and instead use a webstart launched (J)Frame.

How do I use a variable from an Interface class?

Right now I have three classes. First class is called Game and it extends my second class call Parent and also implements my third class call Source. Source is an interface class. I have a variable that I want to use in my Source class named Checker. Now, How do I go among using that variable from my Game class? What should the code look like?
ex.
public class Game extends Parent implements Source
need help badly....

ok, what I forgot to tell you guys is that my variable
in my interface class is a boolean type(true or
false). It is set to true now. But I want it to change
to false when a user triggers a button in the Game
class. How do I do this? You don't because you can't. If you have a varaible declared in an interface it must be static and final. It cannot, therefore, be changed. Better head back to the drawing board.

Hi,
The FM might be calling a dialog or bringing a GUI screen up. This would cause the Webdynpro session to disconnect abruptly.
Any conversion exit, GUI screen,dialog popup, transaction handling..etc would cause the webdynpro to disconnect. So you cannot use all FM's as it is.

How to omit xmlns from generated Java classes

Hi,
I'm using JAXB and xjc to generate Java classes from xsd fils. I've noticed that when marshalling these Java classes to XML string, there are few xmlns attributes that (as far as I concern :-))
"waste" space on the generated xml (space is critical resource in our application). Is there a way to order the Marashaller to omit these xmlns attributes from the generated files?
I tried to edit the generated xml string. I removed the xmlns attributes, but unmarshall it back to Java objects failed...
Thanks for any help,
Barak.

If the xmlns is specified in the xsd, it is also required in the xml. If you do not want it, however you can remove it from your xsd and then generate your xml

Generating JAXB classes from XSD

I am generating java classes using JAXB binding from XSDs. I organized the classes into 2 packages say package1 and package2
The XSD to create the package2 is dependent on package1. So I do an include package1.xsd in package2.xsd. With this I am running into an issue with JDeveloper while generating the classes. When I generate classes using package2.xsd, all package1.xsd classes are also generated in the same package. So, I have to manually delete these classes from package1.xsd and add import statements from package1 where required.
Is there a solutiion/work around available for suppressing duplicate class generation? Any help would be greatly appreciated.

About generating Java classes from XSD Schema ???

I need a powerfull tool to generate Java classes from XML Schema. I want that generated classes to have the option to validate XML(to be JAXP1.2 compliant).
I used XML Spy 5.4 but the generated classes can't validate an XML file.
Can you help me with other tools that:
- generate Java classes from XSD
- generate sample XML from XSD
- are JAXP1.2 compliant(validate a XML file with a schema)
Thanks.

You can also use Castor: http://www.castor.org
It generates classes from XML Schemas and enables data
binding without writing any line of a fuckin SAX
parser :-)I evaluated Castor and JAXB and while JAXB isn't perfect, it's got some things over Castor. Castor almost looks abandonded when I go to the site. The documentation just sort of trails off.
