Generating Class at Runtime

hi
can anyone tell me how to generate Classes at run time ,
the requirement is such that given the name of the methods , and attributes the class is generated ,
thanks in advance
Abhishek

Hi Abhishek,
I think you can use function module SEO_CLASS_CREATE_COMPLETE though I have never used it..
Just do a where-used list on the fm and see how is it called.
Hope this helps..

J2SE 1.4 generated classes on older JRE versions

Maybe a newbie topic but is it normal that JDK 1.4 generated classes only work on the JRE 1.4 runtime environment ?
If so, how do I compile to work on older runtime environments ?
A link to a page with info on this would be most appreciated...

Thanks,
That was the link I was looking for.
FYI : To make my applet run with the default JVM for Internet Explorer I had to compile to target 1.1 and strip the code from all Java 2 code. Strange, as I have IE 6.0 and you would expect it to come with a Java 2 runtime...
Anyway, my first applet is on the Net now : http://www.ebo.bewoner.antwerpen.be/Shift/Game.html .
I wonder if it works from other clients than mine...and especially other machines that a Windows PC !

Syntax error for automatic generated class for object MAS_AUTH_CUST

Hi,
I am configuring the mobile sales scenario. I encountered a weird problem. Basically the automatically generated class ZDOECL_013_00H_MWSR can not be activated. If you activate it manually it will give you the below error. Looks like the entity structure is too big. So the generated code has a very big loop which causes the dump. I found the issue when try to run the function module CRM_AUTH_CUST_INSERTCDS as suggested in the configuration guide.
I have tried to regenerate the object. But it still give me the same error.
Internal error occured during runtime generation of Class ZDOECL_013_00H_MWSR (Dump ID: GEN_BRANCHOFFSET_LIMIT_REACHED)
Message no. OO053
Diagnosis
An internal error occurred when the system tried to generate the runtime objects of the class. A dump has been created with the given dump ID. It can be analyzed using transaction ST22.
Our Netweaver version as below. It should contain already the latest patch etc.

How to extend/ replace generated classes from JAXB

Hello Experts,
In our application (Which uses Java Webdynpro as the UI and RFCs for the backend access- an R/3 System), there is a need to construct an XML file (from the data entered by the user) which will be later accepted by the backend system. Now to avoid manual creation of the XML document, what we did is that we created an XSD file based on the back end structure (This XSD contains definition for all the possible fields and structures in the back end).
Then we used the JAXB implementation to automatically create Java Objects from the XSD file. We populate this JAXB generated Java objects and then use the Serialization framework to serialize them into an XML file.
This all works well, provided that the structure of the back end system does not change, but unfortunately it can, customer can add additional attributes to the existing structures (They do not create new structures, just add new attributes to it so I do not need to create new Java Object classes at runtime, I need only to add attributes to them). If they do so, the XSD and corresponding Java Objects (which are shipped as part of the source code) do not remain valid anymore as the automatically generated Objects (which correspond to the structures in the back end) would not have the definition of the newly added attributes.
Can anyone please suggest how to overcome this limitation with JAXB.
The needed functionality is that somehow I should be able to add fields (corresponding to the customer added attributes) to the automatically created Java objects and thus pass the data in the additional attribute to the backend. (Please note that at runtime using an RFC, I can find out the current structure of the backend but the structure at the Webdynpro end (set of Java objects generated from the JAXB) is static and is a part of the code).
Any comments/suggestions could be of great help.
Thanks
Amit Kapoor

You cannot do that. TheJAVA language does not allow a class to "extend" more than one upper class.
Typically, the solution is to modify your architecture a little bit. Just use the "has a" relationship instead of "is a". That means something like that:public class MyFraisMessage
extends MyOtherClass
private FraisMessage message;
etc...You write an extension "MyFraisMessage" of your upper class "MyOtherClass", which has the JAXB generated object as an attribute. This structure is often useful, when you think you would need multiple inheritance.

How to set property classes at runtime.

Well, as the subject line says my question is plain and simple. I don't see any property for this in SET_ITEM_PROPERTY built-in.
Currently a form has 10 subclassed blocks and views. These blocks have almost similar/definite number of items. At a time only one block with its canvas will be shown to the user. Instead of using so many sub-classed objects, I would like to use only one block and canvas. Now I am looking get getting just property classes from the 10 child forms, which I am looking forward to apply to the common block and items. Any other ideas for the same also appreciated.
Thanks,
-- Raam.

I think there is no way to set property classes at runtime.
u must loop through the objects

User defined data type generated class

Hi
When defining a new data type in the local dictionary, one has to option of generating a representation class.
I have done this and indeed received the class in my app.
However, I fail to understand how I can use this class to retrieve values set in the data type.
Thank you for your assistance

Hello Y PEERY
I am not clear which context you are talking about .
Are you taking about simple type inside local dictonary ?
or
A project with data dictonary type ?
(for webdynpro only)
In both the case no need to deal with internal generated class, this is somethig which is requrired to framework itself , end developer not at all using /modifiying it.
or
Might you are dealing with EJB so in this case representation class is generated once we provide the basic(name , package etc) to it , further you can modify it according to your use.
Please clarify

Getting generated class files using the compiler api??

I am writing a compiler/IDE for java, and i use the new JavaCompiler API
(javax.tools.JavaCompiler)
i want to ask, is it possible to get the generated class file(compiled file) names??
can anyone help me with this, read at the documentation and i have no idea which one is used to do such thing..
Or is it impossible??
Thanks, please guide me on this..

don't.

yes, probably (after all, other tools can do it). Don't ask me how though, I've never had a need to.
can anyone help me with this, read at the documentation and i have no idea which one is used to do such thing..
no. Someone else reading the documentation for you won't help you any. Read it yourself, you might learn something.

Reusing JAXB generated classes for XSDs included in other XSDs

Hi,
I use xsds with jaxb in a number of related projects. To avoid duplication I've factored out commonly used elements into their own xsd in a separate project. I then include these in the xsds that need them.
I generate classes with jaxb for each project. I'm now trying to get jaxb so far as to reuse the already generated classes for the common elements.
For example: I have a general xsd Person.xsd for which I generate classes in common.xsd. I have another xsd Project.xsd that includes a reference to the Person element. When i let jaxb generate classes for Projects.xsd, it will also generate a project.xsd.PersonType and so on.
Is there any way to tell JAXB to use the existing classes? I've played around with the <jxb:javaType> bindings, but I can't get it to work yet. It gives me a "bindings not used" warning and doesn't compile. Also, if this is in fact the way to go, what do I specify as the parseMethod and printMethod attributes for the javaType element?
Thx for any help

JAXB questions should be better directed to the users list of http://jaxb.dev.java.net/
you should subscribe to the 'users' mailing list, then post a question there.
Thank you!

Namespace issue with oracg generated classes

Hi,
I'm having problems generating classes with oracg from the Java Xdk from an XML schema. All classes are generated, but do not compile. In some sources (mostly in the type classes) "public void addSomething(null.Something theSomething)" is generated as the method declaration, and that doesn't compile. When I add a targetnamespace to the xsd file, the generated sources compile (the 'null.' is replaced with 'myPackage.', but when I generate an XML document, I contains a namespace reference (ns1) like this:
<ns1:Note xmlns:ns1 = "http://www.somewhere.org">
<ns1:Form>
<ns1:Reference>
<ns1:ReferenceNbr>1</ns1:ReferenceNbr>
<ns1:ReferenceType>1</ns1:ReferenceType>
</ns1:Reference>
</ns1:Form>
</ns1:Note>
What I want is this:
<Note>
<Form>
<Reference>
<ReferenceNbr>1<ReferenceNbr>
<ReferenceType>1<ReferenceType>
</Reference>
</Form>
</Note>
How can I get this result ?
Kind regards.

Did you try adding the the XmlSeeAlso annotation to the webservice
@XmlSeeAlso({<package.name>.AccountIC.class})
This will add the schema for the data type (AccountIC) to the WSDL.
Hope this helps.

How to use JAXB generated classes with SOAP

hello,
I have a library of JAXB generated classes for my web service. There is a Java class for each web method defined in my schema. For example, my getLocation method is mapped to GetLocation.class.
However my web service is SOAP based, so I am having to manually strip off the SOAP elements to be able to unmarshall the getLocation xml to a GetLocation class.
I am noticing a disconnect between JAXB and other Java SOAP and RPC libraries. Does anyone know how to create a JAXB class for SOAP Envelopes and Bodys? Does anyone have any ideas how to incorporate the existing Java web service libraries with JAXB?
Thanks in advance.

Have you found a method to integrate SAAJ and JAXB? Or
is better to use SAAJ only ?If I had to choose I'd go with SAAJ. It seems to me that's theoretically possible to use JAXB classes with SAAJ but I imagine if it is possible it would be a big pain in the ass.

Generated Class is not called by Inbound Proxy

Uploading data to Ztable of ECC by using inbound proxy.
The messages are tranfered to SAP ECC from SAP XI.
Monitoring in SXMB_MONI in SAP XI DEV can see Success flag
Monitoring in SXMB_MONI in SAP ECC can see inbound message stored in QUEUES only.
I configured the Application Integration Engine as per the help document.
In Reciever XI Adapter set the addressing type URL.
Coding is correct in the method of the generated class.
Let me know if any configurations yet to be done.
Let me know how to proceed furthur.
ThankYou in Advance.

hi
Go to SMQR of the ECC and register and activate the queues again.
Also ensure that u are implementing the correct methods of the proxy

How to change generated class name when create binding files.

I have a dtd file, which has lines like this:
<!ELEMENT rights (
     %plain-text;
     | rights.owner
     | rights.startdate
     | rights.enddate
     | rights.agent
     | rights.geography
     | rights.type
     | rights.limitations
     )*>
     <!ELEMENT rights.type (%plain-text;)*>
when i use xjc to create binding files, I got an error:
trying to create the same field twice: value.
I suspect that the reason is because the name of rights and rights.type.
so, i'd like to know how can i control the generated class name. for example, i want to generate a class RightTypeEle for element rights.type. how can do that?
btw, i use latest version of jaxb.
Thanks in advance.

Calling Stored Procedure w/JPublisher generated classes

Hi,
We are trying to pass Oracle nested tables as input/output parameters to several of our stored procedures to support bulk binding operations in the database from our applications. We have some database defined types and stored procedures that use these as input/output parameters which have been tested and working at the database level. I managed to get JPublisher to create these classes and compile fine, but I am not sure exactly how to register these classes as parameters with the stored procedure Java call. Any assistance is appreciated.
Here is a sample of the db types/procedures:
TYPE USER_APP_TYPE IS OBJECT
    User_ID             VARCHAR2(50), -- input fields
    App_ID              VARCHAR2(50),
    App_Type            VARCHAR2(50),
    App_Obj_ID          VARCHAR2(50),
    Status              VARCHAR2(30),   -- output fields
    Desc_String         VARCHAR2(255),
    Comments            VARCHAR2(255)
TYPE USER_APP_LIST IS TABLE OF USER_APP_TYPE;
CREATE OR REPLACE
PACKAGE BODY PKG_MOD_BULK
AS
    PROCEDURE LOOKUPAPPBYUSER_BULK(
        p_InOutRS   IN OUT USER_APP_LIST)
    IS
        BEGIN
        ... do work - fill in output fields ...
        END LOOKUPAPPBYUSER_BULK;
END PKG_MOD_BULK;So using JPublisher 3 classes were generated with constructors and getter/setter methods:
UserAppType.java
UserAppTypeRef.java
UserAppList.java
My consumer POC code looks like this:
public class BulkBindingDemo
    @SuppressWarnings("CallToThreadDumpStack")
    public static void main(String[] args)
        Connection conn = null;
        try
            String UserName = "user";
            String Password = "pass";
            // Load JDBC driver
            Class.forName("oracle.jdbc.OracleDriver");
            conn = DriverManager.getConnection("jdbc:oracle:thin:@mydatabse.com:1521:mysid", UserName, Password);
            // Create instances of custom database UDT classes.
            UserAppList myAppList = new UserAppLicList();
            UserAppType[] myAppArr = new UserAppType[2];
            // Populate UDTs
            myAppArr[0] = new UserAppType("bob" ,"acct","fiscal","1FG452ABC",null,null,null,null,null,null,null);
            myAppArr[1] = new UserAppType("joe","hr","benefits","89JTYG671",null,null,null,null,null,null,null);
            myAppList.setArray(myAppArr);
            // Not sure how to set parameter as input/output.
            CallableStatement cs = conn.prepareCall("BEGIN MY_SCHEMA.PKG_MOD_BULK.LOOKUPAPPBYUSER_BULK(?); END;");
            cs.setObject("p_InOutRs", myAppLicList);
            cs.execute();
            ResultSet rs = cs.getResultSet();
            // Get results - null fields from above should be populated
            if (rs.first())
                myAppList = (UserAppList)rs.getObject("p_InOutRs");
                myAppArr = myAppList.getArray();
                System.out.println("status:   " + myAppArr[0].getStatus());
                System.out.println("desc str: " + myAppArr[0].getDescString());
                System.out.println("comments: " + myAppArr[0].getComments());
                // additional fields here..
            //MyObject[] myObjectAry = (MyObject[])p_myObjectArray.getArray();
            //cs.registerOutParameter(1,Types.CHAR);
        catch (Exception e)
            e.printStackTrace();
        finally
            if (conn != null)
            try { conn.close(); }
            catch (Exception e) {}
}So this code will compile and run up to the stored procedure call itself, but I'm not sure how to set the parameters for in/out with these generated classes. Any ideas?

Anyone? Still haven't figured this one out...
