BAPI not working in Java Webdynpro

Hi,
My BAPI from SAP is working in Netweaver perfectly, but when I call the same with the equal parameters in Java webdynpro, no results.
I'm using following function: 'CVAPI_DOC_VIEW'.
Any idea why the BAPI is not working in Java Webdynpro?
Regards,
Tim

Hi Tim,
AFAIK 'CVAPI_DOC_VIEW' will work only in standard SAP Dynpro. Inside Webdynpro it is forbidden to save files in the background and using GUI class with execute, so you cannot use that Standard FM.
Check this thread .
Thanks

Applets not working with Java 1.7.0_51 in MII 14.0 SP4 Patch 5

Hi,
I'm currently evaluating the migration of our MII 12.0 developments to MII 14.
But I'm running in several issues just trying to use simple things like a SQL query template with an iGrid Display template in test mode.
Used versions are: MII 14.0 SP4 Patch 5 and on client side the latest Mozilla Firefox with Java 1.7.0_51
At first I always get a java security warning when the applet is being loaded about unsigned applications.
At second the applet itself is not running. It always shows "No data available" and the java console shows the following errors (iResult is the id of the applet):
iResult [ERROR] - Couldn't set query template: No Query Defined
iResult [ERROR] - Couldn't set display template: null
iResult [ERROR] - Couldn't set display template: null
Is this perhaps a general problem, that the MII applets are not working with Java 1.7.x versions?
If I call the same MII page from a client with Java 1.6.x it is working without errors.
Do you have some suggestions for me?
Regards Timo

please clear your JAVA Cache. that should solve the JRE issue. thanks

ADS configuration error - PDF form not displaying for Java WebDynpro

Hi Experts,
Sub : Problem with configuring Adobe Document Services
We have installed .. NW2004s SP12 on HP-UX OS.
As of now all the services are working fine, recently started configuring "Adobe Document Services", followed all the instructions given in the guide.
Environment :
=============
- Configuring ADS Webservice for "BASIC" Authentication, not for SSL
- Poratl (AS JAVA) and BI (AS ABAP) are running in different systems.
- Portal using UME as the data storage.
- OS is HP-UX
Configuration Check for Interactive Forms in Web Dynpro for Java
=================================================================
1. Checking the User and Password ---
http://<server>:<port>/AdobeDocumentServices/Config -- the system displays the version number of the Adobe document services in the response area.
2. Configured Webservice for Basic Authentication -- success
In the process of testing this configuration -- i've developed a Java Webdynpro interactive form and deployed into my DEV server (NW2004s Sp12).
Unfortunately, form is displaying in my sneak preview version (Nw2004s SP9), getting error when deployed into Dev server - NW2004s SP12 on HP-UX.
We haven't installed ADS separately, making use of ADS comes with the default installation.
Error :
=======
java.net.SocketTimeoutException: Reatimed out
com.sap.tc.webdynpro.clientserver.adobe.pdfdocument.base.core.PDFDocumentRuntimeException: Failed to UPDATEDATAINPDF
I found that the following directory is empty in DEV server ... /usr/sap/EPL/JC03/j2ee/os_libs/adssap/XMLFormService, but not in sneak preview version.
Please do let me know to solve the problem.
Thanks

Thanks for quick response.
Installed Reader in my PC, i can view the deployed interactive form thru sneak preview, but getting the following error when running the same application thru my development server.
java.net.SocketTimeoutException: Reatimed out
com.sap.tc.webdynpro.clientserver.adobe.pdfdocument.base.core.PDFDocumentRuntimeException: Failed to UPDATEDATAINPDF
I've installed Adobe Reader in the client PC not is the server system.

Dynamic configuration not working in Java mapping

Hi All,
I have a scenario where i am using java mapping. In this i am doing following
1)Read file name from input message header
2)set file name in output message Header
3) set Directory name in output message Header
i have used following code .. but iit is not working... when i test end to end... in reciver communication channel it is failing stating " message failed as "Directory is not set in Header. Also i checked in SXMB_MONI "dynamic configuration".It is not showing Directory.
this is code.
public void transform(TransformationInput transformationInput,TransformationOutput transformationOutput)
               throws StreamTransformationException {
               private Map para;
               String Directory ;
               String inputFileName;
               String var1 = "ABC";
               para = transformationInput.getInputHeader().getAll();
               DynamicConfiguration conf = (DynamicConfiguration) para
                         .get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
               DynamicConfigurationKey keyFileName1 = DynamicConfigurationKey
               .create("http://sap.com/xi/XI/System/File", "FileName");
                     inputFileName = conf.get(keyFileName1);
               DynamicConfigurationKey keyFilename = DynamicConfigurationKey
                         .create("http://sap.com/xi/XI/System/File", "FileName");
               DynamicConfigurationKey keyDirecory = DynamicConfigurationKey
                         .create("http://sap.com/xi/XI/System/File", "Directory");
               Directory = "tmp/"+var1;
               conf.put(keyFilename,inputFileName);
               conf.put(keyDirecory, Directory);
I am in PI 7.1 ,   and in eclipse its showing warning that Para is not used.
Can anyone show some lights.
Also is there any way to debug this?? like is there any function by which i can write the trace for each step to see those in MONI.

Method name:   public void createDirectory(Resultlist result, Container container)throws StreamTransformationException
//Use Simple UDF and do the following lines
String Directory ;
String inputFileName;
String var1 = "ABC";
DynamicConfiguration conf = container
    .getTransformationParameters()
    .get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey keyFileName1 = DynamicConfigurationKey
               .create("http://sap.com/xi/XI/System/File", "FileName");
inputFileName = conf.get(keyFileName1);
DynamicConfigurationKey keyFilename = DynamicConfigurationKey
               .create("http://sap.com/xi/XI/System/File", "FileName");
DynamicConfigurationKey keyDirecory = DynamicConfigurationKey
               .create("http://sap.com/xi/XI/System/File", "Directory");
Directory = "tmp/"+var1;
conf.put(keyFilename,inputFileName);
conf.put(keyDirecory, Directory);
and remove these 3 lines
//private Map para;
//para = transformationInput.getInputHeader().getAll();
//DynamicConfiguration conf = (DynamicConfiguration) para.get(StreamTransformationConstants.DYNAMIC_CONFIGURATION
>>I am in PI 7.1 , and in eclipse its showing warning that Para is not used.Can anyone show some lights.
You can simply remove declaring Map Para line... The eclipse gives warning because you dont assign values for it and you are trying to use...
For using the same input file name in output side, you dont need coding ... you need only for the directory...

{@inheritDoc} not working for Java Classes

Hello,
i am using {@inheritDoc} for inherting super class's JavaDoc for a perticular function..
It is working, if super class is my own class. i am able to see all JavaDoc in child class.
But when i use {@inheritDoc} for extending JavaDoc of java class it is not working.
i.e. if i am writing {@inheritDoc} in public void actionPerformed(ActionEvent e) method..
It wont show any javadoc..
How to add it? Do i need to give source of java classes too???
And if it is Yes, then where to specifiy. and where to find source of Java classes, do they come with JDK? or NetBeans?? (If yes then where it is in JDK or Netbeans???)
Thanks,
Nachiket.

Yes, you need to have the Java source, with the -sourcepath option, as described here:
Inheriting Comments from J2SE - Your code can also automatically inherit comments from interfaces and classes in the J2SE. You can do this by unzipping the src.zip file that ships with the SDK (it does not contain all source files, however), and add its path to -sourcepath. When javadoc runs on your code, it will load the doc comments from those source files as needed. For example, if a class in your code implements java.lang.Comparable, the compareTo(Object) method you implement will inherit the doc comment from java.lang.Comparable.
http://java.sun.com/j2se/javadoc/faq/#incrementalbuild
If you want the full Java source get it from here:

Reposting ! string concatanation not working in java

hi I am using the following code to construct a string and i see that it seems that the correct string is made but the application does not run
if i just cut n paste the same string into command prompt it works fine . please advise :

If the parameter is just one word for example say "Testing" then the shell command works fine which tells me that the string concatanation is not working or embedding some special chars?

J2EE_ADMIN not working in Java Side

Hi All,
The J2ee_admin Id is not working on the Java side, but is working on the ABAP Side. I changed the password of SAPJSF, is it bcoz of that? If yes, pls suggest what can be done.
Regards,
Divya

Hi Divya,
You can Activate the Emergency User (find the directions at http://help.sap.com/saphelp_nw04/helpdata/en/3a/4a0640d7b28f5ce10000000a155106/content.htm ).
The you can login using the SAP* account. After which you can go in to the User Administrator and update the j2ee_admin account password. Then logout, disable the Emerengy User (SAP*), and login using the j2ee_admin account.
hope this would resolve your issue. If still it persists, do revert.

SDM still not working with Java v6u15

I keep waiting for Java to work some day with their updates on Cisco SDM. Update 14 at least allowed SDM to open. But the new update 15 still hasn't passed the test of clicking on the Configure button and then the Additional Task button. It just doesn't do anything. If it is something that Cisco can fix, please be aware.
Thanks,
.. Jim ..

Hi Jim, you need to downgrade the JAVA version on the computer you want to use SDM.
SDM does not support java after: 6u3.
Cisco SDM requires Sun Java Runtime Environment (JRE). The following versions are supported:
â¢JRE 1.5_09
â¢JRE1.4.2_08
â¢JRE 1.5.0_06
â¢JRE 1.5.0_07
â¢JRE 1.6.0_02
â¢JRE 1.6.0_03
As per the release notes.
http://www.cisco.com/en/US/docs/routers/access/cisco_router_and_security_device_manager/software/release/notes/SDMr25.html
This will resolve your issue.
Cisco does not plan to fix this as SDM is end of life.
The product that replaces SDM is CCP: Cisco Configuration Professional, that one works with JAva 6 update 14, but it's a different product. It's also a freeware you can download from our website.

Mapping editor not working with Java 5 classes

I have a small protoype web service which I wrote using Tomcat/Axis/Spring/Hibernate and using EJB3 annotations for the mappings. I want to port the persistence layer to Toplink.
I installed Toplink 9.0.4.1 and added the toplink libraries to my project and implemented the DAO and the spring bean defs.
I opened the mapping editor and created a project. When I try to add classes to it for mapping I get an error that it can't find the classes (even though I selected them from the chooser). I figured it might be that they were compiled with Java 5, so I switched the JRE_HOME in setenv.cmd to my Java 5 JRE. Now I can import the classes and see the attributes but when I click on any of them in the Navigator panel, the editor panel remains blank. If I now try to save, I get:
java.lang.NullPointerException
     at oracle.toplink.workbench.ui.tools.CheckListModel.getRowCount(CheckListModel.java:119)
     at javax.swing.JTable.checkLeadAnchor(JTable.java:2949)

     at oracle.toplink.workbench.ui.tools.CheckList.initialize(CheckList.java:47)
     at oracle.toplink.workbench.ui.tools.CheckList.<init>(CheckList.java:26)
It seems that the mapping workbench doesnt work with Java 5. What should I do?

Ah, I see. I saw another post here stating that must use 10.1.3.

Why is creation of a service notification using BAPI not working?

I need to create a service notification.
I have found 2 BAPIs.
BAPI_SERVICENOTIFICAT_CREATE

The code below using the second BAPI is not creating a notification and the return parm does not have any errors.

Xerces for XSD 1.1 Validation not working in Java Mapping

Hi Experts,
We are trying to use XSD 1.1 (assertion feature) validation for the XML payload in a Java mapping program. But I am getting the following exception:
java.lang.IllegalArgumentException: http://www.w3.org/XML/XMLSchema/v1.1 at javax.xml.validation.SchemaFactory.newInstance(SchemaFactory.java:186)
This is happing for the statement:
SchemaFactory factory = SchemaFactory.newInstance("http://www.w3.org/XML/XMLSchema/v1.1");
The reason (apparently) is because it is not able to instantiate the class org.apache.xerces.jaxp.validation.XMLSchema11Factory , which is the Xerces implementation of the SchemaFactory class.
I have tried following things so far -
1. If I try to validate an xml against an xsd 1.1 schema in a standalone program, it works perfectly fine.
2. If I try to deploy this whole functionality on to the server through an EAR (like an adapter module), there again it works.
3. Also tried this before instantiating the SchemaFactory -
System.setProperty("javax.xml.validation.SchemaFactory:http://www.w3.org/XML/XMLSchema/v1.1","org.apache.xerces.jaxp.validation.XMLSchema11Factory");
4. I tried by creating the Imported Archive objects for all the Xerces jars that we require for validation, within the same SWCV, namespace. But still I get the same exception as above (IllegalArgumentException)
5. The link [http://help.sap.com/saphelp_nw70/helpdata/en/b6/8097f5a5edea4f8dfc87ac87082b22/content.htm ] mentions that we need to place all the necessary jars at location <SAP_J2EE_Engine_install_dir>/cluster/server/bin/ext /. But even after placing the jars there, I get the same exception.
I am not sure how we need to handle this. Has anybody faced a similar situation? Any suggestions?

Hi Stefan,
Thanks for the reply.
We are on PI 7.1 SP 06. The standard XML tools from jdk supports only XSD 1.0, as far as I know. And XSD 1.0 does not have the Assert feature (also known as, co-occurrence constraint). More details are provided here - [http://www.ibm.com/developerworks/library/x-xml11pt2/]
To use XSD 1.1, we need a different implementation like Xerces-J. I am not sure how we can use it without external jars. I would like to mention again that I could achieve this by using an adapter module (EAR containing the jars), but I need to do this in Java Mapping (imported archive).
Do you know how we can achieve this in any other way? Any other suggestions welcome.
Thanks & Regards,
Sudheer

Delete and renameto not working in java

guys, i have written a java program that reads file1 into temp file and finally writes into another file. program is working fine with no errors, it even reported that the file is deleted. But actually the file was not deleted and renameto was never successful. could you guys see any problem with file definetion so that delete is not successful. please see code from 6th line from bottm.
public class Mergewrs {public static void main (String[] args) throws IOException {
/* Creates a new instance of mergewrsFile */

guys, i have written a java program that reads file1

program is working fine with no errors, it even
reported that the file is deleted. But actually the
file was not deleted and renameto was never
successful. could you guys see any problem with file
definetion so that delete is not successful. please
see code from 6th line from bottm.Since you don't actually do anything with the return value how do you know it was successful?
