How to avoid Linkage Error in JAVA Mapping

Dear Experts,
I am trying to test the JAVA mapping compiled in NWDS but receiving the error
"LinkageError at JavaMapping.load(): Could not load class".
java.lang.NoClassDefFoundError: JSONXMLProject/bin/com/sap/json/ConvJson2Xml (wrong name: com/sap/json/ConvJson2Xml)
at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClassCond(ClassLoader.java:735)
at java.lang.ClassLoader.defineClass(ClassLoader.java:716) at java.lang.ClassLoader.defineClass(ClassLoader.java:537)
at com.sap.aii.ib.server.mapping.execution.MappingLoader.findClass(MappingLoader.java:195)
Following are the details:
SAP PO 7.4
SP Stack Number 05
JDK Version jdk16
NWDS
SAP Enhancement Package 1 for SAP NetWeaver Developer Studio 7.3 SP10 PAT0000
1.Created the Project , Package and then class (Included the logic)
2. Included 1 JSON Jar file into my project and the Added to build path.
3.Exported the project as Archive File and saved in desktop
4.Imported into SAP PO system as Imported Archive
5.Could not observe the JSON jar file which i used as referenced JAR in NWDS
6.Tested in OM after referencing the JAVA class and found the above error.
I have JDK 5, 6 and 7 present in my local desktop and I am trying to export the compiled code using both JAVA SE 1.6 and 1.5 in NWDS seperatly after going several discussions.
Can any one hep me with the screenshots and tell me how to include all the reference jar files in exported project..
Regards..

Dear Anand,
I did exactly as you shared. As the JSON jar has number of classes, then in OM all the Classes had to be assigned. Then the linkage error went.
But in execution , it shows a new error that all the classes of the JSON jar has to be implemented with interface StremTransformation or AbstractTransformation.
I assume in the Operation Mapping I will use only 1 class as JAVA Class. Anyway I am attaching the document with navigation.
Do we have any other alternative??
Please rename the extension of the document by remove .txt
Regards

LINKAGE ERROR in Java Mapping

Hi Friends,
I am getting LINKAGE ERROR when executing JAVA mapping as its not able to reference AbstractTransform class provided by SAP PI API.
This problem occurs in particular environment for this particular mapping. For other environments this is working fine.
I assume it has something to do with Java Library reference which is mis-configured during transport. Can anyone let me know how and where the library path is configured for Imported Achieves in SAP PI 7.1.
We are using java 1.5 for building and creating java achieves.
Many thanks,
SK

Hi Sumant,
This error occurs when the jdk version of XI server and the library version you used to develop the mapping are incompatible. Make sure you use the same version as of the server
have a look in SAP Note 755302

Getting Error in java mapping: Parsing empty source. Root element expected!

Hi Experts,
   I am using java mapping for schema validation of input message. I have followed all the standard procedures and implemented the java class in the interface mapping.
My interface mapping is like this:
OrderData --->Java Class ---SchemaValidate
                     Mesg Map ---OrderData_to_BAP --->BAPI Msg
So first I want to validate the schema of the input message. If the input message is invalid then XI should throw an exception. Then I use the actual message mapping to map the input order data to the BAPI input parameters.
In the java code I am using xerces parser.
The java code works fine when I run it as a standalone application.
The interface mapping also works fine if I don't include the java mapping. Ofcourse schema validation does not happen.
But when I test the interface mapping by including the java mapping then I am getting the error:
Call method execute of the application Java mapping SchemaValidate
Java mapping SchemaValidate completed. (execute() of SchemaValidate
com.sap.aii.utilxi.misc.api.BaseRuntimeException: Parsing an empty source. Root element expected!
What am I doing wrong? Why it is not getting the root element?
My Java code is as follows:

Hi Stefan,
   I did the code changes to return output stream and the java code works perfectly in standalone mode in my PC.
   But when I use the same in the Java mapping with XI then It throws an error "Getting Error in java mapping: Parsing empty source. Root element expected!".
My XI J2EE server has JDK1.4.3.11.
Is there any limitation of using SAX parser in XI? If Yes, then which parser should be used for schema validation in XI?
I have included the XSD file for schema validation along with class files in the .jar file. This jar file is then imported in XI repository. Is the XI engine not able to read the XSD file?
Do I have to handle reading XSD file differently? Any suggession how?
Is this parser error due to some security access?
Kindly help me! I have been struggling with this problem since 2 weeks. I will be greatfull to you if you can help me.
Thanks

How to avoid directory listing in java web applications.

how to avoid directory listing in java web applications.
That is on typing the url of the application it should not the directory listing. Welcome tag in web.xml doesnot fully solve the problem, since still the images folder etc is still accessible

I know of two ways.
If you're using tomcat and have access to the conf directory.
Edit your $TOMCAT/conf/web.xml. Find your default servlet properties and change
<servlet>
    <servlet-name>default</servlet-name>
    <servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class>
    <init-param>
      <param-name>debug</param-name>
      <param-value>0</param-value>
    </init-param>
    <init-param>
      <param-name>listings</param-name>
      <param-value>true</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>to <servlet>
    <servlet-name>default</servlet-name>
    <servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class>
    <init-param>
      <param-name>debug</param-name>
      <param-value>0</param-value>
    </init-param>
    <init-param>
      <param-name>listings</param-name>
      <param-value>false</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>And restart your server. This will affect every directory on the server, and return a 405 directory browsing forbidden error.
Another way, is to place an index.jsp inside each directory with a simple one line redirect to your applications CONTEXT_PATH.response.sendRedirect("http://yourserver/yourapp/");This will only affect specific directories which contain these index.jsp files.
Hope this helps

thanks , it is done now..
the program is compiled properly and class file is generated.
but m gettin error in mapping.
in IR i created two message type with data type as string.
and i had imported the class file and java program using Imported archives.
now in interface mapping mapping program i had selected type as Java Class.and name of java program.
but when i tested it, it is giving error as Linkage error occurred when loading class zip/PayloadToXMLField
Please suggest, M i doing some thing wrong?is any thing missing?

I am working on the SAP Netweaver STudio SP01. Do I need to load any libraries for the SAP programs ?
I am a newbie with Java. I dont get the direction to resolve this issue.
Good Day~

How to avoid JS Error in the status bar when report doesnt contain value.

Hi
Whenever the tabular report doesnt show any records for the given input parameter (parameter passed using select list item).
We are displaying error message in APex. But at the status bar, it is showing "Error" (unspecified
error).
Kindly let me know how to avoid this kind of error at status bar.
Thanks
Vijay

Hi Vijay,
Your javascript is probably trying to access one or more of the items within a displayed tabular form - the "f01", "f02" etc named items.
If your script does something like:
var x = document.getElementsByName("f01");
..rest of your code for f01 items..you can test if there are any "f01" items by doing:
var x = document.getElementsByName("f01");
if (x){
..rest of your code for f01 items..
}If there are no items, x is null, so the "..rest of your.." script will not get executed and no errors will occur.

How to send response message from Java mapping class? Please help!

Hi Experts,
I have a sync scenario
          -Req--> -
>
SOAP           XI       RFC
          <Res--     <-----
The Req message contains:
<Order>
       <Orderid>100</Orderid>
       <Desc>Extrenal Order</Desc>
       <Qty>2500</Qty>
</Order>
Response message is:
<Log>
     <LogTxt>Qty value cannot be more than 3 chars</LogTxt>
</Log>
In the XI I have to validate the input request message using a schema. For this I am writing a java mapping program using aii_map_api.jar.
My requirement is that If the input message schema validation fails then I want to send a response message back to sender.
How can I send a response message back to the sender in java mapping program?
Kindly help with sample code example.
Thanks
Gopal

Hi,
First, I think PI 7.1 has this functionality and perhaps it comes in a SP for PI 7.0 and XI 3.0. So first have a look at that before creating custom development.
Second, if you use the java mapping, you will only have access to a request or response message. I would advise using a custom java module in the module processor and insert this message in the sender communication channel. This will allow you to validate request and send a response.

How to avoid mutating error when insert or update record

Hi ,
I have one transaction table which is having some detail record under one transaction number, after the one transaction number is over by insert or update, i
want to check the total amounts of one flag should be matched on same table if it is not then give error message. But i am getting mutating error on insert or update event trigger on statement level trigger on above table.
Is there any other way to avoid mutating error to solve the above problem or some temp table concepts to be used. help me its urgent.
Thanks in advance,
Sachin Khaladkar

Sachin, here's as short of an example as I could come up with on the fly. The sample data is ficticious and for example only.
Let's say I need to keep a table of items by category and my business rule states that the items in the table within each category must total to 100% at all times. So I want to insert rows and then make sure any category added sums to 100% or I will rollback the transation. I can't sum the rows in a row-level trigger because I'd have to query the table and it is mutating (in the middle of being changed by a transaction). Even if I could query it while it is mutating, there may be multiple rows in a category with not all yet inserted, so checking the sum after each row is not useful.
So here I will create;
1. the item table
2. a package to hold my record collection (associative array) for the trigger code (the category is used as a key to the array; if I insert 3 rows for a given category, I only need to sum that category once, right?
3. a before statement trigger to initialize the record collection (since package variables hang around for the entire database session, I need to clear the array before the start of every DML (INSERT in this case) statement against the item table)
4. a before row trigger to collect categories being inserted
5. an after statement trigger to validate my business rule
I then insert some sample data so you can see how it works. Let me know if you have any questions about this.

How to avoid Quicktime error 50 and 0?

How can I avoid Quicktime error 50 and 0? Are there know problems in FCPX that will generate errors in QT?

You can probably minimize you odds of getting corrupted clips by optimizing where possible.

Tricky : how to avoid this error transparent to users ?

Hello, Oracle people !
I probably have a very common problem / question ...
We use third party application (called Kintana) that has some SQL queries referencing my custom Oracle views.
Connection to Oracle via JDBC. Some of those views are also using packaged functions residing in one custom package. So when I need to change logic, I'm recompiling just PACKAGE BODY at off-hours time in production. But when next time user runs those queries via Kintana web interface they get an error :
-- The following error is thrown by the Database:
ORA-04068: existing state of packages has been discarded
ORA-04061: existing state of package body "KNTA.OM_MISC_LIBRARY_PKG" has been invalidated
ORA-04065: not executed, altered or dropped package body "KNTA.OM_MISC_LIBRARY_PKG"
But when users refresh their screen on IE browser,
error goes away. (probably Oracle calls it again and recompiles object restoring its valid state)
I understand that how Oracle works,
but I was given a task by Manager :
"Make sure that users don't see this error !"
(some of users are VIP, CIO, VPs and other "highly important" executives)
So I tried to avoid this error but can't ...
I don't know how to restore valid state of recompile package to existing user sessions without this error being seen ...
Please HELP !!!
thanx,
Steve.

I've been reluctant to tell you this since it could have some serious side effects and performance issues but you could reset the entire session package state by calling DBMS_SESSION.RESET_PACKAGE BEFORE you attempt the calls. The problem is that it resets ALL package's state information and I'm not aware of a way to do it for a single package. Unfortunately, it doesn't appear that you can call this routine after the exception occurs. For some reason, the exception seems to have to make it all the way back to the client before Oracle will acknowledge the reset.

How to avoid Trace in applet java console???

I am using Java Plug-in 1.6.0_05 for my browser. In my applet i am using some files from other host. In 1.6 applet is printing all the information about my file locations, I want to avoid this. How I can do this.
In java 1.5 there is no such kind of problem.
Thanks
Jegan

within the Java console, you can type 0-5 for debug levels, but usually it's 0 by default, so why it prints that, I don't know.
But I doubt that you can, from your applet itself, tell the plug-in/console what to do in that regard, I think you best just live with it.
