Java Mapping Error

[Former Member]

Hi,

I'm working with Java Mapping.

Scenario is File to File (XML to XML). I've developed the java program by using DOM parser in it. I've completed everything at IR (Datatypes, Msg Types, Imported Archives, Interface Mapping) and everything at ID.

When I test in Interface Mapping, I got the following error:

Please anybody resolve this.

Thanks in advance

Hello

this error occurs because of wrong java class file version, looks like you have compiled the class file for JAVA 1.5 or higher -> XI runs on Java 1.4 AFAIK

if you are developing your mapping in eclipse open your project select your project goto Project -> Properties (or right click your project in the project explorer and then select properties)

then select Java Compiler -> select enable project spec. settings -> and set Compiler compliance level to 1.4 or lower and rebuild your project

hi krishna,

it is not able to find the java class file. did you zip the class file and then imported in to XI ??

yes Ramesh,

I've zipped the<b> .class</b> file and <b>.java</b> file and loaded into Imported Archive.

[Former Member]

hi

you dont need .java file. you only need .class file.

You have only import .class file which is zipped and call this mapping between MTs.

Hi Ramesh,

I've zipped only<b> .class</b> file.

Now I got the following error:

I didn't get u.

U mean .class file or java program.

hi krishna

<i>public static void main(String args[]){

}</i><i></i>

do we use main function in the java mapping case in XI?

just check this link

Even then I got the same error.

"Class not found" error.

Could you plz help me.

[Former Member]

hi krishna,

did you define your class in a package...

then specify the package name for the source file of class

for example

com/sap/testjava/test.class -

> you have compress the entire path and then reload into java mapping
