Java Mapping Question

[Former Member]

Hi Friends,

I am trying java mapping for first time, after lots of effort and gr8 help from SDN guys am able to generate the class file from java program and import it into IR. I am refering the following thread,

https://www.sdn.sap.com/irj/scn/wiki?path=/display/xi/wholePayloadtoaXML+field

I wan to know is,

1)After creating class file,when we use that in mapping,does it still needs to refer to the base folder(e.g. C:/j2sdk1.4.2/bin) .?

2) From the above link, can you please suggest what should be the input .? I had configured the scenario as in the link http://www.riyaz.net/blog/xipi-java-mapping-demystified/ that deals with string.

after doin config as mentioned above.. I am gettin error as:

10:12:44 Start of test

Hi Brijesh,

No need to refer C:/j2sdk1.4.2/bin, JAVA Stack has JDK,

Genarate JAR file after testing your code,

error because the class file its doent have proper code or the input your giving to JAVA Mapping not correct.

Check once

Hi,

You need to create a jar file before importing it into imported archives.

If you are using NWDS it will be very easy for you to test the code ,create the jar file etc. work.

else remember to include the .project & .classpath files along with the .class file in the jar.

The error is because it cannot find the class you are using.Make sure you also include .project & .classpath files in the jar file.
