Converting JPEG to PNG

[Former Member]

Hi,

I have an issue with a Java Class I created, which is supposed to help convert .jpg files to .png

I used NWDS (and even tried NetBeans 6.1) to create the Java Class, exported it as a .zip file, and inported it into the integration repository. However, when I test my Interface Mapping I get the following error message:

Initially I assumed the problem had to do with an incompartible JDK and subsequently changed it, however, I am still getting the above error message.

Question:

Does anyone have a clear Step-By-Step guide on how to create Java Classes (including the code compilation) using either SAP NWDS or NetBeans 6.1 (as the error message could have something to do with the manner in which the class has been created).

Many thanks in advance,

Reuben.

1. You have to be on the same JDK version that your XI system on your NDS.

2. In your IM make sure you have used the correct imported archive.

Hi Shabarish,

Thanks for the response in terms of using the same JDK as the PI System. I do not have access to the Unix file system as yet; do you know of any other way to check what JDK version my PI system is on?

Thanks,

Reuben.

[Shabarish_Nair · Accepted solution]

in IR or ID, goto Help -> Information

You will find the version there

Thanks Shabarish - I checked the Java version of my PI system and it exactly the same version as the JDK I've installed. So, it means that the problem is more likely related to the creation of the Java Class.

Regards.

[Shabarish_Nair · Accepted solution]

yes it has to be.

Don't create ZIP file, just create Jar file from NWDS and then import it IR. I am sure it will work;)

Hi Chirag,

Thanks for the reference. I am already using Satish's guide for the over all process i.e. in terms of how to convert from JPEG to PNG. My question, however, has to do with how to create the Java Class using SAP NWDS or NetBeans 6.1 which is then imported into the integration repository, and subsequently used in the interface mapping.

Regards,

Reuben.
