Java Mapping Error

[Former Member]

Hi All,

I am getting the below error when I am testing the Interface Mapping after importing the java code with the .zip files into the Imported Archives:

Start of test

Hi Venkat,

If you just have the class saxmapfinal1 , instead of compiling it using package jmapsax, compile it without this package. When you create your jar or Zip file, to import to XI, saxmapfinal1 must not be inside a folder. For example, if you create a abc.zip file, when you open it, the content must be jmapsax, and not, jmapsax/saxmapfinal1.

If you have a class file, linked to another class. Tell me, i can have the solution. Send a feedback.

Hi,

I ran into the same problem and this thread is very helpful.

I have a bit of a version conlict now however:

While trying out some Java exercises I (randomly) downloaded NetBeans 6.5. For this I needed Java 1.5 or higher so i got 1.5.0_19.

For XI/PI however i still have JRE 1.4.2_17.

Is there an easy way out of this or do i have to downgrade to a different IDE version and get that to run on JDK 1.4.xx?

Any answers is helpful

Kind regards

Robert

You mean for development (developer studio) or for accessing the Integration Builder?

For developer studio (eclipse), in the preferences, you can set which JDK you want to use.

For the Integration Builder, in the Java Web Start options, set the Java runtime (JNLP) to use the 1.4 JDK (just unflag the other ones).

Regards,

Henrique.

jdk1.6.0 will not work. You should use the jdk version starting with 1.4 e.g. jdk1.4.10

[prateek]

Make sure that the system where u have developed the java mapping and the system where u r trying to import it has jdk version 1.4.xx and not 1.5.xx.

Hi

I think you are using the old version of JDK, Try with jdk-1_5_0_12.

LINKAGE_ERROR error occurs during the mapping.

See the SAP Note 755302

Thanks
