calling an external written Java program into UDF.

[former_member219451]

Hi All,

Steps involved in calling an external written Java program into UDF :

Step 1: Save .java and .class file into folder according to package name assigned in JAVA Program.

Step 2: Covert it into compressed zipped folder.

Step 3: Create imported archives Object in SAP PI.

Step 4: Import zip file with import archive option.

Step 5: Now go to message mapping, open Functions tab.

Step 6: Now on down left hand side, you will find archives Used, open this tab.

Step 7: Add the above created imported archive into this.

Step 8: And in import instructions add the package name, you have given in above used JAVA program.

I did all these steps successfully, but after I entered package name in import instructions(Step 8),  when I activate the mapping, I got the below error.

has syntax errors: Java Area import, Line 7: package firstpackage does not exist
import firstpackage.*;
^
1 error

Please help me in this regard.

Hi Mark,

Thank you for the reply.

I tried with different namespace for Imported Archive and Message Mapping under same SWCV. But still getting same error.

Error :

Source text of object Message Mapping: MM_Test | urn:Test_test has syntax errors:

• Java Area import, Line 7: package firstpackage does not exist
  import firstpackage.*;
  ^
  Note: /usr/sap/PO7/J00/j2ee/cluster/server...

Hi Sathish,

Can you also post a screenshot of the imported Archive like I did in the thread?

Hi Mark

Please find the screenshot of Imported Archive

[markangelo_dihiansan · Accepted solution]

Hi Sathish,

Thank you, can you also include the path in the Imported Archive screenshot?

Regards,

Mark

Hi Mark,

Sorry I don't understand which path you are mentioning. I gave you the screen shot of Imported Archive with entire content and configurations in that window.

[markangelo_dihiansan · Accepted solution]

Hi Sathish,

The path is the other column in the display imported archive.

Mark

Hi Mark,

Sorry for that.

Path is empty.

Hi Sathish,

It does not look like the program you exported has a package or rather was created under the default package. Can you create a new package and place your class there and export it as a jar or zip file?

Regards,

Mark

Hi Mark,

This is the package.

I created in notepad and compile in command prompt. Then the java file and class files are zipped and included in Imported Archived.

I tried this 3 times, but still getting the same error.

Note : I have tested this package by creating a main class program and importing that package. It executed successfully in command prompt.

Hi Sathish,

This would be easier if you would be using an IDE such as Eclipse. You can include the classpath in javac by using the -cp option see this link for more information

Hope this helps,
