Hi,

if you want to use some external jars in PI 7.1, try to execute your requirement in a java program with these jars included.import the zip in to ESR and then call this program from your UDF.Hope this works...

Use import functions as how we use to refer the other classes... import java.util.*

similarly use import for making use of your imported classes... (import com.yourpackagename...........)

Hi Rajesh,

As it is an External Jar file ,It will not be available in PI server. Then How can I use that in inport options.

Thanks.

Hi Amar,

check this blog ..

/people/alessandro.guarneri/blog/2006/01/26/throwing-smart-exceptions-in-xi-graphical-mapping

In this blog, a java program was written and compiled for throwing Runtime exceptions in message mapping. The class files generated are zipped and imported in to ESR. Then the required class is being called in the UDF.

You can create yours..in a similar fashion.

Hi Amar,

I mean after importing the external java class in the form of jar into the PI in imported sections...which contains the needed jar ...then refer it in import section of the UDF for the class needed....

It will work...

Hi All,

   I have also faced same problem, after struggling a lot, identified the reason is, external jar's class method should be static,after placing that , it is working fine.

Hi,

Please see that the .classpath and .project files are present inside the jar archive.

Also

for importing if your class name is Abc

in the package com.company then type

import com.company.Abc;

Hi Fariha,

Yes I have those 2 files. Totally I have four files in Imported Archives those are

.classpath
.project
.class
.java

and I am giving in my imports like

package.classname;

Still I am getting the Error.

And Suggest me onething ..

As Some people suggested like I can Directly import the external Jar file in Imported Archives and use it. Is it possible. I have tried that but getting same Exception.

Any Suggestions please.

Thanks.

How are you creating the jar file? I mean using which tool.

Of Course it was presumed that you are importing it in a Jar file

You can import this JAR into system as Imported archive.

In code you should create an object of this class:

myclass cl=new myclass();

Then you can access to methods and other elements of class as usual: cl.method(fieldvalue1,fieldvalue2,..,fieldvalueN);

[Former Member]

Hi All,

When I am creating the object of the class which is available in Imported Archives it is giving me an error like No Class Definition Found Exception

Please Help Me regarding this issue.

Thanks.

zip the esternal jar files you intend to use, import them under Imported Archives and you can refer to these jar files in the UDF

The jar files that you want to use should be present in the XI/ PI server....then while creating the UDF....after you enter the UDF name, parameters, on the page where you write your code, you mention the package name...under the import section (procedure for PI7.1)
