Hi, I have a question about accessing custom java classes inside SDI

public class ClassA { // this class is under package my.api.package

public String methodA()
{
String outString=””;
Try{
//some calculation;
}
Catch (exception)
{
// catch exceptions
}
return "outString";
}

I have made a Jar and placed it inside TDI_install/jar Directory, restarted the SDI and CE.
Now I am using a script connector to instantiate my class
Classobj = new my.api.package.ClassA();
Classobj.methodA();
But it gives me the error “java.lang.Exception: my not found”
Can anyone help me where I went wrong?
I also tried to use java class function component, and I was able to access the class but the drop down for selecting the method is empty, hence I cannot select the method.
Any Suggestions?
Thanks in Advance!

Placing your jar file under <TDI_INSTALLDIR>/jars should work. I always use a CustomJars folder in my Solution Directory and then have this line in solution.properties:

com.ibm.di.userjars=CustomJars

Under CustomJars I have sub-folders for the various libraries I am using. The TDI loader recursively scans for jars/zip files.

You are referencing the class correction: <package>.<class name> The 'my not found' is just a symptom of TDI not finding the jar, or that the jar is incorrect/corrupt. Btw. did you have a constructor for your class? I did not see one in the above snippet (of course, I am no Java expert, so bear with dumb observations :)

Thanks Eddie Hartman, it worked after placing the jars in a customjar sub directory inside <TDI_installDir>/jar directory :)

Great! I forgot to mention that when add/remove jars or import certs the you have to reboot the java vm - i.e. server and/or CE
