java.lang.reflect.InvocationTargetException[JavaClassFunctionComponent]

[Manigandan Jegannathan]

Hello All,

I have a jar file which has two class files in it. One among the two java class invokes another one.

Its working and throws the output correctly from Eclipse as a java project.

When i use this as jar in TDI using JavaClassFC it throws below exception

[JavaClassFunctionComponent] CTGDIS810E handleException - cannot handle exception , functioncall

I tried adding the jar file TDI_HOME/jars/3rdparty/others. but it didnt work.

Could you share how you are instantiating the class(es) and calling methods?

Hello Eddie,

Now i have optimized my java project into single java class. This time i get different exception.

This is how i scripted javaclassFC, and the TDI_HOME/solution.props file has
com.ibm.di.loader.userjars=C:\jars


var usrEntry=system.newEntry();
var fc = system.getFunction("ibmdi.JavaClassFC");

fc.setParam("jarFile","C:\\jars\\C***anager.jar");
fc.setParam("javaClass","A****it");
fc.setParam("method","java.lang.String execute(java.lang.String p1, java.lang.String p2, java.lang.String p3, java.lang.String p4, java.lang.String p5)");
fc.initialize(null);


usrEntry.setAttribute("p1","s*************007'");
usrEntry.setAttribute("p2","8****3");
usrEntry.setAttribute("p3","17*****6");
usrEntry.setAttribute("p4","c***n");
usrEntry.setAttribute("p5","c*****in1");

task.logmsg("DEBUG",conn.value);
fc.perform(usrEntry);




Error i am getting,

[Script] CTGDIS809E handleException - cannot handle exception , script

Hello Eddie,

I figured it out. I was forced to change few java lines. java class FC throws exception with line number, so i went back modified the project. But now i have to figure it out why the below error is coming,

To be clear my eclipse project is doing certificate validation(using X509TrustManager), it works fine with eclipse. but TDI didn't....

Any help??

Hi rena,

You do not need to change your java class to make it run in TDI. Only thing you need to concern is how you use TDI Java FC and how you initiate it.

* verify whether TDI correctly invoking your jar
* if your jar program compiled and executed correctly then it must work in TDI. make sure you added the needed certificate if your program makes any ssl communication.

if it didn't help you, please share your TDI exception, we have TDI experts here they could help you. i found this forumn very helpfull.
