error message call when call one rfc which has changing parameter

[Former Member]

Hi all:

I have one rfc in my r/3 backend system.

YHR_TEST_FUNCTION_JSP

It has one parameter in changing : S_STRUCTION , which type is ZTEST_STRUCTION_TAB type.

I use NWDS to generate java proxy class for this bapi. The enterprise connector wizard helps me to generate the java proxy class, Yhr_Test_Function_Jsp_Input , Yhr_Test_Function_Jsp_Output .

I write the jsp code to use this java proxy class to call YHR_TEST_FUNCTION_JSP , my code looks like following:

-

---

Yhr_Test_Function_Jsp_Input input = new com.xinao.test.Yhr_Test_Function_Jsp_Input();

Ztest_StructionType ztype = new Ztest_StructionType();

ztype.setF_Parameter_1("ken2");

ztype.setF_Parameter_2("1");

ztype.setF_Parameter_3("1");

Ztest_StructionType_List ztypelist = new Ztest_StructionType_List();

ztypelist.addZtest_StructionType(ztype);

input.setS_Struction(ztypelist);

Test_PortType myproxy = new Test_PortType();

myproxy.messageSpecifier.setJcoClient(jcoclient);

Yhr_Test_Function_Jsp_Output output = myproxy.yhrTest_Function_Jsp(input);

-

---

After I run this code, it returns me the error message :

False parameter type during an Rfc call, error key: RFC_ERROR_SYSTEM_FAILURE

I cannot find out the reason of this error message

I check the old webdynpro code, I find that in webdynpro, if I import the same RFC, the java proxy input class will generate some method like " add " .

Why the pure java proxy class doesnot have the add method ? It only has setS_Struction

Is there anybody can help to check the problems ?
