hi Jun wu,

As we are using the new server , after deploying a DC im getting yet another error like

WDRuntimeException : Failed to create delegate for component

for which i refer ed the below sdn url https://scn.sap.com/thread/1022824 in which they have specified about ProjectProperties.wdproperties having references to the added libraries etc , in my DC on cross checking it is missing some of the references so wanted complete detail of ProjectProperties.wdproperties , so that if possible i could edit and try to solve the error and im using NWDI .

can you build your dc locally?

[govardan_raj · Accepted solution]

yes  i have builded my DC locally , Dc is built successfully with out any errors.

[junwu · Accepted solution]

do you use dc build?

i think that file is auto generated based on what dependency you have specified. usually don't have to change it manually.

[former_member182372 · Accepted solution]

The problem is NOT:

com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to create delegate for component com.axisbank.custrpt.vccustreportcomp.VcCustReportComp. (Hint: Is the corresponding DC deployed correctly? Does the DC contain the component?)

The problem is:

java.lang.VerifyError: (class: com/xxxx/custrpt/vccustreportcomp/VcCustReportComp, method: getExportSummaryTableExcel signature: ()V) Incompatible argument to function

seems like the version of jar you are using to build (on NWDS) is not the same you are using to execute (runtime on the server). Are you usign external lib or used components?

[govardan_raj · Accepted solution]

HI maksim,

the external library dc was having the JXL jar file , I first removed external library dc , then created a new external library dc , then after deploying, the application started working with new external lib file, you are absolutly right it was problem with external library dc, that was not availble at run time .

[govardan_raj · Accepted solution]

but i have one doubt , like when we use external lib dc, during build time they dont give any errors but druing run time we face these kind of issues, why it happens and also it will be greatfull if you could explain about the external library usage dependencies , i.e Run Time , build time , deploy time etc.

[junwu · Accepted solution]

i don't think that is root cause.

without adding runtime dependency, it starts working?

getExportSummaryTableExcel is the method in component, nothing to with the jxl right?

from the log you provided, i think it is not external lib issue

it is dc build issue, if i am not wrong
