Extension: GWT - ERROR [GWT_DFE] - During Script Regeneration (LoadRunner 11.5)

Hi, I get error, provided below, in generation log.

 

!!!!!! Web Error: ERROR - DFE !!!!!!

Extension: GWT - ERROR [GWT_DFE] - java.lang.ClassCastException: com.hp.dfe.PathToFile cannot be cast to java.lang.Comparable

!!!!!! Error End !!!!!!

!!!!!! Web Error: ERROR - DFE !!!!!!

Extension: GWT - ERROR [GWT_DFE] - java.lang.UnsatisfiedLinkError: com.hp.dfe.CodeGenLoggerInterfaceBridge.nativeLog([BI)V

!!!!!! Error End !!!!!!

 

I configured .WAR file in chain configuration, added chain to Body and Header code generation.

Checked Headers in advanced settings for x-gwt-permutation

 

I also tried to add all .jar files .class files and .gwt.rpc as described in VuGen > Protocols > Web Protocols > How to use GWT-DFE, but still get this error.

 

gwt is structure remains as it was recorded, body requests remains unclear (I.e,   =7|0|18|http://xxxxxx//|4278/........)

 

It would be great if anyone could point to solution. Probably you already encountered this error and solved problem. Do not hesitate to share your experience 😉

Thanks in advance!!!

Hi Eugene,

 

What version of GWT is your AUT developed in?

And what version of Java?

 

I think I am familiar with a part of your problem,
if you open a support case I will be able to verify it.

 

Please feel free to contact me if you have any further questions.

 

Thanks,

Oded Keret

I am getting this same error on LR 11.5 when I am trying to replay a script that includes GWT.

 

Action.c(64): Error -27040: Data Format Extension: Extension: GWT - ERROR [GWT_DFE] - java.lang.ClassCastException: com.hp.dfe.PathToFile cannot be cast to java.lang.Comparable

 

   [MsgId: MERR-27040]
Action.c(64): Error -27040: Data Format Extension: Extension: GWT - ERROR [GWT_DFE] - com.hp.dfe.PathToFile cannot be cast to java.lang.Comparable

 

   [MsgId: MERR-27040]
Action.c(64): Error -27040: Data Format Extension: Extension: GWT - ERROR [GWT_DFE] - java.lang.ClassCastException: com.hp.dfe.PathToFile cannot be cast to java.lang.Comparable

 

   [MsgId: MERR-27040]
Action.c(64): Error -27040: Data Format Extension: Extension: GWT - ERROR [GWT_DFE] - failed to read as a response

 

Does this still require a hotfix to remedy? I am running on java 1.6 and GWT 2.4.0.

 

Thanks

So I have opened a ticket with no success so far. I got the latest update that was the hotfix mentioned above and still no change. I get the same error and am not able to test our GWT apps. Any input towards what might be causing this problem would be appreciated since it was advertised that GWT could now me used with LR. It was the reason why we upgraded.

This thread seems to have died without a resolution. Was there anything to solve these problems or do we assume it is still not working as advertised?
