Property exception component:'wsjLoader'

问题

In recent days I have been reading alot about modifying the HelloWorld demo file & adding new words in it of our own choice. But I am encountering a serious problem which I am unable to counter. I am listing down my steps & then the error program is giving me. Any help is much appreciated!

First I extracted the WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz jar file. And then I added some new words & their pronounciations in cmudict.0.6d file. After I saved it & compressed it back to jar file using a jar file maker.
The same step I repeated with HelloWorld jar file. After extracting I modified its hello.gram file by adding new words (the words which I inserted in dictionary as well as few words that were already there in dictionary e.g. John) Then I compressed it back using the same step & loaded both files on Eclipse. But both of them giving me a similar error. While the original demo files are working fine, these two files that I modified are not working anymore.

If I am replacing helloworld.jar file then I get this error:

and if I'm replacing WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz.jar

Although I know there is some problem with locating the files but I'm not getting how to fix it. Also can it be a reason that I might be compressing the jar files back in a wrong way? But keep that in mind that original demo files are working fine.

You made it wrong from the beginning, you should have used updated version sphinx4-5prealpha which is much easier to use. You should not repackage any sphinx4 jars. Here are the steps you need to make to create an application using sphinx4 and recognizing a custom grammar:

Setup a new java application in your IDE
Add sphinx4 dependency with jars or with maven/gradle.
Write grammar as requested and add it into application resources.
Write dictionary as requested and add it to application resources.
Copy SpeechRecognizer code from tutorial and modify path according to the location of the resources you created.

For more details, see sphinx4 tutorial
