I am in the middle of building continuous integration using apache ant to execute the build.
Currently we are facing some weird ant warning. I already point the ant task to generate EJBGen to EJB file called DnAOperationEJB.java
Herewith the ant build file:
<ejbgen source="1.6" outputDir="${staging.dir}" descriptorDir="ejbModule\META-INF" forceGeneration="true"
ejbSuffix = "."
localSuffix = "Local"
localHomeSuffix = "LocalHome">
<fileset dir="ejbModule/sample/oss/dna/ejb">
<contains text="@Session"/>
<contains text="@LocalMethod"/>
</fileset>
</ejbgen>
After compiling, the result of the build was SUCCESSFUL as shown below
[ejbgen] Invoking EJBGen with the following command line:
[ejbgen] -d
[ejbgen] C:\Users\Jenkins Project\Sample\DnA_Ejb\staging
[ejbgen] -forceGeneration

[ejbgen] -ejbSuffix
[ejbgen] .

[ejbgen] Warning: No EJBGen file found!
BUILD SUCCESSFUL
Total time: 1 second
But the generated file from EJB Gen is not shown up in target folder. I think this is due to Ant cannot find the EJBGen file, as shown in the Warning: No EJBGen file found!
The source code of DnAOperationEJB.java as below:
/*

But i already put the EJB file to ant task.
Any ideas, help and/or comments?
After finding a best solution, there is SOLUTION for this kind of error.
First: verbose your EJBGEN function.
<ejbgen source="1.6" outputDir="${staging.dir}" descriptorDir="ejbModule\META-INF" forceGeneration="true"
verbose="true"
ejbSuffix = "."
localSuffix = "Local"
localHomeSuffix = "LocalHome">
<fileset dir="ejbModule/sample/oss/dna/ejb">
<contains text="@Session"/>
<contains text="@LocalMethod"/>
</fileset>
</ejbgen>
Then second, change the source from 1.6 to 1.5
In my case, there are another error thrown if i put 1.6 in the source. Exception in thread "main" com.bea.wls.ejbgen.EJBGenException: ejbName is a required attribute
answer this error here how to generate deployment descriptor using ejbGen for weblogic?
Then third, put the -lib parameter in your ant task. This is optional parameter if you not specify libraries that are not in your classpath. example:
ant build -lib ../lib -v > build.log
