Hi ,  
I am trying to call a java file using logstash in output using pipe .

> input  
> {  
> stdin {}  
> }

> filter  
> {  
> ruby  
> {  
> code =\> "  
> event['id']=File.open('/elkt/software/bkup/logstash-1.5.4/bin/wid.id', &:readline)  
> "  
> add\_field =\> ["id", "%{id}"]

> ```
> }
> 
> ```
> 
> }

> output  
> {  
> pipe {  
> command =\> "java HelloWorld %{id}"  
> }  
> stdout {codec =\> rubydebug}  
> }

passing the parameters it is showing this error saying that

> Error writing to pipe, closing pipe. {:command=\>"java HelloWorld '12321321\n", :pipe=\>#\<PipeWrapper:0x4bb4e0e2 @pipe=#\<IO:fd 422\>, @active=true\>, :level=\>:error}

id was :-12321321

This isn't necessary.

> command =\> "java HelloWorld %{id}"

This assumes that HelloWorld.class is in the current directory (or otherwise in the classpath) when the JVM is started. I wouldn't assume anything about the current directory. Try changing the command to `cd /some/path && java HelloWorld %{id}`.
