[tcljava-user] Help with reading data into a byte array in tclblend

[Ross, B. <Bil...@Ca...>]

I am new to Java but have doing TCL for many years.

I have one application that requires java.

I have gotten it all working but am now trying to add a new feature.

I get an object "cstat" back using tclbelnd.

According to the Javadoc I need to read it back into a byte array.

I then want to write it to a file using "$fos {write byte[]}
$dataBytes;"

I can't figure out the right syntax in tclblend to do this.

I can use a different Java command to get the size of the file which is
3188.

I tried creating a byte array of this size .

Any help would be appreciated.

 

Here is the line from the javadoc that shows the Java code that does the
data

 

 byte[] bytes = (byte[])cstat.getData();

 

 

Here is the relevant tclblend code I tried

        set fos [java::new java.io.FileOutputStream
"/home/server/output/filename"];

        set dataBytes [java::new {byte[]} 3188];

        set dataBytes [$cstat getData];

        $fos {write byte[]} $dataBytes;

        $fos close;

 

When I run my code I get

 

expected object of type byte[] but got "java0xc" (java.lang.Object)

    while executing

"$fos {write byte[]} $dataBytes"
