Cannot use WriteToFile function ([JavaPackage java.io.File] is not a function)

[Daniele Casanova]

Hi all.

I installed the new DE 12.0 with the embedded DB. The service and the DB work without problems.

I have a problem when i try to write a control file on the master server using an alert.

I created the alert with the option "run this JavaScript" anche the JS is:

 

"var tipoWrite = true;

function WriteToFile(fileName, strContent, tipoWrite) {

  var file = new java.io.File(fileName);

  var printResult = new java.lang.String();

  printResult = '';

  var pw = new java.io.PrintWriter(new java.io.BufferedWriter(new java.io.FileWriter(file, tipoWrite)));

  printResult = printResult + strContent+'\n';

  pw.print(printResult);

  pw.flush();

  pw.close();

}

var fileName='destinationPATH'+WOB._name+'.'+WOB._qualifier;

var applTstamp=APPL._SYEAR+'-'+APPL._SMM+'-'+APPL._SDD+' '+APPL._SHH+':'+APPL._SMN+'.'+APPL._SSS;

var fileContent = APPL._name+'|'+APPL._gen+'|'+WOB._name+'|'+WOB._qualifier+'|'+applTstamp;

WriteToFile(fileName, fileContent, tipoWrite);

 

var fileName='destinationPATH2'+WOB._name+'.'+WOB._qualifier;

var applTstamp=APPL._SYEAR+'-'+APPL._SMM+'-'+APPL._SDD+' '+APPL._SHH+':'+APPL._SMN+'.'+APPL._SSS;

var fileContent = APPL._name+'|'+APPL._gen+'|'+WOB._name+'|'+WOB._qualifier+'|'+applTstamp;

WriteToFile(fileName, fileContent, tipoWrite);"

 

the JS can't write the file and i read in the error log "TypeError: [JavaPackage java.io.File] is not a function, it is org.mozilla.javascript.NativeJavaPackage. (<cybscope>#5)".

The java version is 1.6.0_39.

 

what can i do fix this error?

 

Thank you all.

You can enable Java methods calls from JavaScript scripts in Admin perspective "Topology -> Configure Shared Parameters -> Internal -> Show Advanced Parameters" section;

 

Set the property "Allow Java calls in JavaScript" to true, and save the change.

 

See the docs; https://docops.ca.com/ca-wla-de/12-0/en/administrating/configuring/configuring-the-server-using-the-admin-topology#ConfiguringtheServerUsingtheAdminTopology-EnableJavaMethodCallsinJavaScriptScripts

 

For DE R12 Build 38, the Java version is 1.8.0_51

 

Thank you!

Thank you so much.

The alert now is working.
