Beanshell

[G.Ben]

Hello everyone,

Please, can anyone tell me what is wrong with this script ?

import org.ofbiz.base.location.FlexibleLocation;
import freemarker.ext.beans.BeansWrapper;
String scriptName = request.getParameter("scriptName");
if (scriptName == null || scriptName.length() == 0) {
return "success";
}
String lookInLocation = "component://learning/webapp/learning/WEB-INF/actions/entityaccess/";
URL location = FlexibleLocation.resolveLocation(lookInLocation + scriptName);
if (location == null) {
context.put("errorMsg", "Script name \"" + scriptName + "\" not found at " + lookInLocation);
return "success";
}
source(location);
bw = BeansWrapper.getDefaultInstance();
bw.setSimpleMapWrapper(true);
Object massaged;
if (data instanceof List) {
massaged = new ArrayList();
dataItr = data.iterator();
while (dataItr.hasNext()) {
record = (Map) dataItr.next();
massaged.add(bw.wrap(record));
}
}
else if (data instanceof Map) {
massaged = bw.wrap(data);
}
if (massaged != null) {
context.put("data", massaged);
}
return "success";



Thank you so much for your help,

Regards.

When trying to see the URL, I get the following error message :


org.ofbiz.widget.screen.ScreenRenderException: Error rendering screen [component://learning/widget/learning/LearningScreens.xml#ProcessEntityAccessBSF]: java.lang.IllegalArgumentException: Error running script at location [component://learning/webapp/learning/WEB-INF/actions/entityaccess/processEntityAccessBSF.bsh]: javax.script.ScriptException: Sourced file: eval stream : Attempt to resolve method: length() on undefined variable or class name: scriptName : at Line: 4 : in file: eval stream : scriptName .length ( )

Thanks  for replying

The error message tells you the problem exactly:

Attempt to resolve method: length() on undefined variable or class name: scriptName : at Line: 4 : in file: eval stream : scriptName .length ( )

This means, that you cannot call this method (length()) on a "null" value.

In Groovy, a null or empty string evaluates to a boolean false value, so you can just write:


if (scriptName) {
return "success";
}

Sorry, I meant

if (!scriptName) {
return "success";
}

cause you wanted the success return when it is null or empty.

Thank you so much Robert G.

I couldn't understand the error message.

Thank you again.

Helloo, I found another Error,

Actually I'm trying to run a beanshell script that allows me to run another script to access entities (according to a tutorial), I did all what they said however when trying to visualize the URL I get the following error : (The URL first show a field when I enter the script that I would run, trying to click on submit I get an error)

"org.ofbiz.webapp.control.RequestHandlerException: Unknown request [processEntityAccessBSF]; this request does not exist or cannot be called directly."



here are the files that are involved in this operation :

Hi Ben
It is a mistake in 'p', use it.

<request-map uri="processEntityAccessBSF">
     <response name="success" type="view" value="ProcessEntityAccessBSF"/>
</request-map>

Regard
