I cannot seem to get past the BeanShellInterpreter whenever I try and use __FileToString built-in function in a BeanShell PreProcessor script. The FileContents variable does get populated, but the script fails and I cannot work with it. Here is the code and the error messages...
try {
Integer count=vars.get("SessionId").length()-5;
vars.put("vAuth", vars.get("v_username") + vars.get("SessionId").substring(count) + ":" );
log.info("Writing a info message");
${__FileToString(C:/tmp/DeltaConnectDemoTool_3_2_0S1_5515/bin/request.txt,,FileContents)};
log.info("Writing a second info message");
}
catch (Throwable ex ) {
log.error("Failed to do this or that", ex);
}
The Error is
2016/11/17 15:52:18 ERROR - jmeter.util.BeanShellInterpreter: Error invoking bsh method: eval In file: inline evaluation of: ``try { Integer count=vars.get("SessionId").length()-5; vars.put("vAuth", vars.get . . . '' Encountered ":" at line 5, column 8.

try putting the string path to file in double quotes, like:
${__FileToString("C:/tmp/DeltaConnectDemoTool_3_2_0S1_5515/bin/request.txt",,FileContents)};
That's why inlining functions or variables into the script body is not recommended. You have 2 alternative options:
Use the function in the "Parameters" section. If the functions returns some value you will be able to refer in later in the Beanshell code as Parameters or bsh.args[0] like:
Implement the function in the Beanshell code. In your case it can be FileUtils.readFileToString() function:
String FileContent = org.apache.commons.io.FileUtils.readFileToString(new File("request.txt"));
vars.put("FileContent", FileContent);

I use BeanShell code loading 100s of sql files in jmeter:
import org.apache.commons.io.FileUtils;
File folder = new File("D:\\sql99");
File[] sqlFiles = folder.listFiles();
for (int i = 0; i < sqlFiles.length; i++) {
File sqlFile = sqlFiles[i];
if (sqlFile.isFile()) {
vars.put("query_" + i,sqlFile.getName(),
FileUtils.readFileToString(sqlFiles[i]));
}
}
but get error info :
17:42:03,301 ERROR o.a.j.u.BeanShellInterpreter: Error invoking bsh method: eval Sourced file: inline evaluation of: ``import org.apache.commons.io.FileUtils; File folder = new File("D:\sql99"); Fi . . . '' : Error in method invocation: Method put( java.lang.String, java.lang.String, java.lang.String ) not found in class'org.apache.jmeter.threads.JMeterVariables'
I want to get each sql execute time in jmeter results tree. How to fix code?
Thanks!
You're trying to call JMeterVariables.put() function which accepts 2 Strings as the parameters passing 3 Strings
The correct syntax is vars.put("variable-name", "variable-value"); so you need to decide how to amend this line:
vars.put("query_" + i, sqlFile.getName(), FileUtils.readFileToString(sqlFiles[i]));
so it would contain only 2 parameters instead of 3.
Also since JMeter 3.1 it's recommended to use JSR223 Test Elements and Groovy language for scripting mainly for performance reasons so it might be a good option for switching (the same code will work in Groovy without changes assuming you fix the issue with vars.put() function call)
I am unable to print 'Output Variable' value of foreach Controller in Beanshell Pre/Post-processor in Jmeter.
log.info("inside hash"+ ${current_file} ); //current_file is the Output variable name defined in foreach controller and has the value of current file path.
File file=new File(${current_file});
byte[] content = FileUtils.readFileToByteArray(file);
Whenever I execute the tests, I get this error:
2021-12-15 19:58:25,208 ERROR o.a.j.u.BeanShellInterpreter: Error invoking bsh method: eval In file: inline evaluation of: ``import org.apache.commons.io.FileUtils; import org.apache.jmeter.services.FileSe . . . '' Encountered "( "inside hash" + C :" at line 4, column 9.
Can anyone help me fix this error?
Don't inline JMeter functions or variables in form of ${current_file}, use vars shorthand for JMeterVariables class instance instead
Something like:
String current_file = vars.get("current_file");
log.info("inside hash"+ current_file );
File file=new File(current_file);
Don't use Beanshell, since JMeter 3.1 it's recommended to use JSR223 Test Elements and Groovy language for scripting, there is a chance that your code will just start working after switching to Groovy or at least you will get more informative errors.
I want compare two values and pick which one is equal to second variable.
I have written code like below in BeanShellPostProcessor
HitID = vars.get("AddPrpc139");
b=139
if(HitID.equals(b))
{
log.info("......value=");
}else
{
log.info("......value=");
}
But i am getting below error
2018-11-27 14:48:53,504 ERROR o.a.j.u.BeanShellInterpreter: Error invoking bsh method: eval In file: inline evaluation of: `` HitID = vars.get("AddPrpc139"); b=139 if(HitID.equals(b)) { log.info("......val . . . '' Encountered "if" at line 4, column 1.

'' Encountered "if" at line 4, column 1.
Java/Beanshell expect ; at end of the line. Also b can be inlined
HitID = vars.get("AddPrpc139");
if("139".equals(HitIDb))
{
Also consider moving to JSR223 PostProcessor
You need to follow Java syntax rules, to wit you need to add a semicolon after b=139 line.
You should also surround this 139 with quotation marks otherwise JMeter will be comparing a String with an Integer and you will always get into else branch even if the values will be the same
Amended code:
HitID = vars.get("AddPrpc139");
b = "139";
if (HitID.equals(b)) {
log.info("Values are equal, expected: " + b + ", got: " + HitID);
} else {
log.info("Values are NOT equal, expected: " + b + ", got: " + HitID);
}'
Demo:
Be aware that according to JMeter Best Practices you should be using JSR223 PostProcessor with Groovy language starting from JMeter 3.1. Groovy is more modern language, it is compatible with latest Java features and it has much better performance. Check out Apache Groovy - Why and How You Should Use It article for more details.
The following code is in a BeanShell PostProcessor works fine when I run a test using Jmeter on GUI mode. If I run it from the command line I get the following exception:
015/09/10 18:25:13 ERROR - jmeter.util.BeanShellInterpreter: Error invoking bsh method: eval Sourced file: inline evaluation of: ``notFound="NOT_FOUND"; vars.put("AUDIT_CODE",notFound . . . '' : Typed variable declaration

Any idea why this could happen?
String notFound="NOT_FOUND";
vars.put("AUDIT_CODE",notFound);
String auditCode=vars.get("AUDIT_CODE");
if(auditCode.equals("NOT_FOUND")){
if (vars.get("AUDITS_RESULT_0")!=null){
String audit = vars.get("AUDITS_RESULT_0");
if(audit.contains("WAITING")){
String[] auditLineWithCode = audit.split("auditCode=");
String[] auditLineJustWithCode=auditLineWithCode[1].split(",");
vars.put("AUDIT_CODE",auditLineJustWithCode[0]);
log.info("AUDIT_CODE:"+vars.get("AUDIT_CODE"));
}
}
}
Change this line:
audit = vars.get("AUDITS_RESULT_0");
to
String audit = vars.get("AUDITS_RESULT_0");
I'm having an issue in JMeter wherein I receive this error
2014/08/14 14:13:26 ERROR - jmeter.util.BeanShellInterpreter: Error invoking bsh method: eval Sourced file: inline evaluation of: ``String RequestUrl = vars.get("RequestUrl"); String[] params = RequestUrl.split(" . . . '' : Typed variable declaration
2014/08/14 14:13:26 WARN - jmeter.extractor.BeanShellPostProcessor: Problem in BeanShell script org.apache.jorphan.util.JMeterException: Error invoking bsh method: eval Sourced file: inline evaluation of: ``String RequestUrl = vars.get("RequestUrl"); String[] params = RequestUrl.split(" . . . '' : Typed variable declaration
I have no clue whats wrong, and the code otherwise seems to be working. Can anyone give me some advice?
Here is the block of code in question:
String RequestUrl = vars.get("RequestUrl");
String[] params = RequestUrl.split("\\?");
String RequestTask = params[1].split("\\&")[1].split("=")[1];
System.out.println(RequestTask);
vars.put("RequestTask",RequestTask);
it should probably be mentioned that the code is in a post processor, which is paired with an Xpath extractor for "RequestUrl"
Edited to include entire error
I don't see your URL and what does XPath query return but in any case your URL parsing logic looks flaky as it strongly dependent on parameters order and presence and may bite you back in future in case of request URL change i.e. extra parameter or changed parameters order or something encoded, etc.
See below for reference:
import org.apache.http.NameValuePair;
import org.apache.http.client.utils.URLEncodedUtils;
import java.net.URI;
import java.util.List;
String url = vars.get("RequestUrl");
List params = URLEncodedUtils.parse(new URI(url), "UTF-8");
for (NameValuePair param : params) {
if (param.getName().equals("put your actual param name here")) {
vars.put("RequestTask", param.getValue());
}
}
Also it worth checking out How to use BeanShell: JMeter's favorite built-in component for troubleshooting tips. In general to localize error logging should be used like:
log.info("something");
log.error("something else");
So if you don't see message in the log than Beanshell wasn't able to execute the line and failed somewhere above.
Also Beanshell error messages aren't very informative, I use the following construction in my scripts:
try {
//script logic here
}
catch (Throwable ex) {
log.error("Failed to do this or that", ex);
}
So error stracktrace could be read in jmeter.log file.
Hope this helps.
Could you show the whole error?
Try adding one statement after the other to see which one is root cause.
I suppose you may be making hypothesis on results (array access) which may be cause of issue.
if you are coverting a VuGen recorded JMS script to JMeter, then you have to look for the lr functions copied which WILL throw this/similar error.
For eg: int orderlinecount = Integer.parseInt(lr.eval_string("strInt"));
You have to make sure your script is free of all lr - related functions in order for the jmeter to successfully executed your script.
