I'm making WebDriver Selenium scripts and trying to run them with JMeter.
I have an issue I don't understand. My code will crash at line 17 with this error in JMeter:
ERROR c.g.j.p.w.s.WebDriverSampler: Sourced file: inline evaluation of:
import org.openqa.selenium.*; import java.time.Duration; WDS.sampleResult.samp . . . '' : Error in method invocation: Method sendKeys( java.lang.String ) not found in class'org.openqa.selenium.remote.RemoteWebElement' : at Line: 17 : in file: inline evaluation of: ``import org.openqa.selenium.*; import java.time.Duration; WDS.sampleResult.samp . . . '' : .sendKeys ( "value" )
in inline evaluation of: ``import org.openqa.selenium.*; import java.time.Duration; WDS.sampleResult.samp . . . '' at line number 17
This is my code in WebDriver Sampler in JMeter:
code with .sendKeys method
What is the problem? Am I just blind?
I tried to import org.openqa.selenium.remote.RemoteWebElement directly to the script and I also tried to change syntax because I learned it was necessary to put an Array instead of a String behind .sendKeys method, but it didn't work for me.
I am using apache-jmeter-5.5 and Script Language in WebDriver Sampler is set to java.
You're just violating JMeter Best Practices, using Beanshell is not recommended since JMeter 3.1
The reason is that WebElement.sendKeys() function expects a CharSequence and you're trying to pass a String there and Beanshell interpreter doesn't like it.
Switch the language to groovy and the issue will go away. See Apache Groovy: What Is Groovy Used For? article for more information on Groovy scripting in JMeter
I'm calling PDFBox from Matlab to figure out how many pages there are in a PDF. Everything works great with Matlba 2016b and prior. I can import the library and load a PDF without a problem:
import org.apache.pdfbox.pdmodel.PDDocument;
pdfFile = PDDocument.load(filename);
When I run the same thing in 2017a, I get the following error:
No method 'load' with matching signature found for class
'org.apache.pdfbox.pdmodel.PDDocument'.
I can change the line after the import so that the function signature matches:
jFilename = java.lang.String(filename);
pdfFile = PDDocument.load(jFilename.getBytes());
However, this causes PDFBox to have problems when I call load:
Java exception occurred:
java.io.IOException: Error: End-of-File, expected line

at org.apache.pdfbox.pdmodel.PDDocument.load(PDDocument.java:1038)
This error seems to occur regardless of the PDF I'm trying to load. I'm getting the same exception with PDFBox 1.8.10 and 2.0.6.
I'm left with 2 questions:
Did Matlab 2017a change how it passes strings to Java? I didn't see anything in the release notes about this.
What could be causing the PDFBox error? Matlab is still on Java 1.7 in 2017a so I wouldn't think there should be any difference in how PDFBox works.
It seems like the method you are calling is from PDDocument version 1.8.11
In the latest version, PDDocument version 2.0.2 the method signature for accepting a file name no longer exists.
Change your code to the following, and it should work.
pdfFile = PDDocument.load(java.io.File(filename));
I have these java files:
LDF1File.java
LDFFile.java <-- super class
which generate these class files:
LDF1File.class -- there is no inner class
LDF1File$1.class <-- no idea where this comes from
LDFFile.class
In my python code, I can import LDF1File$1, but not LDF1File. I get:
>>> JClass('aero.blue.bdms.ldf.stream.LDF1File')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/eric/Software/anaconda3/envs/blue3/lib/python3.5/site-packages/JPype1-0.6.1-py3.5-linux-x86_64.egg/jpype/_jclass.py", line 55, in JClass
raise _RUNTIMEEXCEPTION.PYEXC("Class %s not found" % name)
jpype._jexception.RuntimeExceptionPyRaisable: java.lang.RuntimeException: Class aero.blue.bdms.ldf.stream.LDF1File not found
Here's the full code:
from jpype import *
startJVM(getDefaultJVMPath(), "-ea", '-Xms1024m', '-Xmx4096m', '-Djava.class.path=./jars/bdms-chunkjava-lib-1.0.9-SNAPSHOT.jar:./jars/bdms-ldfjava-lib-1.0.9-SNAPSHOT.jar')
LDF1File = JClass('aero.blue.bdms.ldf.stream.LDF1File')
shutdownJVM()
So i'm not sure why there is a class file with a dollar sign in it's name, and I'm not sure why JPype can't locate LDF1File. Just to rule some possible suggestions out, there is no dependency injection, no aspectj stuff, no spring, no guava. This is just plain java.
I had only included in my classpath the jar of the package i was working with and none of the dependencies. Having added all dependency jars to the classpath, it was able to load LDF1File.java
I am trying to write a script to help me track my Fitbit communities, but first I need to login to the site. Forgive me as I am a coding novice.
I am using Selenium in Python.
My code is as follows:

login_url = 'https://www.fitbit.com/login'
browser2.get(login_url)
browser2.implicitly_wait(5)
email1 = browser2.find_element_by_name('email')
password1 = browser2.find_element_by_name('password')
email1.click()
email1.clear()
WebDriverWait(browser2, 10)
email1.send_keys('notrealemail#mail.com')
WebDriverWait(browser2, 20)
password1.click()
password1.clear()

password1.send_keys('madeuppass')
WebDriverWait(browser2, 20)
form1 = browser2.find_element_by_class('common-btn common-btn-submit track-Auth-Login-ClickFitbit')
form1.submit()
When I run it I keep getting the following errors and the email/password boxes do not fill in. Here is the traceback:

I have been fiddling with this for hours and I can't get it to work. I see the element not visible error and it made me think I needed a delay, but then I tried to implement it (possibly poorly) and still I am getting errors. I also added the click and clear things as well as I saw those suggestions in other posts. I was able to login with RoboBrowser using the form submit, but some of the stuff I need to access later used java so it ended up being a dead end and now I've switched to Selenium and am stuck.
Try out this...
find_element_by_name is not able to find that element so you need to use xpath for it.

Do reply if you need more help.
I ran this code in Eclipse with java syntax it is working fine..
Happy Learning.. Enjoy :-)
You use WebDriverWait in a wrong way. Please refer to following line:
email = WebDriverWait(browser2, 10).until(EC.presence_of_element_located((By.ID,'email')))
This should allow to wait 10 seconds for required element before throwing an exception
You can also use try/except to catch TimeOut exception:
from selenium.common.exceptions import TimeoutException
try:
email = WebDriverWait(browser2, 10).until(EC.presence_of_element_located((By.ID,'email')))
except TimeoutException:
print('No Email input field found')
I have an python script which I need to run in my java application. I tried to execute it from jython but I have strange problem:
from sys import getdlopenflags
I get:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: cannot import name getdlopenflags
When I try to check contents of sys:
import sys
dir(sys)
the output is:
['JYTHON_DEV_JAR', 'JYTHON_JAR', 'PYTHON_CACHEDIR', 'PYTHON_CACHEDIR_SKIP', 'PYTHON_CONSOLE_ENCODING', '__delattr__', '__dict__', '__displayhook__', '__excepthook__', '__findattr_ex__', '__name__', '__new__', '__rawdir__', '__setattr__', '__stderr__', '__stdin__', '__stdout__', '_getframe', '_jy_interpreter', '_systemRestart', 'add_classdir', 'add_extdir', 'add_package', 'argv', 'builtin_module_names', 'builtins', 'byteorder', 'classDictInit', 'classLoader', 'cleanup', 'copyright', 'currentWorkingDir', 'defaultencoding', 'determinePlatform', 'displayhook', 'doInitialize', 'exc_clear', 'exc_info', 'excepthook', 'exec_prefix', 'executable', 'exit', 'filesystemencoding', 'getBaseProperties', 'getBuiltin', 'getBuiltins', 'getClassLoader', 'getCurrentWorkingDir', 'getDefaultBuiltins', 'getPath', 'getPathLazy', 'getPlatform', 'getWarnoptions', 'getdefaultencoding', 'getfilesystemencoding', 'getrecursionlimit', 'hexversion', 'initialize', 'isPackageCacheEnabled', 'last_traceback', 'last_type', 'last_value', 'maxint', 'maxunicode', 'meta_path', 'minint', 'modules', 'packageManager', 'path', 'path_hooks', 'path_importer_cache', 'platform', 'prefix', 'ps1', 'ps2', 'recursionlimit', 'registerCloser', 'registry', 'setBuiltins', 'setClassLoader', 'setCurrentWorkingDir', 'setPlatform', 'setWarnoptions', 'setprofile', 'setrecursionlimit', 'settrace', 'shadow', 'stderr', 'stdin', 'stdout', 'subversion', 'toString', 'unregisterCloser', 'version', 'version_info', 'warnoptions']
obviously getdlopenflags is missing. Is it possible to use this function in jython (I have the newest - 2.5.2) According to the documentation on the http://jython.org/docs/library/sys.html the sys.getdlopenflags is present.
Thanks for help
It says "Availability: Unix" in the documentation. The Jython docs seem to have copied that unchanged from the CPython docs. So this function is only available on a Unix installation. Possibly Jython doesn't have it at all - I don't know Java well enough, but since it's supposedly platform-independent, it can't support system-specific functions.
