I need to create a server-side app that saving information to a mongoDB ,
I'm working with java-eclipse-IDE and i have some problems with that .
First ,
I download the mongo-2.7.2.jar and add it to the path ( project ->properties-> java build path -> add jar -> (adding the mongo-2.7.2.jar file ) .
When I press "Run" without writing any other line except the empty - class & main function
The console writing me that :
CLI (1) [java application] path date
Usage : [--bucket bucketname] action
where action is one of:
list : lists all files in the store
put filename : puts the file filename into the store
get filename1 filename2 : gets filename1 from store and sends to filename2
md5 filename : does an md5 hash on a file in the db (for testing)
I tried to put a system.out.print("indications") in the main function but the console showing me the same output ...
onother interesting fact is when i'm wrting a code using a mongo DB the compiler accepted the code and not throwing errors ( seems he accepted the mongo-2.7.2.jar ).
second ,
I thoght maby i need to install a mongoDB plugin to eclipse , should i?
third ,
I saw that maven is integrated a mongoDB service , is it right that i should download maven to eclipse for handle mongoDB?
I need help soon as possible ....
Thanks.
Sounds like its trying to do something with GridFS but is missing a bucket name... are you using GridFS?

Situation
First of all I must mention that I'm using Solr 8.1.1 and am running the default "solr -e cloud" to do some testing. This is running on a Windows Azure VM. I'm trying to create a PowerShell script that will do some setup on the SolrCloud. The first step in this is uploading a custom Configset. I was using https://lucene.apache.org/solr/guide/8_1/configsets-api.html as guide and the PowerShell command if you take away all the parameters and such boils down to the following:
Invoke-WebRequest -Uri "http://localhost:8983/solr/admin/configs?action=UPLOAD&name=MyConfig" -Method Post -ContentType "application/octet-stream" -InFile "config.zip"
EDIT: For clarity the contents of the ZIP is as follows: https://imgur.com/a/OHR1bf1
Problem
When I run the above command however I'm met with the following error:
Invoke-WebRequest : { "responseHeader":{ "status":500, "QTime":11}, "error":{ "msg":"KeeperErrorCode = NoNode for /configs/MyConfig/lang/contractions_ca.txt", "trace":"org.apache.zookeeper.KeeperException$NoNodeException:

Observations
When I first "failed" I had created a zip file from my config which contained an additional top level folder (ea instead of MyConfig/solrconfig.xml etc my ZIP was MyConfig/MyConfig/solrconfig.xml) and when I used this the command was run successful but the second command (creating a collection) would fail because it could not find solrconfig.xml. This tells me that the ZIP is correctly present in the request and Solr does seem capable of processing it but once I correct it to an actual configset it massively fails?
EDIT: I was asked about this and whether using "conf" in the zip would work. As I mentioned here this results in a successful upload (https://imgur.com/a/JHLZ8td) however as you can see it does not match the other config sets and when you try to create a collection with this set you will get Error CREATEing SolrCore 'Test_shard1_replica_n1': Unable to create core [Test_shard1_replica_n1] Caused by: Can't find resource 'solrconfig.xml' in classpath or '/configs/Sitecore', cwd=C:\solr-8.1.1\server
Question(s)
What am I doing wrong? Is this a bug?
Going back through some work I did on SolrCloud a while ago, I am reminded of one annoying issue I hit:
I got odd issues uploading the schema config zip files if I had created that zip using "Send to Compressed Folder" in the Windows UI, or via Compress-Archive in PowerShell. I found that compressing the data with 7Zip did work, however.
I suspect there's something incompatible between the Windows zip code (which I think is quite old, and something they licensed ages ago?) and how Solr/ZooKeeper deals with extracting the files again?
I just ran into the same issue without using Windows zip code. I was trying to upload a configset to Solr 7.7.3 from a conf directory containing a "lang" subdirectory with a bunch of files. I got the NoNode error for /configs/_myconfigsetname_/lang/stopwords_eu.txt. The configset was being zipped on the fly through a recursive directory walk in Java, sending each filename to the Zip file using Java's ZipOutputStream. The resulting zipped bytes were then sent to Solr/Zookeeper.
This code worked fine for conf directories without subdirectories. It turned out that when there is a subdirectory, it was necessary to create a ZipEntry for the directory (e.g. lang/) before adding files to the Zip stream such as lang/stopwords_eu.txt.
I tried to train the tesseract 4.1 using OCRD project but after training completed I copied the lang.traineddata but getting above error.
The tesseractWiki page is very confusing to understand asking to use combine_lang_model after making lstmf file. So Actually I have the lstmf file. I created these file by using tif/box pair.
Please help me for further step.

Suppose your training folder like this:
OCRD/makefile
OCRD/data/foo-ground-truth.
You could try as following steps:
Find the WORDLIST_FILE/NUMBERS_FILE/PUNC_FILE in the makefile, and change them to:
WORDLIST_FILE := data/$(MODEL_NAME).wordlist
NUMBERS_FILE := data/$(MODEL_NAME).numbers
PUNC_FILE := data/$(MODEL_NAME).punc
Suppose your base traineddata is eng.traineddata.
2.1 Download the .wordlist/.numbers/.punc files from the langdata_lstm.
2.2 Place them in OCRD/data
2.3 if the MODEL_NAME = foo, rename them as: foo.wordlist, foo.numbers, foo.punc
if you don't have the base traineddata, you could try this too. But if your base traineddata is afr, you should download the files from langdata_lstm/afr.
make training again
The cause of this error：
In OCRD, the default path of the above three files is $ (OUTPUT_DIR) = data / $ (MODEL_NAME), and all files in this path are automatically generated during the training process.
If the variable START_MODEL is not assigned, the makefile will not generate any related files under this path;
If the variable START_MODEL has been assigned, the foo.lstm-number-dawg、foo.lstm-punc-dawg、foo.lstm-word-dawg and so on will be produced in data / $ (MODEL_NAME). But they are not the right one. So there may be a bug in OCRD.
I've been struggling to deploy my shiny app using the tesseractpackage. It seems that it can't 'reach' the downloaded languages. In my case: English and Dutch.
When setting up the language, the resulting object should 'point' to a path. That's the part where shiny can't open the connection.
Any help would be much appriciated!
Kind regards, R
Below I've copied the error message and the relevant code.
This is the error message I get after deployment:
Warning in file(con, "wb") :
cannot open file '/usr/share/tesseract-ocr/tessdata/nld.traineddata': Permission denied
Error in value[3L] : cannot open the connection
Calls: local ... tryCatch -> tryCatchList -> tryCatchOne ->
Execution halted
This is my code
#loading software requirement
library(tesseract)
#download language (dutch)
tesseract_download('nld')
tesseract_download('eng')
#set language parameters for later use.
dutch <- tesseract('nld')
english <- tesseract('eng')
I've managed to get it working myself. The key was taking the following steps:
Creating a subdirectory (of folder) which is called 'tessdata'. This subdirecty is the directory you can download the languages in and 'set' the languages.
When deploying your app, you have to deploy this tessdata-subdirectory as well. So in the deployement prompt, you 'tick' the boxes of this folder as well.
Then make sure the tesseract engine points at the following path:
Screenshot of how to upload the tessdata-folder along with the app
enter image description here
Please see the code below
#loading software requirementlibrary(tesseract)
#Make sure the tesseract package is 'pointing' at the right 'parent directory'
#which is in this case the path your shiny app is working from.
#That's why you need the dot ("."). Which is in essence the workdir.
Sys.setenv(TESSDAT_PREFIX = ".")
#so combining the workdir and the pre-installed folder 'tessdata'
path <- paste0(getwd(), '/tessdata')
#use this path for downloading
#download languages (dutch and english)
tesseract_download('nld', datapath = path)
tesseract_download('eng', datapath = path)
#set language parameters for later use, using the same path
dutch <- tesseract('nld', datapath = path)
english <- tesseract('eng', datapath = path)
I am new to cucumber and I am automating a scenario. Initially I kept my features files in the path C:\Users\test\eclipse-workspace\Automation\src\test\resources\featureFile. Then I moved the feature files to a different path (C:\Users\test\eclipse-workspace\Automation\src\test\com\test]automation\features). I have updated the same in CucumberOptions as shown below.
#CucumberOptions(features = {
"src/test/java/com/test/automation/features/CO_Self_Service_Home_Page_Personalizations.feature" }, glue = {
"src/test/java/com/oracle/peoplesoft/HCM/StepDefinitions" })
But when I try to run the feature, I am getting the below exception stating the feature file is not found. Here the path shown in the exception is the old path. I am not sure from where it is fetched as I have updated the new path in Cucumber options. Can you please help me understand the cause of this issue.
Exception in thread "main" java.lang.IllegalArgumentException: Not a

There are a couple of points you need to take care as follows :
As per Best Practices cerate the directory features which will contain the featurefile(s) strictly through your IDE only (not through other softwares Notepad or Textpad or SubLime3) as per the image below (New -> File) :
Create the featurefile i.e. CO_Self_Service_Home_Page_Personalizations.feature within features directory strictly through your IDE only.
Keep your Project Structure simple by placing the directory containing the featurefile(s) just under Project Workspace. For Featurefiles Cucumber works with directory names. So create the features directory just under your project space Automation (same hierarchy as src). So the location of the Self_Service_Home_Page_Personalizations.feature will be :
C:\Users\test\eclipse-workspace\Automation\features\Self_Service_Home_Page_Personalizations.feature
Again, as in your Class file containing #CucumberOptions you have mentioned glue = {"StepDefinitions" } ensure that the Class file containing #CucumberOptions must be in the similar hierarchy as the figure below :
So your CucumberOptions will be as follows :
#CucumberOptions(features = {"features" }, glue = {"StepDefinitions" })
Execute your Test
Note : Do not move/copy feature file(s)/directory(ies). Delete the unwanted and create a new one through your IDE only.
I did set up the hadoop Ubuntu OS, followed all the necessary steps,
1.created the hdfs file system
2.Moved the text files to input directory
3.having privilege to access all the directories.
but when run the simple word count example, i got
Exception in thread "main" org.apache.hadoop.mapreduce.lib.input.InvalidInputException: Input path does not exist: file:/user/root/input
at org.apache.hadoop.mapreduce.lib.input.FileInputFormat.listStatus(FileInputFormat.java:224)
but, input path is valid and even can able view the files in that path from eclipse itself, so plz assist were i am wrong.
attached the screenshot for the reference
Add the following 2 lines in your code :
config.addResource(new Path("/HADOOP_HOME/conf/core-site.xml"));
config.addResource(new Path("/HADOOP_HOME/conf/hdfs-site.xml"));
Your client is looking into the local FS.
For hadoop-2.2.0 on windows 7, I added the below lines and it solved the issue (NOTE: My Hadoop Home is: C:\MyWork\MyProjects\Hadoop\hadoop-2.2.0)
Configuration conf = new Configuration();
conf.addResource(new Path("C:\MyWork\MyProjects\Hadoop\hadoop-2.2.0\etc\hadoop\core-site.xml"));
conf.addResource(new Path("C:\MyWork\MyProjects\Hadoop\hadoop-2.2.0\etc\hadoop\hdfs-site.xml"));
