Currently trying to open the file gives this error:
C:\Users\....\....\apache-tomcat-8.0.45\logs>catalina.out
The process cannot access the file because it is being used by another process.
What I have done is to have application running in the webapps and start tomcat by using following command:
catalina.bat jpda start
And now I want to see the logs in windows. In Ubuntu, tail -f catalina.out can be used. But how to see tomcat logs in windows forcefully?
As stated in answers here, you can try more catalina.out or type catalina.out

I am trying to install flink on windows running into all sorts of problems . Please help.
Downloading the tar file from net, does not give me windows bat file options. Used the download links at https://flink.apache.org/downloads.html#apache-flink-1111. So i cannot run start-local.bat. Infact i dont even have start-local.sh . I ended up installing cygwin just so i can run start cluster bat
However running the start cluster bat is giving weird issues and exiting immediately.
$ ./start-cluster.sh
Starting cluster.

Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

I have been having issues getting my multibranch pipeline to perform git commands with an SSH key via the SSH Agent plugin on Windows.
I am able to successfully perform a git clone with the ssh from Git Bash on windows server that is running Jenkins.
In my pipeline log I am getting the following error when trying to use the sshagent plugin:
[ssh-agent] Looking for ssh-agent implementation... Could not find
ssh-agent: IOException: Cannot run program "ssh-agent": CreateProcess
error=2, The system cannot find the file specified Check if ssh-agent
is installed and in PATH [ssh-agent] FATAL: Could not find a suitable
ssh-agent provider
I have seen that installing Apache Tomcat Native libraries has helped some people, but the steps for doing so are not very descriptive.
Any help is appreciated. Thanks!
I've set up an App Engine project locally using Docker (on OSX), and have been running a server using the usual "gcloud preview app run app.yaml" command. From what I can tell, this keeps creating new images over and over again. After an hour or so of work I end up with something like 30 docker images, each taking 130MB.
Eventually I'm told I can no longer bind to localhost:8080. I tried killing all containers and images, but still cannot use localhost:8080 until I reboot.
Seems like I'm not using Docker/gcloud correctly. Anyone have an idea what I might be doing wrong? Is there another way I should be restarting App Engine instances other than hitting command C and running the "run" command again?
UPDATE: After looking closer, I noticed I'm getting this message when I run an app locally and a container is created: "http: Hijack is incompatible with use of CloseNotifier". I'm not familiar enough with Docker to understand what's going on here. All searches seem to point to Go, which I am not using.
UPDATE 2: Here is the trace:
Creating container...

There's an ongoing issue with Docker 1.6.x [reference] that prevents gcloud to work well with Managed VMs (as you seem to be using). Easiest workaround until it gets fixed is to downgrade Docker in your development machine to version 1.5.0, which is the latest version known to work.
For Ubuntu, you can do something like:
$ curl -sSL https://get.docker.com/ubuntu | sed 's/lxc-docker/lxc-docker-1.5.0/' | sudo sh
For other Linux distros, you might have to modify that sed pattern, though.
On the other hand, if you're using Boot2Docker under Mac OS X, follow these steps:
Fully uninstall your previous Boot2Docker/Docker setup; there is a nice guide here
Reinstall Boot2Docker/Docker following instructions here. IMPORTANT: You MUST stop right after completing "Install Boot2Docker" step and before "Start the Boot2Docker Application". Once you get there, open up a terminal and execute the following commands:
$ mkdir ~/.boot2docker
$ echo 'ISOURL="https://github.com/boot2docker/boot2docker/releases/download/v1.5.0/boot2docker.iso"' > ~/.boot2docker/profile
At this point, you can continue with "Start the Boot2Docker Application" section and finish the installation. You should now have a valid Docker launchpad with which to start Managed VMs. It'd be nice to double check that you have the right versions installed by issuing:
$ boot2docker ssh docker version | egrep "(Client|Server) version"
The output should look like:
Client version: 1.5.0
Server version: 1.5.0
Now you can try again your original command:
$ gcloud preview app run app.yaml
Try running:
$ ps uax | egrep "gcloud|appserver"
If you see anything running, kill it... you may even need to kill -9 it.
Trying to run my web2py app from the development server using GoogleAppEngineLauncher
Not sure if the on-line tutorials are out of date or I'm just missing something, but when I follow the link to download the GoogleAppEngine pythonSDK for OSX I get a dmg for the GoogleAppEngineLauncher.
I download and use that, which installs the proper executables, however after I setup my app.yaml file and run "dev_appserver.py myApp" I get this error:
fancy_urllib.InvalidCertificateException: Host appengine.google.com returned an invalid certificate (_ssl.c:503: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed):
I don't get the error if I try and launch the app from the launcher itself, however I can't launch the app because it says the directory already exists and I don't have write permissions. I even tried chmod 777 on the myApp directory.
Should I not be using the GoogleAppLauncher?
additionally I tried using the linux SDX and received the same "certificate" error. The error message directs me to a link mentioning that I need the "ssl" module, but that is included in python 2.7.2 which I am using.
The link also mentions: "appcfg uses SSL when connecting to the Admin Console by default, unless the --insecure flag is passed." But I cannot find that flag in the help menu.
Found this answer which solves the problem.
Basically:
rm google_appengine/lib/cacerts/cacerts.txt
From the SDK
I have GWT app, which is deployed on GAE (Java). I'm trying to download data from App Engine datastore using appcfg.py . I did all the setup according to http://ikaisays.com/2010/06/10/using-the-bulkloader-with-java-app-engine/ .
GAE Python SDK version is 1.4.3
Python version is 2.5.4
appcfg.py is on my PATH. When I run appcfg.py on the command-line, I get the "help" message. But the problem is that no matter which command I use, it always returns the help message. I have not been able to run any command using appcfg.py.
It doesn't give any specific error message no matter what arguments I give. My app is using Google Accounts authentication, but I don't think it even gets to the point of authentication.
I'm able to use the Java appcfg (for other actions like rollback) without any problem. But the Python version simply refuses to work for all commands.
I've tried different formats like:
appcfg.py create_bulkloader_config --url=http://myappid.appspot.com/remote_api --application=myappid --filename=config.yml
appcfg.py create_bulkloader_config --filename=bulkloader.yaml --url=http://myappid.appspot.com/remote_api
appcfg.py --filename=bulkloader.yaml --url=http://myappid.appspot.com/remote_api create_bulkloader_config
All give me the same help message:
Usage: appcfg.py [options]
Action must be one of:
create_bulkloader_config: Create a bulkloader.yaml from a running application.
cron_info: Display information about cron jobs.
download_app: Download a previously-uploaded app.
download_data: Download entities from datastore.
help: Print help for a specific action.
request_logs: Write request logs in Apache common log format.
rollback: Rollback an in-progress update.
set_default_version: Set the default (serving) version.
update: Create or update an app version.
update_cron: Update application cron definitions.
update_dos: Update application dos definitions.
update_indexes: Update application indexes.
update_queues: Update application task queue definitions.
upload_data: Upload data records to datastore.
vacuum_indexes: Delete unused indexes from application.
Use 'help <action>' for a detailed description.
Options:
-h, --help Show the help message and exit.
-q, --quiet Print errors only.
-v, --verbose Print info level logs.
--noisy Print all logs.
-s SERVER, --server=SERVER
...
...
...
Even when I try "appcfg.py help create_bulkloader_config" for a detailed description, it still shows me the same standard help.
I have also tried on the local development server using the url http://127.0.0.1:8888/remote_api but it still gives the same help message.
I'm totally clueless as to what the problem is. I'm new to GWT and GAE, and any help will be appreciated.
Thanks.
The following fix worked for me. It looks like appcfg.py doesn't like PYTHON27 and ALWAYS returns the help menu. I fixed it by executing it with PYTHON25 and hard coded all my file locations:
C:\Python25-archive\python "C:\Program Files (x86)\Google\google_appengine\appcfg.py" rollback C:\scripts\myapp
The right way is to change the environment variables on Windows 7:
Go to System Properties
Go to Advance System Settings
Click on Environment Variables
Append to Path variable the values C:\Python27\
Click Ok and restart your computer. (Yes, it is needed.)
Another way is to:
Open command Prompt
Locate your python.exe file. For example:
C:\Python27>_
Then, run a python command that looks like this.
python <appcfg_directory> download_app -A <your_app_id> -V <your_app_version> <output-dir>
Where <appcfg_directory> is equal to C:\Program Files\Google\google_appengine\appcfg.py. (Depending on your file location)
Don't forget to put quotes before and after <appcfg_directory>
