xitix

Hello,

Please deploy my war file.

username: xitix

file: xitix_blog.war

Thanks

Thanks again, you're great!

 

My last changes into the code is not needed anymore.

Now the app deployment it works perfectly with your script modification.

 

On my side will be one more re-deployment in a week or two, for changing the method of avatar image uploading to mysql with the /tmp path.

 

I will prepare a how-to post for the users that want to build Java apps with Spring and Thymelef.

Dear,

Finally have solved the update for the avatar image uploading method. Please re-deploy the app.

Create a Java Spring Boot powered by Thymeleaf to be deployed on heliohost.org

It is mandatory to enter in the file application.properties of the folder src / main / resources , the following entries:

spring.datasource.url: jdbc:mysql://servername.heliohost.org/user_bookings?verifyServerCertificate=false&useSSL=false&requireSSL=false
spring.datasource.username = user_name
spring.datasource.password = password
spring.datasource.driverClassName = com.mysql.jdbc.Driver

spring.datasource.tomcat.max-active=2

server.contextPath=/user_demo
server.port=8080

spring.template.cache: false
spring.thymeleaf.check-template-location=true
spring.thymeleaf.prefix=classpath:/templates/
spring.thymeleaf.suffix=.html
#spring.thymeleaf.mode=LEGACYHTML5
spring.thymeleaf.encoding=UTF-8
spring.thymeleaf.content-type=text/html
spring.thymeleaf.cache=false

Pay attention in which PATH is the context_path that is used and in which java package is the class to use.

Any deployment in heliohost is done with an user_ in front of the WAR app. If you choose to have the server.contextPath with the correct deployment name, your app will not have any issue to run. On contrary, if your app have not such context from settings, you may need to change the context path from Thymeleaf if decide to use use Spring Security you may choose to disable the CSRF coockie path in order to use with Thymeleaf Server-relative URLs.

However, if you choose to bring from beginning an user_ in front of your name app, it will be more convenient for you.

Other important thing is: if you decide to use the heliohost database, you have to limit the max connection from your configuration, while spring.datasource.tomcat.max-active=50; pay attention, this is very important: spring.datasource.tomcat.max-active=2

As the licenses are payed per no# of connections, and the number impicit in Spring is about 50! You will not get access from heliohost, even when configure

from cpanel.

You have to configure carefully: Current Databases -> MySQL Users -> Add New User -> Add User To Database

Also, from RemoteMySQL you have to introduce your local IP (in case you need to test the app deployment on localhost, while connected to heliohost mysql database)

You may also like to check the mysql on heliohost with a simple php script.

To make it works, you also have to configure the proper rigths after upload the php file into public_html folder.

Do not forget to close the database connection at the end of the file, as you need to limit the number of coonections otherwise you may face some errors when test your remote connection: "com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: User user_name already has more than 'max_user_connections' active connections"

On the Java application template viewer part, chose to deploy with Thymeleaf Server-relative URLs.

You may check and double-check the app on your computer, before upload the WAR.

The best way is to deploy and test your app locally, and after you are shure that it works, you can upload to heliohost.

Please, be patient and pay respect on the communication with the admin.

Success & happy coding !

Thanks again, you're great!

My last changes into the code is not needed anymore.

Now the app deployment it works perfectly with your script modification.

On my side will be one more re-deployment in a week or two, for changing the method of avatar image uploading to mysql with the /tmp path.

I will prepare a how-to post for the users that want to build Java apps with Spring and Thymelef.

I'm positive no one has ever done most of what you're doing so if you can explain what you've done so far to make things work it would be beneficial to anyone who has the same issues in the future and finds this thread by searching.

Dear,

For shure I will explain in details on how to build such kind of project. I am already preparing this post. Finding a way to configure such app for heliohost it helps me learning Java with related frameworks. I am not clear if the "user_" agregation is made with Apache htaccess, or is done with Tomcat server xml configuration.

Today I have made little changes into code with an additional <cookie-config> and <path> to /user_app constraint, on the application config.

Let's test if such approach works.

Please re-deploy the app.

Thanks

Thanks for fast support!

The next problem I have to figure: server is responding with redirected context on login.

On the response header: "JSESSIONID=4A5A7470EC2659F3B2888C916166A146.jvm1;path=/xitix_xitix_blog;HttpOnly"

Still have to figure on how to solve this "user_" dynamic aggregation to the context path.

And I have other question: is there any option to upload some files into a Tomcat subfolder path?

Seems I cannot go to /home/xitix/public_html, while this folder are in a different path.

Thanks

Dear,

Nice to see that urlRewrite filter is pointing the context-app into a continuous loop.

have modified and shut down the filter.

Please re-deploy the app.

Thank you !

Some part of the code works, other don't.

deployed

So, still have to study & figure how-to solve on the Tymeleaf engine with MVC controller... to remain on the same path.

Have you read http://wiki.helionet.org/Java_Servlet#Edit_index.jsp_Source ?

 

Dear, have modified the code.

Let see if works now.

 

Have you read http://wiki.helionet.org/Java_Servlet#Edit_index.jsp_Source ?

Yes, I have read.

I do not use jsp with java servlet, but thymeleaf on spring framework.

However, there is no reference for "username_" into ../MyHelioServlet/ portion of the link.

Thanks,

Deployed. http://xitix.heliohost.org/xitix_blog/

Dear,

Still not working !

Now, heliohost.org is pointing all links to "~/xitix_xitix_blog/".

My project path is relative, and starts from "../xitix_blog/", according to previous discution on post #7.

I cannot setup my project to point on "relative paths like ../." because my intention is to have different services: each one is pointing to it's folder; the BOLG is the first web-app I would like to test on your site.

And even if point java web-app to the "relative path ../." your server setup will automatically redirect all links to "~/xitix_..." and the web-app will fail working. The automatically redirecting to "~/xitix_..." is annoying me

You may check, the blog-project runs perfectly fine on other friend space, that's temporarly hosting my java web-app:

http://blog.xitix.dynamic-dns.net:8080/xitix_blog/

http://blog.xitix.dynamic-dns.net:8080/blog/

Please advice on how to deploy my java web-app on heliohost.org,

Thanks,

P.S.

I believe might help if update the how-to documentation related to "`/user-path_" java deployment on heliohost.org

The most portable option is to not use absolute paths, but rather relative paths like ../. If you must use absolute paths the best way to do it is to determine your DOC_ROOT within your code in the same section where you definite global variables and then use the DOC_ROOT variable through the rest of your code. Using relative paths is easiest in my opinion.

 

Your username has to be appended to the beginning of your deployed app otherwise no one else would be able to use blog.war.

Dear,

Fortunately the paths are relative.

Ok, have refactored & changed the artifacts to help deploy on "~/xitix_blog".

Please:

1) stop and delete the old "blog"

2) redeploy the new web-app: "xitix_blog".

Dear,

Somehow it not works.

WAR is deployed on http://xitix.heliohost.org/blog/ while the files are pointing to http://xitix.heliohost.org/xitix_blog/

How to solve?

1) may I have all the files on "~/blog" folder and delete or modify the pointing to "/xitix_blog"?

2) have to refactor the initial eclipse project to install, re-deply and point to the "~/xitix_blog" ?

Thanks,
