Instant JChem can now be installed in three different ways:
Download Instant JChem installer. Before installing a new Instant JChem version, ensure to uninstall any previous version.
{primary} Starting with version 19.22.0, Instant JChem for Windows can now be installed using an MSI file. An MSI file is a type of installer package specifically for Windows, used to install a program, like Instant JChem, onto the system. This method allows for precise management of the installation process. Using the MSI file for installation is particularly useful for system administrators who need to install Instant JChem across a corporate network. It's important to note that the MSI package does not include Java, which must be obtained separately.
After installing, remember to check for and load any available updates by going to "Tools" and then selecting "Plugins".
To download the docker image for particular version navigate to download page.
Use the commands from the first section to login to Docker
It looks like this:
echo someapikeygeneratedforyou | \ docker login -u <yousername@chemaxon.com> --password-stdin hub.chemaxon.com
download the image you want with the following command:
docker pull hub.chemaxon.com/cxn-docker-release/ijc-jws-server:<version number>wherein, for example:
docker run -it --rm -p 8080:8080 jws-webappurlThe app will be accessible at http://localhost:8080/UrlWebApp/.
Add the zip file and ijp file to a local folder (example C:\Others\docker-jws-data\shared_projects) and bind it to the container on /usr/local/ijc_shared_data . The content of the folder will be copied to the right location inside the image.
Lets assume I have myproject.zip and myproject.ijp inside shared_projects.
docker run -it --rm -p 8080:8080 -v C:\Others\docker-jws-data\shared_projects:/usr/local/ijc_shared_data jws-webappurlThe project can be accessed by this url: http://localhost:8080/UrlWebApp/prj.jnlp?startJnlp
Of course, it might be helpful to also update the index.html file and add a reference to the new project. The updated index.html should also be placed in the same shared_projects folder.
docker run -it --rm -p 8080:8080 -e PROXY_WEB_SERVER="http://www.YourWeb.com:9080/urldemo/" jws-webappurlThe app will be accessible at http://localhost:8080/UrlWebApp/ but the links to projects and IJC will point to the chemaxon demo at http://www.YourWeb.com:9080/urldemo/.
docker run -it --rm -p 8888:8080 jws-webappurlThe app will be accessible at http://localhost:8888/UrlWebApp/.
you will need to provide a new index.html a new InstanJchem zip and a new info.properties. Put them all in a local folder, for example :\Others\docker-jws-data\shared_projects. The license file can also be put here.
-v C:\Others\docker-jws-data\shared_projects:/usr/local/ijc_shared_jwsFolders to bind:
Since version 2.2 Instant JChem can be launched using Java Web Start (JWS). This allows you to load it directly from a web-page rather than needing to install it first. The Java Web Start version should be fine for most users, but it is slightly less flexible, for instance should you wish to install your own or a third party's extension. For more information about the Java Web Start look here.
{warning} Automatic Update Center functionality was removed from Instant JChem after version 18.8.0 and is no longer supported.
When upgrading Instant JChem using any method, there may be substantial updates to the JChem version or changes in the way your project information is organized. Although we strive to ensure that these upgrades are seamless and straightforward, it's important to be cautious if your projects contain critical information that can't be easily recreated. We strongly recommend backing up your data before proceeding with the update. To do this, you can choose one or more of the following options:
Export your data to a file (e.g. SD file).
Take a copy of the complete project. Use the file manager (e.g. Windows Explorer) to copy (or create a zip archive) of the complete directory containing your project(s). Note: this will only back up data in local databases.
If you are using a MySQL or Oracle database you should ensure that you have a database backup before you update. Backing up the IJC project directory will not backup the data in these databases.
If you are having troubles installing or running IJC then the following notes might help.
IJC saves various settings and all updates it gets from the Update Center in a "userdir" which is usually found in:
Windows - c:\Users\<username>\AppData\Roaming\.instantjchem\<version number>
Mac OS X - $HOME/Library/Application Support/instantjchem/<version number>
Linux - $HOME/.instantjchem/<version number>
In case of Java Web Start installation, the <version number> changes to ws_<version number>
You can locate the exact directory by going to "Help" and then "About Instant JChem". If you encounter issues while installing or operating IJC, first ensure that no instances of IJC are running. Then, try renaming the directory mentioned and start IJC again. This action will create a new, clean user directory. Be aware that this will reset your current settings, and you'll need to reopen your projects in the case of an update. However, your data will not be lost.
Users, particularly those on Windows, should verify their default system encoding and font settings, as Instant JChem adheres to these defaults unless specified otherwise. If the default settings do not meet your requirements, it's important to adjust them.
For fonts, users should ensure that their chosen font supports the characters and symbols necessary for their work. This is especially crucial for displaying chemical structures and other specialized data correctly. Should you need to change default font settings in Instant JChem see documentation here.
We recommend using UTF-8 as the encoding format. To do so, you can either use command line and enter -Dfile.encoding=UTF-8 or navigate to etc/instantjchem.conf and add -J-Dfile.encoding=UTF-8 among default options already specified in the instantjchem.conf file.
