Configuring the Studio

Setting studio options and preferences

Most studio configuration is done using the Studio Preferences Dialog (File > Preferences) within the studio. These preferences are saved in file userdata/properties/designer.properties. This file can be edited directly if required.

Change Java memory and/or Java parameters

Edit file userdata/bin/verjio_studio.vmoptions. Any parameters entered in this file override the distributed options file in installation_directory/Studio.

* -Xmx : Java maximum memory e.g. –Xmx2048m

* -Xms : Java initial memory e.g. –Xms768m

* -Dxx : Java –D parameters (multiple parameters are delimited by a space) e.g. –Dparm1=value1 –Dparm2=value2

Restart the studio.

Change Java version

The minimum Java level to run the Verj.io Studio is 1.8.0. A Java runtime environment is included with the distribution so this pre-requisite only applies if you want to override this and use your own Java version.

Edit file VerjioStudio.studio.inst at the root of the studio installation and change or set the VERJIO_STUDIO_JAVA environment variable. This file is located in parallel with the installation_directory e.g. if the installation directory is ../V5.6/VerjioStudio, then the file to edit is ../V5.6/VerjioStudio.studio.inst.

e.g.

VERJIO_STUDIO_JAVA=C:/Java_1.12.1

Restart the studio.

Change the userdata directory

Edit file VerjioStudio.studio.inst at the root of the studio installation and change the directory specified for the VERJIO_STUDIO_USERDATA environment variable. This file is located in parallel with the installation_directory e.g. if the installation directory is ../V5.6/VerjioStudio, then the file to edit is ../V5.6/VerjioStudio.studio.inst

Restart the studio. If the userdata directory is empty it will be populated by re-copying from installation_directory/Studio/initData.

Change Embedded Server options

See Configuring the Server.

Default colors and fonts

The default colors and fonts can be configured by editing file userdata/preferences/installation_preferences.xml. Click here for more details.

Layout configuration files

The docking configurations used by the studio are saved in a number of *.layout files in userdata/layout. These files cannot be edited, but if they are deleted the corresponding layouts will be reset to their defaults when the studio is restarted.

Add certificate to the Java trust store

The Java trust store is where you configure trusted certificates for communicating to external servers e.g. when importing a WSDL for a SOAP web service that uses a private certificate. If a file is found at userdata/security/truststore, its contents will be combined with the default Java trust store (jre/lib/security/cacerts). It is expected to use the JKS keystore format.

The following command uses the keytool utility program to add the certificate; it will also create the trust store file if it doesn’t already exist.

<path-to-java>/bin/keytool -import -file <certfile> -alias <alias-name> -storetype JKS -keystore <truststore location>

Where alias name needs to be unique for each certificate, but can be any name of your choice. This name does not affect the functioning of the certificate, but is required to subsequently remove the certificate.

Then answer any prompts from the keytool utility.

e.g.

cd to installation/jre/bin

keytool -import -file C:\cacerts\firstCA.cert -alias firstCA -storetype JKS -keystore userdata/security/truststore

See the Java keytool standard documentation for more information.

Log Files

The studio log files are located in the userdata/logs.

Modify FPL language syntax

Follow these instructions when you have modified the FPL language in some way, usually to add a custom function. This process will rebuild the ufsLanguage.jar which contains the compiled FPL language syntax. Note that rebuilding the ufsLanguage.jar is not strictly necessary to execute a custom function on the server. But it is required to get the FPL editor to recognize the new function as valid i.e. show the function in the Script Assistant and not generate a validation syntax error.

1. Modify the FPL.jj file in userdata/fpl and make any changes.

2. Recompile the ufsLanguage.jar by executing languageBuilder.bat or languageBuilder.sh in installation_directory/LanguageBuilder.

3. Restart the studio.

See also the documentation installation_directory/LanguageBuilder/readme.txt.

Note that to execute a new custom function on the server you will also need to add the function name and its corresponding Java class to the ebaseConf/userFunctions.xml on the server.
