| | 145 | === GNU Debian ===#GNUDebian |
| | 146 | Our own Ubuntu packages, [#Ubuntu above], work on Debian and we recommend to use them. Depending on the setup of `sudo`, some instruction will not work as "normal" user but only as `root`. |
| | 147 | |
| | 148 | The tested version of [https://packages.debian.org/stable/josm JOSM] is available under **''main''** in section **''utils''**, but the version is usually quite old. \\ |
| | 149 | Please, use the [https://backports.debian.org backports repository] to get a more up-to-date version, see [https://backports.debian.org/Instructions Instructions]. This version might still be older than our own packages. |
| | 150 | |
| | 151 | Since Debian 11 (bullseye) the [https://packages.debian.org/stable/josm-installer josm-installer] is available under **''main''** in section **''utils''**. It downloads the current .jar file from this site and updates it if necessary. |
| | 152 | |
| | 153 | === openSUSE ===#Opensuse |
| | 154 | The tested version of JOSM is available in the Application:Geo repository.[=#openSUSE] |
| | 155 | |
| | 156 | First add as root user in yast or with zypper the repository (for Tumbleweed replace **$releasever** with **openSUSE_Tumbleweed**): |
| | 157 | {{{#!sh |
| | 158 | zypper ar -f 'https://download.opensuse.org/repositories/Application:/Geo/$releasever' Application:Geo |
| | 159 | }}} |
| | 160 | |
| | 161 | Then simply install ''josm'' and ''josm-fonts'' package. |
| | 162 | |
| | 163 | === Arch Linux ===#ArchLinux |
| | 164 | |
| | 165 | The official repository contains the `josm` [https://archlinux.org/packages/extra/any/josm/ package], which can be installed via `pacman -S josm`. |
| | 166 | |
| | 167 | The Arch user repository (AUR) additionally contains the `josm-latest` [https://aur.archlinux.org/packages/josm-latest package] with the latest version of JOSM. |
| | 168 | Use your AUR helper to install this package. |
| | 169 | |
| | 170 | Both packages are third-party-packages and not maintained by the JOSM-team. |
| | 171 | |
| | 172 | == Troubleshooting == |
| | 173 | === Java ===#Java |
| | 174 | When you double-click on a jar file and nothing happens in most cases this means Java isn't installed. |
| | 175 | |
| | 176 | JOSM now recommends [https://www.azul.com/downloads/?version=java-21-lts&package=jdk-fx#zulu Azul] or [https://bell-sw.com/pages/downloads/?package=jre-full#mn Bellsoft Liberica] JDK's. Generally speaking, the current Java LTS should be preferred (at time of writing, that would be Java 25), but Java 11 will work. See the [source:/trunk/README README] for current recommendations. But first give the Java already distributed with the operating system a try, [https://en.wikipedia.org/wiki/OpenJDK for example]. |
| | 177 | |
| | 178 | |
| | 179 | When choosing a download keep in mind: |
| | 180 | * A Java Plug-in for web browsers is **not** needed to run JOSM. Therefore results from pages like www.java.com/en/download/installed8.jsp are not relevant. |
| | 181 | * A Java variant with 64 bit is recommended for JOSM. The operating systems architecture is important for deciding between 32 bit Java or 64 bit Java. Because JOSM is **not** affected by the web browsers architecture most recommendations on this page www.java.com/en/download/faq/java_win64bit.xml are not relevant. |
| | 182 | * Avoid pages like www.java.com/en/download which intent to place Java Plug-ins in web browsers. And this is **not** important for JOSM. |
| | 183 | |
| | 184 | For further information visit the [wikitr:/InstallNotes Installation Notes] and [https://www.java.com/en/download/help/troubleshoot_java.xml troubleshooting] pages. |
| | 185 | ''Java'' in this section means a JRE (Java Runtime Engine) which provides a JVM (Java Virtual Machine) to run JOSM, a Java program that is developed using JDK (Java Development Kit) and sometimes launched with the JNLP (Java Network Launch Protocol aka Web Start and successor of Java Plug-ins). |
| | 186 | |
| | 187 | ==== Testing Java ====#JavaTest |
| | 188 | [=#Troubleshootingjarfile] Checks if Java is installed and why JOSM does not start (example mainly for MS Windows). |
| | 189 | 1. Download [/josm-tested.jar josm-tested.jar] to your desktop. |
| | 190 | 1. Open a Command Prompt aka Terminal |
| | 191 | 1. Type `cd %homepath%`⏎ and type `cd Desktop`⏎ |
| | 192 | 1. Type `java -version `⏎ Three lines with the version data should appear. If you see something else then Java is not properly installed. |
| | 193 | 1. Type `java -jar josm-tested.jar`⏎. Now JOSM should run, started from the [wikitr:/Help/CommandLineOptions Command Line]. |
| | 194 | 1. Quit JOSM. |
| | 195 | 1. Type `josm-tested.jar`⏎. If JOSM starts again, the Windows Explorer is ready for double clicks on jar files. |
| | 196 | |
| | 197 | |
| | 198 | === Web Start ===#Webstart |
| | 199 | [=#Troubleshootingjhlplink] |
| | 200 | You need to install [https://openwebstart.com/ OpenWebStart] first. It will download and run Java by itself. Please use the 64 bit (`x64`) version of OpenWebStart if you are on Microsoft Windows. The transition from Oracle WebStart to OpenWebStart is still in progress, so in case of issue please create a [/newticket new ticket] or post a comment to #17858. |
| | 201 | |
| | 202 | You may need to update the default application for opening JNLP files if you previously used Oracle WebStart. See [https://openwebstart.com/docs/OWSGuide.html#_jnlp_file_association jnlp file association] for instructions on setting OpenWebStart as the default program for jnlp files. |
| | 203 | |
| | 204 | ==== Testing Web Start ====#Webstarttest |
| | 205 | 1. Download [/download/josm.jnlp josm.jnlp] to your desktop. |
| | 206 | 1. Open a Terminal and move to the Desktop as above |
| | 207 | 1. Type `javaws josm.jnlp`⏎. This should initially download JOSM, show a security dialog and then launch JOSM. |
| | 208 | 1. If that fails, then type `javaws -verbose josm.jnlp`⏎. This should first show a dialog with information about the JVM and then launch JOSM. |

| | 211 | === Virtual Machine ===#Troubleshootingjvm |
| | 212 | ==== Out of memory ==== |
| | 213 | Nowadays manually controlling Java's memory is seldom needed because available RAM on computers has grown. |
| | 214 | Wrongly chosen values can decrease JOSM performance. |
| | 215 | |
| | 216 | For some tasks, JOSM has a large appetite for memory. On the one hand, it may be necessary to configure a memory size that supports more plugins and features. On the other hand can slow machines be stabilized by restricting Java's memory use. |
| | 217 | If needed, use the [wikitr:/Help/CommandLineOptions command line] to set the [https://docs.oracle.com/en/java/javase/11/tools/java.html#GUID-3B1CE181-CD30-4178-9602-230B800D4FAE__BABHDABI Java Option] -Xmx…m, for example `-Xmx512m` or `-Xmx1536m`. In Debian/Ubuntu you can edit the file `/etc/default/josm` respectively `/etc/default/josm-latest`. \\ |
| | 218 | Formerly older java programs accepted `-Xmx=512m` or even `-Xmx 512m`. Now those malformed arguments throw error messages. |
| | 219 | |
| | 220 | ==== VM selection ====#VMselectiononWindowsx64 |
| | 221 | On current versions of MS Windows by default Java is installed mainly in the `C:\Program Files\Java\` directory. Additional parts are placed in `C:\Program Files\Oracle\Java\`. There is a `.\javapath\` directory as target for the PATH environment variable. It is the home for the three virtual files `java.exe`, `javaw.exe` and `javaws.exe`. This files are symbolic links form the current Java installations. |
| | 222 | |
| | 223 | On older versions of 64 bit Windows sometimes the 32 bit mode JRE was additionally installed. Also some browsers brought their own JVM with limited capabilities. In those cases a Web Start from the browser would not use your Java installation but that from the browser. |
| | 224 | |
| | 225 | Check that there's no other javawebstart in `\Windows\SysWow64`. The Java control panel will not detect it and you can safely delete it. Perform cleanup and only keep the latest versions of each JRE (One or the 32-bit mode, another one for the 64-bit mode). |
| | 226 | |
| | 227 | For shortcuts created on the desktop for JNLP and running the Javawebstart launcher , make sure to pass VM parameters prefixed with -J and no intermediate space before the VM option. If you have installed both the 32-bit and 64-bit version, you should pass the option "`-d64`" if you want to select the preferred 64-bit VM. Note that some Oracle documentation pages indicate the option "-D64" with the incorrect capitalization!) |

| 139 | | |
| 140 | | JOSM is tested and developed with Oracle JVM, therefore we recommend to get Java from their [https://www.java.com/en/download/manual.jsp manual download] page. |
| 141 | | Mind your systems architecture (32 or 64 bit) when [https://www.java.com/en/download/faq/java_win64bit.xml choosing] the installation. Java 64 bit is recommended for JOSM. |
| 142 | | Please avoid the page java.com/en/download because its automatic detection may fool you. |

If you have installed both the 32-bit and 64-bit version, you should pass the option "{{{-d64}}}" if you want to select the preferred 64-bit VM. Note that some Oracle documentation pages indicate the option "-D64" with the incorrect capitalization!) |

| 188 | | Example of an edited commandline for the shortcut created on the windows desktop after running JOSM just once from the JNMP and exiting: |
| 189 | | {{{ |
| 190 | | #!sh |
| 191 | | <path>javaws.exe -J-d64 -J-Xmx2048m localfile |

| | 256 | For giving [wikitr:/Help/CommandLineOptions#Javaoptions Java options] to the Java VM, JOSM.exe uses the configuration file `JOSM.cfg` in its app sub-directory. In this file, each option must be on a separate line. |
| | 257 | |
| | 258 | For example, to change memory allocation, open `%LOCALAPPDATA%\JOSM\app\JOSM.cfg` and add `java-options=-Xmx8192m` (for 8 GB) to a new line under the `[JavaOptions]` header. |

| | 260 | ==== Graphics ====#MicrosoftWindowsGraphics |
| | 261 | Some Windows installations have graphics driver issues (see #23784 for an example). This may exhibit symptoms such as: |
| | 262 | * Black bars in JOSM toolbars |
| | 263 | * Flickering |
| | 264 | * Other unexpected user interface issues |
| | 265 | |
| | 266 | 1. Download and install Display Driver Uninstaller (DDU, [https://github.com/Wagnard/display-drivers-uninstaller source]) from the official mirror => https://www.wagnardsoft.com/display-driver-uninstaller-DDU- |
| | 267 | 2. From the "Device Type" drop-down on the right, select "GPU". DDU will automatically detect the GPU you're using. |
| | 268 | 3. Click on "Clean and Restart" at the top. This will uninstall the graphics drivers and restart your PC. |
| | 269 | 4. Reinstall the drivers. |
| | 270 | |
| | 271 | //**WARNING: Create a backup of your PC before using DDU. Although it creates a recovery point by itself, it's ideal to make one yourself just in case.**// |
