| 7 | == Symptoms == | ||
| 8 | |||
| 9 | When installing or launching the iSymphony client from the launch.jnlp file (or from the desktop icon) you get an error message "Java(TM) Web Start Launcher has stopped working": | ||
| 10 | |||
| 11 | [[image:attach:jws_7u7_exception.png]] | ||
| 12 | |||
| 13 | When the problem details are clicked on, you'll see the exception code **"c0000417"** | ||
| 14 | |||
| 15 | [[image:attach:jws_7u7_exception_code.png]] | ||
| 16 | |||
| 17 | == Cause == | ||
| 18 | |||
| 19 | Java 7 Update 7 appears to have a known issue with the "javaws.exe" executable that causes a crash in the Java Web Start launcher preventing the installation from continuing or full launch to occur. | ||
| 20 | |||
| 21 | == Workaround == | ||
| 22 | |||
| 23 | {{info}} | ||
| 24 | This workaround will disable the auto population of the profile location and tenant with FreePBX systems. | ||
| 25 | {{/info}} | ||
| 26 | |||
| 27 | Open the following file on the server in your preferred editor. Make sure to create a **backup** of the file: | ||
| 28 | |||
| 29 | {{code}} | ||
| 30 | /opt/isymphony/server/client/launch.jnlp | ||
| 31 | {{/code}} | ||
| 32 | |||
| 33 | At the top you will see a line that looks like the following: | ||
| 34 | |||
| 35 | {{code}} | ||
| 36 | <jnlp spec="1.0+" codebase="#CODEBASE#" href="launch.jnlp?location=#WIZARDSERVERLOCATION#&tenant=#WIZARDSERVERTENANT#"> | ||
| 37 | {{/code}} | ||
| 38 | |||
| 39 | Modify it to look like the following and save the file: | ||
| 40 | |||
| 41 | {{code}} | ||
| 42 | <jnlp spec="1.0+" codebase="#CODEBASE#" href="launch.jnlp"> | ||
| 43 | {{/code}} | ||
| 44 | |||
| 45 | == Resolution == | ||
| 46 | |||
| 47 | Downgrade to Java 6, Update 35 or higher. Note that the workaround above may also be considered a fix if you do not require tenant and server auto-population but may need to be applied after any iSymphony server upgrade. | ||
| 48 | |||
| 49 | {{info}} | ||
| 50 | We do not recommend any version of Java 7 at the moment due to the current Java Web Start issue and recently discovered exploits in Java 7. | ||
| 51 | {{/info}} | ||
| 52 | |||
| 53 | {{info}} | ||
| 54 | Java 7 will be officially supported when Oracle resolves the JNLP crash issue with URLs that contain HTTP GET parameters. Until then you will need to utilize the workaround if Java 7 is absolutely required. | ||
