I tried to install Structr- Neo4j and after I used these commands: C:\Users\IEUser>cd structr-ui-2.0-SNAPSHOT-201603301445.5616c C:\Users\IEUser\structr-ui-2.0-SNAPSHOT-201603301445.5616c>jar xvf structr-ui-2.0-SNAPSHOT-201603301445.5616c.jar structr java -cp lib/*;structr-ui-2.0-SNAPSHOT-201603301445.5616c.jar org.structr.Server

and I've got this error : INFO: Running in asynchronous mode java.lang.NoClassDefFoundError: Could not initialize class org.structr.schema.compiler.NodeExtender at org.structr.rest.service.StructrHttpServiceConfig.loadClass(StructrHttpServiceConfig.java:152) at org.structr.rest.service.StructrHttpServiceConfig.initializeFromProperties(StructrHttpServiceConfig.java:87) at org.structr.rest.service.HttpService.collectServlets(HttpService.java:608) at org.structr.rest.service.HttpService.initialize(HttpService.java:400) at org.structr.core.Services.createService(Services.java:552) at org.structr.core.Services.initialize(Services.java:327) at org.structr.core.Services.initialize(Services.java:299) at org.structr.core.Services.getInstance(Services.java:147) at org.structr.Server.main(Server.java:36) Feb 14, 2017 4:25:52 PM org.structr.core.Services createService SEVERE: Vital service HttpService failed to start: Could not initialize class org.structr.schema.compiler.NodeExtender. Aborting

Could someone help me? Thanks.

It looks like you are running Structr using JRE instead of JDK. Structr needs JDK to dynamically compile classes.

Please refer to the documentation for further details on setting up JDK for Structr.

  • Could you please run `where java` and `where javac` in a command shell and post the result? – ckramp Feb 15 '17 at 13:59

  • It seems you have 2 different versions of java set up in your path and most likely the one under "C:\ProgramData\Oracle\Java\javapath\java.exe" gets called, because it's first in order. Try removing that entry from your java path and see if it works then. – ckramp Feb 16 '17 at 09:10
