Using Neo4j embedded in Java applications Error!!

[Shouer.Shen]

Hi
I created a empty project and import the spring`s jar and config the
web.xml, run it , no error !
then I import the jar files in $NEO4J_HOME/lib , run it error , the
log as follow :

Message: Starting Servlet Engine: Apache Tomcat/7.0.22
java.lang.OutOfMemoryError: PermGen space
Exception in thread "main" java.lang.OutOfMemoryError: PermGen space
at java.lang.Throwable.getStackTraceElement(Native Method)
at java.lang.Throwable.getOurStackTrace(Throwable.java:591)
at java.lang.Throwable.printStackTrace(Throwable.java:462)
at java.lang.Throwable.printStackTrace(Throwable.java:451)
at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:469)

When I delete the jar I imported from $NEO4J_HOME/lib , run Ok !

I used the spring 3.2, neo4j 1.7M2 in eclipse!

why?

and in eclipse.ini :

-startup
plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar
--launcher.library
plugins/
org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.100.v20110502
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
1024M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
1024m
--launcher.defaultAction
openFile

I am just asking if you are doing any queries or updates on the database when this occurs. Or is it during startup?

[Shouer.Shen]

Oh !!!

it during startup

I know how to do it well

thanks !

In eclipse , just set window--》preference--》jdk--》installed jres--》
edit--》default VM Arguments

-Xms128M -Xmx512M -XX:PermSize=64M -XX:MaxPermSize=128M

in eclipse.ini set :

org.eclipse.epp.package.jee.product
--launcher.XXMaxPermSize
128M-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
128m-vmargs
