------ Solution ----------------------- ---------------------
java.lang.OutOfMemoryError: Java heap space

how much you put the items into ah ? Memory overflow when it actually starts . . .


If your code does not create an object of the class infinite loop problem , then try to enlarge it Tomcat memory , add the boot parameter :
-Xmx512m

such as looking Catalina.bat, then modify :
set JAVA_OPTS =-Xmx512m

------ Solution ------------------------------------ --------
Caused by: java.lang.OutOfMemoryError: Java heap space
tomcat memory allocated too little memory overflow , modify Catalina.bat file Specific reference http://www.360doc.com/content/11/0628/21/3804236_130206311.shtml

2 Floor positive solution
------ Solution ----------------- ---------------------------
you here quoted a heap overflow. Add -Xms value.
Another look at the project where there is not no use of the package, how have not loaded his bag before they reported heap overflow of it ? Before setting the value of the landlord or too small ?
------ Solution ---------------------------------------- ----
common phenomenon also encountered the last time I start to change the configuration of the memory size is OK
------ Solution ---------- ----------------------------------
java.lang.OutOfMemoryError: Java heap space
virtual machine memory is not enough , is not returned by the query result set is too large
------ Solution -------------------- ------------------------
agree to the second floor to speak with an estimated program where you are mistaken, cause such a problem similar to the cycle of death .
memory is exhausted. Default environment configuration is not the case. So be sure a procedural issue .

If you are using spring mvc , see if configure web.xml spring of *. htm , if / then remove the test try

Tomcat7.0 and comes with jdk6.0 version Myeclipse inconsistent, own jdk7.0 add to the mix , replaced the jdk6.0,
