the JVM can use 2 different kinds of memory: heap memory and out-of-heap memory, heap memory is fully allocated and freed by the JVM, and if the program does not have defective code causing memory leaks, then you will not encounter java.lang.OutOfMemoryError this error. The

The exception issues are as follows:1. Click Eclipse->window->preferences, as shown below:2. Click Server->runtime environments, select Apache Tomcat v7.0, and click the Edit button as shown:3. Select the running JRE, click Installed JREs, as shown in:4. Select jdk1.7.0_67, click Edit as shown:5. Locate the default VM Arguments, enter:-xms512m-xmx1024m-xx:maxpermsize=512m in the input box, and then Finish->ok->ok.Next point to the theory of the Proble

The method of adjusting eclipse memory on the internet indicates that the JVM parameters can be set in the Eclipse.ini file. But running the program still found that the memory has not changed, not the set of 1024M, but still 107M (the default program in Eclipse JVM configuration is:-xms8m-xmx128m).The reason for the e

Looking deep into the JVM virtual machine book (p50,2.4 combat OutOfMemoryError), there is a Java heap Overflow example, the use of the Eclipse Memory Analyzer plug-in, because they are now using MyEclipse, So you need to add plugins on the MyEclipse. The steps are as follows:1. Install the mat plugin first Memory
