I developed dynamic web project. I executed the application multiple times. But presently when i try to clean the project(Project->clean->My Project) it is showing some internal problem.. Validation of the project failed.
This is because of when spring beans instantiation the out of memory occured.
The error message is
The stack trace is
java.lang.OutOfMemoryError: Java heap space at org.eclipse.wst.xml.core.internal.parser.XMLStructuredRegionFactory.createRegion(XMLStructuredRegionFactory.java:31) at org.eclipse.wst.xml.core.internal.parser.XMLSourceParser.createStructuredDocumentRegion(XMLSourceParser.java:110) at org.eclipse.wst.xml.core.internal.parser.XMLSourceParser.parseNodes(XMLSourceParser.java:358) at org.eclipse.wst.xml.core.internal.parser.XMLSourceParser.getDocumentRegions(XMLSourceParser.java:164) at org.eclipse.wst.sse.core.internal.text.StructuredDocumentReParser._core_reparse_text(StructuredDocumentReParser.java:309) at org.eclipse.wst.sse.core.internal.text.StructuredDocumentReParser.core_reparse(StructuredDocumentReParser.java:708) at org.eclipse.wst.sse.core.internal.text.StructuredDocumentReParser.reparse(StructuredDocumentReParser.java:1352) at org.eclipse.wst.sse.core.internal.text.StructuredDocumentReParser.reparse(StructuredDocumentReParser.java:1284) at org.eclipse.wst.sse.core.internal.text.BasicStructuredDocument.updateModel(BasicStructuredDocument.java:2705) at org.eclipse.wst.sse.core.internal.text.BasicStructuredDocument.internalReplaceText(BasicStructuredDocument.java:1919) at org.eclipse.wst.sse.core.internal.text.BasicStructuredDocument.replaceText(BasicStructuredDocument.java:2415) at org.eclipse.wst.sse.core.internal.text.BasicStructuredDocument.set(BasicStructuredDocument.java:2927) at org.eclipse.core.internal.filebuffers.ResourceTextFileBuffer.setDocumentContent(ResourceTextFileBuffer.java:579) at org.eclipse.core.internal.filebuffers.ResourceTextFileBuffer.initializeFileBufferContent(ResourceTextFileBuffer.java:290) at org.eclipse.core.internal.filebuffers.ResourceFileBuffer.create(ResourceFileBuffer.java:245) at org.eclipse.core.internal.filebuffers.TextFileBufferManager.connect(TextFileBufferManager.java:113) at org.eclipse.wst.sse.core.internal.FileBufferModelManager.getModel(FileBufferModelManager.java:656) at org.eclipse.wst.sse.core.internal.model.ModelManagerImpl._doCommonGetModel(ModelManagerImpl.java:569) at org.eclipse.wst.sse.core.internal.model.ModelManagerImpl._commonGetModel(ModelManagerImpl.java:536) at org.eclipse.wst.sse.core.internal.model.ModelManagerImpl._commonGetModel(ModelManagerImpl.java:509) at org.eclipse.wst.sse.core.internal.model.ModelManagerImpl.getModelForRead(ModelManagerImpl.java:1438) at org.eclipse.wst.sse.core.internal.validate.ValidatorGroupListener.validationStarting(ValidatorGroupListener.java:72) at org.eclipse.wst.validation.internal.ValManager$2.run(ValManager.java:847) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.wst.validation.internal.ValManager.notifyGroupListenersStarting(ValManager.java:845) at org.eclipse.wst.validation.internal.ValManager.accept(ValManager.java:800) at org.eclipse.wst.validation.internal.ValManager.validate(ValManager.java:667) at org.eclipse.wst.validation.internal.ValBuilderJob$Visitor.visit(ValBuilderJob.java:298) at org.eclipse.core.internal.resources.Resource$2.visit(Resource.java:108) at org.eclipse.core.internal.resources.Resource$1.visitElement(Resource.java:60) at org.eclipse.core.internal.watson.ElementTreeIterator.doIteration(ElementTreeIterator.java:82) at org.eclipse.core.internal.watson.ElementTreeIterator.doIteration(ElementTreeIterator.java:86)

You have to increase your memmory setting for eclipse. There are two ways.
1)Add extra JVM parameters while calling eclipse 2)Edit eclipse.ini. In this approach don't need to pass parameters
Open your eclipse.ini which can be found in eclipse install directory. Modify the -xmx to a higher value.
eg
-startup
plugins/org.eclipse.equinox.launcher_1.0.100.v20080501.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.0.100.v20080428-1330
-showsplash
org.eclipse.platform
-vm
/usr/lib/jvm/java-1.5.0-sun/jre/bin/java
-vmargs
-Xms512m
-Xmx1024m
-XX:+UseParallelGC
-XX:PermSize=256M
-XX:MaxPermSize=512M
