Solution to JVM exception problems when using Xmlbean

xml| solve the problem in the program there is a need to manipulate XML where I personally prefer to use Xmlbean. For this reason, I have a xmlbean project in my Eclipse project list for a long time to generate Schema.jar (Xmlbean). But today, after I deployed my locally tested Xmlbean to a weblogic on a server, I hung up the JVM when I called the Xmlbean ... Log:

after deliberation, the discovery might be that the JDK(I used jdk1.5) When compiling the Xmlbean and the Weblogic version I deployed to are different. Modify my Xmlbean project configuration items immediately : 1 Modify the version of the reference JDK to match the target environment. As shown in figure:   2 Modify the ant script that generates Xmlbean :

<?xml version= "1.0" encoding= "UTF-8"?><project name= "Xmlbean" default= "Build_all_schemas" basedir= "." ><taskdef name= "Xmlbean" classname= "Org.apache.xmlbeans.impl.tool.XMLBean"/><target name= "Build_all_schemas" ><xmlbean schema= "schemas" destfile= "Dist/schemaswapcfg.jar" classgendir= "Build" srcgendir= "src" J Avasource= "1.4" /></target></project>

Note:javasource= "1.4", consistent with the reference JDK version. Recompile , and then redeploy the test. ok! -end-
