Does anyone know what is going on with this?

The jar package loaded at WebLogic startup is as follows.

java.class.path = D:\zonyapps\applibs\commons-logging.jar;D:\zonyapps\applibs\log4j-1.2.8.jar;D:\zonyapps\applibs\activation.jar;D:\zonyapps\applibs\antlr-2.7.6.jar;D:\zonyapps\applibs\aspectjrt.jar;D:\zonyapps\applibs\aspectjweaver.jar;D:\zonyapps\applibs\axis.jar;D:\zonyapps\applibs\cglib-nodep-2.1_3.jar;D:\zonyapps\applibs\commons-collections-3.1.jar;D:\zonyapps\applibs\commons-discovery.jar;D:\zonyapps\applibs\commons-io-1.3.2.jar;D:\zonyapps\applibs\dom4j-1.6.1.jar;D:\zonyapps\applibs\ejb3-persistence.jar;D:\zonyapps\applibs\hibernate-annotations.jar;D:\zonyapps\applibs\hibernate-commons-annotations.jar;D:\zonyapps\applibs\hibernate3.jar;D:\zonyapps\applibs\javassist-3.9.0.GA.jar;D:\zonyapps\applibs\jaxrpc.jar;D:\zonyapps\applibs\jdom-1.0.jar;D:\zonyapps\applibs\jta-1.1.jar;D:\zonyapps\applibs\proxool-0.9.1.jar;D:\zonyapps\applibs\proxool-cglib.jar;D:\zonyapps\applibs\saaj.jar;D:\zonyapps\applibs\slf4j-api-1.5.8.jar;D:\zonyapps\applibs\slf4j-nop-1.5.8.jar;D:\zonyapps\applibs\spring.jar;D:\zonyapps\applibs\sqljdbc4.jar;D:\zonyapps\applibs\standard.jar;D:\zonyapps\applibs\wsdl4j.jar;D:\zonyapps\applibs\adobe-assembler-client.jar;D:\zonyapps\applibs\adobe-generatepdf-client.jar;D:\zonyapps\applibs\adobe-livecycle-client.jar;D:\zonyapps\applibs\adobe-usermanager-client.jar;D:\Oracle\MIDDLE~1\patch_wls1211\profiles\default\sys_manifest_classpath\weblogic_patch.jar;D:\Java\JDK16~1.0_4\lib\tools.jar;D:\Oracle\MIDDLE~1\WLSERV~1.1\server\lib\weblogic_sp.jar;D:\Oracle\MIDDLE~1\WLSERV~1.1\server\lib\weblogic.jar;D:\Oracle\MIDDLE~1\modules\features\weblogic.server.modules_12.1.1.0.jar;D:\Oracle\MIDDLE~1\WLSERV~1.1\server\lib\webservices.jar;D:\Oracle\MIDDLE~1\modules\ORGAPA~1.1/lib/ant-all.jar;D:\Oracle\MIDDLE~1\modules\NETSFA~1.0_1/lib/ant-contrib.jar;;

 

The operating system is Windows, using the Windows service method to start

Solution:

1, check whether the jar package is normal, has not been damaged?

If the jar package is corrupted, weblogic can’t read the contents of the jar package, so decompress the jar package and then compress it to solve the problem.

2, see the weblogic startup jdk and the project compiled jdk is not unified?

It is said that this is because the loaded package is not recognized by jvm. For example, if you develop with IBM’s JDK, you deploy with sun jdk compiled package will appear this situation

3, to see if the project jar and weblogic comes with the jar package has a conflict

There is a saying that weblogic may come with some jar, the project also has some jar package, the version of these jar packages may not be consistent, such as the project than the weblogic version is higher, generally on the weblogic will only load a jar, regardless of the version, so the priority load the project jar
