Answer 1

如果您在Linux环境中启动APIM，请验证wso2server.sh文件是否具有以下配置。

wrapper.java.additional.26 = -Dwso2.carbon.xml=${carbon_home}\\repository\\conf\\carbon.xml
wrapper.java.additional.27 = -Dwso2.registry.xml=${carbon_home}\\repository\\conf\\registry.xml
wrapper.java.additional.28 = -Dwso2.user.mgt.xml=${carbon_home}\\repository\\conf\\user-mgt.xml
wrapper.java.additional.29 = -Dwso2.transports.xml=${carbon_home}\\repository\\conf\\mgt-transports.xml
wrapper.java.additional.31 = -Dorg.apache.jasper.compiler.Parser.STRICT_QUOTE_ESCAPING=false
wrapper.java.additional.33 = -Dfile.encoding=UTF8

如果您将APIM作为窗口服务启动，则在carbon 4.4.x中，需要使用以下附加条目更新默认的wrapper.conf文件。

@autowire

您可以在wrapper.conf中验证这些配置，这些配置可以帮助您解决jsp错误。
