無法在 http://localhost:8080/business-central 上啟動 jbpm

Question

我是一名試圖學習jbpm的學生。 老師不會幫助我，所以這是我唯一的希望。

我已安裝 java 13. 服務器啟動，但出現一些錯誤。 在我輸入“ http://localhost:8080/business-central ”后，我得到一個錯誤 404。這只是日志的錯誤（最后）部分，因為整個事情有超過 40 000 個字符，我只允許 30 000 這里：

1. 請按照以下鏈接中的說明進行操作。
2. 使用 H2 數據庫。
3. 請創建環境變量 JAVA_HOME=C:\Program Files\AdoptOpenJDK\jdk-8.0.202.08 和 PATH=%JAVA_HOME%\bin (使用 Java 8)
4. 請將以下條目插入到 JBoss_EAP_Home\standalone\configuration 下的standalone-full.xml

 <system-properties> <property name="org.kie.example" value="true"/> <property name="org.jbpm.designer.perspective" value="full"/> <property name="designerdataobjects" value="false"/> <property name="org.kie.workbench.profile" value="FORCE_FULL"/> <property name="org.kie.server.location" value="http://localhost:8080/kie-server/services/rest/server"/> <property name="org.kie.server.controller" value="http://localhost:8080/business-central/rest/controller"/> <property name="org.kie.server.controller.user" value="<username>"/> <property name="org.kie.server.controller.pwd" value="<password>"/> <property name="org.kie.server.user" value="<username>"/> <property name="org.kie.server.pwd" value="<password>"/> <property name="org.kie.server.id" value="default-kieserver"/> <property name="org.kie.server.persistence.ds" value="java:jboss/datasources/ExampleDS"/> <property name="org.kie.server.persistence.dialect" value="org.hibernate.dialect.H2Dialect"/> </system-properties>

這必須解決問題。

Answer 2

降級到 OpenJDK 11 有所幫助。 以前我使用的是 OpenJDK 13
