问题 I would like to read environment variable or property in every log line from logback.xml. Example if I hit echo "${FOO_INFO}" the result is "FOO_RESULT", this FOO_RESULT I need to print it in the every log line. After adding JAVA_OPTS="-Dfoo.info=${FOO_INFO}" I tried below option:- Option : added and calling %d{ISO8601} [%thread] %-5level %logger{36} ${FOO_INFO}- %msg%n 回答1: The documentation indicates you can include a system property by using a PatternLayout with the property conversion

问题 Considering the following command line java -Xms128m -Xms256m myapp.jar Which settings will apply for JVM Minimum memory ( Xms option) : 128m or 256m ? 回答1: Depends on the JVM, perhaps the version...perhaps even how many paper clips you have on your desk at the time. It might not even work. Don't do that. If it's out of your control for some reason, compile and run this the same way you'd run your jar. But be warned, relying on the order of the options is a really bad idea. public class

问题 I have a tomcat7 service running on windows, Usually in order to configure the Java options I go to Tomcat 7.0\bin\tomcat7w.exe and there in java tab, in java options I print the definition I want, for example -javaagent:... I want to do this through command line or using some script to have it automated, is there any way to achieve this and still run the tomcat as a service? (right now I run tomcat through cmd: "sc tomcat7 start"). Thanks 回答1: See http://tomcat.apache.org/tomcat-7.0-doc

问题 Environment: Linux/Windows7, Java 1.6.0.03/37 or 1.7 I downloaded jenkins.war and after the initial setup using the following script/command, I downloaded some plugins(10-15) and tried to restart Jenkins, it worked. Then, I got some more plugins (30-40 in total) and either I chose Install or download+then+install, Jenkins didn't come up. i.e. using startJenkins.sh (Linux only). Note: On Windows7 Jenkins started as a Windows service. #!/bin/bash export JAVA_HOME=/production/jenkinsAKS/java

Find Java options used by Maven

由 随声附和 提交于 2019-12-08 15:42:41
问题 How can I find which Java options (Xmx, Xms, Xss, etc) are being used by Maven? I've found out that a way to set them is via the environment MAVEN_OPTS. Now I want a way to be assured it's getting the right settings. EDIT: I believe it´s different to this question as I don´t want to see the value of an environment variable. I rather want to see which settings are actually being used by Maven, whether it comes from a env var, settings.xml or other means. EDIT2: I'm also interested in other

how to set JAVA_OPTS for Tomcat in Windows?

I'm trying to set JAVA_OPTS for Tomcat on a Windows machine, but I keep getting an error if I add more than one variable. For example, this works: set JAVA_OPTS="-Xms512M" But this does not: set JAVA_OPTS="-Xms512M -Xmx1024M" It results in the error: Invalid initial heap size: -Xms512M -Xmx1024M Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit. It's as if I can set one variable (-Xmx will also work) but not several. I'm using the instructed setenv.bat file and my Tomcat is 7.0.35. wannabeartist Apparently the correct form is without the
