Jboss 7 war deployment failed

by

Well I tried deleting the log file, it helped at the beginning but then I got the error again. The proper solution is as following: Go to Jboss_installation_dir\standalone\configuration and find the file standalone.xml. Change the following line: <subsystem xmlns=”urn:jboss:domain:deployment-scanner:1.0″> <deployment-scanner scan-interval=”5000″ relative-to=”jboss.server.base.dir” path=”deployments” /> </subsystem> into: <subsystem xmlns=”urn:jboss:domain:deployment-scanner:1.0″> <deployment-scanner scan-interval=”5000″ relative-to=”jboss.server.base.dir” path=”deployments” deployment-timeout=”1000″ /> </subsystem> … Read more

spring-boot without parent pom.xml cannot generate war packaging

by

You removed the parent, so you lost its declaration of the WAR plugin configuration. Here it is: <plugin> <artifactId>maven-war-plugin</artifactId> <configuration> <failOnMissingWebXml>false</failOnMissingWebXml> </configuration> </plugin> See here for the source code. N.B. this is not necessary with Spring Boot 2.0 parent pom and above (the war plugin version is different), or if you use the latest war … Read more

by

The answer is that you are using repackage goal in your spring-boot-maven-plugin. So, What it does? Maven first builds your project and packages your classes and resources into a WAR (${artifactId}.war) file. Then, repackaging happens. In this goal, all the dependencies mentioned in the pom.xml are packaged inside a new WAR (${artifactId}.war) and the previously … Read more

You’ve answered yourself correctly: <profiles> <profile> <id>dev</id> <properties> <rp.build.warname>dev</rp.build.warname> </properties> </profile> <profile> <id>qa</id> <properties> <rp.build.warname>qa</rp.build.warname> </properties> </profile> <profile> <id>prod</id> <properties> <rp.build.warname>prod</rp.build.warname> </properties> </profile> </profiles> but there is a simpler way to redefine WAR name: <build> <finalName>${rp.build.warname}-somearbitraryname</finalName> <!– … –> </build> No maven-war-plugin is needed.

How can I store Java EE configuration parameters outside of an EAR or WAR?

by

See this question for reading properties file outside of the WAR file. See this question for reading variable values from JNDI. I believe that this is the best solution. You can read a String variable with this code: Context initialContext = new InitialContext(); String myvar = (String) initialContext.lookup(“java:comp/env/myvar”); The above code will work on all … Read more
