you can update your war from the command line using java commands as mentioned here: jar -uvf test.war yourclassesdir Other useful commands: Command to unzip/explode the war file jar -xvf test.war Command to create the war file jar -cvf test.war yourclassesdir Eg: jar -cvf test.war * jar -cvf test.war WEB-INF META-INF
Spring Boot can be told to produce a ‘fat JAR’ which includes all of your module/service’s dependencies and can be run with java -jar <your jar>. See “Create an executable JAR with Maven” here. Spring Boot can also be told to produce a WAR file, in which case you’ll likely choose to deploy it to … Read more
WAR file is just a JAR file, to extract it, just issue following jar command – jar -xvf yourWARfileName.war If the jar command is not found, which sometimes happens in the Windows command prompt, then specify full path i.e. in my case it is, c:\java\jdk-1.7.0\bin\jar -xvf my-file.war
You are trying to copy the war file to a directory below webapps. The war file should be copied into the webapps directory. Remove the mkdir command, and copy the war file like this: COPY /1.0-SNAPSHOT/my-app-1.0-SNAPSHOT.war /usr/local/tomcat/webapps/myapp.war Tomcat will extract the war if autodeploy is turned on.
To get the classpath all by itself in a file, you can: mvn dependency:build-classpath -Dmdep.outputFile=cp.txt Or add this to the POM.XML: <project> […] <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-dependency-plugin</artifactId> <version>2.9</version> <executions> <execution> <id>build-classpath</id> <phase>generate-sources</phase> <goals> <goal>build-classpath</goal> </goals> <configuration> <!– configure the plugin here –> </configuration> </execution> </executions> </plugin> </plugins> </build> […] </project> From: http://maven.apache.org/plugins/maven-dependency-plugin/usage.html This command … Read more
In Java 7 we got Zip File System that allows adding and changing files in zip (jar, war) without manual repackaging. We can directly write to files inside zip files as in the following example. Map<String, String> env = new HashMap<>(); env.put(“create”, “true”); Path path = Paths.get(“test.zip”); URI uri = URI.create(“jar:” + path.toUri()); try (FileSystem … Read more
I think that was my answer mentioning the exploded WAR in the other question. Exploded WARs are easier to navigate and you can deploy ‘parts’ of your application that much quicker (depending on how our Web/App server deals with this), e.g. Replace a single resource like a JSP page. However it can have some drawbacks: … Read more
There’s another option since maven-war-plugin 2.1-alpha-2. In your WAR project: <plugin> <artifactId>maven-war-plugin</artifactId> <version>2.1.1</version> <configuration> <attachClasses>true</attachClasses> </configuration> </plugin> This creates a classes artifact which you can use in the acceptance tests project with: <dependency> <groupId>your-group-id</groupId> <artifactId>your-artifact-id</artifactId> <version>your-version</version> <classifier>classes</classifier> </dependency>
Similar to what Richard Detsch but with a bit easier to follow (works with packages as well) Step 1: Unwrap the War file. jar -xvf MyWar.war Step 2: move into the directory cd WEB-INF Step 3: Run your main with all dependendecies java -classpath “lib/*:classes/.” my.packages.destination.FileToRun
An interesting question. This is just my view on the topic, so take everything with a grain of salt. I have occasionally deployed and managed applications using both servlet containers and embedded servers. I’m sure there are still many good reasons for using servlet containers but I will try to just focus on why they … Read more
