  1. Obfuscating means nothing: the information flow and data structure is still very visible. So AOT brings another level of protection. But this thread https://stackoverflow.com/questions/4232283/can-i-use-native-compilation-as-java-obfuscation says by using something like memory dump one or some other advanced method one can easily reverse engineer the Java source code, this means ExcelsiorJet is not safe enough to protect my Java source code ? Your thoughts ?
  2. Great, I'll try that Sorry I come here late, because I believe I have not received any email notifying me of a reply.
  3. So the questions are - Am I doing correctly ? - If yes, then can I do something else to reduce the exe file ?
  4. Thanks for the excellent product. Now I'd like to prevent ExcelsiorJet from copying all the class file of the 3rd party .jar files into my final native (say .exe) file. Say if my code depends on ClassA in lib.jar, I don't want ExcelsiorJet to copy also ClassB, ClassC, ClassD inside that lib.jar into my final to be generated app.exe Versions - Excelsior 15, JDK 1.8.0_144, Tomcat 8.0, How can I do that ? Thanks ----------------------------------------- These are the steps I did to achieve an .exe file 1) Use maven-assembly-plugin to put all depended jars into a single jar named client-jar-with-dependencies.jar <build> <finalName>client</finalName> <plugins> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>exec-maven-plugin</artifactId> <configuration> <executable>java</executable> <arguments> <argument>-Xms512m</argument> <argument>-Xmx512m</argument> <argument>-XX:NewRatio=3</argument> <argument>-classpath</argument> <classpath/> <argument>com.crcc.btx.ClientRunner</argument> </arguments> </configuration> </plugin> <!-- Maven Assembly Plugin --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-assembly-plugin</artifactId> <version>2.4.1</version> <executions> <execution> <id>make-assembly</id> <!-- bind to the packaging phase --> <phase>package</phase> <goals> <goal>single</goal> </goals> <configuration> <!-- get all project dependencies --> <descriptorRefs> <descriptorRef>jar-with-dependencies</descriptorRef> </descriptorRefs> <!-- MainClass in mainfest make a executable jar --> <archive> <manifest> <mainClass>com.crcc.btx.ClientRunner</mainClass> </manifest> </archive> </configuration> </execution> </executions> </plugin> <plugin> <groupId>com.excelsiorjet</groupId> <artifactId>excelsior-jet-maven-plugin</artifactId> <version>1.2.0</version> <configuration> <mainClass>com.crcc.btx.ClientRunner</mainClass> </configuration> </plugin> </plugins> </build> 2) Run the following to have client-jar-with-dependencies.jar mvn clean package 3) Rename the .jar file because Excelsior only takes client.jar as input cp client-jar-with-dependencies.jar client.jar 4) Generate the exe file on Windows mvn jet:build Now I would see that excelsior is busy including 15783 files into the final client.exe file, which is 59 MB. This is too much
