If starting TOPCAT fails with an error likejava.lang.UnsupportedClassVersionError,you have a version of Java that is too old, and you shouldupgrade to Java 8 or later.If you're unable or unwilling to do that and you only have therather ancient Java 6, you can still use TOPCAT versionv4.6-3 or older.
On Unix-like operating systems, download one or other of thesejar files and the startup script topcat into the same directory, then "chmod +x topcat", and you can just run the command: topcatOn non-Unix systems the script won't work, and you can use a command like: java -jar topcat-*.jaror invoke it in some other system-dependent way such as by clicking on it.

For many users, topcat-lite will provide all the featuresthey need. The optional extras provided by topcat-full include:Treeview-like hierarchy browsing
SoG image viewer (though you still need JAI for it to work)
MySpace and SRB remote file browsing for table load/save
Even topcat-full lacks a few of the niche features (proper coordinate handling in SoG, NDF viewing in hierarchy view,parquet support),since these require native libraries; for these you will need theFull Starjava installation described below,or topcat-extra if you just want parquet.
If you want the most comprehensive installation then download andunpack the full starjava tree in one of the following forms:starjava compressed tar archive (219.2M)
starjava zip archive (219.2M)
These archives include related applications such asSPLAT,SoG andTreeview.You can run TOPCAT using the starjava/bin/topcat script(Unix) or by running java -jar starjava/lib/topcat/topcat.jar.
Applications that run on Tomcat 9 and earlier will not run on Tomcat 10without changes. Java EE based applications designed for Tomcat 9 and earliermay be placed in the $CATALINA_BASE/webapps-javaee directory andTomcat will automatically convert them to Jakarta EE and copy them to thewebapps directory. This conversion is performed using theApache Tomcatmigration tool for Jakarta EE tool which is also available as a separatedownload for off-line use.
Users of Tomcat 10 onwards should be aware that, as a result of the move fromJava EE to Jakarta EE as part of the transfer of Java EE to the EclipseFoundation, the primary package for all implemented APIs has changed fromjavax.* to jakarta.*. This will almost certainlyrequire code changes to enable applications to migrate from Tomcat 9 and earlierto Tomcat 10 and later. Amigrationtool is under development to aid this process.

When you install Java (JRE) and try build your app, the build now finds Javas JRE which has everything it is needs to run Java but not build it, this is why the new error is Could not find tools.jar.. The JDK includes the compiler (javac) and tools (like javadoc and jdb) and is what is needed to build your app. You then fixed the second error by forcing gradle (build tool) to look in the correct folder for your JDK.

I was also getting the same error but could not find a single working solution and wasted my whole day after it. Finally, I myself was experimenting with every possibility taking some assistance from different websites such as this one, stack overflow, etc. After a gruesome 10 hrs, I was able to run my program. Here's a complete working solution to tackle the problem once and for all. I am using jdk version 1.8 also known as java se 8. I would recommend using this and not jdk 11(latest till the date this is being written) because jdk 9 onwards do not include jre explicitly(Read more here: -is-the-difference-between-jdk-and-jre). But jdk 8 takes care of it.error which I was getting :java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/ebookshop?useSSL=false at java.sql.DriverManager.getConnection(DriverManager.java:689) at java.sql.DriverManager.getConnection(DriverManager.java:247) at JdbcSelectTest.main(JdbcSelectTest.java:10)The error is due to the reason that although you have downloaded mysql jdbc driver from here( ), if you have ,and unzipped it, you have not placed the executable jar file contained in the driver in its right place. So, while running the compiled java file, jre is not able to find the mysql jdbc driver.Steps to resolve:1. Download the mysql jdbc driver and unzip it (If you have not).2. Open the unzipped folder named mysql-connector-java-8.0.13(version as on today's date) and copy the executable jar file named mysql-connector-java-8.0.13.3. Now if you are doing something with webapps(Using Tomcat server, eclipse, java ee), then go to the location where tomcat files are placed and paste the jar file(mentioned in step 2) in the tomcat\bin\lib, for example in my case it is C:\Users\ujjwa\Desktop\Practice\Winter\apache-tomcat-9.0.14\libIf not working with webapps, then ignore this step.4. Go to the locations where jdk and jre are installed and paste the jar file in the ext directory, for example in my case they areC:\Program Files\Java\jre1.8.0_191\lib\extC:\Program Files\Java\jdk1.8.0_191\jre\lib\ext5. Then recompile the code using the command javac .java6. Then run the file. It should work fine as in my case it was displaying desired output.For starting up with new softwares and their installation, you can follow the links below.1. _howto.html2. _Basic.html#MySQLJDBCDriverInstall3. This link if for common errors during executing and installing the above mentioned sofwares. 4. For starting with eclipse _HowTo.html#eclipse-java-install

This blog post demonstrates how I integrate java APIs into my LoadRunner VuGen scripts. As I will use a blank windows image I will start by the selecting the JDK Version, Sample API, setup VuGen, Create VuGen Script and Run the VuGen Script.
Early Java 8 versions before update 40 are not supported because they haveseveral bugs that might result in JVM crashes when a java agent is active,thus agent will not start on those versions.Similarly, Java 7 versions before update 60 are not supported as they are buggy in regard to invokedynamic.
The agent creates spans for interactions with the MongoDB driver. At the moment, only the synchronous driver (mongo-java-driver) is supported. The asynchronous and reactive drivers are currently not supported.
Passive message handling: when the message handling logic is applied by implementing a passive message listener API (likejavax.jms.MessageListener#onMessage for example), creating the receiver transaction is mostly straightforward as the instrumented APImethod invocation encapsulates message handling. Still, there are two use cases to consider:
The agent instruments any method defined in a package configured in application_packages and annotated with one of the following:org.springframework.scheduling.annotation.Scheduledorg.springframework.scheduling.annotation.Schedulesjavax.ejb.Schedulejavax.ejb.Schedulesjakarta.ejb.Schedulejakarta.ejb.Schedules in order to create a transaction with the type scheduled, representing the scheduled task execution
The agent instruments the run method in a package configured in application_packages of any class extending java.util.TimerTask, and creates a transaction with the type scheduled, representing the job execution
The java.io.FileNotFoundException is a checked exception in Java that occurs when an attempt to open a file denoted by a specified pathname fails. This exception is thrown by the FileInputStream, FileOutputStream, and RandomAccessFile constructors when a file with the specified pathname either does not exist or is inaccessible. 2ff7e9595c
