B4J Question Server program template wont compile

[RickV]

Just installed B4J as suggested for server and desktop UI programming.
Started a brand new server project and hit F5 after reading the template code to see what it does and got the following error.
I am using Windows 10.
Any ideas on what went wrong? I set the paths too when the app asked for the paths to java ac or something.

Hoping this post is in the correct forum

Hi there... again...

plz download latest B4J from here...

Learn Cross Platform App Development IoT, Desktop & Server | B4J

B4J is a 100% free programming tool, similar to B4A that generates desktop, server and web applications.

www.b4x.com

and follow the Instructions for OpenJDK 11, then step 2 - configure B4J ... to add path from folder of openjdk

Also it is good to copy - paste the error log like text... into "quotes" from post-toolbar

...For example if you just copy... the exact error and search it at forum... you will find this:

Error occurred during initialization of VM Could not reserve enough space for 2097152KB object heap

Hi.. I am familier with b4a. But new bee for b4j and also for web application. I am trying to develope a web application using b4j When i try to run the project, it gives following error while compiling..... "Error occurred during initialization of VM Could not reserve enough space for 2097152KB...

www.b4x.com

but first of all install the latest version of b4j (9.80) with openjdk...

ps: don;t know ofcourse if you are trying for 32bit... then oracle java 8 and 9.30 of b4j... but follow the instructions for it

If you are using jServer v4.0+ library then you have to use Java 11+.

It requires Java 11+.

1. As written above, code and messages should be posted as text whenever possible.
2. Always use the latest version of B4J.
3. Based on the error message your PC doesn't have enough RAM with the default settings.
Try to add this to the main module:

#VirtualMachineArgs: -Xms256m

Hello again.
I took your advice and downloaded the 32 bit version from the page you refer above as the 64 bit wont install.
I reinstalled the 32 bit version from a ling further down on same page.
Problem still exists.

Also made sure they system has the latest update of Java.... there was a comment about java 11+ I just checked java.com, there is no java 11 on offfer there. Where do I locate please ?

I am not recommending 32bit... if your pc was only 32bit.. better 64bit... openjdk is at products b4j page.

64bit windows system-> download latest b4j with openjdk 11...follow steps written at products page so jserver 4 lib that is ticked at right window with libs must working... if not add the line at your code Erel suggested...

32bit windows-> download b4j 9.30 at the bottom of products page... must find java 8 jdk jre 32bit... May be need to download jserver 3 lib and put it at the right folder.. then refresh... and open your example .. tick the right jserver for 32bit... May be need add the line Erel suggested...

And you were asking yourself... why not having all these at vb6... because it is only 32bit... and limited... I am saying..

Hi agaun
Thanks for your patience. I have downloaded the 32 bit versions as my win 10 must have been installed as a 32 bit version somehow.
At this stage, I will try all of the above. If all this fails, will buy a new pc and start over from scratch everything 64bit.
