T24安装后执行tRun EX命令提示找不到类，是否为配置问题？

First off, don't worry—this is a super common snag for new T24 users, especially on Windows where path and environment configs can get finicky. Let's walk through the most likely fixes step by step:

1. Double-check the EX class actually exists #

Even though you confirmed file counts match, let's verify the critical file manually:

• Navigate to %T24_HOME%\classes\com\temenos\t24\
• Look for EX_cl.class (note the underscore in the filename)
• If this file is missing, your copy from TAFJ_HOME to T24_HOME likely failed silently (often due to Windows UAC permissions if you installed to a protected folder like C:\Program Files). Try re-copying the files as an administrator, or reinstall TAFJ pointing directly to your T24_HOME directory to skip manual copying entirely.

2. Validate Environment Variables #

Windows relies heavily on system-wide environment variables for T24/TAFJ to work correctly:

• Open a brand new Command Prompt (old prompts won't pick up new variable changes)
• Run these commands to confirm paths are correct and accessible:

  echo %T24_HOME%
  echo %TAFJ_HOME%
  echo %PATH% | findstr /i "%TAFJ_HOME%\bin"
  

  • Ensure T24_HOME and TAFJ_HOME are set as system variables (not user variables)
  • Make sure %TAFJ_HOME%\bin is in your PATH (this is where the tRun.bat script lives)
  • Avoid spaces or special characters in your installation paths—Windows handles these poorly for Java-based apps like TAFJ. If your paths have spaces, move T24/TAFJ to a clean folder like D:\Temenos\T24 instead.

3. Audit tafj.properties Configuration #

This file (usually in %TAFJ_HOME%\config or referenced via the TAFJ_PROPERTIES variable) controls how TAFJ loads classes:

• Open tafj.properties and verify these key entries:
  • tafj.base.directory=%T24_HOME% (this points TAFJ directly to your T24 installation root)
  • tafj.classpath must include all necessary T24 and TAFJ directories/JARs. For Windows, use semicolons (;) as path separators (not Linux-style colons :):

    tafj.classpath=%T24_HOME%\classes;%T24_HOME%\webapps\t24\WEB-INF\lib\*;%TAFJ_HOME%\lib\*
    

  • Ensure tafj.application.name isn't overriding the EX program (this should typically be left as default or set to your core application name, not EX)

4. Confirm Version Compatibility #

Double-check that your TAFJ version is fully compatible with the Model Bank version you installed. Mismatched versions can cause missing or incompatible class files even if all files are copied correctly. Refer to Temenos's official compatibility matrix for your specific releases.

5. Run tRun from the Correct Directory #

Try executing the command from your %T24_HOME% root directory:

cd %T24_HOME%
tRun EX

This ensures TAFJ picks up the correct local configuration files without path confusion.

6. Rule Out Windows Permissions Issues #

If you installed T24/TAFJ in a protected directory (like C:\Program Files), Windows might block TAFJ from reading class files. Try:

• Moving the installations to a non-protected folder (e.g., D:\Temenos)
• Running Command Prompt as an administrator when executing tRun

If none of these steps work, enable debug logging to get more context:

tRun EX -Dtafj.log.level=DEBUG

The debug logs will show exactly where TAFJ is looking for the EX_cl class, which can pinpoint the missing path or configuration gap.
